Description

Technical Field

[0001] The present application relates to the technical field of mineral water production, and in particular to a method and device for producing composite natural mineral water. Background Art

[0002] Natural mineral water is uncontaminated underground water that springs naturally from deep underground or is artificially exposed. It contains a certain amount of mineral salts, trace elements, or carbon dioxide gas. Under normal circumstances, its chemical composition, flow rate, water temperature, and other dynamics are relatively stable within the natural fluctuation range. When processing this natural mineral water into drinking mineral water, it needs to be treated in accordance with the mineral content and limit indicators specified by national standards. In particular, when a certain mineral is missing in the natural mineral water or the content does not meet the national standard, it is necessary to add minerals to the raw water.

[0003] In the related art, a Chinese patent application with application number CN202011456365.7 proposes a method and device for producing composite natural mineral water. The composite natural mineral water production device includes a dedicated metasilicic acid filter material device, which includes three layers: a zinc filter layer, a selenium filter layer, and a strontium filter layer. The zinc filter layer is arranged above the selenium filter layer, and the selenium filter layer is located in the middle. The source water passes through the zinc filter layer, the selenium filter layer, and the strontium filter layer in sequence before flowing out. The device of this application has a simple structure and can allow trace elements to be contained in the water, improving the quality of the mineral water.

[0004] The above-mentioned related technologies have the following defects: pure minerals are combined in the filter material to form a stable complex. This material has good durability and biocompatibility. Raw water flows through the filter material containing mineral elements, thereby carrying out the required minerals, and the release rate and proportion of the mineral elements can be precisely controlled. However, this filter material is generally set up as a whole. When the water flow rate on the production line remains unchanged, it is difficult to dynamically control the release amount of mineral elements to meet the situation of unstable mineral element content in the raw water. At the same time, different minerals have different diffusion rates in the raw water. In the process of raw water passing through the filter material and carrying out minerals, the local dissolution concentration of minerals in the filter material will vary, resulting in uneven distribution of minerals in the raw water. Summary of the Invention

[0005] In order to improve the problem of difficulty in dynamically controlling the amount of minerals added to raw water and the difference in mineral concentration after adding minerals, the present application provides a method and apparatus for producing composite natural mineral water.

[0006] The first aspect of the present application provides a composite natural mineral water production device that adopts the following technical solution: A composite natural mineral water production device includes an outer water storage tank and an inner water inlet tank, wherein the inner water inlet tank is provided with a water inlet pipe, the outer water storage tank is provided with a water outlet pipe, the inner water inlet tank is arranged in the outer water storage tank, and between the inner water inlet tank and the outer water storage tank is provided: There are several water risers, each of which has an elliptical cross section and is fixedly connected to the outer water storage tank at both ends.

A water outlet channel, an acceleration channel and a flaring channel are formed between the outer wall of the inner water inlet tank and the inner wall on the long axis side of the innermost water riser, between the inner and outer walls of the outer and inner water risers on the long axis side of the two, and between the inner wall of the water storage tank and the outer wall on the long axis side of the outermost water riser.

[0007] Furthermore, a plurality of first spoilers extending in the raw water flow direction are installed on the outer wall of the water inlet inner tank and the outer wall of the water barrier corresponding to the adjacent portions of the flared flow channel; A plurality of second spoilers extending along the raw water flow direction are installed at locations corresponding to the adjacent flared flow channels on the inner wall of the water storage outer tank and the inner wall of the water barrier.

[0008] Furthermore, in the same flared flow channel, the amount of flow reduction of the flared flow channel caused by the second spoiler is greater than the amount of flow reduction of the flared flow channel caused by the first spoiler.

[0009] Furthermore, in the same flared flow channel, the plurality of second spoilers and the plurality of first spoilers on the same horizontal plane are arranged in a staggered manner.

[0010] Furthermore, the plurality of first spoilers and the plurality of second spoilers are arranged in multiple groups along the axial direction of the water inlet inner tank, and two adjacent groups of first spoilers are staggered on the horizontal plane, and two adjacent groups of second spoilers are staggered on the horizontal plane.

