Description

Technical Field

[0001] This utility model relates to the field of ultraviolet disinfection technology, specifically to an ultraviolet disinfection device for direct drinking water. Background Technology

[0002] Ultraviolet (UV) disinfection is a physical disinfection method that mainly uses ultraviolet light with a wavelength of 240-280nm (the optimal sterilization wavelength is 254nm) to destroy the DNA / RNA structure of microorganisms, causing them to lose their ability to replicate, thereby achieving the purpose of disinfection.

[0003] The ultraviolet disinfection device for direct drinking water disclosed in authorization announcement number CN203440123U includes a round tank with a flat bottom at the top and bottom. An inlet is located on one side of the round tank, and an outlet is located on the other side. An ultraviolet lamp is installed inside the round tank. The beneficial effects of this utility model, achieved by adopting the above technical solution, are: sterilization and algae removal of tap water, ensuring drinking water safety.

[0004] Although the aforementioned patent can sterilize and kill algae in tap water, the dirt remaining on the surface of the quartz sand glass tube is difficult to clean effectively. Over time, a dirt layer will form, which will block the transmission of UV-C bands, thus reducing the sterilization efficiency. Utility Model Content

[0023] 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.

[0024] like Figure 1-4 As shown, this utility model provides a technical solution:

[0025] A direct drinking water ultraviolet sterilizer includes a sterilization chamber 1, with a cover 2 detachably mounted on its top via bolts. Several quartz sleeves 3 are fixedly mounted on the lower end of the cover 2. A sterilization mechanism is housed inside the quartz sleeves 3. The sterilization mechanism includes several threaded grooves 4 formed on the upper end of the cover 2, and ultraviolet lamps 5 movably fitted inside the quartz sleeves 3. The top of the ultraviolet lamps 5 extends to the outside of the sterilization chamber 1 and is fixedly connected to a lamp holder 6. Baffles 14 are fixedly mounted on both sides of the bottom center of the cover 2 and the bottom center of the sterilization chamber 1. A threaded head 7 is fixedly connected to the bottom of the lamp holder 6, outside the ultraviolet lamp 5. The threaded head 7 connects to the threaded grooves 4. A threaded connection is provided. A horizontal water inlet pipe 11 is fixedly installed on the upper left side of the disinfection box 1, and a horizontal water outlet pipe 12 is fixedly installed on the lower right side of the disinfection box 1. A self-cleaning mechanism is provided on the outside of the quartz sleeve 3. The self-cleaning mechanism includes a float assembly 8 that is movably sleeved on the outside of the quartz sleeve 3, and a cleaning ring 15 that is fixedly connected to the middle of the top of the float assembly 8. The inner wall of the cleaning ring 15 is connected to the outer wall of the quartz sleeve 3. The self-cleaning mechanism also includes a retaining ring 9 that is fixedly connected to the outer periphery of the bottom end of the quartz sleeve 3, and a counterweight ring 10 that is fixedly connected to the outer periphery of the cleaning ring 15. A vertical drain pipe 13 is fixedly installed on the right side of the bottom end of the disinfection box 1.

[0026] In this embodiment, by using the float assembly 8 in conjunction with the counterweight ring 10, the water level rises and falls to drive the cleaning ring 15 to perform bidirectional scraping and cleaning of the outer wall of the quartz sleeve 3, which effectively solves the problem of decreased UV-C band transmittance caused by dirt deposition on the surface of the quartz sleeve 3 in the prior art, and keeps the sterilization efficiency stable for a long time.

[0027] Furthermore, the meandering water flow path guided by the baffle 14, combined with the continuous irradiation of the ultraviolet lamp 5, extends the effective disinfection time of the water in the disinfection box 1.

[0028] Working principle: The water to be treated is continuously fed into the disinfection tank 1 through the inlet pipe 11. During the water circulation process, the float assembly 8 remains suspended, and the cleaning ring 15 remains in contact with the outer wall of the quartz sleeve 3 without causing a scraping effect. When cleaning of the quartz sleeve 3 is required, water is poured into the disinfection tank 1 through the inlet pipe 11 to raise the water level, pushing the float assembly 8 to the surface. The cleaning ring 15 then performs the first scraping and cleaning of the outer wall of the quartz sleeve 3. Subsequently, the water in the tank is discharged through the drain pipe 13. During the water level drop, the counterweight... Ring 10 drives float assembly 8 to move downward, and cleaning ring 15 performs a second reverse scraping and cleaning of the outer wall of quartz sleeve 3; ultraviolet lamp 5 continuously emits ultraviolet light under normal working conditions, which disinfects the circulating water through quartz sleeve 3; baffle 14 guides the water flow to form a meandering path to extend the disinfection time, and baffle ring 9 limits the movement range of float assembly 8; during maintenance, the disinfection mechanism can be removed as a whole by disassembling the box cover 2, and the mating structure of threaded head 7 and threaded groove 4 facilitates the individual disassembly and replacement of ultraviolet lamp 5.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
