Referring to fig. 1, a grinding apparatus according to an embodiment of the present invention includes a body 100, a feeding portion 200, a discharging portion 300, a first feeding mechanism 400, and a second feeding mechanism 500. The body 100 is driven by the driving device 710 to rotate, and the body 100 includes a first rotating shaft 110, a second rotating shaft 120 and a cavity 130, and a grinding member 140 for grinding a material is disposed in the cavity 130; the feeding part 200 is coaxially arranged with the body 100, the feeding part 200 comprises a feeding hole 210 arranged on the feeding part 200, and the feeding part 200 is communicated with the first rotating shaft 110; the discharging part 300 is coaxially arranged with the body 100, the discharging part 300 comprises a discharging port 310 positioned on the discharging part 300, and the discharging part 300 is communicated with the second rotating shaft 120; the first feeding mechanism 400 is positioned inside the feeding part 200 and pushes the material from the feeding hole 210 into the body 100; the second feeding mechanism 500 is located inside the second rotating shaft 120, and pushes the material from the body 100 to the discharging portion 300.

The first rotating shaft 110 and the second rotating shaft 120 are respectively located at two axial sides, i.e. left and right sides, of the body 100, the first rotating shaft 110 and the second rotating shaft 120 are hollow shafts, and the body 100 is supported by the first rotating shaft 110 and the second rotating shaft 120 and is driven to rotate around the first rotating shaft 110 and the second rotating shaft 12. The feeding portion 200 is disposed at the left side of the first rotating shaft 110, and may be disposed in a straight tubular structure, such that the inner circumferential surface of the feeding portion is matched with the outer circumferential surface of the first rotating shaft 110, and the right end of the feeding portion is partially sleeved in the first rotating shaft 110 and is coaxial with the first rotating shaft 110.

The discharging part 300 is disposed at the right side of the second rotating shaft 120, the left end of the discharging part partially covers the outer circumferential surface of the second rotating shaft 120, the discharging part 300 may be in an L-shaped tube shape, one part of the discharging part is disposed coaxially with the second rotating shaft 120, the other part of the discharging part is perpendicular to the axis of the second rotating shaft 120, and the discharging hole 310 is disposed at the lower side of the perpendicular part, so as to discharge the ground material. The feeding portion 200 and the discharging portion 300 can be kept stable while the material is conveyed, and the material such as garbage is continuously fed into the body 100.

The first feeding mechanism 400 is located inside the feeding portion 200, the first feeding mechanism 400 can push the material into the body 100 through the first rotating shaft 110 from left to right, the second feeding mechanism 500 is arranged in the second rotating shaft 120, and the second feeding mechanism 500 can push the ground material into the discharging portion 300 from left to right. Due to the arrangement of the first feeding mechanism 400, after the material is input into the feeding portion 200 from the feeding hole 210, the first feeding mechanism 400 pushes the material into the rotating body 100, and due to the arrangement of the grinding member 140 in the body 100, the grinding member 140 is thrown and falls down along with the rotating body 100, and the material is continuously ground, thereby completing the grinding of the material. Generally, in the process of grinding garbage, in order to flush solid garbage into the body 100, clear water is added during feeding to increase the flowability of the solid garbage, and the first feeding mechanism 400 is arranged in the feeding part 200, so that a large amount of water is not required to be added during feeding to dilute and flush the solid garbage, and the garbage can be rapidly input into the body 100, so that the problem of poor flowability of the solid garbage is effectively solved, further, the problem of low solid content of the garbage in the body 100 is improved, and the grinding efficiency is improved. And set up second feeding mechanism 500 in second pivot 120, can in time discharge body 100 with become mobile material after grinding, improve the solid rate in the body 100, guarantee that the high efficiency of grinding process goes on. The first feeding mechanism 400 and the second feeding mechanism 500 may be screw pushers, or mechanical pushers such as piston pushers. In some embodiments, for continuous feeding of material, an auger is used to convey the material by rotation of the helical blade.

In order to fix the grinding device and support the grinding device to rotate, the grinding device further comprises a base 700, a driving device 710 for driving the body 100 to rotate and an adjusting motor for adjusting the screw pusher are fixed on the base 700, and a mounting portion 720 is arranged on the base 700 and used for supporting the first rotating shaft 110 and the second rotating shaft 120, the mounting portion 720 can be a bearing seat, the first rotating shaft 110 and the second rotating shaft 120 are respectively connected to the mounting portion 720 through bearings, and the body 100 can be ensured to be stable through mutual matching with the bearings, so that the body 100 rotates under the support of the mounting portion 720.

With continued reference to fig. 1, in some embodiments, in order to quickly and thoroughly feed the material into the body 100, the material pushing end (right end) of the first feeding mechanism 400 extends into the discharging end (right end) of the first rotating shaft 110. The term "discharge end" as used herein means an end portion for transferring a material from an upstream member to a downstream member, and the term "pusher end" means an end portion of a feeding mechanism located in a discharge direction. Because the right end of the first rotating shaft 110 is connected with the left side of the cavity 130, the first feeding mechanism 400 can directly push the material into the cavity 130 for grinding, and the material is prevented from being left in the first rotating shaft 110 in the material pushing process, so that the grinding is not thorough. Specifically, the right end of the first feeding mechanism 400 is flush with the right end of the first rotating shaft 110.

