When the filter press works for a long time, the solid particles on the filter cloth will be more and more under the action of pressure.
When the filter press is used for solid-liquid separation, long-term work will result in long-term contact between the filter cloth and the filtrate. Coupled with strong pressure, the solid particles in the filtrate will increasingly adhere to the filter. Cloth.
The filter cloth is woven through rigorous perforation, so that the filter cloth has a special structure, and the solid particles in the filter cloth are difficult to discharge. Once these particles accumulate more, the filter pore size of the filter cloth will be blocked. Will greatly reduce the filtering speed of natural filter cloth, resulting in poor equipment function.
Before cleaning, we need to understand the nature of the filter cloth filter in order to choose the corresponding cleaning method. When the filtrate is in the acid solution, the filter cloth should be soaked in weak alkaline water, usually soak 10 times for 24 hours, then gently wipe the filter cloth several times, then wash with water, and dry to 90% dry.
When cleaning the filter press, manual methods can generally be used. Gently remove the filter from the frame and soak it in water. If it is soaked in warm water, the effect is better. After soaking for an hour, you can repeat the rubbing with your hands. It is also good to add detergent. A brush can also be used, that is, a general household shoe brush can gently brush off the impurities on the filter cloth.
The hydraulic oil, like the blood of the filter press, has a smooth effect and pressures the filter press. For a long period of time, the hydraulic oil will emulsify. When the hydraulic oil works in a high-pressure sealed environment, it will wash the surface of the filter press. Impurities will be mixed into the hydraulic oil, which will accelerate the oxidation and deterioration of the hydraulic oil. At this time, the hydraulic oil can no longer protect the filter press. Therefore, when cleaning the filter press equipment, pay attention to the hydraulic oil and replace it in time.
