Abstract
The invention discloses a blast drier comprising a material holding box and a heating device. The heating device is vertically arranged at the position of a central axis inside the material holding box, the bottom end of the heating device is connected with an air outlet end of an air blower below the material holding box, and a stirrer is arranged inside the material holding box and is electrically connected with a driving device. Air is blasted into the heating device by the air blower and is uniformly blown into the material holding box via air blowing holes in a sleeve tube after being heated by a heating wire, and materials are stirred by the stirrer, so that the materials can be heated uniformly and dried quickly without being affected in performance.
Description
Technical field
The present invention relates to a kind of blast drier, relate in particular to a kind of blast drier for dried granules or powder.
Technical background
Plastics role in life is more and more, and in the injection molding process of modifying plastics and plastic part, raw material has absorbed moisture content, if directly plastic product is heated, can cause material breakdown in plastic product, causes its performance and bad order.So need the raw material of these moisture absorptions to dry and can carry out next step processing before processing.Mainly with drying machine, pellet or powder are dried at present, drying machine is to be connected and composed by pipeline by a material box and a heater, heat is to carry it in material box by air blast air blast, and air inlet is at material box bottom center position, and air outlet is at material box top.Such drying machine is in real work, due to the heat part of just having scattered and disappeared before bringing material box into by air blast, material box is conventionally very high, thermal conduction rate is slower from bottom to top, also there is the passage of amount of heat, so can cause each temperature distributing disproportionation in material box, bottom half temperature is generally 3/4 of instrument settings (theoretical value), casing head temperature only has 1/2 of instrument settings (theoretical value).Due to the deficiency of temperature, cause hydraulic performance decline after Raw material processing, and cause finished product to have open defect, had a strong impact on the quality of plastic product.
Summary of the invention
The object of the invention is in order to overcome prior art defect, a kind of simple in structure, uniform blast drier of heat conduction is provided.
Technical scheme of the present invention is:
A blast drier, comprises material box and heater, and described heater is vertical at material box axis line inside place, and the bottom of heater is connected with the outlet air end of being located at the air blast of material box below; The inside of described material box is provided with stirring arm, and described stirring arm is electrically connected with drive unit.
Further, described heater comprises bobbin, and described barrel inner is provided with heating wire, evenly offers several gas holes on the sidewall of bobbin.
Described heater is electrically connected with controller.
The top of described material box is provided with charging aperture, bottom is provided with discharging opening; In the middle of the top of material box, offer annular distance.
The bottom of described material box is supported by support; Material box is cylindrical structure, and its bottom face is outer ellipse.
Described stirring arm is steel helical form.
Material box in the present invention is hollow circular cylinder, and upper surface is round plane, in the middle of it, offers annular distance one, and paddle is connected with outside drive unit by annular distance with the electric wire that is connected of drive unit, also has degassing function simultaneously.The lower surface of material box is the outer ellipse of certain radian, while being conducive to blowing, material in material box can be put totally.
Heater in the present invention consists of the bobbin heating wire inner with it, bobbin is iron, on its sidewall, be evenly distributed with some gas holes, air blast blasts heater inside by wind, after electric-heating-wire-heating, its hot blast can enter the inner space of material box equably by blowhole, be furnished with highdensity steel wire and prevent that drying material from leaking in heater in blowhole.
During use, from charging aperture, add and account for the materials such as the pellet of material box volume 70-80% or powder, baking temperature and the drying time of heater are set by controller according to material behavior.Start air blast, air is blasted to heater inside, after electric-heating-wire-heating, from bobbin, with the blowhole of steel wire, be blown into material box, the air being heated enters heat equably continuously each space of material box inside material is heated, and the material that makes to be positioned at the top and bottom of material box is heated basic identical.The inwall of material box is heated and also heat is fed back to material simultaneously.Then by drive unit, start stirring arm, slowly stir the material in material box, avoid powder or pellet to decompose because local temperature is too high.Gas after heat exchange is discharged from the annular distance on material box top.
Compared with prior art, the present invention has the following advantages:
1, the present invention is simple in structure, easy to operate;
2, because heater is to be vertical at material box axis line inside place, on its bobbin sidewall, evenly offer blowhole, the material that makes to be positioned at the top and bottom of material box is heated basic identical;
3,, because material box inside is provided with stirring arm, stirring material, makes that it is heated evenly, rate of drying is fast, and drying efficiency is high.
4, heater is electrically connected with controller, and baking temperature and the drying time of heater can be set according to properties of materials to be dried and water content, thereby when reaching dry, also avoids material to decompose because of excess Temperature.

Fig. 3 is the heater structure schematic diagram in the present invention.
In figure: 1-heater, 1-1 bobbin, 1-2 gas hole, 2-charging aperture, 3-material box, 4-air blast, 5-support, 6-discharging opening, 7-stirring arm, 8-controller, 9-drive unit, 10-annular distance.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
As shown in Figure 1, a kind of blast drier, comprises material box 3 and heater 1, and described heater 1 is vertical at material box 3 axis line inside places, and the bottom of heater 1 is connected with the outlet air end of being located at the air blast 4 of material box bottom; Heater 1 is electrically connected with and regulates temperature and the controller of drying time 8; The inside of described material box 3 is provided with steel helical form stirring arm 7, and described stirring arm 7 is electrically connected with drive unit 9.Material box 3; Material box 3 is cylindrical structure, and its bottom is supported by support 5; The top of material box 3 offers annular distance in the middle of being provided with charging aperture 2, top; Material box 3 bottoms are provided with discharging opening 6, bottom face is outer ellipse.
When dry, air blast blasts heater inside by air, after electric-heating-wire-heating, from bobbin, with the blowhole of steel wire, is blown into material box, and material in material box is carried out to homogeneous heating, and the material that makes to be positioned at the top and bottom of material box is heated basic identical.Then by drive unit, start stirring arm, slowly stir the material in material box, avoid powder or pellet to decompose because local temperature is too high.Gas after heat exchange is discharged from the annular distance on material box top.
