[0002] Disc filters are a type of high-efficiency solid-liquid separation equipment, widely used in experimental research in fields such as chemistry, biology, and environmental protection. Laboratory disc vacuum filters are a common type of filtration equipment that uses filter cloth to filter raw liquids and achieve solid-liquid separation.

[0003] However, in actual use, due to the different particle sizes of the filter materials, it is necessary to replace the filter cloth with different mesh sizes to adapt to different filtration needs. This replacement process is often quite troublesome and inconvenient, becoming an important factor affecting the efficiency of equipment use and the progress of experiments. When replacing the filter cloth in a traditional laboratory disc vacuum filter, it is usually necessary to disassemble related parts of the equipment, such as the filter disc and filter cloth support. This not only increases the difficulty of operation but may also damage the equipment. At the same time, since there are various ways to connect the filter cloth to the equipment, such as bolt fixing and snap-fit ​​connection, problems such as improper installation of the filter cloth and poor sealing are prone to occur during the replacement process, thereby affecting the filtration effect and the service life of the equipment.
