Description

Technical Field

[0001] The utility model relates to a cleaning device, in particular to a device capable of cleaning water slag sticking materials on a belt conveyor, belonging to the technical field of belt conveyor water slag sticking material cleaning equipment. Background Art

[0002] Water slag refers to blast furnace slag. In a high-temperature molten state, it is rapidly cooled with water to become a granulated foam shape. Water slag is ground into micro powder and is the main material for making cement. Water slag is mostly conveyed by belts, and belt sticking is the main problem of water slag conveying and the main difficulty to overcome. At present, polyurethane scrapers and alloy scrapers are mostly used for cleaning in the market, but the effect is not good. Alloy scrapers are easy to damage the belt, and polyurethane scrapers have poor use effect. Over time, it will cause local wear of the scraper, resulting in the top surface of the scraper no longer being flush, affecting the scraping operation. If the belt sticking is not cleaned in time, it will cause the belt to deviate and there is a risk of belt damage. After the belt sticks, the water slag will fall under the belt frame, increasing the labor intensity of employees. Therefore, a sticking cleaning device is needed, which is required to clean the water slag sticking on the belt in time to ensure the normal operation of the belt conveyor. Utility Model Content
