Crude Oil Leaf Filter Press Automatic Slag Discharge Closed Clay

Yuwei Crude Oil Decolorization Clay Activated Carbon Filter Automatic Slag Discharge Closed Leaf Oil Filter​

●Operation process

1. Open the oil inlet valve and overflow valve, turn on the oil pump, and inject oil into the tank. When the liquid outflow is observed from the overflow pipe sight glass, it means that the raw material liquid has filled the tank.

2. Close the overflow valve, open the circulation valve, and start the circulation, about 5-10 minutes, when the clear liquid is observed from the liquid outlet sight glass, it means that the filter cake has been formed.

3. Close the circulation valve, open the clear liquid valve, and start filtering. Generally, the thickness of the filter cake is controlled at 2-3cm, and the pressure change can be observed from the pressure gauge on the upper part of the tank. in the past
During the filtration process, with the thickening of the filter cake, the pressure rises, generally when the pressure reaches about 0.4Mpa, the oil pump needs to be stopped.

4. The process of blowing cake. Stop the oil pump, close the liquid inlet valve, open the inlet valve, and start to blow the cake. The pressure is generally maintained at 0.45-0.5Mpa. At this time, the cake blowing effect is better.
The cake time is generally 15-30 minutes, which can be observed in conjunction with the clear liquid tube sight glass.

5. In the process of vibrating slag discharge, open the blowdown valve, return the raw liquid in the lower part of the cone to the raw liquid tank, open the exhaust valve, make the pressure return to zero, open the butterfly valve, and vibrate to discharge.
Reminder: You can restore all valves] to their original positions (ie close the valves) and wait for the next filtration.
