Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to an integrated water purification and filtration device. Background Technology

[0002] Current water purification system designs typically consist of a combination of multiple independent devices, including but not limited to pretreatment units, depth filtration units, and ultraviolet purification units. These functional modules often require individual installation and are connected and coordinated through a series of pipes. The diverse interface types between these devices make the installation process quite cumbersome and the layout relatively complex. This complexity not only increases the difficulty of pipework construction and maintenance but also makes the system prone to leaks or decreased purification efficiency due to improper installation. Furthermore, the need for multiple devices to be distributed across the system occupies a significant amount of space, making this traditional water purification system unsuitable for space-constrained residential, office, or mobile environments.

[0003] Furthermore, because the coordination between modules in traditional water purification systems is not close, the filtrate suffers from excessively long paths and high energy consumption during transmission between units. This design hinders the achievement of rapid and efficient integrated water purification, thus impacting the overall system performance and efficiency.

Prior Art 1 integrates multiple water purification processes, including filtration, disinfection, heating, and cooling. Specifically, it includes a filtered water storage tank, a purified water filter pipe, a filtered water disinfection tank, a cooling device, and a heating device. Through multifunctional components mounted on the same frame, it achieves coordinated processing throughout the entire water purification process. The device is equipped with casters and brakes for easy movement and fixation, offering strong practicality and convenience, suitable for high-efficiency water purification needs in various situations. Although Prior Art 1 integrates multiple water purification functions, the overall structure still consists of multiple stacked independent components, resulting in complex connecting pipes and a large device size. It has not yet achieved a truly highly integrated design and fails to completely solve the core problems of cumbersome installation and large space occupation inherent in prior art.

[0032] Example 1

[0033] Please see Figure 1This utility model provides an integrated water purification and filtration device. Modern water purification systems typically consist of multiple independent devices, including but not limited to pretreatment devices, depth filtration devices, and ultraviolet purification devices. These functional modules usually need to be installed individually and connected and work together via a series of pipes. Due to the diverse interface types between these devices, the installation process of the entire water purification system becomes quite cumbersome, and the layout is relatively complex. This complexity not only increases the difficulty of pipe construction and maintenance but also easily leads to system leaks or a decrease in purification efficiency due to improper installation. Furthermore, since multiple devices need to be distributed, this occupies a large amount of space, making this traditional water purification system unsuitable for space-constrained residential, office, or mobile environments.

[0034] Therefore, this utility model provides an integrated water purification and filtration device. By combining the various modules via a frame 100, it functions as a single unit during use and transportation, thus simplifying the installation process and reducing system complexity. This integrated design reduces the number of pipe connections 500, avoiding the cumbersome wiring during installation. Simultaneously, because the modules are compactly combined, the space occupied by the entire device is greatly reduced, making it more suitable for space-constrained environments. Furthermore, this design facilitates transportation and storage, providing greater convenience for users.

[0035] Please see Figure 1 In this embodiment, the water purification filtration device includes a frame 100, a filter assembly 200, and a purification assembly 300. The filter assembly 200 is disposed on the frame 100 and has a first filter chamber 210 and a second filter chamber 200. The first filter chamber 210 and the second filter chamber 200 are respectively provided with a first filter element 211 and a second filter element 221. The purification assembly 300 is disposed on the frame 100 and has a purification chamber 310 and a purification lamp tube inside the purification chamber 310. The first filter chamber 210 and the second filter chamber 200 are connected through the first filter element 211. The second filter chamber 200 is provided with a first water outlet 215, and the purification chamber 310 is provided with a first water inlet 311. The first water outlet 215 and the first water inlet 311 are connected through a pipe 500, and the filtrate filtered by the filter assembly 200 is sent to the purification assembly 300 for purification.

[0036] In use, the user simply connects the water source to the inlet of the first filtration chamber 210. The water first undergoes preliminary filtration through the first filter element 211, removing larger impurities and particles. Subsequently, the pre-filtered water enters the second filtration chamber 200, where it undergoes further filtration through the second filter element 221 to remove minute impurities, bacteria, and some chemicals. After secondary filtration, clean water flows out from the first outlet 215 of the second filtration chamber 200 and enters the first inlet 311 of the purification chamber 310 through the connected pipe 500. Inside the purification chamber 310, purification lamps emit light of specific wavelengths to kill or decompose residual harmful substances in the water, thereby improving water quality and ensuring that the final output is pure and safe drinking water.

