Sludge Thickening Machine-Maintenance Method-Manufacturer
The sludge has a high water content and cannot be directly processed and transported effectively. Now the environmental protection industry chooses to use a sludge thickening machine for sludge thickening to facilitate transportation and processing. When using the sludge thickening machine, it is necessary to do the corresponding maintenance work, then how should the maintenance work? Today, the editor will introduce in detail the maintenance methods of the sludge thickening machine.
1. Only the normal filter press can be used for feeding work, and the whole machine must be inspected comprehensively before each shift. The mechanical compression transmission components and the reduction box must be filled with enough lubricating oil; the hydraulic compression rechecks the oil tank storage capacity and the hydraulic station working pressure. The hydraulic oil is generally replaced once a year. The hydraulic system should be thoroughly cleaned when the hydraulic station is replaced. The working pressure of the hydraulic station should be less than The working pressure of the oil cylinder is high, but it should not be lower than the allowable value of the filter pressure.
2. It is forbidden to start working in the factory when the sludge thickening machine filter plate is less than the specified number, so as to avoid damage to the machine parts. Check the arrangement of the filter plates before feeding. The filter cloth should not be folded to prevent large leakage; after unloading the cake, the filter plates must be tightly pressed and arranged neatly.
3. After everything is normal, the filter plate can be compressed and filtered. The filter pressure and filter temperature must be within the specified range. If the filter pressure is too high, it will cause leakage. If the filter temperature is too high, the plastic filter plate is easy to deform. The concentration of the suspension should be uniform. There must be no impurities; the filter cloth and filter plate must be rinsed after unloading the cake. Residues are not allowed to stick to the sealing surface or the feed channel, otherwise it will affect the smooth flow of the feed and the tightness of the filter plate, which will cause the two sides of the filter plate. Unbalanced pressure causes deformation and damage to the filter plate.
4. The choice of sludge thickening machine must meet the technical requirements of the filter paddle. The new filter cloth should be shrunk before production. The opening diameter should be smaller than the filter plate aperture. When the filter plate is matched, the cloth hole and the plate hole should be relatively concentric. The hole cloth should be close to the wall of the cylinder, otherwise it will cause unclear filtration, low filtration rate, rupture of the cloth cylinder, and the effect of failing to achieve the expected filtering purpose.
5. In the initial stage of sludge thickening machine, the filter is turbid. When a layer of filter cake is formed on the filter cloth, the filtrate will become clear. If the filtrate has been turbid or mixed, it may be that the filter cloth is damaged or the cloth holes are different from the plate holes. At this time, close the valve or stop feeding to replace the filter cloth. A small amount of leakage caused by the capillary phenomenon of the filter cloth is allowed between the filter plates.
6. When moving the filter plate of the sludge thickening machine, the force should be even and appropriate, and no collision or beating is allowed to avoid damage to the sealing surface and the filter handle. After a period of time, the filter cloth will become hard and its performance will decrease. For this reason, regular inspections are required. If changes are found to affect the filtration rate, the corresponding low-concentration weak acid and weak alkali can be used to neutralize and clean the filter cloth to restore its function. If it cannot be restored, replace it in time.
