Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to a multi-stage wastewater sterilization device. Background Technology

[0002] Wastewater refers to water discharged from domestic and industrial processes that has been polluted to a certain extent. It mainly includes domestic sewage, industrial wastewater, and initial rainwater. The main pollutants in wastewater include pathogens, plant nutrients, etc., which can reduce or eliminate the usability of water.

[0003] In the process of wastewater treatment, the wastewater must first be filtered to remove particulate matter. However, the filtered water may still contain a large number of pathogenic microorganisms, such as bacteria and viruses, which are harmful to human health. Therefore, further treatment with a sterilization device is necessary. Existing wastewater sterilization devices use ultraviolet lamps to sterilize the wastewater. Since the wastewater flows under the ultraviolet lamps, sterilization is only temporary, resulting in poor effectiveness and inconvenience for users. Utility Model Content

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Example

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a multi-stage wastewater sterilization device includes a base plate 1 and two support frames 2 installed on top of the base plate 1. Multiple sterilization mechanisms are installed between the two support frames 2. Each sterilization mechanism includes an installation cylinder 3, an installation groove 8 formed on the top of the installation cylinder 3, an installation box 4 detachably installed inside the installation groove 8, and an ultraviolet lamp 7 installed inside the installation box 4. Fixing blocks 5 are installed at both ends of the installation cylinder 3, and the two sides of the fixing blocks 5 are respectively fixed to one side of the two support frames 2. A fixing cylinder 9 communicating with the installation cylinder 3 is installed on one side of the installation cylinder 3. A rotating rod 10 is rotatably connected to the inner wall of the fixing cylinder 9, and one end of the rotating rod 10 is rotatably connected to the inner wall of one side of the installation cylinder 3. Multiple impellers 11 are installed on the outside of the fixed cylinder 9, and multiple flip plates 12 are installed on the outside of the rotating rod 10, which are located inside the mounting cylinder 3. Each pair of adjacent sterilization mechanisms are arranged in opposite directions. A connecting pipe 29 is installed on the top of the fixed cylinder 9, and the top end of the connecting pipe 29 is connected to the mounting cylinder 3 above the connecting pipe 29. When sewage flows inside the mounting cylinder 3, the multiple impellers 11 installed on the outside of the rotating rod 10 will rotate. Driven by the multiple impellers 11, the rotating rod 10 will rotate. Driven by the rotating rod 10, the multiple flip plates 12 will rotate. The flip plates 12 will turn up the sewage inside the mounting cylinder 3, so that the ultraviolet lamp tube 7 can better sterilize the sewage.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a second fixing plate 25 is installed on one side of one of the support frames 2. A water pump 26 is installed at the bottom of the second fixing plate 25. The outlet of the water pump 26 is connected to the top fixing cylinder 9 through an outlet pipe. An inlet pipe is installed at the inlet of the water pump 26. A sewage detector 28 is installed on the top of the base plate 1. The inlet of the sewage detector 28 is connected to the bottom mounting cylinder 3 through an inlet pipe. An outlet pipe is installed at the outlet of the sewage detector 28. A connecting pipe 27 is installed between the outlet pipe and the water pipe. Valves are installed on the outside of both the outlet pipe and the connecting pipe 27. The sewage detector 28 is a COD detector, which is suitable for water quality testing of surface water, groundwater, industrial wastewater, domestic sewage, etc. It is a common detector in the prior art. The testing standards can be set according to the national sewage discharge standards.

