XMYZ automatic hydraulic box pressure filter

Structural principle                                                       

The structure of the press filter is composed of three parts:

1. Frame: refers to the basic parts of the press filter and both ends are the thrust plate and holddown joint which connects with the beams on both sides. The beams are used to support the filter plate, filter frame and holddown plate.

a. Thrust plate: connects with the support and place one end of the press filter on the foundation. Feeding port is reserved in the middle of the thrust plate with four holes on the four angles, among which, the two holes in the upper side are the inlet of the washing liquid or the press gas while the two in the lower side are either the underflow structure or the filtrate outlet.

b. Holddown plate: used to press the filter plate and filter frame while the roller wheels on both sides are used to support the press plate to roll on the track of the beam.

c. Beam: refers to the bearing member. Rigid poly vinyl hydrogen, polypropylene, stainless steel cladding and new type anti-corrosion coating etc. can be selected according to the anti-corrosion environment of the environment used.

2. Press mechanism: manual press, machinery press and hydraulic press.

a. Manual press: means that the spiral machinery jack drives the press plate to press the filter plate.

b. Machinery press: press mechanism is composed of overload protector reducer, counter gear, lead screw and the fixed screw. When pressing tightly, the motor will be rotate on a clockwise basis, driving the reducer and counter gear to make the screw rotate in the fixed screw pair and promoting the press plate to press the filter plate and filter frame. When the pressing force is bigger and bigger, the load current of the motor will increase; when it increases to the current value set by the protector, it will reach the maximum pressing force. The motor will cut off the power and stop rotating. Since the screw and screw pair owns the reliable self-lock spiral angle, it is able to guarantee the pressing status during the working process. When returning, the motor will rotate on a reverse basis and it will return and stop when the lock block in the press plate contacts the stroke switch.

c. Hydraulic press: the composition of the hydraulic press mechanism consists of the hydraulic station, cylinder, piston, piston rod and the Haff flange card connected by the piston rod and the press plate. The structural composition of the hydraulic station is: motor, oil pump, selector valve of the pressure adjusting of the overflow valve, pressure meter, oil circuit and oil tank. When the hydraulic press mechanism presses, the hydraulic station is responsible for supplying high-pressure oil while the piston cavity formed by the cylinder and piston fills with the oil. When the pressure is larger than the friction resistance operated in the press plate, the press plate will slowly press the filter plate; when the pressing force reach the pressure value set by the overflow valve and displayed by the indicator of the pressure meter, filter plate, frame and plate of the filter frame and the filter plate van-type will be pressed tightly and the overflow valve will start unloading. At this time, the motor power will be cut off and the pressing action is finished. When returning, the selector valve will change the direction and the pressure oil comes into the rod end chamber of the cylinder. When the oil pressure is able to overcome the friction resistance of the press plate, the pressure plate will start to return. When the hydraulic press belongs to the automatic pressure protection, the pressing force is controlled by the pressure meter in the electrical contacts. Set the pointer of the upper and lower limit to the value requested by the process. When the pressing force reaches the upper limit of the pressure meter, the power will be cut off and the oil pump will stop supplying oil. Since the oil circuit system probably produces inner and outer leakage, resulting in the decrease of the pressing force, when it reduces to the pointer of the lower limit of the pressure meter, the power will be connected and the oil pump will start supplying oil. When the pressure reaches the upper limit, the power will be cut off and the oil pump will stop supplying oil. The circulation in such type will guarantee the effect of the pressing force during the process of filtering the materials.
