Description

Technical Field

[0002] Silicon (Si) is one of the essential trace elements for the human body as defined by the World Health Organization. Silicon rarely exists alone in nature; it is generally found widely in rocks, gravel, and water bodies in the form of complex silicates (such as aluminosilicates) or silicon dioxide. In water, silicon dioxide itself has extremely low solubility, but under certain conditions it can form water-soluble metasilicic acid and orthosilicic acid, which are the most basic forms of silicic acid in water. Metasilicic acid has a significant impact on the taste and nutritional value of water. Studies show that metasilicic acid is beneficial to human bone and cardiovascular health, promoting bone development and reducing the risk of cardiovascular disease. One ideal way for the human body to obtain silicon is through drinking water; however, the metasilicic acid content in ordinary water bodies is usually limited. Current metasilicic acid filter cartridges dissolve silicon very slowly, making it difficult to guarantee the metasilicic acid content in the water. Summary of the Invention

Therefore, they should not be construed as limitations on the invention. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0038] The various specific technical features and embodiments described in the detailed embodiments can be combined in any suitable manner without contradiction. For example, different implementation methods can be formed by combining different specific technical features / embodiments. In order to avoid unnecessary repetition, the various possible combinations of the various specific technical features / embodiments in this invention will not be described separately.

[0039] This invention provides a filter cartridge design method, including the following steps: designing a metasilicic acid filter material 200 and a filter material 100 that can form hydroxide ions in water; designing a water flow that passes sequentially or simultaneously through the filter material 100 and the metasilicic acid filter material 200; the corresponding basic water system can be referenced. Figure 1 This process allows hydroxide ions, which promote the formation of the filter material 100, to act on the metasilicic acid filter material 200, thereby promoting the formation of metasilicic acid (H2SiO3) in the water. Metasilicic acid is produced by the hydrolysis of silicate minerals in water. Taking sodium silicate (Na2SiO3) as an example, SiO3... 2- +H2O H₂SiO₃ + 2OH⁻ - H2SiO3 + H2O H₄SiO₄ exists, but metasilicic acid and orthosilicic acid (H₄SiO₄) exist in a dynamic equilibrium. Orthosilicic acid is a strong acid and can exist stably in acidic environments. Therefore, in alkaline environments (water containing a certain concentration of hydroxide ions), H₂SiO₃ + H₂O will precipitate. The equilibrium of H4SiO4 shifts to the left, meaning the content of orthosilicic acid decreases and the concentration of metasilicic acid increases. In this invention, the promoting filter material 100 is positioned upstream of the metasilicic acid filter material 200, allowing water to flow sequentially through both materials. Alternatively, the promoting filter material 100 and the metasilicic acid filter material 200 can be placed in the same filter chamber, allowing water to flow simultaneously through both materials. The hydroxide ions formed by the promoting filter material 100 are utilized. The water containing hydroxide ions acts on the metasilicic acid filter material 200, thereby promoting the dissolution rate of silicon in the metasilicic acid filter material 200. The concentration of metasilicic acid formed in the water is relatively high, especially in high-flow scenarios. By promoting the effect of filter material 100 on metasilicic acid filter material 200, the metasilicic acid content in the water produced by the water purifier can meet the set requirements. When the metasilicic acid content is high, the drinking water tastes better and has more health benefits for users, resulting in a better user experience.

[0040] Optionally, the filter media 100 is designed to be alkaline and is used to adjust the pH of the water flow to 7.0 to 9.0. Excessive alkalinity in the water will inhibit the hydrolysis of silicate ions, thereby reducing the formation of metasilicic acid. Therefore, an appropriate alkalinity can promote the formation of metasilicic acid, while excessive alkalinity or acidity will reduce the formation of metasilicic acid.

[0041] The filter media 100 can be an alkaline mineral. The mass percentage of the filter media 100 refers to the mass of the filter media 100 / (mass of the filter media 100 + mass of the metasilicic acid filter media 200). Table 1 shows the effect of different water pH values ​​(corresponding to different proportions of the filter media 100) on the metasilicic acid content in the filter element. The metasilicic acid concentration after running water and soaking for 1 hour when the mass percentage of the filter media 100 (alkaline mineral) is 20%-40% (corresponding to different water pH values) is shown in Table 1.

