The first step is compression.
Before operating the filter press, the entire machine must be inspected: check whether the filter cloth is folded or overlapped, and whether the power supply is properly connected. After the inspection, the pressing work can be carried out. Press the "Start" button first, and the oil pump starts working. Then press the "Compress" button again. The piston will push the platen to compress. When the pressure reaches the set maximum point pressure, the hydraulic system stops automatically.
The second step is feeding.
Once the filter press is tightened, the filter press can be fed: the feed pump is turned on, and the feed valve is slowly opened, and the feed pressure is gradually increased to normal pressure. At this time, observe the amount of liquid discharged from the filter press and the leakage between the filter plates. After a period of filtration, the amount of liquid coming out of the outlet hole of the filter press gradually decreases. This indicates that the filter residue in the filter chamber is gradually filling. When the drain does not come out, when there is no liquid or only a very small amount of liquid, it proves that the filter residue in the filter chamber has been completely filled, forming a filter cake. If you need to wash or air dry the filter cake, you can do it later. If you don't need to wash or air dry, you can unload the cake.
Step 3: Wash or dry.
Once the filter press cake is full, the feed pump and feed valve are turned off. Start the washing pump or air compressor, slowly open the washing liquid inlet or air inlet valve, and wash or air dry the filter cake. After the operation is complete, turn off the lotion pump or air compressor and its valve to unload the cake. The fourth step is to unload the cake: first close the feed pump and the feed valve, the washing liquid or the air inlet device and valve, then press and hold the "release" button on the operation panel, the piston rod drives the pressing plate back, after retreating to a suitable position, let go of the "release" button that is pressed, manually pull the filter plate one by one to remove the filter cake, and clean up the filter residue stuck to the sealing surface at the same time, prevent the filter residue from being caught on the sealing surface and affect the sealing performance, resulting in leakage, so far an operation cycle is completed.
