Description

Technical Field

[0001] The utility model relates to the technical field of direct drinking water disinfection, and more specifically, to a disinfection device for direct drinking water processing. Background Art

[0002] Direct drinking water is municipal tap water that has been deeply treated and purified through a special process. It is then transported through pipes to a central drinking point near a drinking point, where it is sterilized by ultraviolet radiation. After sterilization, it is transported to a nearby drinking point for storage, making it convenient for people to drink. Currently, when direct drinking water is disinfected, drinking water is transported through pipes to a disinfection device. During the transportation process, drinking water may carry impurities from the inside of the pipes. When it is directly passed into a sterilization tank for sterilization by ultraviolet light, impurities in the pipes are easily attached to the outside of the ultraviolet lamp, affecting the transmittance of the ultraviolet lamp and, in turn, the sterilization and disinfection effect. In addition, some disinfection devices are equipped with filter materials to filter impurities carried in drinking water. During the filtration process, the filter materials block and filter impurities in drinking water through the pores between the materials. However, the filtered impurities will remain on the filter materials, resulting in the pores between the materials being blocked, affecting the subsequent passage of drinking water.

A second water inlet pipe 19 is disposed at the top of the transparent tank 18, and a second water outlet pipe 20 is disposed at the bottom of the transparent tank 18. A first cover 21 is disposed at the top of the outer shell 16, and a second cover 22 is disposed at the bottom of the outer shell 16. The first cover 21 and the second cover 22 are both detachably connected to the outer shell 16 via bolts. The first cover 21 is provided with a first through hole 23 that mates with the second water inlet pipe 19, and the second cover 22 is provided with a second through hole 24 that mates with the second water outlet pipe 20. A third solenoid valve 25 is disposed on the second water inlet pipe 19, and a fourth solenoid valve 26 is disposed on the second water outlet pipe 20. A second U-shaped tube 27 is disposed between the first outlet pipe 15 and the second water inlet pipe 19. A support plate 30 is provided near the bottom of the support frame 1. The support frame 1 is provided with a first mounting hole 31 that cooperates with the water pipe 3, the filter tank 2 and the outer shell 16. The support plate 30 is provided with a second mounting hole 32 that cooperates with the slag storage tank 11 and the second water outlet pipe 20.

[0030] In this embodiment, the water supply pipe 3 is connected to a water pump and a municipal water treatment center to receive municipal water. The second water outlet pipe 20 is connected to a nearby drinking point, allowing the entire device to provide sterilized drinking water to nearby drinking points. After being fully treated at the municipal water treatment center, the drinking water is piped into the water supply pipe 3 and then flows along the first U-shaped pipe 4 into the filter tank 2. Filter cotton 7 intercepts and filters impurities carried along the pipe during the drinking water delivery process. The filtered drinking water then flows through the first outlet pipe 15, the second U-shaped pipe 27, and the second inlet pipe 19 into the transparent tank 18. When the transparent tank 18 is full, the water delivery is stopped, the third solenoid valve 25 is closed, and the drinking water in the transparent tank 18 is sterilized and disinfected by irradiation with ultraviolet light 17. After a period of sufficient sterilization and disinfection, the fourth solenoid valve 26 is opened to discharge the drinking water in the transparent tank 18 and deliver it to an external drinking point. After the water is fully discharged, the fourth solenoid valve 26 is closed and the third solenoid valve 25 is opened to resume water intake for a new round of sterilization and disinfection.

[0031] See also Figure 1-6 As an implementation of the slag storage tank 11 , a through slot 28 is provided on one side of the slag storage tank 11 , and an observation window 29 is fixedly provided at the through slot 28 .

[0032] More specifically, when the water pipe 3 stops delivering water, the first solenoid valve 12 is opened. At this time, the impurities intercepted on the filter cotton 7 will slowly settle into the slag discharge bucket 9 and pass through the connecting pipe 10 into the slag storage tank 11. When the water pipe 3 needs to deliver water, the first solenoid valve 12 is closed first to prevent the impurities in the slag storage tank 11 from floating up again under the action of the water flow. When there are more impurities in the slag storage tank 11, the first solenoid valve 12 is closed and the second solenoid valve 14 is opened to discharge the impurities in the slag storage tank 11.

[0033] In summary, when the overall equipment is in use or running: the water supply pipe 3 is connected to the water pump and the municipal water treatment center to receive municipal water, and the second water outlet pipe 20 is connected to the nearby drinking point. The entire device can provide sterilized drinking water to the nearby drinking points. After being fully treated by the municipal water treatment center, the drinking water is transported to the water pipe 3 through a pipeline and enters the filter tank 2 along the first U-shaped tube 4. The impurities carried in the pipeline during the drinking water transportation process are blocked and filtered by the filter cotton 7. The filtered drinking water enters the transparent tank 18 through the first outlet pipe 15, the second U-shaped tube 27 and the second water inlet pipe 19. When the transparent tank 18 is full of drinking water, the water supply is stopped, and the third solenoid valve 25 is closed. The drinking water in the transparent tank 18 is irradiated and sterilized by the ultraviolet lamp 17. After a period of sufficient sterilization and disinfection, the fourth solenoid valve 26 is opened to discharge the drinking water in the transparent tank 18 and transport it to an external drinking point. After the discharge is completed, the fourth solenoid valve 26 is closed, and the third solenoid valve 25 is opened to continue water intake for a new round of sterilization and disinfection.

[0034] When the water pipe 3 stops delivering water, the first solenoid valve 12 is opened. At this time, the impurities intercepted on the filter cotton 7 will slowly settle into the slag discharge bucket 9 and pass through the connecting pipe 10 into the slag storage tank 11. When the water pipe 3 needs to deliver water, the first solenoid valve 12 is closed first to prevent the impurities in the slag storage tank 11 from floating up again under the action of water flow. When there are more impurities in the slag storage tank 11, the first solenoid valve 12 is closed and the second solenoid valve 14 is opened to discharge the impurities in the slag storage tank 11.

[0035] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
