Description

Technical Field

[0001] This utility model relates to the field of pure water treatment technology, specifically to a pure water purification device. Background Technology

[0002] The demand for high-purity water is increasing in modern industrial and medical applications. The preparation of pure water typically involves multiple steps, including pretreatment, reverse osmosis (RO), and electrodeionization (EDI). Among these, preliminary water purification is crucial. Activated carbon filtration, as an effective means of removing organic matter, residual chlorine, and other impurities from water, is widely used in various water treatment systems.

[0003] While existing activated carbon filters perform excellently in removing organic matter and residual chlorine, a significant problem exists in practical operation: uneven influent water distribution. Because current activated carbon filter designs fail to adequately consider the importance of uniform water flow distribution, significant differences in water flow velocity occur in different areas of the activated carbon layer. This unevenness not only affects the overall adsorption efficiency of the activated carbon but can also lead to localized rapid saturation while other areas remain underutilized. Particularly in high-flow-rate areas, activated carbon easily reaches saturation quickly, while activated carbon in low-flow-rate areas may not be fully utilized. This not only limits the effective lifespan of the activated carbon but also increases operating costs and maintenance frequency. These issues directly affect the stability and effluent quality of the entire pure water preparation system, preventing the activated carbon filter from fully realizing its actual effectiveness. Utility Model Content

[0004] The purpose of this invention is to provide a pure water purification device to solve the problems mentioned in the background art, such as uneven water distribution in activated carbon filters during actual operation, which leads to low adsorption efficiency and shortened service life of activated carbon.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pure water purification device, comprising an activated carbon filter body, wherein a composite filtration component is provided inside the activated carbon filter body, a dynamic distribution ring is provided at the upper end of the activated carbon filter body, a servo motor is installed at the upper end of the outer side of the activated carbon filter body, and the dynamic distribution ring is provided with multiple upper diversion plates, middle turbulence plates and lower diversion plates distributed circumferentially, which together constitute a three-dimensional dynamic diversion mechanism.

[0006] Preferably, the inner end of the upper diverter plate is fixed to the inner wall of the upper end of the dynamic distribution ring, and the outer ends of the upper diverter plate are inclined upward together, forming an angle of 20°-45° with the horizontal plane.

[0007] Preferably, the upper diversion plate is provided with an overflow opening, and the overflow opening on the upper diversion plate is provided with staggered guide baffles.

[0008] Preferably, the inner wall of the dynamic distribution ring is surrounded by a plurality of threaded posts, and the inner end of the middle layer spoiler is provided with a threaded rotating hole that matches the structure of the threaded posts, and the top of the middle layer spoiler is an arc-shaped surface structure.

[0009] Preferably, the outer ends of the bottom flow divider plate are inclined downwards to form an angle of 30°-45° with the horizontal plane, and a number of fluid guiding protrusions are evenly distributed on the bottom wall of the bottom flow divider plate.

[0010] Preferably, the upper flow divider, the middle flow deflector, and the lower flow divider are all uniformly distributed in a circumferential shape inside the dynamic distribution ring, and the dynamic distribution ring is located directly above the composite filter assembly.

