[0004] However, in actual use, the siphon tube needs to be filled with liquid manually each time it is used, which is inconvenient and increases the workload of the staff, and cannot meet the needs of use. Utility Model Content

[0005] The purpose of this invention is to provide a siphon aerator to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A siphon aerator includes: a high-level water tank, an inlet water tank, and a low-level water tank; a water conveying component disposed between the high-level water tank and the inlet water tank for conveying liquid from the high-level water tank to the inlet water tank; a siphon component disposed between the inlet water tank and the low-level water tank for automatically transferring liquid from the inlet water tank to the low-level water tank; and an aeration component installed in the low-level water tank for aeration treatment of wastewater in the low-level water tank. The siphon component includes a diversion pipe inserted into the inlet water tank, a drain pipe connected to the aeration component installed on the upper half of the diversion pipe, a siphon tank installed at the upper end of the diversion pipe, a vacuum pump installed at the upper end of the siphon tank, and the suction port of the vacuum pump connected to the siphon tank.

[0007] As a preferred embodiment, the upper end of the siphon tank is also equipped with an air inlet pipe and an air blowing pipe, both of which are connected to the siphon tank, and the air blowing pipe is connected to an external blower.

[0008] As a preferred embodiment, a solenoid valve one is installed on the drainage pipe, a solenoid valve two is installed on the drainage pipe, a solenoid valve three is installed on the air inlet pipe, and a solenoid valve four is installed on the air blowing pipe.

[0011] As a preferred embodiment, the aeration assembly includes an aeration main pipe that connects to the drain pipe, with the end of the aeration main pipe extending into the low-water-level pool. A pair of branch pipes are also installed on one side of the aeration main pipe located in the low-water-level pool. Aeration pipes are installed at the ends of both the branch pipes and the aeration main pipe, and multiple sets of aeration heads are installed on the aeration pipes.

[0012] As a preferred embodiment, the aeration head includes a delivery pipe fixed to the aeration pipe, a nozzle is installed at the upper end of the delivery pipe, and a one-way valve is also installed on the delivery pipe.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: By closing solenoid valves two, three, and four, the air inside the siphon tank is extracted by a vacuum pump, creating a negative pressure environment inside the siphon tank. This allows the liquid in the inlet pool to be drawn into the siphon tank. Subsequently, solenoid valve one is closed, while solenoid valves two and three are opened. Under atmospheric pressure, the liquid in the siphon tank enters the drain pipe. Then, solenoid valve one is opened and solenoid valve three is closed, automatically transferring the liquid in the inlet pool to the low-level pool through siphon action. The operation is simple, eliminating the need for manual filling of the pipes with liquid, effectively reducing the workload of workers and better meeting usage needs. This utility model has a reasonable structure, allowing liquid to automatically enter the drainage and drain pipes before siphoning, facilitating subsequent siphoning operations. Its simple operation reduces the workload of workers and better meets usage needs. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0017] Example: Please refer to Figures 1-4 A siphon aerator includes: a high-level water tank 1, an inlet water tank 2, and a low-level water tank 3; a water conveying component disposed between the high-level water tank 1 and the inlet water tank 2 for conveying liquid from the high-level water tank 1 to the inlet water tank 2; a siphon component 4 disposed between the inlet water tank 2 and the low-level water tank 3 for automatically transferring liquid from the inlet water tank 2 to the low-level water tank 3; and an aeration component 5 installed in the low-level water tank 3 for aeration treatment of wastewater in the low-level water tank 3; the siphon component 4 includes a drain pipe 41 inserted into the inlet water tank 2, the upper half of which is fitted with a drain pipe that connects to the aeration component 5. 42. A siphon tank 43 is also installed at the upper end of the drainage pipe 41. A vacuum pump 44 is installed at the upper end of the siphon tank 43. The suction port of the vacuum pump 44 is connected to the siphon tank 43. In this embodiment, an air inlet pipe 45 and an air blowing pipe 46 are also installed at the upper end of the siphon tank 43. Both the air inlet pipe 45 and the air blowing pipe 46 are connected to the siphon tank 43. The air blowing pipe 46 is connected to an external blower. A solenoid valve 411 is installed on the drainage pipe 41. A solenoid valve 421 is installed on the drainage pipe 42. A solenoid valve 451 is installed on the air inlet pipe 45. A solenoid valve 461 is installed on the air blowing pipe 46.

