How to operate the filter press

How to operate the filter press：

Steps:

      First step compaction: Check the whole machine before operation of the filter press: check whether the filter cloth is discounted or overlapped, and whether the power supply is properly connected. After checking, the pressing operation can be carried out. First press the “start” button, the oil pump starts to work, and then press the “press” button, the piston pushes the pressing plate to compress, when the pressing force reaches the adjusted high point pressure , The hydraulic system automatically trips and stops.

The second step feed: when the filter press is compressed, the feed operation can be carried out: turn on the feed pump, and slowly open the feed valve, the feed pressure gradually rises to the normal pressure. At this time, observe the discharge of the filter press and the leakage between the filter plates. After filtering for a period of time, the amount of liquid from the outlet of the filter press gradually decreases. At this time, it indicates that the filter chamber is gradually full of residues. When the outlet does not come out When there is liquid or only a small amount of liquid, it is proved that the filter residue in the filter chamber has been completely filled to form a filter cake. If the filter cake needs to be washed or air-dried, it can be carried out later. If no washing or air-drying operation is required, the cake can be unloaded.

The third step is washing or air-drying: After the filter cake of the filter press is full, shut down the feed pump and the feed valve. Turn on the washing pump or air compressor, slowly open the washing liquid or air inlet valve to wash or air-dry the filter cake. After the operation is completed, close the lotion pump or air compressor and its valve, and then the cake unloading operation can be carried out.

The fourth step is to unload the cake: first close the feeding pump and the feeding valve, the washing liquid or the air inlet device and the valve, and then press and hold the “release” button on the operation panel, the piston rod drives the pressure plate to retreat, and retreat to a suitable level After position, release the pressed “release” button, manually pull the filter plate one by one to remove the filter cake, and at the same time clean up the filter residue sticking to the sealing surface to prevent the filter residue from being trapped on the sealing surface, affecting the sealing performance and causing leakage . At this point, an operation cycle is completed.
