Detailed description of the invention
The present invention is by changing air nozzle structure, adopt straight-through section thus make wind by time form equal nip, and then blowing direction is changed by bending segment again before air-out, thus not only ensure the stability of final air outlet wind speed and it can be made along the blowing of foil traffic direction, be conducive to improving the effect of drying.Below by describing technology contents of the present invention, structural feature in detail, being realized object and effect, accompanying drawing is coordinated to be explained in detail in conjunction with embodiment.
Refer to Fig. 4, the present invention relates to and be a kind ofly coated with the special tuyere with buffer structure of dryer, it comprises air compartment 50, straight-through section 51 and bending section 52; Described straight-through section 51 one end is connected with air compartment 50, and the other end connects one end of bending section 52, and bending section 52 other end sets out air port; Described bending section 52 is arranged in obtuse angle with straight-through section 51.
Thus, be different from air outlet in original tuyere and adopt the mode of dispersion air-out, this patent air nozzle structure first will pass through the wind of air compartment through a straight-through section, because straight-through section is the smooth passage in one end, can fluid be well guided to pass through, there is not the unexpected size variation of ventilation-sectional area in this straight-through section and therefore can not cause eddy current yet, equal nip can be formed on the contrary in straight-through section 51, ensure that the stability of wind speed, after tested, same when wind speed average speed is 8m/min, after adopting structure of the present invention, the wind speed deviation of air outlet is only at ± 0.3m/min.Increasing bending section before air outlet then can make wind directly to blow in foil, then angularly more slow brushes in foil, thus, when this tuyere is applied in coating dryer, due to the wind speed after equal pressures, to stablize the thrust that wind that tuyere blow out formed upwards foil stable, foil there will not be jitter phenomenon in oven interior, avoids the inconsistent problem of coating thin and thick and occurs.
Embodiment one:
In said structure, air compartment 40 cross section of tuyere is isosceles triangle, and described straight-through section is connected on isosceles triangle summit.As general selection, the shape of air compartment 40 can not have an impact to the wind speed of final air outlet blowout wind.If but air compartment is designed to isosceles triangle, there is better mobility in the air compartment 40 that fluid not only can be made to enter tuyere, and make air compartment 40 structure be convenient to produce.
Embodiment two:
In said structure, described straight-through segment length is not less than 20mm.By above-mentioned visible, straight-through section 51 plays a part key in tuyere, and all presses effect in order to ensure it, and the length of straight-through section should be not less than 20mm.Just strengthen identical to the stability principle of outgoing shell as gun barrel, barrel length in theory, therefore longer straight-through section can play better proportionality action to the wind flowed through, but considers actual product applied environment, through repeatedly testing, best, this straight-through segment length 20-28mm is best.
Embodiment three:
Further, also a supporting plate 6 additionally can be set outward at the air outlet of bending segment 52, and curved being formed with is protected along 61 in air compartment 50 direction of the end of supporting plate 6 to tuyere.The longer the better when condition is permitted for the length of this supporting plate 6, can make to be overflowed along supporting plate 6 by the wind energy after air outlet blows out equal pressures thus to be formed an air cushion surface by increasing supporting plate 6, due to the wind speed after equal pressures, to stablize the thrust that wind that tuyere blow out formed upwards foil stable, can better guarantee that foil there will not be jitter phenomenon in oven interior.The problem avoiding coating thin and thick inconsistent to greatest extent occurs.And protection can strengthen the intensity of supporting plate 6 along 61, after avoiding its distortion, damage foil.
Embodiment four:
In order to ensure preferably wind speed, straight-through section should be identical with the internal diameter of bending segment, can avoid the generation of eddy current during distinguished and admirable both mistakes thus.
Embodiment five:
Straight-through section described above and bending section internal diameter should design at 3-5mm as best.
As shown in Figure 2, present invention also offers a kind of coating dryer, it comprises shell body 1, is provided with the drying tunnel that can pass through for foil 200 in shell body 1, be respectively arranged with ipper air chamber 2 and lower air chamber 3 in drying tunnel upper and lower, described ipper air chamber 2 and/or lower air chamber 3 adopt the tuyere of feature described above., can will be applied in as upper tuyere 4, lower air chamber 3 as lower tuyere 5 in ipper air chamber 2 using tuyere separately according to foil 200 uniformity of drying and heating needs herein, upper tuyere 4 and the lower tuyere 5 of room 2 of also can being in the wind, lower air chamber 3 all adopt this structure.Thus be different from the mode of air outlet employing dispersion air-out in original tuyere, by before tuyere air outlet being straight-through section, air-out is risen and is guided through one section of smooth passage, therefore eddy current can not be caused owing to there is not the unexpected size variation of ventilation-sectional area in this straight-through section, in straight-through section 51, wind energy forms equal nip on the contrary, ensure that the stability of wind speed.After tested, equally when wind speed average speed is 8m/min, after adopting structure of the present invention, the wind speed deviation of air outlet is only at ± 0.3m/min.Increasing bending section before air outlet then can make wind directly to blow in foil, then angularly more slow brushes in foil, thus, when this tuyere is applied in coating dryer, due to the wind speed after equal pressures, to stablize the thrust that wind that tuyere blow out formed upwards foil stable, foil there will not be jitter phenomenon in oven interior, avoids the inconsistent problem of coating thin and thick and occurs.
Embodiment six:
In said structure, the air compartment 40 of tuyere 60 is connected with ipper air chamber 2 or lower air chamber 3; And the air outlet of its bending segment is towards Way out, thus guarantee that air-out is brushed along the direction of foil 200.
Embodiment seven:
In said structure, be in the wind room 2 and lower air chamber 3 arrange described tuyere along interval, drying tunnel direction.Make drying course hot blast blow to foil 200 thus more even, ensure better drying effect.
Embodiment eight:
In above-mentioned, the bending section of tuyere and the angle of foil are less than 45 degree, further, if when being provided with supporting plate outside bending section, supporting plate 6 can adopt the angle being approximately parallel to foil 200 to arrange, thus the wind blown out can be made to form one large-area " air cushion " and act in foil 200, reduce the image to slurries, guarantee best drying effect.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
