In belt conveyors, the conveyor belt is an important component responsible for carrying and transporting the sinter.
In the conveying process of the sinter, because the sinter cooled by the annular cooler is irregular in granularity and uneven in size, the sinter transported to the belt conveyor is often mixed with insufficiently cooled height Wen Gongkuang, so that the conventional conveyor belt is easy to burn, and even deeper burning wounds are caused; in the transferring process, the problems of falling off of the grate bars of the sintering machine and the like are unavoidable, so that sharp foreign matters fall onto the conveying belt to scratch or even tear the conveying belt.
In the prior art, the tear resistance of the conveyer belt is improved by embedding a spiral penetrating steel wire mesh in the center of the conveyer belt, wherein the spiral penetrating steel wire mesh is an integrated steel wire mesh formed by alternately weaving steel wire ropes. Although the tearing resistance of the conveyer belt can be improved to a certain extent by using the conveyer belt, sharp foreign matters still cannot be prevented from penetrating through meshes of the spiral penetrating steel wire mesh, and then the whole conveyer belt is penetrated; in addition, once the integrally formed spiral penetrating steel wire mesh is locally broken, a chain reaction can be initiated, so that the whole conveyer belt is rapidly deteriorated until scrapped; meanwhile, two ends of the conveying belt need to be connected together for use, the conveying belt which is integrally formed and spirally inserted with the steel wire mesh cannot be connected by a method of cutting off the steel wire rope due to the reasons, and the conventional cementing process can cause low longitudinal strength and easy tearing of a joint due to the fact that the contact surface is too small, so that the conveying belt which is inlaid with the spiral and inserted with the steel wire mesh needs to be produced by special modes such as additional reinforcement, and the process is complex.
