[0002] Aerators are commonly used equipment in wastewater treatment. In the prior art, such as the aeration tank disclosed in Chinese patent application number 201821485592.0, the relationship between aerators and aeration tanks and the working principle of aerators are explained.

[0003] The aerators are designed to spray wastewater mixed with gas into the aeration tank through wastewater inlets. These wastewater inlets are connected to the aerators within the aeration tank and are used to effectively disperse the gas-containing wastewater into the aeration tank.

[0004] To improve wastewater treatment efficiency, aeration tanks typically employ a multi-loop design. However, with multiple wastewater inlets installed in the aeration tank, the water flows from different inlets may interfere with each other and gradually stabilize into a single confluence. This stable confluence then leads to the generation of eddies within the aeration tank.

[0005] In a vortex, water flows in a rotating manner, and at the center of the vortex, impurities in the wastewater will sink to the bottom of the aeration tank with the vortex.

[0006] The bottom of the aeration tank also has a sewage inlet. These impurities may be directly deposited at this sewage inlet by the eddy current, which may cause blockage of the sewage inlet, affecting the normal operation of the aerator and the sewage treatment efficiency.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. It should also be noted that the terminology used in this utility model is for describing specific implementations only and is not intended to limit the exemplary implementations according to this application.

[0022] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Therefore, the detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without inventive effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] The aeration device provided in Embodiment 1 of this utility model can reduce the deposition of impurities at the wastewater inlet, such as... Figures 1 to 4As shown, the aerator includes an aerator body 1, an eddy current sensor 2 that can detect eddies in water, and a control board 3. The aerator body 1 includes multiple sewage inlet nozzles 11 and a nozzle moving mechanism 12. The sewage inlet nozzles 11 are fixed on the nozzle moving mechanism 12. The nozzle moving mechanism 12 can drive the sewage inlet nozzles 11 to change the spray direction. The eddy current sensor 2 is electrically connected to the control board 3. The nozzle moving mechanism 12 is electrically connected to the control board 3.

[0025] The aeration device provided in Embodiment 1 of this utility model, which reduces the deposition of impurities at the wastewater inlet, is an assembly device installed in an aeration tank. The aerator is existing technology. In existing aerators, the aerator body 1 generates high-pressure wastewater mixed with gas, which is then sprayed into the aeration tank through the wastewater inlet nozzle 11. The difference between this embodiment and the existing technology is that the device in this embodiment has an eddy current sensor 2 (i.e., an eddy current flow sensor, which is existing technology and will not be described in detail here). This sensor can continuously monitor whether eddies occur in the aeration tank during the aeration process. If eddies occur, the signal generating the eddy current is transmitted to the control board 3, which then controls the nozzle movement mechanism 12 in the reverse direction. Changing the nozzle orientation of the sewage inlet nozzle 11 disturbs the already stable confluence in the aeration tank, thereby disrupting the conditions for the formation of the vortex and destroying the vortex. After the spray position of the sewage inlet nozzle 11 changes for a period of time, the water flow in the aeration tank will stabilize into a confluence again. If a vortex is generated at this time, it can be detected by the vortex sensor 2 and the nozzle orientation of the sewage inlet nozzle 11 will be changed again through the nozzle moving mechanism 12 to destroy the vortex. The purpose of destroying the vortex is to prevent the sewage from accumulating impurities at the bottom of the vortex center due to the existence of a vortex, thereby avoiding the rapid accumulation of impurities near the bottom of the sewage inlet nozzle 11 near the bottom of the vortex center, which could lead to blockage.

[0026] The aeration device provided in Embodiment 1 of this utility model can reduce the deposition of impurities at the sewage inlet, which solves the problem of easy deposition of impurities at the sewage inlet of the existing aerator, leading to blockage, and can reduce the deposition rate of impurities at the sewage inlet of the aerator.

