Description

Technical Field

[0001] This utility model relates to the field of mixing and aeration technology, and in particular to a submersible jet-flow mixing and aeration machine. Background Technology

[0002] Submersible aerators are commonly used in water treatment. They combine multiple functions such as flow propulsion, mixing, and aeration, playing a vital role in wastewater treatment, water body restoration, and aquaculture. In processes such as aeration tanks and oxidation ditches, they promote the thorough mixing of wastewater and activated sludge through flow propulsion and aeration, thereby enhancing the degradation of organic matter by microorganisms, improving wastewater treatment efficiency, preventing sludge deposition at the bottom of the tank, maintaining the sludge in suspension, and ensuring the continuous progress of biochemical reactions. In water treatment, they combine the characteristics of improving water quality, promoting ecological circulation, and energy efficiency, making them important equipment for wastewater treatment and water body maintenance.

[0003] However, existing technologies, such as Chinese Publication No. CN221420890U, "A Submersible Flow-Propelling Aerator," disclose a submersible flow-propelling aerator, including a support frame and a motor. The motor is mounted on the upper side of the support frame, and flow-propelling ports are arranged around the top of the inner wall of the support frame. A water flow regulating device is arranged on the inner wall of the flow-propelling ports, and multiple guide plates are arranged on the inner wall of the flow-propelling ports. The upper rear sides of the multiple guide plates are connected and fixed by a fixing plate, and a fixing knob is arranged on the upper front side of the flow-propelling ports. The fixing knob is used to control the left and right movement of the guide plates driven by the fixing plate to control the flow direction. The guide plates are fixed by inserting them into the holes of the fixing plate and the flow-propelling ports through a rotating shaft. The direction of water flow at the flow-propelling ports is controlled by adjusting the left and right offset angle of the rear side of the guide plates. Thus, the flow direction can be adjusted according to the water flow direction of the sewage tank, which can reduce the limitation of the aerator in the applicable sewage tank. Regardless of the installation direction, the flow direction can be controlled by adjusting the guide plates, thereby increasing the practicality of the aerator.

[0004] However, this device does not have a rotating aeration and stirring structure, which prevents the aeration device from covering a larger water body area during operation, from distributing bubbles evenly to various areas, from breaking the stagnant layer at the gas-liquid interface, and from making oxygen more easily dissolve in the water. Especially in sewage or wastewater treatment, it cannot ensure the normal operation of the biochemical treatment process, leading to the deposition of sludge, impurities, etc., increasing the frequency of sludge removal and maintenance costs. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art, such as the inability of aeration devices to cover a larger water body area during operation, the inability to evenly distribute bubbles to various areas, the inability to break the stagnant layer at the gas-liquid interface, and the inability to make oxygen more easily dissolve in water. Especially in sewage or wastewater treatment, it is impossible to ensure the normal operation of the biochemical treatment process, leading to the deposition of sludge, impurities, etc., increasing the frequency of dredging and maintenance costs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a submersible propulsion and stirring aerator, comprising an aeration shell body, a protective shell fixedly connected to the top of the inner surface of the aeration shell body, a main rod rotatably connected to the top of the aeration shell body, the outer surface of the main rod rotatably connected to the bottom of the protective shell, a rotating assembly provided on the outer surface of the main rod, the rotating assembly including a worm gear, the worm gear fixedly sleeved on the outer surface of the main rod, a worm engaged with the outer surface of the worm gear, a power rod fixedly embedded inside the worm, the outer surface of the power rod rotatably connected to the inside of the protective shell and extending out one end, an mounting sleeve fixedly connected to one side of the protective shell, a waterproof motor fixedly embedded on the inner surface of the mounting sleeve, the output end of the waterproof motor fixedly connected to the extended end of the power rod, the waterproof motor being fixed to one side of the protective shell by the mounting sleeve, the protective shell serving to protect the internal meshing elements.

