A belt conveyor is a device used to transport materials from one place to another in industrial production. It consists of a continuous belt-shaped material conveying system with strength and flexibility, usually consisting of one or more parallel belt-shaped material conveying belts. Belt conveyors are widely used in mining, ports, metallurgy, coal mines, chemical industry, electric power, food and other industries. The main components include: conveyor belt, transmission device, roller, support device, tensioning device, roller, driving device, structural support, etc.
The working principle of the belt conveyor is to use the driving equipment to drive the conveyor belt to run. The materials are placed on the conveyor belt and the materials are transported from the starting point to the target point through the roller. At the same time, the speed and direction of the conveyor belt can be adjusted as needed. Conveyor belts can support and transport materials through flat floors or support structures.
In order to ensure a safe and efficient production and transportation environment, belt conveyors will be equipped with protection switches. Protection switches for conveyor belts generally include the following:
1. Operation monitoring switch: used to monitor the operating status of the belt. Once an abnormal stop occurs, such as breakage, deviation, etc., the switch can be triggered to stop the belt operation to prevent further damage. For example, a rope pull switch:
2. Breakage monitoring switch: used to monitor whether the belt breaks. Once broken, the switch will trigger to stop the belt operation. For example tear detector:
3. Deviation monitoring switch: Used to monitor whether the belt is deviating. Once the belt is deviating, the switch will trigger to stop the belt. For example, deviation switch:
4. Abnormal speed monitoring switch: used to monitor whether the running speed of the belt is abnormal, such as overspeed or low speed. Once the set value is exceeded, the switch will trigger to stop the belt operation. For example, speed detection sensor:
5. Equipment blockage monitoring switch: used to monitor whether the conveying equipment is blocked. Once blocked, the switch will trigger to stop the belt operation to prevent equipment or material accumulation from causing hidden dangers. For example, a chute blockage detector:
The use of these protection switches can ensure that the conveyor belt can be stopped in time during operation, reduce the risk of accidents, and protect personal safety and the normal operation of the equipment.
