Description

Technical Field

[0001] The utility model relates to the technical field of pipeline filters, and more specifically, to a filter device which is easy to replace. Background Art

[0002] Pipeline filters are filtering devices installed in pipeline systems to remove impurities, particulate matter and pollutants from pipeline fluids to ensure the normal operation of the pipeline system and the cleanliness of the fluid. Pipeline filters usually include filter housings, filter elements (such as filter screens, filter cartridges, etc.) and inlet and outlet pipe connectors. The existing filter screen structure is fixedly installed inside the filter, making it difficult to remove the filter screen for cleaning after long-term use. It is difficult for operators to effectively clean the filter screen structure inside the filter, which affects the service life of the pipeline filter.

[0003] The utility model with announcement number CN218357869U discloses an easily replaceable pipeline filter. External liquid can be filtered through a first filter screen and a second filter screen. The operator rotates the pressure rod so that the pressure block can press and fix the first filter screen, the second filter screen and the partition. At the same time, the operator can also disassemble and clean the first filter screen, the second filter screen and the partition area by loosening the pressure rod, so that the filter can be removed for cleaning after use, which is convenient for effectively cleaning the filter structure, thereby ensuring the service life of the pipeline filter.

[0004] When the above-mentioned pipe filter is in use, the first cover body and the second cover body are provided to facilitate opening and cleaning of the inside of the main shell. However, when filtering, it is necessary to stop filtering the fluid first, and then clean the impurities adhered to the filter screen. It is inconvenient to clean the impurities adhered to the filter screen, and the use effect is poor. Utility Model Content

[0008] Furthermore, a handle is movably provided at the bottom of the sealing cover, and the top of the handle is fixedly connected to the first rotating shaft.

[0009] It can be seen that in the above technical solution, it is convenient to drive the first rotating shaft to rotate.

[0010] Furthermore, the top end of the sealing cover is fixedly connected to an extrusion frame, and the top end of the extrusion frame is in contact with one of the mounting plates.

[0011] Furthermore, a first gasket is movably provided on the top of the shell, and the first gasket is movably sleeved on the feed spiral tube.

[0012] It can be seen that in the above technical solution, by providing the first gasket, the sealing between the feed coil and the external pipeline can be improved.

[0013] Furthermore, the movable sleeve on the sealing cover is provided with a second gasket, and the top end of the second gasket is in contact with the shell.

[0014] It can be seen that in the above technical solution, by providing the second gasket, the sealing performance between the sealing cover and the housing can be improved.

[0019] 2. The utility model releases the fixation between the sealing cover and the housing through the buckle, moves the sealing cover downward and away from the housing, thereby driving the extrusion frame to move downward, and then releases the fixation between the mounting plate and the housing, and cleans and replaces the filter element, and at the same time cleans the impurities inside the housing. Similarly, the two mounting plates are squeezed and fixed, which is simple to operate and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS
