Abstract
Description
Technical Field
[0001] This utility model relates to the field of pure water purification technology, specifically to an ultrapure water purification device. Background Technology
[0002] Ultrapure water refers to water with a resistivity of 18 MΩ*cm (25℃). It contains almost no impurities or minerals and is often used in fields with extremely high water quality requirements, such as electronics, medicine, and scientific research.
[0003] Traditional purification methods use pressure filtration to process the water, but this is not thorough enough in removing the total organic carbon (TOC) content. Furthermore, pure water may contain trace amounts of pathogens. Therefore, ultraviolet photocatalysis can effectively remove trace organic matter from the water, reduce the total organic carbon (TOC) content, and also has a bactericidal and disinfecting effect, killing bacteria, viruses, and other microorganisms in the water.
[0004] Ultraviolet disinfection requires sufficient water flow, while conventional disinfection methods, where the ultraviolet lamp comes into contact with pure water, can easily introduce additional contaminants. Furthermore, after prolonged use, the ultraviolet lamp needs to be replaced and maintained, requiring disassembly, which further contaminates the pipeline. Based on this, this application provides an ultrapure water purification device. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an ultrapure water purification device, which solves the problems of conventional ultraviolet disinfection measures in the prior art, such as the introduction of additional pollutants from contact between ultraviolet lamps and pure water, and the potential for pollution from disassembling pipes for replacement and maintenance.
[0006] The ultrapure water purification device of this utility model includes a base for support and a purification component disposed on the base for treating pure water.
[0007] The base includes a seat body, and a mounting ring is provided on the top of the seat body. The mounting ring is adapted to the purification component.
[0008] The purification component includes a spiral coil, which is adapted to a light-emitting strip mounted on a mounting ring for purifying pure water.
[0009] As a further improvement of this utility model, the spiral coil includes a body, the bottom of which is open, and a light-emitting strip is provided in the open and adapted to the light-emitting strip.
[0010] As a further improvement of this utility model, a water passage is provided on the inner side of the main body, a reflecting prism is provided on the inner side of the water passage, and a transparent covering layer is provided on the outer side of the reflecting prism to wrap the reflecting prism.
[0011] As a further improvement of this utility model, a fixed distance is maintained between one side of the transparent covering layer and the transparent bottom of the body. A light-transmitting layer is provided at this fixed distance, and a light channel is provided at the light-transmitting layer. The light channel is adapted to the light-emitting strip.
[0012] As a further improvement of this utility model, the body of the spiral coil is arranged in a preset angle, and a pipe spacing is provided between adjacent spiral bodies to increase the flow path of pure water.
[0013] As a further improvement of this utility model, both ends of the water passage are provided with a connecting interface, one end of which is provided with an inlet pipe and the other end of which is provided with an outlet pipe. Both the outlet pipe and the inlet pipe are sealed and adapted to the spiral coil through a sealing element.
[0014] As a further improvement of this utility model, the mounting ring includes a ring body, the top of which is provided with a mounting slot, the inner side of which is adapted to the light-emitting strip.
[0015] As a further improvement of this utility model, the light-emitting strip and the ring are both arranged in a preset angle and correspond one-to-one with the spiral coil.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This invention features a mounting ring on the base that is compatible with the purification components. The mounting groove of the mounting ring is fitted with a light-emitting strip, and the light-emitting strip is spirally arranged at a preset angle to the ring body, corresponding one-to-one with the spiral coil. This ensures a tight fit and stability of the entire device structure. It allows ultraviolet light to accurately irradiate the pure water inside the spiral coil, improving energy utilization efficiency, reducing light energy waste, and ensuring long-term stable operation of the device.
[0018] Furthermore, the light strip is installed in the slot of the mounting ring, making it easy to replace and maintain. When the light strip malfunctions or reaches the end of its service life, there is no need to disassemble the entire device; only the light strip on the mounting ring needs to be replaced, reducing the risk of pipeline contamination during maintenance and lowering maintenance difficulty and cost.

[0032] The following illustrations will reveal several embodiments of the present invention. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.
[0033] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
[0034] Please see Figure 1-7Conventional ultraviolet (UV) disinfection methods have some drawbacks in practical applications. UV lamps come into direct contact with pure water, easily introducing additional contaminants, which contradicts the high purity requirements of ultrapure water. Furthermore, the performance of UV lamps gradually declines after prolonged use, necessitating replacement and maintenance. This replacement process requires disassembling the device, which may introduce external contaminants into the pipeline, causing contamination and affecting the quality of the ultrapure water. Therefore, this application provides an ultrapure water purification device, including a support base 1 and a purification component 2 mounted on the base 1, for treating pure water.
