TECHNICAL FIELD

[0001] The present application relates to the technical field of pure water preparation, in particular to a pure water preparation device with multi-stage separation function. BACKGROUND

[0002] Currently, in the process of pure water preparation, in order to remove suspended solids in water, it is usually necessary to add flocculants and other chemicals to make the small particles in water aggregate into larger clumps for filtration or sedimentation. The flocculant stirring barrel, as a key equipment for realizing the integration of dosing, mixing and pollution discharge, plays an important role in this process. However, when the flocculant stirring barrel discharges the agglomerates deposited at the bottom, the inner wall of the barrel often has residual impurities attached to it. Since the barrel body is usually an integrally formed plastic barrel with high airtightness, it is very difficult to clean the residual impurities on the inner wall, and the operation is not convenient. Therefore, the related technical field proposes a pure water preparation and chemical water mixing integrated equipment to solve this problem. The Chinese patent with publication number "CN222331654U" discloses a pure water preparation and chemical water mixing integrated equipment. The equipment includes a barrel body, a feed pipe connected to the upper end near the front edge of the barrel body, a discharge assembly provided at the bottom end, a vertical rod rotatably provided at the middle of the upper end through a driving mechanism, a water distribution assembly provided on the inner wall near the upper edge, a plurality of stirring blades fixedly connected to the outer wall of the vertical rod from top to bottom, a sliding sleeve slidably sleeved on the outer wall of the vertical rod near the top end of the barrel body, and a guide assembly and a lifting mechanism. Through the cooperation of the driving mechanism, the vertical rod, the water distribution assembly, the stirring blades, the sliding sleeve, the connecting rod, the scraper rod one, the scraper rod two, the lifting mechanism and the guide assembly, the equipment not only can realize the mixing of chemical water, but also can conveniently clean the residual impurities attached to the inner wall during the preparation of pure water, which brings certain convenience to the workers. But the above device in the process of specific application still has obvious defects and deficiencies, although it has certain stirring mixing effect, and can scratch the inside of the tank to clean impurities, however, the overall structure design of the equipment has obvious disadvantages, which leads to its inability to be quickly removed from the inside of the tank, the vertical rod, the stirring blade, the sliding sleeve, the scraping rod and other structures are connected to form a complex whole, and are closely related to the driving mechanism, the lifting mechanism and other structures, the connection mode between the components lacks convenient disassembly design, so that the staff must spend a lot of time and energy to disassemble when they need to clean the internal structure thoroughly, which seriously affects the cleaning efficiency. In the cleaning process, when impurities adhere to the inside of the stirring structure, only relying on the simple cleaning method of flushing water, it is difficult to quickly and comprehensively remove the impurities on the stirring structure frame. The shape of the stirring blade is complex, there are many dead angles and gaps, once the agglomerates formed by the flocculating agent and impurities adhere to these parts, the water flow is difficult to fully flush, especially some impurities that have dried and hardened, which are difficult to be washed away by water. In addition, the scraper rod one and the scraper rod two will also be contaminated with a large amount of impurities during the scratching process, and the connection parts of the vertical rod, the sliding sleeve and other structures are also easy to accumulate dirt, which can only be cleaned by flushing water. This makes it easy for impurities to adhere to the stirring frame. These residual impurities not only affect the subsequent stirring effect, leading to uneven mixing of the medicine water, affecting the efficiency and quality of the flocculation reaction, but also become a breeding ground for bacteria, polluting the water quality of the pure water preparation, and affecting the subsequent sewage treatment effect. It can be seen that it has great limitations in practical application and needs to be improved. SUMMARY

[0017] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.

