LW type decanter centrifuge is mainly composed of differential, screw, drum, hood, base, lubrication system, main and auxiliary motors. Its working principle is: the suspension enters the drum through the feed pipe and the spiral discharge port. Under the action of the centrifugal force generated by the high-speed rotation, the solid particles with larger specific gravity are deposited on the inner wall of the drum, and the spiral blades that move relative to the drum continuously scrape the solid particles deposited on the inner wall of the drum and push them out. In the slag hole, the separated clear liquid flows out of the drum through the opening of the slab, and the relative movement between the screw and the drum is realized by the differential. The housing of the differential is connected with the drum, and the output shaft is connected with the screw. When the motor drives the drum to rotate, it also drives the rotation of the differential housing. Because the input shaft is controlled, the planetary gear drives the output shaft to rotate, and the torque is transmitted to the screw according to a certain speed ratio. Continuous separation process.
The LW type decanter centrifuge has a wide range of applications: the volume concentration of solid phase and liquid phase is 10-60%, solid particles with an equivalent diameter of solid particles ≥80μm or suspension of fibrous substances can generally be used for solid-liquid separation or centrifugation Dewatering can greatly reduce the cost of thermal drying of materials and even omit the drying process. The decanter centrifuge is continuous feeding and discharging, and is equipped with washing function. Continuous work, large processing capacity, reasonable power allocation and low energy consumption. The decanter centrifuge has a compact structure, a small footprint, easy installation and maintenance, and the whole machine can be operated in a closed environment.
LW type decanter centrifuge generally can treat distiller’s grains, fermentation broth, sewage, etc.
