Screw Conveyor

Product description
Vertical screw elevator is a kind of continuous conveying equipment for vertical conveying materials. It is mainly composed of a drive device, spiral body, chute, feed port and discharge port, etc. The drive device drives the spiral body to rotate in the chute, and uses the spiral blade to push the material to lift the material from a lower position to a higher position, which can be used to lift granular, powdered and other loose materials, such as grain, cement, sand, etc. It is widely used in many industries such as chemical industry, building materials and grain processing. It has the advantages of simple structure, small footprint, good sealing and high conveying efficiency, which can effectively save space and manpower and achieve efficient vertical conveying of materials, but there are also certain requirements for material particle size and viscosity, and the helix is easy to wear and other limitations.

Working principle
Vertical screw elevator relies on screw propulsion and friction transmission to achieve vertical material transportation. The core part of the spiral body is composed of spiral blades and a central shaft. The driving device drives the central shaft to rotate, and the spiral blades run accordingly. The material falls into the chute from the feed port and is placed on the spiral blade. When the spiral blade rotates, the material is pushed along the direction of the spiral line. The vertical component of this thrust will gradually lift the material upward, while the horizontal component will prevent the material from scattering. At the same time, the friction between the material and the spiral blade and the inner wall of the groove drives the material to move, prevents it from sliding, and helps the material to rise steadily. For materials with large viscosity or poor fluidity, the internal friction between materials can also be used to drive the surrounding materials through the internal friction of some materials driven by the spiral blade to achieve the overall improvement.
 
Product characteristics

1. Compact structure: the overall structure of the vertical screw elevator is relatively simple, mainly composed of the basic components such as the drive device, the screw body, the chute and so on, there is no complex intermediate transmission mechanism and a large number of ancillary equipment, the space is small, and the material can be vertically lifted in a limited space, especially suitable for use in places with narrow space, such as some small factories, workshops and so on.

2. Good sealing: it usually uses a closed tank and spiral design, and the material is isolated from the external environment during the conveying process, effectively preventing the leakage, flying and dust pollution of the material, not only to ensure the quality of the material, but also to improve the working environment, suitable for conveying some dust, toxic or corrosive materials.

3. Flexible conveying direction: Just change the rotation direction of the helix, you can easily achieve the upward and downward conveying of the material, according to different process and production needs, flexibly adjust the direction of the material, providing more flexibility for the design of the production layout and process.

4. High conveying efficiency: within a certain conveying capacity range, the vertical screw elevator can maintain a high conveying speed, and can continuously improve materials, which can meet the requirements of fast and efficient conveying of materials in most production scenarios, and help improve production efficiency.

5. Low maintenance cost: Due to its relatively simple structure and small number of parts, the daily maintenance work is more convenient and the maintenance cost is relatively low.
