Horizontal spiral discharging decanter centrifuge working principle and application areas

- Nov 11, 2017-

Horizontal spiral discharging decanter centrifuge in the course of their work mainly by the high-speed drum to drum and turn the same speed and slightly higher than the drum or slightly lower spiral and differential components such as components in the operation When the separated suspension enters the centrifuge drum, the high-speed rotating drum produces strong centrifugal force to settle the solid particles with larger density than the liquid to the inner wall of the drum. Due to the different rotating speeds of the spiral and the drum, There are two relative movement (ie speed difference).

Horizontal spiral discharge sedimentation centrifuge using the relative movement of the spiral and drum to the drum deposited on the inner wall of the solid phase push the small end of the drum outlet, the separated supernatant from the other end of the centrifuge discharged. Differential (gear box) is the role of the drum and the spiral between the formation of a certain speed difference.

Centrifugal settlement of a horizontal screw discharge sedimentation centrifuge is mainly a mixture of solid and liquid added to the cylindrical rotor, the use of which due to the centrifugal force, the settlement of the liquid in the liquid, the sediment after the material will be further affected Centrifugal squeezing.

Horizontal spiral discharging decanter centrifuge out of which the water, in order to achieve the purpose of separation of solids and liquids. Centrifugal subsidence and gravity subsidence are different: Gravity subsidence, material acceleration, equal to the acceleration of gravity, is a constant value; Centrifugal settlement, centrifugal force depends on the particle radius of gyration, and therefore, at the same angular velocity at In different radius of gyration on the movement of particles, the centrifugal force suffered is not the same.

Horizontal spiral discharging decanter centrifuge wide range of applications, can be widely used in chemical, petroleum, food, pharmaceutical, environmental protection and other solid needs. The area of liquid separation. To complete the solid phase dehydration, liquid phase clarification, liquid - liquid - solid, liquid - solid - solid three-phase separation, particle size separation process.
