Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides an embodiment of a sewage treatment aeration device, including a treatment tank 1 and a main frame 2. The main frame 2 is fixedly installed at the top of the treatment tank 1, and a top frame 12 is fixedly installed at the top of the main frame 2. An installation box 11 is vertically fixed at the top of the top frame 12. A fixing seat 19 is provided at the bottom of the treatment tank 1, and an aeration main pipe 17 is horizontally fixed at both ends of the bottom of the fixing seat 19. A support rod 20 is vertically fixed at the top of the fixing seat 19, and guide rods are vertically fixed at both ends of the top of the fixing seat 19. The top of the mounting box 11 is fixed with a mounting cover 24. The top of the mounting box 11 is movably connected with a threaded sleeve 26, and a driven gear 25 is fixed to the outside of the threaded sleeve 26. A servo motor 27 is fixed to the right side of the top of the mounting cover 24, and the output shaft of the servo motor 27 passes through the inside of the top of the mounting cover 24 and is fixed with a drive gear 28. A lead screw 22 is threaded inside the threaded sleeve 26. Sliding sleeves 23 are fixed to both ends of the top of the top of the top frame 12. A controller 32 is fixed to the right side of the main frame 2.

[0021] The top end of the support rod 20 passes through the interior of the top end of the top frame 12. The bottom end of the lead screw 22 is movably connected to the top end of the support rod 20. The driving gear 28 and the driven gear 25 are meshed. The top end of the lead screw 22 passes through the interior of the top end of the mounting cover 24 and fixes the limit plate. The sliding sleeve 23 passes through the interior of the top end of the top frame 12. The top end of the guide rod 21 passes through the interior of the sliding sleeve 23.

[0022] Furthermore, the controller 32 is a PLC controller, and the servo motor 27 is electrically connected to the controller 32. The electrical connection relationship and control method between them are known technologies, so they will not be described in detail.

[0023] Specifically, such as Figures 1-3 As shown, when the aeration device is installed and used, the servo motor 27 can be controlled to start and drive the drive gear 28 to rotate. When the drive gear 28 rotates, the driven gear 25 can drive the threaded sleeve 26 to rotate. When the threaded sleeve 26 rotates, it can drive the internally threaded screw 22 to move upward, and at the same time drive the support rod 20 to move upward, moving the aeration main pipe 17 from the bottom end to the top inside the treatment tank 1. This allows for convenient maintenance and repair of the aeration components, and also allows for adjustment of the aeration height of the aeration components.

[0024] A blower 10 is fixedly installed on the left side of the top of the main frame 2, and an air supply pipe 9 is fixedly installed at the output end of the blower 10. A valve 8 is fixedly installed on the left side of the air supply pipe 9, and a hose 7 is fixedly installed on the left side of the valve 8. The bottom end of the hose 7 is fixedly connected to the left side of the front aeration main pipe 17. A blower 2 13 is fixedly installed on the right side of the top of the main frame 2, and an air supply pipe 2 14 is fixedly installed at the output end of the blower 2 13. A valve 2 15 is fixedly installed on the right side of the air supply pipe 2 14, and a hose 2 16 is fixedly installed on the right side of the valve 2 15. The bottom end of the hose 2 16 is fixedly connected to the right side of the rear aeration main pipe 17. Several air outlet pipes 18 are fixedly fixed at the bottom end of the aeration main pipe 17. Two sets of connecting pipes 31 are fixedly fixed between the two sets of aeration main pipes 17.

[0025] Furthermore, blower 10 and blower 2 13 are electrically connected to controller 32 respectively. The electrical connection relationship and control method between them are known technologies, so they will not be described in detail.

[0026] Specifically, such as Figure 1 As shown, when the aeration device is in use, the blower 10 can be started to deliver air to the aeration main pipe 17 through the air supply pipe 9 and the hose 7. The two sets of aeration main pipes 17 are connected by the connecting pipe 31, and the air can be introduced into the sewage through several air outlet pipes 18 at the bottom. During aeration operation, the amount of air entering the aeration main pipe 17 can be increased by simultaneously turning on the blower 13 on the right side, thereby increasing the aeration intensity. The aeration intensity of the device is adjustable.

[0027] A top cover 3 is fixed to the top of the main frame 2. Top covers 6 are respectively provided on both sides of the top of the top cover 3. The top covers 6 are symmetrically arranged about the vertical center line of the top cover 3. Connecting feet 5 are fixed to the two ends of the left side of the top cover 6. Two sets of connecting frames 4 are fixed to the top of the two sides of the top cover 3, respectively. The connecting feet 5 are hinged to the inside of the connecting frames 4. Locking rods 30 are respectively provided on the two ends of the right side of the top of the top cover 6. Two sets of connecting holes 29 are respectively provided on the left and right sides of the top of the top of the top cover 3. The bottom end of the locking rod 30 passes through the inside of the top cover 6 and is threaded into the connecting hole 29. A handle is fixed to the right side of the top of the top of the top cover 6.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, by installing a top cover 3 and a top cover 6 on the top of the device, the gas supply part can be provided with auxiliary outer cover protection, while the flip-up top cover 6 can expose the gas supply component and perform quick maintenance operations on it.

[0029] Working Principle: When the aeration device is installed at the top of the treatment tank 1, the blower 10 can be started to deliver air to the aeration main pipe 17 via the air supply pipe 9 and the hose 7. The two sets of aeration main pipes 17 are connected by the connecting pipe 31, and air can be introduced into the sewage through several air outlet pipes 18 at the bottom. During aeration operation, the air volume entering the aeration main pipe 17 can be increased by simultaneously turning on the right blower 13, thereby increasing the aeration intensity. When the aeration device is in use, the servo motor 27 can be started to drive the drive gear 28 to rotate. The rotation of the drive gear 28, along with the meshing driven gear 25, drives the threaded sleeve 26 to rotate. The rotation of the threaded sleeve 26 simultaneously drives the internally threaded screw 22 to move upward, and at the same time, it drives the support rod 20 to move upward, moving the aeration main pipe 17 from the bottom to the top of the treatment tank 1. This allows for convenient maintenance and repair of the aeration components, and also allows for adjustment of the aeration height of the aeration components. In addition, when the aeration device is in use, the top cover 3 and the top cover 6 installed on the top of the device can provide auxiliary outer cover protection for the air source supply.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
