Description

Technical Field

[0001] The utility model relates to the technical field of filter press assembly installation, in particular to a plate-frame hanging plate connecting device for a vertical filter press. Background Art

[0002] A filter press uses a special filter medium to apply pressure, forcing liquids to seep out. It's a commonly used solid-liquid separation device. It was first used in chemical production in the early 18th century and remains widely used in the chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramic, and environmental industries. The filter plates offer stable performance, easy, safe, and labor-saving operation. The metal cylinder is machined from seamless steel pipe and precision-cast plastic-steel filter plates, offering high-temperature and high-pressure resistance and durability.

[0003] The Chinese patent document, with authorization announcement number CN102652887B, relates to the technical field of solid-liquid filtration separation equipment, and more particularly to a filter press plate-and-frame assembly. Compared to the prior art, the present invention incorporates a sealing strip outside the junction between the first and second sub-frames, eliminating the need to completely disassemble the plate-and-frame assembly before replacing the sealing strip. This makes replacing the sealing strip simpler and more convenient, with lower cost and time, and improves filter press operating efficiency. Furthermore, the filter cloth covers both the main and second sub-frames, and the sealing strip is positioned between them, separating the sealing strip from the material mixture and making it less susceptible to corrosion and damage. This extends the service life of the sealing strip, reduces the number of replacements, improves filter press operating efficiency, and reduces the overall filter press processing costs of the factory.

[0004] In the above-mentioned prior art, when the filter plates of the filter press are squeezed, there are problems such as poor safety and stability and inconvenient installation and connection between components. Therefore, it is necessary to develop a plate-frame hanging plate connection device for a vertical filter press. Utility Model Content
