Background

The pipe chain conveyer is a continuous conveyer for conveying powder, small granular and small block-like bulk materials, and can be used for horizontal, inclined and vertical combined conveying. Is generally used in fine chemical industry, pesticide ore, building material, food industry and the like. In the closed pipeline, the chain sheet is used as a transmission component to drive the material to move along the pipeline. When horizontally conveyed, the material particles are pushed by the chain sheet in the moving direction. When the internal friction force between the material layers is larger than the external friction force between the material and the pipe wall, the material moves forwards along with the chain sheet to form a stable material flow; when the material is conveyed vertically, the material grains inside the pipe are pushed upwards by the chain sheet, and the feeding material in the lower part prevents the material in the upper part from sliding downwards to produce lateral pressure, so that the inner friction force of the material is increased. The existing product in the pipe chain conveyor market has the problem of chain falling, and the problem cannot be effectively solved, and the structure is not reasonable.
