Ceramic filter press maintenance and precautions l, the normal filter press can be commissioned before feeding, the entire machine should be fully inspected before each shift. The mechanical compression transmission parts and the reduction gearbox must be filled with lubricating oil; the hydraulic pressure is used to check the oil storage capacity of the fuel tank and the working pressure. The hydraulic oil is generally replaced once a year. The hydraulic system should be fully cleaned during replacement. The working pressure is less than the maximum working pressure of the cylinder, but the minimum can not be lower than the allowable value of the filtering pressure. If it is too small, it will cause a large leakage, and the assembly will damage the machine. 2. It is forbidden to start the work in the case where the filter plate is less than the specified quantity, so as to avoid damage to the machine. Check the arrangement of the filter plates before feeding. The filter cloth should not be folded to prevent large leakage. After the cake is unloaded, the filter plates must be tightly packed and aligned.
3. After all normal, the filter plate can be pressed and filtered. The filtration pressure and filtration temperature must be within the specified range. If the filtration pressure is too high, it will cause leakage. The filtration temperature is too high. The plastic filter plate is easily deformed. The concentration should be uniform. There must be no mixed materials; after the cake is unloaded, the filter cloth and the filter plate must be rinsed clean, and the residue is not allowed to be stuck in the sealing surface or the feeding channel, otherwise the smoothness of the feed and the sealing property of the filter plate will be affected, so that the two sides of the filter plate Unbalanced pressure causes damage to the filter plate.
4. The selection of the filter cloth must meet the filter technology requirements of the filter pad. The new filter cloth should be shrunk before the production. The diameter of the opening should be smaller than the hole diameter of the filter plate. When the filter plate is matched, the hole and the plate hole should be relatively concentric. The cloth should be close to the wall of the tube, otherwise it will cause, the filtration is unclear, the filtration rate is low, and the cloth barrel is broken, which does not achieve the intended filtering effect.
