Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1-4As shown, in this embodiment, a replaceable wear-resistant sealing device includes: a disassembly mechanism 1, which includes a base plate 111. An annular outer wear-resistant ring 11 is provided on the top of the base plate 111. An upper wear-resistant cover 12 is provided on the top of the annular outer wear-resistant ring 11. Multiple threaded grooves in an annular array of the upper wear-resistant cover 12 are provided with mounting bolts 13. A sealing gasket 14 is provided at the bottom of the upper wear-resistant cover 12. The bottom of the annular outer wear-resistant ring 11 is fixedly connected to the top of the base plate 111, and the sealing gasket 14 is fixedly connected to the bottom of the upper wear-resistant cover 12. Multiple mounting holes 15 are annularly arrayed on the top of the annular outer wear-resistant ring 11. A sealing groove 16 is provided on the top of the annular outer wear-resistant ring 11, and the outer surface of the sealing gasket 14 is mated within the sealing groove 16. The mounting bolts 13 pass through the threaded grooves of the upper wear-resistant cover 12. An annular sealing ring 17 is provided on the top of the base plate 111 near the inner ring of the annular outer wear-resistant ring 11, connected to the internal thread of the mounting hole 15. The bottom of the annular sealing ring 17 is fixedly connected to the top of the base plate 111, and the outer ring surface of the annular sealing ring 17 is fixedly connected to the inner ring surface of the annular outer wear-resistant ring 11. A reinforcing rib 18 is provided in the cavity of the annular sealing ring 17. An upper wear-resistant and anti-corrosion washer 19 and a lower wear-resistant and anti-corrosion washer 110 are respectively provided on the top and bottom of the reinforcing rib 18. The lower wear-resistant and anti-corrosion washer 110 is placed in the cavity of the annular sealing ring 17, and the reinforcing rib 18 is placed in the cavity of the annular sealing ring 17 near the top of the lower wear-resistant and anti-corrosion washer 110. The upper wear-resistant and anti-corrosion washer 19 is placed in the cavity of the annular sealing ring 17 near the top of the reinforcing rib 18.

[0022] In this embodiment, during prolonged use, the upper wear-resistant and corrosion-resistant gasket 19 and the lower wear-resistant and corrosion-resistant gasket 110 of the seal will gradually age, eventually reaching their service life limit. Furthermore, the reinforcing rib 18 may gradually wear down due to long-term friction, resulting in a rough surface. Timely replacement of the reinforcing rib 18 is necessary to ensure the overall effectiveness of the seal. Therefore, the operator can remove the mounting bolt 13 from the mounting hole 15, thereby detaching the upper wear-resistant cover 12 and the annular outer wear-resistant ring 11. After removing the upper wear-resistant cover 12, the reinforcing rib 18, upper wear-resistant and anti-corrosion gasket 19, and lower wear-resistant and anti-corrosion gasket 110 inside the cavity of the annular sealing ring 17 can be replaced. After replacement, the upper wear-resistant cover 12 is placed back on top of the annular outer wear-resistant ring 11, and the sealing gasket 14 will be aligned with the sealing groove 16. The sealing groove 16 and the sealing gasket 14 can achieve a sealing effect, preventing dust and impurities from entering the annular sealing ring 17 from the gap between the upper wear-resistant cover 12 and the annular outer wear-resistant ring 11.

[0023] This utility model provides a replaceable wear-resistant sealing device, the specific working principle of which is as follows:

[0024] After prolonged use, the upper wear-resistant and anti-corrosion gasket 19, the lower wear-resistant and anti-corrosion gasket 110, and the reinforcing rib 18 inside the seal will gradually fail due to aging or wear, thus affecting the overall performance of the seal. In order to ensure that the seal can continue to operate efficiently, the mounting bolts 13 are removed one by one from the mounting holes 15. The removal of the mounting bolts 13 will release the fixing limit on the upper wear-resistant cover 12 and the annular outer wear-resistant ring 11. After removing the upper wear-resistant cover 12, the reinforcing rib 18, the upper wear-resistant and anti-corrosion gasket 19, and the lower wear-resistant and anti-corrosion gasket 110 in the cavity of the annular sealing ring 17 can be replaced. After the replacement is completed, the upper wear-resistant cover 12 is put back on the top of the annular outer wear-resistant ring 11, and the sealing gasket 14 will be mated in the sealing groove 16. The sealing groove 16 and the sealing gasket 14 can achieve a sealing effect.
