Principle, faults and solutions of plate and frame filter press
working principle: The plate and frame filter press consists of five major parts: filter plate, hydraulic system, filter press frame, filter plate transmission system and electrical system. First, hydraulic force is applied to compress the plate and frame group, and the precipitated sludge enters from the middle and is distributed between each filter cloth. Due to the tight plate and frame, the sludge cannot overflow. Under the high pressure of the screw pump and diaphragm pump, the moisture in the mud seeps out of the filter cloth and flows into the return pipe, while the mud cake remains in the cavity. Afterwards, the plate and frame are relieved of pressure, the filter plates are pulled apart, and the mud cake falls down by gravity. The plate and frame filter press is suitable for general suspensions. The solid particle concentration of a suitable suspension is generally below 10% (that is, the moisture content is above 90%). The operating pressure is generally 0.3...
