Large capacity transportation capability: With excellent transportation capacity, it can fully meet the transportation needs of large capacity materials and improve production efficiency.
Reliable operation and easy automation: Stable and reliable operation, easy to achieve automation and centralized control. At the same time, it has low power consumption and minimal wear and breakage of materials, ensuring the quality and efficiency of material transportation.
The design of long-distance belt conveyors is a complex and meticulous comprehensive project that involves multiple key aspects to ensure their reliability, efficiency, and safety. The following are the core points of the design:
Firstly, the overall layout is crucial. When designing, it is necessary to carefully select routes that are closer and have less terrain fluctuations, taking into account the geographical locations of the feeding and discharging points of the long belt, in order to reduce construction difficulty and operating costs. At the same time, obstacles such as high-voltage lines, oil pipelines, densely populated residential areas, highways, railways, etc. should be avoided as much as possible in the layout area. If it is not possible to completely avoid it, consider designing the long belt in sections to achieve the optimal layout.
Secondly, the arrangement of the driving device is also crucial. Long distance belt conveyors typically use dual or multi drive systems to improve conveying efficiency and stability. The driving device can be flexibly arranged under the belt conveyor, or near the head or tail of the belt conveyor, for easy centralized power supply and daily maintenance.
In addition, the arrangement of rotation and flipping devices is equally important. The rotating device is used to adjust the direction of the conveyor belt, ensuring its normal operation and avoiding contact with the lower roller. The flipping device is used to change the conveying direction of the conveyor belt when necessary. The arrangement of these devices should be scientifically reasonable to ensure the smooth operation of the conveyor belt and reduce wear.
Meanwhile, the arrangement of the tensioning device cannot be ignored. The tensioning device is used to maintain the appropriate tension of the conveyor belt to ensure its stable operation. Common tensioning methods include heavy hammer, spiral, hydraulic, etc. When selecting, it is necessary to consider factors such as the length of the conveyor belt and tension requirements comprehensively.
In the design phase, dynamic analysis and precise calculation are also essential steps. Dynamic analysis software shall be used for accurate analysis and calculation of various working conditions, including cross sectional area check of materials, calculation of conveying capacity, calculation of tension at each point of conveyor belt, etc., to ensure the reliability and progressiveness of design.
Of course, considering safety performance is also an important aspect of design. The safety performance of the conveyor belt should be fully considered in the design, such as the installation of backstops, anti-skid devices, emergency stop devices, etc., to ensure the safety of the conveying process. At the same time, the strength of the conveyor belt should be checked to ensure that it can withstand various loads during operation.
Finally, for particularly long conveying distances, other special designs are also effective means to improve the performance and reliability of the conveyor. For example, advanced technologies such as soft start technology and longitudinal tear protection devices for conveyor belts can significantly improve the performance and reliability of the conveyor.
