Description

Technical Field

[0002] Liquid medicine centrifugation is a commonly used separation technology, mainly used in the pharmaceutical industry. The centrifugal force field generated by the high-speed rotation of the centrifuge is used to separate solids and liquids in the liquid medicine, or two immiscible liquids with different densities. Tubular centrifuges are particularly common in liquid medicine centrifugation. Their operating principle is that the centrifuge has a cylinder (called a drum) that rotates at high speed around its own axis, usually driven by an electric motor. After the suspension (or emulsion) is added to the drum, it is quickly driven to rotate at the same speed as the drum. Under the action of centrifugal force, the various components are separated and discharged separately. The higher the drum speed, the better the separation effect. However, cleaning the filter pulp of the tubular centrifuge each time is troublesome, requiring a large amount of cleaning water, and the cleaning effect is often poor. Large pieces of residue are more serious, resulting in the need for auxiliary manual cleaning after long-term use. Utility Model Content
