Product description
In the field of environmental protection, we use the automatic control system that boasts high length-
diameter ratio, high speed, small differential speed. High length diameter ratio increases the material clarification and dewatering time inside the machine; high speed generates
great centrifugal force, leading to thorough dehydration of material; small differential speed reduces spiral stirring
the materials, increases the dewatering time, therefore improves the separation in sludge thickening, dewatering
and clarification, which can obtain drier solid residue and clearer clarification liquid compared to other decanter c
entrifuges; in order to maintain the best dewatering effect, the operation parameters are subject to automatical re
gulation with the amount and quality of sludge entering into the centrifuge, which ensures normal operation of the
machine and stable water content in the discharged sludge. If the condition of sludge entering the machine
changes greatly, beyond the regulation capacity of the machine or the machine itself fails, the machine will shut
down automatically and alarm.
Our centrifugal sludge dewatering machines can achieve sludge thickening, sludge dewatering as well as
thickening and dewatering integration.
The decanter centrifuge can be adjusted to suit individual requirements by varying:
1. Bowl speed to ensure the exact relative centrifugal force required for optimized separation.
2. Differential speed, for optimized balance between liquid clarity and solids discharge capacity.
3. Pond depth in the bowl for optimized balance between liquid clarity and solid dryness.
Application:
The machine 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, etc.
1. Solid phase dehydration: dehydration effect for processing materials of solid particles.
2. Particle size classification: used in the removal of material of large diameter solid particles.
3. Liquid clarification: used for removing solid particles in the suspension liquid are clarified.
Working principle
Separation takes place in a horizontal cylindrical bowl equipped with a scroll conveyor. The processing material is
fed into the bowl through a stationery inlet tube and is smoothly accelerated in the accelerate chamber.
Centrifugal forces cause instant sedimentation of the solids on the wall of the bowl. The conveyor rotates in the
same direction as the bowl, but at a different speed, thus moving the solids towards the conical end of the bowl.
The process of sludge dewatering :
The sludge dewatering system consists of five parts:
(1) Sludge feeding system, (2) Flocculant dosing system, 3) Thickening and dewatering system,
(4) Mud cake delivery system, (5) Electronic control device of sets of system;
Thickening and dewatering of sludge arising from urban life, power plant, petrochemical refinery, coking as well
as from industries.
