Product Description

DESCRIPTIONS:

 

Horizontal screw decanter centrifuge is a kind of horizontal screw unloading, continuous operation settlement equipment. The working principle of this type of centrifuge is: the drum and the screw rotate at a certain differential speed in the same direction and at a high speed, the raw material is continuously introduced into the inner drum of the conveying screw by the feeding pipe, and enters the drum after acceleration. Under the action of the centrifugal force field, the heavier solid phase deposits on the drum wall to form the sediment layer. The conveying screw continuously pushes the deposited solids to the cone end of the drum, and then discharges them out of the machine through the slag discharge port. The lighter liquid phase forms an inner liquid ring, which overflows the drum continuously from the overflow port at the big end of the drum, and is discharged out of the machine through the discharge port. The machine can continuously feed, separate, wash and discharge materials at full speed. It is characterized by compact structure, continuous operation, stable operation, strong adaptability, large production capacity and convenient maintenance. It is suitable for the separation of suspension with solid particle size greater than 0.005mm and concentration range of 2-40%.

The larger the solid particles in the material, the easier it is to separate. The size of the solid particles varies, and the final separation effect is determined by the small particle solid phase. This machine can generally remove solid particles above 5 um. When the solid particles are especially small, they will not settle and separate out, but will be discharged together with the clarified liquid; The final separation effect depends on the distribution of solid particles in the material. The more particles above 5 um, the better the separation effect; On the contrary, the separation effect is worse.

 

Generally, crystalline solids and fibrous solids are easier to separate, while flocs and paste solids are more difficult to separate. Due to the large maximum water solubility of flocs and paste solids, when spirally pushing sediment, it is easy to slip and affect the separation effect, so the flow rate should not be too large when separating flocs and paste solids.

 

The greater the weight difference between the solid phase and the liquid phase, the better the separation, and vice versa, the worse the separation effect The lower the liquid viscosity, the easier it is to separate. When the liquid viscosity is higher, the solids entrained in the clarified liquid increase, and the separation effect becomes worse. At this time, the material temperature can be increased and the viscosity can be reduced to improve the separation effect (the maximum feed temperature is not greater than 95 ºC).

 

Selection Of Feed Flow (I.E., Processing Capacity)

 

From a separation perspective, the smaller the feed flow rate, the smaller the axial flow rate of the material in the drum, the longer the residence time of the material in the drum, and the better the separation effect. As the feed volume increases, the axial flow rate increases, and the retention time of the material in the drum decreases. The separation effect becomes worse.

 

The feed volume of the centrifuge is also limited by the maximum slag removal capacity of the spiral. If the feed volume is too large, the separated sediment will not be discharged in a timely manner, resulting in blockage of the drum.

 

Therefore, when using the centrifuge, the appropriate feed flow rate should be selected based on the material characteristics, separation requirements, and the solid content of the material, Generally, when the solid content is large, the feed rate should not be too large. The appropriate feed rate can be determined after comparing the separation effects of various flows. Generally, it is recommended that the flow rate should not be too large for materials that are difficult to separate, and the flow rate for materials that are easy to separate can be larger. However, attention should be paid to the maximum slag discharge amount of the spiral, otherwise it will cause material blockage