[0035] The base 1 includes a base body 11, and a mounting ring 12 is provided on the top of the base body 11. The mounting ring 12 is adapted to the purification component 2.
[0036] The purification component 2 includes a spiral coil 23, which is adapted to a light strip 122 mounted on the mounting ring 12 for purifying pure water.
[0037] The base 11 supports the weight of the purification component 2. The base 11 can be made of high-strength engineering plastics or metal materials, such as stainless steel, which is not only sturdy and durable, but also has a certain degree of corrosion resistance and can adapt to different working environments.
[0038] The mounting ring 12 is located on the top of the base 11. Its main function is to provide an installation interface for the purification component 2 and to fit it. The inner and outer diameters of the mounting ring 12 need to be precisely designed according to the specific dimensions of the purification component 2 to ensure a tight fit between the two. The mounting ring 12 can be fixed to the base 11 by welding or bolting to ensure a firm connection. The inner wall of the mounting ring 12 can be provided with anti-slip textures or rubber sealing gaskets to enhance friction and sealing with the purification component 2.
[0039] The spiral coil 23 is made of corrosion-resistant tubing, such as polytetrafluoroethylene (PTFE) tubing. This tubing has good chemical stability and can resist the erosion of various chemicals, ensuring that there is no secondary pollution of the pure water during the purification process. The design of the spiral coil 23 can increase the flow path and residence time of pure water in the device, giving the pure water more opportunities to come into contact with the ultraviolet light emitted by the light-emitting strip 122, thereby improving the purification effect.
[0040] The light-emitting strip 122 is mounted on the mounting ring 12 and is compatible with the spiral coil 23. The light-emitting strip 122 is composed of ultraviolet (UV) LEDs that emit UV light of specific wavelengths, such as 185nm and 254nm. 185nm UV light can convert oxygen in water into ozone, which has strong oxidizing properties and can further decompose organic matter in the water. 254nm UV light can directly destroy the nucleic acid structure of bacteria, viruses, and other microorganisms, achieving sterilization and disinfection. The light-emitting strip 122 is encapsulated with waterproof sealant to prevent moisture from entering and damaging the LEDs. Heat dissipation fins are also provided on the mounting ring 12 to ensure effective heat dissipation during operation and extend its service life.
[0041] Working principle:
[0042] When pure water needs to be purified, it is introduced into the inlet of the spiral coil 23 through a pipe. As the pure water flows within the spiral coil 23, it is irradiated with ultraviolet light emitted from the light-emitting strip 122. The ultraviolet light decomposes trace organic matter in the water, converting it into carbon dioxide and water, thereby reducing the total organic carbon (TOC) content. It also kills bacteria, viruses, and other microorganisms in the water, achieving the purpose of purifying the water. The treated ultrapure water flows out from the outlet of the spiral coil 23 and enters subsequent usage stages.
[0043] The design of the spiral coil 23 increases the contact time and area between pure water and ultraviolet light, allowing the ultraviolet light to more fully purify the pure water, effectively reducing the total organic carbon (TOC) content in the water, killing microorganisms in the water, and improving the quality of ultrapure water.
[0044] The matching design of the mounting ring 12 and the purification component 2 ensures the precise fit between the light-emitting strip 122 and the spiral coil 23, so that the ultraviolet light can accurately irradiate the pure water inside the spiral coil 23, improving energy utilization efficiency and reducing the waste of light energy.
[0045] The light strip 122 is mounted on the mounting ring 12 for easy replacement and maintenance. When the light strip 122 malfunctions or reaches the end of its service life, it is not necessary to disassemble the entire device; only the light strip 122 on the mounting ring 12 needs to be replaced, reducing the risk of pipeline contamination during maintenance.
[0046] The spiral coil 23 is made of corrosion-resistant polytetrafluoroethylene tube, and the light strip 122 is waterproofly encapsulated, which can effectively resist the erosion of chemical substances and the influence of moisture, extend the service life of the device, and reduce the cost of use.
[0047] The spiral coil 23 includes a body 231, the bottom of which is open, and a light strip 122 is located in the open and adapted to it.
[0048] The inner side of the main body 231 is provided with a water passage 235, and a reflecting prism 236 is provided inside the water passage 235. The outer side of the reflecting prism 236 is covered with a transparent covering layer 237 for wrapping the reflecting prism.
[0049] A fixed gap is maintained between one side of the transparent cover layer 237 and the transparent bottom of the body 231. A light-transmitting layer 234 is provided at the fixed gap, and a light channel 238 is provided at the light-transmitting layer 234. The light channel 238 is adapted to the light-emitting strip 122.
