[0028] In this embodiment, a transmission motor 31 is fixedly connected to the top of the connection cover 2, a threaded rod 32 is fixedly connected to the output end of the transmission motor 31, one end of the threaded rod 32 is rotatably connected to the base 33, a lifting block 34 is threadedly connected to the surface of the threaded rod 32, a connection seat 35 is fixedly connected to one side of the lifting block 34, a connecting seat 35 is rotatably connected to the inside of the connection seat 35, a connecting rod 36 is rotatably connected to one end of the connecting rod 36, a rotating rod 37 is rotatably connected to the inside of the rotating rod 37, an abutment block 38 is fixedly connected to the inside of the rotating rod 37, and the disassembly assembly component 3 is provided to ensure that the transmission motor 31 drives the threaded rod 32 to rotate, and the threaded rod 32 rotates to drive the lifting block 34 to lift and lower to adjust the position of the abutment block 38, so that the abutment block 38 is away from or abuts against the inner wall of the filter cartridge 1, thereby achieving a quick disassembly and assembly effect of the connection cover 2.

[0029] A connecting pipe 42 is fixedly connected inside the connecting cover 2, an air valve 41 is fixedly connected to the surface of the connecting pipe 42, one end of the connecting pipe 42 is fixedly connected to an air bag 43, the bottom end of the connecting cover 2 is located at the bottom of the air bag 43 and is fixedly connected to a limiting plate 44, a movable block 45 is movably connected to one side of the air bag 43, the inside of the movable block 45 is slidably connected to a guide rod 46, a return spring 47 is sleeved on the surface of the guide rod 46, and a rubber sealing ring 48 is fixedly connected to the outside of the movable block 45. By setting up the sealing component 4, it is ensured that gas is input into the air bag 43, the expansion of the air bag 43 pushes the movable block 45 to move along the position of the guide rod 46, and the movement of the movable block 45 drives the rubber sealing ring 48 to move, so as to seal the connecting end of the filter cartridge 1 and the connecting cover 2 to achieve a sealing effect.

[0030] The inner wall of the connecting cover 2 is provided with a slide groove matched with the size of the slider 12. The connecting cover 2 is slidingly connected to the surface of the filter cartridge 1 through the slide groove, ensuring that the installation position of the connecting cover 2 is matched with the position of the slider 12, ensuring that the connecting cover 2 is normally fitted with the surface of the filter cartridge 1.

[0031] The inner wall of the filter cartridge 1 is provided with an abutment groove matched with the size of the abutment block 38. The connecting cover 2 is installed and connected to the inside of the filter cartridge 1 through the abutment block 38, ensuring that the transmission motor 31 drives the threaded rod 32 to rotate, and the rotation of the threaded rod 32 drives the lifting block 34 to lift and push the abutment block 38 to contact the inside of the abutment groove, thereby achieving the effect of disassembly and assembly of the filter.

[0032] There are four groups of abutment blocks 38, which are located on the same center of a circle. The abutment blocks 38 are distributed at equal angles on the inner side of the filter cartridge 1. Anti-slip pads are provided on the surfaces of the abutment blocks 38, ensuring that the transmission motor 31 drives the abutment blocks 38 to abut against the inner wall of the filter cartridge 1 in multiple directions, thereby ensuring the stability of the connecting cover 2 after installation.

[0033] There are five groups of movable blocks 45, which are located on the same center of a circle and are distributed at equal angles inside the connecting cover 2, ensuring that the movable blocks 45 are pushed to move synchronously when the airbag 43 absorbs gas to expand. The movable blocks 45 push the rubber sealing ring 48 at multiple angles to seal the connecting end of the connecting cover 2, ensuring the stability of the sealing of the device connecting pipeline 1.

[0034] The rubber sealing ring 48 is made of nitrile rubber, and the edge contact surface of the rubber sealing ring 48 is in an arc shape, which ensures that the rubber sealing ring 48 has excellent oil resistance, wear resistance and chemical corrosion resistance, and ensures the service life of the device sealing ring.

[0035] The working principle and use process of the present invention: The present invention is an industrial filter that is easy to disassemble and assemble. When the filter needs to be inspected and maintained during use, the transmission motor 31 drives the threaded rod 32 to rotate, and the rotation of the threaded rod 32 drives the lifting block 34 to lift along the surface of the threaded rod 32. The lifting of the lifting block 34 drives the connecting rod 36 to rotate along the inside of the connecting seat 35. The rotation of the connecting rod 36 drives the rotating rod 37 to rotate to push the abutment block 38. When the abutment block 38 is separated from the inner wall of the filter cartridge 1, the connecting cover 2 can be pulled at this time to quickly disassemble and assemble the connecting cover 2 from the inner wall of the filter cartridge 1, ensuring that the device can automatically assemble and disassemble the filter. The filter can be disassembled and assembled to ensure the maintenance efficiency of the filter. At the same time, when the inside of the filter needs to be sealed, the gas is transported to the airbag 43 through the connecting pipe 42, and the airbag 43 is expanded along the inside of the limit plate 44. The expansion of the airbag 43 pushes the movable block 45, and the movable block 45 moves along the direction of the guide rod 46 to push the rubber sealing ring 48. When the rubber sealing ring 48 moves to the connecting end of the connecting cover 2, the filter cartridge 1 is sealed, which ensures that the airbag 43 is sealed with the filter cartridge through the rubber sealing ring 48, ensures that the sealing ring is not in direct contact with the connecting cover 2, and ensures the service life of the sealing ring.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
