Detailed Description

Structure and working principle of the utility model

As shown in fig. 1: a wind and water linkage spraying device for a driving face comprises a high-pressure wind pipe 1, a wind pipe joint 2, a high-pressure water pipe 3, a water pipe joint 4, a wind and water synthesis pipe 5 and a mixing nozzle 9, wherein a wind pipe 10 is arranged inside the wind and water synthesis pipe 5, the high-pressure wind pipe 1 is connected with the wind pipe 10 through the wind pipe joint 2, and the high-pressure water pipe 3 is connected with the wind and water synthesis pipe 5 through the water pipe joint 4; the water faucet comprises a blast nozzle 6, a water nozzle 7 and an anti-backflow plate 8, wherein the water nozzle 7 is arranged outside an aqueous vapor synthesis pipe 5, the water nozzle 7 is communicated with the aqueous vapor synthesis pipe 5, the blast nozzle 6 is connected with an air pipe 10, a nozzle opening of the blast nozzle 6 penetrates through the aqueous vapor synthesis pipe 5 and extends into the water nozzle 7, a nozzle opening central shaft of the blast nozzle 6 is overlapped with a nozzle opening central shaft of the water nozzle 7, and the anti-backflow plate 8 is further arranged in the water nozzle 7.

The working principle of the utility model is as follows: the special nozzle is installed on the water-air synthesizing pipe 5, make wind, the water is integrative and realize independent passage, tuyere 6 connects tuber pipe 10, water injection well choke 7 connects water-air synthesizing pipe 5, install additional at water injection well choke 7 and prevent the anti-backflow board 8, prevent that anti-backflow board 8 can only one-way passage, prevent that the wind pressure from leading to the water backward flow in water-air synthesizing pipe 5 with water pressure, utilize tuyere 7 to carry out the air water mixed atomization with fast-speed air flow and water injection well choke 7 play water in mixing nozzle 9, form than the more tiny water smoke of traditional spraying, this kind of water smoke is a thin fog group that can float the removal, this kind of thin fog group is at aerial residence time than traditional spraying greatly increased, increase the area of water smoke dust fall, have better adsorption to the dust, thereby reach good dust fall effect.

The size of the mixing nozzle 9 is variable and typically may be in various sizes, 1/4 inches, 1/2 inches, 1 inch, 1.5 inches, to meet the spray requirements of different operating environments.

The water pressure of the high-pressure water pipe 3 is 1 MP-2 MP, the air pressure of the high-pressure air pipe (1) is 1-2 times of that of the high-pressure water pipe 3, and the atomization effect is optimal when the air pressure of the high-pressure air pipe is 1.2 times of that of the high-pressure water pipe.
