Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater aeration device. Background Technology

[0002] Aeration devices are core equipment in wastewater treatment, primarily used to oxygenate sewage, promote the degradation of organic matter by aerobic microorganisms, and simultaneously agitate the water to prevent sludge sedimentation. Their core function is to improve oxygen transfer efficiency, ensuring efficient biochemical reactions. The selection of an aeration device requires comprehensive consideration of water quality, treatment scale, energy consumption, and maintenance costs. High-efficiency aeration technologies (such as micro-nano bubbles and intelligent aeration control) are becoming a development trend to reduce energy consumption and improve treatment efficiency. This equipment is widely used in municipal wastewater, industrial wastewater, and aquaculture, and is a key component of processes such as activated sludge and biofilm processes.

[0003] Current aeration devices mainly consist of a main air inlet pipe fixed to the bottom of the aeration tank and an aeration disc installed on the main air inlet pipe. However, after prolonged use, the aeration holes at the top of the aeration discs become clogged. At this point, aeration needs to be stopped, and the aeration device needs to be manually disassembled to replace or clean the sludge inside the aeration holes. This type of aeration device that requires frequent manual cleaning is not convenient to use. In addition, the air bubbles generated by aeration are only located near the aeration head, which prevents oxygen from fully contacting the water, resulting in poor aeration effect. Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wastewater aeration device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sewage aeration device, including a main air inlet pipe, a plurality of aeration components are installed at equal intervals on the surface of the main air inlet pipe, and the aeration components include aeration heads, a vertical pipe is fixed through and fixed to the bottom wall of the aeration head, the bottom end of the vertical pipe is connected to the main air inlet pipe, a plurality of aeration holes are opened on the top wall of the aeration head, a blockage clearing component is arranged above the aeration head, a cutting component is passed through the middle of the blockage clearing component and the aeration head, and a driving component for pushing the blockage clearing component to move is arranged both inside and outside the aeration head.

[0006] Furthermore, the bottom surface of the vertical pipe is provided with threads, and the surface of the main air intake pipe is fixed with multiple internal threaded connectors for screwing into the vertical pipe.

[0007] Furthermore, the unclogging component includes a frame plate located above the aeration head, a metal mesh fixed inside the frame plate, and needles fixed on the lower surface of the metal mesh and directly above each aeration hole.

[0008] Furthermore, the drive assembly includes a support plate and a slip ring that are slidably sleeved on the surface of the vertical pipe. The slip ring is located inside the aeration head, and the support plate is located outside the aeration head. A connecting rod is fixed between the support plate and the slip ring. A through hole for the connecting rod to pass through is opened on the bottom wall of the aeration head. Support rods are fixed on both sides of the upper surface of the support plate, and the top of the support rods is fixedly connected to the frame plate.

[0009] Furthermore, both the inner and outer walls of the slip ring are fixed with sealing rings.

[0010] Furthermore, a spring is fixed together on the lower surface of the slip ring and the inner bottom wall of the aeration head.

[0011] Furthermore, the cutting assembly includes a vertical shaft that penetrates the top wall of the aeration head. The vertical shaft is rotatably connected to the top wall of the aeration head via a sealed bearing. A circular hole is provided in the middle of the frame plate. The top end of the vertical shaft passes through the circular hole and is fixed with a cutting blade. The bottom end of the vertical shaft is located inside the vertical tube and is fixed with an impeller.

[0012] The beneficial effects of this utility model are:

[0013] 1. In use, this utility model is a sewage aeration device, which is equipped with a main air inlet pipe, an aeration head, a vertical pipe, a blockage clearing component, and a drive component. When the aeration hole at the top of the aeration head is blocked, the oxygen entering the aeration head from the vertical pipe cannot be discharged, and the air pressure inside the aeration head increases, thereby pushing the slip ring of the drive component to move down. Then, the support rod drives the blockage clearing component to descend, and the needle of the blockage clearing component is inserted into the aeration hole to clean the aeration hole. After the aeration hole resumes air discharge, the spring pushes the slip ring to reset, and the needle withdraws from the aeration hole, thereby realizing the automatic blockage clearing function without the need for frequent manual cleaning.

[0014] 2. When in use, this utility model is a sewage aeration device with a cutting component. When oxygen enters from the vertical pipe, it will drive the impeller to rotate, thereby driving the vertical shaft and the cutting blade to rotate. The cutting blade cuts the bubbles into smaller pieces, which is conducive to the dispersion of bubbles and full contact with the water, thus improving the aeration effect.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-3 As shown, a wastewater aeration device is disclosed, comprising a main air inlet pipe 1, with multiple aeration components evenly installed on the surface of the main air inlet pipe 1, and each aeration component including an aeration head 3. A vertical pipe 4 is inserted through and fixed to the bottom wall of the aeration head 3, and the bottom end of the vertical pipe 4 is connected to the main air inlet pipe 1. Several aeration holes 32 are opened on the top wall of the aeration head 3. A cleaning component 5 is arranged above the aeration head 3. A cutting component 6 is inserted through the middle of the cleaning component 5 and the aeration head 3. A driving component 7 for moving the cleaning component 5 is arranged both inside and outside the aeration head 3.

