Description

Technical Field

[0001] This utility model relates to the field of water treatment device technology, and more particularly to the field of drinking water sterilization treatment device technology, specifically to a basket-type ultraviolet sterilizer. Background Technology

[0002] Municipal tap water systems commonly employ chemical treatment processes such as chlorine disinfection and ozone oxidation. While these processes can effectively inactivate most pathogenic microorganisms, they also have significant drawbacks: First, chemical disinfectants readily react with organic matter in the water to produce carcinogenic byproducts such as trihalomethanes, posing health risks with long-term consumption. Second, the decay of residual disinfectant concentration in the water supply network may lead to secondary pollution risks, especially in older pipes or end-point water supply areas. Third, the odor problem caused by residual chlorine has a long-term impact on the taste of drinking water.

[0003] In recent years, ultraviolet (UV) disinfection technology has been introduced into the water treatment field due to its broad-spectrum sterilization and lack of chemical residue. However, existing applications have significant limitations: most UV devices are only installed at the treatment terminal inside water plants, failing to cover microorganisms that proliferate in the water distribution process after the water leaves the plant; a few household UV purifiers require users to install and maintain them themselves, resulting in low adoption rates and an inability to guarantee the safety of water for the entire community. More importantly, traditional UV systems have poor adaptability to sudden changes in water flow, making it difficult to maintain stable disinfection efficiency under pressure fluctuations in complex pipe networks.

[0004] Therefore, there is an urgent need for an ultraviolet disinfection solution that can be deeply integrated with the municipal water supply system and can completely block microbial contamination, so as to overcome the limitations of existing technologies on water quality fluctuations and operation and maintenance costs while ensuring sterilization rate. Utility Model Content

[0005] To address the disinfection issue of drinking water, this application provides a basket-type ultraviolet sterilizer that can be deeply integrated with municipal water supply systems and can completely block microbial contamination. This invention offers high installation flexibility and is not limited by installation location. By installing this invention on the main pipeline of the municipal water supply system, such as inside a regulating pipe, it can indiscriminately disinfect and sterilize the supplied tap water, further reducing the microbial content in drinking water and improving its quality. This invention employs modular, sealed integration technology, allowing for individual maintenance and installation of the disinfection components without requiring water supply network shutdowns or pressure cuts, resulting in high practicality and low subsequent maintenance costs.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: A basket-type ultraviolet sterilizer includes a water pipe with at least one inlet and one outlet. A sterilization device is installed inside the water pipe. The sterilization device is detachably and sealed inside the water pipe. The sterilization device has multiple ultraviolet sterilization modules installed on it. Each ultraviolet sterilization module includes a quartz tube sealed inside the water pipe and an ultraviolet lamp installed in the quartz tube.

[0007] Preferably, the ultraviolet disinfection module and the water pipe are detachably and sealed together by a flange assembly. The flange assembly includes a first flange integrally connected to the water pipe and a second flange for supporting the ultraviolet disinfection module. The second flange is provided with a plurality of mounting holes for detachable and sealed installation of the quartz tube. A filter screen for accommodating the quartz tube is also connected to one end of the second flange near the water pipe. A base plate is fixedly connected to the free end of the filter screen. The base plate has support holes corresponding to the mounting holes for constraining the bottom of the quartz tube.

[0008] To better secure the quartz tube and prevent it from breaking due to external impacts from water flow and pressure fluctuations, preferably, a shock-absorbing pad or an elastic material for providing damping constraints is provided on the side of the support hole near the quartz tube.

[0009] To ensure that water and pressure can be cut off without interrupting the process when replacing the UV lamp, it is necessary to ensure that the quartz tube and the second flange remain sealed. At the same time, the UV lamp can be easily removed and replaced. As a feasible, practical and preferred solution, the outer wall of the quartz tube is fitted with a first connector that is detachably and sealed to the mounting hole. The first connector is detachably connected to a second connector for fixing the UV lamp.

[0010] To ensure compatibility between different types of ultraviolet lamps and this invention, preferably, the second connector is also provided with a sealing plug for sealing the end of the ultraviolet lamp or the wiring harness connected to the ultraviolet lamp.

[0011] To ensure both the convenience of detachable connection and modular installation, as well as the reliability of airtight sealing, preferably, a shock-absorbing sealing head is installed between the quartz tube and the first connector, and a sealing ring is provided between the first connector and the second connector.

[0012] To disinfect drinking water flowing through the pipes over a larger area and more efficiently, preferably, the length direction of the ultraviolet disinfection module is aligned with the length direction of the water pipe. Beneficial effects

[0013] 1. This utility model, by being integrated into the municipal water supply network, can disinfect and sterilize all drinking water flowing through the network with ultraviolet light, further reducing the microbial content in drinking water and improving the health quality of drinking water. Compared with the existing water storage tank sterilization, the sterilization blind spot is smaller.

[0014] 2. This utility model adopts a modular structure design, which takes into account the convenience of early installation and later operation and maintenance, while also taking into account the airtightness requirements in the working state; when replacing the only potentially damaged ultraviolet lamp, the ultraviolet lamp can be directly removed through the original airtight ultraviolet disinfection module structure design without any operation on the water supply network. The design allows the replacement of the faulty ultraviolet lamp without stopping the operation of other ultraviolet lamps. Attached Figure Description

[0032] This embodiment provides a basket-type ultraviolet sterilizer, the structure of which is as follows: Figures 1-9 As shown, the device includes a water pipe 1, which has at least one inlet 11 and an outlet 12. A disinfection device 2 is also installed inside the water pipe 1. The disinfection device 2 is detachably and sealed inside the water pipe 1. The disinfection device 2 is equipped with multiple ultraviolet disinfection modules 22. Each ultraviolet disinfection module 22 includes a quartz tube 221 sealed inside the water pipe 1 and an ultraviolet lamp 222 installed in the quartz tube 221.

