Structures and properties:

This machine is horizontal spiral discharging settling centrifuge, the main machine has a column-cone bowl, spiral stoker, differential system, bearing seat, base, cover, main motor,vice motor, and electric control chamber. With the high speed rotating of bowl, form strong centrifugal force, making the sludge dehydrate continuously in 24 hours a day.

The main motor through the triangle belt make the bowl rotating, through the planetary gear differential, make the vice motor and spiral differential speed different,  realize sludge dewatering and pushing material function, That means differential rotating speed control and torque control. because containing solid rate of sludge may have wave motion, by differential speed control system is the guarantee for speed stability, achieve solid content in sludge is constant, the constant torque control make decanter load in a stable state, the separation effect and flocculation is the best state, so as to ensure the safe operation of the centrifuge.

This machine has good seal performance (guarantee without material leak in the process of operation), sludge dewatering work in full seal state, makes the environment clean.

This machine adopts the most advanced international special structural design, especially the spiral stoker, make the sludge concentration dehydration integration characteristics. It has better performance than ordinary centrifuge, more high capacity, better separation effect, save energy and manual work.

Working principle:

2 phase centrifuge:The raw material is pumped into the decanter centrifuge bowl through an inlet and then rotate. The bowl consists of a cylindrical portion and a conical portion. The separation takes place in the cylindrical part of the bowl. Fast rotation produces centrifugal forces ,it makes solid particles with a higher density collected and compacted on the wall of the bowl. The scroll rotates inside the bowl at slightly different speeds. This speed difference is called a differential speed. In this way, the scroll conveys the precipitated particles along the cylindrical portion of the bowl to the conical end of the bowl. At the smallest end of the conical portion of the filter bowl, dehydrated solids leave the filter bowl through the discharge port. The clarified liquid exits through the liquid outlet.

3 phase centrifuge:The working principle of the three-phase horizontal screw discharge decanter centrifuge is similar to that of the standard horizontal screw discharge decanter centrifuge. In terms of the solid density is different, the settling stratification is realized by the centrifugal force field. The lighter liquid phase is closer to the axis of rotation, and the heavier liquid phase is closer to the inner wall of the drum, and the heaviest solid phase settles on the inner wall of the drum, the heaviest solid phase settles on the inner wall of the drum. The light and heavy liquid phases are discharged from the respective channels designed, and the solid phase is discharged by the screw conveyor.

The use of three-phase decanter centrifuge can be divided into:

Light liquid/heavy liquid/solid three-phase separation

Light solid/liquid/heavy solid three-phase separation

Light liquid/solid/heavy liquid three-phase separation

Product application: 

2 phase separation centrifuge is widely used in the production of chemical , printing, metallurgical coal mine, oil production, metallurgy ,iron and steel, fabric ,food, drink, pharmacy starch, dyes and so on, and it can also solve industrial and municipal wastewater. By use it, solid can be dehydrated, liquid can be clarified.

3 phase separation centrifuge is widely used in: cellulose, petrochemical sludge, gutter oil, kitchen waste oil, magnet powder, dye classification, protein, starch, fruit juice, alcohol lees, diving treatment, vegetable oil clarification, pulp recovery, calcium carbonate, glutamic acid, kaolin, graphite, chicken manure, pig manure, metal salt, coagulation sludge, biochemical excess sludge, high temperature coating and other materials separation.
