Abstract
Description
Technical Field
[0001] This utility model relates to the field of circulating water disinfection technology, and in particular to a circulating water disinfection device. Background Technology
[0002] A circulating water disinfection device is a device used to continuously or periodically disinfect water in circulating water systems (such as cooling towers, industrial circulating water, swimming pools, central air conditioning, etc.). It aims to control the growth of microorganisms, prevent biological fouling, corrosion and the spread of diseases, and ensure water quality safety and efficient system operation.
[0003] Existing circulating water disinfection devices have a significant drawback: they lack an automatic cleaning function for the outer wall of the ultraviolet lamps. When wastewater flows through the disinfection pipes, suspended particles, algae residues, and other impurities carried in the water easily adhere to the outer surface of the ultraviolet lamps. Over time, these contaminants gradually accumulate to form a layer of dirt, severely hindering the transmission efficiency of ultraviolet rays. Because the ultraviolet rays are blocked by dirt, their sterilization effect is significantly reduced, resulting in incomplete disinfection. In addition, the accumulation of dirt may also cause poor heat dissipation of the lamps, shortening their service life.
[0004] Therefore, to address the problem that the existing circulating water disinfection devices lack a cleaning structure for ultraviolet lamps, which affects the disinfection effect, a new circulating water disinfection device can be designed. Utility Model Content
[0005] To overcome the problem that existing circulating water disinfection devices lack a cleaning structure for ultraviolet lamps, which affects the disinfection effect.
[0006] The technical solution of this utility model is as follows: a circulating water disinfection device, including a circulating pipe; and a rubber scraper ring. Two inlet and outlet ports are provided at the top of the circulating pipe. Fixed plates are provided at both ends of the circulating pipe, and multiple lamp holders are installed on each of the two fixed plates. Ultraviolet lamps are installed between corresponding pairs of lamp holders. A waterproof motor is installed on the left side of the right fixed plate. A lead screw is connected to the output end of the waterproof motor, which drives the lead screw to rotate. The left end of the lead screw is rotatably connected to the left fixed plate. A movable seat is threaded through the outer side of the lead screw. Four support rods are installed on the outer side of the movable seat. A sleeve is provided at the end of each support rod away from the movable seat, and the sleeve is slidably connected to the corresponding ultraviolet lamp. A rubber scraper ring is provided on the right side of the sleeve, and the rubber scraper ring is in contact with the outer wall of the ultraviolet lamp. Fixed components are provided on the left and right sides of the movable seat, and cleaning components are installed on the fixed components. Limiting components are provided on the front and rear sides of the movable seat. A sludge removal mechanism is provided on the bottom right side of the circulating pipe.
[0007] Preferably, by setting a waterproof motor, its output end can drive the lead screw to rotate during operation. When the lead screw rotates, it drives the moving seat that is threaded to it to move left and right, thereby causing the support rod to move the sleeve along the outer wall of the ultraviolet lamp tube. The rubber scraper ring can then scrape off the impurities adhering to the outer wall of the ultraviolet lamp tube, ensuring the transmittance of ultraviolet light and guaranteeing the disinfection quality. This solves the problem that existing circulating water disinfection devices do not have a cleaning structure for the outer wall of the ultraviolet lamp tube during use. During the disinfection process of sewage inside the pipe, particulate residues carried by the sewage will adhere to the inner wall of the ultraviolet lamp tube, affecting the normal transmission of ultraviolet light and thus affecting the disinfection effect.
[0008] Preferably, the fixing component includes fixing rings and fixing screws. Fixing rings are provided on both the left and right sides of the movable base, and multiple fixing screws are connected to the fixing rings. The fixing rings are fixed to the movable base by the fixing screws.
[0009] Preferably, the cleaning component includes retaining rings and bristles, with retaining rings provided on the side of the two retaining rings away from the moving base, and bristles provided on the inner wall of the retaining rings.
[0010] Preferably, the limiting assembly includes a limiting rod and a positioning rod. The limiting rod is installed on both the front and rear sides of the movable seat, and the positioning rod is installed between the two fixed plates. The limiting rod and the positioning rod are slidably connected.
[0011] Preferably, the slag removal mechanism includes a slag discharge component and a connecting component. The slag discharge component is used to discharge the impurities scraped off by the rubber scraper ring, and the connecting component is used to position the slag discharge component.
