[0034] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Example 1

[0037] Please refer to Figure 1-3 An intermittent aeration mechanism for treating sewage includes a support 100, which is hollow inside. A blower 110 is provided at the input end of the support 100. An air inlet pipe 120 is provided inside the support 100. The pipe wall of the air inlet pipe 120 is provided with a plurality of air inlet holes 130. The bottom end of the air inlet pipe 120 is connected to a plurality of air outlet pipes 140. The top surface of the plurality of air outlet pipes 140 is provided with a plurality of air outlet holes 150.

[0038] The drive assembly 200 is used to drive the intake pipe 120 to rotate. The drive assembly 200 includes a motor 210, a first sector gear 220 and a second sector gear 230. The output end of the motor 210 passes through the bracket 100, and the first sector gear 220 is provided at the output end of the motor 210. The second sector gear 230 is provided at the upper end of the intake pipe 120, and the first sector gear 220 and the second sector gear 230 mesh.

[0039] The rotating assembly 300 is located at the lower end of the air intake pipe 120. The rotating assembly 300 includes a rotating block 310 and a first bearing 320. The first bearing 320 is sleeved on the bottom end of the bracket 100 and located on the inner top of the rotating block 310. The bottom end of the air intake pipe 120 enters the interior of the rotating block 310. In the horizontal direction, a plurality of air outlet pipes 140 extend from the interior of the rotating block 310 to the outside.

[0040] Through the above structural design, the support 100 is L-shaped and hollow inside. The output end of the motor 210 is inserted into the interior of the support 100 from one side. The output end of the motor 210 is equipped with a first sector gear 220. Through the meshing of the first sector gear 220 and the second sector gear 230, the motor 210 is started, which allows the air inlet pipe 120 to rotate and controls the rotation speed. The rotating component 300 is used to rotate the air outlet pipe 140. The support 100 does not participate in the rotation. The bottom end of the support 100 is connected to the rotating block through the bearing. The air inlet pipe 120 can drive the air outlet pipe 140 and the rotating block to rotate. The rotating component 300 and multiple air outlet pipes 140 are set at the bottom of the air inlet pipe 120, so that multiple air outlet pipes 140 can rotate and aerate, which is conducive to comprehensive and uniform aeration, improves aeration efficiency, and allows sewage and air to be fully mixed. This mechanism has a simple transmission method and simple structure, which meets people's growing sewage treatment needs.

[0041] Specifically, a floating block 160 is provided on the support 100, and the bottom surface of the motor 210 and the bottom surface of the fan 110 are both provided on the top surface of the floating block 160.

[0042] Through the above structural design, when the water level is higher than the structure, the floating block 160 can ensure that the motor 210 and the fan 110 can always stay on the water surface, which is beneficial to protecting the safety of the motor 210 and the fan 110.

[0043] Specifically, an airflow regulating valve 170 is provided on the end of the bracket 100 near the fan 110.

[0044] Through the above structural design, the stirring frequency is achieved by the airflow regulating valve 170. Increasing the airflow increases the stirring frequency and the stirring intensity of the water; decreasing the airflow decreases the stirring frequency and the stirring intensity of the water.

[0045] Specifically, an air collecting cylinder 400 is provided on one end of the bracket 100 near the rotating component 300, and the air collecting cylinder 400 is connected to the inside of the bracket 100.

[0046] With the above structural design, in the initial state, the gas collecting cylinder 400 is filled with sewage. When the blower 110 starts and the airflow regulating valve 170 is opened, airflow enters from the inlet pipe 120. As the gas accumulates in the gas collecting cylinder 400, the water level in the gas collecting cylinder 400 and the water level in the outlet pipe 140 are pushed down. When the liquid level drops to the height of the outlet pipe 140, the gas flows out from the outlet in the outlet pipe 140, forming a continuous airflow within the outlet pipe 140. This airflow creates a stirring effect on the water in the tank. After the gas in the gas collecting cylinder 400 is discharged, the gas collecting cylinder 400 and the outlet pipe 140 are refilled with water, returning to the initial state. This cycle repeats continuously, achieving stirring of the water. This process can also be called the air siphon stirring process.

[0047] Specifically, the intermittent aeration mechanism for treating sewage also includes a second bearing 500, a mounting column 600, and a base 700. The second bearing 500 is sleeved on the top of the mounting column 600 and is located on the bottom of the rotating block 310. The bottom of the mounting column 600 is located on the base 700.

[0048] Through the above structural design, the function of the second bearing 500 is to prevent the drive assembly 200 from rotating the base 700. When the water level is lower than the floating plate, the function of the base 700 is to provide a standing platform for the mechanism. Example 2

[0049] The intermittent aeration mechanism for treating wastewater provided in Example 1 is further optimized, specifically, as follows: Figure 1-3 As shown, the floating block 160 has the same shape and size as the base 700.

[0050] The above structural design helps to stabilize the center of gravity.

[0051] Specifically, the floating block 160 is made of any one of polyethylene, polyurethane, polypropylene, and rigid polyvinyl chloride.

[0052] Through the above structural design, in this embodiment, the floating block 160 is made of polyethylene, but other materials can also be used depending on different needs.

[0053] Specifically, the base 700 is made of any one of aluminum-lithium alloy, titanium-aluminum alloy, magnesium alloy, beryllium alloy, and titanium alloy.

[0054] Through the above structural design, in this embodiment, the base 700 is made of aluminum-lithium alloy, but other materials can also be used depending on different needs. Example 3

[0055] The intermittent aeration mechanism for treating wastewater provided in Example 1 or 2 is further optimized, such as... Figure 1-3 As shown, there are four exhaust pipes 140, which are inserted into the bottom of the intake pipe 120 in a cross shape.

[0056] Through the above structural design, multiple air outlet pipes 140 can rotate for aeration, which is conducive to comprehensive and uniform aeration, improves aeration efficiency, and allows sewage and air to be fully mixed. The transmission method of this mechanism is simple and the structure is easy to implement, meeting people's growing demand for sewage treatment.

[0057] The intermittent aeration mechanism for treating wastewater provided by this utility model is used as follows:

[0058] In the initial state of the device, the gas collection cylinder 400 is filled with sewage. When the blower 110 is started, the air flow regulating valve 170 is opened, and the air flow enters from the air inlet pipe 120. As the gas accumulates in the gas collection cylinder 400, the water level in the gas collection cylinder 400 and the water level in the air outlet pipe 140 are pushed down. When the liquid level drops to the height of the air outlet pipe 140, the gas flows out from the air outlet in the air outlet pipe 140 and forms a continuous air flow in the air outlet pipe 140. The air flow creates a stirring effect on the water in the tank. After the gas in the air collecting cylinder 400 is discharged, the air collecting cylinder 400 and the air outlet pipe 140 are refilled with water, returning to their initial state. This cycle repeats to agitate the water. At the same time, the motor 210 starts, which allows the air inlet pipe 120 to rotate and controls the rotation speed. The air inlet pipe 120 can drive the air outlet pipe 140 and the rotating block to rotate, so that multiple air outlet pipes 140 can rotate and aerate, which is conducive to comprehensive and uniform aeration, improves aeration efficiency, and allows sewage and air to mix thoroughly. This mechanism has a simple transmission method and simple structure, which meets people's growing demand for sewage treatment.
