Filter Plate

The filter plate is an important accessory in the Filter Press. We can directly observe a whole piece of filter plate horizontally placed on the beam of the filter press with our eyes. The function of the filter plate is to attach the filter cloth to make the filter press The filter area increases, and during storage and filtration, solids are produced, thereby forming a filter cake. Let's talk about the relevant knowledge of the filter plate from various aspects, so that we can clearly understand the filter plate.

First, let's introduce the external shape of the filter plate. The shape of the filter plate is that both sides are concave in the middle, and there will be countless blind spots on the bottom surface. So why is it designed in a concave shape? The purpose is that during the filtering process of the filter press, the solids intercepted by the filter cloth can have a storage space. Then the design of the blind spot also has its own secret, which is to increase the friction between the filter plate and the filter cake when storing solids, and effectively support the filter cake. Another purpose is to make the dialysis water have a normal The circulation route is conducive to allowing water to flow out of the equipment quickly and increasing the working efficiency of the equipment. Among them, the large filter plate will also have several bosses with the same thickness as the filter plate. The purpose of this is to allow the pressure to be transmitted to each other well, and also to prevent the space of the filter plate from being able to withstand strong pressure. And broken and damaged.
Again, let's take a look at the material of the filter plate. Filter plates are made of cast iron and polypropylene. We mainly use polypropylene filter plates. Good polypropylene can resist oxidation and high temperature. When we buy again, we should pay attention to the material of polypropylene, which has the same shape, but some polypropylene materials are made of high-grade _ material, which will affect the quality of the filter plate.
