Description

Technical Field

[0001] The utility model belongs to the technical field of carbonization tank aeration equipment, and in particular relates to an aeration device for a sewage treatment carbonization tank. Background Art

[0002] Aeration refers to the process of forcing oxygen in the air to transfer into the liquid. Its purpose is to obtain sufficient dissolved oxygen. In addition, aeration also prevents the suspended matter in the pool from sinking and strengthens the contact between the organic matter in the pool and the microorganisms and dissolved oxygen, thereby ensuring that the microorganisms in the pool can oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen. Aeration is an important method of sewage treatment.

[0003] At present, a Chinese patent with a publication (announcement) number of CN211141672U discloses an aeration device for sewage treatment, including a bracket and an outer ring stirring frame, buoys are fixedly welded at the bottom of both ends of the bracket, a fixed block is fixedly welded on the outside of the bracket, a driving machine is fixedly connected to the top of the fixed block, a rotating shaft is rotatably connected to the bottom of the driving machine, an aeration pipe is fixedly connected to the bottom of the bracket, a main connecting pipe is fixedly connected to the outer end of the aeration pipe, a plurality of groups of suction pipes are fixedly connected to the bottom of the main connecting pipe, an aeration head is fixedly connected to the outside of the suction pipe, an aeration box is provided at the bottom of the aeration pipe, and the aeration pipe is connected in series with the aeration box, a rotating pillar is fixedly connected to the bottom of the fixed block, a bearing is provided on the outside of the rotating pillar, an inner ring stirring blade is welded to the outside of the bearing, and an outer ring stirring blade interlaced with the inner ring stirring blade is provided on the inner side of the outer ring stirring frame.

[0004] Although the above-mentioned aeration device for sewage treatment uses a stirring device to stir the bottom sewage and discharge gas into the sewage to make the sewage and bubbles mix more evenly and further improve the aeration efficiency, the above-mentioned device only uses an aeration head, an aeration pipe and an aeration box to cooperate with each other, so that the aeration efficiency still has a lot of room for improvement.

[0026] See attached Figure 1-4 As shown, the aeration device for a sewage treatment carbonization tank of an embodiment of the utility model comprises a floating frame 1 placed in the sewage treatment carbonization tank, and an aeration treatment component 4 for the sewage treatment carbonization tank. A No. 1 motor 2 is arranged at one end of the inner center of the upper surface of the floating frame 1, and a bottom plate 5 is arranged at the lower end of the No. 1 motor 2. The aeration treatment component 4 for the sewage treatment carbonization tank is arranged at both ends of the upper surface of the floating frame 1, and an inflatable bag 6 is fixedly installed at the four corners of the lower surface of the floating frame 1.

[0027] The floating frame 1 is connected by horizontal plates in the middle, and the floating frame 1 is in an I-shape as a whole.

[0028] A connection plate 3 is detachably connected to one end of the upper surface of the floating frame 1 , and a blower 7 is provided at one end of the upper surface of the connection plate 3 .

The floating frame 1 is in an I-shape, and an inflatable bag 6 is arranged at the bottom to effectively increase the buoyancy, so that the aeration device for a sewage treatment carbonization tank can work stably on the water surface. At the same time, the blower 7 arranged on the upper surface of the connecting plate 3 can effectively blow air into the aeration pipe 9 for use, which can further improve the aeration efficiency.

[0030] The pipes connected in the aeration treatment assembly 4 of the sewage treatment carbonization tank can be repositioned as required without affecting the practicality of the aeration device of the sewage treatment carbonization tank.
