Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection engineering, in particular to a dust reduction device for environmental protection engineering. Background Art

[0002] After searching the patent document with the announcement number CN218774509U, water is delivered to the atomizing nozzle through the cooperation of a water pump and a water delivery pipe, and the water is sprayed out to reduce dust in the air carrying dust, and the air after dust reduction is discharged from the box through the air outlet pipe, and then the water after dust reduction is collected and filtered for repeated use next time;

[0003] According to the patent document, when the air is dust-reducing, the air will carry a large amount of moisture when passing through the water mist. When the air carrying moisture in the above structure passes through the air duct, a large amount of water will be sent out, and some water will gather on the inner wall of the air duct, which may cause a large amount of dust to accumulate in the air duct, while the moisture falling back into the box will be very small. As a result, this dust reduction method is relatively inefficient and will also cause water waste. Utility Model Content

The air with dust is sucked into the dust filtering mechanism 2 by the air outlet pipe 11 and the air inlet pipe 12. In this process, the dust in the air is preliminarily removed by the first electrostatic adsorption ring 13 and the second electrostatic adsorption ring 14, and the filtered and dust-removed air is discharged from the center of the air outlet pipe 11;

[0033] In this embodiment, the circulation mechanism 3 includes a driving pipe 33, a water collection cover 31 is fixed to the upper end of the driving pipe 33, a wind supply blade 32 is fixed to the outer side of the water collection cover 31, a water suction cylinder 34 is fixed to the lower end of the driving pipe 33, and the water collection cover 31, the driving pipe 33 and the water suction cylinder 34 are all hollow structures and connected to each other, a gear ring 37 is fixed to the upper side of the outer side of the water suction cylinder 34, three transmission gears 36 are meshed on the outer side of the gear ring 37, and a suction impeller 3 is arranged on the outer side of the transmission gear 36. 5. The suction impeller 35 is welded by an outer ring, an inner ring and a plurality of blades. The plurality of blades are circumferentially distributed between the outer ring and the inner ring. A T-shaped ring track is provided on the outer ring. The inner wall of the inner ring is provided with teeth meshing with the transmission gear 36. A water outlet is provided at one end of the air supply blade 32 away from the water accumulation cover 31, and the water outlet is communicated with the hollow structure of the water accumulation cover 31. A water inlet is provided at the lower end of the water suction cylinder 34. The bottom of the water suction cylinder 34 is connected to the rotating part of the driving motor 4. The rotating part of the driving motor 4 is used to drive the water suction cylinder 34 to rotate, and the water suction cylinder 34 drives the driving pipe 33 to make the water collection cover 31 and the air supply blade 32 rotate inside the air outlet pipe 11, and the water inside the dust filter mechanism 2 is sucked in through the water inlet of the water suction cylinder 34 through the water outlet hole of the air supply blade 32 under high-speed rotation, and is transported by the water suction cylinder 34, the driving pipe 33 and the water collection cover 31 and thrown out from the water outlet hole at the end of the air supply blade 32, and then the thrown water hits the inner wall of the air outlet pipe 11 to form droplets, part of the droplets follow the air and fly into the air, and the other part is collected on the inner wall of the air outlet pipe 11 and falls back into the dust filter mechanism 2, and at the same time, when the driving pipe 33 rotates, the transmission gear 36 is driven to rotate through the gear ring 37, and then the three transmission gears 36 drive the entire suction impeller 35 to rotate through the teeth of the inner ring, and at this time, the external air is sucked in from the gap between the air outlet pipe 11 and the air inlet pipe 12 through the rotation of the suction impeller 35.

[0034] In this embodiment: the dust filtering mechanism 2 includes a water collecting cylinder 21, and an annular groove cooperating with the outer ring T-shaped ring rail is opened on the upper side of the inner wall of the water collecting cylinder 21, and four support legs 24 are fixed to the bottom side of the inside of the water collecting cylinder 21, and an annular filter plate 23 for removing dust in the passing air is fixed on the upper end of the support leg 24, and a support seat 22 for supporting the transmission gear 36 is fixed on the top of the annular filter plate 23, and the lower end of the air outlet pipe 11 and the top of the support seat 22 are both in contact with the top and bottom of the inner ring of the suction impeller 35. The air sucked into the water collecting cylinder 21 passes through the annular filter plate 23 for secondary filtration and dust removal, and then flows from the inside of the annular filter plate 23 through the top of the support seat 22 and enters the center position inside the air outlet pipe 11.

[0035] Working principle: When in use, first add water to the water collecting cylinder 21, and stop when the water level reaches the lower edge of the annular filter plate 23; then the rotating part of the driving motor 4 drives the water suction cylinder 34 to rotate, and the driving tube 33 is driven by the water suction cylinder 34 to make the water collection cover 31 and the air supply blades 32 rotate inside the air outlet pipe 11; at this time, when the driving tube 33 rotates, it drives the transmission gear 36 to rotate through the gear ring 37, and then the three transmission gears 36 drive the entire suction impeller 35 to rotate through the teeth of the inner ring, and the rotation of the suction impeller 35 sucks the external air from the gap between the air outlet pipe 11 and the air inlet pipe 12 into the water collecting cylinder 21. In this process, the dust in the air is preliminarily removed by the first electrostatic adsorption ring 13 and the second electrostatic adsorption ring 14, and at the same time, the high-speed rotation of the air supply blades 32 sends the air inside the air outlet pipe 11 upward. At this time, due to the lower end of the air outlet pipe 11 and The corresponding position of the upper end of the support seat 22 is blocked by the upper and lower ends of the inner ring of the suction impeller 35, and very little air flows. At the same time, the water inlet at the lower end of the water suction cylinder 34 is filled with water, so that the air on the outside of the annular filter plate 23 will enter its interior, and then complete the secondary filtration of the air to remove dust. The water outlet holes of the air supply blades 32 suck the water inside the dust filter mechanism 2 through the water inlet of the water suction cylinder 34 under high-speed rotation, and are transported by the water suction cylinder 34, the driving pipe 33 and the water collection cover 31 and thrown out from the water outlet holes at the end of the air supply blades 32. The thrown water then hits the inner wall of the air outlet pipe 11 to form droplets. Some of the droplets follow the air and fly into the air, and this part of the air carrying the droplets will combine with the dust in the air without dust reduction, thereby achieving a certain degree of dust reduction effect. Another part of the larger droplets gather on the inner wall of the air outlet pipe 11 and fall back into the dust filter mechanism 2 to be reused next time.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
