The silicon carbide ceramic inner ring 3 is installed inside the grinding cylinder 1. Engaging steel blocks 13 are equidistantly installed on the outer side of the silicon carbide ceramic inner ring 3. Engaging grooves 14, which cooperate with the engaging steel blocks 13, are equidistantly formed on the inner wall of the grinding cylinder 1. The engaging steel blocks 13 are all slidably connected to the engaging grooves 14. The cooperation between the engaging steel blocks 13 and the engaging grooves 14 allows for better installation of the silicon carbide ceramic inner ring 3 inside the grinding cylinder 1.

[0033] A rubber sealing ring 4 is installed between the grinding cylinder 1 and the sealing steel ring 2. Three connecting components are located on the outer side of the grinding cylinder 1, and three fastening components that cooperate with the connecting components are located on the outer side of the sealing steel ring 2. The fastening components cooperate with the connecting components to connect the grinding cylinder 1 and the sealing steel ring 2, and compress the rubber sealing ring 4. By using the connecting components in conjunction with the fastening components, the grinding cylinder 1 and the silicon carbide ceramic inner ring 3 can be pressed and fixed to one side of the sealing steel ring 2, thereby compressing the rubber sealing ring 4 and further increasing the sealing effect. At the same time, by replacing the traditional bolt connection with fastening components, the loss of bolts during disassembly can be avoided, facilitating subsequent disassembly, replacement, and maintenance of the equipment, which is beneficial for practical applications.

[0034] A separator 10 is installed at the end of the grinding cylinder 1 furthest from the sealing steel ring 2. A pressure gauge 11 and a discharge port 12 are installed on the outside of the separator 10. The pressure gauge 11 displays the pressure, and the ground material is separated from the separator 10 and discharged from the equipment through the discharge port 12. The other end of the separator 10 extends into the interior of the silicon carbide ceramic inner ring 3. A rubber buffer pad 15 is installed between the inner wall of the grinding cylinder 1 and the outer side of the silicon carbide ceramic inner ring 3. The rubber buffer pad 15 is located on the outside of the separator 10. The rubber buffer pad 15 can seal the silicon carbide ceramic inner ring 3 with the grinding cylinder 1 and also buffer the installation of the silicon carbide ceramic inner ring 3. A sealing sleeve 16 is installed between the outer side of the separator 10 and the silicon carbide ceramic inner ring 3. The sealing sleeve 16 can increase the sealing effect between the separator 10 and the silicon carbide ceramic inner ring 3.

[0035] In one aspect of this embodiment, the connecting assembly includes a connecting block 6 and a trapezoidal groove 7. The connecting block 6 is equidistantly installed on the outer side of the grinding cylinder 1 near the sealing steel ring 2. A triangular reinforcing plate 17 is installed between the outer side of the grinding cylinder 1 and the outer side of the connecting block 6, thereby increasing the connection stability between the connecting block 6 and the grinding cylinder 1. The trapezoidal groove 7 is formed on the top of the connecting block 6.

[0036] In one aspect of this embodiment, the fastening assembly includes a connecting groove 5, fastening screws 8, and a fastening plate 9. The connecting groove 5 is equidistantly located on the side of the sealing steel ring 2 near the grinding cylinder 1. The fastening screws 8 are threaded onto the outer side of the sealing steel ring 2. The fastening plate 9 slides inside the connecting groove 5. Limiting grooves are provided on both sides of the inner wall of the connecting groove 5. Limiting blocks that cooperate with the limiting grooves are installed on both sides of the fastening plate 9. The limiting blocks are slidably connected to the limiting grooves. The cooperation between the limiting blocks and the limiting grooves makes the sliding of the fastening plate 9 inside the connecting groove 5 more stable. One end of each fastening screw 8 extends into the interior of the connecting groove 5 and is rotatably connected to the corresponding fastening plate 9. One end of the fastening plate 9 has an inclined structure that cooperates with the inclined surface inside the trapezoidal groove 7. The rotation of the fastening screws 8 drives the fastening plate 9 to move up and down inside the connecting groove 5, thereby using the inclined surface to push and press the connecting block 6, making it stably installed inside the connecting groove 5.

[0037] Working principle:

[0038] When installing the equipment, first align the meshing steel block 13 on the outside of the silicon carbide ceramic inner ring 3 with the meshing groove 14 and insert it, so that the silicon carbide ceramic inner ring 3 is installed inside the grinding cylinder 1. Then, align the connecting block 6 at one end of the grinding cylinder 1 with the connecting groove 5 and insert it (at this time, the fastening plate 9 is raised to the top of the connecting groove 5 under the action of the fastening screw 8, and will not block the insertion action of the connecting block 6), so that the rubber sealing ring 4 is squeezed between the grinding cylinder 1 and the sealing steel ring 2.

[0039] Next, by tightening the fastening screw 8, the fastening plate 9 is moved toward the connecting block 6. When the inclined surface at one end of the fastening plate 9 contacts the inclined surface inside the trapezoidal groove 7, the fastening screw 8 is tightened again, thereby continuing to move the fastening plate 9. Using the action of the inclined surface, the connecting block 6 is pushed to move continuously into the connecting groove 5, thereby making the grinding cylinder 1 and the sealing steel ring 2 continuously press together, further squeezing the rubber sealing ring 4, thereby improving the sealing effect between the grinding cylinder 1 and the sealing steel ring 2.

[0040] Meanwhile, by changing the traditional bolt connection to a fastening component connection method, the fastening screw 8 and the fastening plate 9 are always located on the sealing steel ring 2, which can avoid the loss of bolts during disassembly, making it convenient for subsequent disassembly, replacement and maintenance of the equipment, which is beneficial to practical applications.
