Due to the increasingly urgent requirements for environmental protection all over the world, since the birth of circular tube Belt Conveyors in 1972, all walks of life have been put into use. The round tube Belt Conveyor, as the name implies, is the conveyor belt in the form of a round tube during the conveying process, and conveys the material on the rack. The material enters the feeding section from the feeding hopper at the end, and the conveyor belt changes from a flat shape to a U shape, and then gradually changes to a round tube shape through the transition section, wrapping the material and running in a closed manner. When conveying to the head for filtration, the tubular conveyor belt gradually expands from a U shape to a flat shape to unload the material. The carrying and return process can be formed into a circular tube or run in parallel.
1. Development history of round tube belt conveyor
In 1972, in order to solve the problem of environmental protection, Japan developed a circular tube belt conveyor, and in 1975, it applied for a patent for a circular tube belt conveyor and began to put it into production. After 1978, there were Bateman Company of South Africa, Koch Company of Germany, Young Poony Company of South Korea, and Sistemas Company of South America successively producing round pipe belt conveyors. Since China introduced the technology of circular tube belt conveyor, especially after the reform and opening up, my country's circular tube belt conveyor has grown from nothing, and the development speed is fast, we can see the strong demand in our country, which shows that the circular tube belt conveyor Machines are a product of an era.
Second, the advantages of the round tube belt conveyor
1. Green and environmental protection
In recent years, green design has become a major theme in the design industry. The so-called green design refers to a modern manufacturing model that comprehensively considers environmental impact and resource efficiency under the premise of ensuring the function, quality and cost of the product. Or environmental pollution is minimized, it meets the requirements of environmental protection, is harmless or has little harm to the ecological environment, saves resources and energy, maximizes resource utilization, and minimizes energy consumption. In 2003, my country promulgated the Cleaner Production Promotion Law. Cleaner production refers to continuously taking measures such as improving design, using clean energy and raw materials, adopting advanced technology and equipment, improving management and comprehensive utilization to reduce pollution from the source. Improve resource utilization, reduce or avoid the generation and discharge of pollutants in the process of production, service and product use, so as to reduce or eliminate harm to human health and the environment. The circular tube belt conveyor shoulders such a historical mission. In the process of material conveying, the material is wrapped by the round pipe conveyor belt, which avoids the waste of materials and air pollution caused by various reasons, and truly plays a role in green environmental protection.
2. Economic benefits
According to the statistics of China Logistics Information Center, in 2002, the cost of material handling in my country accounted for 21.5% of the annual GDP, while the cost of material transportation in Japan accounted for 10.7% of GDP, and the cost of material handling in Germany and the United States accounted for 10% of GDP~ 20%. It can be seen from the data that material transportation costs account for 1/5 of the GDP, and the proportion of material transportation expenses in my country is relatively high. The material transportation methods mainly include railway and road belt transportation. Among these transportation methods, belt transportation has the lowest cost.
3. Structural features
Compared with other material conveying equipment, the belt conveyor first conveys a wide range of materials. All bulk materials, powder materials, block materials, viscous and non-viscous materials, and even ice cubes and water can be transported; During transportation, it can prevent external debris from mixing into the conveyed material, and also prevent the material from being damaged by rain or sunlight, and can realize the complete closed transportation of the carrying section and the return section, which can avoid material leakage and sprinkling in principle. The line has strong adaptability and can realize flexible layout design. It can realize small-radius three-dimensional space turning and large-angle inclination. It can climb up and cross the river, and can build three-dimensional turning and vertical climbing round tube belt conveyors along the surface, avoiding the establishment of intermediate transfer stations and the development of corresponding auxiliary round tube belt conveyors and the investment in key technical equipment and equipment. Maintenance costs; Third, two-way material conveying can be realized. Since the circular tube belt conveyor adopts closed tube conveying in the bearing section and the return section, if a feeding port is added in the return section, the return section can still transport materials, and the middle Loading and unloading can be done by opening and closing the conveyor belt at any point; fourth, reliable operation, low maintenance costs, and even replacement of parts and repair of conveyor belts without stopping, which brings great benefits to safe production, especially The application of repairing conveyor belts with nanomaterials is simpler to operate.
3. Development Prospect of Tube Belt Conveyor
The future is a prosperous period for the development of circular tube belt conveyors. The emergence of the invention patent of the circular tube belt conveyor in China solves the problems of vertical conveying and small radius turning, breaks through the two-dimensional transportation, and promotes the development of the circular tube belt conveyor. In the face of the increasingly severe global environmental protection situation, with the protection of ecology, the prevention of dust pollution, and the economical advantages of circular pipe belt conveyors in transportation, circular pipe belt conveyors will surely appear in his prosperous era.