[0007] In a preferred embodiment, a fixing sleeve is fixedly connected to the bottom of the main rod, and a submersible motor is fixedly embedded inside the fixing sleeve. The submersible motor is fixed to the top of the main rod through the fixing sleeve.

[0008] In a preferred embodiment, a rotating block is fixedly connected to the output end of the submersible motor, and multiple fan blades are fixedly connected to the outer surface of the rotating block. When the submersible motor is powered on, it will drive the rotating block and fan blades to rotate, and drive the ejected air to flow rapidly.

[0009] In a preferred embodiment, a plurality of fixing rods are fixedly connected to the outer surface of the submersible motor, and a protective sleeve is fixedly connected to the end of the plurality of fixing rods away from the submersible motor. The fixing rods and the protective sleeve on the outside of the submersible motor serve to protect the fan blades.

[0010] In a preferred embodiment, the aeration shell body has multiple air outlets, and multiple air outlet pipes are fixedly connected to the top of the aeration shell body. The bottom of the air outlet pipes is connected to the air outlets. Air enters the interior of the aeration shell body through the connecting pipes, flows through the air outlets, and finally sprays out from the air outlet pipes.

[0011] In a preferred embodiment, a rotating plate is fixedly connected to the bottom of the main rod, and two support plates are fixedly connected to the top of the rotating plate. An open sealing ring is fixedly connected to the top of the two support plates. The top of the open sealing ring is located on the inner surface of the aeration shell body. Because the opening direction of the open sealing ring is the same as the output end of the submersible motor, the rotating plate and support plates that rotate with the main rod will also drive the open sealing ring, so that the air outlet changes with the stirring direction of the submersible motor.

[0012] In a preferred embodiment, the open sealing ring and multiple air outlets are located on the same circumference, and the opening direction of the open sealing ring is the same as the output end of the submersible motor. The open sealing ring can block air outlets that are not in the same direction as the output end of the submersible motor.

[0013] In a preferred embodiment, the outer surface of the aeration shell body is connected to a connecting pipe, and the end of the connecting pipe away from the aeration shell body is connected to a blower, so that the blower located above the water surface can do work and blow air into the interior of the aeration shell body through the connecting pipe.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] This invention features a rotating aeration and stirring structure, which allows the aeration device to cover a larger water body during operation. This enables bubbles to be evenly distributed in various areas, breaking the stagnant layer at the gas-liquid interface and making it easier for oxygen to dissolve in the water. Especially in sewage or wastewater treatment, this ensures the normal operation of the biochemical treatment process, preventing the deposition of sludge and impurities, and reducing the frequency of sludge removal and maintenance costs.

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a submersible propulsion aerator, including an aeration shell body 1, a protective shell 2 fixedly connected to the top of the inner surface of the aeration shell body 1, a main rod 3 rotatably connected to the top of the aeration shell body 1, the outer surface of the main rod 3 rotatably connected to the bottom of the protective shell 2, a rotating assembly provided on the outer surface of the main rod 3, the rotating assembly including a worm gear 4, the worm gear 4 fixedly sleeved on the outer surface of the main rod 3, a worm 5 meshing with the outer surface of the worm gear 4, a power rod 6 fixedly embedded inside the worm 5, the outer surface of the power rod 6 rotatably connected to the inside of the protective shell 2 and extending out one end, an installation sleeve 7 fixedly connected to one side of the protective shell 2, a waterproof motor 8 fixedly embedded on the inner surface of the installation sleeve 7, the output end of the waterproof motor 8 fixedly connected to the extended end of the power rod 6, when the waterproof motor 8 is energized, it will drive the power rod 6 to rotate inside the protective shell 2, and the worm 5, which rotates with the power rod 6, will drive the main rod 3 to rotate under the meshing action of the worm gear 4, so that the stirring direction of the submersible motor 10 changes.

[0025] like Figures 1 to 5 As shown, a fixing sleeve 9 is fixedly connected to the bottom of the main rod 3, and a submersible motor 10 is fixedly embedded inside the fixing sleeve 9. The submersible motor 10 is fixed to the top of the main rod 3 through the fixing sleeve 9.

