Portable Plate Pressure Filter Press of hydraulic Press

What is the difference between diaphragm filter press and plate and frame filter press?

People often think that the plate and frame filter press and the diaphragm filter press are the same. In fact, the performance of the plate and frame filter press and the diaphragm filter press are different. The filter press and the diaphragm filter press are regarded as the same machine. The following Meibang Machinery will introduce the difference between the plate and frame filter press and the diaphragm filter press in detail. First of all, the basic principle and structure of the plate and frame filter press and the diaphragm filter press are the same, the difference is that the filter plate used by the diaphragm filter press has a diaphragm cavity on both sides. Diaphragm filter plates and filter plates of the same shape are arranged at intervals to form filter chambers with a certain volume. After the material is filtered, a certain pressure of gas (liquid) is injected into the diaphragm cavity to make the diaphragm bulge and reverse the filter cake spinning. In order to achieve the purpose of reducing the moisture content of the filter cake. Secondly, compared with the filter plate of ordinary box or plate and frame filter press, the diaphragm filter plate has two filter surfaces that can move back and forth - the diaphragm. When a pressing medium (such as compressed air) is introduced behind the membranes, these movable membranes bulge in the direction of the filter chamber, which means that after the filtration process, the filter cake is pressed again under high pressure. The benefits brought to you by the membrane filter plate are: the filtration process equipped with the membrane filter plate, the moisture content of the filter cake can be 10-40% lower than that of the ordinary filter plate. Can save you a lot of follow-up costs. Third, at the same time, when washing the filter cake, the pressing of the diaphragm can make the amount of washing water less and the effect is better.
