The rotating shaft 13 has a length of 50-60mm and a diameter of 2mm, and has threads engraved in the region of 10mm at the left end and in the region of the right half of the rotating shaft, and nuts are disposed on the regions provided with the threads and are adapted to the threads, so that the nuts are fastened to prevent the rotor 10 from falling off during operation. The bracket 30 is L-shaped, the height of the bracket is 20-30mm higher than that of the liquid supply box 20, the width of the bracket is 10-20mm, and a round hole with the diameter of 5mm is arranged on the upper part of the bracket and is 5-10mm away from the top end; the hollow screw 31 has a length of 10-20mm, an outer diameter of 5mm and an inner diameter of 0.1-0.5mm larger than the diameter of the rotating shaft 13; the hollow screw 31 is installed in the top circular hole of the bracket 30 and is locked with a nut.

The speed-adjustable fan 40 is arranged at a position 50-200mm away from the foaming rotor 10 in the axial lead direction right opposite to the foaming rotor, and blows air perpendicular to the foaming disc 11, and the air speed is controlled within the range of 1-20 m/s. And pouring a proper amount of foaming liquid into the box to submerge the foaming holes, and then starting the fan. The foaming rotor 10 rotates rapidly under the action of certain wind power, and the generated bubbles fly into the air immediately to capture dust, and the dust is settled on the ground after being broken, so that a better dust removal effect is realized. In the process of removing dust on the working face of coal mine excavation, blasting or mechanical cutting and the like are generally adopted in the process of underground mine excavation, and air supply is carried out in front of the working face to ensure the safety of constructors and avoid safety accidents such as gas explosion, toxic and harmful gas poisoning and the like. And the dust that appears in the excavation process can also spread to other places along with the wind current, has so not only polluted the working face, also influences the production of other drifts simultaneously. Therefore, the common practice of many rock mines is to stop production after blasting, withdraw all personnel on the working face, and resume production after the blast smoke is dissipated; during coal mining, a water curtain is usually arranged in a return air roadway to intercept dust and prevent the dust from spreading. And on-site water curtain dust removal effect is comparatively general, not only needs a large amount of water resources, causes the tunnel bottom plate ponding serious moreover easily, hinders personnel's equipment to pass through, has caused huge potential safety hazard. And some coal mines adopt an air curtain technology for dust removal, namely, a section of air curtain is arranged at a certain position of an air return roadway or an air inlet roadway to intercept dust and prevent the dust from diffusing to other surrounding areas. According to the current field application situation, the air curtain dust removal technology not only uses huge air quantity, but also consumes a large amount of electric power, and has common effect. In order to achieve the purpose, the dust removal bubble generator of the utility model replaces the water curtain or the air curtain on the air return roadway or the air inlet roadway with countless single bubbles to form a bubble group or a bubble curtain to purify dust. First, a bubble curtain is arranged at a location from the mining face according to the site requirements. After a plurality of assembled dust removal bubble generators are installed, at a certain distance from the rear of a coal mine excavation working face, the foam generators are arranged at intervals of 500mm along the peripheral line of the roadway section at the position, and the foam plates 11 are perpendicular to the roadway section, so that bubbles generated by the foam generators can fly to the dust spread out, and meanwhile, the bubbles can fly in the air for a long time, and more dust is captured. Secondly, according to the actual situation of the dust concentration on site, the number of rows of bubble generators can be increased, the distance between every two rows is 0.5-1m, and three rows are arranged in the scheme, so that the density and the number of bubbles are increased, and the dust removal effect is enhanced. In view of the explosion hazard of coal dust, the speed-adjustable fan can be replaced by an explosion-proof fan or the compressed air on site can be used for providing wind power. Then the fan or the air pressure valve is started, the foaming rotor 10 rotates rapidly under the blowing of certain wind power, and generates a large amount of bubbles to fly in the roadway, and at the moment, dust reaching the bubble curtain can be basically intercepted or captured and settled on the ground together with the destruction of the bubbles, so that pollution in other places is avoided. In recent years, air pollution and haze weather of big cities in China increase, and building dust is an important pollution source of the big cities, and is caused by the building dust. When dust is removed on a construction site, generally, measures such as wet operation, canvas covering, spraying and sprinkling are adopted in addition to means of building dust emission, and the effect is obviously improved. The water consumption of the wet operation is large, and the effect is general. In order to better realize the dust removal effect and save water resources, an air purification technology combining spraying and sprinkling with bubble dust removal can be adopted on some construction sites. First, several dust removing bubble generators are arranged in sequence along the dust generating point. The dust-removing bubble generators are arranged along the height of 1.5-2m from the ground on site and every 1-2m, or the density of the arrangement is increased according to the actual requirement on the site. Next, a liquid supply device is used to supply the foaming liquid into the liquid supply box 20, so that a certain amount of foaming liquid is maintained in the box. Thirdly, when dust removal is needed, the fan of the bubble generator is started to blow the foaming rotor 10, so that bubbles continuously fly out of the foaming disc 11 to collect dust flying in the air. Meanwhile, the bubbles falling on the ground without being destroyed cover the dust source, and further suppress the flying of dust. The visible bubbles can capture the raised dust in the air by dedusting, and can cover the dust generating source at the same time, thereby achieving double effects.

The working principle is as follows: first, the foaming disk 11 and the wind kinetic energy converter 12 are sequentially screwed with the rotating shaft 13, and then one side of the wind kinetic energy converter 12 is fastened with a nut, thereby assembling a foaming rotor 10. Next, the hollow screw 31 is installed in the circular hole at the upper end of the bracket 30, and is locked and fixed by a nut, then the foaming rotor 10 is inserted into the hollow screw 31 on the bracket with one end thereof positioned at one side of the foaming disc 11, and is then locked by a nut, so as to prevent the foaming rotor from falling off during the rapid rotation process, and meanwhile, the foaming rotor is vertically placed into the liquid supply box 20, and the disc surface with 2/3 is exposed out of the box. The hollow screw and bracket act as a support and fixation axis for the foaming rotor 10 so that the foaming rotor can rotate around the gap screw. Thirdly, the air outlet of the speed-adjustable fan 30 is aligned to the wind kinetic energy converter 12 on the foaming rotor 10, and the rotating speed of the foaming rotor is controlled by adjusting the distance between the speed-adjustable fan and the foaming rotor and enabling the wind flow to be perpendicular to the surface of the foaming disk. Fourthly, a proper amount of foaming liquid is poured into the liquid supply box 20 to maintain a certain liquid level, so as to ensure that the foaming holes on the foaming tray 11 are submerged in the liquid. Finally, the speed-adjustable fan 30 is started, the foaming rotor 10 can rotate rapidly under the action of certain wind power, and the foaming liquid carried by the foaming holes on the foaming disc 11 is blown by the wind power to foam and is separated from the foaming disc 11 to fly into the air, meets dust in the air, is adhered, intercepted and captured, then is destroyed, and is settled to the ground together, so that the purposes of removing dust and purifying air are achieved.
