装置。[Scope of Claims] 1. After filling and sealing the diaphragm with water while keeping the plate in a closed frame state, the water in the diaphragm is drained while injecting cloth cleaning liquid into the room from the stock solution supply port or the liquid discharge port. After the chamber is almost filled with cleaning liquid, water is poured into the diaphragm and the cleaning liquid in the chamber is pushed out from the stock solution supply port or liquid discharge port, and the cloth cleaning solution is again injected into the room from the stock solution supply port or liquid discharge port. 1. A method for washing cloth in a filter press, characterized in that the cloth is washed by repeating the operation of draining water from the diaphragm several times. 2. First and second cleaning liquid injection/discharge pipes connected to the raw solution supply port and liquid discharge port of the filter press, and a cleaning liquid supply pump commonly connected to the first and second cleaning liquid injection/discharge pipes. , first and second valves arranged in parallel to communicate and cut off the first and second cleaning liquid injection/discharge pipes and the cleaning liquid supply pump; and the first and second cleaning liquid injection pipes. a cleaning liquid discharge and return device commonly connected to the double discharge pipe; and a second cleaning liquid discharge and return device arranged in parallel so as to communicate and cut off the first and second cleaning liquid injection and discharge pipes and the cleaning liquid discharge and return device. a third and fourth valve, a pressure water injection/discharge pipe communicating with the inside of the diaphragm of the filter press, a water injection pump connected to the pressure water injection/discharge pipe, and a water injection pump connected to the pressure water injection/discharge pipe. a fifth valve that communicates with and shuts off the pressure water injection/discharge pipe and the injection pump; and a fifth valve that communicates and cuts off the pressurized water injection/discharge pipe and the drainage return device. A cloth washing device for a filter press, characterized in that it has six valves.
