Decanter centrifuge, as the core separation equipment, plays a very important role in the sludge reduction process. Because the oil sludge separation has a very important index for the oil content of the separated solid. The oil content of the solid after most sludge reduction needs to be controlled below 2%. In order to achieve this index, the decanter centrifuge for sludge separation has a faster wear rate on the pusher than the conventional solid controlled centrifuge because the discharge end is relatively dry.
In order to extend the service life of the centrifuge pusher, the modulated sludge must be sifted through multiple stages before entering the centrifuge to reduce the amount of gravel that wears the centrifuge too much. The vibrating screen as the primary screening provides a certain guarantee for the service life of the centrifuge.
Double-layer vibrating screen with the following characteristics:
First, the bottom frame of the screen box is made of stainless steel, which greatly improves the corrosion resistance and life.
Second, the robot welding process is stable, and the manual intervention is small.
Third, plate frame net, with wedge type screen pressing device, easy to quickly replace the screen.
Fourth, the electric screen box Angle adjustment, convenient and reliable, and mechanical Angle adjustment for backup.
5, screen box sealing patent design, good sealing effect, long service life, and easy to replace.
The first layer of screen can remove the coarse particles, and the second layer of screen can further screen the material. Compact structure saves space.
