Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, specifically an aeration blower for wastewater treatment. Background Technology

[0002] An aeration blower for wastewater treatment is a device used to provide oxygen during the wastewater treatment process. Its main function is to increase the contact area between wastewater and oxygen by introducing air into the wastewater treatment tank or aeration tank, thereby improving the oxidation efficiency of the wastewater and achieving the purpose of removing organic matter and purifying water quality. Currently, Roots blowers are commonly used for aeration.

[0003] In existing sewage treatment aeration blowers, the motor typically drives the impeller to rotate, drawing in air and pressurizing it before it is introduced into the sewage tank for treatment. During operation, the impeller and belt generate significant heat at high speeds, which accelerates belt wear. This not only greatly reduces the belt's lifespan but also weakens its elasticity after prolonged operation due to overheating, affecting rotational efficiency, reducing stability, and resulting in poor performance. Summary of the Invention

[0004] The purpose of this invention is to provide an aeration blower for wastewater treatment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an aeration blower for sewage treatment, comprising a base, a motor and an impeller box being fixedly mounted on the top surface of the base, a wheel assembly being fixedly sleeved on the outer surface of the motor shaft and the outer surface of the impeller box shaft, a movable component being fixedly mounted on the side of the base, a distribution component being fixedly sleeved on the front of the movable component, one end of the distribution component being sleeved in the wheel assembly and communicating with the inside of the wheel assembly, an air inlet pipe being fixedly connected to the top of the impeller box, a silencer component being fixedly connected to the top of the air inlet pipe, a drain pipe being fixedly connected to both sides of the distribution component, one of the drain pipes being fixedly connected to the silencer component, and a belt being sleeved on the outer side of the wheel assembly;

[0006] The distribution assembly includes a cooling sleeve, a partition plate, an intermediate sleeve, and an inlet pipe, wherein the cooling sleeve is rotatably sleeved with the rotating wheel assembly.

[0007] Preferably, the impeller assembly includes a wheel body, a cooling chamber, and a communicating chamber. The cooling chamber is located inside the wheel body, and the communicating chamber is located inside the wheel body and communicates with the cooling chamber. The cooling chamber is an annular chamber. There are two impeller assemblies, and the two wheel bodies are respectively fixedly sleeved on the outer surface of the motor shaft and the outer surface of the impeller box shaft.

[0008] Preferably, both the outer surface of the motor shaft and the outer surface of the impeller box shaft are provided with intermediate grooves, and the intermediate grooves are connected to the communicating cavity.

[0009] Preferably, the movable component includes a protective frame, a connecting frame, and an electric push rod. The electric push rod is fixedly installed on the front of the base. The protective frame is located outside the rotating wheel assembly. The connecting frame is fixedly connected to the movable end of the electric push rod and is fixedly connected to the protective frame.

[0010] Preferably, the cooling sleeve is fixedly fitted onto the front of the protective frame and onto the front of the wheel body, the partition plate is fixedly connected inside the cooling sleeve, the intermediate sleeve is fixedly connected between the two cooling sleeves, and the liquid inlet pipe is fixedly connected to the front of the intermediate sleeve.

[0011] Preferably, the muffler assembly includes a muffler sleeve, an inner cavity, an intermediate ring, a muffler ring, a heat exchange sleeve, an intermediate hole, and a return pipe. The muffler sleeve is fixedly connected to the top of the intake pipe, the inner cavity is opened inside the muffler sleeve, the intermediate ring is fixedly connected to the inside of the inner cavity, and the muffler ring is fixedly sleeved on the inner surface of the intermediate ring.

[0012] Preferably, the heat exchange jacket is fixedly connected to the top of the silencing jacket, the intermediate hole is opened on the top surface of the silencing jacket and communicates with the heat exchange jacket, and the return pipe is fixedly connected to the side of the heat exchange jacket.

[0013] Preferably, the side of the silencing sleeve has an opening, and the drain pipe is connected to the opening.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. This invention utilizes a movable component to assemble the distribution component. The lateral movement of the movable component switches the state of the distribution component. In non-starting mode, the distribution component is fitted into the rotating wheel assembly. With the partition plate in the distribution component, a single cooling sleeve is divided into an inlet chamber and an outlet chamber. Furthermore, the connection between the cooling chamber and the intermediate groove in the rotating wheel assembly guides cooling water in during wheel rotation for heat exchange, achieving rapid cooling of the wheel and belt. This prevents overheating that could reduce belt lifespan and reduce elasticity and transmission efficiency, significantly improving belt lifespan and stability, enhancing rotational aeration, and ensuring timely cooling during operation for optimal performance.

[0016] 2. This invention adds a silencing component to the top of the inhalation tube, which works in conjunction with the internal cavity and silencing ring. The cooled exhaust hot water is introduced into the silencing component, forming a flowing water ring on the outside of the silencing ring. This allows the noise during the gas inhalation process to undergo primary absorption by the silencing ring, followed by secondary absorption by the flowing hot water, thus reducing the noise propagation energy and improving the silencing effect.

