技术领域 TECHNICAL FIELD
 本发明属于镀锌设备技术领域，涉及一种热浸镀锌设备，所述热浸镀锌设备可以为任何镀件进行镀锌作业，作为一种特例，本发明主要介绍的镀件为角钢。  The present invention belongs to the technical field of galvanizing equipment, relates to a hot-dip galvanizing equipment, the hot-dip galvanizing equipment can be galvanized operation of any plating, as a special case, the present invention is primarily described plating the angle.
背景技术 Background technique
角钢是制作送变电铁塔的主要原材料，由于送变电塔一直暴露在户外，如果对角钢不加以保护，那么用不了多少时间，角钢就腐蚀殆尽，目前增加角钢抗腐蚀能力的一种方法就是给角钢镀上各种保护层，锌就是一种常见的金属保护层，给角钢镀锌常采用热浸镀锌方法，具体是将角钢浸入盛有锌液的锌锅，但热浸镀锌的最大技术缺点就在于镀锌过程中会在短时间内产生大量的锌烟，采用的抽气机往往不能迅速的将锌烟吸走，甚至有部分锌烟滞留在锌锅上方的某些角落中，虽然技术人员往往在锌烟抽除干净时关闭抽气机，但这些未来得及抽走的锌烟仍然会弥漫扩散在锌锅上方，给技术人员的身体造成潜在的威胁，另外一种可能是锌烟可以从某些空隙中散发到外界，造成环境污染。  Transmission and Distribution Tower Angle is making a major raw material, due to the Transmission and Distribution tower has been exposed to the outdoors, if the angle is not protected, it does not take much time, angle to corrosion and exhausted, the current increase in the corrosion resistance of the angle One way is to give a variety of angles plated protective layer, zinc is a common metal protective layer, galvanized angle steel is often used to hot-dip galvanizing method, specifically the angle dipped zinc solution containing zinc pot, but the heat dip galvanized biggest technical drawback is that the galvanizing process will produce large amounts of zinc smoke in a short time, the use of suction machine often can not quickly be sucked smoke zinc, zinc and even some tobacco stuck in the top of the zinc pot some corner, although technicians tend zinc clean shutdown when the smoke pumping air pump, but these have not had time to take away the smoke still filled the diffusion of zinc above the zinc pot, resulting in a potential threat to the technician's body, in addition One possibility is that zinc can smoke emanating from some of the gap to the outside, causing environmental pollution.
发明内容 SUMMARY OF THE INVENTION
 本发明所要解决的技术问题在于镀件在进行镀锌时，会在短时间内产生大量的锌烟，而现有设备无法及时的将锌烟抽走，造成锌烟的残留及扩散，从而对镀锌操作人员及环境构成威胁。  The technical problem to be solved by the present invention is that when plating galvanizing, zinc will produce a lot of smoke during the short period of time, and the existing equipment can not timely zinc tobacco pulled out, causing smoke residue and zinc diffusion , thereby galvanizing operators and environmental threat. 为了解决该问题，本发明充分考察了现有镀锌设备的实际情况，现有技术主要存在的第一个技术问题是，抽气机的抽气力度无法在短时间内将大量产生的锌烟抽走，造成大量锌烟在产生初期来不及向抽气机方向聚集，就向四面八方扩散，使锌烟污染环境的几率大增。 To solve this problem, the present invention fully investigate the actual situation of the existing galvanizing equipment, the first technical problems of the prior art is mainly zinc fume exhaust blower intensity can not be produced in large amounts in a short time take away, causing a lot of zinc to produce smoke too late to gather early in the pumping machine direction, it spread to all sides, so that zinc smoke greatly increased risk of environmental pollution.
