[0025] Reference Figures 1 to 6The present invention relates to an air-lift sludge discharge device, comprising: 1. an air-lift sludge discharge device, characterized in that it includes a main body 1, a cover plate 16 fixedly connected to the upper surface of the main body 1, a toothed ring 17 rotatably connected to the lower surface of the cover plate 16, a scraper 20 fixedly connected to the lower surface of the toothed ring 17, an inclined frame 21 fixedly connected to the lower surface of the scraper 20, a positioning ring 22 fixedly connected to the inner center of the inclined frame 21 near the main body 1, a limiting ring 18 fixedly connected to the upper surface of the toothed ring 17, a circular frame 24 fixedly connected to the lower surface of the cover plate 16, a connecting plate 15 fixedly connected to the lower surface of the main body 1, a motor 14 fixedly connected to the upper surface of the connecting plate 15, a drive gear 13 fixedly connected to the drive end of the motor 14, a through groove opened on the upper surface of the connecting plate 15, and a sewage treatment tank 19 fixedly connected to the surface of the through groove of the connecting plate 15. After the motor 14 starts, it drives the drive gear 13 to rotate. The drive gear 13 rotates under the drive of the motor 14. Since it meshes with the gear ring 17, it drives the gear ring 17 to rotate together, transmitting the rotational power of the motor 14 to the gear ring 17. When the gear ring 17 rotates, it drives the scraper 20 and the inclined frame 21 fixedly connected to it to rotate synchronously. Under the drive of the gear ring 17, the scraper 20 and the inclined frame 21 scrape off the sludge on the inner wall of the sewage treatment tank 19.

[0026] A flange ring is fixedly connected to the circular pipe surface of the connecting pipe 11 near the fixed plate 6. A flange ring is fixedly connected to the surface of the air outlet pipe of the air pump 5. The flange ring surface of the connecting pipe 11 is fixedly connected to the flange ring surface of the air pump 5. A plate groove 10 is opened on the lower surface of the cover plate 16. The surface of the plate groove 10 is rotatably connected to the limiting ring 18. The outer frame surface of the circular frame 24 away from the cover plate 16 is fixedly connected to the sewage treatment tank 19. The surface of the drive gear 13 meshes with the surface of the gear ring 17. A support rod 2 is fixedly connected to the lower surface of the connecting plate 15. The surface of the cover plate 16 is fixedly connected to the protective box 8. In the sludge discharge stage, the electrically controlled valve 4 and the electrically controlled dead valve 12 are first activated to form a communication channel between the connecting pipe 11 and the sludge discharge pipe 3. After the air pump 5 is started, the air pump 5 delivers high-pressure gas into the connecting pipe 11. The high-pressure gas enters the sludge discharge pipe 3 through the connecting pipe 11. Under the action of air pressure, the sludge that has been initially settled below the sludge discharge pipe 3 is forced into the sludge discharge pipe 3 and smoothly transported to the outside of the device. The flange rings on the connecting pipe 11 and the air outlet pipe of the air pump 5 are fixedly connected to each other, and a rubber sealing ring is provided on the surface between the two flange rings to ensure the sealed connection between the connecting pipe 11 and the air outlet pipe of the air pump 5. This ensures that high-pressure gas can be stably delivered from the air pump 5 to the connecting pipe 11, avoids gas leakage, and ensures the smooth progress of the air lifting and sludge discharge process.

[0027] A connecting rod 7 is fixedly connected to the upper surface of the connecting plate 15, a fixing plate 6 is fixedly connected to the upper surface of the connecting rod 7, an air pump 5 is provided on the upper surface of the fixing plate 6, a through groove is opened on the round pipe surface of the mud discharge pipe 3 near the air pump 5, a connecting pipe 11 is fixedly connected to the through groove surface of the mud discharge pipe 3, and an electric control valve 4 is provided on the round pipe surface of the connecting pipe 11.

[0028] A protective box 8 is fixedly connected to the upper surface of the connecting plate 15. The surface of the protective box 8 is fixedly connected to the main body 1. A connector 9 is fixedly connected to the upper surface of the cover plate 16. A mud discharge pipe 3 is rotatably connected to the inner surface of the positioning ring 22. A fixing ring 23 is fixedly connected to the circular tube surface of the mud discharge pipe 3 away from the positioning ring 22. The surface of the fixing ring 23 is fixedly connected to the connector 9. An electrically controlled dead valve 12 is provided on the circular tube surface of the mud discharge pipe 3.

[0029] Working principle: When sludge needs to be treated inside the sewage treatment tank 19, the motor 14 is started to drive the drive gear 13 to rotate. This drives the gear ring 17, which meshes with the drive gear 13, to rotate under the constraint of the limiting ring 18 and the plate groove 10 on the surface of the cover plate 16. The rotation of the gear ring 17 causes the scraper 20 to rotate accordingly. The inclined frame 21 follows the scraper 20 and rotates under the cooperation of the positioning ring 22, the sludge discharge pipe 3, and the conical inner wall below the sewage treatment tank 19. The rotation of the scraper 20 and the inclined frame 21 affects the sewage treatment tank 19. The stubborn sludge adhering to the inner wall falls off, the motor 14 stops driving the drive gear 13 to rotate, so that the scraper 20 and the inclined frame 21 stop rotating. After the water surface inside the sewage treatment tank 19 returns to calm, the electric control valve 4 and the electric control dead valve 12 are started to allow the connecting pipe 11 and the sludge discharge pipe 3 to flow. Then, the air pump 5 is started to deliver high-pressure gas into the connecting pipe 11, so that the sludge that has initially settled below the sludge discharge pipe 3 enters the sludge discharge pipe 3 under air pressure and is transported to the outside of the device, effectively improving the sludge treatment efficiency.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
