The decanter centrifuge is suitable for solid-phase dewatering, liquid-phase clarification and separation, liquid-liquid-solid three phase separation and size-grading of various suspensions with solid-phase particle sizes of 0.005-15mm, consistency of 1-40% and temperature of ≤ 100°C, esp. for separatong the suspensions whose consistency and particle size vary greatly and for which recovery of filter cloth is difficult, such as treatment of PVC resins, ammonium sulfite, barrium carbonate, strontium sulphate, lithopone,starch, diatomite, plaster, bauxite, soybean protein, peanut protein, fruit juice, drinks, vegetable oil, citric acid, powder of blood, powder of titanium white, kaolin clay and drilling mud, etc., and dewatering of washed coal and fine coal, purification of waste oil, treatment of grain stillage liquid waste and municipal sewage and mineral classification. Besides, it is suitable for waste water treatment of electric power plant sludge, printing and dyeing sludge, paper manufacture sludge.
The solid drum is internally installed with a concentric discharge screw As they rotate in the same dJreotion at a high speed, They have a certain rotational speed difference, which is caused by the driving system and the differential case Suspension enters the internal of the charge screw through the speed pipe and then goes into the drum after being accele rated Under the centrifugal force, solid particles of big density settle on the inwall of the drun, and form a circular layer of cake, which is continuously pushed by the discharge screw to the small end of the drum 8nd then out of it, while the set:led liquid is continuously discharge out of the drum from the vortex finder of the big end of the drum, hence solid-liquid sparation of suspension.
For the decanter centrifuge, the continuous feeding separating and discharging can be realized as it rotates at its full speed. It is characterized by compact structure easy obturation smith running, low noises, large handing capacity, low energy consumption, high automation small working strength, simple operation and easy maintenance and wide application.
Discharge Decanter Typical Structure
Counter-current type
After blended liquid flows into drum, the cleaned solution and the cake move conversely in separating, each flowing toward its own outlet. The counter current type is a king of normal one and suitable for most separating situations.
Co-current type
After blended liquid flows into drum, the cleaned solution and the cake move in the same direction when separating, after separation, the cleaned solution flows back and is discharged through backfiow connection in order that cake is not washed away by feed liquid when feeding. This rye is more suitable for separation of materials with low concentration and difficult to separate.
Three phase separation type
After two liquid phases and one solid phase with differential density come in to drum, under a centrifugal force, solid phase settles and the two liquid phases are stratified, thus liquid-liquid-solid separation is realized. This type is suitable for such a three-phase separation situation as liquid-liquid-solid with differential density