[0018] The working principle of this utility model is as follows: When it is necessary to transfer the liquid in the inlet pool 2 to the low-level pool 3 through the siphon assembly 4, the solenoid valves 421, 451, and 461 are closed. Then, the vacuum pump 44 is started to extract the air from the siphon tank 43, thereby creating a negative pressure environment in the siphon tank 43, which can draw the liquid in the inlet pool 2 into the siphon tank 43. Then, the solenoid valve 411 is closed and the solenoid valves 421 and 451 are opened. Under the action of atmospheric pressure, the liquid in the siphon tank 43 will enter the drain pipe 42. Then, the solenoid valve 411 is opened and the solenoid valve 451 is closed. The liquid in the inlet pool 2 can be automatically transferred to the low-level pool 3 through the siphon action. The operation is simple and does not require manual filling of the pipe with liquid, which can effectively reduce the workload of the staff and thus better meet the needs of use. When it is necessary to aerate the liquid in the low-level water tank 3, close solenoid valve 1 411, solenoid valve 2 421, and solenoid valve 3 451, and open solenoid valve 461. Then, air is blown into the siphon tank 43 of the external blower box. The air enters the aeration component 5 through the drain pipe 42 and is then discharged. It comes into contact with the liquid in the low-level water tank 3, thus aerating the liquid in the low-level water tank 3.

[0019] As a further solution, the siphon assembly 4 is fixed to the outer wall of the inlet pool 2 by a fixing bracket 21.

[0020] As a further embodiment, the water conveying assembly includes a water conveying pipe 11 installed between the high-water level pool 1 and the inlet pool 2, a water pump 12 installed on the water conveying pipe 11, and the inlet port of the water conveying pipe 11 extending into the bottom of the high-water level pool 1.

[0021] The working principle of the water conveying assembly is as follows: When conveying water, the water pump 12 is started, and the liquid in the high water level pool 1 is transferred to the inlet pool 2 through the water conveying pipe 11.

[0022] As a further embodiment, the aeration assembly 5 includes an aeration main pipe 51 connected to the drain pipe 42. The end of the aeration main pipe 51 extends into the low-water level pool 3. A pair of branch pipes 52 are also installed on one side of the aeration main pipe 51 located in the low-water level pool 3. Aeration pipes 53 are installed at the ends of both the branch pipes 52 and the aeration main pipe 51. Multiple sets of aeration heads 6 are installed on the aeration pipes 53.

[0023] The working principle of the aeration component 5 is as follows: when the siphon component 4 transfers the liquid in the inlet pool 2 to the aeration main pipe 51, the liquid then enters the aeration pipe 53 and is sprayed out from the aeration head 6 on the aeration pipe 53, thus completing the liquid transfer. When the aeration process begins, the siphon assembly 4 blows air into the main aeration pipe 51. Then, part of the air enters the aeration pipe 53 through the branch pipe 52, and the other part of the air enters the aeration pipe 53 directly. Finally, the air is sprayed out from the aeration head 6 on the aeration pipe 53, which can aerate the liquid in the low water level pool 3.

[0024] As a further embodiment, the aeration head 6 includes a delivery pipe 62 fixed on the aeration pipe 53, a nozzle 61 is installed at the upper end of the delivery pipe 62, and a one-way valve 63 is also installed on the delivery pipe 62.

[0025] By setting a one-way valve 63, the liquid in the low-water-level pool 3 can be effectively prevented from flowing back into the aeration component 5. By setting a nozzle 61, air can be sprayed from multiple nozzles during aeration, which facilitates more thorough contact between the air and the liquid in the low-water-level pool 3, thereby improving the aeration effect.
