Description

Technical Field

[0001] This utility model relates to the field of ammonia nitrogen electrolysis treatment technology, specifically to an ammonia nitrogen electrolysis treatment device for biochemical wastewater. Background Technology

[0002] The fertilizer, chemical, pharmaceutical and waste treatment industries generate a large amount of ammonia nitrogen wastewater. The ammonia nitrogen content in the wastewater is very high, and direct discharge will cause great pollution to the environment. It is necessary to remove the ammonia nitrogen by electrolysis. However, the existing ammonia nitrogen electrolysis treatment equipment has certain defects in use. During the use of the existing ammonia nitrogen electrolysis treatment equipment, dirt will adhere to the outside of the cathode component. The dirt will affect the electrolysis effect of the cathode. Moreover, after the dirt forms, it needs to be cleaned manually, which affects the electrolysis effect of the existing equipment.

[0003] Patent publication number CN105283423B discloses an electrolysis mechanism that deploys at least one fixed cathode cleaning component to contact a surface of a rotating cathode. The electrolysis system is operated to cause the rotating cathode to rotate during an electrolysis process. As the rotating cathode rotates, the fixed cathode cleaning component removes scale accumulated on it. While the aforementioned patent addresses the problems mentioned above, the electrolysis mechanism in this patent still suffers from the following issues: during operation, the cathode and anode need to be energized to achieve the electrolysis process. However, during this process, impurities within the wastewater can affect the balance of the current within the wastewater. Consequently, ammonia nitrogen near the cathode and anode is removed, while the ammonia nitrogen content remains high in the wastewater further away, resulting in uneven ammonia nitrogen distribution. Furthermore, since only the cathode cleaning component moves within the device, the electrolysis effect is often low.

[0004] To address the aforementioned issues, innovative design based on the existing device structure is urgently needed. Utility Model Content

[0005] The purpose of this invention is to provide a biochemical wastewater ammonia nitrogen electrolysis treatment device to solve the problem mentioned in the background art that during the process of energizing the cathode and anode, the presence of impurities in the wastewater affects the balance of the current inside the wastewater. In this case, ammonia nitrogen in the wastewater near the cathode and anode is removed, while the ammonia nitrogen content in the wastewater far from the cathode and anode remains high, resulting in uneven distribution of ammonia nitrogen inside the wastewater. Furthermore, since only the cathode cleaning mechanism moves inside the device, it is easy to cause the electrolysis effect of the mechanism to be low.

[0027] 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.

[0028] In a specific embodiment, such as Figures 1-6 The diagram illustrates the basic operation of the device. The device body 1 includes a drain pipe 2 fixedly installed on its outer side. An inlet pipe 3 is fixedly installed on the upper outer side of the device body 1. A controller 4 is fixedly installed on the outer side of the device body 1. An acid frame 6 and an alkaline frame 7 are fitted onto the upper end of the device body 1. A pH detector 5 is fixedly installed at the lower end of the device body 1. A metering device 8 is fixedly installed at the lower ends of the acid frame 6 and the alkaline frame 7. A conductive component 9 is fixedly installed on the outer side of the device body 1. An anode assembly 10 and a cathode assembly 11 are fixedly installed at the end of the conductive component 9 closest to the device body 1, and the anode assembly 10 and the cathode assembly 11 are located inside the device body 1. Insulating blocks 13 are fixedly installed at both the upper and lower ends of the cathode assembly 11. The cathode assembly 11 is positioned on the outer side of the upper insulating block 13, and a mounting base plate 12 is positioned on the outer side of the lower insulating block 13. The mounting base plate 12 is fixedly installed inside the lower end of the device body 1.

[0029] When using this biochemical wastewater ammonia nitrogen electrolysis treatment device, wastewater containing a large amount of ammonia nitrogen needs to be discharged into the device through the inlet pipe 3. After the wastewater is added, the ammonia nitrogen in the wastewater can be removed. During this process, the anode assembly 10 and the cathode assembly 11 need to be energized through the conductive component 9. At this time, the ammonia nitrogen in the wastewater can be electrolyzed and removed. During this process, the pH index of the wastewater will change, and the change in pH value will affect the separation effect of ammonia nitrogen. At this time, the pH detector 5 will detect the change in pH value in the wastewater and transmit the signal to the controller 4. The controller 4 will control the metering device 8 to work, so that the acid and alkaline liquids inside the acid frame 6 and the alkaline frame 7 are discharged, and the pH value of the wastewater is adjusted to ensure the pH stability of the wastewater, thereby ensuring the effect of ammonia nitrogen removal from the wastewater.

