Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment, and in particular to a municipal sewage treatment device. Background Technology

[0002] Municipal wastewater treatment involves purifying wastewater—a source of water with highly variable quality that is extremely difficult to treat—to meet the water quality requirements for discharge into a specific water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, healthcare, and catering, and is increasingly becoming a part of everyday life for ordinary people. During wastewater treatment, chemical reagents can be added to alter the properties of the wastewater, making it harmless to the environment and water bodies.

[0003] Existing wastewater treatment devices include treatment tanks and stirring components. Wastewater is placed into the treatment tank, and chemical reagents are added to the wastewater. Then, the stirring component stirs the wastewater to accelerate the mixing of wastewater and chemical reagents, thereby accelerating the reaction efficiency. The stirring component includes a rotating column with multiple blades distributed on its surface. The rotating column drives the multiple blades to stir the wastewater. However, this stirring method has a low agitation effect on the wastewater, resulting in a slow mixing efficiency between wastewater and reagents, which increases the wastewater treatment time.

[0004] Therefore, it is necessary to provide a new municipal wastewater treatment device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a municipal sewage treatment device.

[0006] This utility model provides a municipal sewage treatment device including a treatment tank. The treatment tank is equipped with a stirring assembly for stirring the sewage. The top of the stirring assembly extends through the top of the inner wall of the treatment tank. A support plate is provided on the top of the stirring assembly. A driving component is installed on the top of the support plate. The output end of the driving component is fixedly connected to the top of the stirring assembly. Lifting components are respectively connected to both ends of the bottom of the support plate. One side of each of the two lifting components is fixedly connected to the outer wall of the treatment tank. A reagent box is fixedly installed on the top of the treatment tank.

[0007] Preferably, the stirring assembly includes a lifting column, which is hollow and located inside the processing tank. The top of the lifting column penetrates the top of the inner wall of the processing tank and is fixedly connected to the bottom of the support plate. A first bevel gear is fixedly provided at the bottom of the lifting column. A rotating column is provided inside the lifting column. The top of the rotating column penetrates the bottom of the support plate and is fixedly connected to the output end of the drive component. One side of the drive component is fixedly connected to the top of the support plate. A plurality of rotating rods are provided on the surface of the rotating column. One end of each of the plurality of rotating rods is rotatably connected to the surface of the rotating column. A blade is provided at the end of each of the plurality of rotating rods away from the rotating column. A plurality of through holes are provided on the surface of each of the plurality of rotating rods. A second bevel gear is fixedly provided on the surface of each of the plurality of rotating rods. The plurality of second bevel gears mesh with the first bevel gear.

[0008] Preferably, the driving component is a servo motor, one side of which is fixedly connected to the top of the support plate by multiple bolts, and the output end of the servo motor is fixedly connected to the top of the rotating column.

[0009] Preferably, the lifting component includes a first fixed block, a second fixed block, and an electric telescopic rod. One side of the first fixed block and the second fixed block are respectively fixedly connected to the bottom and top of the outer wall of the processing tank. The bottom end of the electric telescopic rod is fixedly connected to the top of the first fixed block, and the output end of the electric telescopic rod movably passes through the bottom end of the second fixed block and is fixedly connected to the bottom of the support plate.

[0010] Preferably, the bottom end of the lifting column is provided with a protective shell, which is rotatably connected to the surface of the lifting column and rotatably connected to the surface of the rotating rod.

[0011] Preferably, a scraper ring is movably sleeved on the surface of the lifting column, and the top of the hanging ring is fixedly connected to the top of the treatment tank.

[0012] Preferably, a limiting ring is fixedly sleeved on the surface of the rotating column, and the bottom of the limiting ring is in contact with the top of the lifting column.

[0013] Compared with related technologies, the municipal sewage treatment device provided by this utility model has the following beneficial effects:

[0014] By activating the drive unit, the rotating column is driven to rotate. Since the second bevel gear meshes with the first gear, when the rotating column rotates, the second bevel gear will roll on the surface of the first bevel gear, thereby causing the rotating rod itself to rotate. The rotation of the rotating rod will drive the blades to rotate, so that the blades rotate around the lifting column while the blades themselves also rotate. This not only stirs the sewage but also improves the tumbling effect of the sewage. The above structure can accelerate the fusion efficiency between sewage and reagents and shorten the sewage treatment time to a certain extent. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figures 1-6 ,in, Figure 1 A schematic diagram of the overall structure of a municipal sewage treatment device provided by this utility model; Figure 2 for Figure 1 The diagram shows the internal structure of the processing tank 1. Figure 3 A cross-sectional structural schematic diagram of a municipal sewage treatment device provided by this utility model; Figure 4 for Figure 2 The diagram shows the overall structure of the stirring assembly. Figure 5 for Figure 4 A schematic diagram of the enlarged structure of A shown; Figure 6 for Figure 4 The diagram shows the disassembled structure of the stirring assembly.