[0011] Furthermore, diverter plates are installed on the inner wall of the water barrier and the inner wall of the water storage outer tank corresponding to the adjacent water outlet channels. The diverter plate has a pointed end in the middle of the side facing the adjacent water outlet, and the pointed end has a diverter curved surface extending toward the side of the diverter plate; the diverter curved surface is used to guide the raw water to the two acceleration channels on both sides.

[0012] Furthermore, the dynamic adjustment mechanism includes: A plurality of samplers are provided and are arranged in a one-to-one correspondence with the plurality of water outlets, and the sampler is arranged downstream of the water outlet and between two corresponding outlets of the flared flow channel; Trace element concentration detector, used to detect the target mineral concentration in the sample water extracted by the sampler; a flow control assembly, which is provided in plurality and corresponds one to one with the plurality of the mineral filter plates, and is used to adjust the effective area of ​​the corresponding mineral filter plates for raw water to pass through; and The controller is connected to the trace element concentration detector and the plurality of flow control components, and is configured to control the operation of the corresponding flow control components according to the difference between the mineral concentration detected by the trace element concentration detector and the standard mineral concentration.

[0013] Furthermore, a porous baffle is installed at the outlet end of the expanded flow channel, and the sampling end of the sampler is located between two opposite porous baffles.

[0014] Furthermore, the flow control component includes: A water baffle, which is lifted and arranged on the inner wall of the water barrier or the water inlet inner tank, and has a width greater than the corresponding width of the water outlet; The lifting drive member is installed on the outer wall of the water storage outer tank, the water baffle is installed on the output end of the lifting drive member, and the lifting drive member is connected to the controller.

[0015] The second aspect of the present application provides a method for producing a composite natural mineral water using the following technical solution: A method for producing composite natural mineral water, based on the above-mentioned composite natural mineral water production device, comprises the following steps: S1. Configure the mineral filter plates according to the type of minerals required for the raw mineral water. Install multiple mineral filter plates sequentially to the water inlet on the water inlet tank and the water outlet on several of the water barriers to form a multi-stage mineral addition system. S2. The raw water to be added with minerals is transported through the water inlet pipe to the water inlet inner tank. The raw water passes through the mineral filter plate on the water inlet inner tank, where the first mineral is added. The raw water then flows through the two sets of outlet flow channels, the acceleration flow channel, and the flared flow channel on the outside of the water inlet inner tank. The raw water is accelerated in the acceleration flow channel, and the raw water flow rate is reduced in the flared flow channel, inducing turbulent vortices. This significantly improves the uniformity of mineral dispersion in the raw water by enhancing shear force, inhibiting sedimentation, and promoting diffusion. S3. The raw water then passes through several mineral filter plates and is doped with other minerals. The raw water flows through the corresponding acceleration and expansion channels as it moves from the upstream to the downstream mineral filter plates, ensuring that each addition of minerals improves the uniformity of the newly added minerals in the raw water. S4. The mineral concentration in the raw water after adding minerals is detected by the dynamic adjustment mechanism, and the effective area of ​​the corresponding mineral filter plate for the raw water to pass through is adjusted to change the amount of minerals carried out when the raw water passes through the mineral filter plate, so that the mineral concentration in the raw water meets the standard mineral concentration requirements.

