In industrial production, liquid-solid separation is a vital link. Whether in the fields of chemical, pharmaceutical, food or environmental protection, efficient and reliable liquid-solid separation equipment is needed to ensure the smooth production process and stable product quality. As an advanced liquid-solid separation equipment, the tubular centrifuge has become a multifunctional solution to this problem with its unique working principle and wide application field.
Working principle of tubular centrifuge
The tubular centrifuge drives the drum to rotate around the main axis at high speed through a motor. Under the action of the centrifugal field, the liquid and solid particles are separated according to their different specific gravity. In the drum, the material is subjected to a strong centrifugal force, so that the solid particles with higher density are thrown to the inner wall of the drum to form a solid layer; while the liquid with lower density is located on the outside of the solid layer to form a liquid layer. As the drum continues to rotate, the solid particles are continuously pushed to the conical end of the drum and finally discharged through the slag discharge port; while the liquid overflows through the overflow hole at the large end of the drum, thereby achieving liquid-solid separation.
Versatility of tubular centrifuges
1. Wide range of applications:
Chemical industry: used for oil-water separation, purification and concentration of chemicals, etc.
Pharmaceutical industry: used for separation, purification and concentration of biological products, as well as clarification of Chinese medicine oral liquids, etc.
Food industry: used for clarification and separation of juices, alcoholic beverages, dairy products, etc.
Environmental protection industry: used for sewage treatment, sludge dehydration, etc.
2. Handling difficult-to-separate emulsions:
Tubular centrifuges are particularly suitable for liquid-liquid separation with very small density difference between the two phases (specific gravity difference greater than 0.1%), and liquid-liquid-solid three-phase separation containing a small amount of impurities.
This versatility gives tubular centrifuges significant advantages in handling complex materials.
3. Efficient separation effect:
Due to the use of high-speed rotation and a strong centrifugal field, tubular centrifuges can achieve efficient liquid-solid separation. It has strong separation ability and high liquid clarity, which can meet the high requirements of different industries for product quality and production efficiency.
4. Flexible operation mode:
The tubular centrifuge can be flexibly operated and adjusted according to actual production needs. For example, particles of different sizes can be gradually separated by adjusting the centrifugal speed and time to achieve differential centrifugation; and the processing needs of different materials can be adapted by replacing the drum and liquid collecting parts of different specifications.
As an advanced liquid-solid separation equipment, tubular centrifuge has become a multifunctional solution to the liquid-solid separation problem with its unique working principle and wide application field. In the future development, with the continuous advancement of technology and the continuous expansion of application fields, tubular centrifuge will usher in a broader development prospect. At the same time, it is also necessary to continuously strengthen the research on separation theory and the optimization of centrifugal separation process to improve the separation performance and stability of tubular centrifuge and meet the needs of different industries for high-quality products and efficient production.
