Scroll discharge decanter centrifuge for washing and dehydration of
starch
Introduction
Centrifugal sedimentation is the working principle of this
centrifuge, it can separate two phases (suspended solid liquid and
liquid) or three phases (solid-liquid-liquid), solid phase is
pushed out by spiral continually; this equipment is a constant and
high effective equipment which used in separating solid-liquid.
Working principle
Centrifuge is consist of two rotors, one is drum the other is screw
conveyor ( For short spiral). Drum running with High-speed, the
drum and slurry will rotate together and by the centrifugal force
effect, this centrifugal force is larger than the weight many
times, so that solid particles will be separated from the liquid,
from the drum axis, then setting on the drum wall, the screw
conveyor which located in the drum and rotating at the speed which
lower than the speed of drum then push the solid particles to the
residue discharge port. Difference speed between outside drum and
screw conveyor depends on the speed of the transmission ratio of
differential and its rotation speed. The two phases with different
densities form concentric cylinders, with the lighter liquid in the
inner layer and the heavier liquid in the outer layer and
discharged through the outlet of the light and heavy phases
respectively.

Product structure
Drum: The cylindrical - conical cylindrical rotor is composed of a
cone and a cylinder. The aim for designing this shape is to obtain
a better separation performance. When drum rotating at high-speed,
it will drive slurry rotate, and under the centrifugal force, the
heavier solid particles will be separated from the liquid.
Cylindrical drum part is to facilitate the clarification of the
filtrate (centrifuge), and conical part is conducive to dehydrate
the solid material.
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 thegood
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.