[0016] In summary, the beneficial technical effects of this application are: 1. By setting the cross section of the water inlet inner tank to be circular, the cross section of the water storage outer tank to be elliptical, the cross section center of the water storage outer tank, the cross section center of the water barrier and the cross section center of the water inlet inner tank are all collinear, and two water outlets close to the shortest straight-line distance to the central axis of the water inlet inner tank are arranged on two opposite sides of the central axis of the water inlet inner tank, so that two sets of symmetrically arranged water outlet flow channels, acceleration flow channels and expansion flow channels are formed between the two adjacent water outlets from the inside to the outside, so that the raw water can flow a longer distance in a limited space, which is more conducive to the minerals in the raw water. The dispersion in water can significantly improve space utilization; and relying on the characteristics of the mutually eccentrically connected ellipses, the width of the outlet flow channel is slightly larger than that of the acceleration flow channel, which facilitates the stable flow of raw water into the outlet flow channel after passing through the mineral filter plate; the acceleration flow channel has the smallest width, which can speed up the raw water to meet production requirements; the width of the flared flow channel gradually increases along the water flow direction from the connection part with the acceleration flow channel, and the increase in the flow channel can form eddies or turbulence in the flared flow channel, promoting the improvement of the uniformity of the dispersion of minerals in the raw water; 2. Different mineral filter plates are configured according to the types of minerals required by the raw mineral water. Multiple mineral filter plates are sequentially installed at the water outlet of the water inlet tank and the water outlets of several water barriers to form a multi-stage mineral addition system. Moreover, after each addition of minerals, the raw water needs to flow through the outlet flow channel, the acceleration flow channel, and the expansion flow channel in sequence, so that each added mineral can be more fully mixed and dispersed with the raw water, thereby improving the dispersion uniformity of these minerals in the raw water. This can reduce the stirring and mixing time or requirement for the raw water with added minerals in subsequent processes, and avoid impurities that may be introduced by traditional mechanical stirring. In particular, the previously added minerals can be mixed and dispersed multiple times, which is particularly suitable for the configuration of minerals with a low diffusion rate in the raw water. 3. By arranging multiple first and second spoilers in the flared flow channel, and utilizing one of two horizontal promotion and dispersion schemes, one-to-one and one staggered, and a combination of two vertical promotion and dispersion schemes, the turbulence of raw water flowing through the first and second spoilers can be intensified, thereby improving the uniformity of mineral dispersion in the raw water. Furthermore, the flow of raw water at different depths can be promoted, thereby improving the dispersion efficiency of minerals in raw water at different depths, and effectively improving the precipitation of minerals in the raw water. 4. After the raw water passes through the mineral filter plate and is added with minerals, it flows through the corresponding outlet flow channel, acceleration flow channel and expansion flow channel in sequence. The raw water evenly mixed with minerals then flows to the corresponding sampler, where it is sampled and the concentration of the added minerals in the raw water is detected by the trace element concentration detector. Based on the comparison with the standard concentration of the mineral, the shielding area of ​​the water baffle at the mineral filter plate corresponding to the mineral is controlled to change the total effective contact area between the mineral filter plate and the raw water, thereby changing the amount of mineral released and achieving the purpose of dynamically controlling the amount of mineral added to the water; 5. The setting of the porous baffle at the outlet end of the flared flow channel can, on the one hand, stabilize the turbulent flow of the raw water at the outlet end of the flared flow channel, so that the raw water flows more smoothly when approaching the sampling end of the sampler; on the other hand, it can also make the final dispersion and averaging of the minerals in the raw water to ensure the representativeness of the sampler each time it takes a sample.

[0019] The following will clearly and completely describe the technical solution of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0020] The present application embodiment discloses a composite natural mineral water production device. Figure 1 and Figure 2 It includes a water storage outer tank 1 and a water inlet inner tank 2. The water inlet inner tank 2 is provided with a water inlet pipe 21 located at its upper end, and the water storage outer tank 1 is provided with a water outlet pipe 11 located at its lower side. The water inlet inner tank 2 is arranged in the water storage outer tank 1.

[0021] Several water-blocking cylinders 3 and dynamic adjustment mechanisms are provided between the water inlet inner tank 2 and the water storage outer tank 1 .

