In combination with the above embodiment, the application principle and working process of the invention are as follows:
when the operation starts, cooling liquid is introduced from the liquid inlet 160 to cool the interior of the cylinder 100; then, starting the motor 201, and driving the motor 201 to drive the rotating shaft 206 of the feeding blade 205 to rotate through the speed reducer 202, so as to drive the middle grinding wheel 218 to rotate;
material is fed from the feed port 204, pushed down by the feed blade 205, and dispersed around by the dispersion plate 211 and into the first grinding zone. Under the rotation of the middle grinding wheel 218, the material is ground from top to bottom through the first grinding zone and falls down over the upper limiting plate 132, is sufficiently cooled by the cooling liquid between the upper limiting plate 132 and the lower limiting plate 133, and then comes to the second grinding zone under the action of the material guiding plate 2181.
After the material passes below the second grinding zone, the grinding ribs on the middle grinding wheel 218 and the small grinding wheel 212 and the pushing of the rear material gradually rise, and pass through the outside of the filter cartridge 213, then pass through the filter cartridge 213 and enter the small grinding wheel 212, and finally are discharged from the discharge pipe 215.
The middle grinding wheel 218 drives the material to rotate so as to grind the material, the material also gives the corresponding rotating acting force to the small grinding wheel 212 in the grinding process, when the grinding resistance of the second grinding area is larger, the rotating acting force received by the small grinding wheel 212 is larger, the acting force drives the small grinding wheel 212 to rotate, and the small grinding wheel 212 rises under the action of spiral transmission in the rotating process, so that the grinding stroke of the second grinding area is increased, and the grinding effect is increased; when the grinding resistance of the second grinding area is reduced, the first elastic member 304 resets to drive the small grinding wheel 212 to move downward, thereby reducing the stroke of the second grinding area and increasing the use area of the filter screen.
Some materials that can't pass cartridge filter 213 can be piled up the top by new material, when the material of cartridge filter 213 outside piles up more, cartridge filter 213 is blocked and is rotated under the drive of material, and then makes little grinding wheel 212 rotate thereupon, moves up when little grinding wheel 212 rotates and grinds the partial material secondary that the top was piled up, guarantees the grinding effect.
The second grinding section has a variable grinding resistance so that the wiper 307 scrapes off the material blocked outside the filter cartridge 213 during the up-and-down movement of the small grinding wheel 212.
After the work is finished, stopping feeding, waiting for all the internal materials to be ground and discharged, and then turning off the motor 201 and turning off the cooling system.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
