Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1

[0025] A clog-resistant aeration device, such as Figures 1-5 As shown, it includes an aeration pipe 1, an air inlet pipe 2, and an aeration net 3; the aeration pipe 1 is connected to the air inlet pipe 2 for supplying air into it; the aeration pipe 1 is slidably connected to the aeration net 3 for aerating the sewage.

[0026] Further comprising a circular platform plate one 4 and a circular platform plate two 5; the aeration pipe 1 is fixed with the circular platform plate one 4; the aeration pipe 1 is fixed with the circular platform plate two 5, and the circular platform plate one 4 and the circular platform plate two 5 jointly form a siphon channel; the aeration pipe 1 is provided with four arc-shaped through holes one 101, and all the arc-shaped through holes one 101 are communicated with the siphon channel; further comprising a mounting plate 111, a spring telescopic rod 112, a mounting rod 113, a rotating fan 114, a rotating shaft sleeve 115 and a scraper 116; the aeration net 3 is provided in an inverted conical shape; the aeration pipe 1 is provided with four arc-shaped through holes two 102, which are located above the outer ring side of the aeration net 3; the aeration pipe 1 is fixed with the mounting plate 111; the mounting plate 111 is fixed with the spring telescopic rod 112; the telescopic part of the spring telescopic rod 112 is fixed with the mounting rod 113; the mounting rod 113 is rotatably connected with the rotating shaft sleeve 115, and the rotating shaft sleeve 115 is rotatably connected with the aeration net 3; the rotating shaft sleeve 115 is fixed with the rotating fan 114; the rotating shaft sleeve 115 is fixed with four ring-shaped scrapers 116, and all the scrapers 116 are in contact with the lower surface of the aeration net 3.

[0027] Further comprising a circular platform plate three 6; the aeration pipe 1 is fixed with the circular platform plate three 6 for expanding the bubble flow area.

[0028] The specific work of the above embodiment 1 is as follows: first, install the aeration device on the pipeline of the air conveying equipment in the containing pool, so that the air inlet pipe 2 is communicated with the pipeline of the air conveying equipment, and the circular platform plate two 5 is in contact with the bottom of the containing pool, to complete the installation work.

[0029] During aeration, the air conveying equipment is controlled to convey high-pressure air into the aeration pipe 1 through the air inlet pipe 2, and then the air enters the sewage through the mesh holes of the aeration net 3, and the air entering the sewage becomes dense bubbles, which move from the bottom of the water to the water surface, thereby aerating the sewage.

[0030] It should be noted that when the air flows through the aeration pipe 1, the rapidly flowing air will generate negative pressure in the aeration pipe 1, and the generated negative pressure will in turn draw the sewage at the bottom of the containing pool into the aeration pipe 1 through the siphon channel and the arc-shaped through holes one 101, and the sewage entering the aeration pipe 1 will flow back into the containing pool through the mesh holes of the aeration net 3 under the action of the air, so that the organic pollutants at the bottom of the containing pool can flow back in the containing pool, thereby avoiding the problem that in the prior art, due to the difficulty of the bubbles in pushing the sewage at the bottom of the containing pool to flow, and the organic pollutants in the sewage tend to sink to the bottom of the containing pool, it is difficult to increase the contact opportunity of the organic pollutants at the bottom of the containing pool with the aerobic microorganisms, thereby affecting the overall degradation efficiency.

[0031] The cleaning brushes 117 are also included; the shaft sleeve 115 is fixed with four annularly distributed cleaning brushes 117, and all the cleaning brushes 117 are in contact with the upper surface of the aeration net 3, and the cleaning brushes 117 are arranged in staggered distribution with the scraper 116.

[0032] Each arc-shaped through hole two 102 is provided with an inclined part 10201 for better air passing through the arc-shaped through hole two 102.

[0033] The scraper 116 is arranged in an arc shape.

[0034] The lower surface of the mounting plate 111 is arranged in an arc shape, which is used for making the bubbles impacting the mounting plate 111 flow to both sides to reduce the obstruction of the mounting plate 111 to the bubbles.

[0035] The specific work of the above embodiment 2 is as follows: considering that the suspended solids in the sewage on the bottom of the containing pool will be intercepted by the aeration net 3 when the sewage passes through the aeration net 3, and adheres to the lower surface of the aeration net 3, that is, the mesh of the aeration net 3 will be blocked, thereby causing the aeration net 3 to be unable to normally aerate the sewage.