[0022] Among them, several water risers 3 are sequentially sleeved on the outside of the water inlet inner tank 2, and their cross sections are elliptical and both upper and lower ends are fixedly connected to the water storage outer tank 1. In this embodiment, there are two water risers 3. The water inlet inner tank 2 is arranged on one side of the long axis end of the cross section of the innermost circle water riser 3, and the inner water riser 3 is located on one side of the long axis end of the cross section of the adjacent outer water riser 3. In addition, in order to further reduce the floor space occupied by the present application, the water inlet inner tank 2 is arranged to have a circular cross section, and the water storage outer tank 1 is arranged to have an elliptical cross section, and the center of the cross section of the water storage outer tank 1, the center of the cross section of the water riser 3, and the center of the cross section of the water inlet inner tank 2 are all collinear; at the same time, the outermost water riser 3 is located on one side of the long axis end of the cross section of the water storage outer tank 1, and the above-mentioned water outlet pipe 11 is arranged on the other side of the long axis end of the cross section of the water storage outer tank 1.

[0023] An outlet flow channel 41, an acceleration flow channel 42 and an expansion flow channel 43 that are connected in sequence are formed between the outer wall of the water inlet inner tank 2 and the inner wall on the long axis side of the innermost water barrier 3, between the inner and outer walls of the outer water barrier 3 and the inner water barrier 3 on the long axis side of the two, and between the inner wall of the water storage outer tank 1 and the outer wall on the long axis side of the outermost water barrier 3.

[0024] In addition, water outlets 51 are provided on one side of the water inlet inner tank 2 and the water barrier 3 close to the water outlet channel 41 located outside and adjacent thereto, and mineral filter plates 52 containing different minerals are installed at the multiple water outlets 51, such as mineral elements mainly composed of zinc, selenium, and strontium. Each mineral filter plate 52 corresponds to a mineral to be added, and the mineral filter plate 52 completely closes the corresponding water outlet 51; and in the specific setting, the mineral filter plate 52 can be an integrated porous plate sintered by minerals and ceramics, etc., or it can be tightly filled with spheres sintered by minerals and ceramics, etc., and the overall shape of the mineral filter plate 52 is an arc plate to adapt to the original complete shape of the water inlet inner tank 2 or the water barrier 3; in addition, it needs to be further explained that the central angle corresponding to the mineral filter plate 52 is not greater than 180°.

[0025] At the same time, two water inlets 51, which are closest to the shortest straight-line distance from the central axis of the water inlet inner tank 2, are located on opposite sides of the central axis of the water inlet inner tank 2. That is, from the inside to the outside, two adjacent water inlets 51 are connected by two sets of symmetrically arranged outlet channels 41, acceleration channels 42, and flared channels 43. Specifically, due to the elliptical shapes that are eccentrically connected to each other, the width of the outlet channel 41 is slightly larger than that of the acceleration channel 42, facilitating the stable flow of raw water into the outlet channel 41 after passing through the mineral filter plate 52. The acceleration channel 42 has the smallest width, which can accelerate the raw water to meet production requirements. The width of the flared channel 43 gradually increases along the water flow direction from its connection with the acceleration channel 42. The increase in the flow channel can be used to form vortices or turbulence in the flared channel 43.

[0026] The dynamic adjustment mechanism is used to detect the mineral concentration of the raw water after passing through the mineral filter plate 52 and adjust the effective area of ​​the corresponding mineral filter plate 52 for the raw water to pass through.

[0027] Therefore, refer to Figure 3When adding multiple minerals to the raw mineral water, first configure different mineral filter plates 52 according to the types of minerals required by the raw mineral water, and install multiple mineral filter plates 52 in sequence at the water outlet 51 on the water inlet inner tank 2 and the water outlets 51 on several water barriers 3 to form a multi-stage mineral addition system. Then, the raw water to be added with minerals is transported to the water inlet inner tank 2 through the water inlet pipe 21. After passing through the mineral filter plates 52 on the water inlet inner tank 2, the raw water carries out the minerals loaded thereon and is added with the first mineral. It then flows through the two groups of symmetrically arranged outlet flow channels 41, acceleration flow channels 42 and expansion flow channels 43 on the outside of the water inlet inner tank 2. The raw water is accelerated in the acceleration flow channel 42, and the raw water flow rate is reduced in the expansion flow channel 43, causing turbulent vortices. By enhancing shear force, inhibiting sedimentation and promoting diffusion, the dispersion uniformity of the first mineral added in the raw water can be significantly improved, effectively avoiding the occurrence of concentration differences after adding minerals to the raw water.

