DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1: A water pollution treatment aeration device, such as Figure 1-Figure 5 As shown, it includes a sewage pool 1, the top of the sewage pool 1 is open, and an inlet valve 2 is fixedly connected to the upper part of one side of the sewage pool 1. The inlet valve 2 is used to introduce sewage into the sewage pool 1, and an outlet valve 3 is fixedly connected to the lower part of one side of the sewage pool 1. The inlet valve 2 and the outlet valve 3 are both connected to the sewage pool 1, and the outlet valve 3 is used to discharge the sewage in the sewage pool 1. Two shells 4 are fixedly connected to the sewage pool 1, and the two shells 4 are symmetrically arranged. One of the shells 4 is provided with an aeration mechanism, and the other shell 4 is provided with a rotating mechanism. The aeration mechanism is used to aerate the sewage in the sewage pool 1, and the rotating mechanism is used to change the outlet direction of the aeration mechanism.

[0022] The aeration mechanism includes an aeration pump 5, wherein a plurality of aeration pumps 5 are connected to one of the housings 4 by bolts, and the plurality of aeration pumps 5 are arranged at even intervals, and the outlet pipe of the aeration pump 5 passes through one of the housings 4. A plurality of groups of sealed bearings 6 are fixedly connected to the sewage pool 1, and the sealed bearings 6 are used to prevent the sewage in the sewage pool 1 from leaking. The plurality of groups of sealed bearings 6 are arranged at even intervals, and the number of sealed bearings 6 in each group is two. A hollow tube 7 is fixedly connected between the inner rings of the two sealed bearings 6 in the same group, and one end of each hollow tube 7 is rotatably connected to the outlet pipe of each aeration pump 5. A plurality of one-way valves 8 are fixedly connected to each hollow tube 7, and the one-way valve 8 is used to prevent the sewage from flowing back. The plurality of one-way valves 8 on the same hollow tube 7 are arranged at even intervals, and the one-way valve 8 is connected to the hollow tube 7. The aeration pump 5 introduces air into the sewage pool 1 through the hollow tube 7 and the one-way valve 8.

[0023] The rotating mechanism includes a motor 9, wherein a plurality of the motors 9 are connected to one of the housings 4 by bolts, and the plurality of motors 9 are arranged at even intervals. The output shaft of the motor 9 passes through one of the housings 4, and a gear 10 is fixedly connected to the output shaft of the motor 9. A gear 2 11 is fixedly connected to one end of the hollow tube 7, and the gear 10 is meshed with the gear 2 11. The motor 9 drives the gear 2 11 to rotate through the gear 10, thereby driving the hollow tube 7 to rotate.

[0024] Initially, the water inlet valve 2, the water outlet valve 3, the aeration pump 5 and the motor 9 are all in the closed state. The one-way valve 8 is used to discharge the gas in one direction and prevent water from flowing back into the hollow tube 7. After starting work, the staff opens the water inlet valve 2 and passes the sewage into the sewage pool 1. After the sewage pool 1 is full, the staff closes the water inlet valve 2 and stops passing the sewage. Then the staff starts the aeration pump 5. The aeration pump 5 inhales air and inputs the air into the hollow tube 7. After entering the hollow tube 7, the air is discharged upward through the one-way valve 8. The air enters the sewage to generate bubbles, and the bubbles burst to release oxygen, thereby increasing the oxygen content in the sewage and accelerating the decomposition reaction of aerobic microorganisms.

[0025] After the sewage is passed into the sewage pool 1, some large-volume substances in the sewage will settle down to form sediment. After aeration begins, the staff starts the motor 9, and the output shaft of the motor 9 rotates to drive the gear 10 to rotate, and the rotation of the gear 10 drives the gear 2 11 to rotate, and the rotation of the gear 2 11 drives the hollow tube 7 to rotate, and the rotation of the hollow tube 7 drives the one-way valve 8 to rotate. Through the above operation, it is convenient to adjust the direction of the gas outlet during aeration, so that the sediment at the bottom can also be aerated, making the sewage aeration more complete. Then the staff keeps the output shaft of the motor 9 rotating at a constant speed until the aeration time is reached. After the sewage aeration is completed, the staff turns off the aeration pump 5 and the motor 9, and then opens the water outlet valve 3 to discharge the sewage after the aeration. After the sewage is discharged, the staff closes the water outlet valve 3 to facilitate the next work.

[0026] Example 2: Based on Example 1, Figure 3-Figure 6 As shown, a turning mechanism is also included. The turning mechanism is provided at the lower part of the inner wall of the sewage tank 1. The turning mechanism is used to turn over the sediment at the bottom of the inner wall of the sewage tank 1. The turning mechanism includes a rotating shaft 12. The lower part of the inner wall of the sewage tank 1 is connected to a plurality of the rotating shafts 12 through bearings. The plurality of the rotating shafts 12 are evenly spaced. The rotating shaft 12 is located below the hollow tube 7. Each of the rotating shafts 12 is fixed with a plurality of turning frames 13. The plurality of the turning frames 13 on the same rotating shaft 12 are evenly spaced. A transmission component 14 is provided between the rotating shaft 12 and the hollow tube 7. The hollow tube 7 drives the rotating shaft 12 to rotate through the transmission component 14, thereby driving the plurality of the turning frames 13 to rotate.

[0027] The transmission assembly 14 includes a driving wheel, a driven wheel and a transmission belt. One end of the hollow tube 7 is fixedly connected to the driving wheel, and one end of the rotating shaft 12 is fixedly connected to the driven wheel. A transmission belt is wound between the driving wheel and the driven wheel. The hollow tube 7 drives the driven wheel to rotate through the driving wheel and the transmission belt, thereby driving the rotating shaft 12 to rotate.

[0028] The turning frame 13 is arranged in a curved manner, and the curved turning frame 13 is used to enable the turning frame 13 to turn over the sediments on the bottom of the pool more smoothly.

[0029] Initially, the rotating shaft 12 and the turning frame 13 are located at the bottom of the inner wall of the sewage tank 1. The sediment formed by the large volume of matter in the water will cover the rotating shaft 12 and the turning frame 13. During the aeration process, the hollow tube 7 rotates to drive the rotating shaft 12 to rotate through the transmission component 14. The rotation of the rotating shaft 12 drives several turning frames 13 to rotate. The turning frames 13 rotate to turn the sediment deposited at the bottom of the inner wall of the sewage tank 1. Through the above operation, the sediment can be aerated more completely, and the sewage can be further aerated completely.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
