[0002] An ultrapure water system, also known as an ultrapure water purifier, ultrapure water equipment, ultrapure water instrument, ultrapure water system, or laboratory ultrapure water purifier, is a water treatment device that uses pretreatment, reverse osmosis technology, ultrapure treatment, and post-treatment methods to almost completely remove conductive media from water, and also removes non-dissociated colloidal substances, gases, and organic matter to a very low level. It is mainly used to produce high-purity water to meet the high water quality requirements of scientific research, biology, medicine, electronics, chemical industry and other fields.

[0003] Traditional ultrapure water systems achieve single-pass filtration and purification of liquids through internal filter media. However, the filter media is a consumable and needs to be replaced periodically. After prolonged use, the filter media gradually accumulates impurities, organic matter, microorganisms, and other contaminants from the water, leading to clogging and reduced filtration efficiency. If the filter media is not replaced in time, these impurities and contaminants will remain in the equipment, requiring repeated single-pass filtration over a long period. This not only affects water quality but may also have adverse effects on human health or experimental results. Utility Model Content

[0004] To address the shortcomings of existing technologies, such as the problem that if filter media is not replaced in a timely manner, these impurities and contaminants will remain in the equipment and require repeated filtration over a long period of time, which not only affects water quality but also has adverse effects on human health or experimental results, this invention proposes a filtration and purification device for ultrapure water systems.

The surface of the connecting block is movably inserted into the inner wall of the connecting groove. An avoidance groove is opened on one side of the filter media. The inner wall of the avoidance groove is in contact with the surface of the connecting rod.

[0007] Preferably, a support ring is fixedly connected to the inner wall of the connecting cylinder, and one side of the support ring is in contact with one side of the water-passing plate.

[0008] Preferably, a limiting block is fixedly connected to the inner wall of the connecting cylinder, and limiting grooves are formed on the surface of the water-passing plate and the surface of the filter material. The inner wall of the limiting groove is slidably connected to the surface of the limiting block.

[0009] Preferably, the bottom of the connecting cylinder is fixedly connected to a liquid guide shell, one side of the liquid guide shell is fixedly connected to a first liquid outlet pipe, and the surface of the liquid guide shell is fixedly connected to a second liquid outlet pipe.

[0010] Preferably, a first control valve is fixedly installed on the surface of the first outlet pipe, and a second control valve is fixedly installed on the surface of the second outlet pipe.

[0012] Preferably, a protective cover is fixedly connected to one end of the first liquid outlet pipe, and a baffle plate is fixedly connected to the inner wall of the protective cover. The baffle plate is made of rubber.

[0013] The advantages of this utility model are:

[0014] This invention uses an external connecting pipe to fix the filtration and purification device to the required ultrapure water machine. The filter media can perform secondary filtration on the water filtered inside the ultrapure water machine. When replacing the filter media, the connecting cylinder is separated from the sealing cap, and the installation mechanism is fixedly connected to the sealing cap. All filter media are semi-circular, and the semi-circular filter media are spliced ​​into a whole circle by connecting blocks and connecting grooves. The clearance groove fits against the surface of the connecting rod. Pure water undergoes secondary filtration and purification through the filter media and is discharged from the water plate. This achieves the convenience of replacing the filter media in the filtration and purification device, and minimizes the need for secondary filtration of liquids when the consumables inside the ultrapure water machine are not replaced in time. It solves the problem that if the filter media is not replaced in time, these impurities and contaminants will continue to remain in the equipment, requiring repeated filtration over a long period of time, which not only affects water quality but also has adverse effects on human health or experimental results.

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 scope of protection of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a filtration and purification device for an ultrapure water system. (Refer to...) Figures 1 to 3 A filtration and purification device for an ultrapure water machine includes a connecting cylinder 1, a sealing cap 2 fixedly connected to the top of the connecting cylinder 1, an external pipe 3 fixedly connected to one side of the sealing cap 2, and an installation mechanism 4 provided on one side of the sealing cap 2.

[0024] The mounting mechanism 4 includes a connecting rod 401, the surface of which is fixedly connected to the inner cavity of the sealing cover 2. A water-passing plate 402 is fixedly connected to the surface of the connecting rod 401. Filter media 403 is provided on one side of the water-passing plate 402. There are several filter media 403. A connecting groove 404 is opened on one side of the filter media 403. A connecting block 405 is fixedly connected to one side of the filter media 403. The surface of the connecting block 405 is movably inserted into the inner wall of the connecting groove 404. An avoidance groove 406 is opened on one side of the filter media 403. The inner wall of the avoidance groove 406 is attached to the surface of the connecting rod 401. This is a filtration and purification device for an ultrapure water machine. The connecting cylinder 1 is fixedly connected to the sealing cover 2, and the water-passing plate 402 is connected to the outer pipe 3. The filtration and purification device is fixedly connected to the required ultrapure water machine. The filter media 403 can perform secondary filtration on the water filtered in the ultrapure water machine. When replacing the filter media 403, the connecting cylinder 1 is separated from the sealing cover 2, and the mounting mechanism 4 is fixedly connected to the sealing cover 2. The filter media 403 are all semi-circular. The semi-circular filter media 403 are spliced ​​into a whole circle by the connecting block 405 and the connecting groove 404. The clearance groove 406 is attached to the surface of the connecting rod 401. The pure water is purified by secondary filtration through the filter media 403 and is discharged from the water plate 402, thereby improving the convenience of replacing the filter media 403 in the filtration and purification device, and avoiding secondary filtration of the liquid when the consumables inside the ultrapure water machine are not replaced in time, so as to ensure the efficiency of filtration and purification.

