　　Ruichen oil sludge degreasing centrifuge centrifugal oil cement three-phase centrifuge

　　The Ruichen oil sludge degreasing centrifuge centrifugal oil cement three-phase centrifuge is mainly used for solid-liquid separation, that is, separating one solid phase (density) and two liquid phases with different densities. The drum and screw rotate at high speed in the same direction with differential speed, and the material enters through the feeding pipe. Under the action of centrifugal force, solid phase materials deposit on the drum wall to form a sediment layer. Two types of liquid phase materials form a light liquid phase ring and a heavy liquid phase ring, respectively. Starting from the drum wall, a solid phase layer, a heavy liquid phase layer, and a light liquid phase layer are formed in sequence inward. The spiral continuously pushes the solid material deposited on the drum wall to the cone end of the drum and discharges it outside the machine through the slag discharge outlet. The light liquid phase continuously overflows from the overflow port at the large end of the drum, while the heavy liquid phase is discharged through the large end of the drum. Thus achieving three-phase separation.

　　The working principle of the Ruichen oil sludge degreasing centrifuge centrifugal oil cement three-phase centrifuge is that two liquid phases and one solid phase enter the centrifuge and are expanded thousands of times by the centrifugal force field. The solid phase is settled under the action of centrifugal force, and the two liquid phases are also layered, thus achieving solid-liquid three-phase separation and being discharged from the machine body under the action of special mechanisms. The entire feeding and separation process is continuous, closed, and automated.

　　It is mainly composed of components such as drum, screw, differential, frame, housing, and motor. The drum adopts a double cone angle design, and the inner wall of the drum is specially designed with longitudinal concave convex grooves to improve the efficiency of spiral conveying of solid phase. The working surface of the spiral blade has a hard alloy protective layer, which effectively improves the wear resistance life of the spiral blade. The main motor is controlled by the main frequency converter, and the auxiliary motor is controlled by the auxiliary frequency converter. The frequency of the motor can be adjusted arbitrarily. The power supply of the auxiliary frequency converter is provided by the main frequency converter, known as DC common bus power supply. DC common bus power supply realizes energy feedback when the auxiliary motor is in the working state of the generator, which can effectively save electricity.

　　When the material to be separated is transported by the feed pump to the centrifuge drum, the high-speed rotating drum generates strong centrifugal force to settle solid particles with higher density than the liquid phase onto the inner wall of the drum. Due to the different rotational speeds of the screw and the drum, there is relative motion between the two (i.e., adjustable speed difference), and the solid (slag) with higher density settles onto the drum wall. Two phases of clear liquid with different densities form concentric cylinders, with the lighter liquid phase in the inner layer and the heavier liquid phase in the outer layer. The thickness of different liquid rings can be adjusted by adjusting the liquid plate (i.e. the water content in the oil or the oil content in the water can be adjusted). The slag deposited on the wall of the rotary drum is transported by the screw conveyor to the cone end of the rotary drum, and discharged into the solid material tank from the discharge port. Water and oil are discharged from their respective outlets, and the entire three-phase separation process of oil, water, and slag is automatically fed and discharged.

　　The centrifugal oil cement three-phase centrifuge can be used for clarifying or removing impurities from aged oil in oil fields, waste engine oil, catering waste oil, etc.