[0028] Next, the raw water with the first mineral added flows to the water outlet 51 of the innermost water barrier 3, and passes through the mineral filter plate 52 at the water outlet 51, where the second mineral is added. The raw water with the second mineral added flows in sequence through the two groups of symmetrically arranged outlet channels 41, acceleration channels 42, and expansion channels 43 on the outside of the innermost water barrier 3, which can further improve the dispersion uniformity of the second mineral in the raw water. Similarly, the raw water that passes through the mineral filter plate 52 on the outermost water barrier 3 is added with the third mineral, and circulates in the outlet channels 41, acceleration channels 42, and expansion channels 43 on the outside of the outermost water barrier 3 until it converges to the outlet pipe 11, at which point the dispersion uniformity of the third mineral in the raw water is also improved.

[0029] As a result, each mineral added by the production device of the present application can be more thoroughly mixed and dispersed with the raw water, thereby improving the uniformity of the dispersion of these minerals in the raw water, reducing the stirring and mixing time of the raw water to which the minerals have been added in subsequent processes, and avoiding impurities that may be introduced by traditional mechanical stirring. In particular, the previously added minerals can be mixed and dispersed multiple times, which is particularly suitable for the configuration of minerals with a low diffusion rate in the raw water; that is, minerals with a lower diffusion rate in the raw water are configured on the mineral filter plate 52 closer to the central axis of the water inlet inner tank 2, such as the aforementioned zinc element; minerals with a higher diffusion rate in the raw water are configured on the mineral filter plate 52 farther away from the central axis of the water inlet inner tank 2, such as the aforementioned strontium element.

[0030] Moreover, by means of the arrangement of two groups of water outlet channels 41, acceleration channels 42 and expansion channels 43 between two adjacent water outlets 51, the raw water can flow over a longer distance in a limited space, which is more conducive to the dispersion of minerals in the raw water and can significantly improve space utilization.

[0031] In addition, the production device of the present application also detects the mineral concentration in the raw water after adding minerals through the setting of a dynamic adjustment mechanism, and adjusts the effective area of ​​the corresponding mineral filter plate 52 for the raw water to pass through, so as to change the amount of minerals carried out when the raw water passes through the mineral filter plate 52, thereby realizing dynamic control of the amount of mineral added to the raw water, so that the mineral concentration in the raw water meets the standard mineral concentration requirements.

[0032] In order to further promote the uniformity of mineral dispersion in the raw water during the flow of the accelerating flow channel 42, refer to Figure 1 and Figure 2 , a plurality of first spoilers 61 extending along the raw water flow direction are installed on the outer wall of the water inlet inner tank 2 and the outer wall of the water barrier 3 corresponding to the adjacent expanded flow channel 43; A plurality of second spoilers 62 extending along the raw water flow direction are installed on the inner wall of the water storage outer tank 1 and the inner wall of the water barrier 3 at locations corresponding to the adjacent flared flow channels 43 .

[0033] Furthermore, considering that the raw water flow rate in the outer circle is greater than that in the inner circle when the raw water flows through the flared flow channel 43, in the same flared flow channel 43, the reduction in the flow rate of the flared flow channel 43 by the second spoiler 62 is greater than the reduction in the flow rate of the flared flow channel 43 by the first spoiler 61. That is, the length of the second spoiler 62 extending toward the middle of the flared flow channel 43 is greater than the length of the first spoiler 61 extending toward the middle of the flared flow channel 43. This ensures that the effect of the second spoiler 62 on the raw water flow rate in the outer circle is as close as possible to the effect of the first spoiler 61 on the raw water flow rate in the inner circle, thereby ensuring the raw water flow rate when flowing through the flared flow channel 43. In addition, the free ends of the first and second spoilers 61, 62 form an angle of 30° to 45° with the direction of the raw water flow, thereby controlling the water resistance within a moderate range.

