Abstract

The invention particularly relates to a mining spraying and dust settling device capable of automatically regulating an atomization grain size, solving the problems that when the existing spraying and dust settling device settles tiny dust, the dust settling efficiency is poor, and water resources are seriously wasted. A grain size adjusting nozzle comprises a barrel and a nozzle body, wherein a metal guide sleeve is arranged in the barrel, an electromagnetic coil is arranged outside the metal guide sleeve, a permanent magnet is arranged in the metal guide sleeve, the permanent magnet is connected with a push rod, the nozzle body is provided with a pressure sensor and a nozzle valve, a reset spring sleeves the push rod, output ends of a dust grain size sensor and the pressure sensor are connected with input ends of a central processor, an output end of the central processor is connected with an input end of an amplifier, and an output end of the amplifier is connected with input ends of a flow regulation electromagnetic valve and a pressure regulation electromagnetic valve, and the electromagnetic coil of the grain size adjusting nozzle. According to the mining spraying and dust settling device, automatic control and regulation for spraying and dust settling are realized, and real-time detection is performed on dust grain size.

Description

technical field [0001] The invention relates to a coal mine dust suppression device, in particular to a mine spray dust suppression device with automatic adjustment of atomization particle size. Background technique [0002] Coal mining is one of the important basic industries, and the number of workers engaged in coal mining is large, occupying the first place among various mining industries. Miner's pneumoconiosis is the main occupational disease of coal workers. It not only affects the production and development of coal enterprises, but also seriously endangers the health and life of workers. Therefore, in this case, spray dust suppression is particularly important. [0003] Although the existing spray dust suppression system is automated and can adjust the flow rate according to the dust concentration, it has been proved by experiments that the high efficiency of wet dust suppression is closely related to the particle size distribution of droplet atomization and dust par...
