Technical Field

[0001] This invention belongs to the field of sterilization technology, and specifically relates to a photoelectric Ag sterilization system. Background Technology

[0002] Organic waste comes in many forms, and the methods for treating it also vary. Generally speaking, it can be divided into three main categories: physical methods, chemical methods, and biochemical methods.

An electromagnet is fixedly connected to the inner wall of the groove near the outer cover. When the electromagnet is energized, the direction of the magnetic poles generated is the same as the direction of the magnetic poles of the slider.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0017] This invention provides a photoelectric Ag sterilization system, such as Figures 1 to 9 As shown, the system includes a main pipe 1, with an injection pipe 2 and an outlet pipe 3 connected to it on both sides. Valves are provided on the outside of the injection pipe 2 and the outlet pipe 3. An electrochemical element 4 is provided on the outside of the outlet pipe 3. A lamp tube 5 is fixedly installed inside the main pipe 1. An outer cover 6 is fitted around the lamp tube 5. The outer cover 6 is a quartz tube. One end of the outer cover 6 is rotatably connected to the inner wall of the main pipe 1. A cylinder 7 is fixedly installed on the inner wall of the main pipe 1. Horizontal openings are equidistantly arranged around the inner wall of the cylinder 7. A horizontal plate 8 is provided inside the horizontal openings. A reaction layer is coated on both the horizontal plate 8 and the inner wall of the cylinder 7. The reaction layer cooperates with the electrochemical element 4. A cavity is symmetrically opened on the side of the horizontal plate 8 away from the outer cover 6. A pressure rod 9 is slidably installed in the cavity. A first spring is provided on the side of the pressure rod 9 near the outer cover 6. A scraper 10 is fixedly installed on the side of each pair of opposing pressure rods 9 away from the outer cover 6. A drive assembly for driving the horizontal plate 8 to descend and flip is provided on the outside of the horizontal plate 8. A rotating assembly for driving the outer cover 6 to rotate is provided on the outside of the outer cover 6.

[0018] The cylinder 7, the horizontal plate 8, and the reaction layer form a whole, called the catalyst plate. The light source required for the catalyst plate can be either a mercury lamp or a visible light source. In use, an external pump injects an organic-containing liquid or gas into the main pipe 1 through the injection pipe 2, allowing the organic substance to enter the main pipe 1. The lamp 5 is then turned on, and the catalyst plate inside the main pipe 1 is irradiated by the lamp 5, generating an electric hole. ), hydroxyl radicals (·OH), superoxide ions ( The positive electrode (+) of electrochemical element 4 is connected to the catalyst plate, providing positive charge to the catalyst plate. When organic matter in the liquid or gas comes into contact with the catalyst plate, the following reaction mechanism occurs: ;

[0019] Organic matter is degraded into carbon dioxide and water, which are then discharged from the discharge pipe 3, thereby achieving sterilization of liquids or gases containing organic matter.

[0020] When the outer cover 6 needs to be cleaned, water can be continuously supplied to the main pipe 1 through the injection pipe 2. The supplied water flows out through the discharge pipe 3. As the water flows, it will cooperate with the rotating component to drive the outer cover 6 to rotate. At the same time, the drive component will drive the horizontal plate 8 to descend. The release force of the first spring will cause the pressure rod 9 and the scraper 10 to pop out away from the horizontal plate 8. When the horizontal plate 8 leaves the horizontal opening, the horizontal plate 8 rotates so that the scraper 10 faces downward. Finally, the scraper 10 comes into contact with the surface of the outer cover 6. As the outer cover 6 rotates, the scraper 10 removes the impurities on the surface of the outer cover 6. The flowing water carries away the impurities, thus cleaning the outer cover 6. After cleaning, the drive component reverses its operation to reset the horizontal plate 8 and the scraper 10. This ensures that the outer cover 6 remains clean during subsequent sterilization treatment, and no scale will appear on its surface. This will prevent scale from blocking the light from the lamp tube 5, thus avoiding affecting the sterilization effect.

[0021] like Figures 2 to 3 As shown, the drive assembly includes a rotating shaft 11 fixedly connected to both ends of the horizontal plate 8. A gear 12 is fixedly sleeved on the outside of the rotating shaft 11 near the injection pipe 2. A rack 13 corresponding to the position of the gear 12 is fixedly installed on the inner wall of the main pipe 1. The rack 13 has a missing tooth section on the side near the gear 12. A vertical plate 15 corresponding to the rotating shaft 11 is fixedly installed on the inner wall of the main pipe 1. A groove is opened on the side of the vertical plate 15 near the rotating shaft 11. A slider 16 is slidably installed in the groove. The side of the slider 16 away from the outer cover 6 is fixedly connected to the inner wall of the groove through a second spring. One end of the rotating shaft 11 is rotatably connected to the slider 16. A torsion spring 14 is sleeved on the outside of the rotating shaft 11. The two ends of the torsion spring 14 are fixedly connected to the slider 16 and the rotating shaft 11 respectively. The slider 16 is a magnet. An electromagnet 18 is fixedly connected to the inner wall of the groove on the side near the outer cover 6. When the electromagnet 18 is energized, the direction of the magnetic poles generated is the same as the direction of the magnetic poles of the slider 16.

