The conveyor that is pulled by a scraper chain and transports bulk materials in the tank is called a scraper vibration conveyor. Scraper conveyor is an important transportation tool used to transport materials in coal mines, chemical mines, metal mines and power plants. It is composed of the middle groove, chain, scraper and traction system.
The function of the scraper conveyor is not only to transport coal and materials, but also the running track of the shearer, so it has become an indispensable main equipment in the modern coal mining process. The scraper conveyor can be used for horizontal transportation or inclined transportation. The inclination angle of the coal seam shall not exceed 25° when transporting along a slope, and the inclination angle shall not exceed 20° when transporting downward. When the inclination angle of the coal seam is large, anti-skid devices should be installed.
In the application of scraper vibration conveyor in various industries, attention should be paid to maintenance. The specific points are introduced as follows:
- Before starting the scraper conveyor, check whether the power supply of the reducer, the traction fluid and the lubricating oil level are normal.
- The working environment temperature of the speed reducer of the scraper conveyor should not exceed 40℃, and the temperature rise should be lower than 40℃.
- The scraper conveyor should be inspected, repaired and maintained regularly.
- All lubrication parts of the scraper conveyor should be lubricated according to regulations.
- When the scraper conveyor is overhauled, the gate must be closed before the overhaul can be carried out.
- The gate must be closed before the scraper conveyor is stopped, so that it can start without load when it is turned on again, which can protect the motor, reducer and belt and prolong the service life of the equipment.
