Adaptability to viscous materials
1. Viscosity range:
When the disc centrifuge processes viscous materials, the viscosity of the materials needs to be controlled within a certain range.
Excessive viscosity will increase the flow resistance of the materials between the discs and affect the separation effect.
Generally speaking, disc centrifuges are more suitable for processing low and medium viscosity materials. For high viscosity materials, pretreatment measures such as dilution and heating may be required to reduce their viscosity.
2. Fluidity:
Viscous materials should maintain good fluidity so that they can smoothly enter the drum of the disc centrifuge and be separated through the disc gap. If the material has poor fluidity, it may cause blockage of the feed pipe or the disc gap, affecting the normal operation of the equipment.
Requirements for operating conditions
1. Temperature control:
For viscous materials, proper temperature control can improve their fluidity, reduce viscosity, and thus improve the separation effect.
When operating a disc centrifuge, the operating temperature should be adjusted according to the characteristics of the material to ensure that the material maintains good fluidity in the drum.
2. Speed adjustment:
The speed of the disc centrifuge has an important influence on the separation effect. For sticky materials, the appropriate speed can balance the interaction between centrifugal force and material viscosity and improve separation efficiency.
In actual operation, the appropriate speed should be selected for separation based on the material’s characteristics such as viscosity and density.
Requirements for pretreatment
1. Dilution:
For high viscosity materials, dilution can be used to reduce their viscosity and improve fluidity. The choice of diluent should be determined according to the chemical properties of the material and the separation requirements.
2. Heating:
Heating can reduce the viscosity of the material and improve its fluidity. However, care should be taken to avoid excessively high temperatures that may cause the material to denature or decompose.
3. Filtration:
Before entering the disc centrifuge, filtering the viscous material can remove large particles of impurities and prevent clogging of the disc gap.
Requirements for equipment maintenance
1. Regular cleaning:
Since viscous materials are easy to adhere to the disc and drum, the disc centrifuge needs to be cleaned regularly to maintain its good separation effect.
2. Inspection and maintenance:
Regularly check the wear of the feed pipe, disc, drum and other components of the disc centrifuge, and replace damaged components in time to ensure the normal operation of the equipment.
