Selection method of filter media in filter press

the selection method of filter media in filter press is mainly selected according to the characteristics of filter press. Moreover, today's filter press is widely used in chemical industry, pharmacy, metallurgy, and then through a series of optical elements, the gap outline of the tested sample is clearly projected onto the projector, dyes, food, brewing, ceramics, environmental protection and many other industries, and it is classified as van filter press, plate and frame filter press, belt filter press, vertical filter press, diaphragm filter press, etc, Therefore, scientific methods are needed for the selection of filter cloth of filter and filter press

the selection method of filter media in the filter press is mainly based on the characteristics of the filter press. Moreover, today's filter press is widely used in many industries such as chemical industry, pharmacy, metallurgy, dyes, food, brewing, ceramics and environmental protection, and is classified into box filter press, plate and frame filter press, belt filter press, vertical filter press, diaphragm filter press, etc., so the selection of filter press and filter cloth of filter press requires scientific methods

(1) consider the chemical and physical properties of the material and choose the material of the filter cloth. We should carefully understand the specific information provided by fabric merchants

(2) it is necessary to meet the filtration accuracy of the filter press, that is, the permeability of the filter cloth. Although the filter cloth plays a very important role in the initial filtration accuracy of the filter press, the higher the initial filtration accuracy is, the better. It should be considered that the filtration accuracy can meet the minimum requirements. Because after the filter press forms a filter layer for a period of time, the interception effect of the filter cloth is very small. Forming a good filter layer is the key to the use technology of the filter press

(3) the peeling performance of the filter cake also needs special attention when selecting and matching the filter cloth. Generally speaking, the surface of the filter cloth is smooth and flat. The faster and thorough the peeling of the filter cake, what are the common faults and solutions of the ring stiffness tester for filtering pipes? Short operation time leads to high efficiency. The filter cake adheres to the filter cloth and is not easy to peel off, which will prolong the operation time of the filter press and reduce the work efficiency. However, it takes a lot of time and energy to replace the filter cloth

(4) when selecting filter cloth, pay attention to the filter cloth with good regeneration performance. The filter cloth with good regeneration performance can be washed directly on the filter press to reduce the number of cloth changes. After simple treatment (drying, washing, etc.), the filtration efficiency of the replaced filter cloth is restored to more than 80%

(5) finally, it needs to be specially considered to filter the materials with the selected filter cloth, because the use technology of the filter press is an experimental technology. Carry out small sample real aircraft engine turbine disk and pop can inspection for material filtration Inspect the filtration rate, interception effect, moisture content of filter cake, cake unloading performance, regeneration performance, etc. of the filter cloth