[0018] This application discloses a pure water preparation device with multi-stage separation function. For example... Figures 1-8 As shown, the system includes a main frame 1, in which ultrapure water filter elements 2 are fixedly installed in a linear arrangement at equal intervals. Each ultrapure water filter element 2 is connected in series with the others. A water-liquid mixing and treatment device 6 is fixedly installed on one side of the base frame 61. A power distribution box 4 is fixedly installed on the side of the main frame 1 away from the water-liquid mixing and treatment device 6. A controller is installed inside the power distribution box 4. The mixing treatment device 6 includes a base frame 61, which is fixedly installed on the side of the main frame 1 away from the distribution box 4. A tank 62 is fixedly installed on the top of the base frame 61. A wastewater addition pipe 7 is fixedly connected to the upper end of one side of the tank 62. A tank opening 63 is opened on the top of the tank 62. An adjustment mechanism 64 is fixedly installed on the rear side of the top of the base frame 61. A stirring mechanism 65 is fixedly installed at the front end of the adjustment mechanism 64. The main body of the stirring mechanism 65 passes through the tank opening 63 and is inserted into the inside of the tank 62. A filter mechanism 66 is fixedly installed at the bottom of the tank 62. The top of the filter mechanism 66 is connected to the output end at the bottom of the tank 62. During the application of this device, the device is based on the main frame 1. The ultrapure water filter elements 2 arranged linearly at equal intervals inside the device are connected in series as the core filtration unit for pure water preparation. The water-liquid mixing treatment device 6 on one side of the main frame 1 is responsible for pre-treating the wastewater. The distribution box 4 on one side is equipped with a controller to coordinate the operation of various components of the equipment. The operator sets parameters and monitors the status through the distribution box 4. The base frame 61 of the mixing and processing equipment 6 is fixed to one side of the main frame 1. The tank 62 on top of it is the reaction vessel. Wastewater enters through the wastewater addition pipe 7 at the upper end of one side of the tank 62. Flocculants and other materials can be added through the top tank opening 63. The adjustment mechanism 64 on the rear side of the top of the base frame 61 controls the raising and lowering of the stirring mechanism 65, so that the main body of the stirring mechanism 65 passes through the tank opening 63 and is inserted into the tank 62 to stir and mix the materials. The mixed materials are output through the bottom of the tank 62 to the filtration mechanism 66 for preliminary filtration, and then enter the ultrapure water filter element 2 in the main frame 1. After multi-stage filtration, pure water is obtained, completing the entire pure water preparation process. The setting of the stirring mechanism 65 in conjunction with the adjustment mechanism 64 makes the whole device easy to use and quick to inspect and maintain.

[0019] Each ultrapure water filter cartridge uses different materials. First, there's the PP cotton filter cartridge, the first stage of filtration. Made of melt-blown polypropylene with a pore size of 5-10 microns, it effectively removes large particles such as sediment, rust, and colloids, protecting subsequent precision filters and extending their lifespan. Next, there are activated carbon filters, including granular and compressed activated carbon cartridges. Granular activated carbon filters utilize the adsorption properties of activated carbon to remove residual chlorine, discoloration, odor, and some organic matter from the water. Compressed activated carbon filters further adsorb organic matter and pesticide residues, while also filtering some fine particles to improve the taste of the water. Finally, there's the ultrafiltration membrane cartridge, with a pore size of 0.01-0.1 microns, which can trap bacteria, viruses, colloids, and large organic molecules in the water. The filtration process requires no additives. Adding chemical agents can retain some beneficial minerals in the water and is often used for pretreatment or terminal purification. Then there is the RO reverse osmosis membrane filter, with extremely small pores, approximately 0.0001 microns. Under pressure, it can effectively remove almost all impurities in the water, such as dissolved salts, heavy metals, microorganisms, and organic matter, producing highly pure water. It is the core filter for producing high-purity water. In addition, there is a post-activated carbon filter, installed after the RO reverse osmosis membrane, used to adsorb any small amounts of odor that may be generated during the reverse osmosis process, further improving the taste of the water and ensuring the drinking safety of the output water. During the application of this equipment, the top of its tank 62 is fixedly connected to a ring pipe, and the bottom of the ring pipe has cleaning fluid spray nozzles at equal intervals. The rear side of the ring pipe is connected to an external water supply pipe via a hose.