 本发明希望能够将这些锌烟在抽气机工作期间限定在一定的空间范围，防止其扩散，为抽气机逐步抽取锌烟积累时间。  The present invention is intended to be able to smoke during these zinc extraction machine working space defined in a certain range, to prevent its spread, as the suction machine to extract zinc smoke gradually accumulated time. 目前，努力实现本发明上述技术设计目标的一种方案是在锌锅上方盖上吸尘罩，大量产生的锌烟就会限制在所述吸尘罩内，技术人员将吸尘罩与抽气机连通后，吸尘罩内聚集的锌烟即可抽走。 Currently, efforts to achieve the above-described technique for program design goals of the present invention is covered with zinc dust cover over the pot, zinc smoke will generate a large number of restrictions in the dust cover, dust cover and technical staff will exhaust machine connectivity, the inner dust cover can be pumped smoke gathered zinc.
 然而，对角钢进行吊挂，使角钢浸入镀锌液或者从镀锌液中提出都需要吊挂部件，而对角钢进行大范围的位置吊运，需要在吸尘罩上开设吊挂通孔，吊挂通孔的宽度应当至少满足吊绳能够顺利从吊挂通孔穿过，对于使用比较广泛的吊挂装置电动葫芦而言，吊挂通孔的宽度应当至少大于缠绕在吊钩上的两条吊绳之间的距离，而锌烟就可以通过吊挂通孔扩散到外界。  However, to be hanging angle, so that the angle dipped galvanized liquid or requires hanging assembly out of the galvanizing bath, while the angle for a wide range of lifting position, you need to set up the hanging dust cover Through Hole, hanging through hole width should meet at least be able to successfully pass through sling hanging from the through hole, for more extensive use of hanging device electric hoist, the hanging through hole width should be at least greater than the wound on the hook the distance between the two sling, while zinc smoke can spread to the outside world by hanging through holes.
 作为解决所述第一个技术问题的技术方案，本发明提供了一种热浸镀锌设备，该设备包括锌锅、位于锌锅上方的抽气部件及吊挂部件，所述吊挂部件包括行车、通过葫芦支架在行车上滑动的电动葫芦、顶部设有动滑轮的挂钩件以及钢绳，所述电动葫芦设有钢绳滚筒，所述抽气部件包括罩在锌锅上的吸尘罩以及抽气管道，所述吸尘罩开有连通抽气管道的抽气口以及供钢绳穿过的吊挂通孔，所述钢绳包括工作段以及缠绕在钢绳滚筒上的滚筒段，所述工作段包括固定在葫芦支架上的第一分段、与滚筒段连接的第二分段以及连接第一分段与第二分段的连接段，所述连接段绕在动滑轮上，其特征在于所述吊挂部件还包括抵挡工作段，使第一分段与部分第二分段构成的平面或者第二分段与部分第一分段构成的平面与钢绳滚筒轴向方向平行的抵挡机构，所述抵挡机构包括抵挡工作段的旋转导轮以及穿过旋转导轮轴心的导轮轴，所述导轮轴固定在葫芦支架上。  as a solution to a technical problem the first aspect, the present invention provides a hot-dip galvanizing equipment, which includes a zinc pot, located exhaust components and parts zinc pot hanging above the hanging hanging member including driving, electric hoist line car sliding through hoist bracket, top with a hook member and a movable pulley rope, the hoist drum with a rope, the pumping section comprising a cover on the pot zinc absorption dust cover and exhaust pipes, the dust cover open communicating the exhaust port and the exhaust pipe for the hanging rope through holes through which the rope segment includes work on the rope wrapped around the drum and the drum section , the working section comprises a bracket secured to the hoist first segment, a second segment connected to the drum and a segment connecting the first and second section of the connecting section, the connecting section is wound around the movable pulley, wherein said hanger means further comprises a resist working section, with the flat portion of the second segment constituting the first segment or the second segment and the plane with the rope portion constituting the cylinder axial direction parallel to the first segment resist mechanism, the mechanism comprises withstand and resist the rotating guide wheel through the rotation of the guide shaft center section of the guide shaft work, said guide shaft is fixed to the hoist bracket.
