Description

Technical Field

[0001] This utility model relates to the field of purified water treatment technology, and in particular to a purified water treatment device for medical use. Background Technology

[0002] Purified water treatment in the medical field is an indispensable and crucial step in pharmaceutical manufacturing, hospital preparation, medical device cleaning, and hemodialysis. Its core objective is to remove impurities, ions, microorganisms, and other harmful substances from raw water through a series of physical and chemical treatment methods to obtain high-purity water that meets GMP standards. This water quality directly affects the safety and effectiveness of drug preparation, device sterilization, and clinical use, playing a vital role in safeguarding patient health. Medical purified water treatment equipment occupies an important position in medical water systems. As a key component in the water purification process, its filtration performance and treatment technology have a decisive impact on effluent quality, operational efficiency, and system stability. Especially in the core step of purified water pretreatment, existing purified water treatment equipment has gradually revealed a series of significant limitations and technical problems when dealing with complex water sources, multi-component impurities, and microbial contamination.

[0003] Utility model patent CN208532415U discloses a purified water treatment device, including a source water end, a primary filter component connected downstream of the source water end via a pipeline, a first-stage water treatment component connected downstream of the primary filter component via a pipeline, and a second-stage water treatment component connected downstream of the first-stage water treatment component. The outlet end of the second-stage water treatment component is connected to a purified water tank, and the outlet end of the purified water tank is connected to an external supply workshop via a pipeline. A first-stage high-pressure pump is installed on the pipeline between the source water end and the primary filter component, and a second-stage high-pressure pump is installed on the pipeline between the first-stage and second-stage water treatment components. This device purifies tap water through a multi-step process, effectively reducing the content of various impurities and particulate matter in the water, and more effectively meeting the needs of pharmaceutical preparation.

[0004] However, existing technologies for medical purified water treatment, especially in the pretreatment stage, suffer from insufficient filtration efficiency. Specifically, the primary filtration components exhibit low removal rates of suspended solids, colloids, and large organic molecules, leading to easy fouling and even clogging of the subsequent reverse osmosis membrane. This, in turn, affects the overall system's operational efficiency and the stability of the effluent quality. Furthermore, some equipment lacks adaptive adjustment capabilities to varying water quality, is complex to operate, and requires frequent maintenance, failing to meet the practical needs of modern medical institutions for continuous and stable water supply, intelligent control, and low operating costs. Therefore, addressing these shortcomings of existing technologies, we urgently need an innovative purified water treatment device for medical applications to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a purified water treatment device for medical use, which solves the problem that the primary filtration component in the prior art has a low removal rate of suspended solids, colloids and macromolecular organic matter, which leads to the subsequent reverse osmosis membrane being easily contaminated or even blocked, thus affecting the overall system operating efficiency and the stability of the effluent water quality.

[0006] To achieve the above objectives, this utility model provides a purified water treatment device for medical use, including a box body, and a plurality of adsorption frames fixedly connected to the upper inner side of the box body, and a top frame fixedly connected to the top of the box body.

[0007] A screw is rotatably connected to the inner side of the top frame, and one end of the screw is connected to a nut seat by a threaded connection. A drive motor is fixedly connected to one side of the outer wall of the top frame by bolts, and one end of the screw passes through the side wall of the top frame and is connected to the output shaft of the drive motor for transmission. A connecting plate is fixedly connected to the bottom of the nut seat. Several combing rods are provided on the inner side of all the adsorption frames, and the top of all the combing rods is fixedly connected to the bottom of the connecting plate. A filter plate is detachably connected to the lower inner side of the box, and several adsorption packing plates are fixedly connected to the bottom of the filter plate.

[0008] The outer side of the box is connected to a cover plate via a hinge, and a water valve is installed on the lower side of the box.

[0009] The filter plate has mounting plates fixedly connected to both sides of its top, and both mounting plates are fixedly connected to the inner wall of the housing by bolts.

[0010] The top of the nut seat is fixedly connected to a slider, and the slider is slidably connected to the top inner side of the top frame through a groove.

[0011] One end of the screw is rotatably connected to the inner wall of the top frame via a rotating shaft, and the other end of the screw passes through the side wall of the top frame via a bearing sleeve. Both sides of the top frame are fixedly connected to ultraviolet lamp panels.

[0012] The connecting plate has sliding blocks fixedly connected to both sides, and both sliding blocks are slidably connected to the inner wall of the box through sliding grooves.