[0012] Preferably, the slag discharge assembly includes a slag discharge pipe, a sealing groove, and a sealing cover. The slag discharge pipe is located on the bottom right side of the circulation pipe, and a sealing groove is provided at the bottom of the slag discharge pipe. The bottom of the slag discharge pipe is connected to the sealing cover through the sealing groove.
[0013] Preferably, the connecting assembly includes connecting plates and positioning screws. Four connecting plates are provided on the outer side of the slag discharge pipe and the sealing cover. Positioning screws are connected to the connecting plates. The slag discharge pipe and the sealing cover are fixed by the connecting plates and positioning screws.
[0014] The beneficial effects of this utility model are:
[0015] By installing a movable rubber scraper ring on the outside of the ultraviolet lamp tube, dust, scale, and other impurities adhering to the outer wall of the lamp tube can be effectively removed. With the reciprocating movement of the rubber scraper ring, the surface of the ultraviolet lamp tube remains clean, avoiding the obstruction of ultraviolet rays by contaminants and significantly improving the transmission efficiency of ultraviolet rays. This active cleaning method overcomes the defect of traditional fixed lamp tubes that are prone to scale buildup, ensuring the stability of ultraviolet radiation intensity during the disinfection process, thereby greatly improving the overall disinfection effect. At the same time, the automatic scraping design reduces the frequency of manual maintenance, ensuring continuous disinfection quality and reducing operating costs, making it particularly suitable for high-standard disinfection sites that require long-term stable operation.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figures 1-5This utility model provides an embodiment of a circulating water disinfection device, including a circulating pipe 1 and a rubber scraper ring 11. The top of the circulating pipe 1 has two inlet and outlet ports 2. Fixed plates 3 are located at both ends of the circulating pipe 1. Multiple lamp holders 4 are installed on each of the two fixed plates 3, and ultraviolet lamps 5 are installed between corresponding lamp holders 4. A waterproof motor 6 is installed on the left side of the right fixed plate 3. The output end of the waterproof motor 6 is connected to a lead screw 7, which drives the lead screw 7 to rotate. The left end of the lead screw 7 is rotatably connected to the left fixed plate 3. A movable seat 8 is threaded through the outer side of the lead screw 7. Four support rods 9 are installed on the outer side of the movable seat 8. A sleeve 10 is provided at the end of the support rod 9 away from the movable seat 8. The sleeve 10 is slidably connected to the corresponding ultraviolet lamp 5. A rubber scraper ring 11 is located on the right side of the sleeve 10. The rubber scraper ring 11 is connected to the ultraviolet lamp 5. The outer wall of the ultraviolet lamp tube 5 is fitted with a fixed component on the left and right sides of the movable seat 8. A cleaning component is installed on the fixed component. Limit components are set on the front and rear sides of the movable seat 8. A sludge cleaning mechanism is set on the bottom right side of the circulation pipe 1. A waterproof motor 6 is set. During operation, the output shaft directly drives the lead screw 7 to rotate. The rotating lead screw 7 converts the rotational motion into linear motion through the threaded engagement with the movable seat 8, causing the movable seat 8 to move back and forth axially. During this process, the support rod 9, which is rigidly connected to the movable seat 8, drives the sleeve 10 to slide axially along the outer surface of the ultraviolet lamp tube 5, forcing the rubber scraper ring 11 on the sleeve 10 to mechanically scrape the outer wall of the lamp tube, effectively removing dirt and impurities attached to the surface of the lamp tube. This design can continuously maintain the cleanliness of the surface of the ultraviolet lamp tube 5, ensure the transmission efficiency of ultraviolet radiation, and thus ensure a stable disinfection and sterilization effect.
[0024] Please see Figures 2-4 In this embodiment, the fixing component includes a fixing ring 121 and fixing screws 122. Fixing rings 121 are provided on both the left and right sides of the movable base 8. Multiple fixing screws 122 are connected to the fixing rings 121, and the fixing rings 121 are fixed to the movable base 8 by the fixing screws 122. By setting the fixing screws 122, the fixing rings 121 and the movable base 8 can be fixedly installed. The cleaning component includes a fixing ring 131 and bristles 132. A fixing ring 131 is provided on the side of each fixing ring 121 away from the movable base 8. The inner wall of the fixing ring 131 is provided with… The brush 132 is used to clean the thread grooves on the surface of the lead screw 7 during the movement of the movable seat 8, preventing the accumulation of impurities inside the thread grooves from affecting normal transmission. The limiting component includes a limiting rod 141 and a positioning rod 142. The limiting rod 141 is installed on both the front and rear sides of the movable seat 8, and the positioning rod 142 is installed between the two fixed plates 3. The limiting rod 141 and the positioning rod 142 are slidably connected. By setting the limiting rod 141 and the positioning rod 142, the rotation of the movable seat 8 can be restricted, ensuring the transmission efficiency of the lead screw 7.
