Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to a sludge feeding device for wastewater treatment commissioning. Background Technology
[0002] Wastewater treatment plants (especially those using biological treatment processes such as activated sludge and biofilm processes) need to go through a "commissioning phase" before they can be put into operation. During this phase, the treatment system lacks sufficient microorganisms to degrade pollutants. Therefore, it is necessary to "inoculate" microorganisms by adding sludge externally. The role of the sludge dosing device is to precisely control the amount, concentration, and location of sludge addition, helping the system to quickly establish biological treatment capacity.
[0003] Traditional sludge feeding devices suffer from problems such as sludge clogging pipes and the inability to adjust the feeding direction, which not only affects the efficiency of sewage treatment but also increases operating costs and maintenance difficulty. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a sludge feeding device for sewage treatment commissioning, thereby solving the existing problems mentioned in the background art.

[0012] Beneficial effects
[0013] This utility model provides a sludge feeding device for wastewater treatment commissioning. It has the following beneficial effects:
[0014] (1) The sludge feeding device for sewage treatment commissioning, through the cooperation between the spiral blades, the air pump and the inclined nozzle, the rotation of the spiral blades not only pushes the sludge forward, but also further stirs and crushes it, which helps to prevent the sludge from clogging in the pipe. The air pump sends airflow into the sludge feeding shell through the conduit and the inclined nozzle to form an "air knife" effect, further cutting the high-concentration sludge and avoiding the occurrence of clogging problems. These designs make the sludge feeding device of this utility model have higher stability and durability in sewage treatment commissioning.
[0015] (2) The sludge feeding device used for sewage treatment commissioning can change the angle of the guide plate by adjusting the extension and retraction of the cylinder through the controller, thereby controlling the direction of sludge throwing. This design allows the sludge to be inclined to spread or to fall vertically, meeting the needs of different sewage treatment scenarios. For example, when it is necessary to uniformly cover the treatment area with sludge, the inclined spreading method can be selected, while when it is necessary to concentrate the treatment of a certain area with sludge, the vertical falling method can be selected.

[0023] like Figures 1-4 As shown, this utility model provides a sludge feeding device for sewage treatment commissioning, including a base 1. A support frame 2 and a support seat 3 are fixedly connected to the upper surface of the base 1. A sludge storage tank 4 is fixedly connected inside the support frame 2. A sludge feeding shell 12 is fixedly connected to the upper surface of the support seat 3. A third motor 13 is fixedly connected to the end of the sludge feeding shell 12. A third rotating shaft 14 is fixedly connected to the output end of the third motor 13. A spiral blade 15 is fixedly connected to the outer surface of the third rotating shaft 14. An air pump 16 is provided at the top of the sludge feeding shell 12. A conduit 17 is fixedly connected to the output end of the air pump 16. An inclined nozzle 18 is fixedly connected to the outer surface of the conduit 17. A discharge pipe 19 is fixedly connected to the side of the bottom of the sludge feeding shell 12. A flexible hose 20 is provided at the bottom end of the discharge pipe 19. A guide plate 21 is fixedly connected to the bottom end of the flexible hose 20. A support plate 22 is fixedly connected to the bottom of the sludge feeding shell 12. A cylinder 23 is provided on the outer surface of the support plate 22.
[0024] Specifically, the top of the sludge storage tank 4 is equipped with a first motor 5 and a feed hopper 24. The output end of the first motor 5 is fixedly connected to a first rotating shaft 6, and the outer surface of the first rotating shaft 6 is fixedly connected to a stirring rod 7.
[0025] Specifically, the outer surface of the first rotating shaft 6 penetrates the sludge storage tank 4 and extends into the inner cavity, and the stirring rod 7 is disposed in the inner cavity of the sludge storage tank 4.
[0026] Specifically, a second motor 8 is installed on the outer surface of the sludge storage tank 4, and a second rotating shaft 9 is fixedly connected to the output end of the second motor 8. A rotating plate valve 10 is fixedly connected to the outer surface of the second rotating shaft 9.
[0027] Specifically, the end of the second rotating shaft 9 away from the second motor 8 is rotatably connected to the inside of the sludge storage tank 4, and the rotating plate valve 10 is set in the inner cavity of the sludge storage tank 4. A sealing ring 11 is provided on the outer surface of the rotating plate valve 10.
[0028] Specifically, the bottom of the sludge storage tank 4 passes through the sludge feeding shell 12 and extends into the inner cavity. The conduit 17 and the inclined nozzle 18 are arranged in the inner cavity of the sludge feeding shell 12, and the inclined nozzle 18 is arranged above the spiral blade 15.
[0029] Specifically, the end of the cylinder 23 away from the support plate 22 is hinged to the outer surface of the guide plate 21.
[0030] The working principle and beneficial effects of the above embodiments.
[0031] In use, sludge enters the sludge storage tank 4 through the feed hopper 24. When the first motor 5 starts, the stirring rod 7 rotates inside the sludge storage tank 4 to fully stir the sludge, ensuring its uniformity and fluidity. When sludge needs to be added, the second motor 8 starts, and its output end drives the rotary valve 10 to rotate through the second rotating shaft 9. The opening degree of the rotary valve 10 can be adjusted by controlling the second motor 8, thereby realizing the quantitative addition of sludge. To ensure the sealing of the rotary valve 10, a sealing ring 11 is provided on its outer surface. The added sludge enters the sludge feeding shell 12 through the outlet at the bottom of the sludge storage tank 4. Inside the sludge feeding shell 12, the third motor 13 starts, and its output end drives the spiral blades 15 to rotate through the third rotating shaft 14. The rotation of the spiral blades 15 not only pushes... In addition to the forward movement of the sludge, it is further stirred and crushed. At the same time, the air pump 16 is started, which sends air into the sludge feeding shell 12 through the conduit 17 and the inclined nozzle 18. The airflow direction of the inclined nozzle 18 is at a 45° angle to the pushing direction of the spiral blade 15. The 45° inclined airflow forms an "air knife" effect in the gap of the spiral blade 15, cutting the high-concentration sludge and avoiding blockage. The axial component of the airflow is consistent with the mechanical propulsion direction of the spiral blade 15, which reduces the frictional resistance between the sludge and the pipe wall and improves the conveying efficiency. When the sludge is pushed to the end of the sludge feeding shell 12, the sludge is discharged through the discharge pipe 19. The controller adjusts the extension and retraction of the cylinder 23, changes the angle of the guide plate 21, and controls the direction of sludge throwing, so that the sludge can be inclined to spread or fall vertically.
