Description

Technical Field

[0001] The utility model relates to the technical field of ultrapure water machines, and more specifically to an ultrapure water column for a laboratory ultrapure water machine. Background Art

[0002] Ultrapure water machines use pretreatment, reverse osmosis technology, ultrapurification, and post-treatment to nearly completely remove conductive media from water and reduce undissociated colloids, gases, and organic matter to very low levels. Ultrapure water machines are also known as ultrapure water devices, ultrapure water equipment, ultrapure water meters, ultrapure water systems, and laboratory ultrapure water devices. Laboratory ultrapure water machines primarily consist of purification columns, activated carbon filters, reverse osmosis membranes, and precision filter cartridges. The purification column, sometimes also called an ultrapurification column, deeply desalinates reverse osmosis pure water, ultimately achieving Grade 1 or ultrapure water quality. Its principle is ion exchange.

[0003] After searching, the utility model patent with announcement number CN221191927U discloses an ultrapure water column for a laboratory ultrapure water machine, including a top cover and a base, wherein both sides of the lower surface of the top cover are provided with mounting grooves, and the two mounting grooves are symmetrically distributed with the top cover, and the upper surface of the base is provided with placement grooves corresponding to the mounting grooves, and an annular groove is provided on one side of the inner side of the placement grooves, and two purification column bodies are installed between the top cover and the base through the two mounting grooves and the two placement grooves; the present application adapts the limit block to the size of the opening so that the limit block is aligned with the opening, and then it is convenient to install the filter element into the interior of the connector along the position of the opening, and then the pull ring is turned to rotate the two limit blocks on the outer wall of the filter element into the inner side of the cavity, so as to facilitate the installation of the filter element into the interior of the purification column body and the removal of the filter element from it, thereby achieving the purpose of facilitating the installation and disassembly of the filter element. However, the above patent still has the following shortcomings: the steps for replacing and disassembling the filter element are relatively cumbersome and inconvenient to operate. In addition, after the water is first filtered using the microporous filter, the top surface is easily accumulated with filtered matter, which affects the flow of water if it is not cleaned. Manual cleaning is often inconvenient. For this reason, we propose an ultrapure water column for a laboratory ultrapure water machine. Utility Model Content

The bottom of each water inlet pipe 5 is fixedly connected to the top of the two water inlet pipes 4. The bottom of each water inlet pipe 5 is fixedly connected to the bottom of the two water inlet pipes 4. The scraping mechanism 6 is provided at the bottom of each water inlet pipe 5. The inner cavity of each water inlet pipe 5 is sleeved with a purification cylinder 8. The bottom of the inner cavity of each water inlet pipe 5 is fixedly sleeved with a lower support net 9. The inner cavity of each water inlet pipe 5 is provided with an ion exchange resin 10. The top of each water inlet pipe 5 is fixedly connected to the top of the two water inlet pipes 4.

[0028] For details, please refer to Figure 2 and Figure 6 The scraping mechanism 6 includes a rotating base 14 fixedly connected to the bottom surface of the cylinder cover 3, and the middle part of the rotating base 14 is rotatably connected to a rotating rod 15. The bottom end of the rotating rod 15 is fixedly connected to a scraper 17. The bottom surface of the scraper 17 is in contact with the top surface of the upper filter 12. The top end of the rotating rod 15 extends to the inner cavity of the water inlet cylinder 4 and is fixedly connected to a water wheel 16.

[0029] In this embodiment, the water wheel 16 is located directly below the end of the water inlet pipe 5 so that water can drive the water wheel 16 to rotate.

[0030] For details, please refer to Figure 4 A drainage pipe 19 is fixedly sleeved at the bottom ends of the two purification column bodies 1 , and a fixed sleeve plate 18 is fixedly sleeved between the two purification column bodies 1 .

[0031] In this embodiment, the two purification column bodies 1 are connected by a fixed sleeve 18 , and the purified water is discharged through a drain pipe 19 .

[0032] For details, please refer to Figures 2 to 4 The inner wall of the purification column body 1 is in contact with the outer side of the purification cylinder 8 , and the inner wall of the square groove 13 is in contact with the side of the L-shaped card strip 7 .

[0033] In this embodiment, the stability and sealing of the purification cartridge 8 in the inner cavity of the purification column body 1 are ensured, and the stability of the L-shaped clip 7 in the square groove 13 is also ensured.

[0034] For details, please refer to Figure 5 , the top surface of the cylinder ring cover 11 is flush with the top surface of the upper filter plate 12.

[0035] In this embodiment, it is ensured that the scraper 17 can smoothly scrape the top surfaces of the cylinder ring cover 11 and the upper filter plate 12 to clean off the impurities.

[0036] For details, please refer to Figure 2 and Figure 3 The cylinder ring cover 11 and the upper filter disc 12 are located in the inner cavity of the storage cylinder 2.

[0037] In this embodiment, it is ensured that the impurities cleaned off the upper filter disc 12 are collected into the inner cavity of the impurity storage barrel 2 .

[0038] Working principle: When in use, the water to be purified is introduced into the inner cavity of the water inlet cylinder 4 through the water inlet pipe 5, and the water in the water inlet cylinder 4 is filtered by the upper filter disc 12. The filtered water enters the purification cylinder 8 for purification, and the positive ions in the water are exchanged with the H ions in the ion exchange resin 10, and the negative ions in the water are exchanged with the OH- ions on the ion exchange resin 10, thereby achieving the purpose of purifying water. The purified water re-enters the purification column body 1 from the lower support net 9 and is discharged from the drain pipe 19. In addition, when the water enters the water inlet cylinder 4, the water drives the water wheel 16 to rotate, and the rotation of the water wheel 16 drives the rotating rod 15 and the scraper 17 to rotate, and the scraper 17 is used to scrape the impurities filtered out of the top surface of the upper filter disc 12, and the scraper 17 pushes the impurities to be moved by centrifugal force to the storage cylinder 2 for temporary collection, to ensure that the upper filter disc 12 will not be blocked;

[0039] When the ion exchange resin 10 needs to be replaced, the water inlet pipe 5 is separated from the pipeline on the ultrapurifier, and the cylinder cover 3 is rotated to remove it from the storage cylinder 2, so that the cylinder cover 3 and the water inlet cylinder 4 are taken off from the storage cylinder 2. At this time, the impurities in the inner cavity of the storage cylinder 2 can be cleaned. In addition, the cylinder ring cover 11 and the purification cylinder 8 are directly removed from the purification column body 1. The cylinder ring cover 11 is rotated to remove it from the purification cylinder 8, so as to replace the ion exchange resin 10. After the ion exchange resin 10 is replaced, the purification cylinder 8 is placed back into the purification column body 1 for use.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and improved ideas of the present invention, which should be covered by the protection scope of the present invention.