[0020] Please refer to Figures 1-6The adjusting mechanism 64 includes a vertical rail 641, which is fixedly installed on the top rear side of the base frame 61. A first motor 642 is fixedly installed at the bottom of the vertical rail 641. The output end of the first motor 642 passes through the vertical rail 641 and is fixedly installed with a first lead screw 643. A sliding block 644 is threadedly connected to the outer surface of the first lead screw 643. A bracket 645 is fixedly installed on the top of the sliding block 644. A top plate 646 is fixedly installed on the top of the bracket 645. The end of the top plate 646 near the tank 62 is connected to the stirring mechanism 65. The front of the distribution box 4 is... The device is equipped with a display screen 3 at one end, and a control keyboard 5 is fixedly installed at the lower front end of the distribution box 4. The sliding block 644 has a convex shape when viewed from above, and the overall cross-sectional shape of the internal cavity of the vertical rail 641 is also convex. The side shape formed by the top plate 646 and the bracket 645 is L-shaped. During the application of this device, the vertical rail 641 of its adjustment mechanism 64 is fixedly installed on the top rear side of the base frame 61. After the first motor 642 at the bottom of the vertical rail 641 is started, its output end will pass through the vertical rail 641 and drive the first lead screw 643 to rotate. The outer surface of 643 is threadedly connected to the sliding block 644, and the sliding block 644 has a convex shape when viewed from above. The overall cross-sectional shape of the internal cavity of the vertical rail 641 is also convex. The two are compatible with each other, allowing the sliding block 644 to move stably up and down along the vertical rail 641. A bracket 645 is fixedly installed on the top of the sliding block 644, and a top plate 646 is fixedly installed on the top of the bracket 645. The side shape formed by the top plate 646 and the bracket 645 is L-shaped. The end of the top plate 646 near the tank 62 is connected to the stirring mechanism 65. Therefore, when the sliding block 644 moves up and down, the sliding block 644 can move up and down stably. When the moving block 644 moves up and down, it drives the stirring mechanism 65 to move synchronously through the bracket 645 and the top plate 646, realizing the movement of the stirring mechanism 65 in and out of the tank 62. At the same time, the operator can input control commands through the control keyboard 5 fixedly installed at the lower front of the distribution box 4. After these commands are processed by the controller inside the distribution box 4, they will drive the adjustment mechanism 64 to perform corresponding actions. The operating status of the equipment will be displayed in real time on the display screen 3 at the upper front of the distribution box 4, so that the operator can keep track of the working status of the adjustment mechanism 64 at any time.

[0021] Please refer to Figures 5-8The bottom of the rail frame 6761 has hinge slots 68 arranged in a ring at equal intervals. Each hinge slot 68 has a bottom scraper 69 hinged inside. The bottom of the bottom scraper 69 is fitted to the bottom of the tank body 62. A return spring 610 is fixedly connected to the top of the bottom scraper 69. The upper end of the return spring 610 is fixedly connected to the lower end of the outer surface of the rail frame 6761. The filtration mechanism 66 includes a drain valve 661, which is fixedly installed at the bottom output end of the tank body 62. A filter box 662 is fixedly installed at the bottom of the drain valve 661. A filter screen box 663 is slidably connected inside the filter box 662. The outer side of the filter screen box 663 is fixed... A sealing plate 664 is installed, and side fixing plates 665 are fixedly installed at both ends of the sealing plate 664. The end of the side fixing plate 665 is threadedly connected to the end of the side fixing plate 665. The end of the mounting screw 666 passes through the side fixing plate 665 and is threadedly connected to the outside of the filter box 662. A bridge-type handrail 667 is fixedly installed on the middle of the outside of the sealing plate 664. The sealing plate 664 covers the outlet of the filter box 662. A drain hopper 668 is fixedly installed at the bottom of the filter box 662. A drain pipe 669 is fixedly installed at the output end of the drain hopper 668. The output end of the drain pipe 669 is connected to the input end of the first ultrapure water filter element 2 inside the main frame 1. During the application of this device, a bottom scraper 69 is hinged within the equally spaced, annularly arranged hinge slots 68 at the bottom of the rail frame 6761. The bottom of the bottom scraper 69 is in contact with the bottom of the tank body 