Description
Technical field
The present invention relates to a kind of pair of circulation air path infrared drying machine.
Background technology
Existing drying oven air circulating system is one-sided air draught, the mode of opposite side blowing, because room blasting and wind suction is not in the same side, cause blowing up bellows blowing amount and lower air-suction trunk suction air volume everywhere everywhere inhomogeneous, because there is the energy loss problem in hot blast in transmission course, difference can appear in the blowing temperature of the drying tunnel left and right sides simultaneously, thereby the inconsistent phenomenon of the temperature that the drying tunnel both sides occur, and drying tunnel is wider, and this phenomenon is more obvious, affects the quality of the material that is dried.Adopt the bilateral circulation air path, can reduce the temperature difference in the drying tunnel, improve the quality of the material that is dried.
Summary of the invention
The invention provides a kind of pair of circulation air path infrared drying machine, it not only can reduce the impact of the energy loss of hot blast in cyclic process on the blowing temperature, and so that the interior Temperature Distribution of drying oven is more even.
The present invention has adopted following technical scheme: a kind of pair of circulation air path infrared drying machine, it comprises cabinet (1), top at cabinet is provided with loam cake, heat-insulation layer in loam cake, being provided with, in cabinet, be provided with the drying tunnel air circulating system, described drying tunnel air circulating system comprises circulating fan, left blowing air channel, left air draught air channel, right blowing air channel, right air draught air channel, blowing up bellows and blowing down bellows, the air outlet of circulating fan is connected with the import in left blowing air channel and the import in right blowing air channel respectively, the import in left blowing air channel is communicated with the left side of blowing up bellows by left air draught air channel, the import in right blowing air channel is communicated with the right side of blowing up bellows by right air draught air channel, the blowing down bellows are positioned at the bottom of blowing up bellows, between blowing up bellows and blowing down bellows, be provided with heating tube, the air outlet of blowing up bellows bottom is relative with heating tube, be provided with lower thermal insulation layer at the blowing down bellows, around lower thermal insulation layer, be distributed with left circulation air path and right circulation air path, top at the blowing down bellows is provided with air inlet, air inlet is relative with heating tube, and the left side of air inlet and right side are connected with left circulation air path and right circulation air path respectively.
Described heating tube is set to infrared radiant tube.
The present invention has following beneficial effect: in infrared drying, because the continuous evaporation endothermic of surface moisture in the material that is dried, material surface temperature is reduced, cause material internal temperature specific surface temperature high, make like this thermal diffusion direction of material by outward interior.Simultaneously, owing to existing the gradation of moisture to cause that moisture moves in the material, always spread to the less outside of moisture by the more inside of moisture.So, the wet diffusion of material internal moisture is consistent with the thermal diffusion direction, thereby also just accelerated the process of moisture diffusion, also namely accelerated dry process, the present invention is provided with the radiation of UV radiation device and comes dry, the every joint drying tunnel of this dryer all adopts two circulation air path modes, the drying tunnel air circulating system is by circulating fan, left blowing air channel, left air draught air channel, right blowing air channel, right air draught air channel, the blowing up bellows, the parts such as lower air-suction trunk form, circulating fan is with the air channel of drying about air draught air channel, the left and right sides blows to of the hot-air in the stove, again through about the blowing drying tunnel enter upper bellows, then blow out downwards from upper bellows.Because adopt the both sides binary cycle system, blowing amount and suction air volume more evenly distribute, reduced the impact of the energy loss of hot blast in cyclic process on the blowing temperature.So that Temperature Distribution is more even in the drying oven.
