Abstract

The invention particularly relates to a safety protection system with function of preventing belt conveyor from hurting people for a coal preparation plant. The safety protection system solves the problem that an existing protection device of a belt conveyor cannot effectively protect people from being hurt by the belt conveyor. An alternating current power supply is connected with a power transformer which is connected with a central processing unit and a power tube respectively, the power tube is connected with a direct current port which is connected with a headpiece, a tail, a tail detector and an audible and visual alarm respectively, the headpiece, the tail and the tail detector are all connected with the central processing unit, a keyboard is connected with the central processing unit connected with the audible and visual alarm and a voltage comparator, the voltage comparator is connected with a PLC (programmable logic controller) port of a concentrated control center, and an emergency button is connected with the central processing unit. The safety protection system with function of preventing belt conveyor from hurting people for the coal preparation plant is reasonable and reliable in structure, can realize spot alarming and shutdown protection, and degree of automation of monitoring protection of the belt conveyor is improved.

Description

technical field [0001] The invention relates to a safety protection system for coal mines, in particular to a safety protection system for preventing a belt conveyor from injuring people in a coal preparation plant. Background technique [0002] In many coal preparation plants in my country, most of them use belt conveyors for coal transportation. During production, belt conveyors may have various accidents such as deviation, slipping, tearing, and injuries caused by rotating parts. With the improvement of mine production capacity and coal preparation plant processing capacity, or based on the impact of many pressures on production tasks, it will bring certain difficulties to safety production management. In order to ensure the safe operation of the coal preparation plant, the belt conveyors are equipped with safety protection devices such as longitudinal tearing, anti-deviation, temperature, slipping, and emergency stop along the line. However, during the long-term operati...