[0011] Compared with existing technologies, the beneficial effects of this invention are as follows: This pure water purification device can optimize the inlet water distribution to ensure that the water flow is evenly distributed in the activated carbon layer, significantly improving adsorption efficiency and water quality stability, while extending the service life of the activated carbon and reducing operating costs and maintenance frequency. Through the design of a dynamic distribution ring and its internal upper, middle, and lower flow divider plates, the device achieves multi-level guidance and dispersion of the water flow, effectively avoiding the problem of localized rapid saturation.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: a pure water purification device, including an activated carbon filter body 1. The activated carbon filter body 1 has an inlet and an outlet at its top and bottom, respectively. The activated carbon filter body 1 contains a composite filter assembly 2, which includes multiple layers of filter media of different materials and pore sizes. From top to bottom, it consists of a quartz sand support layer, a high-density activated carbon layer, and a nano-ceramic microfiltration layer. Each layer is separated and fixed by nested stainless steel mesh plates, forming a modular structure that can be disassembled. The upper interior of the activated carbon filter body 1 has a dynamic distribution ring 3, and the upper exterior of the activated carbon filter body 1 is equipped with a servo motor 4. The dynamic distribution ring 3 has multiple circumferentially distributed... The upper diversion plate 31, the middle baffle plate 32, and the bottom diversion plate 33 together constitute a three-dimensional dynamic diversion mechanism. In use, the activated carbon filter body 1 is driven by a servo motor 4 to rotate the dynamic distribution ring 3, causing the upper diversion plate 31, the middle baffle plate 32, and the bottom diversion plate 33 to work together. This ensures that the water entering the activated carbon filter body 1 is first evenly dispersed at a specific angle by the upper diversion plate 31, then further guided by the middle baffle plate 32 to form a complex flow path, ensuring uniform distribution of the water flow throughout the activated carbon layer. Finally, the bottom diversion plate 33 guides the water flow to the composite filter assembly 2. This multi-layered, multi-directional water flow control method effectively avoids the problem of localized rapid saturation and improves the efficiency of activated carbon. The overall adsorption efficiency ensures the stability and consistency of water quality. Simultaneously, the more uniform water flow distribution not only extends the service life of activated carbon but also reduces operating costs and maintenance frequency. This solves the problems of low activated carbon utilization, frequent replacement, and maintenance caused by uneven influent water distribution in existing technologies, thus significantly improving the stability and effluent quality of the entire pure water preparation system. The inner end of the upper diversion plate 31 is fixed to the inner wall of the upper end of the dynamic distribution ring 3, and the outer ends of the upper diversion plate 31 are inclined upwards, forming an angle of 20°-45° with the horizontal plane. This structure allows the water flow entering the dynamic distribution ring 3 to be guided and dispersed by the upper diversion plate 31, causing the water flow to diffuse at a wider angle, thereby avoiding direct water flow... The localized high-pressure areas created by the impact on the activated carbon layer ensure uniform water flow distribution throughout the entire activated carbon layer. The upper distribution plate 31 is equipped with overflow openings, and these openings contain staggered guide baffles 3101. This structure allows for initial dispersion of the water flow through the overflow openings as it passes through the upper distribution plate 31, and further refines the water flow path through the staggered arrangement of the guide baffles 3101. This ensures that the water flow is more evenly and meticulously dispersed after entering the dynamic distribution ring 3. This not only effectively reduces the direct impact force of the water flow, preventing excessive localized erosion of the activated carbon layer, but also increases the turbulence of the water flow, promoting more efficient contact between water molecules and activated carbon, thereby improving adsorption efficiency.The inner wall of the dynamic distribution ring 3 is surrounded by several threaded posts 34, and the inner end of the middle layer baffle 32 is provided with a threaded rotating hole that matches the structure of the threaded posts 34. The top of the middle layer baffle 32 is an arc-shaped surface structure. The middle layer baffle 32 with this structure can be adjusted and fixed at different angles on the threaded posts 34 through the threaded rotating hole to form a variety of postures to adapt to different water flow conditions and optimize the water flow path. This adjustable design allows the middle layer baffle 32 to flexibly adjust its position according to actual needs, thereby more effectively guiding and dispersing the water flow and ensuring the uniform distribution of the water flow in the entire activated carbon filter body 1. The top arc-shaped surface structure further helps to reduce water flow resistance and promote smooth water flow transition, avoids the generation of turbulence, and improves the efficiency of water flow. The outer ends of the bottom flow divider 33 are inclined downwards, forming an angle of 30°-45° with the horizontal plane, and several flow points are evenly distributed on the bottom wall of the bottom flow divider 33. The body-guiding protrusion 3301, through its bottom-level diversion plate 33, further guides the water flow, after being processed by the upper-level diversion plate 31 and the middle-level baffle plate 32, to the surface of the activated carbon layer of the composite filter assembly 2. This ensures that the water flow enters the filtration area in a more uniform and stable manner. Simultaneously, the fluid-guiding protrusion 3301 generates a local vortex effect as the water flow passes through, enhancing the lateral diffusion capacity of the water flow and further optimizing the hydraulic distribution. This avoids "short-circuiting" phenomena and local overload problems caused by concentrated water flow. The upper-level diversion plate 31, the middle-level baffle plate 32, and the bottom-level diversion plate 33 are all uniformly distributed in a ring shape within the dynamic distribution ring 3, which is located directly above the composite filter assembly 2. This structure, through three layers of diversion and baffle elements with different functions symmetrically arranged around the central axis, guides, disperses, and regulates the water flow entering the activated carbon filter body 1 step by step under the action of the dynamic distribution ring 3, forming a multi-level, all-round water flow distribution mode.

[0018] Working Principle: When using this pure water purification device, the water to be treated first enters the interior through the inlet at the top of the activated carbon filter body 1, and then flows into the dynamic distribution ring 3 located directly above the composite filter assembly 2. The servo motor 4 drives the dynamic distribution ring 3 to rotate synchronously, causing the upper distribution plate 31, the middle baffle plate 32, and the bottom distribution plate 33, which are evenly distributed around it, to work together. The water first enters the area of ​​the upper distribution plate 31, where the upper distribution plate 31 initially disperses the water flow along the inclined direction. The overflow opening on the upper distribution plate 31, in conjunction with the internally staggered guide... The flow baffle 3101 further refines and divides the water flow, making the water flow transition more evenly to the middle layer baffle 32. The middle layer baffle 32 is connected to the threaded post 34 on the inner wall of the dynamic distribution ring 3 through the threaded rotating hole at its inner end, and the angle can be adjusted according to actual needs to adapt to the water flow under different flow conditions, so as to achieve more precise turbulence control. After being guided by multiple stages, the water flow continues to flow downward to the bottom flow divider plate 33 area. The outer end of the bottom flow divider plate 33 is inclined downward, and the water flow is finally rectified here and evenly introduced into the composite filter component 2 below, thus completing a series of tasks.

[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
