Two phase or three phase decanter for centrifuge continuous separation of suspension containing density difference

In addition to being a new energy alternative to petrochemical energy and promoting the optimization of energy structure, the development of bio-fuel ethanol industry has two important implications for grains: one is to promote the healthy development of agriculture and increase farmers' income; the other is to improve the ecological environment. The decanter centrifuge successfully served the deepening treatment of distiller's grains after bioethanol distillation.
In these years, Juneng Machinery always insists on producing high-technology centrifugal decanter series painstakingly and obtained several patents. The company supplies its products with many series,various forms, multi-function, high separation factor and multi-purpose and becomes the important supplier of centrifugal decanter domestic and overseas at present.

2. Decanter centrifuge

The decanter centrifuge is a kind of equipment for continuous separation of suspension containing density difference by using the principle of centrifugal sedimentation. Juneng decanter centrifuge includes two-phase decanter centrifuge and three-phase decanter centrifuge. Mainly used in distiller's grain dehydration, protein dehydration, corn oil extraction process.

2.1 Two phase decanter centrifuge

Working principle

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 a larger specific gravity are deposited on the inner wall of the drum , and the spiral blades that move relative to the drum continuously move
The solid particles deposited on the inner wall of the drum are scraped and pushed out of the slag discharge port . The separated clear liquid flows out of the drum through the opening of the liquid layer regulating plate . The relative movement between the screw and the drum , that is , the differential speed is realized by the differential , and its size is controlled by the auxiliary motor.

3.Three phase decanter centrifuge

Working principle

The centrifuge consists of two rotors ,one is called " drum " , and the other is " screw unloader " ( referred to as a screw ) . When the drum rotate at high - speed , with the slurry along the drum , by centrifugal force , and this centrifugal force is many times greater than gravity , so that the solid particles will be separated from the liquid in the centrifuge drum axis , sedimentation to the inner wall of the drum . A screw unloader located in the drum rotates below the speed of the drum and pushes the deposited solid particles to the slag outlet . The differential speed between the outer drum and the screw unloader ( affects the slag pushing Speed ) depends on the gear ratio of the differential and its speed . The two - phase liquid is divided into two layers by centrifugal force . The heavy phase layer is drawn out by the centripetal pump against the wall of the drum and discharged from the heavy phase outlet . The light phase layer is close to the screw end , thrown out by centrifugal force from the overflow port , and then discharged from the light phase outlet . The whole work is continuously completed between the closed upper and lower shells .

4.Advantages of Juneng Decanter Centrifuge

1 . All - round anti - wear protection , wear - resistant parts are equipped to the drum inner wall , slag outlet , outer circle of the slag discharge port , the spiral blade , and the spiral distributing port etc . which are easy to replace on site and greatly reduce maintenance costs .
2 . According to the characteristics of the product ( processing material ) working conditions , optimize the drum length to diameter ratio , speed and drum cone structure .
3 . Intelligently adjust the differential speed and torque according to the product concentration and flow changes . When the feed concentration changes during the dewatering process , the centrifuge can intelligently adjust the slip and torque of the drum and screw .
4 . Choose a planetary gear differential with heavy load and large transmission ratio .
5 . The centrifuge , occupying a small space , is simple to install and debug . This machine is fully sealed operated , which create the good production environment .
6 . The double frequency conversion control is adopted by the main motor and the differential device auxiliary motor to realize stepless speed regulation , which is applicable to a wide range of materials .
