Description

Technical Field

[0001] The utility model belongs to the technical field of glass production and relates to a self-cleaning device for a belt conveyor. Background Art

[0002] When conveying glass raw materials, belt conveyors are widely used to solve the problem of small-angle or horizontal transportation of raw materials. The problem of belt return has always been a difficult problem to be solved. At present, most measures such as adding multiple scrapers and brush rollers at the head wheel are adopted to solve the problem of belt return, but the effect is not ideal. Especially as the belt cracks and ages with the increase of service life, the role of the scraper and brush roller becomes smaller, and the return becomes more serious. The return material settles and accumulates under the entire belt, making it difficult to clean up; dust is scattered during the sinking process, resulting in a bad on-site environment. Utility Model Content

[0003] The purpose of the utility model is to provide a belt conveyor self-cleaning device in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to optimize the self-cleaning effect of the conveyor belt.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a self-cleaning device for a belt conveyor, characterized in that the belt conveyor includes a head wheel, a driving wheel and a belt, the self-cleaning device includes a dust cover, the dust cover wraps the head wheel, the lower end of the dust cover has a slag discharge port, the side of the dust cover has an avoidance port, the belt passes through the avoidance port, and an inclined return plate is provided between the avoidance port and the slag discharge port, a brush roller and a guide wheel are rotatably connected in the dust cover, the belt located below the axis of the head wheel passes through the upper part of the brush roller and the lower part of the guide wheel in turn, an air jet pipe parallel to the brush roller is arranged in the dust cover, a plurality of air jet holes are arranged on the air jet pipe, and the air jet holes face the brush roller; the brush roller and the head wheel rotate at a differential speed.

[0005] Furthermore, a pulley 1 is fixedly provided on the brush roller, a pulley 2 whose diameter is smaller than that of the pulley 1 is fixedly provided on the head wheel, and a traction belt is used to traction the pulley 1 and the pulley 2.

[0006] Due to the differential speed operation of the brush roller and the head wheel, the brush roller rotates relative to the belt to clean the residue adhered to the belt. At the same time, the setting of the brush roller and the guide wheel forms a concave area at the brush roller. The airflow acts on this area to flush the brush roller and the belt part passing through the guide wheel, so the residue on the brush roller and the belt can be cleaned in time. Finally, since the belt has multiple concave and convex parts at the brush roller and the guide wheel, it is equivalent to wrinkling the belt, which is beneficial to the cracking of the adhesion on the belt and the peeling.

[0010] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0011] like Figure 1 and Figure 2 As shown, the belt conveyor includes a head wheel 1, a driving wheel and a belt 2, and the self-cleaning device includes a dust cover 3, the dust cover 3 wraps the head wheel 1, the lower end of the dust cover 3 is provided with a slag discharge port 4, the side of the dust cover 3 is provided with an avoidance port, the belt 2 passes through the avoidance port, and an inclined return plate 5 is provided between the avoidance port and the slag discharge port 4, a brush roller 6 and a guide wheel 7 are rotatably connected in the dust cover 3, the belt 2 located below the axis of the head wheel 1 passes through the upper part of the brush roller 6 and the lower part of the guide wheel 7 in turn, an air jet pipe 8 parallel to the brush roller 6 is arranged in the dust cover 3, the air jet pipe 8 is connected to an air source, a plurality of air jet holes are arranged on the air jet pipe 8, and the air jet holes face the brush roller 6; the brush roller 6 and the head wheel 1 rotate differentially.

[0012] A pulley 1 is fixedly provided on the brush roller 6 , and a pulley 2 with a diameter smaller than that of the pulley 1 is fixedly provided on the head wheel 1 . A traction belt 9 is used to traction the pulleys 1 and 2 .

[0013] Due to the differential operation of the brush roller 6 and the head wheel 1, the brush roller 6 rotates relative to the belt 2 to clean the residue adhered to the belt 2. At the same time, the setting of the brush roller 6 and the guide wheel 7 forms a concave area at the brush roller 6. The airflow acts on this area to flush the brush roller 6 and the belt 2 passing through the guide wheel 7, so as to clean the residue on the brush roller 6 and the belt 2 in time. Finally, since the belt 2 has multiple concave and convex parts at the brush roller 6 and the guide wheel 7, it is equivalent to wrinkling the belt 2, which is beneficial to the cracking of the adhesion on the belt 2 and the peeling.

[0014] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