[0013] This utility model discloses a purified water treatment device for medical use. It employs a mechanical stirring system within the adsorption frame, consisting of a screw driven by a motor, a nut seat, a connecting plate, and a combing rod. This system continuously agitates the water as it flows through the adsorption frame, effectively preventing localized blockages and short-circuiting, ensuring full contact between the water and the adsorption material, thus improving adsorption efficiency and pollutant removal rate, and enhancing pretreatment effects. An adsorption packing plate is added to the bottom of the filter plate, using a new material with a higher specific surface area and adsorption capacity. This efficiently intercepts residual impurities in the water, reducing the load on subsequent deep treatment units, extending the lifespan of the reverse osmosis membrane, and improving the overall system's operational stability and economy. The device utilizes a detachable filter plate and adsorption packing plate structure, facilitating the replacement of different types or combinations of adsorption materials according to different water source characteristics. This enhances the device's adaptability to complex water quality changes and also facilitates daily maintenance and replacement, reducing operating costs and downtime. Furthermore, the device features a compact overall structure, a high degree of automation, and simple operation, enabling continuous and stable water supply, meeting the practical needs of modern medical units for intelligent, energy-saving, and automated operation. Finally, by introducing a linkage control mechanism between the top frame, screw, and drive motor, active intervention in the water flow state is achieved, improving the controllability and response speed of equipment operation, and further ensuring the stability and safety of the effluent water quality. In summary, this purified water treatment equipment for medical use outperforms existing technologies in terms of filtration efficiency, treatment precision, system stability, ease of operation, and adaptability. It better meets the medical industry's demand for high-quality purified water, providing safe and reliable water quality assurance for key processes such as hospital preparations, drug formulation, instrument cleaning, and dialysis.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figure 1-5 ,

[0023] A purified water treatment device for medical use includes a housing 1, and a plurality of adsorption frames 13 are fixedly connected to the upper inner side of the housing 1, and a top frame 4 is fixedly connected to the top of the housing 1.

[0024] A screw 5 is rotatably connected to the inner side of the top frame 4, and one end of the screw 5 is connected to a nut seat 6 by a threaded connection. A drive motor 18 is fixedly connected to one side of the outer wall of the top frame 4 by bolts, and one end of the screw 5 passes through the side wall of the top frame 4 and is connected to the output shaft of the drive motor 18 for transmission. A connecting plate 10 is fixedly connected to the bottom of the nut seat 6. Several combing rods 14 are provided on the inner side of all the adsorption frames 13, and the top of all the combing rods 14 is fixedly connected to the bottom of the connecting plate 10. A filter plate 15 is detachably connected to the lower inner side of the box body 1, and several adsorption packing plates 17 are fixedly connected to the bottom of the filter plate 15.

[0025] When raw water needs purification, the water to be treated is first introduced into several adsorption frames 13 located at the top of the tank 1 through the inlet pipe. These adsorption frames 13 are filled with preliminary filtration media, such as activated carbon, quartz sand, or porous ceramics, to preliminarily adsorb and retain suspended particles, organic matter, and some heavy metal ions in the water. Simultaneously, the drive motor 18, fixedly connected to one side of the outer wall of the top frame 4, is activated. The output shaft of the drive motor 18 drives the screw 5, which is connected to it, to rotate. The screw 5 is threadedly connected to the nut seat 6, which slides along the inner side of the top frame 4. During the rotation of the screw 5, the nut seat 6 reciprocates linearly along its length, causing the connecting plate 10 fixedly connected below to move synchronously. Multiple combing rods 14 are fixedly connected to the bottom of the connecting plate 10. These combing rods 14 are vertically inserted into the adsorption frames 13 and move synchronously with the water. The water flows up and down or horizontally within the adsorption frame 13 as the connecting plate 10 moves, dynamically agitating the water flow within the adsorption frame 13. This allows the water to fully diffuse and uniformly contact the filter medium within the adsorption packing, thereby improving adsorption efficiency and removal rate. After initial filtration, the water continues to flow downwards into the area of ​​the detachable filter plate 15 located at the lower inner side of the housing 1. Several adsorption packing plates 17 are fixedly connected to the bottom of the filter plate 15. The adsorption packing plates 17 are filled with high-density ion exchange resin, ultrafiltration membrane components, or other nanoscale adsorption materials for further deep purification of residual microparticles, dissolved salts, bacteria, and viruses in the water, achieving stable water quality compliance. Throughout the process, the adsorption frame 13, combing rod 14, filter plate 15, and adsorption packing plates 17 work together to form a multi-stage composite filtration structure, ensuring that the effluent water quality meets medical water standards.

