[0002] Filters are widely used in the chemical industry. Their primary function is to filter solid particles from liquid materials, improving the purity of the liquid to meet the purity requirements of subsequent processes and products. The working principle of a pipe filter is that when the liquid material passes through the filter installed at the equipment pipe mouth, large impurities in the liquid are intercepted in the filter cartridge, and the pure liquid passes through the filter cartridge directly into the equipment. The pipe filter has a simple structure, does not take up space in the equipment and piping layout, and can be quickly installed, removed, and cleaned.

[0003] Existing pipe mouth filters are usually of fixed size. When used in different equipment, they need to be fixed with filters of corresponding models, resulting in poor adaptability. At the same time, flanges and other connectors are used for connection, which makes disassembly inconvenient.

[0028] Among them, there are multiple second threaded rods 12, and the multiple second threaded rods 12 are arranged in a circular equidistant shape. The second threaded rods 12 are connected to the extrusion block 14 through bearings. By turning the knob 13, the second threaded rods 12 are driven to rotate, and then the extrusion block 14 is driven to move horizontally.

[0029] Among them, the extrusion block 14 is arranged in an arc shape, and there are multiple extrusion blocks 14. The bottom of the extrusion block 14 and the top of the sealing ring 10 are located in the same horizontal plane. The arc-shaped extrusion block 14 can better fit with the outer wall of the equipment pipe mouth. The sealing ring 10 limits the extrusion block 14 to prevent the extrusion block 14 from rotating together when the second threaded rod 12 is rotated.

[0030] Among them, a rubber pad is provided on the top of the sealing ring 10, and the gap between the sealing ring 10 and the equipment pipe mouth is filled by the provided rubber pad.

When the top plate 8 moves upward, the angle between the first connecting rod 3 and the second connecting rod 4 increases, and the spacing between the two adjacent second filter wires 2 increases. When the top plate 8 moves downward, the angle between the first connecting rod 3 and the second connecting rod 4 becomes smaller, and the spacing between the two adjacent second filter wires 2 becomes larger. It can be adjusted according to actual usage.

[0035] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
