Anti-seepage liquid spraying equipment for basement drainage

Abstract

The invention relates to the technical field of basement mining air environment protection, in particular to anti-seepage liquid spraying equipment for basement drainage. According to the technical scheme, the paint spraying device comprises a paint storage box and a spraying head, a rotating rod and a stirring rod are arranged in an inner cavity of the paint storage box, a direction adjusting mechanism is arranged at the top of a mounting box, a flow control mechanism is arranged in the spraying head, a clamping and fixing mechanism is arranged on one side of the spraying head, and a driving mechanism is arranged at the top of the paint storage box. According to the direction adjusting mechanism, the spraying direction can be automatically adjusted, and large-range spraying is achieved; the clamping and fixing mechanism can fix the spraying head, so that manual and automatic spraying is integrated, and the working intensity of basement anti-leakage workers is greatly reduced; the flow control mechanism can control the liquid spraying flow of the spraying head, and the content of harmful substances with high water solubility in the basement in the air is reduced through the liquid spraying equipment. The method is mainly applied to protecting the air environment of mining basements.

Description

technical field [0001] The invention relates to the technical field of basement mining air environmental protection, in particular to an anti-seepage liquid spraying device used for basement drainage. Background technique [0002] Mining by building a basement can greatly avoid serious damage to the ground environment during the mining process. However, in the mine cave in the basement, the internal air environment contains a lot of water-soluble harmful gases, such as sulfur dioxide, hydrogen sulfide, and hydrogen sulfide. Nitric oxide, ammonia and other toxic and harmful substances, in the process of basement drainage, the above water-soluble harmful substances will dissolve in water, seep into the water in the mining basement, and discharge to the bottom water along the basement drainage, causing environmental pollution, and in the basement When the above-mentioned harmful substances remain in the air environment, it will also have a huge impact on the health of the staff...

AI Technical Summary

Problems solved by technology

[0002] By building a basement for mining, it can greatly avoid serious damage to the ground environment during the mining process, but in the mines in the basement, the air environment inside contains many water-soluble harmful gases, such as sulfur dioxide, hydrogen sulfide, di Toxic and harmful substances such as nitrogen oxides and ammonia. During the drainage process of the basement, the above-mentioned water-soluble harmful substances will dissolve in water, leak into the water in the mining basement, and discharge to the underground water along the drainage of the basement, causing environmental pollution. When the above-mentioned harmful substances remain in the air environment, it will also have a huge impact on the health of the staff. At present, water spray is mainly used to absorb the harmful substances and purify the air environment in the mining basement for the above-mentioned water-soluble harmful substances.

According to the literature "Types and Hazards of Toxic and Hazardous Substances in Mine Operation Sites", there are many types of toxic and harmful substances in mine operation areas. In addition to the above-mentioned water-soluble toxic and hazardous substances, they also contain explosive gases such as methane etc. Therefore, it is urgent to protect the air environment in mining operation areas such as basements