 采用上述方案后，旋转导轮可以抵住第一分段，也可以抵住第二分段，这两种方式都可以使第一分段与部分第二分段构成的平面或者第二分段与部分第一分段构成的平面与钢绳滚筒轴向方向平行，从而吊挂通孔的宽度可以大幅度的下降，使锌烟从吊挂通孔逃逸的机率大大下降。 After the  With the above scheme, rotating guide wheel against the first segment can be against the second segment, these two methods can make the plane formed part of the second segment of the first subparagraph or the first Second segment with the plane and the axial direction of the rope drum formed part of the first sub-parallel, thereby hanging through hole width can be greatly decreased, so that zinc smoke escaping through holes from hanging chances greatly reduced.
 旋转导轮通常都至少包括两个圆盘以及两个圆盘之间的沟槽，为方便说明，第二分段在旋转导轮沟槽上缠绕的部分称为缠绕段，在挂钩件吊挂角钢的过程中，第一分段与第二分段之间始终存在一定的角度，显然第二分段中，连接段与缠绕段之间的部分会随着钢绳卷出或卷入旋转导轮而与构成旋转导轮的圆盘边缘摩擦，从而减少钢绳的使用寿命。  The rotating guide wheels usually include at least two disks and a trench between two discs, for ease of illustration, the second segment in the rotation guide groove winding wheel part is called the winding section, the hook pieces hanging angle of the process, there is always between the first and second section a certain angle, obviously the second segment, part of the connection between the segment and the segment wrapped with rope will roll out or roll the rotating guide rollers and constituting the edge of the friction disk rotating guide wheel, thereby reducing the service life of the rope.
 一种可靠的改进方式试图使钢绳在卷出或卷入旋转导轮时，杜绝钢绳与构成旋转导轮的圆盘碰触，例如所述旋转导轮包括导轮偏移机构以及偏移平衡机构，所述偏移机构包括导轮本体、套在导轮轴上的直线轴承以及位于导轮本体及直线轴承之间滚动的若干滚珠，所述偏移平衡机构包括位于导轮本体两侧的两个套在直线轴承上的抵挡套以及两个弹簧，所述弹簧一端抵住抵挡套，另一端抵住导轮本体，所述抵挡套与直线轴承相对固定。  A reliable way to improve the rope when trying to roll out or involved rotating guide wheel, put an end to the rope and constitute rotating disc tumbler touch, such as the rotating guide wheel guide wheel offset mechanism comprises and the offset balance mechanism, the shift mechanism includes a guide wheel body, a plurality of sets the ball rolling on the guide shaft between the linear bearings and guide wheel located on the body and linear bearings, the offset balance mechanism includes a guide wheel body Two sets of linear bearings on both sides of the sleeve to resist and two springs, one end of the spring against the resist cover, and the other end against the guide wheel body, the sleeve and linear bearings to withstand relatively fixed. 一旦钢绳与构成旋转导轮的圆盘碰触，所述导轮本体将会随着钢绳碰触圆盘的方向发生整体角度偏移，角度偏移的程度由两个位于导轮本体两侧的弹簧弹力及钢绳施加在圆盘上的力大小决定，技术人员可以容易的实现:调节导轮本体两侧弹簧的弹力使导轮本体整体的偏移角度大于等于第一分段与第二分段之间的夹角。 Once the rope constituting the disc rotating guide wheels touch, the guide pulley rope touch with the body will occur overall direction of the disk angular offset, angle offset level by two guide wheels located two body side spring force and steel 绳施加 force size is determined on the disc, the technician can easily achieve: adjusting the spring guide wheels on both sides of the body as a whole body stretch so that the guide wheel offset angle is greater than equal to the first segment of the first the angle between two segments.
