Horizontal spiral discharge settling centrifuge
Principle of horizontal spiral sedimentation centrifuge:
The horizontal spiral sedimentation centrifuge is mainly composed of high speed, the same speed direction and slightly higher or lower speed than the drum, differential and other components. When the suspension is to be separated into the centrifuge drum, the high-speed rotating drum generates strong centrifugal force to settle the solid particles with higher density than the liquid phase to the inner wall of the drum. Due to the different speeds of the spiral and the drum, the two exist When there is relative motion (i.e. speed difference), the solid phase deposited on the inner wall of the drum is pushed to the outlet of the small end of the drum by the relative motion of the screw and the drum, and the separated liquid is discharged from the other end of the centrifuge. The function of differential (i.e. gearbox) is to form a certain speed difference between drum and screw.
According to the direction of separation of clarified liquid and sediment after the mixed liquid enters the drum, it can be divided into countercurrent structure and downstream structure. In the downstream structure, it can be divided into common downstream structure and full downstream structure.
Main features of horizontal spiral discharge sedimentation centrifuge:
1、 Horizontal spiral discharge sedimentation centrifuge has a wide range of applications, which can be widely used in chemical industry, petroleum, food, pharmaceutical, environmental protection and other solid-liquid separation fields. It can complete solid phase dehydration, liquid phase clarification, liquid-liquid-solid three-phase separation, particle size classification and other separation processes.
2、 The range of solid particle size is 0.005-2 mm, and it can be separated as usual when the size of solid particle is uneven.
3、 Automatic, continuous, long-term operation, convenient maintenance, can be closed operation.
4、 Single machine production capacity, compact structure, small footprint. The operation cost is low.
5、 The moisture content of solid sediment is generally slightly higher than that of filter centrifuge, which is approximately close to that of vacuum filter.
Main application of horizontal spiral discharge settling centrifuge
1、 Separation and dehydration of industrial and domestic sewage
2、 Precipitation washing, classification and dehydration
3、 Dehydration of soybean and wheat protein
4、 Dehydration of fish meal and meat
5、 Distiller's grains dehydration
6、 Purification of fruit juice and dehydration of pulp fiber
7、 Separation and purification of animal and vegetable oils
8、 Separation and purification of coal tar
9、 Classification and dehydration of kaolin and graphite
10、 Classification and dehydration of dyes and pigments
Main dewatering process of horizontal spiral discharge sedimentation centrifuge
The suspension enters the drum from the feed pipe, the solid particles are accelerated to settle to the inner wall of the drum by centrifugal force under the action of centrifugal field, the settled particles are pushed by the blades of the screw conveyor, and discharged from the settling area (straight cylinder section) through the drying area (cone section) to the solid outlet; the clarified liquid phase overflows from the overflow hole. Thus, the solid and liquid phases can be separated automatically and continuously. It can be used in dehydration, concentration, classification and clarification.