[0036] Therefore, by setting the aeration net 3 as an inverted cone, opening the arc-shaped through hole one 101 on the aeration pipe 1, and additionally setting the mounting plate 111, the spring telescopic rod 112, the mounting rod 113, the rotating fan 114, the rotating shaft sleeve 115 and the scraper 116, since the air contacts the rotating fan 114, the rotating fan 114 will rotate under the push of the air, and the rotating rotating fan 114 will drive the scraper 116 to rotate through the rotating shaft sleeve 115, so that the rotating scraper 116 scrapes the suspended matter on the lower surface of the aeration net 3, but even if the scraper 116 scrapes the suspended matter on the lower surface of the aeration net 3, the suspended matter is still in the space below the aeration net 3 and will return to the aeration net 3 sooner or later to cause blockage, when the amount of suspended matter entering the aeration pipe 1 increases, the aeration net 3 is seriously blocked, when the total amount of air entering the aeration pipe 1 is greater than the total amount of air passing through the aeration net 3, the air pressure in the aeration pipe 1 will continuously rise, and the aeration net 3 will move upwards in the aeration pipe 1 under the push of the air pressure, and the aeration net 3 moving upwards will push the rotating shaft sleeve 115 and the connected parts to move upwards synchronously, and push the telescopic part of the spring telescopic rod 112 to retract, when the aeration net 3 moves to the position that the outer ring side is above the arc-shaped through hole two 102, in the process that the rotating scraper 116 scrapes the suspended matter on the lower surface of the aeration net 3, since the aeration net 3 is set as an inverted cone and the outer ring side of the aeration net 3 is above the arc-shaped through hole two 102, when the air contacts the aeration net 3, the air is blocked by the aeration net 3 and flows along the lower surface of the aeration net 3, and then flows out of the aeration pipe 1 through the arc-shaped through hole two 102, and when the air flows along the lower surface of the aeration net 3, the air will drive the suspended matter scraped by the scraper 116 to move towards the arc-shaped through hole two 102, and finally the suspended matter will flow out of the aeration pipe 1 through the arc-shaped through hole two 102, so that the aeration net 3 can be self-cleaned according to the blockage condition to prevent the suspended matter from being intercepted by the aeration net 3 when the sewage at the bottom of the containing pool passes through the aeration net 3 and adhering to the lower surface of the aeration net 3, that is, the mesh holes of the aeration net 3 are blocked, thereby causing the problem that the aeration net 3 cannot normally aerate the sewage.

[0037] Further, in addition to the rotating fan 114 driving the scraper 116 to rotate through the rotating shaft sleeve 115, the rotating fan 114 will also drive the cleaning brush 117 to rotate, and the rotating cleaning brush 117 will push the suspended matter blocked in the mesh holes of the aeration net 3 to separate the suspended matter from the aeration net 3, so as to dredge the mesh holes of the aeration net 3 to avoid the problem that the mesh holes of the aeration net 3 are blocked by the suspended matter.

[0038] When the aeration net 3 is dredged, the telescopic part of the spring telescopic rod 112 will push the mounting rod 113 and the connected parts to move downwards to the initial position, so that the outer ring side of the aeration net 3 is located below the arc-shaped through hole two 102 again, that is, the aeration net 3 continues to aerate the sewage.

[0039] Example 2

[0040] On the basis of embodiment 1, as shown in Figures 1-3 The air aeration pipe 1 is internally fixed with a pressure relief disc 211 for reducing the impact force of the air aeration net 3, and the pressure relief disc 211 is located below the arc-shaped through hole one 101.

[0041] The pressure relief disc 211 is arranged in a structure with a low middle and high periphery, which is used for air shunting, so that the pressure relief disc 211 can better relieve the air pressure.

[0042] The air aeration pipe 1 is composed of a cylindrical part 103 and a circular tube part 104, and the cylindrical part 103 and the circular tube part 104 are detachably connected.

[0043] The specific work of the above embodiment 2 is as follows: considering that when the air enters the air aeration pipe 1 through the air inlet pipe 2, the air will concentrate and rush to the air aeration net 3, and the air aeration net 3 will be subjected to strong impact force, and under this impact force, the air aeration net 3 is easy to appear the case that the air aeration net 3 is not blocked, and the outer ring side is also located above the arc-shaped through hole two 102, which further leads to the case that the air aeration net 3 cannot normally aerate the sewage.

[0044] Therefore, the pressure relief disc 211 is added, so that when the air flows into the air aeration pipe 1, since the entire air aeration pipe 1 is in the sewage, that is, there is sewage in the entire air aeration pipe 1, when the air passes through the pressure relief disc 211, the air will form bubbles under the action of the pressure relief disc 211, and when the bubbles pass through the air aeration net 3, the bubbles will be cut by the mesh holes of the air aeration net 3 to form smaller bubbles, and since the air has formed bubbles when passing through the air aeration net 3, it will not push the air aeration net 3 to move upward, that is, it can play a role in relieving the air pressure, so as to avoid the problem that the air aeration net 3 will be subjected to strong impact force under the impact of the air concentration, and the air aeration net 3 is easy to appear the case that the air aeration net 3 is not blocked, and the outer ring side is also located above the arc-shaped through hole two 102.

[0045] It should be noted that by setting the aeration pipe 1 to be composed of the cylindrical part 103 and the circular pipe part 104, and the cylindrical part 103 and the circular pipe part 104 are detachably connected, when the aeration net 3 is seriously blocked after long time aeration of sewage, that is, the aeration net 3 cannot be dredged by the scraper 116 and the cleaning brush 117, the circular pipe part 104 can be manually detached from the cylindrical part 103, and then the circular pipe part 104 and the connected parts are taken out of the containing pool, so as to facilitate replacement of the aeration net 3. At the same time, after the circular pipe part 104 is detached from the cylindrical part 103, the air inlet pipe 2, the cylindrical part 103 and the pressure relief disc 211 will form a simple aeration structure, so that during replacement of the aeration net 3, the simple aeration structure composed of the air inlet pipe 2, the cylindrical part 103 and the pressure relief disc 211 can continue to aerate the sewage. It should be noted that the simple aeration structure does not have the function of pumping the sewage at the bottom of the containing pool.

Therefore, the scope of the disclosure should not be limited to the above-described embodiments, but should be determined only by the appended claims, and defined by equivalents thereof.
