When it comes to filter presses, many people should be familiar with them. In fact, the filter press uses unique filtering chemicals to raise the pressure on the objects, and liquids and solids are extracted. This is a filter press, so what are the precautions in the case of maintenance? Let me help you analyze and solve the relevant professional skills.
1, adjust the normal filter press can feed work, each shift work before all mechanical equipment for multi-directional inspection. Industrial equipment shall tighten the prefabricated components of the transmission device and the reducer shall be filled with lubricating grease as much as possible. The four-column hydraulic press shall be tightened to review the remaining oil stored in the automobile oil tank and the working pressure of the hydraulic transmission system. The oil shall be replaced once a year. The working pressure of the hydraulic transmission system shall be cleaned in multiple directions during disassembly. The working pressure of the hydraulic transmission system shall be less than the working pressure of the hydraulic cylinder, but not lower than the standard value of the filter pressure. Too heavy pressure, the forum will damage the parts.
2. It is forbidden to operate the factory when the filter plate is less than the specified number to prevent damage to the parts. Check the arrangement of the filter plate before feeding. The filter cloth shall not be telescopic to prevent very large water seepage. After unloading the cake, the filter plate must be tightly tightened and arranged neatly.
3. The filter plate can be tightened for flushing and filtering only after it is normal. The filtering pressure and filtering ambient temperature shall be within the specified range as far as possible. Excessive filtering pressure leads to water seepage. The plastic filter plate is easy to deform if the filtering ambient temperature is too high. The mixed liquid shall have uniform concentration value during feeding. There should be no mixed debris; After unloading the cake, the filter cloth and filter plate should be cleaned and tidy as far as possible. Residue is not allowed to stick on the protruding surface or in the safety outlet of feeding. Otherwise, the smooth feeding and the sealing performance of the filter plate will be damaged, resulting in unbalanced pressure on both sides of the filter plate and deformation and damage of the filter plate.
4. The selection of filter cloth must conform to the filtration standard specification of filter paddle. Before making the new filter cloth, shrinkage shall occur first. The aperture of the opening shall be smaller than that of the filter plate. The aperture of the filter plate in supporting facilities shall be relatively concentric with the welding bolt. The distribution of the feeding hole shall be close to the material layer. Otherwise, it will cause unclear filtration, low filtration rate, cracking of the cloth cylinder, and adverse effects of the expected filtering purpose.
5. In the early stage of the filter press, the filter is turbid. When a layer of anaerobic granular sludge is caused on the filter cloth, the leachate will turn blue. If the leachate is always turbid or mixed, it may be that the filter cloth is damaged or the hole is deviated from the welding bolt. At this time, close the valve or stop feeding the material to remove the filter cloth. A small amount of water seepage caused by the diffusion of filter cloth is allowed between the filter plates.
6, when moving the filter plate, the force should be uniform and appropriate, can't collision, rolling, to prevent damage to the protruding surface and filter wrench. The filter cloth will harden after being used for a period of time, and its characteristics will be reduced. Therefore, maintenance is required. If any change is found to damage the filtration rate, it can be cleaned with acidic partial alkali with relatively low concentration to make the filter cloth repair effective. If it cannot be repaired, it can be disassembled immediately.
7, slurry, lotion or compressed air shut-off valve, try to open according to the operation steps, can not be opened in addition, muscle diaphragm squeeze compressed air pressure can not exceed the filter pressure.
