Description

Technical Field

[0001] This utility model relates to the field of disinfection device technology, and in particular to a combined ultraviolet persulfate disinfection device for medical wastewater. Background Technology

[0002] Disinfection devices are equipment or systems specifically designed to kill or remove pathogenic microorganisms and their metabolic products in media such as liquids, gases, and solid surfaces. The medical wastewater UV-persulfate combined disinfection device is a water treatment device that integrates UV photocatalysis and persulfate advanced oxidation technology, and is specifically designed for the disinfection of medical wastewater.

[0003] Because existing UV persulfate combined disinfection devices lack cleaning devices for UV lamps, UV lamps working underwater for extended periods are prone to accumulating scale in wastewater. The scale on the lamp tube surface can cause UV light to scatter, thus affecting the disinfection effect. This may result in some microorganisms not being effectively killed, increasing the risk of microbial contamination after wastewater treatment. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing ultraviolet persulfate disinfection device lacks the ultraviolet lamp cleaning function, which leads to the accumulation of scale in the lamp tube during long-term underwater operation, affecting the dispersion of ultraviolet light and reducing the disinfection effect. To address this, we propose a combined ultraviolet persulfate disinfection device for medical wastewater.

[0005] To achieve the above objectives, this application adopts the following technical solution: a medical wastewater ultraviolet persulfate combined disinfection device, comprising a disinfection box, an ultraviolet lamp holder installed inside the disinfection box, a snap-fit ​​bracket fixedly connected to both sides of the ultraviolet lamp holder, the top of the disinfection box snapping into the bottom of the snap-fit ​​bracket, three sets of ultraviolet lamp tubes installed inside the ultraviolet lamp holder, four first sliding grooves opened at the top of the ultraviolet lamp holder, a first sliding block slidably connected inside the first sliding groove, a cleaning plate installed at the bottom of the first sliding block, a cleaning brush installed on one side of each cleaning plate, a square groove opened at the top of the first sliding block, a limit block slidably connected to both sides of the square groove, a limit groove opened on both sides of the first sliding groove, the surface of the limit block slidably connected to the inside of the limit groove, a round rod fixedly connected inside the square groove, and the inside of the limit block slidably connected to the surface of the round rod.

[0006] Preferably, a second sliding groove is provided on both sides of the first sliding groove, and a second slider is fixedly connected to both sides of the first sliding block, with the surface of the second slider slidably connected to the inside of the second sliding groove.

[0007] Preferably, a square plate is fixedly connected inside the square groove, and two first springs are fixedly connected to both sides of the square plate, with the other end of the first springs fixedly connected to the limiting block.

[0008] Preferably, a first circular groove is fixedly formed at one end of the first sliding groove, a second spring is fixedly connected inside the first circular groove, and the other end of the second spring is fixedly connected to the first sliding block.

[0009] Preferably, a second circular groove is provided on both sides of the cleaning plate, a third spring is fixedly connected inside the second circular groove, and a connecting block is fixedly connected to the other end of the third spring. A connecting groove is provided on both sides of the first sliding block, and the surface of the connecting block is slidably connected to the inside of the connecting groove.

[0010] Preferably, both ends of the bottom of the first sliding block are fixedly connected with snap-fit ​​blocks, and both ends of the top of the cleaning plate are provided with snap-fit ​​grooves, and the snap-fit ​​blocks and snap-fit ​​grooves are snapped together.

[0011] Preferably, a limiting plate is fixedly connected to the surface of the connecting block, and the surface of the limiting plate is slidably connected to the interior of the second circular groove.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, a first sliding block, a cleaning plate, and a cleaning brush are installed at the bottom of the ultraviolet lamp holder. Cleaning brushes are installed on both sides of the two cleaning plates located in the middle. Pressing the limiting block causes it to disengage from the limiting groove, releasing the first sliding block from its limiting position. This allows the first sliding block to move, driving the cleaning plates and cleaning brushes to clean the surface of the ultraviolet lamp. After cleaning, the first sliding block is reset, returning the limiting block to its limiting groove, thus restoring the limiting position. This design allows for rapid cleaning of the ultraviolet lamp surface, maintaining its cleanliness and ensuring that ultraviolet light is fully emitted and its intensity remains within an effective range, thereby guaranteeing the disinfection effect.

