Abstract

The invention relates to the technical field of coal transportation, in particular to a coal feeding prevention device for a roller bearing of a coal conveying belt. The device comprises a wear-resisting partition plate rotationally connected to a transmission shaft and capable of covering one end of the roller bearing and a sleeve capable of being fixedly connected to the shaft, wherein a plurality of brush plates are evenly arranged at the end, close to the wear-resisting partition plate, of the sleeve in the circumferential direction; the brush plates are made of conductive materials; hairbrushes are arranged on the faces, close to the wear-resisting partition plate, of the brush plates; a plurality of cavities are formed in the brush plates; friction gaskets are fixedly connected to the inner walls of the cavities; balls capable of rotating in the cavities are arranged in the cavities; and electrostatic cloth capable of generating static electricity through friction with the friction gaskets is arranged on the surfaces of the balls. According to the device, the problem that traditional coal conveying process, pulverized coal enters the roller bearing, and the service life of the roller bearing is affected is solved.

Description

technical field [0001] The application relates to the technical field of coal material transportation, and specifically discloses a coal conveying belt roller bearing anti-coal ingress device. Background technique [0002] The coal conveying belt is an important auxiliary equipment in a thermal power plant, and its operation stability directly affects the coal burning safety of the main engine. The roller bearings are installed on the drive shaft of the coal conveying belt. Due to the dust pollution in the coal conveying system, especially the coal sticking to the belt, it is easy to cause coal accumulation around the roller, which will cause finer coal powder to rotate along the shaft and enter the roller. Bearing, roller bearing refueling, oil change cycle is shortened, and the amount of maintenance is increased. If the maintenance is not in place, the bearing will be damaged, and even the roller journal will be worn. In daily maintenance, when adding lubricating oil to ...
