Filter Press Feed Work

1, Filter Press debugging the normal pressure filter can feed the work, each class before the work to make a comprehensive inspection of the machine. Mechanical compression drive parts and reducer must be added to the lubricating oil; hydraulic pressure to review the fuel tank oil storage and hydraulic pressure station work, hydraulic oil is generally replaced once a year, Filter Press the replacement of the hydraulic system should be a comprehensive cleaning, hydraulic station work pressure is less than the maximum operating pressure of the oil cylinder, but the minimum can not be lower than the filter pressure allowable value, too small will cause larger leakage, the assembly damage.


2, prohibit in the filter board less than the specified number of conditions factory start-up work, lest damage to the machine. Before feeding, check the filter plate arrangement, filter cloth can not have folding phenomenon, to prevent large leakage; Filter Press After discharging the cake, the filter plate must be pressed tightly and neatly arranged.


3, to be all normal after the pressure filter plate pressure filtering, filtration and filtration pressures must be within the specified range, too high filtration pressure will cause leakage, high filtration temperature plastic filter plate easily deformed, feeding when the concentration of suspended liquid evenly. There shall be no miscellaneous material, the filter cloth and the filter plate must be flush and clean, the residue should not be pasted in the sealing surface or the feeding channel, Filter Press otherwise it will affect the smoothness of the feed and the sealing of the filter plate, which causes the imbalance of the pressure on both sides of the filter plate.


4, the choice of filter cloth must conform to the filter technology requirements, new filter cloth before the production should shrink, open hole diameter should be smaller than the aperture of the filter plate, supporting the hole and plate hole should be relative concentric, feed hole cloth should be pressed to the wall, otherwise it will be caused, filtration is not clear, the filter rate is low, the cloth cylinder burst, not up to the intended result of filtration.


5, filter in the initial pressure filter, Filter Press filtering more turbid, when the filter cloth to form a layer of cake after the filtrate will be clear. If filtrate has been cloudy or mixed, it may be a filter cloth breakage or hole and plate hole deviation, at this time to close the valve or stop the feed replacement filter cloth. A small amount of leakage caused by a filter cloth is allowed between the capillarity.


6, moving the filter plate, the force should be evenly appropriate, not collision, beat, so as not to damage the sealing surface and filter wrench. Filter cloth used for a period of time will harden, performance degradation, this need to be regular inspection, if found to have changes affecting the rate of filtration phenomenon, can be the corresponding low concentration of weak acid weak base and cleaning, so that the filter cloth recovery function, can not be restored in a timely manner.


7, slurry, washing liquid or compressed air valve, must be activated according to operating procedures, not simultaneous, compressed air pressure can not exceed the filtration pressure when the diaphragm squeezes
