[0002] The plate and frame filter press was the first machine used in chemical dehydration. Although the plate and frame filter press is generally operated intermittently, the investment in infrastructure equipment is large, and the filtration capacity is relatively low, it has the advantages of large filtration driving force, high solid content of filter cake, clear filtrate, high solid recovery rate, and low consumption of conditioning chemicals.

[0003] The existing patent with publication number CN217367296U proposes a filter press that is easy to replace filter plates. The filter press is equipped with a frame, a baffle, a hydraulic cylinder and a pressure plate, and also includes multiple filtering devices arranged between the baffle and the pressure plate. The filtering device includes a sliding rod, a threaded rod, a movable block and a filter plate. The sliding rod is slidably arranged on the upper part of the frame, and the threaded rod is threadedly connected to the sliding rod. The lower end of the threaded rod passes through the sliding rod and is rotatably connected to the movable block. The lower end of the movable block is provided with a first slide groove along the length direction, and the upper end of the filter plate is provided with a second slide groove along the length direction. The movable block and the filter plate are connected by a connecting rod, and the cross-section of the connecting rod is an "I"-shaped structure.

[0004] Although the above-mentioned filter press can disassemble the filter plate, the disassembly and assembly is relatively cumbersome and troublesome to operate, which increases the burden on the staff, reduces the working efficiency of the filter press, and is time-consuming and labor-intensive. In view of the above problems, a filter press that is easy to replace the filter plate is proposed for improvement and upgrading. Utility Model Content

[0025] Preferably, the disassembly assembly 7 includes a limit frame 71, a protrusion 72 and a push rod 73. The outer wall of the filter plate frame 6 is fixedly connected with protrusions 72 on both sides. The limit frame 71 is provided with a plug-in slot 75. One end of the protrusion 72 is arranged inside the plug-in slot 75. The limit frame 71 is provided with a slide slot 77 on one side of the plug-in slot 75. The lower end surface of the push rod 73 is fixedly provided with a limit plate 74. The limit plate 74 is slidably connected to the slide slot 77. The lower end of the limit frame 71 is provided with a pulley 76 and the pulley 76 is slidably connected to the slide rail 8. The limit frame 71 is internally threaded with a threaded rod 79. The two ends of the threaded rod 79 are respectively fixedly connected with an anti-slip knob 78 and an anti-slip plate. The outer wall of the anti-slip plate is fitly connected to the slide rail 8.

[0026] By rotating the anti-slip knob 78 on the outside of the limit frame 71, the anti-slip knob 78 drives the anti-slip plate at one end of the threaded rod 79 to disengage from the outer wall of the slide rail 8, loosening the limit frames 71 on both sides, and then manually pulling the push rod 73 to drive the limit plate 74 to slide inside the slide groove 77. When the limit plate 74 moves away from above the protrusion 72, the protrusion 72 on the filter plate frame 6 is pulled out from the insertion groove 75, and vice versa, it is convenient for installation, and the filter plate can be quickly disassembled and assembled.