[0017] 3. This invention introduces cooled water into the silencing component, which, together with the intake airflow, helps to eliminate noise while cooling the incoming hot water through the heat exchange jacket. Without adding additional cooling equipment, it provides auxiliary cooling for the cooled hot water, improves the cooling effect after recirculation, reduces the energy supply for intermediate cooling of the circulating cooling water, saves energy, improves the circulating cooling effect, and has good performance.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0028] like Figures 1 to 8 As shown, this embodiment of the invention provides an aeration blower for sewage treatment, including a base 1. A motor 2 and an impeller box 3 are fixedly installed on the top surface of the base 1. A rotating wheel assembly 4 is fixedly sleeved on the outer surface of the rotating shaft of the motor 2 and the outer surface of the rotating shaft of the impeller box 3. A moving assembly 8 is fixedly provided on the side of the base 1. A distribution assembly 9 is fixedly sleeved on the front of the moving assembly 8. One end of the distribution assembly 9 is sleeved in the rotating wheel assembly 4 and communicates with the inside of the rotating wheel assembly 4. An air inlet pipe 6 is fixedly connected to the top of the impeller box 3. A silencer assembly 10 is fixedly connected to the top of the air inlet pipe 6. Drain pipes 11 are fixedly connected to both sides of the distribution assembly 9. One drain pipe 11 is fixedly connected to the silencer assembly 10. A belt 5 is sleeved on the outer side of the rotating wheel assembly 4.

[0029] The distribution assembly 9 includes a cooling sleeve 91, a partition plate 92, an intermediate sleeve 93, and an inlet pipe 94. The cooling sleeve 91 is rotatably sleeved with the rotating wheel assembly 4.

[0030] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, during use, before starting the motor 2, the moving component 8 is started first, causing the electric push rod 83 to move the connecting frame 82 laterally and the protective frame 81 laterally, so that the cooling sleeve 91 in the distribution component 9 is fitted into the front of the wheel body 41, and the protective frame 81 is located outside the wheel assembly 4. The motor 2 is started and drives the corresponding installed wheel assembly 4 to rotate, causing the belt 5 to rotate and driving another rotating component 4 to rotate, thereby causing the impeller inside the impeller box 3 to rotate for aeration. During the aeration process, the external circulating water pump is started to introduce cooling water into the inlet pipe 94. The cooling water is introduced into the intermediate sleeve 93 and flows into the internal partial cavity of the cooling sleeve 91, flows along the partition plate 92 to the inside of the wheel body 41, and flows along the intermediate groove 7 into the cooling chamber 42, so that the temperature of the wheel body 41 and the belt decreases. After heat exchange, the hot water flows out in the opposite direction along the other half of the internal space of the cooling sleeve 91.

[0031] First, the assembly of the distribution component 9 is completed by using the moving component 8. With the lateral movement of the moving component 8, the state of the distribution component 9 is switched. In the non-starting state, the distribution component 9 is fitted into the wheel assembly 4. With the partition plate 92 in the distribution component 9, the individual cooling sleeve 91 is divided into an inlet chamber and an outlet chamber. With the connection between the cooling chamber 42 in the wheel assembly 4 and the intermediate groove 7, the cooling water is guided into the wheel body during operation and heat exchange is carried out. This achieves rapid cooling of the wheel body 41 and the belt 5, avoiding overheating that would reduce the life of the belt 5 and prevent the belt 5 from losing elasticity and transmission efficiency due to overheating. This greatly improves the service life and stability of the belt 5, improves the rotation aeration effect, and the cooling process is achieved during operation, resulting in timely cooling and good performance.

[0032] Example 2: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, after cooling is completed, the hot water discharged from a set of rotating wheel assemblies 4 is introduced into the silencing assembly 10 through the drain pipe 11. The hot water enters and fills the internal cavity 102, and enters the heat exchange jacket 105 through the middle hole 106. It then flows back to the cooling water pool through the return pipe 107. At this time, the air drawn in flows rapidly at the heat exchange jacket 105. On the one hand, this cools the hot water in the heat exchange jacket 105. On the other hand, the noise during the air intake process is further transmitted to the internal cavity 102 and the liquid inside the heat exchange jacket 105 after being initially absorbed by the sound-absorbing material in the silencing ring 104. This further absorbs the noise energy, thus completing the silencing and cooling.

[0033] First, by adding a silencing component 10 to the top of the suction pipe, in conjunction with the internal cavity 102 and the silencing ring 104, the cooled exhaust hot water is introduced into the silencing component 10, forming a flowing water ring on the outside of the silencing ring 104. This allows the noise during the gas intake process to undergo primary absorption by the silencing ring 104, followed by secondary absorption by the flowing hot water, reducing the noise propagation energy and improving the silencing effect.

[0034] In addition, by introducing the cooled water into the silencer assembly 10, and in conjunction with the intake airflow, noise is eliminated while the hot water is cooled by the heat exchange jacket 105. Without adding additional cooling equipment, the cooled hot water is assisted in cooling, improving the cooling effect after recirculation, reducing the energy supply for intermediate cooling of the circulating cooling water, saving energy, improving the circulating cooling effect, and achieving good performance.

