In the above-mentioned application document, through being provided with double-deck metal guipure, make chinese-medicinal material press from both sides in double-deck metal guipure, be favorable to the upset of chinese-medicinal material in the stoving process, make the stoving effect of chinese-medicinal material better. However, in the traditional Chinese medicine dryer, the hot air blower is arranged at the top of the drying box, and when the traditional Chinese medicine dryer is used for drying, the heat of the upper layer is larger, and the heat of the lower layer is smaller. Because the heat distribution in the stoving case is inhomogeneous, make double-deck metal mesh be heated inadequately in pressing from both sides the medicinal material transfer process, and then lead to the technical problem that medicinal material drying effect is not good. Therefore, a new solution is needed to solve the above problems.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a belt type dryer.
The above object of the present invention is achieved by the following technical solutions:
a belt dryer comprises a rack, wherein a slope conveying belt used for feeding is arranged at one end of the rack, a support is arranged outside the rack, a hot blast stove is mounted on the support, the hot blast stove is respectively connected with a burner used for emitting heat and a high-pressure fan used for blowing air into the hot blast stove, a plurality of air outlets used for exhausting air are formed in the side wall of the rack, at least two layers of conveying platforms are sequentially arranged in the rack along the vertical direction of the rack, each conveying platform comprises a conveying belt and a transmission structure for driving the conveying belt to convey, the conveying directions of the adjacent conveying platforms are opposite, the conveying platform at the bottommost layer extends out of one end, far away from the slope conveying belt, of the rack, an air exhaust box with a hollow inner part is mounted in an interlayer of each layer of the conveying belt, a plurality of air exhaust holes are formed in the top of the air exhaust box, and, the air inlet is connected with the hot blast stove through a hot air adjusting mechanism.
Through adopting above-mentioned technical scheme, belt dryer is at the during operation, and the slope conveyer belt conveys the medicinal material to the transfer platform of the top layer in the frame, and the transfer platform of the top layer passes to the transfer platform of next floor again, so circulate, arrange to the transfer platform of the bottom layer finally, finally spread the frame from the transfer platform of bottom layer. The medicinal material is at the in-process of each layer conveying platform conveying, and the combustor sends a large amount of heats and discharges into to the hot-blast furnace through burning fuel, and high pressure positive blower lets in strong wind towards the hot-blast furnace in, and strong wind fully heats in the hot-blast furnace and forms hot-blastly, and hot-blastly enters into each row of wind box by the air intake again through hot-blast adjustment mechanism in, discharges towards the medicinal material on the conveyer belt by the air exit on the case of airing exhaust at last, finally reaches the purpose of drying to the medicinal material on the conveyer belt. Through setting up the multilayer conveying platform in the frame and installing the exhaust case in every layer of conveyer belt intermediate layer, can carry out abundant drying process to the medicinal material, every layer of conveying platform all can receive solitary hot-blast processing, make hot-blast individual layer drive belt to in every layer of conveying platform carry out drying process, make the medicinal material be heated more fully, simultaneously, also make the medicinal material be heated more evenly, reduce hot-blast waste, make the stoving effect of medicinal material better.
