Vertical filter press is a kind of highly efficient equipment using for solid-liquid separation. This kind of filters achieve solid-liquid separation through extrusion, gravity and pump pressure. Its extrusion pressure is bigger and its automation level is higher, comparing with the traditional filter press. Powerful production capacity and high efficiency are significant features of the vertical filter press. The vertical filter presses provided from us have been the international advanced level no matter in technology or quality. It has been widely used in metallurgy, mining, chemical engineering, paper making, food, pharmacy and environment protection, etc.
Working Principle
1.Filtrating Phase: After closing the filter board frames, the slurry is pumped into the filter chambers and then passes through the filter cloth. Meanwhile, the filter cakes are gradually formed on the filter cloth.
2.First Extrusion: The high-pressure water is pumped into the upper chamber and extrude the rubber diaphragms. Then the diaphragms extrude the filter cakes to separate the liquid from filter cakes.
3.Washing(optional): The washing liquid is pumped into the filter chambers, and then passes through the filter cakes and filter cloth. Next, it flows out of the machines via pipes.
4.Second Extrusion: Similar to the fist extrusion.
5.Air Drying: Air is pumped into the chambers and can carry water from the filter cakes, so that the moisture content of the filter cakes can be reduced significantly.
6.Filter Cake Discharge: After finishing the air drying, the filter plate assembly opens and the filter cloth starts to move. The filter cakes move along with the filter cloth and drop down from the filter press. Meanwhile, the filter cloth enters into the washing device and become clean again.
