Working process and principle:
We need to ensure the normal operation of the equipment, check whether the installation of the equipment is in place, whether the valve and the first round are tightly closed to maintain the normal operation of the pressure.
1. Open the oil inlet valve and the overflow valve, turn on the oil pump, and fill the tank with oil. When the liquid 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 night is observed through the sight glass of the discharge pipe, it indicates that the filter cake has formed.
3. Close the circulation valve, open the Qingye valve, and start filtering. Generally, the thickness of the filter cake is controlled at 2-3 cm. The pressure change can be observed from the pressure gauge on the upper part of the tank. During the filtering process, the pressure will increase with the thickening of the filter cake. The oil pump needs to be stopped when the pressure rises, generally up to about 0.4pa.
4. During the cake blowing process, stop the oil pump, close the liquid inlet valve, open the intake valve, and start to blow the cake. The pressure is generally maintained at 0.45-0.5pa. The cake blowing effect is very good. The cake blowing time is generally 15-30 minutes, starting from Qingye Observe through the sight glass and stop blowing the cake when there are few half sight glasses in the clear night.
5. In the process of vibrating slagging, open the sewage valve, return the original liquid from the lower part of the vertebral body to the original liquid tank, open the exhaust valve to return the pressure to zero, open the butterfly valve, and vibrate the slag.
