Description

Technical Field

[0001] The utility model relates to the technical field of non-metallic mineral processing, in particular to a dust recovery device for manufacturing non-metallic mineral products. Background Art

[0002] Non-metallic minerals are minerals that lack a metallic or semi-metallic luster, are colorless or pale in various shades, and have poor electrical and thermal conductivity. During the processing and manufacturing of non-metallic minerals, dust recovery devices are often used to remove the dust generated during processing to prevent it from affecting the subsequent processing of non-metallic mineral products. Traditional dust recovery directly removes the dust by blowing it away with strong winds or extracting it through suction devices. Since some materials in the dust produced by non-metallic mineral product manufacturing are recyclable, direct removal results in a waste of non-metallic mineral resources. Direct extraction can easily cause some non-metallic minerals to be sucked out along with the dust, impacting the environment.

[0003] In order to improve the above-mentioned disadvantages, the utility model patent with application number 202221941813.7 in the public technology discloses a dust recovery device for the manufacture of non-metallic mineral products, including a collection device for collecting dust after filtering through a filter part, and a cleaning part is provided at the lower end of the collection device, and the cleaning part cleans the dust accumulated inside the collection device. The collection device includes an aggregate chamber. Although the gas containing dust particles can enter the interior of the collection device, as the air pressure continues to flow, when the dust particles pass through the filter part, the filtered part separates the dust particles from the gas and accumulates them at the bottom of the collection device. At the same time, the negative pressure device can make the airflow flow in the opposite direction to flush the dust adsorbed on the filter element of the filter part, thereby extending the service life of the filter element.

[0004] However, in order to clean the dust on the filter element and extend its service life, the device needs to be equipped with a negative pressure device with a back-blowing function, which is relatively expensive. In addition, during the back-blowing cleaning operation, dust explosions are likely to occur inside the aggregate bin, and some smoke and dust will be discharged to the outside from the feed pipe, causing secondary pollution to the surrounding environment. Its practical performance needs to be improved. Utility Model Content

When the auger rod inside the cleaning part 2 rotates, the rotating rod 9 can rotate concentrically. The setting and rotation principle of the auger rod in the cleaning part 2 are the same as the connection relationship and operation principle of the cleaning part and the auger rod in the comparative document, so they will not be described in detail. A disc 10 is fixed to the top of the rotating rod 9, and a convex tooth ring 11 is concentrically fixed to the upper surface of the disc 10.

Then the two horizontal bars 15 revolve around the horizontal cylinder 13 as the center and perform intermittent movement in the horizontal direction. The cleaning brush 16 provided on the outer wall of the horizontal bar 15 will clean the outer wall of the filter element 6 without the help of a negative pressure device with a backblowing function, so as to reduce the cost of the device. In addition, there is no need to worry about the dust explosion caused by backblowing during the cleaning process, and it will not cause secondary pollution to the surrounding environment, and the practical performance is enhanced.
