The third grinding disc 6 and the second grinding disc 5 share the same grinding ring 3, that is, the horizontal plane where the third grinding disc 6 is located intersects with the grinding ring 3 at the middle upper end of the grinding ring 3, the horizontal plane where the second grinding disc 5 is located intersects with the grinding ring 3 at the lower end of the grinding ring 3, and preferably, the lower end face of the grinding ring 3 and the outer edge of the lower end face of the second grinding disc 5 are located at the same horizontal plane. The third grinding disc 6 and the grinding ring 3 form a working interval of the third grinding disc 6, the third grinding disc 6 and the grinding ring 3 are mutually matched with each other in a relative rotation mode to perform preliminary treatment on the garbage entering the grinding cavity 2 from the water storage tank 1, and the second grinding disc 5 and the grinding ring 3 are mutually matched with each other in a relative rotation mode to further treat the garbage grinding particles flowing out of the working interval of the third grinding disc 6.

The peripheral wall of the grinding ring 3 is provided with through holes penetrating through the peripheral wall in the radial direction, and compared with other parts of the grinding ring 3, the through holes are equivalent to cutter teeth arranged on the grinding ring 3, so that garbage thrown onto the grinding ring can be cut. Alternatively, the grinding ring 3 is provided with no through holes, and the inner wall of the grinding ring 3 is uniformly provided with bulges or spiral threads, so that the garbage can be further ground by the bulges or the spiral threads.

The garbage enters the working space of the third grinding disc 6 through the water storage tank 1 to grind into garbage grinding particles with the diameter of 4-5mm, under the action of gravity and centrifugal force, along with water flow, the garbage grinding particles reach the upper end face of the second grinding disc 5 through water leakage holes on the third grinding disc 6 or gaps formed by the inner wall of the grinding ring 3 and the outer peripheral edge of the third grinding disc 6, part of the garbage grinding particles are mutually matched and ground by the second grinding disc 5 and the grinding ring 3, enter the working space of the first grinding disc 4 and the second grinding disc 5 through the pore canal 51 on the second grinding disc 5 to further grind, or directly flow out from the gaps formed between the outer peripheral edge of the second grinding disc 5 and the inner wall of the grinding ring 3, part of the garbage grinding particles directly enter the working space of the first grinding disc 4 and the second grinding disc 5 through the pore canal 51 on the second grinding disc 5, and liquid-like slurry is formed from the gaps formed between the outer peripheral edge of the first grinding disc 4 and the inner wall of the grinding cavity 2 to be discharged into a sewer.

The upper end surface of the second grinding disc 5 is a concave surface which is inclined 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 converged near the pore canal 51 so as to enter an operation interval where the first grinding disc 4 and the second grinding disc 5 are oppositely ground for grinding. If the upper end surface of the second polishing disc 5 is flat, the dust polishing particles entering from the working section of the third polishing disc 6 may be gathered on the outer periphery of the upper end surface of the second polishing disc 5 by the centrifugal force, so that the dust polishing particles are difficult to enter the working section where the first polishing disc 4 and the second polishing disc 5 are relatively polished.

Grooves are uniformly formed in the lower end surface of the second grinding disc 5 to serve as second grooves 52 for guiding the garbage grinding particles to flow from the middle to the outer periphery, the garbage grinding particles are ground gradually, the width of the second grooves 52 gradually narrows from the center of the lower end surface of the second grinding disc to the outer periphery, the speed of the garbage grinding particles flowing from the center to the outer periphery is forced to be reduced, the garbage grinding particles can smoothly flow from the center to the outer periphery only after gradually becoming smaller, and therefore the garbage grinding particles are fully ground from the center to the outer periphery. Similarly, the depth of the first grooves 41 and the second grooves 52 are reduced from inside to outside, which helps the garbage grinding particles to be sufficiently ground.

The second grinding disc 5 is provided with a plurality of pore canals 51, so that the garbage grinding particles can enter the operation interval through different pore canals 51 without converging near one pore canal 51 and then entering the operation interval, the grinding efficiency is improved and the pore canals 51 are prevented from being blocked,

The hole diameters of the hole channels 51 gradually become larger from the peripheral edge to the center of the second grinding disc 5, and the arrangement is favorable for more garbage grinding particles to enter the middle position of the operation interval along the hole channels 51 distributed at the middle part of the upper end surface of the second grinding disc 5, so that the garbage grinding particles are gradually ground from the middle position to the periphery, and the grinding is more sufficient. The distance between adjacent channels 51 becomes smaller from the outer circumferential center of the second grinding disc 5 also for better cooperation with this concave surface.

