Vacuum centrifuge is a kind of equipment for efficient separation of liquid and solid particles, which has a wide range of applications. It separates the solids and liquids in the mixture by creating a centrifugal force and negative pressure environment of high speed rotation. Vacuum centrifuges play an important role in chemical, pharmaceutical, food, environmental protection and other fields. This paper will introduce the principle, application and important role of vacuum centrifuge in the separation process.
The separation principle of vacuum centrifuge is based on the action of centrifugal force and negative pressure environment. Its working process can be roughly divided into the following steps:
1. Loading: The mixture to be separated is injected into the centrifugal chamber of the vacuum centrifuge through the feed port.
2. Rotation: Start the centrifuge to rotate the centrifugal chamber at high speed. The centrifugal force generated by rotation causes solid particles to accumulate in the centrifugal chamber and deposit on the wall of the centrifugal chamber.
3. Separation: The solid-liquid mixture formed in the centrifugal chamber, through the role of centrifugal force, the solid particles are quickly separated out, and the liquid is discharged through the discharge port.
4. Vacuum extraction: Through the extraction device, the centrifugal chamber to establish a negative pressure environment. Under the action of negative pressure, the solid particles dry, and the liquid can be more evaporated or volatilized.
Vacuum centrifuges are widely used in various industries. Here are a few typical application areas:
Vacuum centrifuge is widely used in the field of chemical industry, such as dehydration of organic solvents, solvent recovery and crystal extraction. It can efficiently separate solvents and products, and realize the recycling of resources. In the pharmaceutical field, it is mainly used to concentrate, dehydrate and dry pharmaceutical raw materials, intermediates and end products. It can separate the water and impurities in the drug solution and improve the purity and stability of the drug. It is often used in the food industry for the concentration and dehydration of juices, alcohol, soy sauce and other liquids. By separating the moisture and impurities in the liquid, the concentration and quality of the product are improved, and the shelf life is extended. In the field of environmental protection, it is used to treat wastewater and waste liquid. Through the rapid separation of solid particles and liquids, the volume of waste liquid is reduced, the processing cost is reduced, and the purpose of environmental protection and resource recovery is achieved.
Vacuum centrifuges play an important role in the separation process, which has the following important significance:
1. Efficient separation: Vacuum centrifuges achieve a fast and efficient separation process by creating a high-speed rotating centrifugal force and negative pressure environment. It can quickly separate the solid and liquid in the mixture in a short time, improving production efficiency.
2. Optimize product quality: vacuum centrifuge can effectively remove impurities, moisture and harmful substances in the solution, and improve the purity and quality of the product. This is important for industries such as chemicals, pharmaceuticals and food.
3. Resource recovery and utilization: Vacuum centrifuge can realize the recovery and utilization of resources such as solvents and water, and reduce production costs. Through recycling, not only resources are saved, but also environmental pollution is reduced.
