Core Components and Structure
The core component of a rotary drum centrifuge is the centrifugal drum, which is usually cylindrical and may have a spiral or other special design on the inner wall to optimize the separation effect. A centrifuge generally consists of a feed pipe, a centrifugal drum, a discharge pipe, a motor, and a control system. The feed pipe and the discharge pipe are usually located at both ends of the centrifugal drum and can be adjusted as needed.
Working principle
1. Rotation generates centrifugal force: When the motor drives the centrifugal drum to rotate at high speed, the mixture (such as a suspension or emulsion) enters the centrifugal drum through the feed pipe. The components in the mixture begin to separate due to the centrifugal force.
2. Component separation: Under the action of centrifugal force, different components in the mixture are separated to different positions due to their density or size differences. Particles with higher density (such as solid particles) are deposited on the inner wall or bottom of the centrifugal drum under the action of centrifugal force to form a sedimentation layer; while liquid components with lower density are repelled to the top or outside of the centrifugal drum to form a supernatant layer.
3. Discharge of separated materials: The separated components are usually discharged separately through different discharge pipes, thereby achieving effective separation of the mixture.
Factors affecting separation effect
1. Speed: The higher the speed, the better the separation effect is usually. Because the increase in speed will increase the centrifugal force, thereby accelerating the separation of components.
2. Inner wall structure: The inner wall structure of the centrifugal drum also has an important influence on the separation effect. Different inner wall designs can optimize the separation path and separation efficiency of different components.
3. Mixture characteristics: The density, viscosity, particle size and other characteristics of the mixture will also affect the separation effect. Therefore, the specific characteristics of the mixture need to be considered when selecting a centrifuge.
Application fields
Drum centrifuges are widely used in many fields, such as chemical industry, pharmaceutical industry, food industry, environmental protection, etc. They can be used to separate various mixtures, such as separating raw materials and by-products in acetoxalic acid synthesis, or for separation and purification of biological preparations, vaccines, proteins, enzymes, antibodies, etc.
The working principle of the drum centrifuge is to use centrifugal force to separate different components in the mixture. By rotating the centrifugal drum at high speed, the components in the mixture are separated to different positions under the action of centrifugal force and discharged separately through different discharge pipes. This equipment is widely used in many fields and is favored for its efficient separation ability and simple operation.
