Definition and classification
Horizontal screw centrifuge, also known as horizontal spiral sedimentation centrifuge, is a highly efficient centrifugal separation equipment. It can generally be divided into two types: horizontal spiral filtration centrifuge and horizontal spiral sedimentation centrifuge. This type of equipment is widely used in the field of solid-liquid separation. With its compact structure, continuous operation, stable operation and other characteristics, it occupies an important position in many industries. Efficient, reliable, and versatile.
The horizontal screw centrifuge is a vital tool for solid-liquid separation. Thanks to its compact design and consistent performance, this equipment has become a staple in many industries. Whether used for horizontal spiral filtration or sedimentation, this centrifuge offers unparalleled efficiency and reliability.
Working Principle
The working principle of the horizontal spiral centrifuge is based on the mechanism that the drum and the spiral run at high speed in the same direction with a certain differential speed. The material enters the inner cylinder of the feed spiral continuously from the feed pipe, and then is accelerated into the drum. Under the action of the centripetal force field, the heavier solid phase accumulates on the inner wall of the drum to form a slag layer, and the lighter liquid phase forms an inner liquid ring. The feed spiral continuously pushes the accumulated solid phase to the cone end of the drum and discharges it through the slag discharge port; at the same time, the liquid phase continuously overflows from the overflow port at the large end of the drum and is discharged through the liquid discharge port.
The whole process realizes continuous feeding, separation, cleaning and dumping at full speed. It is a scientifically designed centrifuge that continuously feeds, separates, cleans and processes materials at the highest speed. Its working principle is a high-speed drum and spiral rotating in the same direction, using the centripetal force field to achieve solid-liquid separation, with a liquid ring and a residue layer inside, and the efficiency of this technology is unparalleled.
Application fields
Decanter centrifuges are widely used in chemical industry, light industry, pharmaceutical industry, food, environmental protection and other fields. In the chemical industry, decanter centrifuges are used to separate liquids and solid particles; in the light industry, it is often used for washing, grading and dehydrating starch; in the pharmaceutical industry, it is used for separation and purification of biological drugs; in the food industry, it is used for dehydration of soybean and wheat proteins, as well as purification of fruit juice.
In addition, in the field of environmental protection, decanter centrifuges play an important role in the separation and dehydration of industrial and domestic sewage, which helps to improve water quality. Decanter centrifuges are used in a variety of industries such as chemical, light industry, pharmaceutical, food and environmental protection, and have many advantages. They can efficiently and effectively separate liquids from solid particles, wash and grade starch, purify biopharmaceuticals, dehydrate proteins, and help improve water quality. Due to their versatility and precision, they are an indispensable tool for ensuring quality and efficiency in a wide range of applications.
Advantages and Disadvantages
Advantages:
- Large processing capacity: It has the characteristics of continuous operation and low unit power consumption. It is suitable for the separation of suspensions with difficult filter cloth regeneration and large concentration and particle size variation range.
- Stable operation: The horizontal design allows the machine to maintain balance at high speed and reduce vibration and noise.
- Compact structure: It occupies a small area and is easy to install and use.
- High safety performance: It is equipped with a variety of safety measures, such as overload protection and emergency shutdown devices.
Disadvantages:
- Unstable separation effect: Due to the different composition and properties of the materials, the separation effect may be unstable.
- High maintenance cost: The structure is relatively complex and requires regular maintenance and upkeep.
- Noise problem: Although the design has minimized noise, some noise will still be generated during operation.
Operating procedures and maintenance
Operating procedures:
- The operator must be familiar with the structure, performance and operation methods of the equipment.
- Before operation, check the equipment status to ensure that all parts are intact.
- Wear personal protective equipment during operation and comply with safety regulations.
- Repair, cleaning and adjustment are prohibited during operation.
- Before stopping, wait until the equipment stops completely before proceeding to the next step.
Maintenance:
- Ensure that the equipment installation surface is flat and firm, and regularly check and adjust the anchor screws to ensure the level of the entire machine.
- Lubricate the lubricating parts of the equipment and add appropriate grease or lubricant as required.
- Check the tightness and wear of the belt regularly, and adjust or replace it in time.
- Check carefully before separating the material to avoid metal objects or large solids entering the equipment and causing damage.
- When the equipment is not used for a long time, it needs to be cleaned and the clear liquid in the drum needs to be emptied, and it needs to be powered on and started regularly to ensure normal use next time.
