することを目的とする。However, the above-mentioned conventional device has the advantage that the cleaning water does not scatter around the filter press because the cleaning is performed from above the filter plate to below, but the above-mentioned conventional device does not. However, rather than washing the filter plate, the cloth is washed, and a large amount of washing water is necessary to wash the entire filter cloth. Moreover, a large number of cleaning pipes and a rotating device for the cleaning pipes are required, and the device may be complicated and expensive. The present invention provides a cleaning device that does not obstruct the opening and closing of the filter press, cleans the sealing surface of the filter plate to wash away the adhering filter cake, and when the filter plate is closed, the filter surfaces of the front and rear filter plates are filtered. It is an object of the present invention to provide a device capable of increasing the degree of airtightness of a filtration chamber formed between plates and also a device that does not require cleaning of a filter medium.

When the filter plate is opened and the cake is discharged, the cleaning water is supplied from the cleaning water supply pipe to the liquid supply passage provided on the filter plate. The slag adhering to the sealing surface can be washed away by being radially ejected from the opening of the sealing surface provided in the peripheral portion of the filtering plate to the sealing surface of the opposing filtering plate. If the above-mentioned opening of the liquid supply path is provided at both ends of the upper sealing surface of the filter plate and the upper sealing surface of the stock solution supply port provided at the upper part of the filtration bed, the sealing of the both ends of the filter plate is performed. The washing water flows down the surface to wash away the filter residue on both sides of the seal surface, and the deposit on the peripheral seal surface of the stock solution supply port where the filter residue is likely to adhere is washed off and the sealing property of the filtration chamber when the plate is opened. Can be recovered. If a metal filter medium is laid on the filtration bed, the metal filter medium has a good thinness of the cake, so that the cake can be easily taken out from the filtration chamber by opening the filter plate.
