When the fixing chuck is removed from the top of the filter cartridge, the clamping plate is pulled outwards, causing a spring to move the slider along the slide groove. Simultaneously, the spring is stretched, stopping the clamping plate from clamping and fixing the arc-shaped filter screen in the damaged area. This allows for the disassembly and replacement of the arc-shaped filter screen in the damaged area. The filter is easy to disassemble for cleaning the interior of the housing and filter cartridge, and also facilitates the installation and replacement of the arc-shaped filter screen. When the arc-shaped filter screen is damaged, only a portion of it needs to be replaced, eliminating the need for complete replacement and saving costs.

[0017] In this invention, through the feeding inlet, positioning cylinder, and filter chamber, electronic slurry is poured into the filter chamber inside the housing via the feeding inlet. The slurry flows onto the side of the arc-shaped filter screen through the through-hole on the outer wall of the positioning cylinder. The slurry is filtered by the filter disc on the inner wall of the filter chamber. Because the side wall of the filter cylinder is evenly provided with filter holes, the slurry on the inner wall of the filter chamber will flow into the interior of the filter cylinder. When it flows into the interior of the filter cylinder, the arc-shaped filter screen on the outer wall of the filter cylinder will perform secondary filtration on the slurry. After filtration, the discharge port at the bottom of the arc-shaped filter screen is opened to discharge the filtered slurry from its bottom. By rotating the threaded rod, the sealing base plate is removed from the bottom of the housing, and the entire filter cylinder is pulled out from the bottom of the filter chamber for cleaning. This structure can perform multiple filtrations to improve purity and facilitates disassembly and cleaning of the housing. Attached Figure Description