[0014] In this invention, by pressing the connecting block, the connecting block is disengaged from the inside of the connecting groove. At this time, the connection between the cleaning plate and the first sliding block is released. This setting allows for the maintenance of the cleaning plate and the cleaning brush connected to it, ensuring that each cleaning of the ultraviolet lamp achieves good results.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] Reference Figure 1 - Figure 5As shown, this utility model provides a technical solution: a medical wastewater ultraviolet persulfate combined disinfection device, including a disinfection box 1, an ultraviolet lamp holder 2 installed inside the disinfection box 1, and a snap-fit ​​bracket 3 fixedly connected to both sides of the ultraviolet lamp holder 2. The top of the disinfection box 1 is snapped to the bottom of the snap-fit ​​bracket 3. Three sets of ultraviolet lamp tubes 4 are installed inside the ultraviolet lamp holder 2. Four first sliding grooves 5 are opened at the top of the ultraviolet lamp holder 2. First sliding blocks 6 are slidably connected inside the first sliding grooves 5. Cleaning plates 7 are installed at the bottom of the first sliding blocks 6. Cleaning brushes 8 are installed on one side of each cleaning plate 7. A square groove 9 is opened at the top of the first sliding block 6. Limiting blocks 10 are slidably connected to both sides of the square groove 9. Limiting grooves 11 are opened on both sides of the first sliding groove 5. The surface of the limiting block 10 is slidably connected to the inside of the limiting groove 11. A round rod 12 is fixedly connected inside the square groove 9. The inside of the limiting block 10 is slidably connected to the surface of the round rod 12. The bottom of the UV lamp holder 2 is equipped with a first sliding block 6, a cleaning plate 7, and a cleaning brush 8. Cleaning brushes 8 are installed on both sides of the two cleaning plates 7 located in the middle. The surface of the cleaning brush 8 has a semi-circular groove that matches the curvature of the UV lamp tube surface, allowing it to cover the surface of the UV lamp for thorough cleaning. Pressing the limiting block 10 causes it to disengage from the limiting groove 11, releasing the first sliding block 6 from its limiting position. This allows the first sliding block 6 to move, driving the cleaning plate 7 and cleaning brush 8 to clean the surface of the UV lamp tube 4. After cleaning, the first sliding block 6 is reset, returning the limiting block 10 to the limiting groove 11, thus restoring the first sliding block 6 to its limiting position. This design allows for rapid cleaning of the UV lamp tube 4 surface, maintaining its cleanliness and ensuring that UV rays are fully emitted, reacting better with persulfate and guaranteeing effective disinfection.

[0024] Reference Figure 4 , Figure 5 and Figure 6 As shown in this embodiment: a second sliding groove 13 is provided on both sides of the first sliding groove 5, and a second slider 14 is fixedly connected to both sides of the first sliding block 6. The surface of the second slider 14 is slidably connected to the inside of the second sliding groove 13. By making the second slider 14 slide inside the second sliding groove 13, the movement of the first sliding block 6 can be made more stable, and unnecessary shaking and displacement of the first sliding block 6 during movement can be avoided.

[0025] Reference Figure 4As shown in this embodiment: a square plate 15 is fixedly connected inside the square groove 9. Two first springs 16 are fixedly connected to both sides of the square plate 15. The other end of the first spring 16 is fixedly connected to the limiting block 10. By setting the first spring 16, the elasticity of the first spring 16 abuts against the limiting block 10. When the user releases the press of the limiting block 10, the elasticity of the first spring 16 will automatically abut against the limiting block 10 to reset, so that the limiting block 10 enters the interior of the limiting groove 11, simplifying the operation process.

[0026] Reference Figure 5 and Figure 6 As shown in this embodiment: a first circular groove 17 is fixedly opened at one end of the first sliding groove 5, and a second spring 18 is fixedly connected inside the first circular groove 17. The other end of the second spring 18 is fixedly connected to the first sliding block 6. By setting the second spring 18, when the user releases the movement of the first sliding block 6, the elasticity of the second spring 18 will automatically pull the first sliding block 6 to reset, without the user having to manually reset it, thus providing convenience for the user.