[0034] Therefore, when the raw water accelerated by the accelerating flow channel 42 flows in the flared flow channel 43, it will be continuously disturbed by the multiple first spoilers 61 and the multiple second spoilers 62, which can form multiple eddies or turbulences, and can accelerate the collision between liquid molecules and minerals in the raw water to improve the mixing efficiency; thereby, on the premise of ensuring the flow rate of the raw water in the flared flow channel 43, the dispersion efficiency of the added minerals in the raw water can be further improved, effectively avoiding the occurrence of local concentration differences of minerals in the raw water.

[0035] More specifically, in one embodiment, in the same flared flow channel 43, multiple second spoilers 62 and multiple first spoilers 61 on the same horizontal plane can be arranged in a one-to-one correspondence or in a staggered arrangement. In this embodiment, the first spoilers 61 and the second spoilers 62 are chosen to be staggered. On the one hand, the flow path of the raw water in the flared flow channel 43 can be further lengthened; on the other hand, the turbulence of the raw water when flowing through the first spoiler 61 and the second spoiler 62 can be further intensified, thereby improving the uniformity of dispersion of minerals in the raw water.

[0036] Furthermore, in another embodiment, the plurality of first spoilers 61 and the plurality of second spoilers 62 can be arranged in an integrated manner or in a segmented manner along the axial direction of the water inlet inner tank 2. If the segmented arrangement is used, two adjacent groups of first spoilers 61 are staggered in the horizontal plane, and two adjacent groups of second spoilers 62 are staggered in the horizontal plane. That is, in the water expansion channel, raw water at different depths experiences different disturbances from the first spoilers 61 and the second spoilers 62 when flowing to a certain section of the water expansion channel. This arrangement can promote the flow of raw water at different depths, further improve the dispersion efficiency of minerals in raw water at different depths, and effectively improve the precipitation of minerals in the raw water.

[0037] It should be noted that one of the two horizontal promotion and dispersion schemes of one-to-one correspondence and staggered setting and one of the two vertical promotion and dispersion schemes of integrated setting and segmented setting can be combined with each other in pairs or one of the horizontal promotion and dispersion schemes and one of the vertical promotion and dispersion schemes can be selected. The specific combination depends on actual needs and is not limited here.

[0038] Moreover, in order to further promote the disturbing effect of the first spoiler 61 and the second spoiler 62 on the raw water, in other embodiments, a plurality of protrusions or a plurality of grooves can be further provided on the side of the first spoiler 61 and the second spoiler 62 close to the water flow direction, or a plurality of perforations can be opened through the free ends of the two spoilers to enhance the shearing effect of the first spoiler 61 and the second spoiler 62 on the raw water and promote the uniform dispersion of minerals in the raw water.

[0039] In addition, in order to ensure that the raw water flowing out of the mineral filter plate 52 at the water outlet 51 can flow smoothly into the acceleration channels on both sides, Figure 1 and Figure 2Diverter plates 7 are installed on the inner walls of both the water barrier 3 and the outer water storage tank 1, adjacent to the outlet channel 41. Diverter plates 7 have a pointed tip 71 in the middle of the side facing the water outlet 51. Extending from the tip 71 are curved diverter surfaces 72 extending toward the sides of the diverter plates 7. These curved diverter surfaces 72 direct the raw water toward the two acceleration channels 42 on either side. This minimizes velocity loss in the mineral-additive raw water at the outlet channel.

[0040] In order to realize the convenient control of the amount of minerals released from the mineral filter plate 52, refer to Figure 2 、 Figure 3 and Figure 4 , the above-mentioned dynamic adjustment mechanism includes: There are multiple samplers 8, which are arranged in a one-to-one correspondence with the multiple water outlets 51. The sampler 8 is arranged downstream of the water outlet 51 and between the two corresponding outlets of the flared flow channel 43; wherein, the sampling frequency of the sampler 8 can be controlled by a program to take timed samples, or it can take samples within a certain time after the flow control component works. The sampler 8 can be a commonly used peristaltic pump liquid sampler, and its sampling section extends between the two outlets of the flared flow channel 43.

