[0027] Embodiment one:

[0028] Please refer to Figures 1-5The application provides a guiding drainage type air separation device, which comprises a bottom plate 1, a gas collecting tank 2 and a water storage tank 14 are arranged on the bottom plate 1, and a stirring and scraping mechanism is arranged in the gas collecting tank 2; the stirring and scraping mechanism comprises a driving shaft 6 capable of rotating in the gas collecting tank 2, a second supporting plate 8 is arranged in the gas collecting tank 2, the driving shaft 6 is rotationally connected to the second supporting plate 8, so that the driving shaft 6 is supported, stirring blades 7 capable of dispersing gas are arranged on the driving shaft 6, scrapers 9 are arranged on the driving shaft 6 through connecting frames 10, a plurality of scrapers 9 are arranged, and the plurality of scrapers 9 are arranged in an inclined manner, so that impurity particles falling to the bottom of the gas collecting tank 2 are swept into the inside of a sewage outlet 13 arranged on the gas collecting tank 2, and a screw blade 11 is arranged at the lower end of the driving shaft 6, so that impurities are prevented from being blocked in the inside of the sewage outlet 13.

[0029] In this embodiment, the bottom of the gas collecting tank 2 is in a slope structure, and the scrapers 9 are arranged in close contact with the bottom wall of the gas collecting tank 2, so that impurities can flow into the inside of the sewage outlet 13 along the slope, and the problem that impurities are accumulated in the inside of the gas collecting tank 2 and are not easy to clean is avoided.

[0030] In this embodiment, a first supporting plate 3 is arranged in the inside of the gas collecting tank 2 and serves as a support, a sealing shell 5 is arranged on the first supporting plate 3, an alternating current motor 4 for driving the driving shaft 6 to rotate is arranged in the inside of the sealing shell 5, and the sealing shell 5 is arranged in close contact with the first supporting plate 3, so that the alternating current motor 4 is not affected by the spraying water and is prevented from being short-circuited.

[0031] In this embodiment, an air inlet pipe 27 is arranged on the gas collecting tank 2 and is used for filling gas, and the height of the stirring blades 7 is higher than the height of the air inlet pipe 27, so that the gas floating above the air inlet pipe 27 can be dispersed.

[0032] In this embodiment, an air outlet pipe 28 is arranged at the top of the gas collecting tank 2, an electric fan 29 is arranged in the inside of the air outlet pipe 28 and is used for extracting pure gas, so as to play a guiding and draining role, so that the gas always floats upward, and a gas detection unit same as that disclosed in CN212818849U can be arranged in the inside of the air outlet pipe 28 and is used for detecting whether the gas meets the impurity removal standard, the gas collecting tank 2 is connected with the water storage tank 14 through a drain pipe 15, a water pump 24 for spraying water in the inside of the water storage tank 14 is arranged on the water storage tank 14, the water pump 24 is connected with a spraying head 26 through a first conduit 23 and a second conduit 25, and is used for spraying gas to remove impurities, the second conduit 25 and the spraying head 26 are arranged in the inside of the gas collecting tank 2 and are located above the stirring blades 7.

[0033] Specifically, by pouring gas from the gas inlet pipe 27, and opening the electric fan 29 to make the gas flow upwards, before this, the alternating current motor 4 can be opened to drive the rotating drive shaft 6 to drive the stirring blade 7 to rotate, and the gas is dispersed and filled in the inside of the gas collecting box 2 by the rotation of the stirring blade 7, so that it is more comprehensive by the spraying of the spraying head 26, and the impurity removal efficiency is high.

And the lower part of the drive shaft 6 is provided with the auger blade 11 rotating in the inside of the sewage outlet 13, which can transport the impurity particles out to avoid excessive accumulation to cause the sewage outlet 13 to be blocked, which brings inconvenience to the gas air separation and impurity removal.

[0034] Example two:

[0035] On the basis of example one, the water storage tank 14 is provided with an adsorption mechanism; the adsorption mechanism includes a disc 18 rotatingly arranged in the inside of the water storage tank 14, a servo motor 17 is arranged on the water storage tank 14 for driving the disc 18 to rotate, and is located outside the water storage tank 14. A plurality of placement grooves arranged in a ring array are arranged on the disc 18, and an installation cylinder 19 is arranged in each placement groove. A fixing bolt 20 is arranged on the disc 18 for fixing the installation cylinder 19, specifically, the fixing bolt 20 and the disc 18 are screw-connected, and the bottom of the fixing bolt 20 abuts against the outer wall of the installation cylinder 19 to fix the installation cylinder 19.

[0038] Specifically, by aligning one of the installation cylinders 19 opposite the drain pipe 15 and abutting the installation cylinder 19 with the drain pipe 15, the spray water with impurity particles must pass through the adsorbing cotton 21 inside the installation cylinder 19 and the filter screen 22 at the end of the installation cylinder 19 to re-enter the inside of the water storage tank 14 for recycling. When the adsorbing cotton 21 is saturated, the servo motor 17 can drive the disc 18 to rotate, and then the disc 18 drives the other installation cylinder 19 to align with the drain pipe 15 to continuously filter and adsorb. Through this way, the adsorbed impurities can be intercepted inside the installation cylinder 19 by the adsorbing cotton 21 and the filter screen 22 and cannot enter the inside of the water storage tank 14, so as to avoid the problem that the inside of the water storage tank 14 needs to be manually cleaned of impurity particles after the impurities are removed.