62. The upper end of the return spring 610 fixed at its top is connected to the lower end of the outer surface of the rail frame 6761. The elastic force of the return spring 610 keeps the bottom scraper 69 in close contact with the bottom of the tank. When the rail frame 6761 rotates, the bottom scraper 69 moves synchronously with it, scraping and removing impurities from the bottom of the tank to prevent sedimentation. In the filtration mechanism 66, the drain valve 661 at the bottom output end of the tank body 62 controls the material discharge. A filter screen is slidably connected inside the filter box 662 at the bottom of the drain valve 661. The filter box 663 can perform preliminary filtration of the discharged material, intercepting large particulate impurities. The sealing plate 664 on the outside of the filter box 663 covers the outlet of the filter box 662. The side fixing plates 665 at both ends of the sealing plate 664 are fixed to the filter box 662 by the mounting screws 666. By unscrewing the mounting screws 666, the filter box 663 can be pulled out for cleaning or replacement through the bridge-type handle 667 on the outside of the sealing plate 664. The drain hopper 668 at the bottom of the filter box 662 transports the filtered water through the drain pipe 669 to the first ultrapure water filter element 2 inside the main frame 1, providing pretreatment for subsequent deep filtration and ensuring the efficient operation of subsequent filter elements.

[0022] Please refer to Figures 7-10The adjusting assembly 676 includes a rail frame 6761, which is fixedly installed at the bottom of the connecting column 675. A second lead screw 6762 is rotatably connected inside the rail frame 6761. The top of the second lead screw 6762 is connected to the bottom output end of the third motor 674. The two ends of the second lead screw 6762 have opposite thread directions. Both ends of the second lead screw 6762 are threadedly connected to sliders 6763. The sliders 6763 are slidably connected to the two ends inside the rail frame 6761. Telescopic stirring groups 677 are installed in a ring at equal intervals on the outside of the sliders 6763. The telescopic stirring groups 677 include a hinge seat 6771 and a side plate 6772. The hinge seat 6771 is fixedly installed in a ring at equal intervals on the slider. On the outer side of block 6763, a connecting rod 6773 is hinged to the outer side of hinge seat 6771. A hinge frame 6774 is fixedly installed on the outer end of the connecting rod 6773. The upper and lower ends of the inner side of side plate 6772 are hinged to the outer end of hinge frame 6774. Stirring plates 6775 are fixedly connected to the outer side of side plate 6772 at equal intervals. A side scraper 6776 is fixedly installed on the outer side of stirring plate 6775. The outer side of side scraper 6776 is in close contact with the inner wall of tank 62. During use, when the third motor 674 runs, it will drive the second lead screw 6762 to rotate synchronously. Since the threads at both ends of the second lead screw 6762 turn in opposite directions and both ends are threadedly connected to sliders 6763, the sliders 6763 are slidably connected. Inside the rail frame 6761 at both ends, when the second lead screw 6762 rotates, the sliders 6763 at both ends will slide in opposite directions within the rail frame 6761. The telescopic stirring assembly 677 is installed on the outside of the slider 6763 in a ring at equal intervals. The hinge seats 6771 contained therein are fixed on the outside of the slider 6763 in a ring at equal intervals. The outer end of the connecting rod 6773 hinged to the outside of the hinge seat 6771 is fixed with a hinge frame 6774. The upper and lower ends of the inner side of the side plate 6772 are hinged to the outer end of the hinge frame 6774. When the slider 6763 slides, it will drive the side plate 6772 to expand or contract through the hinge seat 6771, the connecting rod 6773 and the hinge frame 6774. The fixed-spaced stirring plates 6775 move with the side plates 6772, stirring the materials inside the tank 62. The side scrapers 6776 fixed to the outside of the stirring plates 6775 are in contact with the inner wall of the tank 62, scraping the tank wall during stirring to prevent impurities from adhering. In this structure, the rotation direction design of the second lead screw 6762 realizes the reverse linkage of the slider 6763, providing power for the expansion and contraction of the telescopic stirring assembly 677. The multi-part hinged cooperation of the telescopic stirring assembly 677 ensures flexible adjustment of the stirring range. The stirring plates 6775 directly act on the materials to improve the mixing effect, while the side scrapers 6776 clean the tank wall, together ensuring the high efficiency and cleanliness of the material processing inside the tank 62.

