The equipment that uses centrifugal force to separate solids and liquids based on their different specific gravity is Industrial Centrifuge. This equipment is widely used in the chemical and pharmaceutical industries and is a key unit operation device in chemical industry, with widespread applications in the chemical and pharmaceutical fields. A centrifuge is a device that separates solids and liquids by centrifugation. Due to the special nature of centrifuges, their level of automation and discharge methods often determine the advancedness of the entire production process and the layout of the factory. The technical status of international industrial centrifuges is classified according to the unloading method below.
Three-legged centrifuge machine
The three-legged centrifuge is one of the most traditional and common industrial centrifuges, and is also the most widely used centrifuge in the production process of raw materials. Its features are: manual loading and unloading and cleaning, strong production flexibility and high labor intensity; simple structure, easy to operate and maintain; high universality, wide applicability, suitable for separating particle-like solid phases of suspensions and fibrous solid materials; crystalized solid phase should not be broken; when operating intermittently, the yield of each batch of solids should not be too large.
Plate centrifuge machine
The plate centrifuge is an upgraded version of the three-legged centrifuge. In addition to the characteristics of the three-legged centrifuge, the plate centrifuge is equipped with damping shock absorbers on the base, making it more convenient and flexible to install and maintain.
Horizontal scraper centrifuge machine
So far, the horizontal scraper centrifuge is an advanced centrifugal separation device mainly used for material separation in clean areas. Since its introduction, it has been recognized by a wide range of users and now represents an advanced production mode.
Working principles of the horizontal scraper centrifuge machine
When the rotating drum operates at high speed, the material enters the drum through the feeding tube and the blade ejects the liquid and debris onto the drum wall. The liquid will be filtered out through the filter under the action of centrifugal force and will be ejected onto the outer shell, and finally discharged from the drainage pipe of the chassis. What remains is the filter cake. When the thickness of the filter cake reaches the maximum volume of the equipment, close the feed valve, the horizontal scraper centrifuge begins to rotate at high speed, accelerating to the rate of liquid removal, and begins the dewatering operation. When the drainage pipe no longer has liquid flowing out, the material will be dried and then the scraper unloading operation will begin, scraping the material off. Thus, the entire process is completed.
The horizontal scraper centrifuge is equipped with a horizontal scraper, which can be automatically loaded and unloaded with low labor intensity, has a fully enclosed and clean structural design that meets good production standards and sterile production requirements, adopts PLC control with high automation level, easy to operate and maintain, can achieve CIP and SIP functions. The zoning design can effectively save the cleaning area inside the factory, and is equipped with a gas backflush device to assist the scraper to be installed perpendicular to the drum and scraper, the structure is relatively simple, can be used for non-fully enclosed design, has a wide range of applications, can be used in clean areas as well as non-clean areas, and can be designed semi-automatically and flexibly operated, suitable for batch production, laboratory enlargement stage and small batch production.