[0026] It should be noted that in the operation of this multi-stage wastewater sterilization device, the water pump 26 draws the filtered wastewater into the outlet pipe through the inlet pipe. The water entering the outlet pipe flows into the top fixed cylinder 9. At this time, under the impact of the wastewater, multiple impellers 11 installed outside the rotating rod 10 rotate. Driven by the multiple impellers 11, the rotating rod 10 rotates. Driven by the rotating rod 10, multiple tilting plates 12 rotate, tilting the wastewater inside the mounting cylinder 3, thereby allowing the ultraviolet lamp tube 7 to better sterilize the wastewater. The wastewater entering the top mounting cylinder 3 enters the mounting cylinder 3 located below the top through the connecting pipe 29. According to the above operating principle, the wastewater can be further purified. Because the filtration system has multiple sterilization mechanisms, it can perform multi-stage sterilization of wastewater, improving the sterilization effect. After sterilization, the wastewater enters the wastewater detector 28, which detects the sterilized wastewater. When the sterilized wastewater meets the discharge standards, the valve installed outside the outlet pipe opens, and the valve installed outside the connecting pipe 27 closes, allowing the wastewater to be discharged through the outlet pipe. When the sterilized wastewater does not meet the discharge standards, the valve installed outside the outlet pipe closes, and the valve installed outside the connecting pipe 27 opens, allowing the sterilized wastewater to flow back into the outlet pipe through the connecting pipe 27, thus performing multi-stage sterilization again until the wastewater meets the discharge standards. Example

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, this embodiment is further improved on the basis of embodiment 1 in that: a sealing plate 22 is installed on the outside of the mounting box 4, a sealing groove 24 that cooperates with the sealing plate 22 is opened on the top of the mounting cylinder 3, a first fixing hole 21 is opened at each of the four corners of the sealing plate 22, and a plurality of second fixing holes 23 that cooperate with the first fixing holes 21 are opened in the sealing groove 24, and the corresponding first fixing holes 21 and second fixing holes 23 are connected by bolts 20; a fixing head 19 is installed at both ends of the ultraviolet lamp tube 7, and a fixing mechanism for fixing the ultraviolet lamp tube 7 is installed on both sides of the mounting box 4. The fixing mechanism includes a fixing head 19 installed in the mounting box 4. The upper sleeve 13, the sliding plate 15 slidably connected inside the sleeve 13, the spring 14 installed on one side of the sliding plate 15, and the movable plate 16 installed on the other side of the sliding plate 15. One end of the spring 14 is fixed to the inner wall of the sleeve 13. One side of the movable plate 16 extends to the outside of the sleeve 13 and is equipped with a first fixing plate 17. One side of the first fixing plate 17 is equipped with a limiting post 18 extending into the mounting box 4. The end of the limiting post 18 is provided with a fixing groove 30 that cooperates with the fixing head 19. One end of the ultraviolet lamp tube 7 is electrically connected to a wire. The inside of the fixing groove 30 is provided with a wire hole 31 that penetrates to one side of the first fixing plate 17. When replacing the UV lamp 7, the bolts can be unscrewed from the first fixing hole 21 and the second fixing hole 23. After removing all the bolts from the sealing plate 22, remove the sealing plate 22 from the sealing groove 24, and then pull the first fixing plate 17 away from the mounting box 4. At this time, the sliding plate 15 will slide inside the sleeve 13, and the spring 14 will undergo elastic deformation. Under the action of the first fixing plate 17, the limit post 18 will move. When the fixing head 19 separates from the fixing groove 30, the UV lamp 7 can be directly removed from the mounting box 4. When installing the UV lamp 7, first... The wire is threaded through the inside of one of the fixing slots 30 into the wire hole 31. At this time, the terminal of the wire hole 31 will be located outside the mounting box 4. The ultraviolet lamp 7 is placed between the two limiting posts 18. After the first fixing plate 17 is loosened, the fixing head 19 will be located in the fixing slot 30 under the action of the spring 14, thereby fixing the ultraviolet lamp 7. Then, the sealing plate 22 is placed in the sealing slot 22. At this time, the mounting box 4 will be located in the mounting slot 8. The bolt 20 is screwed back into the first fixing hole 21 and the second fixing hole 23 to fix the sealing plate 22 in the sealing slot 24, which facilitates the replacement of the damaged ultraviolet lamp 7.
