Belt conveyor is a common material transportation equipment, which is widely used in industries such as mining, metallurgy, and coal due to its simple structure, large transportation capacity, and long transmission distance. Below, I will provide a detailed description of the structure and working principle of the belt conveyor.
Structure of belt conveyor:
The belt conveyor mainly consists of drag device, support device, conveyor belt, tension device, cleaning device, and other parts.
- Drag device: Drag devices can be divided into two types: electric devices and non electric devices. Electric devices usually consist of electric motors, reducers, couplings, etc., which drive the conveyor belt through a transmission device. Non electric devices are usually driven by diesel engines or hydraulic stations.
- Support device: The support device is used to support the conveyor belt and its load, usually composed of a support frame and a support roller. The supporting rollers are arranged on both sides of the conveyor to support the conveyor belt and maintain its horizontal operation.
- Conveyor belt: The conveyor belt is the most important part of a belt conveyor, responsible for conveying materials. The conveyor belt is woven from rubber, canvas, or metal wire and has a certain tension and strength. The conveyor belt can be divided into two forms: direct laying and drum conveyor belt, which can be selected according to the needs of the site.
- Tension device: The tension device is used to adjust the tension of the conveyor belt and maintain the appropriate tension of the belt conveyor. Usually composed of tensioning drum, tensioning device, and lagging drum, etc. The tensioning roller adjusts the device to tension or release the conveyor belt to maintain a certain tension.
- Cleaning device: The cleaning device is used to remove materials adhering to the conveyor belt and maintain the cleanliness of the belt conveyor. Usually composed of scraper, drum cleaner, etc. The scraper is close to the conveyor belt, and the material is removed from the conveyor belt by the pressure of the scraper. The drum cleaner rolls the material off through the rotation of the drum.
