Decanter centrifuge is a machine that uses centrifugal force to separate liquid-solid or liquid-liquid mixtures.Through the high-speed centrifugal force come into the high-speed rotating drum, the liquid in the solid-liquid mixture is thrown out of the rotating drum at high speed, and the solid remains in the rotating drum to achieve the effect of solid-liquid separation.
The decanter centrifuge is mainly used to separate the solid grain from the liquid in the mixture; Or to separate two liquids of different densities from each other in the incompatible (for example, to separate cream from milk); It can also be used to remove liquids from wet solids, such as drying wet clothes in a spin dryer; The special overspeed tubular separator can also separate gas mixtures of different densities; Use the characteristics of different density or grans glass of solid gran sedimentation at different rates in the liquid, other decanter centrifuges can also classify solid particles according to density or grans glass.
Centrifuges are widely used in chemical industry, petroleum, food, pharmaceutical, mineral processing, coal, water treatment and shipbuilding and other departments.
In fact, in order to achieve real explosion-proof centrifuges, various measures must be taken in terms of machinery, electronic control, and accessory configuration, such as: electronic control system: explosion-proof isolation grid, non-contact energy-consumption braking system, static electricity, etc. Grounding, explosion-proof automatic control.
Tubular centrifuges are used in liquids with a solid phase content of less than 2% and solid phase particles smaller than 2-5µ. And liquid-solid separation of suspension with small difference in liquid-solid density, and oil-water separation with small difference between light liquid and heavy liquid. The main feature of the tubular centrifuge is high speed, and the speed is generally above 10,000 rpm. Refining equipment, after separation, there is almost no solid content, and the two liquids have very little residue on each other. Manual unloading is required. Manual cleaning. Small output with a flow rate below 50L-1000L/hour.
It is mainly used for liquid-solid separation with a solid content of less than 10% and a solid phase particle diameter greater than 0.5 microns. Often used for oil-water separation: vegetable oil, animal oil, fuel oil; food: fruit juice clarification, yeast extraction, etc.; pharmaceutical industry vaccines, bacteria, glucose extraction, etc.; separation and clarification of traditional Chinese medicine plant extracts.
Applied to the separation of mixed liquid with a solid phase particle size greater than 0.005mm and a concentration range of 2-40%. The equipment is divided into two separations of liquid and liquid, and three separations of liquid, liquid and solid. The equipment is mainly used in chemical industry, food, medicine, environmental protection and so on.
Main feature:High load-bearing strength: The base is a flat-plate structure, which reduces the center of the machine. The machine and the shell are integrally welded, and the load-bearing strength is high.Good shock absorption performance: the machine feet are equipped with liquid damping shock absorption system, which has better shock absorption effect and can be installed without foundation.Large clamshell and small clamshell are optional, and can be equipped with feeding pipe, washing pipe, observation port, and light spray system.The equipment is directly connected to the motor, which effectively prevents the dust brought by the belt drive. Frequency conversion start: stable start, energy saving and safety.The equipment has good sealing performance and can meet the explosion-proof requirements. Suitable for flammable and explosive places.Application range:It is suitable for materials with a moisture content of more than 50%. It is suitable for both particle filtration and fiber material dehydration.
Our factory covers an area of 500000m2. The lush green area of the factories and modern equipment of the plants show the new sign of Chinese manufacturing industry.