[0025] Please see Figures 1-5 In this embodiment, the slag removal mechanism includes a slag discharge component and a connecting component. The slag discharge component is used to discharge impurities scraped off by the rubber scraper ring 11, and the connecting component is used to position the slag discharge component. The slag discharge component includes a slag discharge pipe 151, a sealing groove 152, and a sealing cover 153. The slag discharge pipe 151 is provided on the bottom right side of the circulation pipe 1. The bottom of the slag discharge pipe 151 has a sealing groove 152. The bottom of the slag discharge pipe 151 is connected to the sealing cover 153 through the sealing groove 152. By setting the slag discharge pipe 151, the circulation pipe 1 is installed at an overall inclination. When the equipment is stopped, the ultraviolet lamp tube 5 is cleaned. When cleaning, the sealing cover 153 can be opened, and the scraped-off impurities will slide down into the slag discharge pipe 151 and be discharged under gravity. The connecting components include connecting pieces 154 and positioning screws 155. Four connecting pieces 154 are provided on the outside of the slag discharge pipe 151 and the sealing cover 153. Positioning screws 155 are connected to the connecting pieces 154. The slag discharge pipe 151 and the sealing cover 153 are fixed by the connecting pieces 154 and the positioning screws 155. By setting the connecting pieces 154 and the positioning screws 155, the sealing cover 153 and the slag discharge pipe 151 can be fixed to avoid water leakage during daily use.
[0026] During operation, circulating water enters the pipe through the inlet and outlet 2 of the circulating pipe 1 and flows inside. The ultraviolet lamp 5 emits ultraviolet light to disinfect the water. When cleaning is required, the water flow is stopped, the waterproof motor 6 starts and drives the lead screw 7 to rotate. The lead screw 7 drives the moving seat 8 to move left and right. The moving seat 8 drives the sleeve 10 to slide along the ultraviolet lamp 5 through the support rod 9. The rubber scraper ring 11 on the sleeve 10 scrapes away the impurities adhering to the outer wall of the ultraviolet lamp 5 to ensure the ultraviolet transmittance. When the moving seat 8 moves, the fixing ring 131 and the bristles 132 on the fixing ring 121 clean the thread groove of the lead screw 7 to prevent the accumulation of impurities from affecting the transmission. At the same time, the limit rod 141 and the positioning rod 142 restrict the rotation of the moving seat 8. The sealing cover 153 of the slag discharge pipe 151 is opened, and the scraped impurities are discharged from the slag discharge pipe 151 under the action of gravity, thereby ensuring the disinfection quality.
[0027] Through the above steps, when the waterproof motor 6 starts, the rotational motion of the lead screw 7 interacts with the internal thread of the moving seat 8, transforming it into a precise linear displacement of the moving seat 8. This mechanical transmission method allows the support rod 9, which is fixed to the moving seat 8, to precisely control the movement trajectory of the sleeve 10, enabling the sleeve 10 to slide smoothly along the axial direction of the ultraviolet lamp tube 5. During this process, the rubber scraper ring 11 at the front end of the sleeve 10 performs circumferential scraping on the outer surface of the lamp tube, effectively removing contaminants such as scale and biofilm adhering to the quartz glass tube wall. This dynamic cleaning mechanism can effectively maintain the light transmittance of the ultraviolet lamp tube 5, ensuring the stability of the ultraviolet radiation intensity during the disinfection process, thereby meeting the strict requirements of medical and health institutions for disinfection quality. This solves the problem that existing circulating water disinfection devices do not have a cleaning structure for the outer wall of the ultraviolet lamp tube 5 during use, and that during the disinfection process inside the pipe, particulate matter residues carried by sewage will adhere to the inner wall of the ultraviolet lamp tube 5, affecting the normal propagation of ultraviolet light and thus affecting the disinfection effect.
