Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0014] A dust-proof water curtain for mines, which is characterized in that it includes two horizontal water spray pipes arranged in parallel and a longitudinal connecting pipe connected between the two water spray pipes, and a number of self-rotating nozzles are evenly arranged on the horizontal water spray pipes , the self-rotating nozzle is provided with a number of spray holes, and the spray holes are uniformly inclined clockwise or counterclockwise in the horizontal direction, and the longitudinal connecting pipe is provided with a water inlet joint. The shape of the horizontal spray pipe is arched or straight. The number of the self-rotating nozzles is 6-9.

[0015] This kind of dust-proof water curtain for mine can spray two water curtains at the same time, the nozzle can be rotated, and a larger area of ​​water curtain can be sprayed,...

Abstract

An underground dust-proof water curtain is characterized in that it includes two horizontal water spray pipes arranged in parallel and a longitudinal connection pipe connected between the two water spray pipes, and several self-rotating nozzles are evenly arranged on the horizontal water spray pipes, The self-rotating nozzle is provided with a number of spray holes, and the spray holes are uniformly inclined clockwise or counterclockwise in the horizontal direction, and the longitudinal connecting pipe is provided with a water inlet joint. This kind of underground dust-proof water curtain can spray two water curtains at the same time, and the nozzle can be rotated to spray a larger area of ​​water curtain, so that the water mist can better cover the roadway, greatly reducing the coal dust passing rate, and greatly reducing the traffic flow of the roadway. The inner coal dust concentration is better to purify the air in the underground roadway.

Description

technical field [0001] The invention relates to the field of mine dust prevention, in particular to a mine dust prevention water curtain. Background technique [0002] Dust prevention in coal mines has always been the focus of the work of "one pass, three defenses". Effective dust prevention work can not only prevent underground workers from inhaling harmful dust, but also prevent coal dust explosions from happening. Installing dust-proof water curtains in underground roadways is a common dust-proof means. However, although the water curtains ejected from existing dust-proof water curtains cover the entire section of the roadway, the gap between the water flows ejected from the nozzles is relatively small. Large, the dustproof effect of the water curtain is not ideal. Contents of the invention [0003] The invention aims at the problem of poor dust-proof effect of the underground dust-proof water curtain in the prior art, and proposes a mine-used dust-proof water curtain....
