According to the invention, double-layer grinding and even three-layer grinding are realized by arranging the three grinding discs and the grinding ring 3, food waste is gradually ground, so that the grinding is more sufficient, the first grinding disc 4 and the second grinding disc 5 grind the waste grinding particles in a grinding disc-like manner through relative rotation, the fineness of the waste grinding particles is greatly improved, and the waste grinding particles are discharged in a liquid-like manner under the action of water flow, so that a sewer cannot be blocked.

The upper end surface of the second grinding disc 5 is a concave surface which inclines downwards from the peripheral edge to the center, so that the influence of centrifugal force generated when the second grinding disc 5 rotates on the garbage grinding particles is reduced, and the garbage grinding particles are smoothly gathered near the pore passage 51 to enter the operation interval of relative grinding of the first grinding disc 4 and the second grinding disc 5 for grinding. If the upper end surface of the second polishing disk 5 is a flat surface, the garbage abrasive grains entering from the operation section of the third polishing disk 6 may be gathered on the outer periphery of the upper end surface of the second polishing disk 5 by the centrifugal force, and may be difficult to enter the operation section where the first polishing disk 4 and the second polishing disk 5 are relatively polished.

Similarly, the depth of the first groove 41 and the second groove 52 becomes shallower from the inside to the outside, which helps the garbage abrasive grains to be sufficiently ground.

The plurality of pore channels 51 are arranged on the second grinding disc 5, compared with the situation that only one pore channel 51 is arranged in the middle part, the garbage grinding particles can enter the operation interval through different pore channels 51 without gathering near one pore channel 51 and entering the operation interval, the grinding efficiency is improved, the pore channels 51 are prevented from being blocked,

the diameter of each hole 51 is gradually increased from the outer peripheral edge of the second grinding disk 5 to the center, and this arrangement is favorable for more garbage grinding particles to enter the middle position of the operation interval along the hole 51 distributed in the middle part of the upper end face of the second grinding disk 5, so that the garbage grinding particles are gradually ground from the middle position to the outer periphery, and the grinding is more sufficient. The distance between adjacent portholes 51 is gradually reduced from the outer periphery of the second grinding disk 5 towards the center, also for a better fit with this concave surface.

grinding disks

4 and 5 are made of the same material, the axial height of the second grinding disk 5 is greater than that of the first grinding disk 4.

In another embodiment of the present invention, the upper end surface of the second grinding disk 5 is a concave surface which is inclined downwards from the peripheral edge to the center, the concave surface is a smooth transitional concave surface with a flat center, and the concave surface is provided with a material guiding chute for guiding the garbage to flow, the material guiding chute is a groove which extends from the center to the periphery, and the grooves extend from the vicinity of the central through hole to the outer peripheral edge of the upper end surface of the second grinding disk 5. The width of the guide chute at the outer peripheral edge is different from the width in the vicinity of the central through hole, that is, the width of the guide chute gradually increases from the outer peripheral center of the upper end surface of the second grinding disk 5. The material guide grooves are uniformly distributed along the circumferential direction of the second grinding disc 5. The baffle box guides the rubbish flow direction, can make rubbish abrasive particles get into the operation interval of first abrasive disc 4 and second abrasive disc 5 more smoothly and grind, improves grinding efficiency.

In another embodiment of the present invention, the lower end surface of the second polishing disk 5 is a concave surface inclined upward from the peripheral edge to the center, and an operating region for relative polishing between the concave surface of the second polishing disk 5 and the upper end surface of the first polishing disk 4 is formed. Compared with a horizontal end face, the concave face can accommodate more garbage grinding particles, and the gap between the upper end face of the first grinding disc 4 and the lower end face of the second grinding disc 5 is gradually reduced from the middle part of the concave face to the outer periphery of the concave face, so that the garbage grinding particles are ground to be fine enough and then discharged from a working interval in which the first grinding disc 4 and the second grinding disc 5 are relatively ground