During the operation of this device, the circular plate 651 of its stirring mechanism 65 is fixed to the front end of the top plate 646. After the second motor 652 at the top of the circular plate 651 is started, its output end passes through the circular plate 651 and drives the connecting shaft 653 to rotate. The stirring module 67 fixed at the bottom of the connecting shaft 653 then rotates. The sealing cover 67... 1. A rotating disc 672, located in the middle of the inner side of a sealing cover 671, covers the top of the tank opening 63 and is connected to the top of a connecting frame 673. The top of the connecting frame 673 is fixed to the bottom of a connecting shaft 653. A third motor 674 inside the connecting frame 673 starts, its output end passing through the rotating disc 672 to drive the connecting column 675 to rotate. The adjusting component 676 at the bottom of the connecting column 675 then rotates, causing the telescopic stirring assembly 677 outside the adjusting component 676 to perform corresponding actions, thereby achieving the stirring of the material inside the tank 62. The second motor 652 and the third motor 674 have clearly defined roles. The second motor 652 drives... The moving stirring module 67 rotates as a whole, and the third motor 674 drives the telescopic stirring group 677 to move through the adjusting component 676. The dual power cooperation makes the stirring range more flexible and can fully cover the internal space of the tank 62, improving the uniformity of material mixing. The sealing cover 671 tightly covers the tank opening 63 to prevent material splashing during stirring and ensure the sealing of the tank 62. The rotating connection design between the connecting frame 673 and the turntable 672 reduces the frictional resistance of the components during operation, improves the stability of the mechanism, and extends the service life of the equipment. At the same time, the modular component structure facilitates individual inspection or replacement, reducing maintenance costs.

[0024] The implementation principle of a pure water preparation device with multi-stage separation function in this application embodiment is as follows: During the application of this device, the operator first needs to input relevant operating parameters through the control keyboard 5 at the lower front of the distribution box 4. These parameters are transmitted to the controller inside the distribution box 4. After being processed by the controller, they are displayed on the display screen 3 at the upper front of the distribution box 4 so that the operator can check the operating status of the equipment in real time. At the same time, the controller coordinates and controls the operation of various components such as the main frame 1 and the mixing and processing equipment 6. The distribution box 4 provides power support for the operation of the entire device to ensure that each component can work normally. After the equipment is started and the parameter settings are completed, the mixing and processing equipment 6 enters the preparation stage, and the upper side of the tank 62 is fixed. A wastewater addition pipe 7 is connected, through which wastewater is added into the tank 62. Simultaneously, operators can add flocculants and other materials into the tank 62 through the tank opening 63. Additionally, a ring pipe is fixedly connected to the top of the tank 62, and its rear end is connected to an external water supply pipe via a flexible hose. This design allows the ring pipe to provide cleaning fluid when needed, preparing for subsequent cleaning work. After the materials are added, the adjusting mechanism 64 is activated, and the first motor 642 at the bottom of the vertical rail 641 begins to run. Its output end drives the first lead screw 643, which passes through the vertical rail 641, to rotate inside the vertical rail 641. Since the sliding block 644 and the first lead screw 643 are threadedly connected, and the sliding block 644 has a convex shape when viewed from above, the sliding block 644... The internal cavity of the vertical rail 641 also has a convex cross-sectional shape. These two elements work together to allow the sliding block 644 to move smoothly up and down along the vertical rail 641. A bracket 645 is fixedly installed on the top of the sliding block 644, and a top plate 646 is fixedly installed on the top of the bracket 645. Therefore, when the sliding block 644 moves, it will drive the top plate 646 to move along with it through the bracket 645. The end of the top plate 646 closest to the tank 62 is connected to the stirring mechanism 65, so the stirring mechanism 65 will also move, causing it to descend and allowing