Filter Press
The filter press makes use of a special filter medium, exerts certain pressure on the object, and makes a kind of mechanical equipment for liquid dialysis. It is a kind of common solid-liquid separation equipment. It was applied to chemical production in the early eighteenth Century, and is still widely used in chemical, pharmaceutical, metallurgical, dyestuff, food, brewing, ceramics and environmental protection industries.
The filter plate has stable performance, convenient operation, safety and labor saving; metal squeezing tube is processed by seamless steel tube and molded by plastic steel filter plate. It is resistant to high temperature and high pressure and is durable.

Component editor
The structure of the filter press consists of three parts:
The frame is the basic component of the filter press. The two ends are the thrust plate and the press head. The beams on both sides are attached to the two. The beam is used to support the filter plate, the filter frame and the press plate.
1, thrust board: it is connected with the support seat on the foundation of the filter press, in the middle of the thrust plate of the filter press is the feed hole, the four corners have four holes, the upper two corners are the inlet of the washing liquid or the squeezed gas, and the lower two corners are exported (the dark current structure or filter outlet).
2, pressing plate: to compress filter plate filter frame, roller on both sides is used to support the pressing plate rolling on the track of the girder.
3, beam: is a load-bearing component, according to the requirements of the use of environmental protection, the choice of hard polyvinyl chloride, polypropylene, stainless steel coating or new anticorrosive paint coating.
Compacting mechanism
Manual compression, mechanical pressure, hydraulic pressure.
1, manual compression: screw the mechanical jack to push the pressure plate to compress the filter plate.
2, mechanical compaction: compression mechanism consists of motor (equipped with advanced overload protector) reducer, gear, screw and fixed nut. When pressed, the motor is rotating, driving the reducer and the gear to make the screw rod rotate in the fixed wire mother, pushing the pressing plate to compress the filter plate and the filter frame. When the pressure is increasing, the load current of the motor increases. When the current value is set to the protector, the maximum pressure is reached. The motor cuts off the power and stops turning. As the wire rod and the fixed wire mother have reliable self locking helix angle, the motor can reliably guarantee the pressing state in the working process, when the motor is back, the motor reverses when the motor is returned. The pressing block on the pressing plate is pressed back to stop when the stroke switch is pressed.
3, hydraulic pressure: the structure of hydraulic pressure station consists of hydraulic station, oil cylinder, piston, piston rod, piston rod and pressure plate. The structure of the hydraulic station is: motor, oil pump, overflow valve (regulating pressure) reversing valve, pressure gauge, oil way, oil tank. When the hydraulic pressure is pressed tight, the hydraulic station is supplied with high pressure oil, the chamber of the oil cylinder and the piston is filled with oil. When the pressure is greater than the friction resistance of the pressed plate, the pressure plate is slowly pressed to tighten the filter plate. When the pressure is reached to the pressure value set by the overflow valve (displayed by the pressure gauge pointer), the filter plate, the filter frame (plate frame type) ) or the filter plate (wing type) is pressed, the overflow valve begins to unload. At this time, the motor power is cut off, the pressing action is completed, the reversing valve is returned, the pressure oil enters the rod cavity of the cylinder, and when the oil pressure can overcome the friction resistance of the pressed plate, the press plate begins to return. When the hydraulic pressure is automatically pressed, the pressure is controlled by the electric contact pressure gauge. The upper limit pointer and the lower limit pointer of the pressure gauge are set in the numerical value of the process requirements. When the pressure reaches the upper limit of the pressure gauge, the power supply is cut off, the oil pump stops power supply, and the pressure is caused by the leakage and leakage caused by the oil system. When falling to the lower limit of the pressure gauge, the power supply is connected and the oil pump begins to supply oil. When the pressure reaches the upper limit, the power supply is cut off and the oil pump stops supplying oil so that the pressure can be guaranteed in the process of filtering material.
