The horizontal spiral centrifuge is mainly composed of a drum, a screw, a differential system, a liquid level baffle, a drive system, and a control system. A decanter centrifuge utilizes the density difference between solid and liquid phases to accelerate the settling velocity of solid particles under the action of centrifugal force, thereby achieving solid-liquid separation. The specific separation process is that the sludge and flocculant solution are sent into the mixing chamber of the drum through the inlet pipeline, where they are mixed and flocculated (if they are added before the sludge pump or after the pump pipeline, the flocculation reaction has been carried out in advance). Due to the high-speed rotation and frictional resistance of the rotor (spiral and drum), the sludge is accelerated inside the rotor and forms a cylindrical liquid ring layer (liquid ring area). Under the action of centrifugal force, solid particles with high specific gravity settle on the inner wall of the drum to form a mud layer (solid ring layer). Then, the relative velocity difference between the spiral and the drum is used to push the solid phase towards the cone end of the drum. After pushing out the liquid surface (shore area or drying area), the sludge is dehydrated and dried, pushed towards the slag discharge outlet, and the supernatant is discharged from the large end of the drum, achieving solid-liquid separation. The sentence is:. With continuous use, you may ask how to improve the efficiency of the horizontal spiral centrifuge?

 

 


1.What is the function and principle of the differential in a horizontal spiral centrifuge? The differential is an important component in a horizontal spiral centrifuge, as it can generate a constant differential speed between the centrifuge screw rod and the drum, enabling smooth solid-liquid separation. The liquid flowing out of the cylindrical outlet can be flushed out of the cylindrical outlet. Therefore, in summary, this conclusion can be drawn.

 

2. An important factor affecting the solid-liquid separation efficiency of a horizontal spiral centrifuge? There are many related factors for the solid-liquid separation effect of a horizontal spiral centrifuge. However, among these related factors, the main ones are the properties of the material, namely the particle size, shape, and density of solid particles in the material, as well as the density, viscosity, and surface tension of the liquid. In addition, the application range of different horizontal spiral centrifuges also depends on the material properties.