 另一种可靠的改进方式试图使钢绳在卷入旋转导轮的过程中，能够顺利的卷入构成旋转导轮的沟槽，至少由于滚筒段钢绳在滚出钢绳滚筒而转变成第二分段中缠绕段与滚筒段之间的部分与旋转导轮沟槽并不共面，因此也会存在该部分与构成旋转导轮的圆盘发生摩擦，或者更为严重的情况是，所述第二分段中缠绕段与滚筒段之间的部分直接脱离旋转导轮沟槽。  Another reliable way to try to make improvements in the involvement of the rope in the process of rotating guide wheel, smooth grooves constitute involvement rotating guide rollers, at least since the drum section of the rope in the rope to get out of the drum and into a portion of the rotating guide wheel groove wound segment of the second segment of the drum between the segments are not coplanar, so the situation disc rotating guide wheel portion constituting the friction, or there will be more serious that portion of the winding section of the second segment of the drum between segments directly from the rotating guide wheel grooves.
 本发明为此引入了另一种抵挡结构，即在原有的抵挡机构上增设与旋转导轮两端连接的同步拨叉以及将第二分段向旋转导轮方向抵的抵轴，所述抵轴两端与同步拨叉连接。  To this end the present invention introduces another resist structure, namely the addition of synchronous rotating guide wheel fork and connected to both ends in the original resist the institution and the second segment to the direction of rotation of guide rollers abuts against the shaft, the abutting ends of the shaft is connected with synchronous fork. 该结构的最大优点在于将所述第二分段中缠绕段与滚筒段之间的部分分为两个小分段，确保与缠绕段连接的小分段与构成旋转导轮的沟槽共面。 The biggest advantage of this structure is that the portion of the segment of the wound and the drum section between the second segment is divided into two subsections, to ensure that small segments constituting the trench coplanar rotating guide wheel connected with the winding section .
 进一步的改进方案是增加导绳器，使导绳器与同步拨叉为一体结构。  A further improvement is to increase the lead rope, so that the guide rope and synchronous fork into one structure. 导绳器内部开有供钢绳穿过的通孔，滚筒段钢绳通过导绳器通孔转变成第二分段钢绳，导绳器会随着滚筒段钢绳卷出钢绳滚筒的位置变化而发生实时的移动。 Guide rope inside with holes for the rope through the drum section rope through the rope guide through holes into the second segment rope, lead rope will roll out of the drum section rope rope drum moving in real time the position changes occur.
 由此可见，采用本发明所述吊挂部件，是可以极大的减少锌烟逃逸的可能性，并且所述吊挂部件的运行方式是稳定可靠的。  Thus, the use of the hanging member of the present invention, it is a great possibility to reduce zinc smoke can escape, and the hanging member operating mode is stable and reliable.
 锌烟在向抽气管道与吸尘罩连接的抽气口方向运动时，会自发的向四周扩散，现有技术存在的第二个问题就是，吸尘罩总是存在这样一个与外界连通的区域，至少在抽气机抽锌烟的某一时段内，锌烟通过该区域向外界扩散的速度比抽气机从该区域抽走锌烟的速度要快，从而无法避免锌烟从该区域扩散至外界的风险。  When zinc fume exhaust port to the exhaust pipe and the direction of movement of the suction hood is connected, it will spontaneously spread to the surrounding, the second problem of the prior art is that there is always such a dust cover with the outside world communication within the region, drawn by suction at least in a certain period of zinc smoke, smoke zinc diffusion through the region to the outside world faster than suction machine pumped zinc smoke from the area faster, making it impossible to avoid the smoke from zinc risk of proliferation in the region to the outside world.
