The box Filter Press is an advanced solid-liquid separation mechanical product with integrated technology of machine, electricity and liquid. It consists of four parts: rack part, filter part (filter plate, filter cloth), hydraulic part and electrical appliance part. According to user requirements, you can add automatic pull plate, liquid connection device and so on. Filter plate is the main component of filter press. Its function is to discharge water and store filter cake during the process of filtration.
The filter plate has a protruding platform on the surface of the oil plate and forms a drain groove. Outside the convex platform is a porous plastic screen board. It is riveted on the filter plate with rivets and the filter cloth is outside the screen plate. The filter plate is generally made of ductile iron or cast iron, and the filter plate, which is proud of RE Mg alloy ductile iron, is also widely used. In recent years, non-metallic materials are widely used in foreign countries as filter plates, such as polypropylene filter plates, which are light in weight and long in life.
The working process of the box filter press includes 4 stages: the top filter plate, the pressure filter, the releasing filter plate and the unloading stage.
1, top tight filter plate process: the hydraulic system makes the pressure oil push the piston and the head plate forward, and press the whole filter plate between the fixed tail plate and the movable head plate, so that many hollow filter chambers of the adjacent filter plates are sealed.
2. Pressure filtration process: feeding the coal paddle from the tailstock feed hole to the filter chamber with the feed pump. When all filter chambers are filled with coal slurry, the filtration process begins. The pressure generated by the feed pump causes the filtrate to pass through the filter cloth, the filter net flows along the drain grooves along the filter plate, and the coal slurry remains in the filter chamber. When the coal slurry is filled into the filter chamber, it stops feeding. After a period of time, the coal slurry forms the coal cake, and the moisture is very low. At this time, the filtration process is over.
3, release the filter plate process. When the feed pump is stopped, the hydraulic system is operated for reversing the oil circuit, and the head plate is returned to its original position.
4. The unloading process. When the filter plate is opened, the hook device of the transmission chain is opened, and the cake is lifted and the weight of the filter cake is removed to the conveyor belt.
