Although the plate and frame filter press is generally operated intermittently, the infrastructure equipment investment is large, and the filtration capacity is also low, it is still widely used in some small sewage treatment plants because of its advantages such as large filtration driving force, high solid content of filter cake, clear filtrate, high solid recovery rate, and low consumption of conditioning drugs. After the plate and frame filter press is used, its plate and frame need to be cleaned;

[0003] For example, the public document: CN215250633U, named "Anti-blocking plate-frame filter press for waste mineral oil treatment", includes a bottom plate, vertical plates are fixedly connected to the left and right sides of the top of the bottom plate, the tops of the vertical plates are fixedly connected to the lower ends of the cross plates, two guide rails are fixed to the lower ends of the cross plates, the lower ends of the guide rails are slidably connected to slide seats, the lower ends of the slide seats are fixedly connected to fixed plates, the lower ends of the fixed plates are provided with first limit grooves, the interior of the first limit grooves are rotatably connected to pulling blocks through torsion spring shafts, the inner sides of the fixed plates are provided with slide grooves, the lower ends of the inner sides of the slide grooves are fixedly connected to electric telescopic rods, the interiors of the slide grooves are slidably connected to sliders, and liquid storage boxes are fixedly connected between the inner sides of the sliders.
