Product description

Lws355x1460 three-phase centrifugeis that two liquid phases and one solid phase enter the centrifuge and expand it thousands of times by relying on the centrifugal force field. The solid phase is settled under the action of centrifugal force, and the two liquid phases are also stratified, so as to realize Solid-liquid-liquid 3-phase separation and discharge them from the body under the action of special mechanism. The whole feeding and separation process is continuous, closed and automatic.


At present, three-phase horizontal screw centrifuges are widely used in chemical industry, light industry, medicine, food, papermaking, mining and other industries. And coal tar industry; Petrochemical industry; Fishing powder industry, swill oil industry, electrolytic copper industry, and the separation of oil, water and slag from waste residues in slaughterhouses.

Material concentration: the material is required to have good fluidity, subject to not affecting the feed. The weight percentage of mixed liquid and solid concentration is generally ≤ 20% (good fluidity, which can be relaxed appropriately).

Material temperature: the allowable material temperature of this centrifuge is ≤ 900C.

Separation range

A. When the liquid viscosity is small and the solid particle size is large, the specific gravity difference between solid, liquid and liquid is required to be ≥ 0.05g/cm3 (solid weight and liquid light).

B. When the liquid viscosity is small and the specific gravity difference between solid and liquid is large (specific gravity difference ≥ 1g / cm3), the solid particle is required to be ≥ 0.005mm and the specific gravity difference between liquid and liquid is required to be ≥ 0.05g/cm3.

C. When the liquid viscosity is large or the specific gravity of solid-liquid is small and the solid particles are very fine, the separation effect will be affected or even not applicable.

D. When the solid particles are easy to be damaged, the separation effect will also be affected.

Structure and working principle

In the three-phase horizontal screw centrifuge, the materials to be separated enter the acceleration chamber of the screw pusher through the feed pipe and then enter the inner wall of the rotating drum at high speed. Due to the different specific gravity of light liquid phase heavy liquid phase insoluble solid phase in the materials, the centrifugal force on the three-phase materials is different, and the insoluble solid phase is settled to the inner wall (outermost) due to the largest centrifuge with the largest specific gravity, Due to the minimum centrifugal force, the light liquid phase is settled farthest (outermost) from the inner wall of the drum. The heavy liquid phase is in the middle. The insoluble solid phase is discharged from the solid phase outlet through the screw pusher with relative differential speed with the drum. The light and heavy liquid phases are separated by different structures in the machine. The heavy liquid phase is discharged through the centripetal pump and the light liquid phase is discharged by gravity, so as to achieve the purpose of three-phase separation of materials. The light and heavy liquid phases of our three-phase horizontal screw centrifuges are discharged by gravity and centrifugal force respectively, so as to effectively avoid the incomplete separation of materials caused by the mixing of materials. When working, the ordinary three-phase horizontal screw centrifuges often cause incomplete separation due to the unstable components of light and heavy liquid phases, Our three-phase horizontal screw centrifuge can adjust the interface of light and heavy liquid phases according to the changes of material components, so as to achieve the ideal separation effect.

Technical parameter

Users can reasonably select the working parameters of the centrifuge according to the physical properties of the separated material (suspension), separation requirements, treatment capacity, process requirements and other factors, so as to obtain satisfactory separation effect and economic benefits. Colors and materials can be customized.