 在很多情况下，上一段所述与外界连通的区域即为吊挂通孔，本领域技术人员可以将吊挂通孔设置在接近抽气口的接近区域，在这样的区域中，抽气口的抽力可以使该区域的气压下降，从而外界空气有通过接近区域进入吸尘罩的倾向，但另一方面，锌烟气流由于抽气吸力的作用将会以较快的气流速度通过抽气口，并会对所述接近区域造成冲击，一个比较常见的现象是尽管有外界空气通过接近区域进入吸尘罩内，但仍然会有部分锌烟通过接近区域逃逸到外界。  In many cases, communication with the outside of the area over the period is suspended through holes, one skilled in the art can be hung near the suction through holes provided in the area close to the mouth, in such areas, pumping air inlet pumping power can decrease the pressure in the region, which tends to the outside air into the region by approaching dust cover, but on the other hand, zinc flue gas stream due to the pumping suction flow rate will be faster through exhaust port, and have the closest regional impact, a more common phenomenon is that in spite of outside air into the dust cover by approaching the area, but there will still be part of the zinc smoke escapes to the outside world through proximity area. 本领域技术人员也可以将吊挂通孔设置在远离抽气口的远离区域，在远离区域，外界空气通过远离区域进入吸尘罩的趋势以及锌烟气流通过远离区域逃逸至外界的趋势都大幅减弱了，尽管如此，本领域技术人员仍然可以发现锌烟通过远离区域逃逸至吸尘罩外界。 Skilled in the art can also be hung through holes provided in the far region away from the suction port, away from the area, outside air into the dust cover through the area away from the flue gas stream through the trend and the trend away from the zinc to escape to the outside of the area have substantially weakened, however, those skilled in the art can still be found in zinc smoke to escape through the dust cover away from the area outside.
 本发明发现，外界空气通过吊挂通孔进入吸尘罩的流速应当至少为锌烟通过吊挂通孔扩散至外界速度的2.6倍，这样才可以从根本上杜绝锌烟从吸尘罩内逃逸。  The present inventors have found that, outside air into the dust cover by hanging through hole flow rate should be at least zinc smoke hanging vias through diffusion to 2.6 times the speed of the outside world, so that it can prevent the smoke from the fundamental zinc from dust escape the inner cover. 然而，锌烟通过吊挂通孔扩散至外界的速度与空气由吊挂通孔进入吸尘罩的速度，在相当程度上和吊挂通孔与抽气口之间的距离表现出比较一致的关联性，从而很难使外界空气通过吊挂通孔进入吸尘罩的流速达到锌烟通过吊挂通孔扩散至外界速度的2.6倍。 However, zinc smoke hanging vias through the speed and spread to the outside air from entering the dust cover hanging vias speed, and distance to a certain extent through hole and sucking mouth hanging between exhibits relatively consistent association sex, making it difficult to make the outside air into the flow rate reaches the zinc dust cover smoke hanging vias through diffusion to 2.6 times the speed of the outside world by hanging through hole. 正是因为本发明对吊挂部件进行了改进，缩小了吊挂通孔的宽度，极大的提高了吊挂通孔宽度的可调整范围(尤其使吊挂通孔在相当小的宽度范围(例如可设置在20cm以内)内的调整变成了可能)。 It is precisely because of the hanging part of the present invention has been improved, narrowing the width of the through hole hanging, which greatly improves the through-hole width hanging adjustable range (especially so hanging through hole in a relatively small width ( for example, set within 20cm adjustment) inside becomes possible). 技术人员通过缩小吊挂通孔宽度即可增加空气由吊挂通孔进入吸尘罩的速度。 Technical personnel to increase the through hole into the air from the hanging dust cover speed through narrow hanging through hole width.
 一般的，吊挂通孔与抽气口之间的距离为3.2m-4.6m，吊挂通孔的宽度为33cm-47cm,所述吸尘罩的宽度为2.7m_3.6m。  The general hanging through hole distance between the exhaust port for the 3.2m-4.6m, width hanging through hole is 33cm-47cm, width of the dust cover 2.7m_3.6m. 优选的吊挂通孔与抽气口之间的距离为3.7m-4.1m,吊挂通孔的宽度为35cm_42cm，从而使外界空气通过吊挂通孔进入吸尘罩的流速达到锌烟通过吊挂通孔扩散至外界速度的3.2倍以上。 Preferred hanging from the through-hole and between the exhaust port 3.7m-4.1m, width hanging through hole is 35cm_42cm, allowing outside air to enter the flow rate through the dust cover through hole reaches zinc smoke hanging by hanging vias spread to the outside world more than 3.2 times the speed.