[0026] Furthermore, a cover plate 2 is hinged to one side of the outer side of the housing 1, and a water valve 3 is installed on the lower side of the housing 1. After the equipment has finished operating, the adsorption frame 13, filter plate 15 and adsorption packing plate 17 inside the housing 1 can be inspected, cleaned or replaced by opening the cover plate 2. At the same time, when drainage or cleaning is required, the residual water in the housing 1 can be quickly discharged by opening the water valve 3. This structural design improves the maintainability and ease of operation of the equipment, and achieves the effect of facilitating daily maintenance and system cleaning.

[0027] Furthermore, mounting plates 16 are fixedly connected to both sides of the top of the filter plate 15, and both mounting plates 16 are fixedly connected to the inner wall of the housing 1 by bolts. When installing or replacing the filter plate 15, the quick installation and removal operation can be completed simply by unloading and tightening the bolts on the mounting plates 16, without the need to disassemble the entire equipment. This improves maintenance efficiency and structural stability, while ensuring the stability of the filter plate 15 under the impact of water flow, thereby enhancing the reliability of the filter assembly installation and facilitating replacement.

[0028] Furthermore, a slider 8 is fixedly connected to the top of the nut seat 6, and the slider 8 is slidably connected to the inner top of the top frame 4 through the slide groove 9. During the rotation of the screw 5 driven by the drive motor 18, the nut seat 6 moves along its length direction with the rotation of the screw 5. At this time, the slider 8 slides synchronously along the direction of the slide groove 9, which plays a guiding and stabilizing support role, effectively preventing the nut seat 6 from deviating or jamming during the movement, thereby ensuring the smoothness and accuracy of the operation of the connecting plate 10 and the combing rod 14, and achieving the effect of improving the stability of mechanical transmission and extending service life.

[0029] Furthermore, one end of the screw 5 is rotatably connected to the inner wall of the top frame 4 via a rotating shaft, and the other end of the screw 5 passes through the side wall of the top frame 4 via a bearing sleeve. Both sides of the top frame 4 are fixedly connected to ultraviolet lamp plates 7. During the rotation of the screw 5, its two ends are stably supported by the rotating shaft and the bearing sleeve respectively, ensuring the smooth operation of the transmission system. At the same time, the ultraviolet lamp plates 7 can sterilize and disinfect the internal space of the box 1 during equipment shutdown or maintenance, preventing the growth of microorganisms from affecting water quality safety, thus achieving the dual effect of improving equipment operation stability and ensuring water quality hygiene.

[0030] Furthermore, sliding blocks 11 are fixedly connected to both sides of the connecting plate 10, and both sliding blocks 11 are slidably connected to the inner wall of the box 1 through the sliding groove 12. During the process of the drive motor 18 driving the connecting plate 10 to move back and forth, the sliding blocks 11 slide synchronously along the direction of the sliding groove 12, providing lateral or vertical guiding support for the connecting plate 10, avoiding shaking or displacement caused by water flow resistance or mechanical vibration, thereby ensuring the accuracy and stability of the running trajectory of the combing rod 14 in the adsorption frame 13, and achieving the effect of enhancing the uniformity of stirring and improving the adsorption efficiency.

[0031] In summary:

