[0014] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0015] Refer to the drawings Figs. 1-3The utility model provides a kind of stepped multi-airway aeration device, including helical stepped aeration pipe 1, helical stepped aeration pipe 1 is helical square tube, partition plate 5 is equipped in helical stepped aeration pipe 1, and the outside flow passage 6 and inner flow passage 7 are formed in the two sides of partition plate 5, so that two airways are formed, the setting of multi-airway is realized, and the aeration assembly 8 on the outer wall of helical stepped aeration pipe 1 is equipped in the outside flow passage 6 and inner flow passage 7, and the aeration assembly 8 includes the intercepting baffle 81 fixed on helical stepped aeration pipe 1, and also includes aeration hole 82 opened on helical stepped aeration pipe 1, by this setting, helical square tube forms helical stepped aeration pipe 1, so that helical stepped aeration pipe 1 forms the step type rising constantly, so that helical stepped aeration pipe 1 can be extended from the bottom to the top of aeration tank with large contact area, so that the range of aeration is larger, and the setting of this helical stepped type makes the pressure of gas in helical stepped aeration pipe 1 increase, so as to change the flow mode of traditional gas flow, increase the pressure in aeration pipe, make aeration more smooth, not easy to block aeration hole, and make gas flow high-speed injection, realize the promotion of aeration, and make one-time aeration from bottom to top, and the aeration range formed is helical rising, so that aeration area is improved.

[0016] It needs to be explained that the aeration assembly 8 arranged in the outside flow passage 6 and inner flow passage 7 is equidistant distribution, and the interval between adjacent aeration assembly 8 in the outside flow passage 6 is greater than the interval between adjacent aeration assembly 8 in the inner flow passage 7, and the included angle between intercepting baffle 81 in the outside flow passage 6 and the outer wall of helical stepped aeration pipe 1 is greater than the included angle between intercepting baffle 81 in the inner flow passage 7 and the outer wall of helical stepped aeration pipe 1, because the outside flow passage 6 is located on the outside of helical stepped aeration pipe 1, so as to have larger contact area with sewage, so that the interval between adjacent aeration assembly 8 increases, so that the amount of aeration from this place also increases, on the contrary, the inside of helical stepped aeration pipe 1 has small contact area with sewage, so that the amount of aeration needed is relatively small, so that the setting makes the aeration state more reasonable.

[0017] It needs to be explained that, in the embodiment, the included angle between the intercepting baffle 81 in the outer flow passage 6 and the spiral stepped aeration pipe 1 is 17 degrees, and the included angle between the intercepting baffle 81 in the inner flow passage 7 and the spiral stepped aeration pipe 1 is 15 degrees. Specifically, according to the existing use data test, under the condition that the cross-sectional area of the constant spiral stepped aeration pipe 1 is 100 cm2, the length is 2 m, the spacing between the intercepting baffles 81 in the outer flow passage 6 is 10 cm, the spacing between the intercepting baffles 81 in the inner flow passage 7 is 5 cm, and the air intake of the Nanjing Kaipude Pump Co., Ltd. submersible oxygenation aerator QXB7.5 is 100 M3 / h, then it is measured that the aeration at the aeration hole 82 in the outer flow passage 6 is about twice the aeration amount at the aeration hole 82 in the inner flow passage 7.

[0018] It also needs to be explained that the base 3 is fixedly installed with the gas conveying pipe 2, and the gas conveying pipe 2 is fixedly connected and communicated with the bottom air inlet of the spiral stepped aeration pipe 1.

[0019] Specifically, in operation, the gas conveying pipe 2 is connected with the output pipe of the external aeration pump, and when the aeration pump is started, the gas can be input into the spiral stepped aeration pipe 1 through the gas conveying pipe 2. The partition plate 5 in the spiral stepped aeration pipe 1 separates the gas, so that the gas uniformly enters the outer flow passage 6 and the inner flow passage 7, and then when moving in the outer flow passage 6 and the inner flow passage 7, the gas will pass through the intercepting part of the intercepting baffle 81 and be intercepted by the intercepting baffle 81, so as to be discharged from the aeration hole 82, thereby realizing aeration.