[0037] Further, please see Figure 2 and Figure 4 The first filter element 211 includes a filter section 212 and a guide pipe 213 communicating with the filter section 212, and the guide pipe 213 connects the first filter chamber 210 and the second filter chamber 200. The filter section 212 also has a guide plate 214 extending into the guide pipe 213. In use, raw water enters the first filter chamber 210 through the second inlet 216, initially flowing around the periphery of the filter section 212, where larger impurities and particles are trapped. Next, the water flows through the fine pores inside the filter section 212, further removing suspended solids and tiny impurities. To optimize the water flow path and improve filtration efficiency, the guide plate 214 is located inside the filter section 212 and extends into the guide pipe 213. The presence of the guide plate 214 allows for a more even distribution of water flow when entering the guide pipe 213, avoiding problems such as insufficient filtration or excessive wear of the filter element caused by excessively large or small local water flows. Guided by the baffle plate 214, the water flows smoothly into the guide pipe 213 and finally flows out from the other end of the guide pipe 213 into the second filter chamber 200 to continue the subsequent filtration and purification process. This design not only improves filtration efficiency but also extends the service life of the filter element, providing users with a more stable and efficient water purification experience.

[0038] Further, please see Figure 3The first filter chamber 210 has a second water inlet 216 at its top, and a first pressure relief port 217 and a second pressure relief port 218 at its bottom ends. During use, since the first filter chamber 210 is the first stage of filtration, filter residue may accumulate near the filter section 212 and the guide pipe 213. When the filter residue accumulates significantly, it may increase the difficulty of water flow, leading to increased water pressure and preventing normal filtration. To address this, a first pressure relief port 217 and a second pressure relief port 218 are provided. When the water pressure in the first filter chamber 210 exceeds a preset safety value, either the first pressure relief port 217 or the second pressure relief port 218 opens, allowing the accumulated filter residue or filtrate to be discharged, thus relieving pressure and preventing damage to the filter element or the entire water purification equipment due to excessive water pressure. This design not only improves the safety of the equipment, but also ensures that users can promptly detect and take measures when the filter becomes clogged or needs cleaning, avoiding equipment failure or damage caused by water pressure issues, and further enhancing the user experience and equipment reliability.

[0039] Further description: In the structural design of the first filter chamber 210, a cleaning end is specially provided at the end furthest from the second filter chamber 200. This cleaning end design allows the first filter element 211 to be installed inside the first filter chamber 210 through its own cleaning end portion. This design allows the user to easily replace the first filter element 211 or perform a thorough cleaning of the first filter chamber 210 to restore its filtration efficiency when the service life of the first filter element 211 reaches a certain level or when there is severe clogging inside the first filter chamber 210, by opening this cleaning end.

[0040] In this embodiment, the first filter element 211 is designed as a porous activated carbon filter element, known for its excellent adsorption performance, effectively removing organic matter and some chemicals from the water. The second filter element 221 is a PP filter element with multiple layers of stacked filter cakes. This type of filter element is widely used for its good physical filtration performance, capable of intercepting suspended particles and some microorganisms in the water. In the actual filtration process, the water first undergoes preliminary chemical purification through the first filter element 211, and then undergoes further physical filtration through the second filter element 221, thereby ensuring that the final output water is both safe and pure.

[0041] This filtration sequence is suitable for raw water with primarily dissolved contaminants and low suspended solids content, such as municipal tap water, rainwater, or pre-treated low-turbidity water. Porous activated carbon, as the first-stage filter, efficiently adsorbs residual chlorine, organic pollutants (such as pesticides and VOCs), and odor-causing substances, improving the chemical safety of the water. The water then flows through a PP filter, intercepting fine carbon powder or residual particles that may detach from the activated carbon, ensuring the physical cleanliness of the effluent. The advantage of this sequence is that it prioritizes the chemical adsorption function of the activated carbon while preventing premature clogging of the PP filter due to large particles, thus extending the overall filter life. It is particularly suitable for drinking water purification scenarios with strict requirements for taste and odor.

[0042] Further, please see Figure 1 In this embodiment, a pressure relief assembly 400 is also included, mounted on the frame 100. The first pressure relief port 217 and the second pressure relief port 218 are both connected to the pressure relief assembly 400 via pipes 500. The pressure relief assembly 400 is equipped with a pressure relief drain port 410. This allows excess pressure to be released promptly through the pressure relief drain port 410 when the internal pressure of the equipment abnormally increases, preventing damage to the equipment due to excessive pressure. Simultaneously, the design of the pressure relief assembly 400 ensures the stability of the water flow during the filtration process, preventing pressure fluctuations from affecting the filtration effect. Furthermore, the pressure relief drain port 410 can also serve as a discharge outlet during equipment maintenance, facilitating cleaning and upkeep, and improving the overall reliability and service life of the equipment.

