Screw Conveyor

Product description

U-shaped screw conveyor is a common type in the screw conveyor family. Its chute has a U-shaped structure, a design feature that gives it a unique advantage. During operation, the built-in spiral blade rotates at a high speed, and the material is moved in the U-shaped slot by means of the spiral propulsion force to complete the conveying operation.

Compared with other conveying equipment, U-screw conveyor has compact structure, small space, and can flexibly adapt to various production sites. The sealing property of U-shaped groove is good, which can effectively avoid material leakage, reduce dust publicity, not only ensure the integrity of material transportation, but also meet the environmental protection requirements, especially suitable for conveying all kinds of powder, granular and small block materials, such as chemical raw materials, cement, grains, etc. Moreover, it can realize multi-point feeding and discharging, smooth conveying process, little damage to materials, and plays a key role in many industries such as chemical industry, building materials, and food processing.

Working principle

The working principle of the U-shaped screw conveyor is to use the rotating spiral blade to push the material in the U-shaped groove.

The motor drives the spiral shaft to rotate through the reducer, and the spiral blades on the spiral shaft rotate accordingly. When the spiral blade rotates, the material is subjected to the normal thrust and friction of the blade. The normal thrust makes the material produce a component force along the axis of the spiral axis, thus pushing the material to move forward in the U-shaped groove; The friction force drives the material to rotate with the spiral blade, but due to the constraints of the U-shaped groove wall, the rotational movement of the material is limited, mainly manifested as the linear movement along the axis of the groove body, so as to achieve the conveying of the material. In this process, the U-shaped groove plays a role in containing and confining the material, ensuring that the material is stably transported in the predetermined direction.

Product characteristics

1. Clever structural design: U-shaped groove structure makes the equipment compact, occupies small space, and can adapt to different installation environments, especially in places with limited space, such as some small factory workshops or warehouses, and its advantages are more obvious.

2. Good sealing: U-shaped groove is equipped with sealed cover plate, which can effectively prevent material leakage and dust flying, which not only reduces material waste, but also improves the working environment, in line with environmental protection and health requirements, especially suitable for industries with high environmental cleanliness requirements, such as food, medicine and other fields.

3. High conveying efficiency: the design of spiral blades can be optimized according to material characteristics and conveying requirements, which can achieve higher conveying capacity, and can achieve horizontal, inclined and even vertical conveying to a certain extent, and the conveying Angle is flexible and changeable to meet the needs of different production processes.

4. Easy maintenance: the equipment structure is relatively simple, the main components are few, the wearing parts such as spiral shaft and spiral blade are easy to replace, the daily maintenance workload is small, reducing the maintenance cost and downtime, and helping to improve production efficiency.

5. Wide range of application: can transport a variety of powder, granular and small block materials, such as cement, pulverized coal, grain, sand, etc., strong adaptability to materials, in chemical, building materials, grain, metallurgy and other industries have a wide range of applications.

6.Easy installation: The overall structure of the equipment is compact, covers a small area, and can be flexibly installed in the limited space of the working environment, without the need for a large area of installation space, providing more convenience for the enterprise site planning.
