Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a nitrous oxide production wastewater treatment pond. Background Technology

[0002] Nitrous oxide, a colorless gas with a sweet taste, also known as laughing gas, is an oxidant that can support combustion under certain conditions but is stable at room temperature. It has a mild anesthetic effect and is soluble in water, ethanol, ether, and concentrated sulfuric acid. It can also be used as an oxidant in rockets and racing cars, as well as to increase engine output power. Currently, the production of nitrous oxide requires the use of specialized wastewater treatment ponds to treat the wastewater generated.

[0003] However, most existing nitrous oxide production wastewater treatment ponds typically require the addition of chemicals to the treatment pond. These chemicals react with the wastewater to alter its physicochemical and biological properties. However, the lack of mixing function after adding chemicals results in a slow reaction between the chemicals and the wastewater, affecting the reaction efficiency. Furthermore, the inability to clean the filters in the treatment pond leads to clogging after long-term use, thus reducing the filtration performance of the filters.

[0004] Therefore, this utility model provides a nitrous oxide production wastewater treatment pond to solve the above problems. Utility Model Content

[0014] (III) Beneficial Effects

[0015] This invention, through the arrangement of a motor, a first rotating rod, a stirring blade, a transmission belt, a second rotating rod, sector teeth, teeth, guide blocks, and unclogging blocks, allows the treatment tank to function as a mixing device. When the motor drives the first rotating rod to rotate, the first rotating rod drives the stirring blade to rotate, thus mixing the wastewater and chemicals and accelerating the chemical reaction between them. The transmission belt, which works in conjunction with the first rotating rod, drives the second rotating rod to rotate. When the second rotating rod drives the sector teeth to rotate, the teeth meshing with the sector teeth drive the guide blocks to move back and forth. This causes the guide blocks, through a connecting plate, to drive multiple unclogging blocks to clean impurities from the first filter screen. Therefore, this device enables the treatment tank to have a mixing function, accelerating the chemical reaction between chemicals and wastewater, thereby improving the wastewater reaction efficiency. Furthermore, it cleans the first filter screen within the treatment tank, preventing clogging after long-term use and ensuring its filtration performance is maintained. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] This utility model provides a wastewater treatment pond for nitrous oxide production, such as... Figure 1-5 As shown, the sewage treatment tank includes a treatment tank body 1. A first filter screen 2 is fixedly connected inside the treatment tank body 1. A first rotating rod 3 is rotatably connected to the top of the treatment tank body 1. A motor 4 for driving the first rotating rod 3 to rotate is provided above the treatment tank body 1. A stirring blade 5 is fixedly connected to the outer surface of the first rotating rod 3. A second rotating rod 6 is rotatably connected to the top of the treatment tank body 1. A transmission belt 7 is connected between the second rotating rod 6 and the first rotating rod 3. A sector tooth 8 is fixedly connected to the outer surface of the second rotating rod 6. A connecting plate 9 is provided inside the treatment tank body 1. Multiple unblocking blocks 10 are fixedly connected to the outer wall of the connecting plate 9. A guide block 11 is fixedly connected to the top of the connecting plate 9. Multiple teeth 12 that mesh with the sector tooth 8 are fixedly connected to the inner wall of the guide block 11.

[0025] The motor 4 enables the first rotating rod 3 to rotate. When the motor 4 is running, the output shaft drives the first rotating rod 3 to rotate. As the first rotating rod 3 drives the stirring blade 5 to rotate, the sewage and the agent are stirred and mixed, accelerating the chemical reaction between the sewage and the agent. This achieves the purpose of changing the physicochemical and biological characteristics of the sewage. During the rotation of the first rotating rod 3, the transmission belt 7 drives the second rotating rod 6 to rotate synchronously. The second rotating rod 6 drives the sector tooth 8 to rotate. When the sector tooth 8 rotates, the multiple teeth 12 that mesh with it drive the guide block 11 to move back and forth. The guide block 11 drives the multiple unblocking blocks 10 to move back and forth through the connecting plate 9. During the back and forth movement, the unblocking blocks 10 can be inserted into the filter holes of the first filter screen 2 to clean the impurities mixed in with the first filter screen 2, ensuring that the filter holes of the first filter screen 2 remain unobstructed and preventing its filtration performance from being affected by clogging.

