Description

Technical Field

[0001] The utility model relates to the technical field of pipe chain material conveying devices, in particular to a dust-proof pipe chain material conveying device. Background Art

[0002] The tube chain conveyor is a continuous conveying equipment for conveying bulk materials such as powder, small particles and small blocks. In a closed pipeline, the chain is used as a transmission component to drive the material to move along the pipeline. When conveying 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 moves forward with the chain to form a stable material flow; when conveying vertically, the material particles in the pipe are pushed upward by the chain. Because the lower feeding prevents the upper material from sliding down, lateral side pressure is generated, so the internal friction of the material is enhanced. When the internal friction between the materials is greater than the external friction between the materials and the inner wall of the pipe and the weight of the materials, the materials are conveyed upward with the chain to form a continuous material flow. It is a fully enclosed conveying method without dust leakage, and there is no need to set a dust collector at the outlet.

[0003] When the tube chain conveyor is in use, the scraper plate pushes the material to move and transport in the pipeline. When conveying powdery materials, the powder is likely to adhere to the surface of the scraper plate, causing waste of material. In order to reduce the adhesion of powder to the scraper plate, an anti-dust tube chain material conveying device is provided. Utility Model Content
