Abstract

The invention belongs to coal mine dust suppression equipment, particularly relates to a dust suppression device and solves the problem that dust causes damage to an operating environment of a coal mining face during coal mining. The dust suppression device comprises a dust catcher net disposed in a return airway of the coal mining face and a circular water curtain; the dust catcher net is provided with a passenger door; nozzles are disposed on the windward side of the dust catcher net; the circular water curtain comprises a fixing device and a body fixed with the fixing device; a quick connector connected with a water pipe is disposed on the body; a plurality of mist nozzles are evenly distributed on the peripheral side of the body; each mist nozzle comprises a nozzle cap serving as a nozzle frame, a spiral core arranged inside the nozzle cap and a liquid incoming distribution plate disposed at a liquid inlet of the nozzle cap; each liquid incoming distribution plate is evenly provided with a plurality of liquid incoming pores; the spiral core is a trapezoidal cylinder; the outer side of each spiral core is provided with double spiral grooves. The dust suppression device has good effect of dust suppression.

Description

technical field [0001] The invention belongs to coal mine dust suppression equipment, in particular to a dust suppression device. Background technique [0002] With the continuous improvement of the mechanical level of various production links such as coal mining, the output of raw coal continues to increase, and the absolute amount of dust generated increases, which has caused great harm to the operating environment of the mining face. Combined with the actual situation of our mine and the existing dust-proof facilities, the dust concentration in the return air flow of the mining face cannot be well reduced. By adding the technical means of dust-proof water curtain, the purpose of dust reduction is mainly achieved by spraying water curtain with linear water curtain, but the installation of linear water curtain downhole is cumbersome and not suitable for carrying, and the cost is relatively high. Contents of the invention [0003] The invention provides a dust reducing de...
