Main classification and mechanical composition of pressing mechanism

      The frame is the basic part of the belt filter press. The two ends are the thrust plate and the compression head. The beams on both sides connect the two together. The beams are used to support the filter plate, the filter frame and the compression plate.

A.、Thrust plate: It is connected with the support to place one end of the filter press on the foundation. The thrust plate of the chamber filter press has a feed hole in the middle, and there are four holes in the four corners, the upper two corners The hole is the inlet for washing liquid or squeezed gas, and the lower two corners are the outlets (underflow structure or filtrate outlet).

B.、Pressure plate: used to compress the filter frame of the filter plate, and the rollers on both sides are used to support the pressure plate to roll on the rail of the beam.

C、beam: It is a load-bearing component. According to the requirements of the use environment, it can be coated with rigid polyvinyl chloride, polypropylene, stainless steel or new anti-corrosion paint.

Pressing mechanism

The compression mechanism includes manual compression, mechanical compression and hydraulic compression. Manual compression is to press the filter plate by pushing the compression plate with the screw-type mechanical jack. The mechanical compaction compaction mechanism consists of a motor (equipped with advanced overload protector) reducer, gear pair, screw rod and fixed. Nut composition. When pressing, the motor rotates forward, driving the reducer and gear pair, so that the screw rod rotates in the fixed nut, and pushing the pressing plate to press the filter plate and the filter frame. When the pressing force becomes larger and larger, the motor load current increases. When it reaches the current value set by the protector, a larger pressing force is reached. The motor cuts off the power supply and stops rotating. The reliable self-locking helix angle can reliably ensure the pressing state during the working process. When retracting, the motor reverses. When the pressing block on the pressing plate touches the stroke switch, the retracting stops.

filter mechanism

The filter mechanism is composed of a filter plate, a filter frame, a filter cloth, and a press diaphragm. Both sides of the filter plate are covered by filter cloth. When a press diaphragm is required, a set of filter plates consists of a diaphragm plate and a side plate. Both sides of the base plate of the diaphragm plate are covered with rubber diaphragms, and the outside of the diaphragm is covered with filter cloth. The side plates are ordinary filter plates. The material enters the filter chambers from the material holes on the thrust plate, the solid particles are trapped in the filter chambers because their particle size is larger than the pore size of the filter medium (filter cloth), and the filtrate flows out from the outlet hole under the filter plate. When the filter cake needs to be squeezed dry, in addition to pressing with a diaphragm, compressed air or steam can also be used to pass in from the washing port, and the airflow can flush the water in the filter cake to reduce the moisture content of the filter cake.

filter cloth

Filter cloth is a kind of main filter medium. The selection and use of filter cloth have a decisive effect on the filtering effect. When selecting, choose suitable filter cloth material and pore size according to the pH value of the filter material, solid particle size and other factors to ensure low High filtration cost and high filtration efficiency. When using, ensure that the filter cloth is flat and not discounted, and the pore size is unobstructed.
