An annular oil groove is provided at the joint between the sealing ring and the sealing ring, and an oil inlet hole connected to the annular oil groove is provided on the sealing ring. In order to facilitate the installation and removal of the sealing ring on the internal mixer, the sealing ring is set as two semicircular sealing tiles. The two sealing tiles are detachably connected by screws. In the prior art, the screws are set on both sides of one end of the two sealing tiles, which is not only inconvenient for installation and removal, but also because the sealing ring is composed of two detachable parts, the annular oil groove is also divided into two parts accordingly. One end of the sealing ring provided with the annular oil groove extends into the internal mixer. If there is an error when installing the sealing ring, it is impossible to see whether the outer end face of the annular oil groove is aligned.

The screws 3 are arranged on both sides of the retaining ring 1 of the sealing ring, which is not convenient for installation and disassembly. In addition, during the installation process, it is not possible to visually see whether the outer end surface of the sealing ring in the internal mixer is aligned and whether the annular oil groove 5 is connected normally. The utility model provides a sealing ring, such as Figure 4-9As shown, it includes symmetrical sealing pad 14 and sealing pad 2, the cross-sections of the sealing pad 14 and the sealing pad 2 are both semicircular, one end of the sealing pad 14 is fixed with a semicircular outer edge 1, one end of the sealing pad 2 is fixed with a semicircular outer edge 2, the outer edge 1 and the outer edge 2 form a circular retaining ring 1, the outer end surfaces of the other ends of the sealing pad 14 and the sealing pad 2 are both provided with semicircular grooves, the two grooves are connected to form an annular oil groove 5, the retaining ring 1 is provided with an oil inlet hole 4, the oil inlet hole 4 is connected with the annular oil groove 5 through an oil guide channel 15; both ends of the outer edge 1 and the outer edge 2 are fixed by The fixing piece 8 is detachably connected together, and a positioning hole 13 and a positioning hole 2 12 are respectively provided at both ends of the fixing piece 8. A matching positioning screw hole 17 is provided on the outer end face of the outer edge 1 corresponding to the positioning hole 13, and the positioning screw hole 17 is matched with a positioning bolt 19. A matching positioning screw hole 2 11 is provided on the outer end face of the outer edge 2 corresponding to the positioning hole 2 12, and the positioning screw hole 2 11 is matched with a positioning bolt 2 10. A matching positioning groove 6 is provided on the outer end face of the retaining ring 1 corresponding to the fixing piece 8, and the fixing piece 8 is detachably fixed in the positioning groove 6 by the positioning bolt 1 9 and the positioning bolt 2 10. The fixing piece and the positioning groove are arranged on the outer end face of the retaining ring, which is convenient for workers to install and disassemble, reduces the difficulty of loading and unloading the sealing ring on the internal mixer, and can also intuitively judge whether the outer end face of the annular oil groove is aligned and whether the annular oil groove is connected normally by observing whether the fixing piece is installed in place.

[0027] The thickness of the fixing member 8 is the same as the depth of the positioning groove 6. This arrangement allows intuitive judgment of whether the outer end faces of the annular oil groove are aligned by observing whether the surfaces of the fixing member and the retaining ring are aligned. This is simple, fast and effective, and improves the accuracy of judgment.

[0028] The fixing member 8 comprises a rectangular block, and both ends of the rectangular block are fixedly connected with semicircular connecting blocks, and the centers of the positioning hole 13 and the positioning hole 2 12 coincide with the centers of the corresponding connecting blocks.

This arrangement improves the accuracy and sealing effect of the connection between the sealing shoe 1 and the sealing shoe 2, cooperates with the fixing part and the positioning groove, and further improves the accuracy of the connection of the annular oil groove.

[0033] By providing the matching positioning groove 6 and fixing member 8 on the outer end surface of the retaining ring 1, it is not only convenient to disassemble and install, but also can intuitively judge whether the outer end surface of the sealing shoe 14 and the sealing shoe 2 2 extending into the internal mixer is aligned, whether the two grooves on the outer end surface are aligned, and whether the formed annular oil groove 5 is connected normally. When the countersunk bolt fixes the fixing member 8 in the positioning groove 6, the surface of the fixing member 8 is flush with the surface of the retaining ring 1, which means that the outer end surface of the sealing shoe 14 and the sealing shoe 2 2 extending into the internal mixer is also flush, and the annular oil groove 5 is connected normally, and there will be no oil leakage. The above has described the embodiments of the utility model, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments.