[0042] Table 1

[0043]

[0044] As shown in Table 1, when the alkaline ore content is 0%, the flowing water is weakly acidic (pH 6.2) with a very low metasilicic acid concentration of only 0.2 mg / L. When the alkaline ore content increases to 10%, the flowing water becomes weakly alkaline (pH 7.1) with a slightly increased metasilicic acid concentration. When the alkaline ore content is between 20% and 40%, the metasilicic acid concentration in the flowing water is above 2 mg / L. When the alkaline ore content is 30%, the metasilicic acid concentration in the soaking water can reach up to 10 mg / L. When the alkaline ore content is 50%, the pH of the flowing water becomes too high (pH 9.3), and its effect on promoting metasilicic acid formation begins to decrease. In practical applications, the metasilicic acid concentration can be further increased by increasing the surface area of ​​the metasilicic acid filter material 200.

[0045] It is evident that adjusting the pH of the flowing water to 7.0 to 9.0 can effectively promote the formation of metasilicic acid and prevent excessively high pH levels in the water. In practical applications, the pH of the flowing water can be adjusted to 7.9 to 8.8 through water circuit design and control, preferably to around 8.5. In practical applications, two or more alkaline filters can be connected in parallel, one being a strongly alkaline filter and the other a weakly alkaline filter. By controlling the mixing of the two alkaline water circuits, the pH of the flowing water can be adjusted to 8.5. Furthermore, the pH of the flowing water passing through the filter can be adjusted to a stable range, promoting a longer filter lifespan and avoiding the decrease in alkalinity that occurs with prolonged use of a single alkaline filter. In practical applications, the proportion of alkaline minerals can be adaptively adjusted according to the quality of the minerals and other materials to ensure the pH of the flowing water is adjusted to the set range.

[0046] The present invention also provides a filter element, which can be designed by the above-described design method. The filter element includes a metasilicic acid filter material 200 that can form metasilicic acid in water and a promoting filter material 100 that can form hydroxide ions in water. The promoting filter material 100 is used to form hydroxide ions in water. The hydroxide ions can be used to promote the formation rate of metasilicic acid in the metasilicic acid filter material 200 in water. The water containing hydroxide ions (alkaline water) acts on the metasilicic acid filter material 200, thereby promoting the dissolution rate of silicon in the metasilicic acid filter material 200. The concentration of metasilicic acid formed in the water is relatively high, especially in high flow rate scenarios. Through the promoting effect of the promoting filter material 100 on the metasilicic acid filter material 200, the metasilicic acid content in the water can meet the set requirements.

[0047] In specific applications, the filter media 100 is an alkaline filter media, and the pH value of the water flowing through the filter media 100 can be between 7.1 and 9.0. The filter media 100 may include at least one of brucite, periclase, calcite, and dolomite; the metasilicic acid filter media 200 includes at least one of diopside, serpentine, and maifanite.

[0048] Specifically, the materials of the facilitator filter media 100 and the metasilicic acid filter media 200 are mixed and then cured to form a one-piece filter element for easy assembly. In specific applications, the filter element can be in the shape of a single carbon rod. Alternatively, the facilitator filter media 100 and the metasilicic acid filter media 200 can be integrally connected along a predetermined direction. For example, the facilitator filter media 100 and the metasilicic acid filter media 200 can be arranged vertically along the axial direction of the filter cartridge, or they can be arranged radially inward and outward along the radial direction of the filter cartridge. Specifically, the facilitator filter media 100 is positioned upstream of the metasilicic acid filter media 200, making the water flowing through the metasilicic acid filter media 200 alkaline.

[0049] Specifically, the filter media 100 and the metasilicic acid filter media 200 can also be separately molded and connected by assembly. Specifically, the filter media 100 and the metasilicic acid filter media 200 can be fixedly connected along a predetermined direction through methods such as bonding, end cap connection, or central tube connection. The carriers of the filter media 100 and the metasilicic acid filter media 200 can be the same or different. The filter media 100 and the metasilicic acid filter media 200 can also be separately arranged along a predetermined direction, that is, the filter media 100 and the metasilicic acid filter media 200 can be separately installed in different filter cartridges, or the filter media 100 and the metasilicic acid filter media 200 can be connected in series in the water circuit.

[0050] Specifically, the filter element has a matrix made of carbon material in the shape of carbon rods. The materials of filter media 100 and metasilicic acid filter media 200 are mixed with the carbon material and then sintered to form a monolithic structure. The carbon material can be carbon powder or adhesive powder. After molding, the filter element can be in the shape of a cylindrical carbon rod, allowing water to flow through it axially or radially. Alternatively, the filter element can be in the shape of a cylindrical carbon rod, allowing water to flow through it radially.

