The tubular chain conveyor is a continuous conveying device designed for transporting bulk materials such as powders, fine granules, and small lumps. It is capable of conveying materials in horizontal, inclined, and vertical configurations, or in combinations thereof. Operating within a sealed pipeline, the system utilizes chain links as the driving components to propel the material along the length of the pipe.
During horizontal conveying, the material particles are subjected to a thrust force from the chain links acting in the direction of motion. When the internal friction between the layers of material exceeds the external friction between the material and the pipe wall, the material moves forward in tandem with the chain links, forming a stable flow. During vertical conveying, the material particles within the pipe are subjected to an upward thrust from the chain links. Since the continuous feeding of material from below prevents the upper material from sliding back down, a lateral side pressure is generated, thereby enhancing the internal friction within the material. When this internal friction between the material particles exceeds the combined resistance of the external friction against the pipe wall and the material's own weight, the material is conveyed upward along with the chain links, forming a continuous flow.
The aforementioned conveying processes all take place within a sealed pipeline, thereby ensuring dust-free operation with no leakage.
