Unmatched Filtration Performance Experience Silver Pressure Leaf Filters with 1-80m3/h Capacity

What is the mechanism of filter?
The straining, interception, diffusion, and inertial impaction mechanisms rely upon media filters to accomplish filtration, while electrostatic attraction is typically obtained by charging the particulate as part of the filtration mechanism.

Filter slag discharge process

With the increase of the filtration volume of the bleaching earth, the filter cake layer becomes thicker and the filter resistance increases, and the pressure in the tank rises. When the pressure gauge on the upper part of the filter shows 0.4Mpa, stop sending the bleaching warth to the filter tank. The mixed liquid, turn on the air compressor, and input air into the filter tank through the pipe through the overflow port. Under the action of the air pressure, the oil in the filter cake is gradually pressed out and returns to the decolorizing pot or mixing tank through the pipe. After 30 minutes, the filter cake is pressed dry and the air input into the filter is stopped. When the pressure gauge on the upper part of the filter shows 0, open the butterfly valve, start the vibrator, and start the slag discharge. When the slag is drained, close the butterfly valve And all valves, start the next round of filtration.

Working principle

Vertical pressure leaf filter, the filter pump pumps the filtrate into the tank through the liquid inlet pipe, and fills it up. Under the action of pressure, the solid impurities in the filtrate are intercepted by the filter on the filtrate, and a filter cake is formed on the filter. The filtrate passes through the filter screen, enters the liquid outlet pipe and flows out of the tank through the filter nozzle, so as to obtain a clear filtrate. As the filtering time increases, more and more solid impurities are trapped on the filter screen, which makes the thickness of the filter cake increase continuously, which increases the filtering resistance and the pressure in the tank. When the pressure rises to a certain value, it needs to be discharged. Stop inputting the filtrate into the tank and blow compressed air into the tank through the overflow pipe, put the filtrate in the tank into other containers, and blow dry the filter cake. Turn off the compressed air, open the butterfly valve, start the vibrator to vibrate the filter leaf, shake off the filter cake on the filter screen and discharge it through the slag discharge port under the tank.