 虽然本发明对吊挂部件的改进已经使减少吊挂通孔宽度的潜力得到极大的发挥，理论上可以无限制的接近钢绳的口径，但一方面制作好的吊挂通孔宽度无法微调，而对吊挂通孔进行微调是一项比较重要的技术手段，在相当大的程度上，能够弥补吊挂通孔的宽度与吊挂通孔和抽气口之间距离不配套而产生锌烟扩散逃逸的风险，另一方面将吊挂通孔的宽度设置成接近钢绳口径的宽度增加了钢绳对吊挂通孔的摩擦风险，降低钢绳的使用寿命O  While hanging member has made the improvement of the present invention to reduce the width of the potential hanging vias greatly to play close to the rope diameter can theoretically unlimited, but one making a good hanging through hole width can not be fine-tuning, and fine-tuning for hanging through hole is a more important technical means, to a large extent, be able to compensate for the width of the hanging between vias and through holes sucking mouth hanging distance is not complete and the risk of zinc diffusion smoke escape, on the other hand will be hanging through hole width is set to be close to the width of the rope diameter increases the rope through holes for hanging friction risk and reduce the life of the rope O
 因此更好的方案是在吊挂通孔上用其他遮盖物盖住，在本发明的一些实施例中，就采用了这样的遮盖物，所述遮盖物为抽气部件增设的开有缝隙并固定在吸尘罩上的柔性条，钢绳通过缝隙穿过吊挂通孔。  Therefore, a better solution is to cover the hanging through hole other shelters, in some embodiments of the present invention, on the use of such a covering, the covering member is pumping additional open There are gaps and dust cover fixed flexible strip of rope hanging through the gap through the through hole. 柔性条的设置可以大量的减少对钢绳穿过所述缝隙的磨损，还可以进一步减少锌烟逃逸的可能性。 Settings can significantly reduce the flexibility of the rope through the gap to wear, can further reduce the possibility of zinc smoke escape.
 作为一种优选，所述柔性条由橡胶制成，整体呈波浪形，也即柔性条呈被挤压的状态，在钢绳不经过的时候，所述缝隙两侧的柔性挤压面相互挤压，从而可使缝隙不透气。  As a preferred, the flexible strip is made of rubber, the overall wavy, i.e. flexible strip was extruded state, without rope when the slits on both sides of the flexible squeeze face pressed against each other, thereby allowing the gap airtight.
 增设柔性条不但可以作为一种吊挂通孔与吊挂通孔和抽气口不配套的补救措施，也可以在不考虑吊挂通孔与吊挂通孔和抽气口配套问题上单独在吊挂通孔上使用。  The additional flexible strip not only be used as a hanging and hanging through hole vias and exhaust ports not supporting the remedy is not considered to be in the through-hole and hanging on the hanger through hole and exhaust outlet is equipped with a separate issue Use the hanging through hole.
 在镀锌过程中产生的锌烟具有较大的密度，造成比较慢的扩散速度，增加锌烟抽气的力度是最简便的方法，所产生的技术效果也是立竿见影的。  The smoke generated in the zinc galvanizing process has a greater density, resulting in relatively slow diffusion rate, increase the intensity of the zinc fume exhaust is the most convenient way, the technical effect produced is immediate. 然而总有一小部分锌烟附着在镀锌液面上，并达到某种平衡，在抽气机停止抽气后，只要对镀锌液进行扰动，附着在镀锌液面上的锌烟就会散发到吸尘罩内，并最终逃逸到外界。 However, there is always a small part attached to the galvanized zinc liquid smoke, and achieve a balance, after pumping stopped pumping, as long as the galvanizing solution was perturbed, attached to the surface of the zinc galvanizing smoke will circulated into the dust cover, and eventually escape to the outside world.
