Abstract

The invention provides a spraying device for dust fall. The spraying device comprises a circular air pipe, a motor, a circular diameter-variable air pipe and a spraying mechanism, wherein the large-diameter end of the circular diameter-variable air pipe is connected to one end of the circular air pipe, the small-diameter end of the circular diameter-variable air pipe is connected with the spraying mechanism, the motor is a double-shaft synchronous motor, and impellers are respectively connected to rotating shafts on both ends of the double-shaft synchronous motor. The spraying device has the characteristics of thin spraying particle, large mist spraying area, wide range and the like, the dust control range can be changed when a dust source changes, the purposes of onsite purification and secondary vacuum dust removal are realized, and the dust fall effect is obvious.

Description

technical field [0001] The invention relates to the technical field of mining operations, in particular to a spraying device for reducing dust. Background technique [0002] In mine production operations, coal shearers or roadheaders will generate a large amount of dust when cutting coal (or rock mass), and the dust concentration is as high as 3000-5000mg / m 3 , the high concentration of dust not only affects the normal production of the mine, but also causes a major hidden danger of the mine dust explosion, and directly endangers the health of the mine workers. For high concentrations of dust, the main measures are: [0003] (1) Internal and external spraying of mining machinery: Because the nozzle is directly installed on the cutting head, it is easy to block the nozzle when cutting coal, making the spraying measures useless and ineffective. [0004] (2) Dust source tracking spray dust suppression system: The feature of this system is that, through the transmitter and rec...
