Factors affecting the effect of plate and frame filter

The function of the plate and frame filter is to remove the particles or suspended substances, so that the substances to be filtered can reach the preset cleanliness The principle of plate and frame filter is to use medium of different sizes to remove impurities in the process of liquid or semi-solid passing through the filter cloth After continuous upgrading, the performance of the plate and frame filter has become more and more powerful, and the materials that can be filtered are more and more diverse, and the filtering effect also meets the requirements of modern production Modern plate and frame filter is more convenient to use and maintain The core part of the filter is the filter membrane After use, the residue on the filter membrane accumulates, which needs to be cleaned in time When cleaning, just unscrew the bottom bolt, drain the liquid, take out the filter cartridge, and then install it again Generally, there are several factors that affect the performance of the plate and frame filter The filtering principle of the plate and frame filter is interception and absorption The commonly used plate and frame filter has been mainly intercepted Intercepting is to achieve different filtering effects according to different aperture settings Another way is adsorption Particles adhere to the filter under chemical action, and are mostly used in the field of pharmaceutical manufacturing The factor that affects the filtration effect Zui is obviously the situation of the filter Different viscosity, flow rate of fluid through the filter will get different filtering effect The slower the flow rate and the longer the contact time between the filter membranes, the better the filtration effect The factors that affect the filtration effect are also related to the operation premise In order to achieve good filtration effect, the lower flow rate is generally selected The slower the flow rate, the better the interception effect and the clearer the filtration In addition, do not change the structure of the filter membrane in the process of filtration It has been proved that the movement of the structure of the filter membrane is harmful to the filtration effect Once the structure of the membrane changes, particles and fibers will be separated from the filter The particle type of the filtered material also affects the filtration effect Generally, filter particles are divided into deformable and non deformable In the process of filtration, the deformable particles will block the mesh and affect the filtration effect The selection of filter membrane is also very important For the filter membrane with the same pore size, the filtering effect of products produced by different manufacturers is also different Consumers must pay attention to this problem when purchasing Different manufacturers have different standards, so it is necessary to attach great importance to the selection of filter membranes produced by different manufacturers There are many factors that affect the effect of the plate and frame filter The normal process and standard operation should be installed during the purchase, operation and later maintenance stage to avoid damage to the filter and affect the filtering effect.