 本发明建议在抽气时增加对锌烟气流的推动力，防止锌烟特别是离抽气口位置较远的锌烟因自身较大的密度而发生沉降现象，所述推动力可以由大功率的抽气机产生，但大功率的抽气机对离其较远的锌烟所施加的作用力非常有限，因此更加推荐采用由抽气带动的外界气流来推动锌烟向抽气口的方向扩散。  The present invention proposes to increase the driving force for zinc flue gas stream at the time of evacuation, in particular, to prevent the zinc fume exhaust port locations distant from zinc smoke density due to their own larger settlement phenomenon occurs, the driver can generated by the high-powered suction machine, but high-powered blower to force it farther away from the smoke of the applied zinc is very limited, so more is recommended driven by the exhaust gas flow to the outside world to promote zinc fume exhaust port The direction of diffusion.
 本发明首先试图通过外界气流使附着在镀锌液面上的锌烟与镀锌液面剥离，为了制造由抽气带动的外界气流，可以营造了一种相对密闭的空间，本发明对吸尘罩进行了改进，在吸尘罩底部设置了与锌锅顶部连接的连接端，所述相对密闭的空间就被吸尘罩及锌锅封闭，但所述相对密闭的空间可以通过连接端改变其密闭性，例如可以将至少部分连接端转化为门窗。  The present invention first attempts to make the airflow attached to the outside surface of galvanized zinc galvanizing liquid smoke and peeled, to manufacture exhaust driven by the airflow outside, you can create a relatively confined space, the present invention for improved dust cover, dust cover is provided at the bottom of the connecting terminal connected to the top of the zinc pot, the relatively confined space is sealed dust cover and zinc pot, but the relatively confined space can be connected end change its airtight, for example, at least part of the connecting end into the doors and windows. 开动抽气机对该相对密闭的空间进行抽气，使所述相对密闭的空间产生较低的气压。 Start the suction machine pumping relatively confined space, so that the relatively confined space produces a lower pressure. 所述连接端至少设有与锌锅液面相对且开口朝向锌锅液面的第一通气口，外界气流通过所述第一通气口直接吹至锌锅液面，使附着在锌锅液面上的锌烟被外界气流带离锌锅液面。 Said connection end with at least a first air vent openings zinc pot surface opposite and facing surface of the zinc pot, outside air flow through the first vent blow directly to the zinc pot surface, so that the liquid attached to the zinc pot Zinc is smoke on the outside surface airflow away from the zinc pot.
 本发明还试图借助外界气流增加锌烟向抽气口方向的推动力，对锌烟进行抽气，吸尘罩内部离抽气口较近的部分区域受抽气机的影响，能够顺利的将锌烟抽至抽气口，而在吸尘罩内部离抽气口较远的部分区域，则为锌烟沉降区，在锌烟沉降区，锌烟则更多的表现出向下沉降或悬浮的趋势，将外界气流对准锌烟沉降区，可以使部分锌烟脱离锌烟沉降区，成功被抽气机抽走，仍无法保证所述锌烟沉降区中的绝大部分锌烟均可以被抽气机抽走。  The present invention also seeks to increase the driving force of zinc fume extraction opening direction by means of the external air stream, a partial area of the zinc fume exhaust, dust cover from the exhaust port close to the internal effects of suction machine that can smoothly zinc cigarette to exhaust port, and some area inside the suction hood exhaust ports farther away, for the zinc tobacco settlement area, tobacco settlement area in zinc, zinc smoke are more exhibited downward trends in the settlement or suspension the outside air flow aligned zinc tobacco settlement area, you can make part of the zinc from zinc smoke tobacco settlement area, successfully pumped pumping machine still can not guarantee the zinc tobacco settlement area the majority of zinc smoke can be pumped air-pumped. 本发明在所述连接端设置了开口方向与锌锅液面成35° -45°角的第二通气口，所述第二通气口可以设置在与锌锅液面相对的位置，也可以设置在锌锅液面上方的位置，优选的方案是将所述第二通气口设置在距离锌锅液面0.3m-0.4m的位置，同时将吸尘罩的高度及宽度分别设置为7.8m-8.9m及2.7m_3.6m，从而使所述第二通气口的开口方向使得外界气流正好对准锌烟沉降区自身高度68% -80%的部位，位于该部位之上的部分锌烟沉降区中的锌烟称为上部锌烟，所述上部锌烟可以迅速的向抽气口运动，而位于锌烟沉降区其余部分中的锌烟称为下部锌烟，所述上部锌烟在由外界气流推向抽气口后，可以在所述上部锌烟原先逗留的空间形成低压，外界气流使所述低压维持足够低的水平，能够带动下部锌烟向抽气口方向运动，并接受外界气流的推动，保证锌烟源源不断的向抽气口方向运动直至吸尘罩内的锌烟基本抽完(锌烟在吸尘罩内的滞留率小于4%，本领域技术人员可以容易的检测锌烟在吸尘罩内的浓度，例如可以采用对射光照烟雾传感器，锌烟在吸尘罩内的滞留率可通过抽锌烟前后锌烟浓度的比值而得出)。 