the lower belt after the vibrating component is subjected to slag removal treatment through a dust-binding belt;
s5, when the tension sensor or the speed sensor correspondingly detects that the tension or the speed is abnormal, the controller analyzes and judges that the belt is broken after receiving the tension or the speed signal, the controller controls the hydraulic cylinder and the upper roller to stop rotating, the hydraulic cylinder drives the grabbing roller to rapidly move downwards, the grabbing roller and the upper roller clamp and fix the lower belt, the belt conveyor stops moving, and the risk brought by the belt breakage is reduced.
Compared with the prior art, the conveyor belt tectorial membrane deslagging device has the advantages that as the dust-binding belt is in close contact with the lower belt, the dust-binding belt can adhere to and deslagge the lower belt by spraying the adhesive, spraying clear water, scraping and deslagging, smearing the adhesive and microwave drying on the dust-binding belt, the width of the dust-binding belt is larger than that of the lower belt, and the lower belt can keep adhering and deslagging with balanced stress, so that the problem that the deslagging effect of the lower belt is poor, and the water consumption is large and the water splashes are caused by continuous running of water spraying cleaning on the belt is avoided;
because the second ultrasonic sensor for detecting the amount of the adhesive cinder of the adhesive dust belt is arranged at the adhesive cleaning scraping part, when the adhesive dust belt is detected to be adhered, the movable assembly can be controlled to drive the scraping plate to be far away from the adhesive dust belt, the spraying assembly and the adhesive coating assembly do not act, the continuous execution of the adhesive dust belt cinder is ensured, and the corresponding colloid dosage is reduced; when the dust-sticking belt is detected to have more adhering cinder, the movable assembly can be controlled to drive the scraping plate to contact the dust-sticking belt, and the spraying assembly, the spraying assembly and the gluing assembly act to ensure the effective cinder-removing treatment of the dust-sticking belt;
