一. Overview of Pipe Chain Conveyor

Pipe chain conveyor is a continuous conveying equipment for conveying bulk materials such as powder, small granular and small blocks. It can be conveyed horizontally, inclined and vertically in combination. In a closed pipeline, the chain is used as the transmission component to drive the material to move along the pipeline. When conveyed horizontally, the material particles are pushed by the chain in the direction of movement. When the internal friction between the material layers is greater than the external friction between the material and the pipe wall, the material will move forward with the chain piece, forming a stable material flow; when transported vertically, the material particles in the pipe are pushed upward by the chain piece, because the lower part The feeding prevents the upper material from sliding down and generates lateral pressure, thereby enhancing the internal friction of the material. When the internal friction between the materials is greater than the external friction between the material and the inner wall of the tube and the material's own weight, the material will be transported upwards with the chain. Form a continuous flow. Powder materials can move linearly or change direction along closed pipes in three-dimensional space; the horizontal conveying distance can reach 60 meters, and the vertical conveying distance can reach 30 meters.

In the process of conveying materials, the pipe chain conveyor has the characteristics of large conveying capacity, long service life, low maintenance cost, good sealing, safety and low energy consumption of the buried scraper conveyor. It also has the vertical conveying capabilities of the bucket elevator. capabilities, while the layout is more flexible (horizontal-vertical/inclined-horizontal) and the sealing performance is higher. There is no return material, no damage to the material, and no dust in the vertical conveying of materials. When conveying water-containing materials, easily adsorbed materials, and materials with very light specific gravity, an electric cleaner can be installed in the chassis.

二. Performance characteristics of pipe chain conveyor:

 1. It has a compact structure and takes up little space. It can change the conveying direction in three dimensions and is not affected by terrain, angle and height; the conveying process is carried out in a closed pipeline, and there is no flying dust; 

2. The conveying process is balanced, there is basically no internal movement between materials, and there is less damage, ensuring material quality, and is suitable for abrasive materials; 

3. There will be no system blockage and it is suitable for transporting various forms of materials; 

4. The transportation of mixed materials will not cause material stratification; 

5. Large conveying capacity and low energy consumption, greatly reducing equipment operating costs; 

6. All moving parts operate in a closed space, which is safe and reliable; 

7. Long-distance transportation can be achieved; 

8. Multiple inlets and outlets can be deployed at will to meet process requirements; 

9. It is easy to realize centralized control and improve the degree of automation.