[0035] The impeller assembly 4 includes a wheel body 41, a cooling chamber 42, and a connecting chamber 43. The cooling chamber 42 is located inside the wheel body 41, and the connecting chamber 43 is located inside the wheel body 41 and is connected to the cooling chamber 42. The cooling chamber 42 is an annular chamber. There are two impeller assemblies 4. The two wheel bodies 41 are respectively fixedly sleeved on the outer surface of the motor 2 shaft and the outer surface of the impeller box 3 shaft. The outer surfaces of the motor 2 shaft and the impeller box 3 shaft are both provided with intermediate grooves 7, which are connected to the connecting chambers 43.

[0036] Rotation is achieved through the impeller assembly 4 and belt 5, which rotates the impeller to supply aeration. Cooling water is introduced into the connecting cavity 43 for overall cooling. The connecting cavity 43 is connected to the intermediate groove 7 to allow cooling water to enter. The wheel body 41 has an internal hole in the middle for assembling the shaft. The front end of the shaft is located inside the internal hole, leaving space for the cooling sleeve 91 to be fitted. The surface of the cooling sleeve 91 is provided with a sealing ring (not shown in the figure) to improve the sealing effect.

[0037] The movable component 8 includes a protective frame 81, a connecting frame 82, and an electric push rod 83. The electric push rod 83 is fixedly installed on the front of the base 1. The protective frame 81 is located on the outside of the rotating wheel assembly 4. The connecting frame 82 is fixedly connected to the movable end of the electric push rod 83 and is fixedly connected to the protective frame 81.

[0038] The movable component 8 controls the position of the protective frame 81 to maintain good protection, and controls the position of the dispensing component 9 to enable insertion and removal, and provides space for disassembling the belt 5 after removal.

[0039] The cooling sleeve 91 is fixedly sleeved on the front of the protective frame 81 and sleeved in the front of the wheel body 41. The partition plate 92 is fixedly connected inside the cooling sleeve 91. The intermediate sleeve 93 is fixedly connected between the two cooling sleeves 91. The liquid inlet pipe 94 is fixedly connected to the front of the intermediate sleeve 93.

[0040] The partition plate 92 divides the interior of the cooling sleeve 91 into two spaces, one for cooling water inlet and the other for cooling water inlet, to maintain stable cooling during operation.

[0041] The silencing assembly 10 includes a silencing sleeve 101, an internal cavity 102, an intermediate ring 103, a silencing ring 104, a heat exchange sleeve 105, an intermediate hole 106, and a return pipe 107. The silencing sleeve 101 is fixedly connected to the top of the air inlet pipe 6. The internal cavity 102 is opened inside the silencing sleeve 101. The intermediate ring 103 is fixedly connected to the inside of the internal cavity 102. The silencing ring 104 is fixedly sleeved on the inner surface of the intermediate ring 103. The heat exchange sleeve 105 is fixedly connected to the top of the silencing sleeve 101. The intermediate hole 106 is opened on the top surface of the silencing sleeve 101 and communicates with the heat exchange sleeve 105. The return pipe 107 is fixedly connected to the side of the heat exchange sleeve 105. The side of the silencing sleeve 101 has an opening, and the drain pipe 11 is connected to the opening.

[0042] The noise reduction component 10 achieves dual noise reduction through the noise reduction ring 104 and the internal water flow, and works with the intake airflow to cool the internal water flow, thereby improving the efficiency of the circulating cooling and reducing energy input.

[0043] The working principle and usage process of this invention: During use, before starting the motor 2, the moving component 8 is started first, causing the electric push rod 83 to move the connecting frame 82 laterally, and causing the protective frame 81 to move laterally, so that the cooling sleeve 91 in the distribution component 9 is fitted into the front of the wheel body 41, and the protective frame 81 is located outside the wheel assembly 4. The motor 2 is started and drives the corresponding installed wheel assembly 4 to rotate, causing the belt 5 to rotate, and driving another rotating component 4 to rotate, thereby causing the impeller inside the impeller box 3 to rotate, performing aeration. During the aeration process, the external circulating water pump is started, and cooling water is introduced into the liquid inlet pipe 94. The cooling water is introduced into the intermediate sleeve 93 and flows into the internal partial cavity of the cooling sleeve 91, flows along the partition plate 92 to the inside of the wheel body 41, and flows along the intermediate groove 7. The hot water enters the cooling chamber 42, causing the temperature of the wheel body 41 and belt to decrease. After heat exchange, the hot water flows out in the opposite direction along the other half of the internal space of the cooling jacket 91. After cooling is completed, the hot water discharged from a set of rotating wheel assemblies 4 is introduced into the silencing assembly 10 through the drain pipe 11. The hot water enters the internal cavity 102 and fills it, and enters the heat exchange jacket 105 through the intermediate hole 106. It then flows back to the cooling water pool through the return pipe 107. At this time, the air drawn in flows rapidly at the heat exchange jacket 105. On the one hand, this cools the hot water in the heat exchange jacket 105. On the other hand, the noise during the air intake process is further transmitted to the internal cavity 102 and the liquid inside the heat exchange jacket 105 after being initially absorbed by the sound-absorbing material in the silencing ring 104, thus further absorbing the noise energy and completing the silencing and cooling.