[0043] Further, please see Figure 2 The second filter element 221 is installed inside the second filter chamber 200. Its main function is to further purify the filtrate flowing out of the first filter chamber 210 to ensure the purity of the filtrate. A dedicated cleaning port 222 is provided at the end of the second filter chamber 200 opposite to the first filter chamber 210. This cleaning port 222 serves a dual purpose: firstly, it allows the user to easily replace the second filter element 221 when needed to maintain the efficient operation of the filtration system; secondly, it also facilitates cleaning of the second filter chamber 200, ensuring the cleanliness and hygiene of the entire filtration system, thereby extending the service life of the equipment and guaranteeing the filtration effect.

[0044] Furthermore, the first water inlet 311 is located at the top of the purification chamber 310; the purification chamber 310 is also provided with a second water outlet 312 at the end away from the first water inlet 311.

[0045] Further, please see Figure 3The purification lamp tube includes a first lamp tube 321 and a second lamp tube 326; the first lamp tube 321 and the second lamp tube 326 are fixedly connected in the purification chamber 310. The first lamp tube 321 includes a first mounting end 322 and a second mounting end 323, and a plurality of UV lamp strips 324 disposed between the first mounting end 322 and the second mounting end 323; the plurality of UV lamp strips 324 are arranged at intervals; a protective cover 325 is also provided between the first mounting end 322 and the second mounting end 323, and the protective cover 325 seals the plurality of UV lamp strips 324 within the protective cover 325. This can effectively prevent the UV lamp strips 324 from being directly exposed to the external environment, avoid damage or contamination to the UV lamp strips 324, and thus extend their service life. At the same time, the protective cover 325 can also protect the lamp tube and improve the safety of use. Furthermore, the fixed connection between the first lamp 321 and the second lamp 326 ensures their stability and reliability within the purification chamber 310, allowing UV light to evenly illuminate every corner of the purification chamber 310 and improving the purification effect. The spaced arrangement of several UV lamp strips 324 saves energy and reduces operating costs while maintaining purification effectiveness.

[0046] Further, please see Figure 5 The UV lamp strips 324 are spaced apart via a first mounting end 322 and a second mounting end 323, and multiple strips are arranged to cover the entire circumference of the filtrate. The lamp strips are arranged parallel to each other. When the UV lamps are installed in parallel, all lamps are arranged in a short array, with uniform spacing and parallel to the water flow direction. The main advantage of this layout is that it provides a uniform and stable ultraviolet radiation field, ensuring that the UV dose received by each part of the water flow is consistent, making it particularly suitable for treating water with stable flow and low turbidity. The parallel arrangement of the lamps is compact, facilitating maximum irradiation area within a limited space, while simplifying the design and sealing of the protective cover 325 and reducing maintenance difficulty. Furthermore, the rectangular layout of the lamps provides better heat dissipation, preventing localized overheating and extending the lifespan of the UV lamps, making it suitable for water purification systems requiring long-term continuous operation.

[0047] Furthermore, the first lamp tube 321 and the second lamp tube 326 have the same structural configuration.

[0048] Furthermore, both the first filter chamber 210 and the second filter chamber 200 are equipped with pressure monitors 420 to detect the pressure in both chambers, preventing equipment damage or poor purification performance due to excessive pressure. Real-time pressure monitoring allows for timely detection and resolution of potential problems, ensuring the smooth operation of the purification process. Simultaneously, the pressure monitors 420 provide data support for equipment maintenance, helping users better understand the equipment's operating status, develop reasonable maintenance plans, and extend the equipment's lifespan. In addition, the pressure monitors 420 enhance equipment safety and stability, providing more reliable protection for users' production and daily lives.

[0049] Example 2

[0050] Please see Figure 2 This utility model provides an integrated water purification and filtration device. In embodiment 1, the filtration sequence is from the first filtration chamber 210 to the second filtration chamber 200. This setup is suitable for raw water with mainly dissolved pollutants and low suspended solids content. However, it cannot filter raw water with high turbidity, high suspended solids, or colloidal substances. Replacing the purification and filtration setup is quite troublesome. Therefore, this embodiment provides a structure that reverses the purification and filtration device in embodiment 1 to treat raw water with high turbidity, high suspended solids, or colloidal substances.