[0051] Alternatively, the filter element may have an integral substrate, which may be carbon rod filter media, carbon fiber filter media, carbon granule filter media, or ceramic filter media. The materials of the facilitator filter media 100 and the metasilicic acid filter media 200 may be attached to the substrate. For example, when the substrate is carbon rod filter media, the facilitator filter media 100 and the metasilicic acid filter media 200 may be attached to or dispersed on the upper and lower portions of the carbon rod filter media, respectively (see reference). Figure 3 (As shown), or, the filter media 100 and the metasilicic acid filter media 200 can also be arranged radially inside and outside or outside and inside along the carbon rod filter media (see reference). Figure 4 (As shown). When the matrix is ​​carbon fiber filter media, the promoting filter media 100 and the metasilicic acid filter media 200 are respectively disposed on the same side of the carbon fiber filter media. The promoting filter media 100 and the metasilicic acid filter media 200 can be arranged in layers along the length or width direction of the carbon fiber filter media. Of course, the promoting filter media 100 and the metasilicic acid filter media 200 can also be disposed on the front and back sides of the carbon fiber filter media respectively. The carbon fiber filter media can be wound into a columnar or cylindrical shape.

[0052] Alternatively, the filter element may have a separate first substrate and a second substrate. The first substrate may be a carbon rod filter material, carbon fiber filter material, carbon granule filter material, or ceramic filter material, and the second substrate may be a carbon rod filter material, carbon fiber filter material, carbon granule filter material, or ceramic filter material. The filter material 100 is attached to the first substrate, and the metasilicic acid filter material 200 is attached to the second substrate. The first substrate and the second substrate are connected along the axial or radial direction of the filter element. That is, the first substrate can be a carbon rod, and the second substrate can be a carbon fiber filter material (in rolls), etc., or the first substrate can be a carbon fiber filter material (in rolls), and the second substrate can be a carbon granule filter material, etc. Specific combinations will not be elaborated here.

[0053] Optionally, in the filter media 100 and the metasilicic acid filter media 200, the mass proportion of the filter media 100 is 20% to 40% to adjust the pH value of the flowing water to a set range. In specific applications, a pH sensor can be installed in the water circuit. The pH sensor is downstream of the filter media 100 and upstream of the metasilicic acid filter media 200. Through flow control, the pH value of the water effluent from the filter media 100 can be adjusted to a set range, which is beneficial for promoting the formation of metasilicic acid in the water by the metasilicic acid filter media 200.

[0054] The present invention also provides a method for preparing a filter element, which includes the following steps:

[0055] Prepare alkaline and silicate ores and perform cleaning and drying treatments;

[0056] The alkaline and silicate ores are crushed to a set particle size (the particle size can be 100-400 mesh).

[0057] Alkaline ores and silicate ores are mixed with a matrix material and then molded into a single filter element; alternatively, alkaline ores and silicate ores are mixed separately with the matrix material and then molded into separate filter elements. The mass ratio of alkaline ores to silicate ores can be 3:7, which is beneficial for promoting the formation of metasilicic acid.

[0058] Optionally, the alkaline ore includes at least one of brucite, periclase, calcite, and dolomite; the silicate ore includes at least one of diopside, serpentine, and maifanite. The alkaline ore and silicate ore respectively form alkaline filter material and metasilicic acid filter material 200.

[0059] The present invention also provides a filter cartridge, such as Figure 3 and Figure 4 As shown, it includes a filter cartridge housing 400, and the filter cartridge housing 400 is provided with the above-mentioned filter element (promoting the filter media to be alkaline filter media).

[0060] Optionally, a filter chamber is provided inside the filter cartridge housing 400, and the filter elements (promoting filter material 100 and metasilicic acid filter material 200) are arranged in the same filter chamber. After the water enters the filter chamber, alkaline water is formed in the filter chamber. The alkaline water directly acts on the metasilicic acid filter material 200 to promote the formation of metasilicic acid. The filter element can be an integral structure or a split structure.