[0026] like Figures 1 to 5 As shown, a rotating block 11 is fixedly connected to the output end of the submersible motor 10, and multiple fan blades 12 are fixedly connected to the outer surface of the rotating block 11. When the submersible motor 10 is powered on, it will drive the rotating block 11 and the fan blades 12 to rotate, and drive the ejected air to flow rapidly.

[0027] like Figures 1 to 5 As shown, multiple fixing rods 13 are fixedly connected to the outer surface of the submersible motor 10. A protective sleeve 14 is fixedly connected to one end of the multiple fixing rods 13 away from the submersible motor 10. The fixing rods 13 and the protective sleeve 14 on the outside of the submersible motor 10 serve to protect the fan blades 12.

[0028] like Figures 1 to 5As shown, the aeration shell body 1 has multiple air outlets 15, and multiple air outlet pipes 16 are fixedly connected to the top of the aeration shell body 1. The bottom of the air outlet pipe 16 is connected to the air outlet 15. Air enters the interior of the aeration shell body 1 through the connecting pipe 20, flows through the air outlet 15, and finally sprays out from the air outlet pipe 16.

[0029] like Figures 1 to 5 As shown, a rotating plate 17 is fixedly connected to the bottom of the main rod 3, and two support plates 18 are fixedly connected to the top of the rotating plate 17. An open sealing ring 19 is fixedly connected to the top of the two support plates 18. The top of the open sealing ring 19 is set on the inner surface of the aeration shell body 1. Because the opening direction of the open sealing ring 19 is the same as the output end of the submersible motor 10, the rotating plate 17 and support plates 18 that rotate with the main rod 3 will also drive the open sealing ring 19, so that the air outlet changes with the stirring direction of the submersible motor 10.

[0030] like Figures 1 to 5 As shown, the open sealing ring 19 and multiple air outlets 15 are located on the same circumference. The opening direction of the open sealing ring 19 is the same as the output end of the submersible motor 10. The open sealing ring 19 can block the air outlets 15 that are not in the same direction as the output end of the submersible motor 10.

[0031] like Figures 1 to 5 As shown, a connecting pipe 20 is connected to the outer surface of the aeration shell body 1. A blower 21 is connected to the end of the connecting pipe 20 away from the aeration shell body 1, so that the blower 21 located above the water surface can do work and blow air into the interior of the aeration shell body 1 through the connecting pipe 20.

[0032] Working principle: First, the aeration shell body 1 and the device are placed inside the target water area. Then, the blower 21 located above the water surface works, and the blower 21 introduces air into the aeration shell body 1 through the connecting pipe 20, flows through the air outlet 15, and finally sprays it out from the air outlet pipe 16. Then, the external power supply of the submersible motor 10 is turned on. The submersible motor 10 is fixed to the top of the main rod 3 by the fixing sleeve 9. The fixing rod 13 and the protective sleeve 14 on the outside of the submersible motor 10 protect the fan blade 12. After the submersible motor 10 is powered on, it will drive the rotating block 11 and the fan blade 12 to rotate, and drive the sprayed air to flow rapidly. This is to make the aeration more uniform. The external power supply to start the waterproof motor 8 is activated. The waterproof motor 8 is fixed to one side of the protective shell 2 by the mounting sleeve 7. The protective shell 2 protects the internal meshing components. After the waterproof motor 8 is powered on, it will drive the power rod 6 to rotate inside the protective shell 2. The worm 5, which rotates with the power rod 6, will drive the main rod 3 to rotate under the meshing action of the worm wheel 4, so that the stirring direction of the submersible motor 10 changes. Because the opening direction of the opening sealing ring 19 is the same as the output end of the submersible motor 10, the rotating plate 17 and the support plate 18, which rotate with the main rod 3, will also drive the opening sealing ring 19, so that the air outlet changes with the stirring direction of the submersible motor 10.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
