Horizontal spiral centrifuge is a type of spiral discharge settling centrifuge that plays an important role in multiple industries, especially in achieving solid-liquid separation. The following is an introduction to the horizontal spiral centrifuge:

1、 Working principle

The horizontal spiral centrifuge is mainly composed of a high-speed drum, a screw conveyor with a hollow shaft that rotates in the same direction as the drum but at a slightly lower speed, and a differential. Its working principle is that when the suspension to be separated is sent into the rotary drum through a hollow shaft, it is immediately thrown into the drum cavity under the centrifugal force generated by high-speed rotation. The high-speed rotating drum generates strong centrifugal force, which throws solid particles with higher density than the liquid phase onto the inner wall of the drum, forming a solid layer (solid ring layer). Due to its low density and centrifugal force, water forms a liquid layer inside the solid ring layer, known as the head liquid ring layer. By utilizing the relative motion (i.e. speed difference) between the spiral and the drum, the sludge in the solid ring layer is slowly pushed to the cone end of the drum and discharged after passing through the drying zone. The liquid in the liquid ring layer is then discharged outside the drum by gravity, forming a separation liquid.

2、 Characteristics

1. Compact structure: The whole machine adopts an integral frame structure, which is safe and convenient to lift, and occupies a small area.

2. Continuous operation: capable of continuous feeding separation, washing, and unloading at full speed.

3. Smooth operation: Adopting involute planetary gear differential for high transmission ratio and precision; The main motor with power frequency speed regulation is equipped with a hydraulic coupling, ensuring smooth operation of the motor.

4. Strong adaptability: Suitable for separating suspensions containing solid particles with a particle size greater than 0.005mm and a concentration range of 2-40%.

5. High safety: The whole machine is equipped with dual overload protection devices for mechanical and electrical equipment, ensuring safe use. The explosion-proof level of power frequency and variable frequency electrical equipment is high, and the sealing performance of the control box is good,

3、 Application Fields

Horizontal spiral centrifuges are widely used in industries such as chemical, light industry, pharmaceutical, food, and environmental protection. In the chemical industry, it is used to separate liquid and solid particles, such as separating solid particles from suspensions in chemical processes and removing impurities from waste liquids. In light industry, it is used for the washing, grading, and dehydration processes of starch. In the pharmaceutical industry, it is used for the separation and purification process of biopharmaceuticals. In the food industry, it is used for dehydration of soy and wheat proteins, dehydration of fish meal and meat, dehydration of wine tanks, purification of fruit juice, and dehydration of fruit pulp fibers. In the environmental protection industry, it plays an important role in the separation and dehydration of industrial and domestic wastewater, helping to reduce the solid content in wastewater and improve water quality.

4、 Selection

Choosing the appropriate horizontal spiral centrifuge is of great significance for solving production problems, improving work efficiency, saving production costs, and reducing business risks. When selecting, factors such as material properties, processing capacity, solid particle size, concentration range, etc. need to be considered to ensure the normal operation and optimal performance of the equipment.