[0022] In use, the electromagnet 18 is de-energized to demagnetize it, thus removing its repulsion on the slider 16. The second spring, in its compressed state, releases its force, causing the slider 16, rotating shaft 11, gear 12, and horizontal plate 8 to move closer to the outer cover 6, making the horizontal plate 8 leave the horizontal opening. At the same time, the first spring releases its force, causing the pressure rod 9 and scraper 10 to pop out away from the horizontal plate 8. After the horizontal plate 8 and scraper 10 leave the horizontal opening, the torque of the torsion spring 14 can keep the horizontal plate 8 and rotating shaft 11 in their current state. As the horizontal plate 8 continues to descend, the gear 12 moves along the missing tooth section to mesh with the teeth on the rack 13. Then, the gear 12 rolls along the teeth, causing the rotating shaft 11 and horizontal plate 8 to rotate, causing the pressure rod 9 and scraper 10 to rotate as well. Finally, after the slider 16 contacts the electromagnet 18, the scraper 10 rotates to face the outer cover 6 and contact its surface, which can activate the electromagnet 18 to make it magnetic, thus repelling the slider 16 and resetting it. Conversely, the horizontal plate 8 and scraper 10 can be reset.

[0023] likeFigure 2 As shown, the rotating assembly includes a rotating rod 19 fixedly connected to the middle of the end of the outer cover 6 away from the injection pipe 2, and an impeller 20 is provided at the end of the rotating rod 19 away from the outer cover 6.

[0024] The water flow impacts the impeller 20, causing it to rotate along the rotating rod 19 and the outer cover 6, thus driving the outer cover 6.

[0025] like Figure 2 , Figure 3 , Figure 8 and Figure 9 As shown, a piston body 17 is provided at the rotatable connection between the outer cover 6 and the inner wall of the main pipe 1. An annular opening is provided on the side of the outer cover 6 near the injection pipe 2. A telescopic pipe 21 is fixedly connected inside the annular opening. A mounting cavity is symmetrically provided inside the side of the outer cover 6 near the injection pipe 2. A connecting rod 22 is slidably installed in the mounting cavity. A push plate 23 is fixedly connected to one end of the connecting rod 22 located in the mounting cavity. A third spring is sleeved on the outside of the connecting rod 22. The third spring is located in the mounting cavity. The end of the connecting rod 22 away from the push plate 23 extends to the outside of the mounting cavity and is fixedly connected to the inner wall of the annular opening. A pulling assembly is provided on the outside of the outer cover 6 to drive it to move away from the injection pipe 2.

[0026] Water flow impacts the impeller 20, causing it to rotate along the rotating rod 19 and the outer cover 6. The outer cover 6 rotates along the other end via the connecting rod 22. Simultaneously, the pulling assembly drives the outer cover 6, along with the connecting rod 22 and the push plate 23, to move away from the injection pipe 2. At the same time, the push plate 23 compresses the third spring, causing it to deform and generate force. Subsequently, the driving assembly releases the pulling force on the outer cover 6, and the deformed third spring quickly releases its force, causing the push plate 23 and the connecting rod 22 to return to their original positions. This causes the push plate 23 to collide with the inner wall of the mounting cavity, generating vibration, which is then transmitted to the outer cover 6, causing it to vibrate. By continuously driving the outer cover 6 with the pulling assembly and then releasing the drive, the outer cover 6 can be continuously vibrated in conjunction with the third spring, the push plate 23, and the connecting rod 22. This vibration can then dislodge and remove the clumps attached to the outer cover 6, making it easier for the scraper 10 to clean them.

[0027] like Figure 9 As shown, the pulling assembly includes a drive block 24 fixedly connected to a vertical plate 15 near the impeller 20, and a drive rod 25 that cooperates with the drive block 24 is fixedly installed equidistantly around the outside of the rotating rod 19.

[0028] When the impeller 20 rotates with the rotating rod 19, the drive rod 25 rotates accordingly. After the drive rod 25 rotates to contact the drive block 24, it moves along the surface of the drive block 24 away from the injection pipe 2, thereby moving the rotating rod 19 and the outer cover 6. The outer cover 6 moves the connecting rod 22 and the push plate 23 away from the injection pipe 2. At the same time, the push plate 23 compresses the third spring to deform and generate force. When the drive rod 25 leaves the drive block 24, the deformed third spring quickly releases its force and resets the push plate 23 and the connecting rod 22, causing the push plate 23 to collide with the inner wall of the mounting cavity and generate vibration.

