When the filter press is used for heterogeneous separation, long-term work will cause long-term touch between the filter cloth and the filtrate, coupled with strong working pressure, the solid particles in the filter liquid will be more and more attached to the filter cloth. Together, the filter cloth is hand-woven through rigorous hole-making, so that the filter cloth is composed of a special structure, so that the solid particles in the filter cloth can not be discharged. Once more of this particulate matter is deposited, the screening hole limit of the filter cloth will be blocked.

Will greatly reduce the natural filter cloth over the rate, resulting in the role of machinery and equipment is not high. Before cleaning, we require the characteristics of the filter cloth filter device to facilitate the selection of the corresponding cleaning method. When the filtrate is in the acid solution, the filter cloth should be soaked with weak alkali water, usually 10 times for 24 hours, then the filter cloth should be gently wiped several times, then washed with water, and dried to 90% dry.

When cleaning the filter press, the manual method can generally be applied. Gently remove the filter device from the structure and soak in water. If soaked in warm water, the actual effect is stronger, after soaking for an hour, you can use your hands to rub repeatedly, plus detergent is also good. You can also use a soft brush, that is, the general family shoe brush can gently remove the residue on the filter cloth. Hydraulic oil, like the blood of the filter press, has a smooth practical effect, so that the filter press produces working pressure.

For a long period of time, the hydraulic oil will produce emulsification. When the hydraulic oil works in a high-pressure and sealed natural environment, it will wash the surface of the filter press, and the residue will penetrate into the hydraulic oil to accelerate the oxidation and deterioration of the hydraulic oil. At this time, the hydraulic oil can not play the role of maintaining the filter press. Cleaning filter press machinery and equipment also need to pay attention to hydraulic oil, moderate replacement, when the size of the sludge filter equipment and sludge treatment to reach a certain actual effect and concentration value.
