Description

Novel low-resistance circular tube belt conveyor

Technical Field

The utility model relates to a novel low resistance pipe belt conveyor.

Background

The belt conveyor is ideal efficient continuous transportation equipment, has the advantages of long conveying distance, large conveying capacity and the like, is reliable in operation, and is easy to realize automation and centralized control. With the demand of automatic mining work, the belt conveyor has obvious operation advantages, so the belt conveyor is widely applied to various industries such as ports, wharfs, cement metallurgy and the like. In recent years, the main development direction of belt conveyors is the large-scale development direction of long distance, high belt speed, large conveying capacity and high power.

However, since the conventional belt conveyor uses a certain number of idler sets to support the belt, the conveyor belt is in a groove shape with a certain forming angle. In the operation process of the belt conveyor, the conveying belt continuously passes through different carrier roller groups along the line. The inherent motion loss in transportation of the conveyor belt, such as the collapse resistance between the conveyor belt and the carrier rollers and the extrusion resistance of the material passing through the carrier roller group, exists every time the conveyor belt passes through the carrier roller group, so that the transportation distance of the traditional belt conveyor can not be infinitely prolonged under the same transportation conditions.

The wheel type round tubular belt conveyor is a novel wheel type round tubular belt conveyor which is a novel belt conveyor technology which is provided for overcoming the indentation resistance of a conveyor belt and the internal extrusion resistance of materials; the wheel type round tube-shaped belt conveyor changes a conveying support structure, and the conveying belt and the round tube moving trolley are relatively static in the operation process, so that the indentation resistance and the extrusion resistance of materials passing through a carrier roller are eliminated, and the two resistances account for about 60% of the resistance of the traditional belt conveyor.

In addition, the conveying belt and the circular tube moving trolley are relatively static, and the deviation of the conveying belt is not considered in the middle-range running process, so that the resistance is extremely small like a train running, the belt strength and the running power are greatly reduced, and the conveying distance is prolonged. The power is generally less than half of the idler support. The operation is stable, the service life is long, the replacement can be carried out at a driving point, and the maintenance is almost not carried out.
