Description

Technical Field

[0001] The utility model relates to the technical field of plate-pressed filter presses, and more specifically to a filter assembly of a plate-pressed filter press. Background Art

[0002] Plate filter press is also known as plate and frame filter press. Plate filter press has large filtration area, large flow rate and wide application range. It is widely used in pharmaceutical, chemical, food and other industries, and is also commonly used in feed additive production industry.

[0003] After searching, the utility model patent with announcement number CN212067857U discloses a filter assembly for a filter press, the inner diameter of the rectangular frame matches the filter plate, and the filter plate is located in the rectangular frame, two snap devices are symmetrically arranged diagonally on both sides of the rectangular frame, and two snap grooves corresponding to the two snap devices are symmetrically arranged diagonally on both sides of the filter plate, one end of the snap device is inserted in the snap groove, and the snap device includes a mounting groove opened on the side wall of the vertical end of the rectangular frame, a sliding hole is opened on the inner bottom wall of the mounting groove, and a horizontally arranged snap rod is inserted and slidably connected in the sliding hole; this patent sets the snap device and the elastic mechanism, and the filter plate can be installed and disassembled by pulling the pull rod. The device has a simple structure, fewer parts, and is firmly fixed, which is convenient for the installation and disassembly of the filter plate, and thus convenient for cleaning and maintenance of the filter plate, thereby ensuring the working quality of the filter press. However, the above patent has the following shortcomings: the filter assembly of the plate filter press is composed of a filter frame and a filter plate. After the medium is filtered through the filter holes on the filter plate, the filtered medium is not easy to fall off, and when the filter plate is installed, the card slot on the filter plate needs to be aligned with the card column on the rectangular frame, which is not convenient to operate. For this reason, we propose a filter assembly for a plate filter press. Utility Model Content
