Description

Technical Field

[0001] This utility model relates to the technical field of environmental dust removal devices for power engineering construction, and specifically to an environmental dust removal device for power engineering construction. Background Technology

[0002] In existing technologies, most power engineering construction projects use a single filter screen for filtration. However, the filter screen has limited effectiveness in treating dust particles of different sizes. For fine dust, a single filtration method is insufficient to ensure sufficient settling, resulting in the exhaust air still containing a significant amount of dust. This fails to effectively reduce dust pollution in the construction area, thereby threatening the health of construction workers and the surrounding environment. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] like Figure 1-5 As shown, this utility model provides an environmentally friendly dust removal device for power engineering construction, including a dust collection box 1. Casters 2 are rotatably mounted on all four sides of the bottom of the dust collection box 1. A suction port 3 is fixedly installed on the right side of the dust collection box 1. An air outlet 4 is fixedly installed on the top of the dust collection box 1. A drying plate 41 is fixedly installed on the inner wall of the air outlet 4. A push handle 5 is fixedly installed at the rear top of the dust collection box 1. An intercepting net 31 is fixedly installed inside the suction port 3. A fixed... A servo motor 32 is installed, and a helical gear 33 is fixedly installed on the output end of the servo motor 32. A helical gear 34 is meshed on one side of the helical gear 33. Dust covers are fitted on the outer surfaces of the helical gear 33 and the helical gear 34. A drive rod 35 is fixedly installed on the output end of the helical gear 34. A vacuum fan 36 is fixedly fitted on the outer surface of the drive rod 35. A dust scraper 37 is fixedly fitted on the other end of the drive rod 35. The dust scraper 37 is attached to the outer surface of the interception net 31.

[0025] Furthermore, after the servo motor 32 starts, its output end drives the helical gear 33 to rotate. Since the helical gear 33 meshes with the helical gear 34, the power is transmitted to the helical gear 34 and drives the drive rod 35 to rotate. The drive rod 35 synchronously drives the dust suction fan 36 on the outer surface to rotate. The rotation of the dust suction fan generates negative pressure suction, which draws the dusty air in the construction area into the dust collection box 1 from the dust suction port 3. At this time, the interception net 31 inside the dust suction port 3 will first perform preliminary filtration of large particulate impurities in the air. At the same time, the dust scraper 37 at the other end of the drive rod 35 rotates synchronously and adheres to the outer surface of the interception net 31, which can clean the impurities attached to the surface of the interception net 31 in real time.

[0026] Example 2

[0027] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a gathering cover 11 is fixedly installed on the inner wall of the dust collection box 1, a spray plate 2 12 is fixedly installed at the upper through hole of the gathering cover 11, a filter screen plate 13 is movably inserted into the lower part of the gathering cover 11, a circulation pump 14 is fixedly installed on the left side shell of the dust collection box 1, a suction pipe 15 is fixedly connected to the suction end of the circulation pump 14, the other end of the suction pipe 15 extends into the left side shell of the dust collection box 1, a discharge pipe 16 is fixedly installed at the discharge end of the circulation pump 14, the other end of the discharge pipe 16 penetrates the left side shell of the dust collection box 1 and extends into the left side interior of the spray plate 2 12.

[0028] Furthermore, during the dust collection process, the circulation pump 14 starts simultaneously, drawing the dust removal liquid stored at the bottom of the dust collection box 1 through the liquid extraction pipe 15. The drawn dust removal liquid is transported through the drain pipe 16 and directly enters the spray plate 12. After the gas enters the dust collection box 1, it gathers towards the center under the guidance of the gathering hood 11. At this time, the spray plate 12 above the gathering hood 11 sprays out a large amount of mist-like dust removal liquid to spray and remove dust from the air. Fine dust and liquid are fully mixed and fall to the bottom of the gathering hood 11 under the action of gravity. After being filtered by the filter screen 13, the liquid permeates to the bottom of the dust collection box 1 and re-enters the circulation, while the filtered dust impurities are trapped on the filter screen 13.

[0029] Example 3

[0030] like Figure 1-5 As shown, based on embodiments 1-2, this utility model provides a technical solution: preferably, a water guide channel is fixedly installed on the bottom end of the interception net 31 on the bottom end shell of the dust suction port 3, and the other end of the water guide channel extends into the right side of the dust collection box 1. A diversion pipe 17 is fixedly installed inside the rear side of the drain pipe 16, and the other end of the diversion pipe 17 extends into the top end of the dust suction port 3 and is fixedly installed with a spray plate 38. The spray plate 38 is fixedly installed inside the dust suction port 3 at the right side of the interception net 31.

[0031] Furthermore, the liquid is transported and sprayed onto the outer surface of the interceptor net 31 through the diversion pipe 17 behind the drain pipe 16 to flush the interceptor net 31. The flushed liquid will flow into the dust collection box 1 through the water guide channel at the bottom of the dust suction port 3 to achieve liquid recovery.

[0032] The solution uses a PLC as the core control component. The PLC establishes a connection with the servo motor 32 and the circulating pump 14 through RS-485 communication. When it is necessary to start the servo motor 32 and the circulating pump 14, the PLC sends a start command to the servo motor 32 and the circulating pump 14 to start them.

[0033] The working principle of the environmental dust removal device used in the construction of this power project will be explained in detail below.

[0034] like Figure 1-5 As shown, during use, the operator moves the device to the dusty area of ​​the power engineering construction site by pushing the handle 5 in conjunction with the moving wheels 2. After the servo motor 32 starts, its output end drives the helical gear 1 33 to rotate. Since the helical gear 1 33 meshes with the helical gear 2 34, the power is transmitted to the helical gear 2 34 and drives the drive rod 35 to rotate. The drive rod 35 synchronously drives the dust suction fan 36 on the outer surface to rotate. The rotation of the dust suction fan 36 generates negative pressure suction, which draws the dusty air in the construction area into the dust collection box 1 from the dust suction port 3. At this time, the intercepting net 31 inside the dust suction port 3 will first perform preliminary filtration of large particles of impurities in the air. At the same time, the dust scraper 37 at the other end of the drive rod 35 rotates synchronously and adheres to the outer surface of the intercepting net 31, which can clean the impurities attached to the surface of the intercepting net 31 in real time. During the dust collection process, the circulation pump 14 starts synchronously, and the dust collection fan 37 rotates synchronously with the drive rod 35 to clean the dust collection box 1. The liquid pipe 15 draws out the dust removal liquid stored at the bottom of the dust collection box 1. The drawn dust removal liquid is transported through the drain pipe 16. Part of it enters the spray plate 12 directly through the drain pipe 16, while the other part is transported through the diversion pipe 17 behind the drain pipe 16 and sprayed onto the outer surface of the interception net 31 to flush the interception net 31. The flushing liquid flows into the dust collection box 1 through the water guide channel at the bottom of the suction port 3 to achieve liquid recovery. After the gas enters the dust collection box 1, it gathers towards the center under the guidance of the gathering hood 11. At this time, the spray plate 12 above the gathering hood 11 sprays out a large amount of mist-like dust removal liquid to spray and remove dust from the air. Fine dust and liquid are fully mixed and fall to the bottom of the gathering hood 11 under the action of gravity. After being filtered by the filter screen 13, the liquid permeates to the bottom of the dust collection box 1 to re-enter the circulation, while the filtered dust impurities are trapped on the filter screen 13.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
