With the advantages of simple operation and good effect, plate and frame filter press is widely used in various industries. How to operate correctly Filter press What about it? Let's have a look!

Operation steps of plate filter press

1、 Pre filtration inspection

Before operation, check whether there is leakage or blockage in the inlet and outlet pipeline and connection, whether the pipeline and filter plate frame and filter cloth are clean, and whether the liquid inlet pump and valves are normal.

Check whether the connecting parts, bolts and nuts of the frame are loose, and they should be adjusted and tightened at any time. The relative moving parts must always keep good lubrication. Check whether the oil level of reducer and nut oil cup is in place, and whether the positive and negative rotation of the motor is normal.

2、 Ready to filter

1. Connect the external power supply, press the button of the operation box to reverse the motor, return the middle roof plate to the appropriate position, and then press the stop button.

2. Hang the clean filter cloth on both sides of the filter plate, and align the material holes. The filter cloth must be larger than the sealing surface of the filter plate, and the hole should not be larger than the pipe hole. There should be no folding to avoid night leakage. The plate frame must be aligned and the order of rinsing filter plate should not be wrong.

Press the forward rotation button on the operation box to press the filter plate on the middle top plate. When a certain current is reached, press the stop button.

3、 Filtration

Open the filtrate outlet valve, start the feed pump and gradually open the feed valve to adjust the feed back valve. Depending on the gradual increase of filtration speed and pressure, generally it should not be greater than 0.6MPa. At the beginning, the filtrate is often turbid and then turned to be clear.

If there is a large leakage between the filter plates, the top tightening force of the middle roof can be appropriately increased. However, due to the capillary phenomenon of the filter cloth, a small amount of filtrate still seeps out, which is a normal phenomenon and can be stored by the tray.

Monitor the filtrated liquid. If turbidity is found, the open flow type can close the valve and continue to filter. If there is a dark flow, stop the machine and replace the damaged filter cloth. When the material liquid is filtered out or the filter residue in the frame is full, the filtration can not be continued, which is the end of one-time filtration.

4、 End of filtration

Stop the feeding pump and close the feed valve.

Press the motor reverse button to retract the middle roof during slag discharging.

Remove the filter residue, wash the filter cloth, filter plate and filter frame, and stack them in order to prevent deformation of the plate and frame. They can also be placed in the filter press in order to prevent deformation. Wash the site and scrub the rack, keep the rack and site clean, cut off the external power supply, and the whole filtering work is finished.
