Filter Plate Knowledge

Since the filter press filter plate so important, we have to analyze the filter press filter knowledge it

Filter plate is actually in the filter press beam we can see, the role of the filter plate is used to attach the filter cloth, so that the filter press filter area increases, storage filter, produce solid, thus forming filter cake.

1, the outer shape of the filter plate. The shape of the filter plate is two-sided to the middle of the depression, the bottom there will be numerous blind spots. So why is it designed as a recessed shape? The purpose is to filter the filter in the filter process, the filter cloth to intercept the solid can have a storage space. Then the design of the blind spot also has its own secret, it is to store the solid, the filter plate and filter cake to increase the friction between the effective support from the cake, there is a purpose is to let the condensed out of water can have a normal Of the circulation line, which will help the water out of the equipment quickly, increase the efficiency of the equipment. Which is also a large number of filter plate with the same thickness of the plate with the plate, the purpose of doing so is to make a good pressure to pass one by one to each other, but also to prevent the filter plate space gap, can not withstand strong pressure And rupture damage.

2, the filter plate material. Filter plate is divided into cast iron and polypropylene material, we are mainly used are polypropylene material filter plate, good polypropylene is able to resist oxidation and high temperature. We want to pay attention to the purchase of polypropylene material, shape the same, but some of the polypropylene material is the use of recycled materials, this will affect the quality of the filter plate.

3, the filter plate is how to help the filter to achieve solid-liquid separation. Water in the filter plate through the way. When the filtrate is pumped into the filter chamber by the feed, the filtrate is fed into each filter chamber formed by pressing the two filter plates through the upper or middle diversion piping, respectively. Of course, there is a filter between the filter chambers And the moisture in the filtrate penetrates the filter cloth and is collected at the lower edge of the filter plate, and several holes are designed at the lower edge of the filter plate. These holes are connected in the secondary design, The water discharged from the equipment, so as to achieve a solid-liquid separation.

From these points of view, we should know that both the plate and frame filter press, van filter press, the role of the filter plate are irreplaceable. The role of the filter plate is so important that we should maximize its normal operation. For its maintenance, indispensable.