The grinding ring 3 is a grinding ring shared by the second grinding disc 5 and the third grinding disc 6, so that the second grinding disc 5 and the grinding ring 3 can be matched with each other to further grind the garbage grinding particles formed after the third grinding disc 6 and the grinding ring 3 are matched with each other, namely, the second grinding disc 5 and the grinding ring 3 form another operation interval, and the grinding efficiency is improved. The diameter of the second grinding disc 5 is larger than that of the third grinding disc 6, so that a gap formed between the outer peripheral edge of the second grinding disc 5 and the inner wall of the grinding ring 3 is smaller than that formed between the outer peripheral edge of the third grinding disc 6 and the inner wall of the grinding ring 3, and the garbage grinding particles passing through the gap formed between the outer peripheral edge of the third grinding disc 6 and the inner wall of the grinding ring 3 cannot be directly discharged from the gap formed between the outer peripheral edge of the second grinding disc 5 and the inner wall of the grinding ring 3, so that the garbage grinding particles after grinding of the second grinding disc 5 and the grinding ring 3 can be discharged only slightly, and the garbage grinding quality is ensured.

In another embodiment of the present invention, the second grinding disc 5 is connected to the driving shaft 71 by a sliding key, and the second grinding disc 5 is movable in the axial direction of the driving shaft 71, and in this arrangement, if the second grinding disc 5 located above is heavier than the first grinding disc 4 located below, a better grinding effect can be produced, and therefore, in the case where the first grinding disc 4 and the second grinding disc 5 are made of the same material, the axial height of the second grinding disc 5 is greater than that of the first grinding disc 4.

In another embodiment of the invention, the upper end surface of the second grinding disc 5 is a concave surface inclined downwards from the peripheral edge to the center, the concave surface is a flat concave surface with a smooth transition center, a guide groove for guiding the garbage flow direction is arranged on the concave surface, the guide groove is a groove extending from the center to the periphery, and the grooves extend from the vicinity of the central through hole to the peripheral edge of the upper end surface of the second grinding disc 5. The width of the guide groove at the outer peripheral edge is not the same as that near the central through hole, i.e., the width of the guide groove gradually increases from the outer periphery to the center of the upper end surface of the second grinding disc 5. The guide grooves are uniformly distributed along the circumferential direction of the second grinding disc 5. The guide chute guides the garbage to flow, so that garbage grinding particles can smoothly enter the operation interval of the first grinding disc 4 and the second grinding disc 5 to grind, and the grinding efficiency is improved.

In another embodiment of the present invention, the lower end surface of the second polishing disc 5 is a concave surface inclined upwards from the peripheral edge to the center, and an operation area for the two polishing discs to polish is formed between the concave surface of the second polishing disc 5 and the upper end surface of the first polishing disc 4. The concave surface is arranged to accommodate more garbage grinding particles relative to the horizontal end surface, on the one hand, the concave surface can enable the gap between the upper end surface of the first grinding disc 4 and the lower end surface of the second grinding disc 5 to gradually decrease from the middle part of the concave surface to the periphery, so that the garbage grinding particles are ground to be small enough and then discharged from the operation interval where the first grinding disc 4 and the second grinding disc 5 are oppositely ground

As shown in fig. 9, the third grinding disc 6 is provided with at least two kinds of grinding members for grinding garbage, the two kinds of grinding members are any two kinds of grinding hammers, convex hulls and cutting knives, and any two kinds of grinding members are two, and are alternately arranged at intervals in sequence in the circumferential direction.

The first grinding hammers 61 are adjacent to the first convex hulls 63, the first grinding hammers 61 are located closer to the first convex hulls 63, and are located farther from the second convex hulls 64, and the total area of the adjacent first grinding hammers 61 and first convex hulls 63 occupying the area on the upper end face of the third grinding disc 6 is smaller than the area of one quarter of the upper end face of the third grinding disc 6, and the second grinding hammers 62 and second convex hulls 64 are also. The first grinding hammer 61 is relatively close to the first convex hull 63, and the first grinding hammer 61 and the first convex hull 63 are matched with each other to hammer the garbage repeatedly, meanwhile, as the first grinding hammer 61 and the second grinding hammer 62 can rotate freely, hard objects can be avoided when the first grinding hammer 61 and the second grinding hammer 62 encounter hard objects, the first convex hull 63 and the second convex hull 64 which are respectively close to the first grinding hammer 61 and the second grinding hammer 62 can hammer the hard objects, and the grinding efficiency of the first grinding device on the food garbage is improved.

The first convex hull 63 is composed of a central bulge and three peripheral bulges arranged around the central bulge, the three peripheral bulges are respectively connected with the central bulge, the bottom surfaces of the central bulge and the three peripheral bulges are respectively connected with the upper end surface of the third grinding disc 6, the highest point of each of the three peripheral bulges is lower than the highest point of the central bulge, the highest points of the three peripheral bulges are respectively positioned at the connection positions with the central bulge, the surfaces of the central bulge and the three peripheral bulges are arc-shaped surfaces, and the central bulge and the three peripheral bulges are part of a sphere when visually seen.