[0050] The body 231 of the spiral coil 23 is spiraled at a preset angle, and a pipe spacing 233 is provided between adjacent spiral bodies 231 to increase the flow path of pure water.
[0051] The body 231 of the spiral coil 23 can be made of a transparent, chemically stable, and strong material, such as quartz glass. This material not only ensures good ultraviolet light transmittance but also resists the corrosion of pure water and any possible chemicals, ensuring that the quality of ultrapure water is not affected during long-term use.
[0052] The bottom of the main body 231 is open, which allows the light-emitting strip 122 to better cooperate with the spiral coil 23. The light-emitting strip 122 can be installed on a special bracket, which is fixed on the mounting ring 12 of the base 11 and can be accurately aligned with the bottom opening of the spiral coil 23. In order to ensure that the ultraviolet light emitted by the light-emitting strip 122 can enter the spiral coil 23 efficiently, an optical lens can be set at the opening to concentrate the light and focus more ultraviolet light into the water passage 235.
[0053] The water passage 235 is the path for pure water to flow. Its inner diameter needs to be designed according to the actual flow requirements. In order to ensure the uniformity of pure water flow in the passage, some guide grooves can be set on the inner wall of the water passage 235 to guide the pure water to flow smoothly.
[0054] The reflecting prism 236 can be composed of multiple equilateral triangular prisms, evenly distributed inside the water passage 235. These prisms are made of high-transmittance optical glass, which can effectively reflect ultraviolet light. The presence of the reflecting prism 236 can change the propagation direction of ultraviolet light, causing the ultraviolet light to be reflected multiple times within the water passage 235, thus increasing the chance of contact between ultraviolet light and pure water.
[0055] The transparent covering layer 237 can be made of transparent plexiglass, which has good light transmittance and a certain degree of flexibility. It can tightly wrap the reflective prism 236 and play a protective role. At the same time, the transparent covering layer 237 can also prevent the reflective prism 236 from directly contacting pure water and avoid contamination or corrosion of the surface of the reflective prism 236.
[0056] The light-transmitting layer 234 can be made of transparent silicone material and fills the fixed gap between the transparent cover layer 237 and the transparent bottom of the body 231. Silicone has good flexibility and light transmittance, can fill the gap, and can play a role in buffering and sealing.
[0057] The light channel 238 is the path for ultraviolet light to enter the water passage 235. It can be achieved by reserving a channel of a specific shape in the light-transmitting layer 234. The shape of the light channel 238 can be designed as a trumpet shape, with the larger opening facing the light-emitting strip 122 and the smaller opening facing the water passage 235. This allows more ultraviolet light to converge into the water passage 235, improving the light energy utilization rate.
[0058] The body 231 of the spiral coil 23 is spiraled at a preset angle. This preset angle can be adjusted according to actual space requirements and pure water flow rate. If the spacing is too large, the device may become too large; if the spacing is too small, it may affect the flow of pure water and the effect of ultraviolet light irradiation. For example, for ultrapure water purification devices with a small flow rate, the pipe spacing 233 can be appropriately reduced; for devices with a large flow rate, the pipe spacing 233 can be appropriately increased.
[0059] By setting up the reflecting prism 236, the ultraviolet light is reflected multiple times in the water passage 235, increasing the contact opportunities and time between the ultraviolet light and the pure water. This allows the ultraviolet light to exert its oxidation and sterilization effects more fully, thereby more effectively reducing the total organic carbon content in the water and killing microorganisms, thus improving the purification effect of ultrapure water.
[0060] The transparent covering layer 237 encloses the reflective prism 236, preventing the reflective prism 236 from directly contacting pure water, thus preventing the reflective prism 236 from being contaminated or corroded, extending the service life of the reflective prism 236, and also ensuring the long-term stable operation of the device.
[0061] The design of the light-transmitting layer 234 and the light channel 238 can guide ultraviolet light into the water-passing channel 235 more efficiently, reduce the loss of ultraviolet light during the propagation process, improve the utilization rate of light energy, and reduce energy consumption.
[0062] The spiral coil 23 is arranged at a preset angle, and a pipe spacing 233 is set between adjacent spiral bodies 231, which effectively increases the flow path of pure water, allowing the pure water to receive ultraviolet light treatment for more time, and further improving the purification quality of ultrapure water.
[0063] Both ends of the water passage 235 are provided with a connection interface 232. One end of the connection interface 232 is provided with a water inlet pipe 21, and the other end of the connection interface 232 is provided with a water outlet pipe 22. The water outlet pipe 22 and the water inlet pipe 21 are both sealed and adapted to the spiral coil 23 through a sealing element 24.