[0033] Working and structural principles: See Figure 1 The isometric view of the sterilizer shown, and Figure 8 and Figure 9 The ultraviolet disinfection module 22 shown is installed in the municipal water supply network. Depending on actual needs, the ultraviolet disinfection module 22 can be installed anywhere in the drinking water network. This embodiment merely provides a structural solution. Since ultraviolet (UV) disinfection technology is a mature existing technology, this embodiment simply provides a device that better utilizes UV disinfection technology to achieve its disinfection and sterilization effects, deeply integrating it with the municipal water supply network. During use, because the ultraviolet disinfection module 22 is always immersed in the water pipe 1, after being powered on, the ultraviolet light emitted by the ultraviolet disinfection module 22 irradiates the drinking water in the water pipe 1, killing bacteria in the drinking water and achieving disinfection and sterilization. Since the ultraviolet lamp 222 in the ultraviolet disinfection module 22 is inserted into the quartz tube 221, and the quartz tube 221 is sealed and connected to the water pipe 1 to form an integrated structure, the ultraviolet lamp 222 can be freely inserted and replaced, facilitating replacement without being affected by the water pressure in the water pipe 1, thus improving convenience. Due to the limited diameter of water pipe 1, the built-in ultraviolet disinfection module 22 can achieve sterilization without dead angles. Compared with existing water tank sterilization, it eliminates sterilization blind spots, shortens the irradiation distance, and in a relatively narrower environment, the reflection of ultraviolet rays further increases the intensity / density of ultraviolet rays, thereby improving sterilization efficiency. Example

[0034] Having explained the working principle of this utility model, this embodiment further optimizes the structure based on Embodiment 1, aiming to improve and enhance aspects such as structural stability, ease of operation and maintenance, and compatibility with consumable components. Specifically, the ultraviolet disinfection module 22 and the water pipe 1 are detachably connected by a flange assembly in a sealed manner. See [link to relevant documentation]. Figure 1 As shown, the flange assembly includes a first flange 13 integrally connected to the water pipe 1 and a second flange 21 for supporting the ultraviolet disinfection module 22. The second flange 21 is provided with multiple mounting holes for detachable and hermetically sealed installation of the quartz tube 221. A filter screen 23 for accommodating the quartz tube 221 is also connected to the end of the second flange 21 near the water pipe 1. (See Figure 1 for details.) Figure 8 and Figure 9 As shown, a base plate 231 is fixedly connected to the free end of the filter screen 23. The base plate 231 has support holes 232 corresponding to the mounting holes for constraining the bottom of the quartz tube 221. The filter screen 23 has three functions: First, it prevents sand and gravel in the drinking water from contacting the quartz tube 221, avoiding rapid impact of sand and gravel on the quartz tube 221 at high flow rates, which would negatively affect the lifespan of the quartz tube 221 over a long period. Second, the filter screen 23 and the base plate 231 serve as the physical structure supporting the quartz tube 221, allowing the quartz tube 221 to be designed to be longer to cover a longer axial distance. This increases the contact time with water at the same flow rate, thereby improving the actual sterilization effect. Thirdly, the mesh of filter 23 allows ultraviolet light to enter the space between water pipe 1 and filter 23 for sterilization. At the same time, the inner wall of filter 23 provides a physical interface for ultraviolet light reflection, resulting in higher ultraviolet light intensity / density in the space inside filter 23 and better sterilization effect.

[0035] To better secure the quartz tube 221 and prevent it from breaking due to external impacts from water flow and pressure fluctuations, in this embodiment, as follows: Figure 6 As shown, the support hole 232 near the quartz tube 221 is also provided with a shock-absorbing pad or an elastic material for providing damping constraint, which is not shown in the figure.

[0036] To ensure that water and pressure can be maintained without interrupting the process when replacing the UV lamp 222, it is necessary to ensure that the quartz tube 221 and the second flange 21 remain sealed. Simultaneously, the UV lamp 222 must be easily accessible for removal and replacement. Therefore, as a feasible, practical, and preferred solution, such as... Figure 7 As shown, the outer wall of the quartz tube 221 is fitted with a first connector 225 that is detachably and sealed to the mounting hole. The first connector 225 is detachably connected to a second connector 226 for fixing the ultraviolet lamp 222.

[0037] In order to ensure that different models of ultraviolet lamps 222 are compatible with this utility model, in this embodiment, the second connector 226 is also provided with a sealing plug 227 for sealing the end of the ultraviolet lamp 222 or the wiring harness connected to the ultraviolet lamp 222.

[0038] In order to balance the convenience of detachable connection and modular installation with the reliability of airtight sealing, in this embodiment, a shock-absorbing sealing head 223 is installed between the quartz tube 221 and the first connector 225, and a sealing ring 224 is provided between the first connector 225 and the second connector 226.

[0039] In order to disinfect drinking water flowing through water pipe 1 more efficiently over a larger area, in this embodiment, the length direction of the ultraviolet disinfection module 22 is consistent with the length direction of water pipe 1.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