[0027] Reference Figure 5 As shown in this embodiment: A second circular groove 19 is provided on both sides of the cleaning plate 7. A third spring 20 is fixedly connected inside the second circular groove 19. A connecting block 21 is fixedly connected to the other end of the third spring 20. A connecting groove 22 is provided on both sides of the first sliding block 6. The surface of the connecting block 21 is slidably connected to the inside of the connecting groove 22. By pressing the connecting block 21, the connecting block 21 is disengaged from the inside of the connecting groove 22. At this time, the connection between the cleaning plate 7 and the first sliding block 6 is released. Through this setting, the cleaning plate 7 and the cleaning brush 8 connected to it can be maintained, ensuring that each cleaning of the ultraviolet lamp 4 achieves good results.

[0028] Reference Figure 4 and Figure 5 As shown in this embodiment: both ends of the bottom of the first sliding block 6 are fixedly connected with snap-fit ​​blocks 23, and both ends of the top of the cleaning plate 7 are provided with snap-fit ​​grooves 24. The snap-fit ​​blocks 23 and the snap-fit ​​grooves 24 snap into each other. By snapping the snap-fit ​​grooves 24 into the snap-fit ​​blocks 23, the bottom of the cleaning plate 7 with the first sliding block 6 can be made more stable, and the shaking caused by the water flow can be avoided.

[0029] Reference Figure 5 As shown in this embodiment: the surface of the connecting block 21 is fixedly connected to the limiting plate 25, and the surface of the limiting plate 25 is slidably connected to the inside of the second circular groove 19. By setting the limiting plate 25, the movement position of the connecting block 21 can be restricted, preventing the connecting block 21 from coming out of the inside of the second circular groove 19 due to the elasticity of the third spring 20, thus ensuring the stability of the connection between the first sliding block 6 and the cleaning plate 7.

[0030] Working principle: A first sliding block 6, a cleaning plate 7, and a cleaning brush 8 are set at the bottom of the ultraviolet lamp holder 2. Cleaning brushes 8 are installed on both sides of the two cleaning plates 7 located in the middle. The surface of the cleaning brush 8 has a semi-circular groove that matches the curvature of the ultraviolet lamp tube surface, allowing it to cover the surface of the ultraviolet lamp for thorough cleaning. Pressing the limiting block 10 causes it to disengage from the limiting groove 11, releasing the limiting position of the first sliding block 6. This allows the first sliding block 6 to move, causing it to move the cleaning plate 7 and the cleaning brush 8, thus cleaning the surface of the ultraviolet lamp tube 4. The surface is cleaned, and after cleaning, the first sliding block 6 is reset, allowing the limiting block 10 to return to the inside of the limiting groove 11, thus restoring the first sliding block 6 to its limiting position. This setting allows for rapid cleaning of the surface of the ultraviolet lamp tube 4, keeping the lamp tube surface clean and ensuring that ultraviolet rays are fully emitted and their intensity remains within the effective range, thereby guaranteeing the disinfection effect. By allowing the second slider 14 to slide inside the second sliding groove 13, the movement of the first sliding block 6 is made more stable, avoiding unnecessary shaking and displacement of the first sliding block 6 during movement. This is achieved by setting the first spring. 16. The elasticity of the first spring 16 abuts against the limiting block 10. When the user releases the pressure on the limiting block 10, the elasticity of the first spring 16 will automatically abut against the limiting block 10 to reset, allowing the limiting block 10 to enter the limiting groove 11, simplifying the operation process. By setting the second spring 18, when the user releases the movement of the first sliding block 6, the elasticity of the second spring 18 will automatically pull the first sliding block 6 to reset, eliminating the need for manual reset by the user and providing convenience. By pressing the connecting block 21, the connecting block 21 is disengaged from the inside of the connecting groove 22. At this time, the cleaning plate 7 and the first The connection between the sliding blocks 6 is released. This setting allows for the maintenance of the cleaning plate 7 and the cleaning brush 8 connected to it, ensuring that each cleaning of the ultraviolet lamp 4 achieves good results. By engaging the locking groove 24 with the locking block 23, the bottom of the cleaning plate 7 with the first sliding block 6 can be made more stable, preventing shaking caused by water flow. By setting the limiting plate 25, the movement position of the connecting block 21 can be restricted, preventing the connecting block 21 from coming out of the second circular groove 19 due to the elasticity of the third spring 20, thus ensuring the stability of the connection between the first sliding block 6 and the cleaning plate 7.