the stirring module 67 to penetrate deeper into the tank 62 until the sealing cap 671 covers the top of the tank opening 63, ensuring the sealing of the tank 62. Then, the stirring mechanism 65 begins to work, and the top of the circular plate 651... The second motor 652 starts, and its output end passes through the circular plate 651 and drives the connecting shaft 653 to rotate. The bottom of the connecting shaft 653 is fixedly installed with the stirring module 67, so the connecting shaft 653 will drive the entire stirring module 67 to rotate together. At the same time, the third motor 674 inside the connecting frame 673 will also run, and its output end passes through the turntable 672 and drives the connecting column 675 to rotate. The bottom of the connecting column 675 is fixedly installed with the rail frame 6761 in the adjusting assembly 676, which in turn drives the second lead screw 6762 inside the rail frame 6761 to rotate. Since the threads at both ends of the second lead screw 6762 turn in opposite directions, when the second lead screw 6762 rotates, the sliders 6763 connected by the threads at both ends will slide in opposite directions inside the rail frame 6761.Hinges 6771 are fixedly installed in a ring at equal intervals on the outer side of slider 6763. Connecting rods 6773 are hinged to the outer side of hinges 6771. A hinge frame 6774 is fixedly installed at the outer end of the connecting rod 6773. The upper and lower ends of the inner side of side plate 6772 are hinged to the outer ends of the hinge frame 6774. Therefore, when slider 6763 slides, it drives the connecting rod 6773 to move through hinges 6771. The connecting rod 6773 then drives the side plate 6772 to expand or contract through the hinge frame 6774 until the side scraper 6776 on the outer side of side plate 6772 is tightly fitted against the inner wall of tank 62. During the rotation of the entire mixing module 67 driven by the coupling 653, when the telescopic mixing group 677 is in a self-rotating state, the third motor 674 inside the connecting frame 673 continuously drives the second lead screw 6762 inside the rail frame 6761 to rotate in both directions, causing the sliders 6763 to slide towards and away from each other continuously. This allows the telescopic mixing group 677 to reciprocate and extend. In this way, the mixing plates 6775, which are fixedly connected at equal intervals on the outer side of the side plate 6772, can not only rotate with the mixing module 67, but also change the mixing range with the reciprocating extension and retraction of the telescopic mixing group 677, thus more thoroughly mixing the materials inside the tank 62. The stirring ensures the materials are mixed evenly. When cleaning is required, the adjustable side scraper 6776 can be adjusted to fit against the inner wall of the tank 62. At this time, the side scraper 6776 will scrape the inner wall of the tank 62 from multiple directions as the stirring module 67 rotates and the telescopic stirring assembly 677 extends and retracts, preventing impurities from adhering to the inner wall of the tank 62. Furthermore, the bottom of the rail frame 6761 has equally spaced, ring-shaped hinge slots 68. Each hinge slot 68 has a bottom scraper 69 hinged inside. A return spring 610 is fixedly connected to the top of the bottom scraper 69, and the upper end of the return spring 610 is fixedly connected to the lower end of the outer surface of the rail frame 6761. Under the elastic force of the return spring 610, the bottom of the bottom scraper 69 remains in contact with the bottom of the tank 62. As the stirring module 67 rotates and the telescopic stirring assembly 677 moves, it thoroughly scrapes the bottom of the tank 62, thus cleaning impurities. If cleaning of the inside of the tank 62 is required during stirring, a water pump can be connected via a hose. The water pump supplies cleaning fluid, which is sprayed out through an annular pipe and cleaning fluid nozzles spaced evenly at the bottom. The cleaning fluid, combined with the scraping action of the side scrapers 6776 and the bottom scraper 69, further enhances the cleaning effect. After the materials have completed the mixing reaction inside the tank 62, the drain valve 661 at the bottom of the tank 62 will open. The mixed materials will enter the filter box 662 in the filter mechanism 66 through the drain valve 661. A filter screen box 663 is slidably connected inside the filter box 662. The filter screen box 663 will filter the materials, trapping agglomerates and other impurities. The filtered water will enter the drain hopper 668 at the bottom of the filter box 662, and then be transported to the main filter through the drain