[0024] In the specific implementation process, such as Figures 1-6As shown, a municipal wastewater treatment device includes a treatment tank 1. Inside the treatment tank 1, there is a stirring assembly for stirring the wastewater. The top of the stirring assembly extends through the top of the inner wall of the treatment tank 1. A support plate 2 is provided on the top of the stirring assembly. A driving component is installed on the top of the support plate 2 to drive the stirring assembly to rotate. Lifting components are connected to both ends of the bottom of the support plate 2 to drive the support plate 2 to rise and fall. One side of each of the two lifting components is fixedly connected to the outer wall of the treatment tank 1. A reagent box 3 is fixedly installed on the top of the treatment tank 1. The reagent box 3 is used to add reagents to the wastewater. A control panel is provided on the reagent box 3. Chemical reagents are placed in the reagent box 3, and the amount of chemical reagents added to the wastewater can be controlled through the control panel.

[0025] The mixing assembly includes a lifting column 4, which is hollow and located inside the treatment tank 1. The top of the lifting column 4 penetrates the top of the inner wall of the treatment tank 1 and is fixedly connected to the bottom of the support plate 2. A first bevel gear 5 is fixedly installed at the bottom of the lifting column 4. A rotating column 6 is installed inside the lifting column 4. The top of the rotating column 6 penetrates the bottom of the support plate 2 and is fixedly connected to the output end of the drive component. One side of the drive component is fixedly connected to the top of the support plate 2. Multiple rotating rods 7 are provided on the surface of the rotating column 6. One end of each of the multiple rotating rods 7 is rotatably connected to the surface of the rotating column 6. Blades 16 are respectively provided at the ends of the multiple rotating rods 7 away from the rotating column 6. Multiple through holes are provided on the surface of the blades 16 to reduce the resistance of the wastewater to the blades 16. Multiple rotating rods 7 are respectively fixed with second bevel gears 8, and multiple second bevel gears 8 mesh with first bevel gears 5. The driving component is a servo motor 9. One side of the servo motor 9 is fixedly connected to the top of the bearing plate 2 by multiple bolts. The output end of the servo motor 9 is fixedly connected to the top of the rotating column 6. By starting the servo motor 9, the rotating column 6 is driven to rotate. Since the second bevel gears 8 mesh with the first gear, when the rotating column 6 rotates, the second bevel gears 8 will roll on the surface of the first bevel gear 5, thereby causing the rotating rods 7 to rotate. The rotation of the rotating rods 7 will drive the blades 16 to rotate, so that the blades 16 rotate around the lifting column 4 while the blades 16 themselves also rotate.

[0026] The lifting component includes a first fixed block 10, a second fixed block 11, and an electric telescopic rod 12. One side of the first fixed block 10 and the second fixed block 11 are fixedly connected to the bottom and top of the outer wall of the processing tank 1, respectively. The bottom end of the electric telescopic rod 12 is fixedly connected to the top of the first fixed block 10. The output end of the electric telescopic rod 12 moves through the bottom end of the second fixed block 11 and is fixedly connected to the bottom of the support plate 2. When the electric telescopic rod 12 is activated, the output end of the electric telescopic rod 12 drives the support plate 2 to continuously lift and lower.

[0027] The bottom end of the lifting column 4 is provided with a protective shell 13, which is rotatably connected to the surface of the lifting column 4 and rotatably connected to the surface of the rotating rod 7. It is used to protect the first bevel gear 5 and multiple second bevel gears 8 to prevent solids in the sewage from getting stuck between the first bevel gear 5 and the second bevel gears 8.

[0028] A scraper ring 14 is movably fitted on the surface of the lifting column 4. The top of the ring is fixedly connected to the top of the treatment tank 1. The scraper ring 14 is used to scrape off the sewage attached to the surface of the lifting column 4 to prevent the lifting column 4 from carrying the sewage out of the treatment tank 1 when it rises.

[0029] A limiting ring 15 is fixedly sleeved on the surface of the rotating column 6. The bottom of the limiting ring 15 is in contact with the top of the lifting column 4. The limiting ring 15 is used to limit the rotation of the rotating column 6.

[0030] The working principle of this utility model is as follows: Sewage is placed into the treatment tank 1, and then the chemicals in the chemical tank are added into the sewage. By starting the servo motor 9, the rotating column 6 is driven to rotate. Since the second bevel gear 8 meshes with the first gear, when the rotating column 6 rotates, the second bevel gear 8 will roll on the surface of the first bevel gear 5, thereby causing the rotating rod 7 to rotate. The rotation of the rotating rod 7 will drive the blades 16 to rotate, so that the blades 16 rotate around the lifting column 4 and the blades 16 themselves will also rotate, which will not only stir the sewage but also improve the tumbling effect of the sewage. By starting the electric telescopic rod 12, the output end of the electric telescopic rod 12 drives the bearing plate 2 to continuously lift and lower, so that multiple blades 16 can lift and lower in the sewage, and the blades 16 can stir the sewage at various depths.

[0031] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