[0030] In one specific embodiment, such as Figures 1-4 and Figures 6-7As shown, the process of descaling the cathode assembly 11 by the device is disclosed; a fixing rod 14 is fixedly installed inside the main body 1 of the device, and a cleaning plate 15 is slidably installed on the outer side of the fixing rod 14, and the outer side of the cleaning plate 15 is in close contact with the outer side of the cathode assembly 11; an mounting rod 16 is fixedly installed on the upper end of the cleaning plate 15, and an electric push rod 17 is fixedly installed on the upper end of the mounting rod 16, and a positioning plate 24 is fixedly installed on the upper end of the electric push rod 17, while the positioning plate 24 is fixedly installed on the upper outer side of the main body 1 of the device.

[0031] When using this biochemical wastewater ammonia nitrogen electrolysis treatment device, dirt will adhere to the outside of the cathode assembly 11. The adhesion of dirt will affect the electrolysis effect of the cathode assembly 11, so it is necessary to remove the dirt to ensure the electrolysis effect of the cathode assembly 11. During the process, the electric push rod 17 needs to move. The movement of the electric push rod 17 will drive the mounting rod 16 to move up and down. During the up and down movement of the mounting rod 16, the cleaning plate 15 will move up and down synchronously. The cleaning plate 15 is in close contact with the cathode assembly 11, which will effectively remove the dirt adhering to the outside of the cathode assembly 11, thereby exposing the cathode assembly 11 and ensuring the electrolysis effect of the device, thus ensuring the effect of the device in removing ammonia nitrogen.

[0032] Based on the above embodiments, such as Figures 1-4 and Figures 6-7 As shown, the automatic stirring effect of the device on wastewater is disclosed; a flip plate 18 is rotatably installed on the outer side of the cleaning plate 15, and a rotating rod 19 is rotatably installed inside the flip plate 18. The rotating rod 19 is slidably installed on the outer side of one end of the rotating rod 19 near the cleaning plate 15, and the end of the rotating rod 19 near the cleaning plate 15 is rotatably connected to the cleaning plate 15; a support spring 21 is provided inside the rotating rod 19, and the support spring 21 is fixedly connected to the adjusting rod 20. Two sets of adjusting rod 20 and rotating rod 19 are provided inside the flip plate 18; an upper inclined block 22 and a lower inclined block 23 are fixedly installed inside the main body 1 of the device, and two sets of upper inclined blocks 22 and lower inclined blocks 23 are provided inside the main body 1 of the device. The width of the upper inclined blocks 22 and lower inclined blocks 23 is greater than the distance between the cleaning plate 15 and the main body 1 of the device.

[0033] When using this biochemical wastewater ammonia nitrogen electrolysis treatment device, the cleaning plate 15 moves up and down on the outside of the fixed rod 14. During this movement, the cleaning plate 15 drives the tilting plate 18 to move. The tilting plate 18 agitates the wastewater inside the main body 1, causing it to flow and ensuring a balanced distribution of ammonia nitrogen, thus maintaining a balanced pH level. During this movement, the tilting plate 18 contacts the upper inclined block 22 and the lower inclined block 23. As the tilting plate 18 moves upwards, it contacts the upper inclined block 22, causing it to be squeezed and reversed. During this process, the adjusting rod 20 and the rotating... Rod 19 will rotate, and adjusting rod 20 will slide inwards towards the rotating rod 19. At this time, the supporting spring 21 will be compressed and contracted. During this process, the flipping plate 18 will rotate from the cleaning plate 15 to the lower end of the cleaning plate 15. Similarly, as the cleaning plate 15 drives the flipping plate 18 to move downwards, after the flipping plate 18 contacts the lower inclined block 23, it will rotate from the lower end of the cleaning plate 15 to the upper end of the cleaning plate 15. Through the internal rotation of the flipping plate 18, the flipping plate 18 can fully stir the wastewater, facilitate the flow of the wastewater, ensure the pH balance of the wastewater, and thus ensure the effect of electrolytic removal of ammonia nitrogen in the wastewater, increasing the overall practicality.
