[0002] Grain processing refers to the business activities of converting raw grain into semi-finished grain or finished grain, or converting semi-finished grain into finished grain.

[0003] In the process of grain processing, the grain raw materials need to be transported by a conveying mechanism. In the prior art, most of the conveying mechanisms are not able to clean the dust well because the grains are not processed and are mixed with a lot of dust. Meanwhile, the conveying mechanisms with dust removal function have a simple dust removal structure, which only separates the dust from the grains. Most of the dust is raised into the air, causing extremely serious pollution and easily causing damage to the health of workers in the processing workshop. Therefore, it is necessary to design a dust removal device for grain processing to address the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 A dust removal device for grain processing comprises a base plate 1, a plurality of pulleys 2 are fixedly mounted on the bottom wall of the base plate 1, a dust removal box 4 is fixedly connected to the upper end surface of the base plate 1 through a lifting mechanism, the lifting mechanism comprises a scissor-type lifting frame 3 fixedly mounted on the upper end surface of the base plate 1, the telescopic end of the scissor-type lifting frame 3 is fixedly connected to the outer bottom wall of the dust removal box 4, two stabilizing plates 6 are slidably mounted on the upper end surface of the base plate 1 through a stabilizing mechanism, the stabilizing mechanism comprises a stabilizing rod 5 fixedly mounted on the upper end surface of the base plate 1, the stabilizing rod 5 slides through the stabilizing plate 6, a limiting plate 7 cooperating with the stabilizing plate 6 is fixedly mounted on the end of the stabilizing rod 5, the limiting plate 7 can limit the stabilizing plate 6 to prevent it from detaching from the outer wall of the stabilizing rod 5, a filling port is provided on the upper end surface of the dust removal box 4, and a sealing plug 8 is threadedly mounted on the inner wall of the filling port.

[0023] The ends of the two stabilizing plates 6 are fixedly connected to the outer wall of the dust removal box 4, and the inner bottom wall of the dust removal box 4 is inclined. The inclined inner bottom wall of the dust removal box 4 is conducive to the smoother discharge of sewage mixed with dust from the sewage pipe 9, thereby preventing a large amount of dust from being deposited in the inner bottom wall of the dust removal box 4 and unable to be discharged. The outer wall of the dust removal box 4 is fixedly installed with a sewage pipe 9 connected to the interior, and the upper end surface of the dust removal box 4 is fixedly installed with an induced draft fan 10, and the outlet pipe of the induced draft fan 10 penetrates into the dust removal box 4. The outer wall of the inlet pipe of the induced draft fan 10 is fixedly installed with a dust hood 11, and a filter plate 12 is fixedly installed inside the dust removal box 11. A reciprocating screw 13 is rotatably installed inside the dust removal box 11, and a motor 14 connected to the reciprocating screw 13 is fixedly installed on the outer wall of the dust removal box 11.

[0024] A screw sleeve 16 is threadedly installed on the outer wall of the reciprocating screw 13 through a limiting mechanism. The limiting mechanism includes a limiting rod 15 fixedly installed inside the dust hood 11. The limiting rod 15 slides through the screw sleeve 16. The limiting rod 15 can limit the screw sleeve 16 so that the screw sleeve 16 can only move axially along the outer wall of the reciprocating screw 13. A brush plate 17 is fixedly installed on the upper end surface of the screw sleeve 16. A purification channel 18 connected to the interior is fixedly installed on the upper end surface of the dust removal box 4. Two purification plates 19 are slidably installed on the outer wall of the purification channel 18 through a sliding opening. Both purification plates 19 are made of activated carbon material. Activated carbon is a porous substance with many micropores and mesopores. The diameters of these small pores can range from a few nanometers to hundreds of nanometers. When harmful gases or chemicals come into contact with activated carbon, they will be adsorbed by the activated carbon through physical adsorption and chemical adsorption.

[0025] When the utility model is used, the bottom plate 1 can be conveniently moved by the cooperation of a plurality of pulleys 2, thereby driving the dust hood 11 to move above the conveying mechanism, and then the scissor lift 3 can drive the dust box 4 to move up and down, thereby conveniently adjusting the distance between the dust hood 11 and the conveying mechanism, and the dust box 4 can drive the stabilizing plate 6 to slide on the outer wall of the stabilizing rod 5 during the up and down movement of the dust box 4, thereby increasing the stability of the dust box 4 when it moves up and down, and before dust removal, the sealing plug 8 can be rotated to release the seal of the filling port, and then the dust can be filled into the dust box through the filling port. Dust removal water is filled in the box 4, and the outlet pipe of the induced draft fan 10 is submerged by the dust removal water. Then, the sealing plug 8 can be rotated to seal the filling port. When the dust is processed, the induced draft fan 10 can absorb the dust through the cooperation of its inlet pipe and the dust hood 11. The filter plate 12 can prevent the food from being sucked into the induced draft fan 10, and avoid the induced draft fan 10 from being blocked. The sucked air can be discharged into the dust removal water in the dust removal box 4 through the outlet pipe of the induced draft fan 10. The dust removal water can separate and settle the dust in the air, so as to achieve the purpose of dust removal.

[0026] The air after dust removal can be discharged through the purification channel 18, and when the air circulates inside the purification channel 18, the two purification plates 19 can absorb the odor in the air, thereby purifying the air. When the bottom wall of the filter plate 12 absorbs grain, the motor 14 can drive the reciprocating screw 13 to rotate. When the reciprocating screw 13 rotates, it can drive the screw sleeve 16 to move by cooperating with the limit rod 15. The screw sleeve 16 then drives the brush plate 17 to move to clean the bottom wall of the filter plate 12. This can avoid a large amount of grain from affecting the circulation effect of the filter plate 12, and prevent the reduction of the efficiency of absorbing dust in the air. After long-term use, the dust removal water can be discharged from the inside of the dust removal box 4 through the drain pipe 9.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
