Description

Technical Field

[0001] The present application relates to the field of conveying technology, and in particular to an anti-deviation conveyor belt and a conveyor. Background Art

[0002] The hot asphalt mixture microwave heating box is the core equipment of the microwave heating mixing station. Its normal, continuous and stable operation is the key to ensuring the normal production of the microwave heating mixing station. However, due to the high viscosity of the hot asphalt mixture, and the uneven heating in the microwave heating box and uneven material laying on the conveyor belt, the current steel belt conveyor belt has the problem of deviation during long-distance transportation. Taking the hot RAP conveyor as an example, if the microwave-heated RAP layer is heated unevenly, it will cause local overheating and elongation of the steel belt, which will cause unstable changes in the tension of the steel belt. If the RAP material cannot be evenly distributed on the conveyor steel belt during the blanking process, the uneven distribution of the steel belt tension will be further aggravated during the transportation process. In the process of long-distance transportation, this situation will be further aggravated, causing the steel belt to deviate, affecting production efficiency. At the same time, the viscosity of asphalt contained in hot asphalt mixture is very high, and the problem of adhesion to the conveyor belt cannot be ignored. When the existing steel belt increases the preload force by adding rollers during the return journey, the asphalt adhered to the surface of the steel belt may adhere to the rollers and gradually accumulate over time, eventually causing uneven force on the steel belt and aggravating the deviation phenomenon. These factors work together to not only seriously affect the normal service life of the equipment, but also greatly weaken its use function. Summary of the invention

[0021] The hot asphalt mixture microwave heating box is the core equipment of the microwave heating mixing station. Its normal, continuous and stable operation is the key to ensuring the normal production of the microwave heating mixing station. However, due to the high viscosity of the hot asphalt mixture, and the uneven heating in the microwave heating box and uneven material laying on the conveyor belt, the current steel belt conveyor belt has the problem of deviation during long-distance transportation.
