[0022] Support plates 9 are fixedly connected to both the left and right sides of the outer wall of the filter cartridge 1. Rotating columns 10 are rotatably connected to the upper ends of the two support plates 9. Steering plates 11 are fixedly connected to the upper ends of the two rotating columns 10. Screws 13 penetrate and are threadedly connected to the outer walls of the two steering plates 11. Pressure-receiving plates 12 are fixedly connected to both the left and right sides of the cover 8. Circular holes 14 are formed in the upper ends of the two pressure-receiving plates 12. Pressing discs 15 extending into the inside of the two circular holes 14 are fixedly connected to the lower ends of the two screws 13.

[0023] In this embodiment: When in use, the wear-resistant belt 6 is wrapped around the outer wall of the support ring 18, and the elastic sealing ring 7 is located at the lower end of the support ring 18. Since the elastic sealing ring 7 has good telescopic performance, the wear-resistant belt 6 can be tightened. At the same time, the filter bag 5 is located inside the wire basket 4, and then the wire basket 4 is inserted into the inside of the mounting ring 2 until the support ring 18 enters the inside of the annular groove 3, and the elastic sealing ring 7 contacts the bottom side of the inner wall of the annular groove 3. Then, the cover 8 is inserted into the inside of the filter cartridge 1. At this time, the O-ring 16 is squeezed inside the filter cartridge 1, so as to seal between the cover 8 and the filter cartridge 1. Then, the two turning plates 11 rotate respectively along with the two rotating columns 10, and at the same time drive the two screw rods 13 and the two pressing plates 15 to rotate until the two pressing plates 15 correspond to the positions of the two round holes 14. Then, the two screw rods 13 are rotated, so that the two pressing plates 15 move downward and enter the two round holes 14 respectively. Then, the pressure-receiving plate 12 is pressed downward by the two pressing plates 15, and at the same time, the cover 8 and the four pressing rods 17 are pressed downward. When the two pressure-receiving plates 12 move downward to a certain position, the four pressing rods 17 apply pressure to the support ring 18, and at the same time, the elastic sealing ring 7 is tightly squeezed through the support ring 18. Therefore, the elastic sealing ring 7 can prevent liquid from leaking from the gap inside the mounting ring 2, completing the installation of the filter bag 5. When it needs to be removed, only the opposite steps need to be carried out, thus simplifying the installation and disassembly steps, further achieving the purpose of facilitating the disassembly, cleaning or replacement of the filter bag 5 and improving the operation simplicity.

[0029] In this embodiment: By providing the two positioning plates 21, the installation positions of the two pressure-receiving plates 12 can be positioned.

[0030] As a technical optimization solution of the utility model, the lower ends of the two positioning rods 20 are both hemispherical structures.

[0031] In this embodiment: by setting the lower ends of the two positioning rods 20 as hemispherical structures, it is convenient for the two positioning rods 20 to enter the interiors of the two positioning holes 19.

[0032] As a technical optimization solution of the utility model, handles are fixedly connected to the upper ends of the two screws 13.

[0033] In this embodiment: by providing two handles, it is convenient to rotate the two screws 13 respectively.

[0034] Working principle: When in use, first wrap the wear-resistant belt 6 around the outer wall of the support ring 18, and make the elastic sealing ring 7 located at the lower end of the support ring 18. And because the elastic sealing ring 7 has good telescopic performance, the wear-resistant belt 6 can be tightened. At the same time, place the filter bag 5 inside the wire basket 4, then insert the wire basket 4 into the inside of the mounting ring 2 until the support ring 18 enters the inside of the annular groove 3, and the elastic sealing ring 7 contacts the bottom side of the inner wall of the annular groove 3. Then insert the cover 8 into the inside of the filter cartridge 1, and at the same time make the two positioning rods 20 enter the interiors of the two positioning holes 19, so as to limit the installation position of the cover 8. At this time, the O-shaped sealing ring 16 is squeezed inside the filter cartridge 1, so as to seal between the cover 8 and the filter cartridge 1. Then make the two turning plates 11 rotate respectively with the two rotating columns 10, and at the same time drive the two screws 13 and the two pressing plates 15 to rotate until the two pressing plates 15 correspond to the positions of the two round holes 14. Then rotate the two screws 13 through the two handles, so that the two pressing plates 15 move downward and enter the interiors of the two round holes 14 respectively. Then press the pressure receiving plate 12 downward through the two pressing plates 15, and at the same time press the cover 8 and the four pressing rods 17 downward. When the two pressure receiving plates 12 abut against the two positioning plates 21, the four pressing rods 17 apply pressure to the support ring 18, and at the same time tightly squeeze the elastic sealing ring 7 through the support ring 18. Therefore, the elastic sealing ring 7 can prevent liquid from leaking from the gap inside the mounting ring 2, and the installation of the filter bag 5 is completed. When it needs to be disassembled, just perform the steps in the reverse order, thus simplifying the installation and disassembly steps, further achieving the purpose of facilitating the disassembly, cleaning or replacement of the filter bag 5 and improving the operation simplicity.

[0035] The above are only the preferred embodiments of the utility model and are not used to limit the utility model.
