[0002] At present, with the development of urbanization in China and the improvement of rural living standards, the rural living environment has been paid more and more attention. Untreated rural domestic sewage is an important factor affecting the rural living environment. The scattered distribution of farmers' houses according to geographical conditions has caused the scattered discharge of rural domestic sewage, making it difficult to collect. If centralized collection and treatment are carried out, it will greatly increase the pipeline network investment cost. Therefore, small integrated sewage treatment equipment is needed for the treatment of rural domestic sewage.

[0003] At present, in order to improve the efficiency of sewage treatment, integrated sewage treatment equipment on the market usually sets an aeration device inside.

[0004] However, due to the fixed position of the aeration holes of the existing aeration device, sundries in the sewage often adhere to and block the aeration holes during use, which easily causes a decrease in aeration efficiency and affects the efficiency of sewage treatment. Summary of the Utility Model

[0005] The integrated aeration-driven reflux sewage treatment device provided by the utility model aims to solve the problem that due to the fixed position of the aeration holes of the existing aeration device, sundries in the sewage often adhere to and block the aeration holes during use, which easily causes a decrease in aeration efficiency and affects the efficiency of sewage treatment.

A second partition is arranged between the aeration box and the sedimentation box; a sliding component is arranged at the top of the aerator, and the sliding component includes an aerator cover and a connecting cylinder. The connecting cylinder is movably connected with the aerator through the aerator cover. The connecting cylinder is connected with the aerator cover, and the aerator cover is located above the aerator, which is beneficial to automatically cover the surface of the aerator, reduce the cleaning efficiency of the aerator, and prevent the aerator from being blocked.

[0008] In a preferred embodiment, the sliding assembly further includes a bracket, a fixing frame and a spring. The spring is connected to the aerator through the bracket. The fixing frame is located above the spring and is connected to the side wall of the centralized treatment box body. The connection between the fixing frame and the spring is beneficial to improving the stability of the movement of the aerator cover.

[0009] In a preferred embodiment, a mixing shaft is rotatably arranged in the inner cavity of the mixing box. One end of the mixing shaft passes through the centralized treatment box body and is provided with a motor, and is connected to the output end of the motor.

[0022] Embodiment

[0023] Referring to the attached specification Figures 1-5 , an integrated aeration-driven reflux type sewage treatment device includes a centralized treatment box body 1, a mixing box 5, an aeration box 6, a sedimentation tank 7 and a box cover 2. The mixing box 5, the aeration box 6 and the sedimentation tank 7 are arranged in the inner cavity of the centralized treatment box body 1. The box cover 2 is arranged on the centralized treatment box body 1. A first partition plate 8 is arranged between the mixing box 5 and the aeration box 6. A first water inlet pipe 3 is arranged at the top of the mixing box 5. The first water inlet pipe 3 is located on the surface of the box cover 2. A plurality of aerators 61 are arranged at the bottom of the aeration box 6. The aerators 61 are used to increase the oxygen inside the aeration box 6. A second partition plate 9 is arranged between the aeration box 6 and the sedimentation tank 7;

[0024] A sliding assembly is arranged at the top of the aerator 61. The sliding assembly includes an aerator cover 62 and a connecting cylinder 622. The connecting cylinder 622 is movably connected with the aerator 61 through the aerator cover 62. The connecting cylinder 622 is connected with the aerator cover 62. The aerator cover 62 is located above the aerator 61.

[0025] It should be noted that the aerators 61 are interconnected through air pipes, and the air pipes are connected to a blower. When the aerator 61 is in a stationary state, the aerator cover 62 covers the top of the aerator 61. When the aerator 61 discharges air, the blower blows air into the air pipe, so that oxygen is ejected into the aeration tank 6 through the aerator 61 to increase the oxygen content inside the aeration tank 6. When the aerator 61 continuously blows air outwards, when the air pressure between the aerator 61 and the aerator cover 62 reaches a certain level, the air pressure will blow up the aerator cover 62, making the aerator cover 62 float above the aerator 61. When the aerator 61 stops working, the aerator cover 62 slowly descends due to the loss of the air pressure power ejected by the aerator 61. When the connecting cylinder 622 contacts the aerator 61, due to the automatic descent of the aerator cover 62, a certain negative pressure is generated between the contact surfaces of the aerator cover 62 and the aerator 61, causing the sundries and liquid between the aerator 61 and the aerator cover 62 to be automatically discharged due to the flowing property of the liquid, so that the aerator 61 and the connecting cylinder 622 are automatically adsorbed, covering the air holes on the surface of the aerator 61, which can effectively prevent the aerator 61 from being blocked and reduce the frequency of cleaning the aerator 61.