pipe 669 fixedly installed at the output end of the drain hopper 668. The water first enters the first ultrapure water filter element 2 inside the main frame 1, which is a PP cotton filter element. The PP cotton filter element is made of melt-blown polypropylene with a pore size of 5-10 microns. It effectively removes large particulate impurities such as sediment, rust, and colloids from the water, while also protecting subsequent precision filter elements and extending their service life. Water filtered through the PP cotton filter element then enters the next ultrapure water filter element 2, which is a granular activated carbon filter element. The granular activated carbon filter element utilizes the adsorption properties of activated carbon to remove residual chlorine, discoloration, and other impurities from the water. After removing some organic matter, the water then enters a compressed activated carbon filter, which further adsorbs organic matter, pesticide residues, and other pollutants, while also filtering out some fine particles to improve the taste. Next, the water passes through an ultrafiltration membrane filter. Ultrafiltration membranes have pore sizes of 0.01-0.1 microns, which can trap bacteria, viruses, colloids, and large organic molecules in the water. This filtration process requires no chemical additives and retains some beneficial minerals, often used for pretreatment or final-point purification. The ultrafiltration water then enters an RO reverse osmosis membrane filter. The core of the RO reverse osmosis membrane filter is its extremely small pore size, approximately 0.0001 microns. Under pressure, it can effectively remove almost all impurities in the water, such as dissolved salts, heavy metals, microorganisms, and organic matter, producing highly pure water. It is the core filter for producing high-purity water. Finally, the water passes through a post-activated carbon filter, which is installed after the RO reverse osmosis membrane. This filter is used to adsorb any small amount of odor that may be produced during the reverse osmosis process, further improving the taste of the water and ensuring the drinking safety of the output water. This completes the entire process of pure water preparation. When the equipment has been running for a period of time and the internal structure needs cleaning, first start the third motor 674 inside the connecting frame 673, which drives the second lead screw 6762 inside the rail frame 6761 of the adjusting component 676. Since the threads at both ends of the second lead screw 6762 turn in opposite directions, it drives the slider 6763 to slide towards each other inside the rail frame 6761, thereby causing the telescopic stirring assembly 677 to fully retract. After that, the adjusting mechanism 64 will play its role again, and the first motor 642 at the bottom of the vertical rail 641 will run, driving the first lead screw 643 to rotate, causing the sliding block 644 to rise along the vertical rail 641. Through the bracket 645 and the top plate 646, the stirring mechanism 65 will rise, thereby pulling the stirring module 67, which was originally deep inside the tank 62, out of the tank opening 63 and detaching it from the tank 62. At this time, the operator can quickly adjust the stirring plate 6775, the side scraper 6776, and the bottom scraper 69. The components are thoroughly cleaned to avoid impurities. For the filter screen box 663 in the filtration mechanism 66, since a sealing plate 664 is fixedly installed on its outside, and the side fixing plates 665 at both ends of the sealing plate 664 are installed by the mounting screws 666, when it is necessary to clean or replace the filter screen box 663, the operator only needs to unscrew the mounting screws 666, and then pull out the sealing plate 664 and the filter screen box 663 together from the outlet of the filter box 662 through the bridge-type handle 667 fixedly installed in the middle of the outer side of the sealing plate 664 for cleaning or replacement. In addition, the ultrapure water filter element 2 inside the main frame 1 can also be replaced periodically as needed according to its usage to ensure that the filtration effect of the entire filtration system is always good. The removal of the ultrapure water filter element 2 is a current technical means, which can be achieved by spring clips or threaded connections, etc., which will not be described in detail here. In this technical solution, the stirring mechanism 65 first penetrates the tank 62 to operate. During cleaning, the third motor 674 drives the second lead screw 6762 inside the rail frame 6761 to fully retract the telescopic stirring assembly 677. Then, the adjusting mechanism 