Tubular conveyor, especially the tubular belt conveyor, is a new type of conveyor which is innovated on the basis of belt conveyor. It curls the conveyor belt of the bearing and return branch into a tube shape, which has the advantages of pipeline transportation and belt transportation. The following is a detailed description of the tubular conveyor:

1. Definition and Characteristics

Tubular belt conveyor is a kind of belt conveyor that curls the conveyor belt into a tubular shape. It combines the advantages of pipeline transportation and belt transportation. It has the advantages of large conveying inclination, small curvature radius, small cross-sectional area of the fuselage, and three-dimensional space. This conveyor is convenient for the layout, maintenance and management of the conveying line, but the block size of the material is limited by the width of the conveyor belt, and is not suitable for occasions where the conveying line is short and multiple materials are received or discharged (except for the guide roller roller type tubular belt conveyor).

2. working principle

The working principle of the tubular belt conveyor is to drive the conveyor belt through a driving device to form a tubular shape. The material enters the conveyor pipe through the feed port, and with the movement of the conveyor belt, the material is transported to the designated discharge port. In the conveying process, the friction between the material and the conveyor belt is the main source of power for material conveying. Because the tubular belt conveyor has high inclination adaptability, it can carry out material transportation under the condition of large slope.

3. type and structure

Tubular belt conveyors can be divided into many types according to their structure and characteristics, such as self-enclosed, round end discs and rectangular end discs. Among them, the rectangular end disc tubular belt conveyor is the most widely used and the most mature technology. The load and return branch of this conveyor has a total of 12 idlers, which are divided into two groups and installed on two planes of the rectangular end plate, forming two regular hexagonal sections respectively. In the receiving area, the conveyor belt is in a straight state at the roller, then gradually transitions to a U-shaped state, and finally becomes a tubular shape. In the unloading area, the process is just the opposite.

4. Application Areas

Tubular belt conveyor is widely used in coal, ore, grain, cement, pulp and concrete and other kinds of block and powder material transport. It can play an important role in many industries such as mines, ports, power plants, cement plants, etc. For example, in a mine, a tubular belt conveyor can transport ore from a mining site to a concentrator; in a port, it can be used for bulk cargo handling and transportation; in a power plant, it can be used for coal transportation, etc.

5. advantages and characteristics

Good environmental protection: Because the conveyor belt is curled into a tubular shape, the material will not be spilled during the conveying process, reducing environmental pollution.
Strong adaptability: the tubular belt conveyor can adapt to the larger conveying inclination, realize the steering of three-dimensional space, and can transport almost any kind of bulk materials.
Smooth operation: The conveyor belt runs more smoothly in the tubular state, reducing vibration and noise.
Convenient maintenance: The structure of the tubular belt conveyor is relatively simple, and it is more convenient to maintain.

6. Maintenance and Maintenance

In order to ensure the long-term normal operation of the tubular belt conveyor, regular maintenance and maintenance are required. This includes checking the wear of the conveyor belt, adjusting the tension of the conveyor belt, lubricating key components, and checking the working status of the electrical system. Through effective maintenance and maintenance, the service life of the conveyor can be extended and the production efficiency can be improved.

In summary, the tubular belt conveyor is an efficient, environmentally friendly and adaptable conveying equipment, which plays an important role in many industries. With the continuous progress of technology and the continuous expansion of application fields, the application prospect of tubular belt conveyor will be broader.