Referring to fig. 1, in some embodiments, in order to prevent the ground material from being incompletely output, the second feeding mechanism 500 may be configured such that a material pushing end (right end) thereof can extend to a material discharging end (right end) of the second rotating shaft 120, that is, an axial length of the second feeding mechanism 500 is the same as an axial length of the second rotating shaft 120, and the second feeding mechanism 500 extends throughout the second rotating shaft 120, so that the ground material flowing out of the cavity 130 can be completely output to the material outlet 310 through the second feeding mechanism 500.

In some embodiments, in order to prevent the first rotating shaft 110 and the second rotating shaft 120 from rubbing against the feeding portion 200 and the discharging portion 300 during the rotation of the body 100, an inner circumferential surface of the first rotating shaft 110 and an outer circumferential surface of the feeding portion 200 are not in contact with each other, and a gap is provided, and it is conceivable that an inner circumferential surface of the discharging portion 300 and an outer circumferential surface of the second rotating shaft 120 may be disposed not in contact with each other, that is, a gap is provided. When the feeding portion 200 is sleeved in the first rotating shaft 110, the feeding portion and the first rotating shaft 110 are not in mutual contact, and a certain distance is kept, so that during the rotation of the body 100, friction force is not generated between the inner circumferential surface of the feeding portion 200 and the outer circumferential surface of the first rotating shaft 110, and the phenomenon that the feeding portion 200 and the first rotating shaft 110 are too fast aged and damaged is avoided, and further, the overall working efficiency of the grinding device can be improved. The advantage of providing a gap between the discharging part 300 and the second rotating shaft 120 is the same as the advantage of providing a gap between the feeding part 200 and the first rotating shaft 110, and thus, the description thereof is omitted.

Referring to fig. 1 and 2, in some embodiments, since there is a gap between the first rotating shaft 110 and the feeding portion 200, in order to prevent the material from leaking during the conveying process, a first sealing structure 600 is disposed between the first rotating shaft 110 and the feeding portion 200, and the first sealing structure 600 may be a mechanical seal or a packing seal. It is conceivable that the same applies to the discharging part 300 and the second rotating shaft 120, and the second rotating shaft 120 is fitted inside the discharging part 300 with a gap therebetween, and therefore, in order to prevent the ground material, such as slurry, from leaking to the outside, a second sealing structure 630 is provided at the junction of the discharging part 300 and the second rotating shaft 120. Specifically, the first and second sealing structures 600 and 630 include a sealing ring 610 and a sealing pressure plate 620. For example, the sealing ring 610 is fitted over the left end surface of the first rotating shaft 110, the sealing pressing plate 620 is fitted over the outer side of the sealing ring 610, and the sealing pressing plate 620 firmly presses the sealing ring 610 between the first rotating shaft 110 and the feeding unit 200, thereby preventing the sealing ring 610 from being separated and isolating a gap therebetween, thereby preventing garbage from leaking to the outside and polluting the environment. Similarly, a seal ring 610 and a seal pressing plate 620 may be provided between the second rotating shaft 120 and the discharging part 300. The sealing ring 610 is disposed on the left end surface of the discharging part 300, and a sealing pressing plate 620 is sleeved on the outer side of the sealing ring 610, thereby completing the sealing of the gap between the discharging part 300 and the second rotating shaft 120.

Referring to fig. 1 and 4, in some embodiments, in order to isolate the grinding noise of the grinding element 140, the inner wall of the cavity 130 is covered with a buffer 150, and the buffer 150 is tightly attached to the inner wall and covers the whole inner wall, so as to reduce the noise generated when the grinding element 140 or the material touches the inner wall, and since the buffer 150 is arranged on the inner wall, part of the noise can be absorbed, and the volume of the outward transmission is reduced. The buffer 150 may be made of a flexible material such as rubber, and can be tightly attached to the inner wall, and has a certain noise reduction effect. In order to continuously stir and turn the material during the rotation process, the buffer 150 is provided with a plurality of protrusions 151 in a direction towards the inside of the cavity 130. The shape of the protrusion 151 may be a convex ridge axially distributed along the cavity 130, or a convex ridge uniformly distributed on the surface of the buffer 150, as long as the material can be repeatedly stirred, so that the material can be repeatedly turned.

Referring to fig. 1 and 4, in some embodiments, in order to prevent the grinding member 140 from escaping from the cavity and simultaneously discharge the ground material from the cavity 130, a baffle 160 is disposed on a side of the cavity 130 close to the second rotating shaft 120, i.e., a right side of the cavity 130, a plurality of through holes 161 are disposed on the baffle 160, and a width of the through holes 161 should be smaller than a diameter of the grinding member 140, so as to block the grinding member 140 in the cavity 130 and prevent the grinding member 140 from escaping from the cavity 130 during grinding. The through holes 161 may be strip-shaped through holes 161 extending in the radial direction of the baffle 160, or may be annular through holes 161 spaced in the radial direction of the baffle 160. Ground material, such as refuse slurry, can flow out of the chamber 130 through the annular opening 161. A small amount of incompletely ground waste, such as plastic bags, cloth strips, etc., may be present in the ground waste slurry and may flow out through the through-holes 161 while blocking the grinding members 140.

Referring to fig. 1 and 3, in some embodiments, in order to enable the ground material to smoothly flow to the discharging part 300, a connection portion between the second rotating shaft 120 and the discharging part 300, i.e., a right end of the second rotating shaft 120, is bent toward an outer side of the second rotating shaft 120 in a radial direction (i.e., in an up-down direction). Therefore, the inner wall of the second rotating shaft 120 can be better jointed with the inner wall of the discharging part 300, and the slurry is prevented from being clamped at the joint or leaking at the joint in the conveying process.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art. Furthermore, the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
