Description

Technical Field

[0001] This utility model relates to the field of aerator technology, and in particular to an adjustable submersible aerator. Background Technology

[0002] Aeration is one of the most important processes in the activated sludge process for wastewater biological treatment. Submersible aerators are driven by submersible motors that rotate impellers at high speeds. The impellers generate strong centrifugal force, creating a negative pressure zone around the impeller, thus generating self-suction. A large amount of fresh air from the atmosphere is continuously drawn in through the suction pipe. After mixing, the air is guided to a specific direction or area for aeration by the fixed shell. The ejected gas-liquid mixture produces a stirring and convection effect. Due to the generation of numerous microbubbles, excellent oxygenation is achieved, ensuring thorough mixing of activated sludge, wastewater, and oxygen, thereby rapidly and efficiently purifying wastewater.

[0003] Patent CN207811354U discloses a submersible aerator, including an air inlet pipe, a submersible electric pump, an impeller, a water inlet, and a mixing chamber. The mixing chamber is cylindrical and includes a top cover, a bottom cover, and side walls. The side walls can rotate freely around the center. Water spray pipes are provided on the side walls, with 3-4 spray pipes. A gear ring is fixedly provided on the upper side of the inner surface of the side walls. An auxiliary rotating shaft is provided on the top cover. A gear that meshes with the gear ring is provided at the bottom of the auxiliary rotating shaft. A belt drive pulley is provided at the top. A belt driven pulley is provided on the output shaft of the submersible electric pump. A belt is provided between the belt drive pulley and the belt driven pulley.

[0004] The aforementioned patents still have the following technical defects: the aerator impeller can only rotate horizontally, and its agitation range for the water is limited, making it unable to meet a wider range of aeration needs. Utility Model Content

Detailed Implementation

[0022] Example 1

[0023] like Figures 1-4 As shown in the figure, the adjustable submersible aerator proposed in this embodiment includes an aerator main body, a mounting bracket 1, an outer cover 4, a fan blade 6, an air inlet hose 12, and a lifting drive mechanism.

[0024] The main aerator unit includes a mounting base 2, a cylinder 3, a vertical rotating shaft 5, a rotating housing 7, an air inlet pipe 8, a submersible motor 27, and a stirring mechanism.

[0025] Submersible motor 27 and cylinder 3 are respectively installed at the upper and lower ends of mounting base 2. Vertical rotating shaft 5 is rotatably installed on mounting base 2. The bottom end of mounting base 2 is equipped with a first sealing ring for sealing vertical rotating shaft 5. The output shaft of submersible motor 27 is connected to vertical rotating shaft 5. Fan blade 6 is installed at the bottom end of vertical rotating shaft 5. Air inlet hose 12 is connected to the inside of cylinder 3. Air inlet hose 12 is a flexible metal hose with a float ball 13 connected to its outer end. Air inlet pipe 8 is rotatably installed at the bottom of cylinder 3 and is connected to the inside of cylinder 3. Rotating housing 7 is connected to the bottom end of air inlet pipe 8. Outer cover 4 is fixedly connected to cylinder 3. Rotating housing 7 and stirring mechanism are both located inside outer cover 4.

[0026] The stirring mechanism includes a transmission assembly and multiple stirring assemblies. Each stirring assembly includes a rotating tube 9 and multiple stirring plates 10. The rotating tube 9 is rotatably mounted on the rotating housing 7. All stirring plates 10 are mounted on the rotating tube 9. A one-way valve 20 is installed on the rotating tube 9. The one-way valve 20 only allows gas to flow from one side of the inner end of the adjacent rotating housing to the other side. The transmission assembly includes a second bevel gear 25, a transmission shaft 26, a transverse rotating shaft 21, a first bevel gear 22, and a connecting frame 23. The transmission shaft 26 is rotatably mounted on the rotating housing 7. The lower end of the transmission shaft 26 is connected to the outer cover 4, and its upper end is connected to the second bevel gear 25. The number of transverse rotating shaft 21, first bevel gear 22, and connecting frame 23 is the same as the number of stirring assemblies. The transverse rotating shaft 21 is rotatably mounted inside the rotating housing 7. The transverse rotating shaft 21 is connected to the corresponding side rotating tube 9 through the connecting frame 23. The first bevel gear 22 is mounted on the transverse rotating shaft 21 and meshes with the second bevel gear 25.