[0029] like Figure 9 As shown, the drive block 24 is specifically configured as a block-shaped component with an arc surface on one side, and the arc surface can contact the drive rod 25.

[0030] This causes the drive rod 25 to move along the arc surface after it comes into contact with the arc surface, causing the drive rod 25 to move away from the injection pipe 2.

[0031] like Figure 2 As shown, the cylinder 7 and the horizontal plate 8 are made of opaque material, which is 304 stainless steel or 316 stainless steel.

[0032] like Figure 2 As shown, the reaction layer is composed of titanium, titanium dioxide, and silver. Titanium is plated on the inner wall of the cylinder 7 and the horizontal plate 8, titanium dioxide is plated on the surface of titanium, and silver is plated on the surface of titanium dioxide. The ratio of silver covering titanium dioxide is 1%-99%.

[0033] When the reaction layer is irradiated by lamp tube 5, the above-mentioned chemical reaction can occur.

[0034] Working principle: The cylinder 7, the horizontal plate 8, and the reaction layer form a whole, called the catalyst plate. The light source required for the catalyst plate can be either a mercury lamp or a visible light source. In use, an external pump injects an organic-containing liquid or gas into the main pipe 1 through the injection pipe 2, allowing the organic substance to enter the main pipe 1. The lamp 5 is then turned on, and the catalyst plate inside the main pipe 1 is irradiated by the lamp 5, generating an electric hole. ), hydroxyl radicals (·OH), superoxide ions ( The positive electrode (+) of electrochemical element 4 is connected to the catalyst plate, providing positive charge to the catalyst plate. When organic matter in the liquid or gas comes into contact with the catalyst plate, the following reaction mechanism occurs: ;

[0035] Organic matter is degraded into carbon dioxide and water, which are then discharged from the discharge pipe 3, thus sterilizing liquids or gases containing organic matter. During the entire reaction, the catalyst plate is not damaged, and only consumables such as lighting components need to be replaced, which greatly reduces the generation of waste such as consumables and improves the degradation efficiency of organic matter.

[0036] When the outer cover 6 needs cleaning, water can be continuously supplied to the main pipe 1 through the injection pipe 2. The water flows out through the discharge pipe 3. The water flow impacts the impeller 20, causing it to rotate the rotating rod 19 and the outer cover 6, thus driving the outer cover 6. The electromagnet 18 is de-energized, causing it to lose its magnetism and canceling its repulsion on the slider 16. The release force of the compressed second spring causes the slider 16, rotating shaft 11, gear 12, and cross plate 8 to move closer to the outer cover 6, causing the cross plate 8 to leave the horizontal opening. At the same time, the release force of the first spring causes the pressure rod 9 and scraper 10 to pop out away from the cross plate 8. After the cross plate 8 and scraper 10 leave the horizontal opening, the torque of the torsion spring 14 can hold the cross plate 8. The rotating shaft 11 remains in its current state. As the horizontal plate 8 continues to descend, the gear 12 moves along the toothed section until it meshes with the teeth on the rack 13. The gear 12 then rolls along the teeth, causing the rotating shaft 11 and the horizontal plate 8 to rotate, which in turn causes the pressure rod 9 and the scraper 10 to rotate. Finally, after the slider 16 contacts the electromagnet 18, the scraper 10 rotates to face the outer cover 6 and contact its surface. As the outer cover 6 rotates, the scraper 10 removes impurities from its surface. Combined with the flowing water, this cleans the outer cover 6. After cleaning, the electromagnet 18 can be activated to make it magnetic, causing it to repel the slider 16 and reset. Conversely, this allows the horizontal plate 8 to rotate. The repositioning of plate 8 and scraper 10 ensures that scraper 10 will not block the light from lamp 5, thus preventing interference with the reaction. Cleaning the outer cover 6 keeps it clean, preventing scale buildup and ensuring it doesn't block the light from lamp 5, thereby maintaining sterilization efficiency. Water flow impacts impeller 20, causing it to rotate rod 19 and outer cover 6. The outer cover 6 rotates via connecting rod 22. As impeller 20 rotates with rod 19, drive rod 25 rotates accordingly. When drive rod 25 contacts drive block 24, it moves away from injection pipe 2 along the surface of drive block 24. As the rotating rod 19 moves, the outer cover 6 moves away from the injection pipe 2, along with the connecting rod 22 and the push plate 23. At the same time, the push plate 23 compresses the third spring, causing it to deform and generate force. When the driving rod 25 leaves the driving block 24, the deformed third spring quickly releases its force, causing the push plate 23 and the connecting rod 22 to return to their original positions. This causes the push plate 23 to collide with the inner wall of the mounting cavity and generate vibration. As the driving rod 25 continuously contacts and separates from the driving block 24, the outer cover 6 can be continuously vibrated in conjunction with the third spring, the push plate 23, and the connecting rod 22. This vibration can then be used to shake off the clumps attached to the outer cover 6, making it easier for the scraper 10 to clean the clumps.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
