[0002] In the metallurgical material processing industry, dust pollution has always been an important factor affecting the working environment and workers' health, as well as improving production efficiency. Since a large amount of dust is generated during the crushing, screening, and transportation of metallurgical materials, this dust not only contains particulate matter that is harmful to the human body, but also causes occupational diseases if it is suspended in the air for a long time, and also causes serious damage to the surrounding environment.

[0003] Especially in the process of conveying metallurgical materials, these harmful particulate matter are more likely to escape into the air of the production environment. To avoid this situation, a dust prevention device for protective slag production is proposed to solve this problem. Utility Model Content

At the same time, the dust adhered to the conveyor belt is cleaned by the cleaning roller brush when passing through the cleaning roller brush, and further cooperates with the vacuum cleaner to absorb and collect the dust in the dust removal box through the connecting pipe, and then discharges it after subsequent treatment.

[0006] The conveying assembly includes a driving roller rotatably arranged at one end of a mounting bracket, a driven roller rotatably arranged at the other end of the mounting bracket, a conveyor belt wound around the outer circumference of the driving roller and the driven roller, a conveyor roller frame evenly arranged on the upper part of the mounting bracket for supporting the upper half of the conveyor belt, and a driving mechanism connected to the driving roller.

[0007] The cleaning roller assembly comprises a support shaft rotatably arranged on the dust removal box at the lower part of the conveying assembly, on which a cleaning roller brush rotating with the support shaft is arranged, and the cleaning roller brush is arranged in contact with the lower base surface of the conveying belt at the lower part.

[0008] The support shaft passes through the dust removal box and is transmission-connected with a driving device fixedly arranged at the lower part of the dust removal box, and a driving pulley for transmission is arranged at the end of the support shaft.

[0009] The eccentric mechanism comprises a rotating shaft rotatably arranged in the middle of the dust removal box, an eccentric block rotating with the rotating shaft is fixedly arranged on the rotating shaft, and the eccentric block is rotatably arranged on the lower base surface of the upper conveyor belt and matched with the upper conveyor belt.

The dust in the dust removal box is further collected and discharged uniformly after subsequent treatment by the vacuum cleaner through the connecting pipe. The two ends of the conveyor belt are supported by the driving roller and the driven roller respectively, and the middle part is supported by the conveying roller frame, so as to ensure that the material in the conveying process can move along the flow direction of the conveying roller frame, and avoid the conveyor belt being too straight so that the material falls from both sides of the conveyor belt to the dust removal box.
