Integrated monitoring device for conveying chain of coal sorting machine

Abstract

The invention provides an integrated monitoring device for the conveying chain of a coal sorting machine, and belongs to a conveying chain monitoring device. The upper monitor computer of the monitoring device monitors the performance of the main processing unit, the main processing unit receives and handles signals sent by the detecting unit, and controls a shutdown circuit and an alarm circuit; the speed detection unit detects the running speed and the direction of the conveying chain, the fault detection unit detects the faults of the two conveying chains, such as chain scission, chain falling, chain skipping, scraper plate dislocation and the like; the alarm circuit and the shutdown circuit conduct sound-light alarm and stop dragging motor order sent by the main controlling unit; the main controlling unit conducts self-locking after fault signal processing, and the reset of the main controlling unit is conducted by the reset circuit. According to the device provided by the invention, the running parameter of the conveying chain is detected in real time, and the conveying chain fault can be detected timely to stop dragging motor, the damage to the scraper plate and the fluidizer caused by continuous running of the motor after chain scission, chain falling is avoided effectively, and the staff allocation of the system operation and the workload maintenance are decreased.

Description

technical field [0001] The invention relates to a monitoring device for a conveying chain, in particular to a comprehensive monitoring device for a conveying chain of a coal sorting machine. Background technique [0002] Dense medium separator is a kind of coal separation equipment often used in the coal industry. Magnetite powder and coal powder are used as weighting materials, which are fluidized under the action of water or air. During the separation process, they are layered according to density The final light and heavy products are respectively discharged by the discharge mechanism. The sunken objects are scraped out by the scraper conveyor. Due to the long continuous operation time of the conveyor, the heavy load, and the harsh environment inside the machine, it is easy to cause problems such as wear, deformation, and fracture of the conveyor mechanism. If the failure of the conveyor chain can be found in time and the car can be stopped in time, the loss can be minim...
