Coal ash roller screen

Abstract

The invention discloses a fly ash rolling screen; it includes a base, a rolling screen body, a rotary drive motor, a funnel, a belt conveyor and a feeding trough, and also includes a swing driving frame and a hinged support frame, the swing drive frame and the hinged The supporting frames are respectively arranged at both ends of the base, and the rolling screen body includes a rotating shaft and a screen drum fixed on the outer circumference of the rotating shaft. One end of the rotating shaft is connected to the swing driving frame, and the other end is connected to the hinged supporting frame. It is connected with the other end of the rotating shaft, the funnel is fixed on the base and located under the screen cylinder, the belt conveyor is fixed on the base and located under the funnel, and the feeding chute is detachably arranged on the base and located on the swing drive frame Above; the structure design of the present invention is reasonable, and the connection between the swing drive frame and the hinged support frame and the rolling screen body can be used to realize the up and down swing of the rolling screen body, and a better screening effect can be obtained during the fly ash screening process, which can promote Improved screening efficiency.

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
