The filter plate of the filter press is cloudy in the early stage of the filter press
First of all, you can debug the general filter press plate for feeding operation, and all machines should be checked before each shift. Sufficient lubricant must be added to the mechanical compression drive and reduction gearbox; hydraulic is used to check the oil tank The oil storage capacity and the working pressure of the hydraulic station. Usually replace the hydraulic oil once a year, the hydraulic system should always be kept clean, and the hydraulic station should be in a running state. The pressure is less than the working pressure of the cylinder, but not less than the filter pressure. If it is too small, Will cause a lot of leaks and damage the machine.
Secondly, when the pressure filter plate is less than the normal number, stop the operation to avoid damage to the machine. Check the state of the filter plate before feeding. Do not fold the filter cloth to avoid water leakage.
3. The slurry, scrubbing fluid or compressed air valve needs to be activated according to the operating procedure and cannot be activated together. The compressed air pressure during the kneading process should not exceed the filter pressure.
Fourth, the selection of filter cloth needs to meet the technical requirements of the filter plate filter element. In this regard, the filter press works well. Before making a new filter cloth, the water should be shortened. The diameter of the opening should be smaller than the diameter of the filter plate. When When installing the filter plate, the holes between the cloth and the holes should be relatively concentric. The fabric of the paper feed hole should be close to the wall of the filter. Otherwise, the selector will be unclear and pick. Low speed, fabric damage, etc., can not meet expectations filter effect.
5. After it is completely normal, you can press the filter plate and filter it. The filter pressure and filter temperature must be within the normal range. If the filter pressure is too high, it will cause leakage. If the filter temperature is too high, the plastic filter plate Simple deformation. Uniform concentration, no impurities.
6. In the early stage of the filter press, the filter plate of the filter press is dirty. When the filter cake forms a filter cake layer, the filtrate will become clear. If the filtrate is cloudy or mixed by washing, it may damage the plate The hole in the plate and the hole in the plate. At this time, the valve should be closed or the filter cloth should be stopped.