[0027] The lifting drive mechanism is installed on the upper end of the mounting bracket 1 to drive the mounting base 2 to lift.

[0028] A second sealing ring for sealing the air intake pipe 8 is installed on the bottom inner side of the cylinder 3, and a second sealing ring for sealing the rotating pipe 9 is installed on the rotating housing 7.

[0029] like Figure 1 The vertical rod of the mounting bracket 1 is inserted deep into the bottom of the pool and fixedly installed. During aeration, the submersible motor 27 is started to drive the vertical rotating shaft 5 and the fan blade 6 to rotate. The rotating fan blade 6 draws outside air into the cylinder 3 through the air intake hose 12. It should be noted that a filter screen is installed on the inner and outer ends of the air intake hose 12 to block larger impurities from entering. The gas that enters the cylinder 3 then flows to the inner side of the air intake pipe 8 and the rotating housing 7, and finally enters the rotating pipe 9 and is discharged into the water through the rotating pipe 9, so that the air and water are mixed.

[0030] In this technical solution, multiple through holes communicating with the rotating tube 9 can also be opened on the stirring plate 10, which makes the outflowing gas distribution range wider.

[0031] The rotation of the vertical shaft 5 drives the rotating shell 7 to rotate horizontally, which in turn drives the rotating tube 9 and the stirring plate 10 to rotate horizontally, thus agitating the water. During this process, since the second bevel gear 25 is stationary relative to the cylinder 3, when multiple first bevel gears 22 roll on the second bevel gear 25, the first bevel gears 22 rotate, which in turn drives the rotating tube 9 to rotate, and multiple stirring plates 10 rotate around the rotating tube 9, thus achieving up-and-down agitation of the water, thereby obtaining a wider aeration range.

[0032] Example 2

[0033] like Figure 1 and Figure 2 As shown, this embodiment proposes an adjustable submersible aerator. Compared to Embodiment 1, in this embodiment, the lifting drive mechanism includes a servo motor 18, a transmission assembly, and two sets of winding assemblies. Two mounting plates 11 are arranged side-by-side on the upper end of the mounting bracket 1. The winding assembly includes a mounting shaft 14, two winding reels 15, and two winding ropes 19. The two ends of the mounting shaft 14 are rotatably mounted on the two side mounting plates 11. Both winding reels 15 are mounted on the mounting shaft 14. One end of each winding rope 19 is fixed to the two side winding reels 15, and the other end of each winding rope 19 movably passes through the upper end of the mounting bracket 1 and is fixedly connected to the mounting base 2. The transmission assembly includes the same... The device consists of a step belt 17 and two synchronous pulleys 16, which are respectively mounted on the two side mounting shafts 14. The two synchronous pulleys 16 are connected by a synchronous belt 17. A servo motor 18 is mounted on the mounting plate 11 and its output shaft is connected to one side mounting shaft 14. When the servo motor 18 is started, it drives the corresponding side mounting shaft 14 to rotate. Under the transmission action of the transmission components, the other side mounting shaft 14 rotates synchronously, which in turn drives multiple winding reels 15 to rotate synchronously. By adjusting the rotation direction of the winding reels 15, the winding and unwinding operations of the winding rope 19 can be realized, thereby controlling the height of the mounting base 2 and the main body of the aerator to meet the aeration requirements of different water depths.

[0034] The first outer cover 241 and the second outer cover 242 are respectively installed on the two mounting plates 11. The synchronous belt 17 and the two synchronous pulleys 16 are located inside the first outer cover 241. The servo motor 18 is located inside the second outer cover 242. The lower end of the second outer cover 242 is open. The first outer cover 241 and the second outer cover 242 are designed for protective purposes.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
