Technical Field

[0001] The utility model relates to the technical field of platinum catalyst filtering, in particular to a platinum catalyst filtering device. Background Art

[0002] A platinum catalyst filtration device is a device specifically used for filtering and recovering platinum catalysts in the chemical industry. It uses a filter screen, centrifugal force, or other filtration techniques to intercept catalyst particles while allowing the filtrate to pass through, thereby improving the catalyst recovery rate and reducing production costs. The device usually includes components such as a filter barrel, a rotating shaft motor, and a filtrate holding device. It is used to recover expensive platinum catalysts when producing materials such as silica gel, thereby achieving both economic and environmental benefits.

[0003] Currently, a filter is required for filtering platinum catalysts. During the filtration process, due to the influence of pore size, part of the platinum catalyst and filtered solid particles will clog the filter pores, resulting in a decrease in the filter flux. The blockage will reduce the filtration speed, and more frequent filter cleaning or replacement is required. However, the filter is installed inside the container and is generally fixed by multiple sets of bolts. Therefore, when the filter is disassembled, cleaned or replaced, multiple sets of bolts need to be removed, which affects the efficiency of the filter disassembly, cleaning or replacement. Therefore, a platinum catalyst filtration device is proposed. Utility Model Content
