Description

Technical Field

[0001] The utility model relates to the technical field of mine dust reduction, in particular to a dust reduction device for mine material loading. Background Art

[0002] After the ore is crushed, it needs to be conveyed to the transport vehicle by the conveyor belt, and the transport vehicle will transport the ore to the designated stockpile site. Because the crushed ore contains a lot of dust and debris, when the conveyor belt unloads the ore into the transport vehicle, a lot of crushing will also occur. The dust will spread into the air, polluting the processing environment, endangering human health, and causing occupational diseases. In particular, when the ore dust containing free silica floating in the mine air exceeds a certain value, it will pose a great threat to the health of miners, such as pneumoconiosis and coal lung disease.

[0003] During production operations, water is generally used as a dust removal medium. When mining stones or crushing minerals, water is used to wet the materials to cool the equipment and suppress the generation of dust.

[0004] However, there are still the following disadvantages: the device sets a sprinkler on the conveyor belt to cool down and remove dust from the ore, but when the ore is dumped into the transport vehicle, the ore is suspended and tumbles, which easily causes the dust in the gaps between the ore to diffuse into the air, and there is a lack of targeted dust reduction devices. Therefore, we propose a dust reduction device for ore loading to solve this problem. Utility Model Content
