Water circulation type dust removal spraying device based on underground operation in coal mine

Abstract

The invention discloses a water circulation type dust removal spraying device based on an underground operation in a coal mine. The water circulation type dust removal spraying device comprises a shield mechanism, and is characterized in that a separation mechanism is arranged behind the shield mechanism; an extrusion mechanism is arranged above the separation mechanism; the shield mechanism is connected with the separation mechanism through a pipeline; the separation mechanism is connected with the extrusion mechanism through a pipeline; the shield mechanism comprises a shield machine base; a shield shaft is arranged in the middle of the shield machine base; a plurality of elastic rods are arranged outside the shield shaft in a surrounding mode; the other ends of the elastic rods are all connected with shield assemblies; each shield assembly comprises a roller; shield teeth are arranged outside the roller, and a rotating shaft is arranged in the roller; a round sleeve is hinged to the lower portion of the rotating shaft; a plurality of sets of fixing sleeves are arranged on the outer portion of the round sleeve in a surrounding mode; the interior of each fixing sleeve is in piston connection with a sharp strip; and a sliding nail is arranged on the surface of each sharp strip. The device has the characteristics of improving the quality of mined coal mine and having strong capability of coping with mine disasters.

Description

technical field [0001] The invention relates to the technical field of coal mine underground operations, in particular to a water circulation dust removal and spraying device based on coal mine underground operations. Background technique [0002] A large amount of dust will be produced in the process of coal mining. With the continuous improvement of the mechanization of coal mine production, the dust content in the coal mine roadway is getting higher and higher, filling the entire operation site, and flying in the entire roadway, which not only pollutes the environment, but also It has seriously affected the health of coal mine workers, and coal workers have become a high-risk group susceptible to pneumoconiosis. Therefore, dust suppression in coal mine roadways is very necessary. [0003] The existing water circulation dust removal spray device for underground coal mine operation has poor spray dust removal effect, and cannot adapt to the amount of surrounding dust to con...

AI Technical Summary

Problems solved by technology

[0003] The existing water circulation dust removal spray device for underground coal mine operation has poor spray dust removal effect, and cannot adapt to the amount of surrounding dust to control water content, resulting in the possible combination of water mist and dust to form sludge, which affects the life of the device. At the same time, in the event of a mine accident The device is also unable to provide assistance for construction rescue
