Analysis of the causes of damage to the filter plate of the plate and frame filter and its solutions

The filter Zui appeared in the 18th century. The structure of the filter at that time was relatively simple. With the advancement of technology, the current filter is no longer a filter in the traditional sense. The current filter capacity is greatly enhanced, and the scope of treatment is also improved. It has expanded a lot. Among them, the ZHUO used in the frame and frame filter is widely used in the fields of chemical industry, brewing, environmental protection, etc. As the core filter plate of the filter, it is often damaged. So what are the reasons for the damage? How to solve these problems?

Fault Analysis: The causes of damage to the filter plate itself are:

1. When the filter plate is not cleaned, sometimes the medium will leak out. Once leaked, the edge of the plate will be washed out with a small ditch. The pressure of the medium will not increase, the mud cake Can't form.

2. If the outlet is blocked by solids or the supply valve is closed or the valve is closed when starting, the pressure is not leaked, causing damage.

3. If the supply is insufficient or the feed contains inappropriate solid particles, the plate frame itself will be stressed too much to be damaged.

4. When the sludge is too thick or the dry block is left, it will cause blockage of the feed port. At this time, there is no medium between the filter plates of the filter, only the pressure of the hydraulic system itself is left. At this time, the plate itself is pressed for a long time. Extremely easy to cause damage.

Corresponding solution:

1. Use nylon cleaning blade to remove the mud from the feed port 2. Complete this cycle, reduce the filter filter plate volume 3. Check the filter filter cloth, clean the drain port, check the outlet, open the corresponding valve, release the pressure 4, carefully Clean the filter plate and repair the filter plate.