[0064] The mounting ring 12 includes a ring body 121, and a mounting slot 123 is provided on the top of the ring body 121. The inner side of the mounting slot 123 is adapted to the light strip 122.
[0065] The light strip 122 and the ring 121 are both arranged in a preset angle and correspond one-to-one with the spiral coil 23.
[0066] The interfaces 232 at both ends of the water passage 235 are made of high-strength, corrosion-resistant plastic or metal materials, such as stainless steel or polyvinyl chloride (PVC). The design of the interfaces 232 should ensure that they can be tightly connected with the inlet pipe 21 and the outlet pipe 22. Threads or grooves can be provided on the inner wall to facilitate the installation of the seal 24 and to achieve a stable connection.
[0067] Both the inlet pipe 21 and the outlet pipe 22 are made of corrosion-resistant materials, such as stainless steel or silicone tubing. The inlet pipe 21 is used to introduce the pure water to be treated into the water passage 235 of the spiral coil 23. A flow regulating valve can be installed on its exterior to allow operators to control the inlet flow rate according to actual needs. The outlet pipe 22 leads the treated ultrapure water out of the device and can be connected to subsequent storage or use equipment. To facilitate observation of the water flow, the outlet pipe 22 can be made of transparent material, and a flow sensor and water quality monitoring probe can be installed at appropriate locations to monitor the flow rate and water quality of the outlet water in real time.
[0068] The seal 24 is made of rubber or silicone, providing good elasticity and sealing performance. The shape of the seal 24 is designed according to the connection method between the interface 232 and the inlet pipe 21 and outlet pipe 22. For example, for threaded connections, a ring-shaped rubber seal can be used; for groove connections, a silicone gasket can be used. When installing the seal 24, ensure it is correctly positioned and tightly sealed to prevent pure water leakage.
[0069] The ring body 121 is the main body of the mounting ring 12, made of a robust metal material (such as aluminum alloy) or high-strength plastic, with sufficient strength and stability to support the light-emitting strip 122. The surface of the ring body 121 undergoes special treatment, such as anodizing (for aluminum alloy ring body 121) or spraying an anti-corrosion coating (for plastic ring body 121), to improve its corrosion resistance and extend its service life.
[0070] The mounting slot 123 is located at the top of the ring 121, and its shape and size are precisely adapted to the light-emitting strip 122. The inner wall of the slot can be provided with anti-slip texture or elastic clips to ensure that the light-emitting strip 122 will not loosen after installation. To facilitate the installation and removal of the light-emitting strip 122, one end of the slot can be designed to be open, and a guide bevel is provided at the opening to facilitate the smooth insertion of the light-emitting strip 122 into the slot.
[0071] The light-emitting strip 122 and the ring 121 are both spiraled at a preset angle. This preset angle is usually matched with the spiral angle of the spiral coil 23 so that the light-emitting strip 122 can correspond one-to-one with the spiral coil 23, ensuring that the ultraviolet light can be evenly irradiated into the water passage 235 of the spiral coil 23. When installing the light-emitting strip 122, a special positioning tool should be used to ensure that its position is accurate.
[0072] The one-to-one correspondence between the light strip 122 and the spiral coil 23 is very important. It can ensure that the water passage 235 of each spiral coil 23 can be fully irradiated with ultraviolet light. In order to achieve this correspondence, the light strip 122 and the spiral coil 23 must be numbered and marked during the production process, and the corresponding installation must be carried out strictly in accordance with the numbering.
[0073] The inlet pipe 21, outlet pipe 22 and spiral coil 23 are sealed and matched with the sealing element 24, which effectively prevents pure water leakage, ensures the normal operation of the device, and avoids environmental pollution and resource waste caused by water leakage.
[0074] The mounting slot 123 of the mounting ring 12 makes the installation and removal of the light strip 122 convenient and quick, and can firmly fix the light strip 122, ensuring that it will not loosen or shift during operation and ensuring the stability of ultraviolet light irradiation.
[0075] The light-emitting strip 122 is spirally arranged at a preset angle with the ring 121 and corresponds one-to-one with the spiral coil 23, ensuring that the ultraviolet light can evenly and fully irradiate the water passage 235 of the spiral coil 23, thereby improving the oxidation and sterilization effect of ultraviolet light on pure water and thus improving the purification quality of ultrapure water.
[0076] Because of the reasonable design of the connection between the components, the replacement of the water inlet pipe 21 and the water outlet pipe 22, as well as the maintenance of the light strip 122, can be carried out easily, reducing the maintenance cost and difficulty of the device.
[0077] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
