Device for removing freeze-adhered coal on surface of belt

Abstract

The invention discloses a device for removing freeze-adhered coal on the surface of a belt. The device comprises a stripping mechanism and a sweeping mechanism, wherein the sweeping mechanism is located behind the stripping mechanism; the stripping mechanism is composed of spiral rollers (2), a spiral roller support (1), a spiral roller bearing (5), supporting rollers (3), a supporting roller support (12), a supporting roller bearing (4), a compression adjusting mechanism support (6), a screw rod (7), a nut sliding block (8), a limiting shaft sleeve (10) and a spiral roller support connectingbearing (9); and the sweeping mechanism is composed of a scraping plate (17), a scraping plate support (14), a support connecting rod mechanism (15), an electro-hydraulic push rod (16) and a scrapingplate supporting carrier roller (18). According to the device, when the belt (11) runs, the spiral rollers (2) and the supporting rollers (3) are driven to rotate, so that the freeze-adhered coal powder attached to the surface of the belt are effectively stripped off, the freeze-adhered coal powder are transferred to the ground on the two sides of the belt through the sweeping mechanism, and therefore the phenomenon that the belt is wrapped and even damaged due to the fact that the freeze-adhered coal powder are attached to a rotating guide roller is prevented.

Description

technical field [0001] The invention relates to a device for cleaning frozen coal on the surface of a belt. Background technique [0002] In winter in the north, the outdoor temperature is usually minus 10-30°C. When the warm coal unloaded by the dumper enters the dry coal shed, it must pass through an outdoor coal conveyor belt. During transportation, some coal powder will always remain and freeze. On the working surface of the belt, this part of the frozen coal powder entering the belt conveyor roller, idler roller or belt deflection adjustment bracket slewing bearing will accelerate the damage of the equipment, especially the accumulation of the guide roller will cause the belt to bulge, and the belt will be damaged in severe cases. Whether it is a scraper type or a threaded roller type, the belt cleaners commonly used at present are installed on the return path of the belt, between the rollers at both ends of the belt conveyor. The coal dust that comes down is difficult...

AI Technical Summary

Problems solved by technology

Whether it is a scraper type or a threaded roller type, the belt cleaners commonly used at present are installed on the return path of the belt, between the rollers at both ends of the belt conveyor. The disadvantage is that it cannot solve the problem of coal sticking in the front of the cleaning device, and clean The coal powder that comes down is difficult to clean up

In addition, the current conventional scraper belt cleaners all use a spring tension mechanism, the tension force cannot clean the frozen coal on the belt surface, and the scraper made of polymer material is easy to wear and has a short service life.
