Description

Technical Field

[0001] The utility model relates to the technical field of aeration equipment, in particular to aeration equipment for treating domestic sewage. Background Art

[0002] Aeration equipment is used when treating domestic sewage. Aeration refers to the artificial introduction of air into the biochemical aeration tank through appropriate equipment to achieve the desired purpose. Aeration not only allows the liquid in the tank to come into contact with air for oxygenation, but also accelerates the transfer of oxygen in the air to the liquid due to the stirring of the liquid, thereby completing the purpose of oxygenation. In addition, aeration also prevents the suspended matter in the tank from sinking and strengthens the contact between organic matter, microorganisms and dissolved oxygen in the tank, thereby ensuring that the microorganisms in the tank can oxidize and decompose organic matter in the sewage under the condition of sufficient dissolved oxygen.

[0003] In order to improve the aeration effect when treating sewage, the prior art has made many improvements to domestic sewage treatment aeration equipment. For example, patent publication number CN220520273U discloses a domestic sewage treatment aeration equipment for a power plant, including an aeration block, wherein the interior of the aeration block is fixedly connected to a fixed mounting pipe, the interior of the fixed mounting pipe is fixedly connected to a gas transmission pipe, the outer surface of the fixed mounting pipe is movably sleeved with a movable cleaning mechanism, the outer surface of the movable cleaning mechanism is movably connected to a power output mechanism, one end side of the power output mechanism is fixedly connected to a first support column, and the bottom end of the first support column is fixedly connected to a first mounting base plate; the utility model is provided with a movable cleaning mechanism and a power output mechanism, so that the movable cleaning mechanism and the power output mechanism can cooperate with each other to stably clean the outer surface of the top surface of the aeration block before use, thereby preventing excessive accumulation of impurities from causing blockage, so that the gas cannot be quickly discharged to the outside to form aeration, and the overall structure is simple and easy and quick to use.

[0004] The above patents have obvious beneficial effects, but still have the following deficiencies in actual operation:

[0005] In the above-mentioned comparative document, the upper side of the aeration block is cleaned by rotating the connected cleaning block to prevent excessive accumulation of impurities on the upper side of the aeration block and causing blockage. However, in reality, as in the above-mentioned comparative document, a number of aeration holes are opened on the upper side of the aeration block, and air is ejected through the aeration holes. The aeration tank contains a large number of microorganisms. When the aeration block is not working, a large amount of microbial impurities will enter the aeration holes on the aeration block, and the aeration holes will be blocked. The connected cleaning block in the above-mentioned comparative document can only clean the upper side of the aeration block, and the microbial impurities in the aeration holes cannot be cleaned. The next time the aeration equipment needs to be turned on, the air will not be able to pass through the aeration holes normally, resulting in a reduction in the aeration effect during sewage treatment. Therefore, there is an urgent need in this field to improve the aeration equipment for domestic sewage treatment to solve the defects of the existing technology. Summary of the Invention

[0006] In view of the deficiencies of the prior art, the present utility model provides an aeration device for domestic sewage treatment. In the present utility model, it is possible to prevent the aeration holes on the aeration device from being blocked, and improve the aeration effect during domestic sewage treatment.

[0007] To achieve the above object, the present utility model provides the following technical solution: An aeration device for domestic sewage treatment, including a main air delivery pipe.

[0029] Example 1

[0030] See also Figure 1-Figure 7 , the domestic sewage treatment aeration equipment includes a main air pipe 1, a plurality of branch air pipes 2 connected to the main air pipe 1 are fixedly installed on the lower side of the main air pipe 1, and also includes a plurality of aeration plates 3 arranged below the branch air pipes 2, and a cover plate 4 adapted to the aeration plate 3 is threadedly connected on the aeration plate 3. The lower end of the branch air pipe 2 is fixedly mounted on the upper surface of the cover plate 4 and is connected to the inside of the aeration plate 3. A plurality of aeration holes 5 are opened on the cover plate 4. A movable plate 6 adapted to its internal cavity is provided in the aeration plate 3. A plurality of sealing plugs 7 adapted to the aeration holes 5 are fixedly connected to the upper surface of the movable plate 6. An elastic plug 7 is fixedly connected between the lower surface of the movable plate 6 and the bottom of the aeration plate 3. Spring 8, an extrusion plate 9 is provided on the side of the branch gas pipe 2, one end of which passes through the cover plate 4 and abuts against the upper surface of the movable plate 6. A support rod 10 is provided on the upper side of the main gas pipe 1 for support. The support rod 10 is provided with a driving unit 11 for moving the plurality of extrusion plates 9 downward. The driving unit 11 includes a telescopic device 15 fixedly mounted on the upper side of the support rod 10. The upper side of the support rod 10 is slidably connected to a moving rod 12 with one end fixedly connected to the telescopic end of the telescopic device 15. Several push rods 13 are fixedly connected to the side of the moving rod 12. Each extrusion plate 9 is provided with an extrusion groove 14 adapted to the push rod 13 on the upper side, and the extrusion groove 14 is inclined.

[0031] Specific implementation method in this embodiment: Install the support rod 10 above the aeration tank. The main air delivery pipe 1 is fixedly installed on the lower side of the support rod 10. A plurality of branch air delivery pipes 2 are fixedly installed on the lower side of the main air delivery pipe 1. The cover plate 4 is fixedly installed at the lower end of the branch air delivery pipe 2. The aeration disc 3 is connected to the lower part of the cover plate 4 by means of threaded connection. Domestic sewage is discharged into the aeration tank after a series of filtration treatments. When it is necessary to aerate the sewage in the aeration tank, air is conveyed through the main air delivery pipe 1. The air enters the branch air delivery pipes 2. By starting the telescopic device 15, the telescopic end of the telescopic device 15 drives the moving rod 12 to move on the support rod 10. When the moving rod 12 moves, it drives the push rod 13 to translate. One end of the push rod 13 is slidably connected in the extrusion groove 14. The extrusion groove 14 is inclined. Therefore, when the push rod 13 translates, it will push the extrusion plate 9 to move downward by squeezing the side wall of the extrusion groove 14. When the extrusion plate 9 moves downward, its end squeezes the moving plate 6 to move downward in the aeration disc 3. The sealing plug 7 also moves downward to disengage from the air hole 5. At this time, the spring 8 is compressed, and the air is discharged from the air hole 5 to aerate the domestic sewage in the aeration tank. When it is not necessary to aerate the sewage, by reversely controlling the movement of the telescopic end of the telescopic device 15, the push rod 13 drives the extrusion plate 9 to move upward through the extrusion groove 14. The tension of the spring 8 is released and pushes the moving plate 6 to move upward. The sealing plug 7 is inserted into the air hole 5. The sealing plug 7 is elastic, and the sealing plug 7 seals the air hole 5, so as to prevent the air holes 5 on the aeration equipment from being blocked and improve the aeration effect during the treatment of domestic sewage.

[0032] Among them, the telescopic device 15 mentioned above can be purchased in the market. It belongs to mature technology and has been fully disclosed. Therefore, it will not be repeated in the specification. The telescopic device 15 is equipped with a power connection line, and it is electrically connected to the external main controller and 220V phase voltage (or connected to an external hydraulic station through a pipeline) through the power cord. And the main controller can be a conventional known device such as a computer that plays a control role.