[0025] In addition, filter media 403 can be made of several different materials stacked together, such as PP filter cotton, activated carbon plate, reverse osmosis membrane and post-activated carbon plate, etc., to perform secondary filtration and purification of liquid.

[0026] Reference Figure 3 A support ring 5 is fixedly connected to the inner wall of the connecting cylinder 1. One side of the support ring 5 is in contact with one side of the water-passing plate 402. Through the support ring 5, one side of the water-passing plate 402 is in contact with one side of the support ring 5, thereby improving the stability of the water-passing plate 402 and the installation mechanism 4.

[0027] Reference Figure 3 A limiting block 6 is fixedly connected to the inner wall of the connecting cylinder 1. Limiting grooves 7 are opened on the surface of the water-passing plate 402 and the surface of the filter material 403. The inner wall of the limiting groove 7 is slidably connected to the surface of the limiting block 6. Through the limiting block 6, the water-passing plate 402 and the filter material 403 are slidably connected to the limiting block 6 through the limiting groove 7, which further increases the stability of the water-passing plate 402 and the filter material 403, and limits the position of the water-passing plate 402 and the filter material 403.

[0028] Reference Figure 1 and Figure 3The bottom of the connecting cylinder 1 is fixedly connected to a liquid guide shell 8, one side of the liquid guide shell 8 is fixedly connected to a first liquid outlet pipe 9, the surface of the liquid guide shell 8 is fixedly connected to a second liquid outlet pipe 11, the surface of the first liquid outlet pipe 9 is fixedly installed with a first control valve 12, and the surface of the second liquid outlet pipe 11 is fixedly installed with a second control valve 13. Through the liquid guide shell 8, which is set in a funnel shape, the liquid discharge efficiency is improved. Before using the filtration and purification device, the second control valve 13 is opened to discharge the stagnant water remaining in the inner cavity of the liquid guide shell 8 through the second liquid outlet pipe 11, ensuring the purity of the subsequently discharged liquid. Then the first control valve 12 is opened, and the first liquid outlet pipe 9 can directly introduce the filtered and purified liquid into the required container.

[0029] Reference Figure 3 A transmission handle 14 is rotatably connected to one side of the sealing cover 2, and a stirring rod 15 is fixedly connected to one side of the transmission handle 14. The surface of the stirring rod 15 is disposed in the inner cavity of the connecting rod 401, and a guide impeller 16 is fixedly connected to one end of the stirring rod 15. The surface of the guide impeller 16 is disposed in the inner cavity of the liquid guiding shell 8. Through the provided guide impeller 16, the transmission handle 14, the stirring rod 15 and the guide impeller 16 are fixedly connected as one unit. When the water guiding efficiency of the filtration and purification device decreases, the transmission handle 14 can be manually rotated to rotate, and the stirring rod 15 can drive the guide impeller 16 to guide the liquid in the inner cavity of the liquid guiding shell 8, thereby increasing the liquid flow rate.

[0030] Reference Figure 4 One end of the first liquid outlet pipe 9 is fixedly connected to a protective cover 17. A baffle 10 is fixedly connected to the inner wall of the protective cover 17. The baffle 10 is made of rubber. By setting the protective cover 17, the protective cover 17 can increase the shielding area of ​​the port of the first liquid outlet pipe 9. The rubber baffle 10 can shield the port of the protective cover 17, so as to avoid external dust and bacteria from contaminating the liquid outlet port of the first liquid outlet pipe 9. The required container can come into contact with the liquid by passing through the baffle 10.

[0031] Working principle: Connecting cylinder 1 is fixedly connected to sealing cover 2. The filtration and purification device is fixedly connected to the required ultrapure water machine through external pipe 3. Filter media 403 can perform secondary filtration on the water filtered in the ultrapure water machine. When replacing filter media 403, connecting cylinder 1 is separated from sealing cover 2, and installation mechanism 4 is fixedly connected to sealing cover 2. All filter media 403 are semi-circular. The semi-circular filter media 403 are spliced ​​into a whole circle by connecting block 405 and connecting groove 404. The clearance groove 406 is attached to the surface of connecting rod 401. Pure water is purified by secondary filtration through filter media 403 and discharged from water plate 402, thereby improving the convenience of replacing filter media 403 in the filtration and purification device and minimizing the need for timely replacement of consumables inside the ultrapure water machine. When changing, the liquid is filtered a second time to ensure the efficiency of filtration and purification. The liquid guide shell 8 is set in a funnel shape to improve the liquid discharge efficiency. Before using the filtration and purification device, the second control valve 13 is opened to discharge the stagnant water remaining in the inner cavity of the liquid guide shell 8 through the second liquid outlet pipe 11 to ensure the purity of the subsequently discharged liquid. Then, the first control valve 12 is opened, and the first liquid outlet pipe 9 can directly introduce the filtered and purified liquid into the required container. The protective cover 17 can increase the shielding area of ​​the port of the first liquid outlet pipe 9. The rubber shield 10 can shield the port of the protective cover 17 to minimize the contamination of the outlet port of the first liquid outlet pipe 9 by external dust and bacteria. The required container can come into contact with the liquid by passing through the shield 10.
