In the mid-1970s, a new type of conveyor - air cushion belt conveyor - was adopted in industrial conveying systems abroad. Its novel structure, innovative principles, significant energy-saving effects, and extensive adaptability attracted the attention of the world. In the early 1980s, many developed countries in Europe and America widely adopted this type of air cushion belt conveyor in mines, ports, factories, and achieved significant economic benefits.
Innovative Technology of the Second Generation New Air Cushion Belt Conveyor
1. The innovation of design theory - replacing the limited fan-shaped airflow direction theory with scientific water ripple airflow direction theory, greatly improves the uniform stability of air cushion.
2. Innovation in design method - replacing the primary groove angle design method with the secondary groove angle design method, the air box structure is more scientific and reasonable, overcomes the phenomenon of tape edge scraping, improves operating efficiency by 20%, and saves air consumption by 15%.
3. The innovation of throttle hole arrangement - replacing the parallel arrangement method with the five point throttle hole arrangement method, not only optimizes the matching relationship between air volume and air pressure, but also improves the bearing capacity of the air cushion layer and expands the application range of air cushion belt conveyors.
4. The innovation of the air box structure - replacing the integral air box with a combination air box not only greatly reduces welding deformation and improves the sealing performance of the air box, but also for maintenance and overhaul, once the slot is damaged, there is no need to replace the entire throttle box. Only the slot needs to be replaced, greatly reducing maintenance costs.
5. Innovation of air source device - adding a separation and diversion device, which can not only reasonably distribute and guide air, but also greatly reduce the loss of airflow resistance along the way.
6. Innovation in Wind Source Matching - The first generation of air cushion belt conveyors usually use ordinary fans such as 9-19, 4-72, 9-26, 4-68, etc. These fans often cannot match the characteristics of air cushion belt conveyors, resulting in poor air cushion stability.