The present invention is provided at the connection end opening direction of the liquid into a pot and zinc 35 ° -45 ° angle of the second vent, said second vent may be provided in a position opposed to the zinc pot surface, can also be set position above the liquid surface of the zinc pot, a preferred embodiment of the second ventilation port is disposed at a distance of 0.3m-0.4m zinc pot liquid level position, while the dust collecting cup height and width are set to 7.8m- 8.9m and 2.7m_3.6m, so that the opening direction of the second ventilation opening such that the outside air flow precisely aligned with zinc tobacco settling zone itself 68% -80% of the height of the portion, the portion located above the tobacco portion of zinc settling zone Zinc Zinc tobacco smoke is called an upper portion, the upper portion of the zinc to the movement of the smoke can quickly exhaust port, while the remaining portion is zinc in zinc tobacco smoke settling zone known as the lower part of the zinc fume, smoke in the upper portion of the zinc air flow from outside After push the exhaust port, a low pressure can be formed in the upper space of the original zinc smoke stay, outside air flow so that the low pressure to maintain a sufficiently low level, it is possible to drive to the lower portion of the zinc fume exhaust port direction of movement, and to accept outside airflow driven Zinc ensure a steady stream of smoke movement direction of the exhaust port until smoke zinc dust hood substantially smoked (zinc smoke retention rate in the dust cover is less than 4 percent, skilled in the art can readily detect smoke in zinc dust concentration inside the hood, for example, can be used to shoot light smoke sensor, smoke retention rate of zinc in the dust cover can be derived) by the ratio of zinc cigarette smoke before and after the smoke concentration of zinc. 如果将外界气流对准锌烟沉降区自身高度80%以上的部位，则所产生的低压无法带动下部锌烟，同样，将外界气流对准锌烟沉降区自身高度68%以下的部位，则会造成另一方景象，即上部锌烟仍然会在向抽气口运动一定距离后沉降。 If the outside air flow aligned zinc tobacco settlement area itself part of the height of more than 80%, a low pressure is generated by the smoke does not bring the lower part of the zinc, the same, the external airflow aligned zinc tobacco settlement area itself highly portion 68% or less, will causing the other party scene, that will still be in the upper zinc smoke exhaust opening movement after a certain distance to the settlement.
 在本发明的一些实施例中，第二通气口的开口方向与锌锅液面成38° -42°角，所述第二通气孔距离锌锅液面0.32m-0.36m，所述吸尘罩的高度为8.2m-8.5m，所述吸尘罩的宽度为3.0m-3.4m，在这些实施例中，所述第二通气口的开口方向使得外界气流正好对准锌烟沉降区自身高度74% -78%的部位，锌烟在吸尘罩内的滞留率将变的更低，达到1%以下。  In some embodiments of the present invention, the opening direction of the second vent with zinc pot surface into 38 ° -42 ° angle, said second vent liquid from the zinc pot 0.32m-0.36m, the the height of said dust cover is 8.2m-8.5m, a width of the dust cover is 3.0m-3.4m, in these embodiments, the opening direction of the second vent such that air flow just outside the alignment zinc tobacco height 74% -78% of their own parts of the settlement area, smoke retention rate of zinc in the dust cover will become lower, up to 1% or less.
