Coke conveyor belt interface method

Generally, there are several common methods for belt joints, such as mechanical joints, cold adhesive joints, and heat-vulcanized joints. 1. Mechanical connectors: One type is the belt buckle connector. This type of connector is convenient and cost-effective. If the belt gets damaged during use and a new belt needs to be installed, it is easy to replace the belt buckle connector. However, its efficiency is low and it tends to get damaged, which can affect the service life of the conveyor belt. 2. Cold adhesive joints: These are joints created using cold adhesives, a method in which the ends of the conveyor belt are connected together with adhesive as the bonding material. The quality of such cold adhesive joints depends crucially on the type of adhesive used and whether a seamless connection has been achieved. Due to its advantages of high joint strength, noise-free and vibration-free operation, simple handling, and short joining time, this method is widely used. However, in practice, it is not very stable because the process conditions are difficult to control, and the quality of the adhesive has a significant impact on the joints. Additionally, cold-adhesive conveyor belts are not suitable for materials that are sensitive to humidity or temperature requirements. 3. Thermosulfurized joints: The belt interfaces of thermosulfurized joints are completely sealed, making them resistant to water penetration. The process for vulcanizing belt joints generally involves placing the lower frame of the vulcanizer on the belt frame, aligning its ends, and then placing a hydraulic plate, a small insulating plate, and a lower insulating plate in sequence. Platforms measuring 1–2 meters in length are installed on each side of the two vulcanizers and secured in place; the upper surface of these platforms should be at the same level as, or slightly lower than, the upper surface of the lower heating plates. Meanwhile, it is important that this setup does not affect the tension applied by the tie rods. The two belt joints are then placed on these platforms to begin the vulcanization process. This method is currently the most ideal joining technique; it ensures high joining efficiency, is highly stable, provides a long service life for the joints, and is easy to master. However, the heat-vulcanization joining process is complex and requires skilled personnel, whereas the cold-adhesion process is simpler and allows workers to start working after short training.