64 drives the first lead screw 643 to rotate, causing the stirring mechanism 65 to rise and the stirring module 67 to be pulled out from the tank opening 63. This eliminates the need for complex disassembly, solving the problem of difficult disassembly of the stirring structure. At the same time, the side scraper 6776 and bottom scraper 69 in the stirring mechanism 65 can scrape the inner wall and bottom of the tank 62, reducing the adhesion of impurities. The annular pipe and cleaning fluid spray pipe at the top of the tank 62 can spray cleaning fluid to assist in cleaning. Furthermore, the stirring module 67 can be thoroughly cleaned after being pulled out, avoiding the problem of not being able to clean dead corners by rinsing alone. In this technical solution, the ultrapure water filter cartridge 2 uses different materials for multi-stage filtration. The PP cotton filter cartridge first removes large particulate impurities, protecting subsequent filter cartridges; the activated carbon filter cartridge effectively adsorbs various impurities in the water, improving water quality; the ultrafiltration membrane and RO reverse osmosis membrane filter cartridges can remove bacteria, viruses, dissolved salts, and other impurities; the post-activated carbon filter cartridge further improves the taste. Through this multi-stage filtration, the purity of pure water can be significantly improved, effectively solving the problem of impurities affecting subsequent treatment in the background technology. The adjustment component 676 in this technical solution, through the cooperation of the second lead screw 6762 and the slider 6763, can adjust the degree of expansion of the side plate 6772, so that the side scraper 6776 fits against the inner wall of the tank 62. At the same time, the extension... The retractable agitator 677 can reciprocate during rotation. The agitator plate 6775 increases the contact area with the material and can change the agitation range, making the chemical mixture more uniform and improving the efficiency of the flocculation reaction. Moreover, the agitator structure is easy to clean, reducing impurity residue and avoiding the situation where impurities affect the agitation effect. The wastewater addition pipe 7 is fixedly connected to the upper side of the tank 62 for adding wastewater into the tank 62, changing the traditional method of adding wastewater from the tank opening 63, making it more convenient to add wastewater. The annular pipe and cleaning fluid spray pipe are mainly used to spray cleaning fluid during the agitation process or a special cleaning stage. The cleaning fluid can wash the inner wall of the tank 62 and the agitator components, in conjunction with the side scraper 6776. The scraping action of the bottom scraper 69 further enhances the cleaning effect, ensuring the cleanliness of the inside of the tank 62. The annular tube and cleaning fluid spray pipe are existing technologies, so they will not be described in detail here. The interconnected ultrapure water filter elements 2 ensure that water passes through each level of filter element in sequence. Each level of filter element can treat different impurities, thereby fully removing various impurities from the water and ensuring the quality of the final output water. The convex structure design of the slider 6763 makes the sliding block 644 move more smoothly in the vertical rail 641 without deviation, providing stable guidance for the lifting and lowering of the stirring mechanism 65 and ensuring the stability of the equipment operation. The sealing plate 664 covers the outlet of the filter box 662, which can ensure the filter box The sealing of 662 prevents water leakage; the cooperation between the side fixing plate 665 and the mounting screw 666 facilitates the removal of the sealing plate 664 and the filter screen box 663 from the filter box 662, making it convenient to disassemble and maintain the filter screen box 663. The function of the return spring 610 is to apply a downward elastic force to the bottom scraper 69, so that the bottom scraper 69 can always be in close contact with the bottom of the tank 62, thereby ensuring that the bottom scraper 69 can effectively scrape the bottom of the tank during rotation and when the telescopic stirring group 677 is in action, cleaning the impurities at the bottom of the tank and preventing impurities from accumulating at the bottom of the tank. At the same time, during the disassembly and assembly of the stirring mechanism 65, the telescopic spring can adapt to the extension and retraction, which can prevent the bottom scraper 69 from hindering its removal for maintenance.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
