Automatic recessed plate membrane filter press
(Hydraulically controlled\automatically pull plate)
Structure and working principle
The following diagram is the Structure of filter press. In the diagram, 2 represent the fixed head plate which is fixed on thrust plate 1, 6 represent the mobile tail plate which is fixed on the movable compression plate. Between these two end-plate there are diaphragm plate 3 (diaphragm, diaphragm core board, flange) \ filter cloth 4 and filter plate 5 arranged in order. All filter plates are placed on the beams 8 by their two handles which are installed on the both sides respectively. All of the filter plates can be moved horizontally along the beam. The front- end of piston rod is hinged with the movable compression plate 7. In the hydraulic thrust, the piston pushes the movable compression plate. Thus all of the filter plates and filter cloth are pressed in the rack. When the hydraulic pressure reached the pressure that the machine need, you can revolve the switch to automatic packing position "I". Thus you can feed the slurry to filter. Electrical contacts are automatically regulated in the upper and lower limits. After filtration, compressed air is LED in through the diaphragm plate to squeeze the cake, reducing residue moisture content. Note: 1. While compressed air is LED in through the diaphragm plate, it is important to maintain the original pressure. 2. When the compressed air is not drained, you don't remove filter cake.
For the desire of the customer, the filter press can be assembled with the shift device of filter plate and the suspension device of filter cloth. This can automatically pull plates piece by piece, discharging cake and collecting liquid.
