[0033] Currently, mineralized filter cartridges on the market are generally made by mixing activated carbon and mineral materials in various ways. For example, mineral materials are filled into post-carbon filter cartridges, and carbon powder is mixed with mineral materials to prepare mineralized carbon rods. These mineralized filter cartridges generally have poor internal pores, resulting in poor mineralization effect and short service life. After continuous use for 3-6 months, their mineralization efficiency drops significantly, failing to meet people's long-term use needs. This leads to frequent filter cartridge replacement cycles and an average annual maintenance cost of about 500 RMB, which not only increases the economic burden on users but also wastes resources.
[0034] Therefore, please refer to Figure 1-7 This utility model protects a highly durable mineralized filter cartridge system, comprising:
[0035] The first purification section 100, the second purification section 200, and the mineralization section 300 are connected in sequence.
[0036] The first purification unit 100 includes a first housing 10 and a primary purification filter element 11. The first housing 10 has a first water inlet 12 and a first water outlet 13. The first housing 10 is provided with a first water passage chamber 14 and a first water collection chamber 15. The first water passage chamber 14 is connected to the first water inlet 12, and the first water collection chamber 15 is connected to the first water outlet 13. The primary purification filter element 11 is coaxially sleeved on the outside of the first water passage chamber 14.
[0037] The second purification unit 200 includes a second housing 20 and a secondary purification filter element. The second housing 20 has a second water inlet 21 and a second water outlet 22. The second housing 20 is provided with a second water passage chamber 23 and a second water collection chamber 24. The second water passage chamber 23 is connected to the second water inlet 21, and the second water collection chamber 24 is connected to the second water outlet 22. The secondary purification filter element is coaxially sleeved on the outside of the second water passage chamber 23.
[0038] The mineralization section 300 includes a third housing 30. The interior of the third housing 30 is provided with a first mineralization chamber, a second mineralization chamber 32, and a third mineralization chamber 33 in sequence along the water flow direction. The first mineralization chamber, the second mineralization chamber 32, and the third mineralization chamber 33 are sequentially filled with a first mineralization filter element 34, a second mineralization filter element 35, and a third mineralization filter element 36. The first mineralization chamber is connected to the third inlet 37 of the third housing 30, and the third mineralization chamber 33 is connected to the third outlet 38 of the third housing 30.
[0039] A first temperature control unit 40 and a first temperature monitoring unit 41 are respectively provided at the first water inlet 12. A second temperature control unit 42 is provided on the pipeline connecting the first water outlet 13 and the second water inlet 21. A second temperature monitoring unit 43 is provided at the second water inlet 21. The first temperature control unit 40, the first temperature monitoring unit 41, the second temperature control unit 42 and the second temperature monitoring unit 43 are all connected to the controller signal.
[0040] In this invention, the first purification section 100, the second purification section 200, and the mineralization section 300 are all connected sequentially via pipelines. The first housing 10, the second housing 20, and the third housing 30 are all cylindrical structures. The primary purification filter element 11 is an ultrafiltration membrane filter element, and the secondary purification filter element consists of a reverse osmosis membrane 25 and an activated carbon fiber filter element 26, with the reverse osmosis membrane 25 and the activated carbon fiber filter element 26 arranged sequentially along the permeation direction of the water to be purified.
[0041] After the purified water enters the first water passage chamber 14, it undergoes primary purification under the action of the primary purification filter element 11 and then enters the first water collection chamber 15. It then flows from the first water outlet 13 into the second water passage chamber 23, undergoes secondary purification under the action of the secondary purification filter element, and then enters the mineralization section 300. The purification process of the purified water is then completed.
[0042] The first mineralized filter element 34 includes maifan stone. The maifan stone is crushed and screened to obtain particles with a diameter of 1-3 mm. It is then washed and dried. The resulting maifan stone particles are placed in a high-temperature environment of 700℃ for 2 hours to obtain activated maifan stone. The activated maifan stone is then cooled to obtain the maifan stone particles. The natural maifan stone of this invention, after specific treatment, has an increased specific surface area, and high-temperature calcination can improve the dissolution effect of the maifan stone.
[0043] The second mineralization filter element 35 includes wollastonite. The wollastonite is mixed evenly with hydrochloric acid, water is added and stirred, and the mixture is allowed to stand for a period of time. After filtration, washing, and drying, heavy metal-free wollastonite is obtained. The heavy metal-free wollastonite is then crushed and ball-milled to obtain wollastonite powder. The powder is then shaped to obtain porous wollastonite blocks. These porous wollastonite blocks are then crushed and sieved to obtain the final porous wollastonite particles with a particle size of 0.5 mm. Natural wollastonite has few internal pores and a smooth surface. Crushing, ball milling, reshaping, crushing, and sieving can increase the internal pore size and specific surface area of the ore.
[0044] The third mineralization filter element 36 comprises calcite and basalt. The calcite is washed, dried, crushed, ball-milled, and sieved to obtain calcite particles with a specific surface area of 2.723 m². 2 / g. The basalt is mixed with hydrochloric acid, heated and stirred, allowed to stand for a period of time, filtered, washed, and dried to obtain heavy metal-free basalt. The heavy metal-free basalt is then crushed, ball-milled, and sieved. The resulting basalt particles are placed in a high-temperature environment of 500℃-700℃ for 2 hours and cooled to obtain the basalt particles with a particle size of less than 0.1mm. Calcite itself has abundant internal pores; crushing, ball milling, and sieving increase the specific surface area of the ore. Natural basalt, after high-temperature calcination, has increased internal porosity; crushing, ball milling, and sieving further increase the specific surface area of the ore.
[0045] In this invention, the first temperature control unit 40 is an electrical component with heating function, such as a heater; the second temperature control unit 42 is an electrical component with water cooling function, such as a condenser; and the first temperature monitoring unit 41 and the second temperature monitoring unit 43 are temperature sensors. The controller controls the first temperature control unit 40 and the second temperature control unit 42 to heat or cool the water to be purified. The first temperature monitoring unit 41 and the second temperature monitoring unit 43 detect the heating temperature of the water to be purified. The coordinated operation of the first temperature control unit 40, the second temperature control unit 42, the first temperature monitoring unit 41, and the second temperature monitoring unit 43 achieves the regulation of the temperature of the water to be purified.
[0046] The filter system of this utility model can sequentially perform primary purification, secondary purification and multi-stage mineralization treatment on the water to be purified. It can effectively remove organic matter and large molecular impurities from the water, improve the water purification effect and extend the service life of the mineralization filter. Specifically, the first temperature control unit 40 maintains the temperature of the water to be purified at or above 90°C. At this temperature, microplastics in the water precipitate together with calcium carbonate. The microplastics are then immediately removed by the first-stage purification filter 11. The water purified by the first-stage purification filter 11 passes through the second temperature monitoring unit 43, which collects temperature data and transmits it to the controller. The controller controls the second temperature control unit 42 to adjust the temperature so that the temperature of the water entering the second-stage purification filter is within the range of 26°C to 45°C. This temperature range can appropriately improve the purification effect of the activated carbon fiber and ensure the normal operation of the reverse osmosis membrane 25. The water to be purified has had dissolved salts, organic matter, microorganisms, etc. removed by the first-stage and second-stage purification filters, and the effluent quality is close to pure water. The water that has passed through the first-stage and second-stage purification filters is then passed through the mineralization filter. Because the water does not contain organic matter and large molecular impurities, it has little impact on the mineralization filter and can extend the service life of the mineralization filter. Meanwhile, the mineralization filter element of the mineralization section 300 of this utility model has undergone specific treatment of the mineralization materials. Different treatment methods are used for different ores to ensure that the mineralization effect of each treated ore is the most stable. This can achieve the effect of extending the service life of the purification-mineralization filter element, meeting the user's needs, thereby reducing maintenance costs, reducing the user's economic burden and resource waste.
[0047] In another embodiment of this utility model, the first water passage chamber 14 is composed of multiple layers of stainless steel mesh, and the pore size of the multiple layers of stainless steel mesh decreases sequentially along the permeation direction of the water to be purified. Similarly, the second water passage chamber 23 is composed of multiple layers of stainless steel mesh, and the pore size of the multiple layers of stainless steel mesh decreases sequentially along the permeation direction of the water to be purified. In this way, particulate impurities in the water to be purified are filtered through the multiple layers of stainless steel mesh, avoiding affecting the service life of the primary purification filter element 11 and the secondary purification filter element. At the same time, the multiple layers of stainless steel mesh provide support, reducing the damaging effect of water pressure on the primary purification filter element 11 and the secondary purification filter element, and extending the life of the filter element.
[0048] In another embodiment of this utility model, the first mineralization chamber, the second mineralization chamber 32, and the third mineralization chamber 33 are three independent chambers. The first mineralization chamber, the second mineralization chamber 32, and the third mineralization chamber 33 are separated by a water-permeable but non-permeable ore material isolation material, such as a screen, to reduce interference during ore leaching, reduce the interaction between different types of ores during leaching, and ensure that each type of ore has the best leaching effect and the longest continuous leaching time.
[0049] In another embodiment of this utility model, a partition 39 is provided inside the first mineralization chamber. The partition 39 is arranged along the flow direction of the water to be purified, and the partition 39 divides the first mineralization chamber into two independent and symmetrical mineralization chambers 31, each of which is filled with the first mineralization filter element 34. Preferably, the partition 39 is made of a waterproof material, such as food-grade polypropylene (PP).
[0050] In another embodiment of this utility model, there are two mineralization sections 300, and the two mineralization sections 300 are arranged in parallel and connected to the second purification section 200; the third inlet 37 and the third outlet 38 of each mineralization section 300 are respectively provided with a first water flow switch 301 and a second water flow switch 302, and the water inlet end of the first mineralization chamber is provided with a mineralization switch 303.
[0051] In this invention, by periodically controlling the switching of the first water-passing switch 301, the second water-passing switch 302, and the mineralization switch 303 of the two mineralization sections 300, the alternating operation of different mineralization sections 300 and the mineralization filtration of different mineralization chambers 31 within the same mineralization section 300 are initiated. This achieves the goal of controlling the leaching time of the mineralization material in each mineralization filter element of the mineralization section 300, implementing intermittent leaching of the ore, improving the continuity of ore leaching, and extending the service life of the mineralization filter elements. Specifically:
[0052] First, by controlling the opening of the first water flow switch 301, mineralization switch 303, and second water flow switch 302 of one mineralization section 300, and controlling the corresponding switch of the other mineralization section 300 to close, the purified water enters one of the mineralization chambers 31 of the first mineralization chamber through the third inlet 37, and undergoes mineralization treatment by passing through the first mineralization filter element 34, the second mineralization filter element 35, and the third mineralization filter element 36 in sequence, and then flows out from the third outlet 38 of the mineralization section 300. After three hours, the first water flow switch 301 and the second water flow switch 302 of the mineralization section 300 are closed, and the first water flow switch 301 and the second water flow switch 302 of the other mineralization section 300 are started, and the purified water flows through the other mineralization section 300 for mineralization treatment. Thus, with a three-hour exchange cycle, the two mineralization sections 300 are used alternately. At the same time, the mineralization switch 303 of the mineralization section 300 is activated to adjust the alternating use of the two mineralization chambers 31 of the mineralization section 300. The above process is repeated to achieve the alternation of use of the two mineralization sections 300 and the two mineralization chambers 31 of the mineralization section 300 every three hours.
[0053] In another embodiment of this utility model, the first water switch 301 includes a rotating shaft 3011 and a cover 3012. The rotating shaft 3011 is rotatably mounted at the third water inlet 37, and the cover 3012 is connected and fixed to the rotating shaft 3011. When the rotating shaft 3011 rotates, it can drive the cover 3012 to open or close the third water inlet 37.
[0054] In this invention, the first water-passing switch 301 is installed in a pipeline structure connected to the third water inlet 37, wherein the cover 3012 is adapted to the size of the pipeline. The cover 3012 is a circular plate structure with a sealing strip 3013 circumferentially provided, and the sealing strip 3013 is made of EPDM rubber. Preferably, both sides of the cover 3012 are provided with stainless steel mesh, and the surface of the stainless steel mesh and the rotating shaft 3011 are treated with a nano-coating for waterproofing. The nano-coating is waterproof, which can protect the switch structure without affecting the switch function, and prevent mechanical damage, chemical corrosion and other substances from the switches. In order to realize intelligent control of the first water-passing switch 301, the rotating shaft 3011 is driven by a drive motor, which is electrically connected to the controller, and the controller controls the drive motor to drive the rotation of the rotating shaft 3011. Ideally, the controller controls the rotating shaft 3011 to rotate 45° clockwise, which in turn drives the cover 3012 to rotate 45° clockwise, so that the cover 3012 forms a 135° angle with the direction of water flow. This design, combined with the stainless steel mesh, can reduce the impact of water flow and reduce the wear and tear on the switch, thereby extending the service life of the switch and reducing maintenance costs.
[0055] In another embodiment of this utility model, the second water switch 302 includes a rotating shaft 3021 and a cover plate 3022. The rotating shaft 3021 is rotatably installed at the third water outlet 38. The cover plate 3022 has a semi-circular structure, and there are two cover plates 3022. The two cover plates 3022 are symmetrically installed along the rotating shaft 3021 and are rotatably connected to the rotating shaft 3021.
[0056] In this invention, the second water-passing switch 302 is installed on the pipeline at the third water outlet 38. The circular plate structure formed by the two cover plates 3022 is adapted to the size of the pipeline at that location. A sealing strip 3023, made of EPDM rubber, is provided circumferentially on each cover plate 3022. The rotating shaft 3021 is driven by a drive motor, which is electrically connected to a controller. The controller controls the drive motor to drive the rotation of the rotating shaft 3021, causing the two cover plates 3022 on the left and right sides to rotate 90° counterclockwise and clockwise, respectively. The cover plate 3022, the rotating shaft 3021, and the electrical connection between the drive motor and the controller are all treated with a nano-coating for waterproofing. In this way, the nano-coating is waterproof, which can protect the switch structure without affecting the switch function, prevent mechanical damage, chemical corrosion, and other substances from eroding the switches, and thus extend the service life of the switches. Furthermore, the cover plate 3022 can be rotated 90° to reduce the obstruction to water flow and prevent water from staying in the mineralization cavity for too long, thereby achieving continuous leaching of the ore and extending the service life of the ore.
[0057] In another embodiment of this utility model, the mineralization switch 303 includes a support frame 3031, a rotating plate 3032, and a rotating disk 3033. The first mineralization chamber is a cylindrical structure. The support frame 3031 is adapted to the first mineralization chamber and has 3034 evenly distributed on it. The support frame 3031 is coaxially installed at the water inlet end of the first mineralization chamber. The rotating plate 3032 is a semi-circular structure, which is coaxially arranged with the support frame 3031 and rotatably connected to the support frame 3031 through the rotating disk 3033. The rotating disk 3033 drives the rotating plate 3032 to rotate to cover or open any of the mineralization chambers 31.
[0058] In this invention, four 3034s are provided, with two 3034s corresponding to and connected to one mineralization chamber 31. Similarly, the rotating disk 3033 is automatically rotated by a servo motor and a controller. The controller controls the rotating disk 3033 to rotate 180° clockwise to block any set of 3034s connected to the mineralization chamber 31, thereby achieving the connection and closure of two mineralization chambers 31. Similarly, the rotating disk 3033 and its electrical connection with the controller are treated with a nano-coating for waterproofing.
[0059] This utility model also protects a water purification device, which includes: a shell, in which an inlet pipe and an outlet pipe are provided, and the aforementioned mineralization filter system, wherein the mineralization filter system is connected to the inlet pipe and the outlet pipe respectively.
