Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides Figure 1-Figure 4A mechanical seal dynamic and static ring grinding machine shown in the figure comprises: a mounting bracket 1, a grinding cylinder 4 is mounted on one side of the mounting bracket 1, a hopper is mounted on the top of the grinding cylinder 4, a grinding assembly 3 is arranged inside the grinding cylinder 4, and a discharge pipe 6 is installed at the bottom of the grinding cylinder 4; the grinding assembly 3 comprises a grinding frame 31 rotatably mounted inside the grinding cylinder 4 and a grinding hub 32 rotatably mounted on the grinding frame 31, the grinding hub 32 contacts the inner wall of the grinding cylinder 4, a motor 33 is mounted on one end of the mounting bracket 1 relative to the grinding cylinder 4, and the motor 33 is used to drive the grinding frame 31 to rotate; an auxiliary mounting assembly 2 is arranged at the bottom of the mounting bracket 1, and the auxiliary mounting assembly 2 comprises a mounting ear 21 mounted on the bottom of the mounting bracket 1 and a fastening screw 22 screwed on the mounting ear 21.

[0027] As can be seen from the above, when in use, first connect the mounting bracket 1 to the mounting ear 21, then fit the mounting ear 21 to the ground, and at the same time rotate the fastening screw 22 to fix the mounting ear 21 to the ground, and then place the material to be ground into the hopper, and then the material enters the grinding cylinder 4 along the hopper, and then the motor 33 drives the grinding frame 31 to rotate inside the grinding cylinder 4, and then the grinding hub 32 rotates with the rotation of the grinding frame 31, so that the grinding hub 32 rotates along the inner wall of the grinding cylinder 4. Since the grinding hub 32 is rotatably installed on the grinding frame 31, the grinding hub 32 can rotate during the rotation of the grinding frame 31, so that the material is ground more thoroughly, thereby achieving the grinding and crushing of the material. At the same time, the material after grinding is discharged along the discharge pipe 6, which is convenient for the staff to collect the material after grinding.

[0028] refer to Figure 1 , Figure 2 and Figure 6 As shown, the auxiliary screening component 7 includes a screening box 71 installed between the grinding cylinder 4 and the discharge pipe 6 and a receiving tank opened inside the screening box 71, and a detachable screening card plate 72 is installed inside the receiving tank; an auxiliary circulation component is arranged between the grinding cylinder 4 and the screening box 71, and the auxiliary circulation component includes a circulation connecting pipe 73 installed between the grinding cylinder 4 and the screening box 71, one end of the circulation connecting pipe 73 passes through the screening box 71 and extends to the inside of the receiving tank, and the end of the circulation connecting pipe 73 away from the screening box 71 passes through the grinding cylinder 4 and extends to the inside of the grinding cylinder 4; a power component is arranged on the mounting bracket 1, and the power component includes a vacuum pump 74 mounted on the mounting bracket 1.

[0029] Through the above technical solution:

[0030] When the material after grinding inside the grinding cylinder 4 flows to the screening box 71, the material first falls on the screening card plate 72, and then the material slides on the screening card plate 72 by gravity, so that the material after grinding is screened to a certain extent, and then the ground material falls along the bottom of the screening box 71 into the discharge pipe 6 to complete the screening of the material, and then the incompletely ground material flows along the screening card plate 72 to the side of the screening box 71 close to the circulation connecting pipe 73, and then the vacuum pump 74 and the air outlet pipe can effectively blow air into the circulation connecting pipe 73 to form a negative pressure inside the circulation connecting pipe 73, so that the material on one side of the circulation connecting pipe 73 is sucked into the circulation connecting pipe 73, and at the same time, the incompletely ground material is re-transported to the inside of the grinding cylinder 4 through the circulation connecting pipe 73 to realize the secondary processing of the material, effectively prevent the incompletely ground material from being mixed in and affecting the quality of the material, and facilitate the subsequent processing and use of the material.

[0031] In addition, refer to Figure 1 , Figure 2 and Figure 5 As shown, a filter assembly 5 is provided inside the hopper, and the filter assembly 5 includes a filter plate 51 installed inside the hopper, and a disassembly assembly is provided between the filter plate 51 and the hopper; the disassembly assembly includes a guide groove and a guide groove opened on the hopper and a clamping block 52 installed on both sides of the filter plate 51, and guide clamping blocks 53 are fixed on both sides of the clamping block 52, the clamping block 52 is inside the open groove, the guide clamping block 53 is inside the guide groove, and the guide groove is connected to the open groove.

[0032] Through the above technical solution:

Therefore, when the material enters the grinding cylinder 4 through the hopper, it can be filtered to a certain extent through the filter plate 51 to reduce the entry of impurities into the grinding cylinder 4. When the filter plate 51 needs to be disassembled for maintenance and replacement, the above operation is reversed and will not be repeated here, so as to realize the disassembly of the filter plate 51 and facilitate the maintenance or replacement of the filter plate 51.