[0027] To specifically achieve the adjustment of the spray direction of the sewage inlet nozzle 11, as a preferred embodiment, the aerator body 1 further includes a drain pipe 13; the drain pipe 13 is provided with multiple drain pipe outlets; the sewage inlet nozzle 11 includes a corrugated pipe 111 and a nozzle 112; each drain pipe outlet 131 is connected to a corrugated pipe 111; the inlet of the corrugated pipe 111 is connected to the drain pipe outlet; the inlet of the nozzle 112 is connected to the outlet of the corrugated pipe 111. The corrugated pipe 111 is existing technology. The corrugated pipe 111 allows the nozzle 112 to maintain communication with the drain pipe 13, and through its own characteristics, in conjunction with the nozzle moving mechanism 12, the spray direction of the nozzle 112 can be changed.

[0028] Since the nozzles 112 located at the bottom of the aeration tank are upward-facing, to prevent impurities from falling directly downwards into the nozzle outlet 112, in this embodiment, the wastewater inlet nozzle 11 also includes a conical baffle 113; the conical tip of the conical baffle 113 is upward-facing; the conical baffle 113 is fixed vertically above the nozzle 112. The conical baffle 113 prevents the nozzle outlet 112 from being directly exposed, and some large impurities will preferentially collide with the conical baffle 113, preventing large impurities from falling directly and damaging the nozzle 112, thus ensuring the normal operation of the lead-wire aeration.

[0029] To specifically realize the nozzle moving mechanism 12 driving the nozzle 112 to change the spray direction, in this embodiment, the nozzle moving mechanism 12 includes a drive assembly 121 and several rockers 122; the rockers 122 extend horizontally; the drive assembly 121 can drive the rockers 122 to move horizontally; several limiting holes 1221 are provided on the rockers 122; the bellows 111 passes through the limiting holes 1221 and is fixed; when the rockers 122 move horizontally, the inner wall of the limiting holes 1221 can touch and drive the bellows 111 to move. In this embodiment, the moving mechanism 12 drives the rockers 122 to rock, and the contact between the limiting holes 1221 on the rockers 122 and the bellows 111 causes the bellows 111 to adjust its posture, thereby changing the position of the nozzle 112 fixed on the bellows 111, and thus adjusting the spray direction.

[0030] To specifically realize the movement of the rocker arm 122 driven by the drive assembly 121, in this embodiment, the drive assembly 121 includes a first rotating rod 1211, a second rotating rod 1212, and a push rod 1213; the first rotating rod 1211 and the second rotating rod 1212 are rotatably fixed; the rotation axes of the first rotating rod 1211 and the second rotating rod 1212 are vertical; a plurality of rocker arms 122 are fixed on both the first rotating rod 1211 and the second rotating rod 1212; the extension directions of the first rotating rod 1211 and the second rotating rod 1212 form an obtuse angle; the push rod 1213 is rotatably fixed on the first rotating rod 1211; the push rod 1213 can push the first rotating rod 1211 to rotate relative to the second rotating rod 1212. The second rotating rod 1212 needs to be rotatably fixed inside the aeration tank with a vertical rotation axis. When the push rod 1213 moves along the extension direction of the push rod 1213, the positions of the two points—the fixed point between the first transmission rod 1211 and the push rod 1213, and the fixed point between the second rotating rod 1212 and the aeration tank—change, thereby adjusting the angle between the first rotating rod 1211 and the second rotating rod 1212. This changes the position of the rocker arm 122 fixed on the first rotating rod 1211 and the second rotating rod 1212, thereby changing the position of the limiting hole 1221. This causes the limiting block 1221 to push the bellows 111, thereby changing the spray direction of the nozzle 112 fixed on the bellows 111.

[0031] In summary, this utility model discloses an aeration device that can reduce the deposition of impurities at the wastewater inlet, relating to the field of wastewater treatment. It includes an aerator body, an eddy current sensor capable of detecting eddies in water, and a control board. The aerator body includes multiple wastewater inlet nozzles and a nozzle moving mechanism. The wastewater inlet nozzles are fixed to the nozzle moving mechanism. The nozzle moving mechanism can drive the wastewater inlet nozzles to change their spray direction. The eddy current sensor is electrically connected to the control board. The nozzle moving mechanism is also electrically connected to the control board. This utility model provides an aeration device that reduces the deposition of impurities at the wastewater inlet, solving the problem of easy blockage caused by impurities depositing at the wastewater inlet of existing aerators, and can reduce the deposition rate of impurities at the wastewater inlet of the aerator.