[0051] In this embodiment, a specific installation method is adopted, where the cleaning port 222 is used as the raw water inlet. This ensures that the raw water can smoothly enter the entire system. Next, the first pressure relief port 217 is connected to the first water inlet 311 of the purification component 300. This connection method ensures that the system can effectively release pressure during the purification process, thereby guaranteeing the stability and safety of the entire purification process. Furthermore, the first water outlet 215 is connected to one of the pressure relief ports of the pressure relief component 400. This connection method achieves reverse installation of the equipment, enabling more efficient water purification during operation.

[0052] When using this equipment, raw water first enters through the cleaning port 222 and then flows into the first filtration chamber 210. In the first filtration chamber 210, the raw water is filtered by the first filter element 211. This process is crucial because the first filter element 211 effectively removes impurities and contaminants from the water. The water filtered by the first filter element 211 flows back into the filtration section 212 through the guide pipe 213. In design, the diameter of the filtration section 212 is larger than the diameter of the guide pipe 213, allowing the guide pipe 213 to be fitted inside the filtration section 212. The advantage of this structural design is that the filtrate, after being filtered by the filtration section 212, is discharged through the first pressure relief port 217. Finally, this pre-purified filtrate is discharged into the purification assembly 300 for further purification to ensure that the final output water quality meets the expected standards and requirements.

[0053] Further, please see Figure 3 and Figure 6 The first lamp tube 321 includes a first mounting end 322 and a second mounting end 323, and a plurality of UV lamp strips 324 disposed between the first mounting end 322 and the second mounting end 323; the plurality of UV lamp strips 324 are arranged at intervals; a protective cover 325 is also provided between the first mounting end 322 and the second mounting end 323, and the protective cover 325 seals the plurality of UV lamp strips 324 inside the protective cover 325.

[0054] In this embodiment, the UV lamp strip 324 is inclined at a certain angle between the first mounting end 322 and the second mounting end 323; the inclined installation method arranges the UV lamps at a certain angle to form a conical radiation structure, so that the direction of ultraviolet irradiation and the water flow form an intersecting path. The core advantage of this design is that it can enhance the turbulence effect of the fluid and avoid dead zones in the water flow, which is especially suitable for treating highly turbid or viscous liquids.

[0055] Because of the tilted lamp tube, the filtrate forms a vortex as it passes through, increasing the contact between contaminants and UV light, thus improving sterilization efficiency. The conical layout also reduces the deposition of suspended solids on the lamp tube surface, lowering the risk of scaling. However, this installation method places high demands on the sealing and structural strength of the protective cover 325, and may increase energy consumption. It is more suitable for intermittent operation or scenarios requiring enhanced disinfection effects, such as wastewater treatment, industrial wastewater reuse, or emergency water purification equipment.

[0056] Furthermore, the first lamp tube 321 and the second lamp tube 326 have the same structural configuration.

[0057] The filtration sequence in this embodiment is designed to better suit the treatment of raw water with high turbidity, high levels of suspended solids, or colloidal substances, such as river water, well water, or industrial wastewater. The PP filter cartridge, as the first stage, effectively traps large particles such as silt, rust, and algae, preventing rapid clogging of the pores of the subsequent activated carbon filter cartridge and thus protecting its adsorption capacity. The post-activated carbon filter further removes dissolved pollutants (such as heavy metals and organic matter), improving water purity. The core of this design lies in distributing the load on the activated carbon through the mechanical filtration of the PP filter cartridge. This makes it particularly suitable for environments with large fluctuations in water quality or high concentrations of suspended solids, such as outdoor water purification equipment or industrial pretreatment systems, balancing filtration efficiency and economy.

[0058] Furthermore, the filter assembly 200 of the water purification filtration device is installed in reverse, so that when the raw water is filtered, it first passes through the second filter chamber 200 for filtration, then enters the first filter chamber 210 through the guide pipe 213 for filtration, and then connects to the inlet of the purification assembly 300 through the pressure relief port. This allows the water to be filtered twice by different filter elements, thus more thoroughly removing various impurities and harmful substances from the water. This reverse installation design provides users with more choices, allowing them to select a more suitable filtration sequence based on the initial water quality of the source to achieve the best filtration effect. At the same time, this design also increases the flexibility and practicality of the water purification filtration device, enabling it to adapt to more different usage scenarios and needs.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
