Product description
DG series tubular belt conveyor
1. Introduction
1.1. Purpose
DG tubular belt conveyor series products are widely used in metallurgy, electric power, port, coal, mining, chemical industry, grain processing and other industries. It is a new type of continuous conveyor developed on the basis of ordinary belt conveyor, It is especially suitable for conveying bulk materials with long conveying distance, horizontal, vertical and spatial curved curve operation, large inclined angle and small floor area. This series of products are widely used to transport various bulk materials with a density of 0.5 ~ 2.5t/m 'under various complex terrain conditions. The operating temperature range of the common tubular tape is - 20 ~ + 40C, and the temperature of the transported materials is not more than 60 ° C.
If the working environment or the temperature of conveying materials exceeds this range, special tape shall be used.

1.3. Structural characteristics
1.3.1. Product classification. According to the type of belt equipped, the belt conveyor can be divided into two categories: fabric core belt conveyor and steel cord belt conveyor.
1.3.2. Characteristics of pipe belt machine.
1.3.2.1. The materials along the line are completely closed during transportation, which can not only prevent materials from spilling and polluting the environment, but also prevent the environment (dust, rain, etc.) from polluting the transported materials.
1.3.2.2. The pipe belt conveyor can be used for horizontal, vertical and spatial bending curve operation.
1.3.2.3. Due to the increased friction force of the belt on the material after the formation of the tube, it can realize the lifting of a large inclined angle (generally up to 1.5 times of the lifting angle of the ordinary belt conveyor).
1.3.2.4. After adding relevant auxiliary facilities, the return side can also seal the conveying materials.
1.3.2.5. Because the belt forms a tube, the width of the tube belt truss is only about half of the cross section of the ordinary belt conveyor under the premise of conveying the same amount of materials, and the floor area is small.
1.3.2.6. As the idler is installed on the window frame in the truss, the truss has a certain stiffness, so it is enough to install a walkway on both sides of the pipe belt conveyor truss, and there is no need to build another trestle.
1.3.3. Structure of main parts of pipe belt conveyor.
1.3.3.1. The shape and structure of belt conveyor belt of pipe belt conveyor and ordinary belt conveyor are identical, but compared with ordinary belt conveyor belt, the core structure of pipe belt conveyor belt is different.
1.3.3.2. Fabric core tape or wire rope core tape can be selected according to the length of pipe belt machine. Generally, fabric core belt is used for tubular belt conveyor with machine length less than 1000m, and steel cord belt is generally used for tubular belt conveyor with machine length greater than 1000m.
1.3.3.3. The structure form of the supporting roller used by the pipe belt conveyor is exactly the same as that of the ordinary belt conveyor. As the supporting roller used for the pipe belt conveyor, it is required to have small running resistance and better waterproof performance. For the ordinary belt conveyor, the groove angle of the groove roller is generally 35 ° while the side angle of the roller of the pipe belt conveyor is 60 ° and 90 ° respectively.
1.3.3.4. The configuration of driving device, the structure of drum, the setting of tension device, head and tail frame, funnel, shield, cleaning and other parts of pipe belt conveyor are identical with those of ordinary belt conveyor.
1.3.3.5. The steel structure of pipe belt conveyor is composed of truss, walkway, railing, pillar, etc.
1.4. Working principle
The tube belt conveyor is a kind of tube formed by the belt in the hexagon roller group. The structure of the head, tail and tension of the belt conveyor is the same as that of the ordinary belt conveyor. It is necessary to consider a certain length of transition section area from ordinary groove to round tube (or vice versa). The material is wrapped in a closed round pipe-shaped belt. During the conveying process, the conveyor can realize multi-directional turning due to the tube formed by the upper and lower belts. The maximum horizontal turning angle of the fabric core tube belt conveyor can reach 90 ° and the maximum horizontal turning angle of the steel cord belt conveyor can reach 45 °.

4. Selection method
The tubular belt conveyor can be arranged in many ways. The basic parameters of the belt conveyor, such as bandwidth, belt speed and power, can be determined according to the conditions such as the particle size, density, transportation volume, transportation distance, inclination angle and direction of the material. For the specific selection and process layout of the belt conveyor, please contact the manufacturer and design according to the specific conditions and environment.