[0026] A telescopic rod 13 is fixedly connected to the outer wall of the guide block 11, and the end of the telescopic rod 13 away from the guide block 11 is fixedly connected to the inner wall of the treatment tank body 1.

[0027] The telescopic rod 13 provides a fixed point for the guide block 11, and the telescopic characteristics of the telescopic rod 13 allow the guide block 11 to move simultaneously, preventing the guide block 11 from falling due to lack of support. This ensures that the teeth 12 inside the guide block 11 can form a normal meshing state with the sector teeth 8, so that when the teeth 12 inside the guide block 11 are meshed by the rotation of the sector teeth 8, the guide block 11 has good stability when moving the connecting block, ensuring that the unblocking block 10 can clean the impurities mixed in the first filter screen 2.

[0028] The connecting plate 9 has multiple water passage holes 14 inside, and the inner cavity of the treatment tank body 1 is connected to the water inlet pipe 15.

[0029] The water passage 14 provides space for the flow of sewage in the connecting plate 9, preventing the flow of sewage from being blocked when the connecting plate 9 moves multiple unblocking blocks 10 close to the first filter screen 2, thus ensuring that sewage can still flow even when the unblocking blocks 10 are cleaning the first filter screen 2, and the water inlet pipe 15 enables the sewage to flow into the treatment tank body 1.

[0030] The inner cavity of the treatment tank body 1 is connected to an outlet pipe 16. A second filter screen 17 is installed inside the outlet pipe 16. A paddle 18 for squeezing the second filter screen 17 is rotatably connected inside the outlet pipe 16. A spring 19 is fixedly connected to the outer wall of the second filter screen 17. The end of the spring 19 away from the second filter screen 17 is fixedly connected to the inner wall of the outlet pipe 16. The inner cavity of the outlet pipe 16 is connected to a discharge port 20. A sealing plate 21 is installed inside the discharge port 20. The position of the discharge port 20 corresponds to that of the second filter screen 17.

[0031] The flow space provided by the outlet pipe 16 allows the filtered wastewater to flow into other treatment equipment for further processing. The second filter screen 17 provides a secondary filtration effect for the wastewater discharged through the outlet pipe 16, further improving its quality. The paddle 18 rotates upon impact with the wastewater, contacting and compressing the second filter screen 17. This compression, combined with the elastic force of the spring 19, causes the second filter screen 17 to vibrate, effectively cleaning impurities adhering to it. To prevent the second filter screen 17 from being clogged by impurities and affecting its filtration performance, the discharge port 20 provides space for impurities that fall off due to shaking to be discharged outward, preventing impurities from remaining in the water outlet pipe 16 and causing pollution. The sealing plate 21 allows the discharge port 20 to have the function of opening or sealing, preventing sewage in the water outlet pipe 16 from leaking through the discharge port 20 at the same time. Thus, the discharge port 20 can be opened according to the discharge requirements of impurities. In addition, a sealing layer is provided between the sealing plate 21 and the discharge port 20 to prevent sewage from still leaking from the discharge port 20.

[0032] Working principle:

[0033] When chemicals are added to the treatment tank body 1, the motor 4 is first started, causing the output shaft of the motor 4 to drive the first rotating rod 3 to rotate. The first rotating rod 3 drives the stirring blade 5 to rotate, which causes the stirring blade 5 to stir and mix the sewage and chemicals, thereby accelerating the chemical reaction between the sewage and chemicals. When the first rotating rod 3 rotates, the transmission belt 7, which is in drive with the first rotating rod 3, drives the second rotating rod 6 to rotate. When the second rotating rod 6 drives the fan-shaped teeth 8 to rotate, the multiple teeth 12 that mesh with the fan-shaped teeth 8 can drive the guide block 11 to move back and forth. When the guide block 11 drives the connecting plate 9 to move back and forth, the connecting plate 9 can drive multiple unblocking blocks 10 to repeatedly clean and unblock the impurities mixed in the first filter screen 2, so as to ensure the filtration performance of the first filter screen 2.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