[0041] The trace element concentration detector is used to detect the target mineral concentration in the sample water extracted by the sampler 8. For the detection of zinc and strontium, the trace element concentration detector can be an atomic absorption spectrometer (AAS) or an inductively coupled plasma emission spectrometer (ICP-OES), etc. For the detection of selenium, the trace element concentration detector can be a hydride generation-atomic fluorescence spectrometer (HG-AFS), etc.; the coordinated use of the sampler 8 and the trace element concentration detector is a conventional technical means in this field and will not be repeated here.

[0042] The flow control components are provided in multiple and corresponding to the multiple mineral filter plates 52, and are used to adjust the effective area of ​​the corresponding mineral filter plates 52 for raw water to pass through. The controller is connected to the trace element concentration detector and multiple flow control components, and is configured to control the operation of the corresponding flow control components according to the difference between the mineral concentration detected by the trace element concentration detector and the standard mineral concentration.

[0043] The flow control components include: A water baffle 91 is provided on the inner wall of the water riser 3 or the water inlet inner tank 2 for lifting, and its width is greater than the width of the corresponding water outlet 51. Guide rails 92 are fixedly connected to the inner walls of the water riser 3 and the water inlet inner tank 2 on both sides of the water outlet 51, and the water baffle 91 is stably raised and lowered by the two guide rails 92. The lifting drive component is installed on the outer wall of the water storage tank 1 (not shown in the figure), the water baffle 91 is installed at the output end of the lifting drive component, and the lifting drive component is connected to the controller; the lifting drive component can specifically be a cylinder, a hydraulic cylinder, an electric push rod, a linear motor, etc.

[0044] Furthermore, to prevent the turbulent flow of the raw water at the outlet of the flared flow channel 43 from affecting the representativeness of the sampling of the sampler 8, a porous baffle 63 is installed at the outlet of the flared flow channel 43, and the sampling end of the sampler 8 is located between two opposing porous baffles 63. The installation of the porous baffle 63 can, on the one hand, stabilize the turbulent flow of the raw water at the outlet of the flared flow channel 43, so that the raw water flows more smoothly as it approaches the sampling end of the sampler 8; on the other hand, it can also provide a final dispersion and averaging of the minerals in the raw water, ensuring the representativeness of each sampling by the sampler 8.

[0045] Therefore, after the raw water passes through the mineral filter plate 52 and is added with minerals, it circulates in turn through the corresponding outlet flow channel 41, the acceleration flow channel 42 and the expansion flow channel 43, which can significantly improve the dispersion uniformity of the minerals in the raw water. Then, the raw water with uniformly mixed minerals circulates to the corresponding sampler 8, and is sampled by the sampler 8 and the concentration of the added minerals in the raw water is detected by the trace element concentration detector. According to the comparison with the standard concentration of the mineral, the water baffle 91 at the mineral filter plate 52 corresponding to the mineral is controlled to block the mineral filter plate 52, so as to change the total effective contact area between the mineral filter plate 52 and the raw water, thereby changing the amount of mineral release, and achieving the purpose of dynamically controlling the amount of mineral added to the water. Specifically, for example, when the trace element concentration detector detects that the target mineral concentration in the raw water is lower than the standard concentration, the controller controls the corresponding lifting drive to drive the water baffle 91 to move upward to increase the effective contact area between the corresponding mineral filter plate 52 and the raw water. When the raw water input amount in the water inlet tank 2 is constant, the flow rate of the raw water flowing through the mineral filter plate 52 is reduced and the contact time with the mineral filter plate 52 is increased, so that the amount of minerals carried by the raw water when passing through the mineral filter plate 52 is increased, which can increase the amount of minerals added to the raw water; and vice versa.