[0023] The bottom surface of the vertical pipe 4 is threaded, and the surface of the main air intake pipe 1 is fixed with multiple internal threaded connectors 2 for screwing into the vertical pipe 4.

[0024] In this embodiment, the main air inlet pipe 1 is connected to the air supply equipment. Oxygen enters each aeration head 3 from the main air inlet pipe 1 and is then discharged from the aeration hole 32 to achieve aeration operation.

[0025] The unclogging component 5 includes a frame plate 51 located above the aeration head 3. A metal mesh 52 is fixed inside the frame plate 51. A needle 53 is fixed on the lower surface of the metal mesh 52 and directly above each aeration hole 32.

[0026] In this embodiment, the diameter of the needle 53 is smaller than that of the aeration hole 32. By inserting the needle 53 into the aeration hole 32, the sludge inside the aeration hole 32 can be cleaned, allowing the aeration hole 32 to resume aeration. Furthermore, to prevent the aeration hole 32 from being blocked when the needle 53 cleans it, air holes can be opened on the side wall of the needle 53. When the needle 53 is inserted into the aeration hole 32, oxygen inside the aeration head 3 can also be discharged outward along the air holes.

[0027] The drive assembly 7 includes a support plate 71 and a slip ring 73 that are slidably sleeved on the surface of the vertical pipe 4. The slip ring 73 is located inside the aeration head 3, and the support plate 71 is located outside the aeration head 3. A connecting rod 74 is fixed between the support plate 71 and the slip ring 73. A through hole 31 for the connecting rod 74 to pass through is opened on the bottom wall of the aeration head 3. Support rods 72 are fixed on both sides of the upper surface of the support plate 71. The top of the support rods 72 is fixedly connected to the frame plate 51.

[0028] Under normal circumstances, when oxygen enters the aeration head 3 along the vertical pipe 4, it is then discharged from the aeration hole 32 to achieve aeration. When the aeration hole 32 is severely blocked, preventing oxygen from being discharged, the air pressure above the slip ring 73 increases, thereby pushing the slip ring 73 to move downward along the vertical pipe 4. This pushes the support plate 71 down through the connecting rod 74, and the support rod 72 pulls the unblocking component 5 down, which in turn allows the needle 53 to be inserted into the aeration hole 32 to clear the blockage.

[0029] A spring 75 is fixed to the lower surface of the slip ring 73 and the inner bottom wall of the aeration head 3. After the aeration hole 32 resumes venting, the air pressure above the slip ring 73 decreases, and the spring force of the spring 75 causes the slip ring 73 to move upward and reset, thereby driving the support plate 71, support rod 72 and unblocking assembly 5 to move upward and reset as a whole.

[0030] Both the inner and outer walls of the slip ring 73 are fixed with sealing rings 76.

[0031] The sealing ring 76 can increase the sealing between the slip ring 73 and the surface of the vertical pipe 4, as well as the sealing between the slip ring 73 and the inner wall of the aeration head 3.

[0032] The cutting assembly 6 includes a vertical shaft 61 that penetrates the top wall of the aeration head 3. The vertical shaft 61 is rotatably connected to the top wall of the aeration head 3 through a sealed bearing. A round hole 54 is provided in the middle of the frame plate 51. The top end of the vertical shaft 61 passes through the round hole 54 and is fixed with a cutting blade 62. The bottom end of the vertical shaft 61 is located inside the vertical pipe 4 and is fixed with an impeller 63.

[0033] When oxygen flows through the vertical pipe 4, the airflow will drive the impeller 63 to rotate, which in turn drives the coaxial cutting blade 62 to rotate, cutting and breaking up the oxygen bubbles discharged from the aeration hole 32, so that the bubbles can fully contact the water and improve the aeration effect.

[0034] Working principle: Oxygen enters the vertical pipe 4 through the main air inlet pipe 1, then enters the aeration head 3, and finally exits from the aeration hole 32. During this process, the airflow drives the impeller 63 to rotate, which in turn drives the coaxial cutting blade 62 to rotate, cutting and breaking up the oxygen bubbles exiting from the aeration hole 32, allowing the bubbles to fully contact the water. If the aeration hole 32 is blocked, the air pressure above the slip ring 73 increases, thus pushing the slip ring 73 downward along the vertical pipe 4. This pushes the support plate 71 down through the connecting rod 74, and the support rod 72 pulls the unblocking component 5 down, allowing the needle 53 to insert into the aeration hole 32, thus clearing the blockage. After the aeration hole 32 resumes venting, the air pressure above the slip ring 73 decreases, and the spring force of the spring 75 causes the slip ring 73 to move upward and reset, thereby driving the support plate 71, support rod 72, and unblocking component 5 to move upward and reset as a whole.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
