[0021] Working principle:

[0022] The pretreatment box 1 is connected to a wet material processing device 3 above. The material agglomerated due to moisture falls into the material box 36 through the conveying funnel. A screw shaft 32 is provided in the material box 36. The screw shaft 32 is fixedly connected to the conveying motor 4 to keep the conveying motor 4 driving the screw shaft to feed the material at a constant slow speed. The lower end of the material box 36 is fixedly connected to a heating plate 9. The heating plate 9 transfers heat to the material box 36 to help dry the moisture agglomerated material conveyed on the screw shaft 32. The material then falls into the wet transport plate through the wet feed port, and the pressure agglomerated material falls into the dry transport plate through the dry feed port. The two materials fall into the grinding trough 14 as the wet transport plate and the dry transport plate tilt.

[0023] The grinding rod 5 is fixedly connected to the grinding teeth 15 distributed in a circumferential manner. When the grinding motor 4 rotates, the grinding rod 5 squeezes the block materials in the solid raw material against the side wall of the grinding groove 14. The grinding teeth 15 collide with the plate agglomerates and break them, which is convenient for subsequent grinding. The arc surface of the lower end of the grinding rod 5 contacts the filter port. As it rotates, friction and grinding are carried out, and the ground materials are filtered out through the filter port and fall into the discharge plate 13.

[0024] The exhaust fan 71 can be controlled by a control switch. When the exhaust fan 71 is working, an air pressure difference is formed on both sides, so that the dust waste falling from the discharge plate 3 when the pre-treatment box 1 is working is extracted into the box body 74 through the exhaust hole 18, and is adsorbed and filtered by the primary filter plate 72 and the secondary filter plate 73. Then, under the action of the air pressure difference, it is discharged from the porous exhaust port on the right side of the box body, so that the dust-rich air is purified and the spread of dust is effectively prevented;

[0025] The purified material flows out of the pretreatment box 1 through the discharge port 6 .
