Problems solved by technology
Excessive pre-tightening force at the initial stage will cause certain damage to the belt and reduce the service life of the belt
After a period of time, with the wear of the scraper, the pre-tightening force of the spring will decrease significantly, resulting in poor cleaning effect, and it must be manually imprisoned again, which will increase labor costs

The invention discloses a secondary material scraping device for a granulated blast-furnace slag belt. The device comprises a polyurethane knife edge scraping plate, material scraping device box bodies, balancing weight levers, balancing weight blocks and a transmission rod; and downward gravity of the balancing weight blocks is applied, the distance between the balancing weight blocks and gears can be adjusted by arranging the balancing weight blocks on the balancing weight levers, the transmission rod taking the gears as a shaft is driven to rotate, the gears rotate anticlockwise to drive arack of a connecting rod to be vertically upward, and therefore the polyurethane knife edge scraping plate on the connecting rod moves upwards so as to be tightly attached to the return belt to scrapoff accumulated materials.
Description
Technical field [0001] The invention relates to the field of scraping devices, in particular to a secondary scraping device for blast furnace water slag belts. Background technique [0002] Since the water content of blast furnace slag is 7%-9%, when the slag enters the vertical mill, it enters the vertical mill through the belt conveyor for grinding, and the water slag easily adheres to the surface of the return belt. The accumulation of materials in the frame of the belt head drum and the web of the belt conveyor is caused by the return of materials. The accumulation not only pollutes the working environment, but also affects the normal operation of transportation if it is not cleaned in time. [0003] Due to the spring structure of the current secondary cleaner, the pre-tightening force of the spring changes correspondingly as the scraper wears when cleaning the belt return. Too much pre-tightening force in the initial stage will cause certain damage to the belt and reduce the ...