[0026] Furthermore, the sliding assembly further includes a bracket 621, a fixing frame 611 and a spring 612. The spring 612 is connected to the aerator 61 through the bracket 621. The fixing frame 611 is located above the spring 612 and is connected to the side wall of the centralized treatment box body 1. The fixing frame 611 is connected to the spring 612.

[0027] In the above embodiment, the aerator covers 62 are interconnected through the bracket 621. Since the aerator cover 62 is in a suspended state during the operation of the aerator 61 due to pressure, the spring 612 is compressed under extrusion. After the aerator 61 stops working, the spring 612 pushes the aerator cover 62 to move through its own elasticity, improving the stability of the movement of the aerator cover 62.

[0028] Furthermore, a mixing shaft 41 is rotatably arranged in the inner cavity of the mixing box 5. One end of the mixing shaft 41 passes through the centralized treatment box body 1 and is provided with a motor 4, and is connected to the output end of the motor 4. A first through hole 81 is opened at a position of the first partition 8 close to the mixing shaft 41.

[0029] In the above embodiment, the motor 4 is used to drive the mixing shaft 41 to rotate, so that the water body is fully mixed, improving the aeration efficiency of the sewage.

[0030] Furthermore, a second through hole 91 is opened at a position on the upper surface of the second partition 9, and a third through hole 92 is opened at the bottom of the second through hole 91. The third through hole 92 is located at a lower position of the second partition 9.

[0031] In the above embodiment, a solenoid valve is disposed inside the third through hole 92 for controlling the return of the sludge precipitated in the inner cavity of the sedimentation tank 7 to the inner cavity of the aeration tank 6 to prevent excessive sludge in the inner cavity of the sedimentation tank 7. The second through hole 91 is used to introduce the mixed liquid into the inner cavity of the sedimentation tank 7.

[0032] Furthermore, an inclined surface table 71 is disposed inside the sedimentation tank 7. The top of the inclined surface table 71 is connected to an inclined filter baffle 73. One end of the inclined filter baffle 73 is connected to the side wall of the second partition plate 9. A plurality of intercepting filter plates 72 are disposed on the surface of the inclined filter baffle 73.

[0033] It should be noted that the precipitated sludge is concentrated and piled up at the opening of the third through hole 92 by the inclined surface table 71, and in cooperation with the inclined filter baffle 73, when the mixed sewage enters the inner cavity of the sedimentation tank 7, the sludge precipitated on the surface of the inclined surface table 71 is intercepted to prevent it from rolling up and down due to contact with the mixed sewage, which affects the sedimentation efficiency. At the same time, the mixed sewage is intercepted layer by layer by the intercepting filter plates 72, reducing the space where the sludge can roll, so that the sludge slowly precipitates into the storage cavity formed between the inclined filter baffle 73 and the inclined surface table 71, improving the sedimentation efficiency.

[0034] Furthermore, a second water inlet pipe 23 is disposed at the top of the sedimentation tank 7. The second water inlet pipe 23 is connected to the tank cover 2. A water pump 21 is disposed on the surface of the tank cover 2. The input end of the water pump 21 is connected to the second water inlet pipe 23, and the output end of the water pump 21 is connected to a water outlet pipe 22.

[0035] It should be noted that the water that can be discharged from the sedimentation tank 7 can be discharged through the water outlet pipe 22 by using the water pump 21.

[0036] In this embodiment, the implementation scenario is specifically as follows: Sewage is discharged into the inner cavity of the mixing tank 5 through 3, and the motor 4 drives the mixing shaft 41 to rotate to fully mix the sewage. At the same time, it flows into the aeration tank 6. When the blower blows air into the air pipe, oxygen is ejected into the aeration tank 6 through the aerator 61 to achieve oxygenation inside the aeration tank 6 for aeration. When the mixed sewage enters the inner cavity of the sedimentation tank 7 through the second through-hole 91, sedimentation separation is carried out; when the discharge standard is reached, the water inside the sedimentation tank 7 is discharged through the water outlet pipe 22 by the water pump 21; when the air pressure between the aerator 61 and the aerator cover 62 reaches a certain level, the aerator cover 62 will separate from the aerator 61, causing the aerator cover 62 to float above the aerator 61. When the aerator 61 stops working, the aerator cover 62 slowly descends due to the loss of the air pressure power ejected by the aerator 61. When the connecting cylinder 622 contacts the aerator 61, due to the automatic descent of the aerator cover 62, a certain negative pressure is generated between the contact surfaces of the aerator cover 62 and the aerator 61, causing the sundries and liquid between the aerator 61 and the aerator cover 62 to be automatically displaced due to the flowing property of the liquid, so that the aerator 61 and the connecting cylinder 622 are automatically adsorbed, covering the air holes on the surface of the aerator 61, which can effectively prevent the aerator 61 from being blocked and reduce the frequency of cleaning the aerator 61.

[0037] Finally, the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