[0032] When raw water needs purification, the water to be treated is first introduced into several adsorption frames 13 located in the upper part of the tank 1 through the inlet pipe. These adsorption frames 13 are filled with preliminary filter media, such as activated carbon, quartz sand, or porous ceramics, to preliminarily adsorb and retain suspended particles, organic matter, and some heavy metal ions in the water. At the same time, the drive motor 18, which is fixedly connected to one side of the outer wall of the top frame 4, is started. The output shaft of the drive motor 18 drives the screw 5, which is connected to it, to rotate. The screw 5 is connected to the nut seat 6, which slides on the inner side of the top frame 4, by a threaded connection. During the rotation of the screw 5, the nut seat 6 reciprocates linearly along its length, and drives the connecting plate 10 fixedly connected below to move synchronously. Multiple combing rods 14 are fixedly connected to the bottom of the plate 10. These combing rods 14 are vertically inserted into the adsorption frame 13 and slide up and down or horizontally within the adsorption frame 13 as the connecting plate 10 moves, dynamically agitating the water flow within the adsorption frame 13. This ensures that the water flow is fully diffused and evenly contacts the filter medium in the adsorption packing, thereby improving adsorption efficiency and removal rate. Simultaneously, to ensure the stability of the nut seat 6 during movement, a slider 8 fixedly connected to its top slides synchronously along the groove 9 on the inner top of the top frame 4, providing guidance and support to prevent offset or jamming. Furthermore, sliding blocks 11 are fixedly connected to both sides of the connecting plate 10. Both sliding blocks 11 are slidably connected to the inner wall of the housing 1 via sliding grooves 12, further enhancing the connection. The stability of plate 10 during operation ensures the accuracy and stability of the combing rod 14's trajectory within the adsorption frame 13. After initial filtration, the water continues to flow downwards, entering the detachable filter plate 15 area located at the lower inner side of the housing 1. This filter plate 15 is fixed to the inner wall of the housing 1 via mounting plates 16 on both sides of the top and bolts, facilitating quick installation, removal, and replacement, thus improving maintenance efficiency and structural stability. Several adsorption packing plates 17 are fixedly connected to the bottom of the filter plate 15. These plates are filled with high-density ion exchange resin, ultrafiltration membrane modules, or other nanoscale adsorption materials for further deep purification of residual microparticles, dissolved salts, bacteria, and viruses in the water, achieving stable water quality compliance. The entire process... During the process, the adsorption frame 13, combing rod 14, filter plate 15, and adsorption packing plate 17 work together to form a multi-stage composite filtration structure, ensuring that the effluent water quality meets medical water standards. After the equipment has finished operating, the internal components can be inspected, cleaned, or replaced by opening the hinged cover 2 on the outside of the housing 1. At the same time, when drainage or cleaning is required, the residual water in the housing 1 can be quickly discharged by opening the water valve 3 installed on the lower side of the housing 1, which improves the maintainability and ease of operation of the equipment. To further enhance the hygiene and safety of the equipment, ultraviolet lamp plates 7 are also fixedly connected to both sides of the top frame 4, which can be used to sterilize and disinfect the internal space of the housing 1 during equipment shutdown or maintenance to prevent the growth of microorganisms from affecting water quality safety.By incorporating a mechanical stirring system consisting of a screw 5 driven by a drive motor 18, a nut seat 6, a connecting plate 10, and a combing rod 14 within the adsorption frame 13, combined with a dual guiding structure of slider 8 and chute 9, and sliding block 11 and chute 12, continuous disturbance of the water flow is achieved. This effectively prevents local blockage and water flow short-circuiting, ensuring full contact between water and the adsorption material, thus improving adsorption efficiency and pollutant removal rate, and achieving the goal of enhancing pretreatment effect. Secondly, to address the issue of "subsequent reverse osmosis membranes being easily fouled or even clogged," this equipment optimizes the multi-stage filtration structure design, particularly by adding an adsorption packing plate 17 at the bottom of the filter plate 15. This plate utilizes a new material with a higher specific surface area and adsorption capacity to efficiently intercept residual impurities in the water, reducing the load on subsequent deep treatment units, extending the service life of the reverse osmosis membrane, and improving the overall system's operational stability and economy. Furthermore, addressing the issue of "lack of adaptive adjustment capability in the face of varying water quality fluctuations," this device employs a modular, detachable filter plate 15 and adsorption packing plate 17 structure. This facilitates the replacement of different types or combinations of adsorption materials according to different water source characteristics, enhancing the equipment's adaptability to complex water quality changes. It also facilitates daily maintenance and replacement, reducing operating costs and downtime. In addition, the structure of the cover plate 2 and water valve 3 provides excellent maintainability and cleaning capabilities, further ensuring the long-term water quality safety of the system. Simultaneously, the introduction of the ultraviolet lamp plate 7 allows for periodic sterilization of the interior of the housing 1 during non-operational periods, effectively inhibiting microbial growth, preventing secondary contamination risks, and improving the overall hygiene level of the equipment. Finally, the device features a compact overall structure, a high degree of automation, and simple operation, enabling continuous and stable water supply, meeting the actual needs of modern medical units for intelligent, energy-saving, and automated operation. In summary, this purified water treatment equipment for medical use is superior to existing technologies in terms of filtration efficiency, treatment accuracy, system stability, ease of operation, and adaptability. It can better meet the medical industry's demand for high-quality purified water and provide safe and reliable water quality assurance for key processes such as hospital preparation, drug formulation, instrument cleaning, and dialysis.
