Description

Technical field:

[0001] The utility model relates to the technical field of filter press equipment, in particular to an improved filter plate structure of a filter press. Background technology:

[0002] The filter press is the main filtering equipment in the solid-liquid separation industry. During filtration, the material enters the filter chamber through the central feed hole of the filter plate, and the particles in the material are intercepted by the filter cloth installed in the filter chamber to form a filter cake, and the filtrate is discharged from the four corner outlet holes of the filter plate to achieve the purpose of solid-liquid separation; the filter plate is the most core component of the filter press equipment. Filter cloths are installed on both sides of the filter plate during use. After a long period of use, the filter cloths are inevitably blocked or broken, so the filter cloths need to be replaced regularly. In the prior art, when replacing the filter cloth (the filter cloth is connected by two filter cloth units), it is necessary to roll one of the filter cloth units into a columnar shape, pass the columnar filter cloth unit through the central feed hole of the filter plate, and then unfold the two filter cloth units, hang the hanging holes of the filter cloth one by one on the hanging pins of the filter plate, and then fasten the two sides and bottom of the filter cloth unit to the filter plate with binding ropes one by one, and then complete the installation of a filter plate and filter cloth. A filter press has dozens of filter plates, the workload is huge, the work efficiency is low, and the normal production is affected, which needs to be improved urgently. Utility model content:

[0003] The utility model aims to provide an improved filter plate structure of a filter press to solve the technical problems of complex operation and low working efficiency of filter cloth replacement in the prior art.

[0004] The content of the utility model: an improved filter plate structure of a filter press, which includes a vertically arranged base plate, with pressing frames arranged on both sides of the base plate, the pressing frame being used to press and fix the filter cloth on the base plate, a hanging pin being connected to the top of the pressing frame, and opposing clamping components being arranged on both sides of the pressing frame, the opposing clamping components being slidably connected to the pressing frame, and the opposing clamping components being used to drive the pressing frame to clamp or loosen the filter cloth.

[0005] Furthermore, the opposing clamping assembly includes racks respectively mounted on the two pressing frames, the racks meshing with gears, the gears rotatably mounted on the base plate, and a turning handle is mounted on the gears.

[0006] Furthermore, a limit pin is slidably inserted into the turning handle, and a plurality of limit holes matching the limit pin are opened on the base plate.

[0007] Furthermore, a sliding block is connected to the rack, a sliding groove is provided on the base plate, and the sliding block is slidably connected to the sliding groove.

[0008] Furthermore, a rubber ring gasket is installed on the inner side of the pressing frame.

[0009] Furthermore, frosted surfaces matching the shape of the rubber ring pad are provided on both sides of the substrate.

[0010] The beneficial effects of the utility model are as follows: the utility model has a simple structure, and pressure frames for fastening the filter cloth are designed on both sides of the filter plate, and opposing clamping components are designed to drive the clamping or loosening action of the pressure frames. Compared with the traditional filter cloth replacement method, a large number of strapping operations are eliminated, which saves time and effort, and effectively improves the work efficiency of installing the filter cloth. It is worthy of large-scale promotion and use. Description of the drawings:
