Traditional water purification technologies such as single-stage reverse osmosis and ion exchange have problems such as incomplete removal of impurities and easy secondary pollution, making it difficult to meet the demand for high-purity water. With the increasing standardization requirements of the industry, dual-stage reverse osmosis devices, with their advantages of deep filtration through two-stage membranes, can efficiently remove harmful substances from water, meet the water standards of key processes, and have become an important piece of equipment to solve traditional pain points and ensure the quality of herbal medicine slices.

It includes a disinfection box and a filter box. The filter box is fixed to the top of the disinfection box by a support rod. A feeding pipe is installed on the top of the filter box, and a discharge pipe connects the filter box and the disinfection box. A filter layer is installed inside the filter box. An opening is provided on one side wall of the filter box, and a baffle is installed inside the opening. A handle is installed on one side wall of the baffle, and a connecting rod is welded to the other end of the baffle. A brush is fixed to one end of the connecting rod. Through holes are opened on both side walls of the disinfection box, and a rotating cylinder with the same water tank is rotatably installed in both through holes.

This patent has a novel design, which can extend the contact time between the solution and the ultraviolet disinfection lamp, improve the sterilization effect, has good filtration effect, and is easy to operate, making it worthy of promotion.

[0004] However, when the above-mentioned device is used, it is difficult to match the high water volume demand during the sterilization of water with ultraviolet lamps. This can easily lead to the ultraviolet lamps sterilizing the water for too long or too short a time, which in turn affects the efficiency and consistency of subsequent water treatment. Therefore, a two-stage reverse osmosis device for the production of traditional Chinese medicine decoction pieces is proposed to solve the above-mentioned problems. Summary of the Invention

The scraper ring contacts the adsorption sleeve and is used to push the particles at the filter screen of the adsorption sleeve. The roller column contacts the secondary permeation tank.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figures 1-9 One embodiment of the present invention is: a two-stage reverse osmosis device for the production of traditional Chinese medicine decoction pieces, comprising a frame 1, a high-pressure water pump 2 mounted on the frame 1, a primary osmosis tank 3 mounted on the frame 1, a valve pipe 4 fixedly connected to the top of the primary osmosis tank 3, a secondary osmosis tank 5 mounted on the frame 1, a rotating column 6 rotatably connected to the inner wall of the secondary osmosis tank 5, a motor disposed at the bottom of the secondary osmosis tank 5, a fixing rod 9 fixedly connected to the circumferential surface of the rotating column 6, and a fixing plate 10 fixedly connected to the bottom of the fixing rod 9. An ultraviolet lamp plate 11 is fixedly connected to the inner wall. An elastic telescopic rod 12 is fixedly connected to the bottom of the fixed plate 10. A rotating plate 13 is fixedly connected to the bottom of the ultraviolet lamp plate 11. A sealing plate 14 is fixedly connected to the telescopic end of the elastic telescopic rod 12. An open column 15 is fixedly connected to the inner wall of the rotating plate 13. An adsorption sleeve 16 is fixedly connected to the inner wall of the open column 15. A central bucket 17 is fixedly connected to the bottom of the rotating plate 13. An activated carbon plate 18 is fixedly connected to the inner wall of the central bucket 17. A reverse osmosis membrane is installed on the inner wall of the primary permeation tank 3. When the device is in use, the high-pressure water pump 2 will start synchronously, pumping liquid into the first-stage permeation tank 3. The reverse osmosis membrane inside the first-stage permeation tank 3 will then trap some contaminants in the liquid. The liquid will then enter the second-stage permeation tank 5 through valve pipe 4. At this point, the motor will start, and its output will drive the rotating column 6 to rotate. The rotation of the rotating column 6 will drive the fixed rod 9 to rotate, which in turn will drive the fixed plate 10 to rotate synchronously. The rotation of the fixed plate 10 will then drive the ultraviolet lamp plate 11 to rotate synchronously. As the UV lamp plate 11 rotates, it will be activated. During this rotation, the UV lamp plate 11 can eliminate disinfection blind spots, clean up bacteria in the water, ensure all-round sterilization of the water, improve the utilization rate of UV energy, and allow UV light to evenly sweep through every spatial dimension of the sterilizer cavity. All purified water flowing through it can be directly irradiated by UV light, completely eliminating blind spots and avoiding microbial residues caused by incomplete local sterilization. This improves the treatment effect and speed of the device on the water. The inner wall of the secondary permeation tank 5 is provided with a cleaning mechanism 7 for cleaning impurities, and the inner wall of the cleaning mechanism 7 is provided with a collection mechanism 8 for collecting impurities. The high-pressure water pump 2 is fixedly connected to the primary permeation tank 3 through a connecting pipe. The primary permeation tank 3 is connected to the valve pipe 4. The valve pipe 4 is fixedly connected to the secondary permeation tank 5. The rotating column 6 is fixedly connected to the output end of the motor. The sealing plate 14 is in contact with the rotating plate 13. The activated carbon plate 18 is in contact with the rotating column 6. The number of open columns 15 is set to multiple, and the multiple open columns 15 are arranged in a circular array on the inner wall of the rotating plate 13. The rotating plate 13 is in contact with the secondary permeation tank 5. When the device is in use, after the water is sterilized by the ultraviolet lamp plate 11, the water enters the open column 15 and passes through the adsorption sleeve 16 inside the open column 15 to reach the subsequent treatment area. During the process of the water passing through the adsorption sleeve 16, the adsorption sleeve 16 can intercept the microbial debris in the water. When a large amount of water enters the secondary permeation tank 5 at a high speed, the rotation of the fixed plate 10 will drive the sealing plate 14 to rotate. At the same time, the rotation of the fixed plate 10 will also drive the rotating plate 13 to rotate. The rotation of the rotating plate 13 will drive the central tank 17 to rotate. The rotation of the central tank 17 will... As the activated carbon plate 18 rotates, the impact force of the water will squeeze the sealing plate 14. The sealing plate 14 will then stretch the elastic telescopic rod 12 and move downward. During the downward movement of the sealing plate 14, the sealing plate 14 will open the opening of the central tank 17. At this time, some water will enter the central tank 17 through the open opening and be intercepted by the activated carbon plate 18 for microbial residues. This can increase the water treatment capacity, automatically match the demand for high water volume, improve the device's water treatment speed, and the torsion spring evenly distributes the water flow to avoid flow deviation and ensure the consistency of water treatment in each chamber. Overall working principle: The ultraviolet lamp plate 11 can eliminate disinfection blind spots, clean bacteria in the water, ensure all-round sterilization of the water, improve the utilization rate of ultraviolet energy, and allow ultraviolet light to evenly sweep through every spatial dimension of the sterilizer cavity. All purified water flowing through can be directly irradiated by ultraviolet light, completely eliminating blind spots and avoiding microbial residues caused by incomplete local sterilization. This improves the treatment effect and speed of the device on the water. A portion of the water will enter the central tank 17 through the open opening and be intercepted by the activated carbon plate 18 for microbial debris, which can increase the water treatment capacity and meet the demand for high water volume. The torsion spring evenly distributes the water flow, avoids flow deviation, and ensures the consistency of water treatment in each cavity.

[0016] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the cleaning mechanism 7 includes a toothed ring 701, a connecting block 702, a reciprocating screw 703, a gear 704, a limiting post 705, a moving plate 706, and a scraper ring 707. The toothed ring 701 is fixedly connected to the inner wall of the secondary permeation tank 5, the connecting block 702 is fixedly connected to the top of the rotating plate 13, the reciprocating screw 703 is rotatably connected to the inner wall of the connecting block 702, the gear 704 is fixedly connected to the circumferential surface of the reciprocating screw 703, the limiting post 705 is fixedly connected to the inner wall of the connecting block 702, the moving plate 706 is movably connected to the circumferential surface of the reciprocating screw 703, and the scraper ring 707 is fixedly connected to the inner wall of the moving plate 706. When the device is started, the rotation of the rotating plate 13 causes the connecting block 702 to rotate around the rotating column 6 as the rotation center. The rotation of the connecting block 702 causes the reciprocating screw 703 to rotate, which in turn causes the gear 704 to rotate. During the rotation of the gear 704, the gear 704 meshes with the gear ring 701. The gear ring 701 causes the gear 704 to rotate around itself as the rotation center while rotating around the rotating column 6. The rotation of the gear 704 causes the reciprocating screw 703 to rotate, which in turn causes the moving plate 706 to move forward. The moving plate 706 rotates, but at this time it is limited by the limiting post 705. The limiting post 705 causes the moving plate 706 to move up and down only through the reciprocating groove on the surface of the reciprocating screw 703 during the rotation of the reciprocating screw 703. The up and down movement of the moving plate 706 will drive the scraper ring 707 to move up and down synchronously. During the movement, the scraper ring 707 can scrape the microbial residue and fine particles on the surface of the adsorption sleeve 16, which can improve the utilization rate of the adsorption sleeve 16, improve the use effect of the device, and extend the service life of the device. The cleaning mechanism 7 also includes a second fixed rod 708, a roller column 709, a mixing plate 710, and a spiral fan blade 711. The second fixed rod 708 is fixedly connected to the circumferential surface of the rotating column 6. The roller column 709 is rotatably connected to the inner wall of the second fixed rod 708. The mixing plate 710 is fixedly connected to the circumferential surface of the roller column 709. The spiral fan blade 711 is fixedly connected to the circumferential surface of the roller column 709. The gear ring 701 meshes with the gear 704. The moving plate 706 is slidably connected to the circumferential surface of the limiting column 705. The scraper ring 707 contacts the adsorption sleeve 16 and is used to push the particles at the filter screen of the adsorption sleeve 16. The roller column 709 contacts the secondary permeation tank 5. The mixing plate 710 contacts the second fixed rod 708. When the device is started, food-grade reagents need to be added to the water. At this time, the rotation of the rotating column 6 will drive the fixed rod 708 to rotate, which in turn will drive the roller column 709 to rotate. The rotation of the roller column 709 will drive the mixing plate 710 to rotate, and simultaneously, the rotation of the roller column 709 will drive the spiral fan blade 711 to rotate. During the rotation of the roller column 709, the roller column 709 will generate corresponding friction due to contact with the secondary permeation tank 5 and during its movement. At this time, the roller column 709 will rotate around the rotating column 6 as the center of rotation, and the rotation of the roller column 709 will drive the spiral fan blade 711 to rotate as well. At the same time, the mixing plate 710 can also rotate synchronously. At this time, the mixing plate 710 can fully mix the water and the food-grade reagents, improve the water treatment speed, and enhance the efficiency of the device in water treatment. The collection mechanism 8 includes a push block 801, a hinge plate 802, a guide ring 803, and a collection box 804. The push block 801 is fixedly connected to the bottom of the moving plate 706. The hinge plate 802 is rotatably connected to the inner wall of the opening post 15 via a torsion spring. The guide ring 803 is fixedly connected to the inner wall of the opening post 15. The collection box 804 is fixedly connected to the bottom of the opening post 15. When the device is started, the movement of the moving plate 706 will drive the pushing block 801 to move synchronously. After the pushing block 801 moves downward a certain distance, it will contact the hinge plate 802 and push the hinge plate 802 to rotate. During the rotation, the hinge plate 802 can open the opening of the opening column 15. At the same time, as the moving plate 706 moves, it will push the microbial remains or trapped particles downward. While the hinge plate 802 opens the opening of the opening column 15, the particles can be guided into the collection box 804 through the inclined surface of the guide ring 803 for collection. This can improve the use effect of the device and reduce the manual cleaning cost. The collection mechanism 8 includes a sealing door 805, a groove plate 806, and a rotating block 807. The sealing door 805 is slidably connected to the inner wall of the collection box 804, the groove plate 806 is fixedly connected to the inner wall of the sealing door 805, and the rotating block 807 is rotatably connected to the inner wall of the sealing door 805. The hinge plate 802 is located on the movement trajectory of the push block 801. The groove plate 806 is in contact with the collection box 804, and the rotating block 807 is in contact with the collection box 804. Before using the device, the operator can manually push the sealing door 805 into the collection box 804. At this time, the movement of the sealing door 805 will drive the trough plate 806 to move, and at the same time, the movement of the sealing door 805 will drive the rotating block 807 to move. At this time, the trough plate 806 can be located inside the collection box 804 and can collect the particles that fall through the opening of the hinge plate 802. After the sealing door 805 is installed, the operator can manually rotate the rotating block 807. During the rotation, the rotating block 807 can limit the sealing door 805, which can achieve the effect of quick installation and fixation, improve the installation speed of the device, and indirectly improve the treatment effect of the device on water.

[0017] Overall working principle: The up-and-down movement of the moving plate 706 drives the scraper ring 707 to move up and down synchronously. During the movement, the scraper ring 707 scrapes away microbial debris and fine particles on the surface of the adsorption sleeve 16, improving the utilization rate of the adsorption sleeve 16, enhancing the effectiveness of the device, and extending its service life. The mixing plate 710 also rotates synchronously, fully mixing the water with the food-grade reagent, increasing the water treatment speed and improving the device's water treatment efficiency. When the hinge plate 802 opens the opening of the opening column 15, particles can be guided by the inclined surface of the guide ring 803 into the collection box 804 for collection, improving the device's effectiveness and reducing manual cleaning costs. During the rotation of the rotating block 807, the sealing door 805 is limited, enabling rapid installation and fixing, increasing the installation speed of the device, and indirectly improving the device's water treatment effect.
