Abstract
Description
Technical Field
[0001] This utility model relates to the field of environmental protection equipment technology, and in particular to an integrated dust collection and removal device. Background Technology
[0002] During the construction of new energy photovoltaic projects, dust generated during drilling is difficult to control, leaving operators in a dusty environment and creating poor working conditions. Traditional fog cannons require manual movement alongside the drilling rig, severely impacting drilling efficiency. Fog cannons also require generators to drive the sprayers, and the open-type spraying method results in poor dust removal. Spraying directly onto the drilling hole can lead to difficulties in dust removal, drill bit jamming, and operators being splashed with spray, creating a poor working environment. This also wastes significant transportation costs and spray water resources. Utility Model Content

[0025] like Figure 1 As shown, this embodiment provides an integrated dust collection and removal device, which is installed on the down-the-hole drill rig 2. The integrated dust collection and removal device includes an air compressor 1, a dust collection hood 4, a negative pressure suction pipe 5, a negative pressure ejector 11, and a dust collection and filtration water tank 10.
[0026] The dust collection hood 4 is located above the dust discharge port at the top of the borehole, and the dust collection hood 4 is connected to the negative pressure ejector 11 through the negative pressure suction pipe 5.
[0027] The inlet of the negative pressure ejector 11 is connected to the air compressor 1, and the outlet is below the liquid level in the dust collection and filtration water tank 10.
[0028] The dust collection hood is located above the dust discharge port at the top of the borehole. It is connected to the negative pressure ejector through a negative pressure suction pipe. The negative pressure ejector is connected to the dust collection and filtration water tank. The dust in the air is removed by the action of the water in the dust collection and filtration water tank. The dust collection and filtration water tank is hung on the down-the-hole drill and can be moved synchronously with the drilling operation, so as to achieve the purpose of portable integrated dust collection and removal. It also saves manpower, sprayers and a lot of water resources, and is highly practical.
[0029] A dust collection hood 4 is installed at the bottom of the toothed rail 3 outside the drill rig 2. The dust collection hood 4 collects dust at the dust discharge port at the top of the borehole. The dust collection hood is connected to the negative pressure suction pipe 5, which is connected to the suction chamber 6 of the negative pressure ejector 11.
[0030] The air compressor outlet pipe is connected to a tee, one end of which is connected to a down-the-hole drill and equipped with a second regulating valve 13. The other end is connected to the nozzle pipe of the negative pressure ejector and equipped with a first regulating valve 12 to control dust collection and drilling efficiency.
[0031] The nozzle 7 inlet of the negative pressure ejector 11 is connected to one end of the air duct of the air compressor, and the nozzle outlet is located behind the mixing chamber 8. The negative pressure is generated in the suction chamber by the Venturi tube principle, thereby performing negative pressure dust collection.
[0032] Negative pressure is directed to diffusion chamber 9, and the outlet of diffusion chamber 9 is inserted below the water surface of dust collection and filtration water tank 10 for water filtration and dust removal. Two layers of filter screens 16 are laid on the dust collection water tank to further improve dust removal efficiency.
[0033] The dust collection and filtration water tank 10 is attached to the body of the down-the-hole drill rig 2 and moves synchronously to achieve portable, self-moving dust collection and removal. The attachment design of the dust collection and filtration water tank allows for easy removal and cleaning.
[0034] The negative pressure ejector is fixed on the body of the drilling rig 2 by a bracket and above the dust collection and filtration water tank 10, so as to achieve the purpose of portable and self-moving dust collection and removal.
[0035] To further illustrate the integrated dust collection and removal device described above, this embodiment also provides the working process of the device, as detailed below:
[0036] During the drilling operation, valves 13 and 12 are opened, and high-pressure air is supplied by the air compressor through the air duct 14 for drilling. The high-pressure air enters the nozzle 7 of the negative pressure ejector 11 through the air duct 15, and the high-speed ejected gas forms a negative pressure chamber 6. Dust is drawn into the negative pressure chamber 6 through the dust collection hood 4 and the negative pressure suction pipe 5, and is carried into the mixing chamber 8 by the high-speed air. It is then injected into the dust collection water tank 10 through the diffusion chamber 9, and then passes through two layers of filter screens 16 to form clean air that is discharged into the atmosphere.
[0037] Adjusting valve 12 can control the drilling efficiency, and adjusting valve 13 can control the negative pressure in the negative pressure chamber, thereby controlling the dust collection efficiency.
[0038] Regularly clean the sludge at the bottom of the dust collection and filtration water tank to achieve recycling.
