China Horizontal Spiral Sedimentation Continuous Decanter Centrifuge Machine

Product Description

Description :
LW Sedimentation Centrifuge is a horizontal, continuously working and continuously spiral discharging sedimentation centrifuge. It is used in a variety or industries for separating all kinds of solid liquid suspension, defecating liquid phase with graded grains, and dehydrating sludge.
2 phase Decanter Centrifuge:
After entering into the high-speed turning drum, the solid-phase particles in the mixed liquid run and settle on the drum wallunder the action of greatest centrifugal
force; the light liquid settles at the innermost place of the drum under minimum centrifugal force; same as the drum's turning direction, a screw feeder also turns at a
high speed, and a constant speed difference is generated by the differential mechanism, then the liquid will be discharged by the liquid outlet.
3 phase Decanter Centrifuge:
Principle of threephase decanter centrifuges is as shown in the above figure. The substance to be separated is fed by the feeding tube into the accelerating cavity of

the spiral conveyor, then enters high speed running drum wall. As the light liquid, heavy liquid and insoluble solid contained in the substance have different specific
gravities, the three materials are subject to varied centrifugal forces: the insoluble solid settles into the inner wall (outside) due to its highest specific gravity and subject
to maximum centrifugal force; the light liquid settles maximum far away from the inner wall (outside) due to its lowest specific gravity and subject to minimum centrifugal
force; and heavy liquid settles in the middle place. The insoluble solid is discharged from the solid discharge port by a spiral feeder which has relative differential speed

with the drum; and the light and heavy liquids are then separated by different structures inside the machine wherein the heavy liquid is discharged by the centripetal
pump, and the light liquid is discharged via the force of gravity, thus the purpose of three phase separation is achieved.
Feature:
The decanter centrifuge can be adjusted to suit individual requirements by varying:
1.Differential with high precision, compact structure, smooth operation.
2.Main bearing of imported bearings, to ensure the accuracy of the operation.
3.The part contacting with material is made of stainless steel.
4.The machine is equipped with a variety of safety overload protection devices, to make sure safety in production.
5.The machine system has two types, regular and explosion proof, to meet the different requirement.
6.Large length to diameter ratio, high speed, many angels of drum cone structure
7.Spiral pusher surface adopts hard alloy materials, against abrasion powerfully
8.According to the customer's desire, the frame can develop to low center of gravity, high bracket and move.
9.Spiral structure with BD board is used for the concentration dehydration of activated sludge and difficult separate materials
10.PLC control box
Application:
1.Environmental protection city life of dirt, power plants, petrochemical refinery sludge sludge, coking, industrial sludge concentration, sludge dewatering.
2.Food and drink fruit juice slag, slag of animal oil, plant oil, soy protein isolates of dehydration, concentration of fish protein, wheat starch B dehydration.
3.Chemical * barium dehydration, kaolin industry classification and grade of graphite and PPT, classification of drilling mud.
4.Coal tar, coal tar dehydration and slag, adapted to the different viscosity and water (emulsion) of coal tar separation, after the separation of reach national standard tar.
5, oil separation, vegetable oil, like avocado oil, olive oil, sesame oil, soy oil and so on.
animal oil, pork oil, fish oil, chiecken oil, beef oil ect.
waste oil like the waste heavy oil, fuel oil, other waste oil.
