Coal ash roller screen

Abstract

The invention discloses a coal ash roller screen. The coal ash roller screen comprises a base, a roller screen body, a rotary drive motor, a funnel, a belt conveyor and a feeding slot, and further comprises a swing drive frame and a hinged supporting frame; the swing drive frame and the hinged supporting frame are separately arranged at the two ends of the base; the roller screen body comprises a rotary shaft and a screen barrel fixedly arranged on the outer periphery of the rotary shaft; one end of the rotary shaft is connected with the swing drive frame, and the other end of the rotary shaft is connected with the hinged supporting frame; the rotary drive motor is connected with the other end of the rotary shaft; the funnel is fixedly arranged on the base and is positioned below the screen barrel; the belt conveyor is fixedly arranged on the base and is positioned below the funnel; and the feeding slot can be detachably formed in the base and is positioned above the swing drive frame. The coal ash roller screen is reasonable in structural design; the swing drive frame and the hinged supporting frame can be connected with the roller screen body, so that the roller screen body swings up and down; and in a coal ash screening process, a better screening effect can be obtained, so that screening efficiency can be promoted to be improved.

Description

technical field [0001] The invention relates to the technical field of fly ash processing, in particular to a fly ash rolling sieve. Background technique [0002] During the processing of fly ash, fly ash needs to be screened; in the actual processing process, drum screens are used for screening, and the existing drum screens are structurally designed: the inclination angle of the screen drum is fixed, and the length of the screen drum is fixed The principle of screening is that the rotating drive motor drives the rotating shaft to rotate, and the rotating shaft drives the screen cylinder to rotate, and the fly ash slides down along the screen cylinder, and the fly ash that meets the requirements falls through the sieve holes on the screen cylinder, and the powder that does not meet the requirements The ash is discharged from the lower end of the sieve cylinder; during the production and processing process, the supply of fly ash increases, so that the fly ash accumulated in ...

Problems solved by technology

[0002] During the processing of fly ash, fly ash needs to be screened; in the actual processing process, drum screens will be used for screening. The existing drum screens are structurally designed: the angle of inclination of the screen drum is fixed, and the length of the screen drum is fixed. The principle of screening is that the rotating drive motor drives the rotating shaft to rotate, and the rotating shaft drives the screen drum to rotate, and the fly ash slides down along the screen drum, and the fly ash that meets the requirements falls through the sieve holes on the screen drum, and the unqualified powder coal The ash is discharged from the lower end of the sieve cylinder; during the production and processing process, the supply of fly ash increases, so that the fly ash accumulated in the sieve cylinder cannot be effectively screened, and the screening effect is not good. If the amount of fly ash is reduced supply will affect production efficiency
