A fixing ring 3 is fixedly connected to the top of the outer shell 1. The fixing ring 3 ensures the pressure resistance of the outer shell 1 to avoid deformation after long-term use. A first connecting ring 4 is fixedly connected to the inner wall of the fixing ring 3. A first sealing ring 5 is fixedly connected to the top of the first connecting ring 4. The installed inner shell 2 includes a filter element body 6. A second sealing ring 7 is fixedly connected to the top of the filter element body 6. The second sealing ring 7 is located on the inner wall of the first connecting ring 4. The tightness between the installed inner shell 2 and the outer shell 1 is ensured by the second sealing ring 7. Four limiting plates 8 are fixedly installed in an annular array on the top of the installed inner shell 2. A through hole 9 is opened in the middle of the limiting plate 8. The limiting plate 8 is located above the first connecting ring 4. The installation position of the installed inner shell 2 is limited by the limiting plate 8 to ensure the accuracy of the installation position. A fixing pad 10 is fixedly connected to the inner wall of the outer shell 1. Four installation grooves 11 are opened in an annular array on the inner wall of the outer shell 1.

[0021] Further, such as Figure 3 As shown, the inner shell 2 includes a shell 21, which plays a protective role. A second connecting ring 22 is fixedly connected to the top of the shell 21, which facilitates installation and disassembly. Four first mounting blocks 23 are fixedly installed in a circular array at the bottom end of the second connecting ring 22. A bottom cover 24 is fixedly connected to the bottom end of the shell 21, and a second mounting block 25 is fixedly installed in a circular array at the bottom end of the shell 21.

[0022] Further, such as Figure 4 As shown, the diameter of the cross section of the shell 21 is adapted to the diameter of the cross section of the inner cavity of the fixing pad 10. The shell 21 is located on the inner wall of the fixing pad 10. The stability of the shell 21 is ensured by the fixing pad 10 to avoid shaking of the filter element body 6 during operation, resulting in gaps and affecting the normal use of the equipment. The second sealing ring 7 is connected to the top of the second connecting ring 22, and the position of the limit plate 8 corresponds to the position of the first mounting block 23.

[0023] Furthermore, the position and shape of the first mounting block 23 and the second mounting block 25 are adapted to each other, and the position and shape of the first mounting block 23 and the second mounting block 25 are adapted to the position and shape of the inner cavity of the mounting groove 11.
