Description

TECHNICAL FIELD

[0001] The present application belongs to the field of conveying facilities, and relates to a tubular belt conveyor. BACKGROUND

[0002] As a common material conveying equipment, the tubular belt conveyor is widely used in cement, coal, metallurgy, chemical industry and other industries. These devices mainly serve the occasions of complex conveying route, existence of obstacles, requirement of no dust pollution, and long-distance and high-height conveying. The tubular belt conveyor not only can effectively seal the material and prevent environmental pollution, but also is particularly suitable for long-distance and high-height material conveying requirements, so it has been widely applied in many industries.

[0003] With the continuous promotion of energy conservation and environmental protection and safety production concept, the requirements for material conveying equipment are also getting higher and higher. As an important material conveying tool, the application range and importance of the tubular belt conveyor are expected to further expand in the future.

[0004] In the traditional design, the tubular belt conveyor usually adopts a middle part extrusion forming method of carrier roller. This method maintains the tubular shape of the belt through the support of multiple carrier rollers throughout the conveying process, realizing the conveying of the material. Its advantages lie in simple structure and convenient operation. However, this method also has some problems. For example, in the conveying process, the belt will deform and be extruded, resulting in a large friction between the carrier roller and the belt. With the increase of conveying distance, the number of carrier rollers required will also increase, thereby intensifying the friction, bringing more energy consumption and increasing the construction and maintenance cost. SUMMARY

[0005] Therefore, the purpose of the present application is to provide a tubular belt conveyor. The device adopts an innovative belt tube running mechanism to replace the traditional carrier roller middle part extrusion forming method. This new running mechanism does not generate tube resistance in the middle running section of the conveyor, effectively reducing the running resistance, reducing energy consumption, and saving construction and operation cost. In addition, this design optimizes the forming mode of the traditional tubular belt conveyor, ensures the full-tube of the belt throughout the conveying process, realizes the full-closed and green conveying of the material, and helps to promote the development of the conveying industry in a safer, greener and lower-carbon direction.

[0047] The belt pipe running mechanism 5 is composed of wheel set 12, pipe-holding mechanism 13 and supporting mechanism 14. The wheel set 12 and the supporting mechanism 14 are connected as a whole by welding, bolting or the like and then installed on the track 7, the pipe-holding mechanism 13 is connected to the supporting mechanism 14 by welding, bolting or the like, and the three are connected to form the belt pipe running mechanism 5, as shown in Figure 4 and Figure 5The tape forming mechanism 5 is installed at a position which can be adjusted according to the specific position of the track 7, which is convenient for adjusting the running amount and the pipe diameter, and also convenient for on-site installation. The tape forming mechanism 5 is arranged at a certain distance, which can realize the full pipe forming of the tape 8 in the carrying section and the return section.
