Discusses the development trend of belt conveyor technology (Including the dynamic analysis and monitoring technology of belt conveyor, controllable soft start technology and power equalization technology), the performance of the equipment and the performance of the belt conveyor, and the development of the belt conveyor at home and abroad. Reliability, life.
The development of foreign belt conveyor technology is very fast, especially in two aspects: one is the belt conveyor function diversification, the scope of application expansion, such as high angle belt conveyor, tubular belt conveyor, space Turn belt conveyor and other models. The other is the belt conveyor itself, the technology and equipment has been a huge development, especially long distance, large volume, high speed and other large belt conveyor has become Development of the main direction, the core technology is developed for the belt conveyor dynamic analysis and monitoring technology to improve the belt conveyor running performance and reliability. At present, the use of coal mine belt conveyor has reached the main technical indicators shown in Table 1, the key technologies and equipment have the following characteristics
1. large-scale equipment. Its main technical parameters and equipment are toward the large-scale development to meet the annual output of 300 to 500 million t high-yield and intensive production needs.
2.application of dynamic analysis technology and mechanical and electrical integration, computer monitoring and other high-tech, high-power soft start and automatic tension technology, the conveyor for dynamic monitoring and monitoring, greatly reducing the conveyor belt tension, equipment performance , High transport efficiency.
3. using multi-machine drive and the middle of the drive and its power balance, conveyor operation and other technologies, so that the length of the conveyor stand-alone operation has been limited in theory and to ensure that the transmission system equipment versatility, interchangeability and its unit Driven reliability.
4.New, high reliability key components of the technology. Such as including the CST, including a variety of advanced high-power drive and speed control device, high-life high-speed roller, self-cleaning roller device, efficient storage device, fast self-moving tail. Such as the FSW produced by the British FSW1200 / (2 ~ 3) × 400 (600) working surface belt conveyor belt on the use of liquid viscosity or frequency control device, transport capacity of 3000 t / h or more, its machine Tail and the new type of reloading machine (such as the United States Jiuyi company’s S500E) supporting, with the face of the move and automatically move from the fast, less manual work, high production efficiency.
With the rapid development of China’s national economy, China’s energy, electricity, metallurgy, building materials, terminals and other industries have also been a great opportunity for development, and conveyor belt products and the development of these industries are closely related, but also on the development of the national economy To a very critical role. In the international market environment, the Chinese rubber industry conveyor belt industry to face the new environment, how to maintain a good momentum of sustained development, more and more attention from the industry.
