The second step material: when the filter press is pressed, the feeding operation can be performed: the feed pump is turned on, and the feed valve is slowly opened, and the feed pressure is gradually increased to the normal pressure. At this time, observe the liquid output of the filter press and the leakage between the filter plates. After filtering for a period of time, the liquid output from the filter press is gradually reduced. At this time, the filter residue in the filter chamber is gradually filling, when the liquid outlet is not out. When the liquid or only a small amount of liquid, it is proved that the filter residue in the filter chamber is completely filled to form a filter cake. If the filter cake needs to be washed or air-dried, it can be carried out subsequently, and the unloading operation can be carried out without washing or air drying.
The third step of washing or air drying: after the filter cake is filled, the feed pump and the feed valve are closed. Open the washing pump or air compressor, slowly open the washing liquid or air inlet valve, and wash or air dry the filter cake. After the operation is completed, the washing machine or the air compressor and its valves are closed, and the unloading operation can be performed.
The fourth step of unloading the cake: first close the feed pump and feed valve, into the washing liquid or air inlet device and valve, and then press the "release" button on the operation panel, the piston rod drives the pressure plate to retreat, retreat to the appropriate After the position, release the “release†button, and manually pull the filter plate to remove the filter cake, and at the same time clean the filter residue stuck on the sealing surface to prevent the filter residue from being caught on the sealing surface to affect the sealing performance and cause leakage. At this point, an operation cycle is completed.
