Description

Technical Field

[0001] The utility model belongs to the technical field of water filtration, and specifically relates to a laboratory ultrapure water machine and an ultraviolet sterilizer thereof. Background Art

[0002] The use of ultraviolet sterilizers in laboratory ultrapure water is a common and effective water treatment method. Ultraviolet (UV) sterilizers kill or inactivate microorganisms in water, including bacteria, viruses, and algae, by emitting ultraviolet light of a specific wavelength, thereby ensuring the high cleanliness and biosafety of ultrapure water and meeting the requirements of laboratory water.

[0003] However, at present, ultraviolet lamps are directly installed inside ultraviolet sterilizers to disinfect and sterilize water. In addition to bacteria and microorganisms, the water also contains particulate matter, floating objects and lint impurities, which cannot be effectively cleaned by ultraviolet lamps. On the one hand, some impurities will adhere to the lamps during the flow process, affecting the sterilization effect of the lamps. On the other hand, it is not convenient to further filter and purify the water quality. After the water is discharged, it needs to be treated by other facilities. Utility Model Content

[0004] The purpose of this utility model is to provide a laboratory ultrapure water machine and its ultraviolet sterilizer, which can filter the water entering the ultraviolet sterilizer, increase the cleanliness of the water, and prolong the contact time between the water flow and the lamp tube.

[0021] In order to make the purpose and advantages of this utility more clear, the utility is described in detail below with reference to the embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of this utility and does not strictly limit the scope of protection specifically requested by this utility.

[0022] like Figure 1-Figure 4As shown, the laboratory ultrapure water machine includes a shell 1, two brackets are fixedly connected to the bottom of the shell 1, the right end face of the shell 1 is an opening, the right end face of the shell 1 is equipped with a guide shell 2, the inner wall of the shell 1 is fixedly connected with a partition 3, the upper and lower side walls of the partition 3 and the inner wall of the shell 1 are respectively fixedly connected with a guide plate 4, the right side wall of the partition 3 is flush with the right end face of the shell 1, the inner cavity of the guide shell 2 is provided with a filter assembly, two connecting pipes 5 are fixedly connected to the side wall of the shell 1 near the left side, and two disinfection lamp tubes 6 are installed on the side wall of the guide shell 2, and the disinfection lamp tube 6 extends into the shell 1.

[0023] like Figure 2 and Figure 3 As shown, the filter assembly includes an annular plate 8 fixedly connected to the inner wall of the guide shell 2, and a filter element 7 is provided on the left side of the annular plate 8. The filter element 7 is divided into coarse filtration and fine filtration from top to bottom. The coarse filtration and fine filtration are respectively located on the upper and lower sides of the partition 3. Several screws 9 are assembled between the annular plate 8 and the filter element 7. Two through holes 10 are provided on the filter element 7 to match the disinfection lamp tube 6.

[0024] Among them, the filter element 7 uses activated carbon, RO membrane, filter cotton and other filter materials. When the filter element 7 needs to be replaced, the disinfection lamp tube 6 and the diversion shell 2 need to be removed simultaneously. When replacing the filter element 7, the disinfection lamp tube 6 and the diversion shell 2 can also be cleaned and maintained at the same time to avoid scale and impurities adhering to their surfaces.

[0025] like Figure 3 As shown, the left side wall of the filter element 7 is provided with a limiting groove 11, and the partition 3 abuts against the side wall of the limiting groove 11. During use of the filter element 7, the limiting groove 11 and the partition 3 are in a tight fit, effectively preventing water from flowing directly from the upper layer of the partition 3 to the lower layer through the gap between the filter element 7 and the partition 3, thereby achieving a sealing effect.

[0026] like Figure 4 As shown, a sealing ring 12 is fixedly connected to the right end face of the shell 1, and a sealing groove 13 is formed on the left end face of the guide shell 2. The sealing ring 12 is adapted to the sealing groove 13. Flanges 14 are fixedly connected to the side walls of the shell 1 and the guide shell 2 near the end faces, and several bolts 15 are assembled between the two side flanges 14.

[0027] Among them, when the shell 1 and the guide shell 2 are locked by the bolts 15 on both sides, the sealing ring 12 is stuck in the sealing groove 13. Since the sealing ring 12 is made of flexible material, when the sealing ring 12 is squeezed and deformed, the sealing groove 13 can be filled to ensure that there will be no leakage during the water treatment process. Moreover, in actual application, a layer of rubber ring will also be filled between the flanges 14 to further ensure the sealing performance.

[0028] like Figure 2As shown, the guide plates 4 are all inclined. Two rows of guide plates 4 are set on the upper and lower sides of the partition 3, respectively. The upper guide plates 4 are all inclined towards the right, and the lower guide plates 4 are all inclined towards the left. The guide plates 4 on the same side are staggered. The water flow can be turned along the direction of the guide plates 4, increasing the contact surface between the water flow and the disinfection lamp 6.

[0029] An ultraviolet sterilizer is used for the above-mentioned laboratory ultrapure water machine.

[0030] The working principle of this utility model is as follows: when water flows into the interior of the shell 1 through the upper connecting pipe 5, the water flows in contact with the disinfection lamp tube 6. At the same time, as the guide plate 4 is tilted, the water flows continuously in the shell 1, which is used to increase the contact surface with the disinfection lamp tube 6. The water flows through the upper filter element 7 through the internal pressure of the shell 1, and coarsely filters the impurities in the water flow. The water flows into the interior of the guide shell 2. When the pressure reaches a certain level, the water flows through the lower filter element 7 and enters the lower side of the partition 3, and finely filters the water flow. After the water flows into the lower side of the partition 3, it is disinfected again, thereby effectively extending the contact time between the water flow and the disinfection lamp tube 6 and improving the disinfection effect.

[0031] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
