Horizontal Spiral Unloading Filter, Sea Salt Centrifuge Propeller

 

Equipment Overview

 

The propeller of the sea salt centrifuge combines the principles of centrifugal sedimentation and spiral propulsion. The centrifugal force generated by high-speed rotation separates the salt in the seawater from other impurities, and realizes continuous salt discharge through the spiral propeller. This equipment has the characteristics of large processing capacity, high separation efficiency, high degree of automation, and stable operation. It is one of the key equipment in the sea salt production process.

 

Working Principle

 

The working principle of the propeller of the sea salt centrifuge is mainly based on the following steps:

• Feeding : Seawater continuously enters the drum of the centrifuge through a special feeding device.
• Centrifugal separation: The drum generates a strong centrifugal force under high-speed rotation, so that the salt in the seawater is quickly deposited on the inner wall of the drum to form a salt layer. At the same time, other liquid components in the seawater are thrown outward and discharged through a specific discharge port.
• Spiral propulsion: The spiral propeller in the drum rotates in the same direction as the drum at a slower speed, continuously pushing the deposited salt particles to the discharge end. In this process, the spiral propeller also plays a certain stirring and crushing role, which helps to evenly distribute and further separate the salt particles.
• Continuous salt discharge: When the salt particles are pushed to the discharge end, continuous salt discharge is achieved through a specific salt discharge device. The discharged salt particles can be obtained after subsequent treatment to obtain finished sea salt.

 

Structural composition

 

• Drum: The core component, which is equipped with a filter or screen for solid-liquid separation. The high-speed rotation of the drum is the key to generating centrifugal force.
• Spiral propeller: Located inside the drum, it pushes the deposited salt particles to the discharge end through its rotation. The design and speed of the spiral propeller have an important influence on the separation effect and salt discharge efficiency.
• Transmission system: It includes motors, reducers, transmission devices, etc., which provide rotational power for the drum and spiral propeller. The stability and efficiency of the transmission system directly affect the overall performance of the equipment.
• Feeding device and drainage device: used to control the feeding of seawater and the discharge of separated liquid respectively. The design of these devices needs to ensure that the feeding is uniform and stable and the drainage is smooth and unobstructed.
• Control system: realize the automatic monitoring and adjustment of the operation of the centrifuge, including the setting and adjustment of parameters such as speed and feed amount. The intelligence of the control system is of great significance to improving the production efficiency of the equipment and reducing the operating cost.
