Spraying mechanism for fog gun machine

Abstract

The invention relates to the technical field of fog gun machines, and discloses a spraying mechanism for a fog gun machine. The spraying mechanism comprises a gun barrel body, one end of the gun barrel body is fixedly connected with a jet sleeve, the jet sleeve comprises a left half sleeve and a right half sleeve, the left half sleeve and the right half sleeve are closed in a butting mode to formthe jet sleeve, the jet sleeve is internally provided with a jet channel, the jet channel is internally provided with an atomization device, and the atomization device is used for axially spraying atomized beads into the jet channel. According to the spraying mechanism, the atomization device is arranged in the jet channel, on the one hand, the flow speed of jet gas entering the jet channel from the gun barrel body can be further increased under the situation of decreasing of a sectional area, thus initial supplied energy of the jet gas can be reduced, on the other hand, atomization spraying is conducted in the jet channel, then atomized fog drops can be directly jetted out along with the jet gas through the fluidization action of the jet gas in the jet channel on the fog drops, the spraying effect of the spraying mechanism is better, the loss of water droplets during jetting out of the jet sleeve is reduced, and water resources are saved.

Description

technical field [0001] The invention relates to the technical field of fog cannons, in particular to a spraying mechanism of fog cannons. Background technique [0002] Fog cannons are mostly used for dust reduction in urban streets, construction sites, open-air material storage yards, mining and other high-dust environments. After high-pressure water is atomized by atomizing nozzles, it is blown into the environment by an axial flow fan. It has a range Long distance and high coverage. [0003] At present, the fog cannon machines are equipped with the atomizing nozzles on the edge of the barrel in a circular distribution, and the facing part of the atomizing nozzles is outward, and most of them are inward to the barrel, combined with the middle of the barrel from the axial flow fan. The high-speed jet gas drives the droplets to blow to the distance. Since the atomizing nozzle and the jet gas are set separately, on the one hand, the water mist sprayed by the atomizing nozzle...
