Gauge reference block is the basic part of the belt filter press, with thrust plates and compression heads at both ends, and The girder connects the two, and the girder is used to support the filter plate, filter frame and compression plate. The following is an introduction to the composition of the reference block of the gage.

The reference block of the inspection tool is connected to the support, and one end of the filter press is located on the foundation. There is a feeding hole in the middle of the thrust plate of the box-type filter press, and there are four holes in the four corners. The holes in the upper two corners are the inlets for washing liquid or compressed gas, and the lower two corners are the outlets. It is usually used to press the filter frame of the filter plate, and the rollers on both sides are used to support the pressure plate to roll on the track of the beam, which is also a load-bearing part. According to the anti-corrosion requirements of the use environment, rigid polyvinyl chloride, polypropylene, stainless steel cladding or new anti-corrosion coating can be selected. When the reference block of the inspection tool is used, the motor rotates forward when it is pressed, and drives the reducer and the gear pair to make the lead screw rotate in the fixed nut, and push the pressure plate to compress the filter plate and filter frame. When the reference block of the inspection tool becomes larger and larger, the load current of the motor increases. When the current value set by the protector is reached, a larger pressing force is reached, and the motor cuts off the power supply and stops rotating. Now it's mostly due to screws and fixing wires. The parent body has a reliable self-locking helix angle, which can reliably ensure the compression state during the working process. When retracting, the motor reverses, and when the pressing block touches the travel switch, retracting stops.

The reference block of the inspection tool is now composed of a filter plate, a filter frame, a filter cloth, and a diaphragm. Both sides of the filter plate are covered with filter cloth. When it is necessary to configure the squeeze diaphragm, a set of filter plates is composed of the diaphragm plate and the side plate. Both sides of the bottom plate of the diaphragm plate of the reference block of the gauge are covered with rubber diaphragms, the outside of the diaphragm is covered with filter cloth, and the side plates are ordinary filter plates. The material enters each filter chamber from the discharge hole on the thrust plate, and the solid particles are trapped in the filter chamber because the particle size is larger than the pore size of the filter medium (filter cloth), and the filtrate flows out from the bottom of the filter plate. When the filter cake needs to be squeezed dry, in addition to pressing it with a diaphragm, compressed air or steam can also be used to pass through the flushing port, and the air flow can flush out the moisture in the filter cake and reduce the moisture content of the filter cake. The reference block of the gauge is also a main filter medium. The selection and use of filter cloth has a decisive influence on the filtering effect. When selecting, the appropriate filter cloth material and pore size should be selected according to the PH value of the filter material, the size of solid particles, etc., to ensure low filtration cost and high filtration efficiency.
