Embodiment Construction
[0016] Below in conjunction with figure, the present invention is described in further detail:
[0017] An automatic mine surfactant adding device according to the present invention includes a water supply system, a mixing system and a pneumatic system. Wherein, the water supply system is connected in parallel on the pipeline of the underground static pressure water pipe, and the water supply system is responsible for introducing the static pressure water in the static pressure water pipe to the parallel branch composed of the water supply system. The mixing system is responsible for automatically adding surfactant in proportion to the water supply system of the parallel branch to form a surfactant solution of the required concentration; the pneumatic system is used to push the mixed surfactant solution back and mix it into the static pressure water pipe In the pipeline, the purpose of dust removal by using static pressure pipeline and solution is completed.

The invention discloses a mining surfactant automatic adding device which comprises a water supply system, a mixing system and a pneumatic system. The water supply system is connected in parallel to a pipeline of an underground static pressure water pipe; the mixing system and the pneumatic system are respectively connected to the water supply system; the pneumatic system is positioned on the pipeline between the mixing system and the output end of the water supply system; and the input end of the pneumatic system is communicated with an underground compressed air pipeline. In the integral system, the existing underground compressed air pipeline is utilized to provide power to complete the automatic mixing process of static pressure water and a surfactant, so that the process of adding surfactant solution into the underground static pressure pipe is implemented, the dust removal effect is greatly improved and the dust removal reliability is improved. The mining surfactant automatic adding device has the advantages of simple structure, reliable performance and convenience in installation and is very suitable for use for removing dust in mines such as a coal mine, a metal mine and the like.
Description
technical field [0001] The invention relates to a mine-used surfactant automatic adding device, which belongs to the technical field of mines. Background technique [0002] With the rapid development of my country's industry and society, the demand for mineral resources is increasing. As the basic energy of our country, coal plays a pivotal role in the national economy. According to statistics, coal accounted for 76% of primary energy consumption in 1990, 70% in 2000, and is expected to still account for 60% by 2050. With the continuous increase of coal mining intensity, the incidence of production accidents is also increasing. Among them, underground dust is one of the important causes of coal mine accidents. [0003] The harm of dust, on the one hand, is manifested as: the quality of the atmosphere, water, and surrounding environment is reduced, visibility is deteriorated, the service life of mechanical equipment is reduced, and wear is serious. healthy. As of 2002, m...