[0061] Alternatively, the filter housing 400 may contain a first filter chamber and a second filter chamber connected in series along the water flow direction. The facilitator filter media 100 is disposed in the first filter chamber, and the metasilicic acid filter media 200 is disposed in the second filter chamber. Water flowing into the first filter chamber forms alkaline flow water. This alkaline flow water then passes through the metasilicic acid filter media 200 in the second filter chamber, promoting the formation of metasilicic acid in the water. In some optional solutions, the first and second filter chambers can also be switched to parallel connection, meaning the water flow can be switched as needed to flow separately through the facilitator filter media 100 (alkaline filter media) and the metasilicic acid filter media 200 to meet different water usage requirements.

[0062] This invention also provides a water system, including an inlet pipe 310 and an outlet pipe 320. A metasilicic acid water treatment system 330 is provided between the inlet pipe 310 and the outlet pipe 320, and the metasilicic acid water treatment system 330 is equipped with one of the aforementioned filter elements. The inlet pipe 310 can be connected to an RO filter element. The outlet pipe 320 can be connected to a faucet, etc. The filter element of the metasilicic acid water treatment system 330 includes a promoting filter material 100 and a metasilicic acid filter material 200. Water flows sequentially or simultaneously through the promoting filter material 100 and the metasilicic acid filter material 200. Utilizing the hydroxide ions formed by the promoting filter material 100, the water containing hydroxide ions acts on the metasilicic acid filter material 200, thereby promoting the rate at which the metasilicic acid filter material 200 forms metasilicic acid in the water, and thus increasing the concentration of metasilicic acid in the water. Metasilicic acid is known as "gold in water," and its concentration is generally considered to be better the higher it is within the limit.

[0063] Specifically, the metasilicic acid water production circuit 330 has a filter element installation cavity, which promotes the filter media 100 and the metasilicic acid filter media 200 to be arranged in the same filter element installation cavity along the water flow direction. The inlet pipe 310 and the outlet pipe 320 are connected to the filter element installation cavity, which promotes the filter media 100 and the metasilicic acid filter media 200 to be integrated or fixedly connected. Its water circuit and structure are simple and reliable, and it is also convenient for the installation and maintenance of the filter element.

[0064] Alternatively, the filter media 100 and the metasilicic acid filter media 200 can be arranged in different filter cartridge installation cavities of the metasilicic acid water production channel 330 along the preset water flow direction. That is, the filter media 100 and the metasilicic acid filter media 200 can be set separately. When the alkalinity of the filter media 100 decreases, the filter media 100 can be replaced individually, resulting in low application cost.

[0065] The present invention also provides a mineral water purifier, which is equipped with the above-mentioned water system or the above-mentioned filter element.

[0066] Optionally, the mineral water purifier also includes a pure water path 340, with one end of the pure water path 340 connected to the inlet pipe 310 and the second end of the pure water path 340 connected to the outlet pipe 320 (e.g., Figure 2 (as shown), or, the second end of the pure water circuit 340 is connected to the pipeline between the filter media 100 and the metasilicic acid filter media 200, and the pH value or the concentration of metasilicic acid in the outlet water can be adjusted through the pure water circuit 340 to meet the personalized needs of different users.

[0067] Optionally, a water quality sensor 412 is installed downstream of the metasilicic acid filter media 200. The water quality sensor is a pH sensor and / or a TDS sensor. Of course, a water quality sensor 411 can also be installed upstream of the filter media 100. In specific applications, the metasilicic acid water treatment circuit 330 and the pure water circuit 340 can be equipped with flow meters and flow control valves to adjust the mineral (metasilicic acid) content and pH value of the effluent according to requirements.

[0068] Optionally, the pure water circuit 340 and the metasilicic acid water production circuit 330 are connected to an inlet flow control valve. The inlet flow control valve is electrically connected to the control module. The control module adjusts the inlet flow control valve according to the set water output requirements to adjust the water volume passing through the metasilicic acid water production circuit 330 and the pure water circuit 340, so that the concentration of metasilicic acid can be adjusted.

[0069] The present invention provides a filter element and its design, preparation method, filter cartridge, water system, and mineralization water purifier. By setting up a filter promoting material 100 and a metasilicic acid filter material 200, water flows sequentially or simultaneously through the filter promoting material 100 and the metasilicic acid filter material 200. Utilizing the hydroxide ions formed by the filter promoting material 100, the water containing hydroxide ions acts on the metasilicic acid filter material 200, thereby promoting the dissolution rate of silicon in the metasilicic acid filter material 200. The concentration of metasilicic acid formed in the water is relatively high, especially in high-flow scenarios. Through the promoting effect of the filter promoting material 100 on the metasilicic acid filter material 200, the metasilicic acid content in the water can meet the set requirements.
