It is necessary to stop the machine, take out the filter plate, clean it and replace it, otherwise it will affect the filtering effect of the plate filter. When replacing the filter plate, it is necessary to manually lift the filter plate with filter residue from the filter tank. Since the filter plate with filter residue is heavy, two operators are required to stand at the edge of the filter tank to complete the replacement of the filter plate together each time. Improper cooperation between the two operators may easily cause damage to the filter plate, and only one filter plate can be replaced each time. When multiple filter plates need to be replaced frequently, multiple operators are required to work for a long time. Therefore, manual replacement of filter plates has the problem of low replacement efficiency. Utility Model Content
