The box filter press is designed and manufactured by machine, electricity and liquid. It has reasonable structure, simple and reliable operation and convenient maintenance. The chamber filter press is a batch-operated filter device for solid-liquid separation of various suspensions. Because of its good separation effect, it is widely used in petroleum, chemical, dye, metallurgy, pharmaceutical, food and other industries.
The filter plate of the chamber filter press adopts polypropylene material with good acid and alkali resistance, and the whole structure adopts ductile iron castings, which has long service life.
The box filter press is composed of a filter press filter plate, a compression plate, a filter press filter cloth and a press diaphragm. When the filter plate is pressed, the filter enters a filter chamber formed by a filter mechanism, a filter plate and a compression plate. The solid particles are trapped in the filter chamber by the filter cloth, and the liquid passes through the filter cloth and enters the liquid outlet passage along the groove of the filter plate and the press diaphragm to be discharged outside the machine.
The chamber filter press can perform filter cake washing to further recover the water contained in the filter cake. Usually, compressed air can be introduced from the washing port or the feed port, and a part of the water in the filter cake is taken away when the compressed air passes through the filter cake layer. , thereby reducing the moisture content of the filter cake. After the slurry is filtered in the machine, the cake is washed, pressed, and blown, a slurry having a water content of about 45% can be obtained. The active ingredients after filtration, washing and pressing are sent to the brine section for recycling.
