Technical Field

[0001] The utility model relates to the technical field of environmental protection engineering, in particular to a pretreatment device for vertical subsurface flow artificial wetlands. Background Art

[0002] Artificial wetlands are artificially constructed and controlled swamp-like land. They are a process system that uses the physical, chemical and biological effects of natural ecosystems to treat sewage and wastewater. As an ecological pollution control technology, artificial wetlands also have the disadvantages of large land area, heavy pollution load, and poor operation and management that can easily cause wetland pollution. In order to improve polluted artificial wetlands and improve treatment efficiency, they are often combined with traditional sewage treatment processes to treat sewage in artificial wetlands.

[0003] At present, when artificial wetland sewage is discharged after pretreatment, the residual pollutants in the sewage will be adsorbed on the wall of the sedimentation tank, making it difficult to discharge the pollutants. If the wall of the sedimentation tank is contaminated with residues, it may affect the sedimentation effect, making it difficult for suspended matter and impurities to settle, and causing unstable effluent water quality. For this reason, we provide a pretreatment device for vertical subsurface flow artificial wetlands to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0021] The present embodiment provides a pretreatment device for a vertical submerged flow artificial wetland, which is used to clean the side walls during its use. By setting the cooperation between the slide 2, the servo motor 3, the connecting shaft 4, the first bevel gear 5, the lifting mechanism 6 and the scraper ring 7, starting the servo motor 3 can drive the connecting shaft 4 and the first bevel gear 5 to rotate, and under the transmission of the lifting mechanism 6, the scraper ring 7 can be driven to move up and down on the inner wall of the treatment box 1, thereby cleaning the side walls of the treatment box 1 and completely discharging them, and the overall cleaning is convenient to avoid pollutants being adsorbed on the side walls and affecting the water quality.

[0022] See also Figure 1 to Figure 4 A pretreatment device for a vertical subsurface artificial wetland comprises a treatment box 1, both sides of which are provided with slide grooves 2, the upper surface of the treatment box 1 is fixedly connected to a servo motor 3, both ends of the servo motor 3 are fixedly connected to a connecting shaft 4, the ends of the two connecting shafts 4 away from each other are fixedly connected to a first bevel gear 5, and the outer surface of the treatment box 1 is provided with two symmetrical lifting mechanisms 6.

[0023] See also Figure 1 , Figure 4 The lifting mechanism 6 includes a fixed sleeve 601, the outer surface of the fixed sleeve 601 is fixedly connected to the outer surface of the processing box 1, and the inner wall of the fixed sleeve 601 is rotatably connected to the threaded tube 602. In this embodiment, the fixed sleeve 601 can support and guide the threaded tube 602 to ensure its rotation stability.

[0024] The upper surface of the threaded tube 602 is fixedly connected with a second bevel gear 603, and the second bevel gear 603 is meshed with the first bevel gear 5. The inner wall of the threaded tube 602 is threadedly connected with a threaded rod 604, and the bottom end of the threaded rod 604 is fixedly connected with a slider 605. The outer surface of the slider 605 is slidably connected to the inner wall of the slide groove 2. In this embodiment, the slider 605 cooperates with the slide groove 2 to limit and guide the threaded rod 604, thereby preventing the threaded rod 604 from rotating with the threaded tube 602, resulting in the inability to lift or lower.

[0025] The top of the threaded rod 604 is fixedly connected to a connecting plate 606, the bottom surface of the connecting plate 606 is fixedly connected to two connecting rods 607, and the outer surfaces of the connecting rods 607 are slidably connected to the inner wall of the processing box 1, and the ends of the two connecting rods 607 away from the bottom surface of the connecting plate 606 are fixedly connected to the outer surface of the scraper ring 7. In this embodiment, the connecting rod 607 can drive the scraper ring 7 to move up and down under the guidance of the threaded rod 604 and the connecting plate 606, thereby cleaning the inner wall of the processing box 1.

[0026] The inner wall of the treatment box 1 is slidably connected with a scraper ring 7. In the present embodiment, the scraper ring 7 has a special shape, wherein one side of the bottom is an inclined surface. Due to the inclined surface, the width of the bottom portion close to the treatment box 1 is extremely small, thereby efficiently scraping off the pollutants on the inner wall of the treatment box 1. A water inlet pipe 8 is fixedly installed on the outer surface of the treatment box 1.

[0027] The outer surface of the treatment box 1 is fixedly connected to a storage box 9, and the outer surface of the storage box 9 is rotatably connected to four circular arrays of cleaning doors 10. The outer surfaces of the four cleaning doors 10 are all fixedly connected to sealing gaskets. In this embodiment, the sealing gaskets on the surfaces of the cleaning doors 10 can prevent the sewage inside the storage box 9 from flowing out and leaking when the cleaning doors 10 are closed.

[0028] An annular filter plate 11 is fixedly connected to the inner wall of the storage box 9. In the present embodiment, the annular filter plate 11 can filter the impurities inside the storage box 9, and let the sewage flow into the bottom of the treatment box 1 through the connecting pipe 12 for discharge. The bottom surface of the storage box 9 is fixedly connected to the connecting pipe 12, and the inner wall of the connecting pipe 12 is connected to the inner wall of the storage box 9 and the inner wall of the treatment box 1.

[0029] The inner wall of the treatment box 1 is provided with four connecting grooves 16 in a circumferential array, and a conical filter plate 13 is fixedly connected to the inner wall of the treatment box 1. In the present embodiment, the conical filter plate 13 is in the shape of a pointed cone, so that when the conical filter plate 13 filters sewage, the inclined surfaces around it can introduce impurities into the interior of the storage box 9 for storage. The outer surface of the conical filter plate 13 is fixedly connected with a protective box 14, and the inner wall of the protective box 14 is fixedly connected with a vibrator 15. In the present embodiment, the protective box 14 can protect the vibrator 15 to prevent the vibrator 15 from being damaged. Thereafter, the vibration generated by the protective box 14 can be transmitted to the conical filter plate 13 through the vibrator 15, thereby accelerating the flow rate of impurities.

[0030] Working principle: When using this embodiment, first, starting the servo motor 3 can drive the connecting shaft 4 and the first bevel gear 5 to rotate. At this time, the first bevel gear 5 can drive the second bevel gear 603 to rotate, thereby driving the threaded tube 602 to rotate. After that, the rotation of the threaded tube 602 can drive the threaded rod 604 to move, and under the combined limit of the slider 605 and the slide groove 2, the threaded rod 604 can be driven to stably move up and down. Then, the movement of the threaded rod 604 drives the connecting plate 606 and the connecting rod 607 to move, thereby driving the scraper ring 7 to move on the inner wall of the processing box 1, thereby cleaning the inner wall of the processing box 1. Finally, the cleaned impurities are guided by the bottom of the processing box 1 to slide into the connecting groove 16 and enter the interior of the storage box 9 for storage. After being filtered by the annular filter plate 11, the sewage in the impurities can be discharged through the connecting pipe 12 into the bottom of the processing box 1, and the impurities stored in the storage box 9 are convenient for the staff to centrally clean them.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
