AI Technical Summary
In the existing coal dust removal and dust removal conveying devices under the coal mine, the content of cinder in the sewage tank is relatively large and requires frequent manual cleaning, which increases the labor intensity of construction workers.
Design a coal dust separation and conveying device, including a cyclone dust collector, a collection box and a secondary dust collector. The cyclone dust collector absorbs coal dust during drilling and separates cinders from coal dust gas. The cinders are collected in the collection box. After passing through the secondary dust collector, the coal dust gas is mixed with the dust removal water to form coal dust sewage to prevent cinders from entering the sewage tank.
By separating cinder and coal dust gas, cinder is prevented from entering the sewage tank, reducing the frequency of manual cleaning and reducing the labor intensity of construction workers.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mine equipment, in particular to a coal dust separation and transportation device. Background Art
[0002] During the drilling operation in coal mines, coal dust is inevitably generated. These tiny coal dust particles not only pose a threat to the health of construction workers, but may also cause safety accidents such as explosions. Therefore, effective dust removal of coal dust in coal mines is of great significance to ensuring the safety of construction workers and improving coal mine production efficiency.
[0003] like Figure 1 As shown, the existing coal dust removal and conveying device for underground coal mines mainly includes a dust collector installed on a base 1, and a sewage tank 5 connected to the dust collector. The dust collector has a dust suction port 11. When in use, the coal dust generated during the drilling construction process is first sucked into the dust collector through the dust suction port 11, and the coal dust is atomized by the dust removal water provided by the underground water pipe to form coal dust sewage. Finally, the coal dust sewage is transported to the sewage tank 5 for storage, thereby completing the dust reduction treatment of the coal dust generated during the drilling construction process, reducing the harm of coal dust to the life safety of construction personnel, avoiding safety problems such as explosion caused by coal dust, and improving the production efficiency of the coal mine.
[0004] It can be seen that when the above device is used, the coal dust generated during the drilling construction process is sucked into the vacuum cleaner and atomized and dusted, and then the coal dust sewage generated by the atomized dust is discharged into the sewage tank. However, in actual application, the coal dust generated during the drilling construction process includes not only small particles of coal dust gas, but also large particles of coal slag, which are atomized and stored in the sewage tank, resulting in a large amount of coal slag in the sewage tank. After the coal slag is settled, it needs to be cleaned frequently by manual labor, which increases the labor intensity of the construction workers. Utility Model Content
[0005] The utility model provides a coal dust separation and conveying device to solve the technical problem that the coal slag content in the sewage tank of the coal dust treatment device in the prior art is large, frequent manual cleaning is required, and the labor intensity of construction workers is increased.

[0011] A collecting box, which is mounted on the base and connected to the cyclone dust collector to collect the transported coal slag;
[0012] A sewage tank is connected to the secondary dust collector to store the coal dust sewage delivered by the secondary dust collector.
[0013] The beneficial effects of the coal dust separation and transportation device provided by the utility model are as follows: by setting a cyclone dust collector and connecting it to a collection box and a secondary dust collector, the cyclone dust collector is used to absorb the coal dust in the drilling process, and the coal slag and coal dust gas in the coal dust are separated and sent to the collection box and the secondary dust collector respectively, and then the coal dust gas is transported from the secondary dust collector into the sewage tank and mixed with the dust removal water to form coal dust sewage, thereby avoiding the occurrence of coal slag entering the sewage tank, thereby reducing the frequency of manual cleaning of the sewage tank and reducing the labor intensity of construction personnel. In summary, the utility model effectively solves the technical problem that the coal slag content in the sewage tank of the coal dust treatment device in the prior art is large, and frequent manual cleaning is required, which increases the labor intensity of construction personnel.
