　　General term: Three phase horizontal screw centrifuge

　　working principle

　　The three-phase horizontal screw centrifuge is mainly composed of a driving part, a rotating drum, and a screw conveyor. It has a compact structure and small volume. Its operation is based on the principle of sedimentation, which means that solid particles with a specific liquid weight precipitate out within a predetermined time. This principle can also be applied to two liquids that have a specific gravity difference and are immiscible. When the material enters the high-speed rotating drum, it rotates synchronously with the drum inside. Due to different densities, the centrifugal force it receives is different. Solid particles with high densities receive centrifugal force, followed by heavy phase liquids (such as water), and light phase liquids (such as oil) are smaller. In this way, a concentric solid layer and two liquid layers are formed from the outside to the inside according to the magnitude of the centrifugal force received. The solid is pushed out by the screw conveyor, and the liquid is discharged from its respective liquid inlet. So the application of a three-phase spiral centrifuge can not only separate the solids in the material, but also separate the two-phase liquids with different densities in the material, that is, it can perform solid-liquid separation.

　　The working process of the oil sludge special three-phase horizontal screw centrifuge oil sludge treatment special three-phase centrifugal machine oil water residue separation equipment is as follows:

　　The high dryness three-phase spiral centrifuge optimizes and combines different stages of the separation process in a limited space.

　　1. Mixing and Acceleration Stage: The sludge and flocculant are mixed and accelerated in a specially designed inlet chamber to ensure that the sludge enters the separation zone in its original state.

　　2. Clarification stage: Under the action of centrifugal force, the flocculated particles quickly separate and settle in the straight section of the drum. The separated supernatant is discharged through a weir located at the end of the drum.

　　3. Compression stage: The screw propeller pushes the settled solid to the discharge end, and the sludge is further compressed under the action of centrifugal force, releasing pore water.

　　4. Bi directional squeezing stage: In the conical section of the drum, the sludge is subjected to a specially designed biaxial squeezing effect, and the screw conveyor is appropriately designed to generate squeezing force along the axial direction. Combined with the compression effect of the centrifuge, further squeeze out the capillary water of the sludge.

　　5. Control solid retention time: When the amount and quality of sludge entering the centrifuge change, continuously control the total amount of solids in the high dryness centrifuge drum to maintain the dewatering effect. This control is achieved through the drive system of the propeller. The propeller drive system can detect the total amount of solids in the drum in real time and automatically adjust the differential speed and compensate for the pushing power.

　　6. Drive technology: The reliable and excellent performance of high dryness centrifuges requires a combination of drum drive and propeller drive. Our company has developed comprehensive and complete drive combinations for all types of sludge dewatering, and can recommend suitable drive combination methods based on specific application backgrounds and requirements.

　　7. Drum drive system: optional methods include: AC motor+frequency converter; AC motor+hydraulic coupling; Other specific methods.

　　8. Spiral propeller drive system: optional methods include: AC regeneration rear drive or front wheel drive (variable frequency) DVF multi-stage planetary control; Hydraulic motor with independent hydraulic pump; Other specific methods.
