Description

Technical Field

[0001] The utility model relates to the technical field of grain drying, in particular to a bottom dehumidification device for a drying machine. Background Art

[0002] Grain refers to the general term for various plant seeds used in cooking food, and can also be generally referred to as "cereals". Grain crops are rich in nutrients, mainly protein, vitamins, dietary fiber, fat, starch, etc.

[0003] The dehumidification device transfers heat energy directly to the grain through heat conduction during the drying process, causing the moisture in the grain to evaporate continuously in the cylinder. At the same time, it takes away 9 types of Fusarium and vomitoxin, which are common soil diseases in the world, making us eat healthily and reducing the incidence of gastrointestinal diseases and cancer. Therefore, the drying and dehumidification process is an indispensable step in the grain processing process.

[0004] The existing dryer directly loses hot air during drying, which is quite wasteful. In addition, the dehumidification efficiency of the dryer is low, and the dehumidification effect in the grain is not good.

[0005] Secondly, due to the simple structural layout of the grain, the grain inside is dried and heated unevenly, and the dehumidification efficiency is poor, which urgently needs to be developed. Utility Model Content

[0006] The purpose of the utility model is to provide a bottom dehumidification device for a drying machine to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bottom dehumidification device for a dryer, comprising a grain drying machine box, a rotating grain storage cylinder, a hygroscopic cotton layer and a hot air blower, the bottom of the grain drying machine box is connected to a rotating drive mechanism, the top of the rotating drive mechanism is connected to a transmission rod, the top of the transmission rod is connected to a rotating grain storage cylinder, the bottoms of both sides of the rotating grain storage cylinder are symmetrically connected to limited rotating rods, the two sides of the grain drying machine box are symmetrically connected to limited grooves, the limited rotating rods are slidably connected to the limited grooves, the front side, rear side and both sides of the rotating grain storage cylinder are connected to drying and dehumidification operation ports, and the inner surface of the rotating grain storage cylinder is adhered to a hygroscopic cotton layer.

[0008] Preferably, hot air blowers are symmetrically installed on both sides of the grain drying machine box.

[0010] Preferably, corresponding openings are provided inside the moisture-absorbing cotton layer, and the corresponding openings correspond to the positions of the drying and dehumidification operation openings.

[0011] Preferably, an air duct is connected to the top of the hot air blower.

[0012] Preferably, positioning blocks are symmetrically connected to both ends of the bottom of the dustproof net, and positioning grooves are symmetrically connected to the surface of the top of the grain drying machine box.

[0013] Preferably, two sliding fixing plug-ins are symmetrically arranged inside the positioning block, the sliding fixing plug-ins are movably arranged inside the positioning block, and the two sliding fixing plug-ins are connected by a spring.

[0014] Preferably, the positioning groove and the positioning block are arranged in a position corresponding to each other, and fixing slots are symmetrically connected to both sides of the positioning groove.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) The bottom dehumidification device of the dryer drives the grain in the rotary grain storage cylinder to perform rotary drying by using the rotary drive mechanism, the transmission rod, the limit rotary rod and the limit groove, so that the material is dried more evenly. Then, a part of the hot air is circulated and transported to the hot air blower through the air guide pipe through the hot air blower to reduce the energy consumption of the hot air blower for heating the air. The other part of the hot air can be discharged through the vent to make the air circulate and improve the drying efficiency of the grain.

[0017] (2) The bottom dehumidification device of the dryer can remove a certain amount of moisture from the grain during drying by setting a moisture-absorbing cotton layer, thereby increasing the drying speed by 20%. The corresponding port is set correspondingly to the position of the drying and dehumidification operation port. The moisture-absorbing cotton layer is subsequently bonded to the inner wall of the rotary grain storage cylinder by gluing, which is convenient for subsequent direct replacement.

[0018] (3) The bottom dehumidification device of the dryer can prevent the circulating air from dust by setting up a dust-proof net to prevent dust from contacting the grain. The dust-proof net is connected to the preset positioning slot and the inner fixed slot by the coordinated use of the fixed slot, the sliding fixed plug-in and the spring, which makes it convenient to remove the dust-proof net for cleaning or replacement at a later time, thereby improving the dust-proof effect.
