Background technique

The filter press uses a special filter medium to apply a certain pressure on the object to make the liquid dialysis out. It is a kind of mechanical equipment commonly used for solid-liquid separation. It was used in chemical production in the early 18th century, and it is still widely used in chemical, pharmaceutical, metallurgy, dyestuff, food, brewing, ceramics and environmental protection industries.

During the use of the filter press, it is necessary to move the filter plates to separate the adjacent filter plates from each other, so that the impurities between the filter plates can fall; at present, in a certain process of the filter plate, the filter plate needs to pass through the filter plate Units are pulled apart one by one, and the plate pulling process is less efficient, which in turn reduces the cleaning efficiency of the filter press.

Contents of the invention

The purpose of the present invention is to provide a reciprocating quick-drawing system and its control method, the impurities between multiple filter plates can be dropped at the same time, and the efficiency of the plate-drawing process is increased.

The technical scheme provided by the invention is as follows:
