Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and in particular to an aerator with uniform aeration for sewage treatment. Background Art

[0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Aeration refers to increasing the contact area between water and air by filling water with air or mechanically stirring it. It is an intermediate process for aerobic biological treatment of wastewater. It not only makes the liquid in the pool contact with air for oxygenation, but also accelerates the transfer of oxygen in the air to the liquid due to the stirring of the liquid, thereby completing the purpose of oxygenation. The aerator is one of the important equipment in sewage treatment. The aerator injects microbubbles directly into the untreated sewage. Under the joint action of coagulants and flocculants, it promotes physical and chemical flocculation of suspended matter, so that impurities in the water form a large number of suspended flocs floating on the water surface.

[0003] In the prior art, the utility model with the authorization announcement number CN212954519U is named: A sewage treatment aerator. The patent drives the butterfly on the rotating shaft to rotate through a servo motor, so as to stir and aerate the sewage in the aeration tank. At the same time, the rotation of the butterfly drives the first bottom plate and the second bottom plate to move together, so as to fully stir the sewage in the aeration tank.

[0004] In the prior art, the utility model with the authorization announcement number CN219469836U is named: an aerator for sewage treatment. The patent sets a stirring assembly, first starts the micro waterproof motor to drive the stirring blade to rotate, and then starts the servo motor. When the servo motor rotates forward, the threaded block drives the connecting plate to move up, so that the stirring blade moves up. When the servo motor rotates reversely, it can be seen from the above that the stirring blade moves down, that is, the stirring blade rotates and moves up and down reciprocatingly, which can stir the bubbles generated by the aeration fan, increase the contact area of ​​the remaining sewage, and achieve the purpose of high sewage treatment efficiency.

However, the aeration pipe on the aerator itself does not have the ability to stir the sewage, resulting in uneven diffusion of bubbles generated by aeration, affecting the effect of sewage treatment. For this reason, we propose an aerator with uniform aeration for sewage treatment. Utility Model Content

[0026] A mixing mechanism 2 for aerating sewage is disposed inside the sewage treatment tank 1 . The mixing mechanism 2 includes an aerator body 201 and two connecting pipes 202 . The aerator body 201 is fixedly connected to the sewage treatment tank 1 .

[0027] The aerator body 201 is installed on one side of the sewage treatment tank 1. The aerator body 201 can adopt the jet aerator in the prior art, which is composed of five parts: a submersible pump, an ejector, a diffuser, an air suction pipe and a hose. It integrates advanced diffuser technology on the basis of traditional jet mechanism and adopts jet aeration method to produce small and numerous bubbles with high dissolved oxygen rate, which can improve the sewage treatment effect.

[0028] The two connecting pipes 202 are both rotatably connected to the sewage treatment tank 1. The outer surfaces of the two connecting pipes 202 are connected to a plurality of aeration pipes 203. The outer surfaces of the two connecting pipes 202 are both provided with first sealed bearings 204. The inner walls of the two first sealed bearings 204 are both provided with rotating rods 205. The outer surfaces of the connecting pipes 202 and the rotating rods 205 are both fixedly connected to the inner rings of the first sealed bearings 204. The two rotating rods 205 are both rotatably connected to the sewage treatment tank 1.

[0029] The connecting pipe 202 and the aeration pipe 203 are both hollow structures. The connecting pipe 202 and the rotating rod 205 can both rotate in the inner wall of the sewage treatment tank 1. The connecting pipe 202 is connected to the rotating rod 205 through the first sealing bearing 204, and the first sealing bearing 204 is used to seal the connection between the two.

[0030] After the rotating rod 205 rotates, it can drive the inner ring of the first sealed bearing 204 to rotate, thereby driving the connecting pipe 202 fixedly connected to the inner ring of the first sealed bearing 204 to rotate, and then driving the aeration pipe 203 to rotate, thereby achieving the stirring of the sewage. The aeration pipes 203 fixed on the two connecting pipes 202 are cross-arranged, which can further improve the effect of sewage stirring.

[0035] The output end of the aerator body 201 is connected to a three-way pipe 206, and the two first sealed bearings 204 are both connected to the three-way pipe 206.

[0036] Example 2

[0037] like Figure 1 to Figure 4 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes that one side of the sewage treatment tank 1 is connected to a liquid inlet pipe 7, and a control valve is installed on the outer surface of the liquid inlet pipe 7.

[0039] Furthermore, a filter screen may be provided at the connection between the inlet pipe 7 and the discharge pipe 8 and the sewage treatment tank 1 to prevent flocs formed during sewage treatment from clogging the inlet pipe 7 and the discharge pipe 8, thereby ensuring the normal use of the inlet pipe 7 and the discharge pipe 8.

[0040] A control panel 10 is installed on the front of the sewage treatment tank 1, the aerator body 201 is electrically connected to the control panel 10, and the servo motor 4 is electrically connected to the control panel 10.

[0043] The components in the drawings of the present invention are only for style reference and are not used as specific size standards. The specific sizes are determined according to the actual requirements of production.

[0044] Working principle: When using the aerator to treat sewage, the aerator body 201 is connected to the municipal power supply and started. The aerator body 201 can blow pressurized air into the three-way pipe 206, so that the pressurized air enters the connecting pipe 202 through the reserved hole on the first sealed bearing 204, until it is sprayed out from the reserved hole on the aeration pipe 203, so that the oxygen in the air enters the sewage in the sewage treatment tank 1 and reacts chemically with the sewage, thereby achieving the purpose of decontamination of the sewage. At the same time, the servo motor 4 is connected to the municipal power supply and started. The servo motor 4 can drive the first gear 5 to rotate, and the first gear 5 is meshed with the two second gears 6. The two second gears 6 are driven to rotate in the opposite direction, and then the two rotating rods 205 are driven to rotate in the opposite direction. Since the outer surfaces of the rotating rod 205 and the connecting pipe 202 are fixed to the inner ring of the first sealing bearing 204, the two connecting pipes 202 can be driven to rotate in the opposite direction, and then the aeration pipes 203 thereon are driven to rotate, so that the sewage is stirred during aeration. The aeration pipes 203 fixed on the two connecting pipes 202 are cross-arranged, which can further improve the sewage stirring effect, make the bubbles generated by aeration diffuse outward more evenly, increase the contact area between the bubbles and the remaining sewage, and achieve the purpose of improving the sewage treatment effect.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