[0046] The present application embodiment discloses a method for producing a composite natural mineral water, based on the above-mentioned composite natural mineral water production device, referring to Figure 1 、 Figure 2 and Figure 3 , which includes the following steps: S1. Configure different mineral filter plates 52 according to the type of minerals required for the mineral water source. Multiple mineral filter plates 52 are sequentially installed to the water inlet 51 on the inner tank 2 and the water outlet 51 on the water barrier 3 to form a multi-stage mineral addition system. S2. Raw water to be added with minerals is transported to the water inlet inner tank 2 via the water inlet pipe 21. The raw water passes through the mineral filter plate 52 on the water inlet inner tank 2, where the first mineral is added. The raw water then flows through the two sets of outlet flow channels 41, the acceleration flow channel 42, and the flared flow channel 43 on the outside of the water inlet inner tank 2. The raw water is accelerated in the acceleration flow channel 42, and its flow rate is reduced in the flared flow channel 43, inducing turbulent vortices. This significantly improves the uniformity of mineral dispersion in the raw water by enhancing shear force, inhibiting sedimentation, and promoting diffusion. S3. The raw water then passes through several mineral filter plates 52 in sequence and other minerals are added. The raw water flows through the corresponding acceleration flow channels 42 and expansion flow channels 43 in sequence as it flows from the upstream mineral filter plate 52 to the downstream mineral filter plate 52. Each addition of minerals promotes uniform dispersion of the newly added minerals in the raw water. S4. The mineral concentration in the raw water after adding minerals is detected by a dynamic adjustment mechanism, and the effective area of ​​the corresponding mineral filter plate 52 for the raw water to pass through is adjusted to change the amount of minerals carried out when the raw water passes through the mineral filter plate 52, so that the mineral concentration in the raw water meets the standard mineral concentration requirements.

[0047] The implementation principle of the production device of a composite natural mineral water in the embodiment of the present application is as follows: When adding multiple minerals to the raw mineral water, first, different mineral filter plates 52 are configured according to the types of minerals required by the raw mineral water, and multiple mineral filter plates 52 are sequentially installed at the water outlet 51 on the water inlet inner tank 2 and the water outlets 51 on several water barriers 3 to form a multi-stage mineral addition system. Then, the raw water to be added with minerals is transported to the water inlet inner tank 2 through the water inlet pipe 21. After passing through the mineral filter plates 52 on the water inlet inner tank 2, the raw water carries out the minerals loaded thereon and is added with the first mineral. It then flows through the two groups of symmetrically arranged outlet flow channels 41, acceleration flow channels 42 and expansion flow channels 43 on the outside of the water inlet inner tank 2. The raw water is accelerated in the acceleration flow channel 42, and the raw water flow rate is reduced in the expansion flow channel 43, causing turbulent vortices. By enhancing shear force, inhibiting sedimentation and promoting diffusion, the dispersion uniformity of the first mineral added in the raw water can be significantly improved, effectively avoiding the occurrence of concentration differences after the raw water is added with minerals.

[0048] Next, the raw water with the first mineral added flows to the water outlet 51 of the innermost water barrier 3, and passes through the mineral filter plate 52 at the water outlet 51, where the second mineral is added. The raw water with the second mineral added flows in sequence through the two groups of symmetrically arranged outlet channels 41, acceleration channels 42, and expansion channels 43 on the outside of the innermost water barrier 3, which can further improve the dispersion uniformity of the second mineral in the raw water. Similarly, the raw water that passes through the mineral filter plate 52 on the outermost water barrier 3 is added with the third mineral, and circulates in the outlet channels 41, acceleration channels 42, and expansion channels 43 on the outside of the outermost water barrier 3 until it converges to the outlet pipe 11, at which point the dispersion uniformity of the third mineral in the raw water is also improved.

[0049] As a result, each mineral added by the production device of this application can be more thoroughly mixed and dispersed with the raw water, thereby improving the uniformity of the dispersion of these minerals in the raw water. This can reduce the stirring and mixing time of the raw water with added minerals in subsequent processes and avoid the introduction of impurities that may be introduced by traditional mechanical stirring. In particular, the previously added minerals can be mixed and dispersed multiple times, which is particularly suitable for the configuration of minerals with slow diffusion rates in the raw water.

[0050] At the same time, after the raw water passes through the mineral filter plate 52 and is added with minerals, it circulates in turn through the corresponding outlet flow channel 41, the acceleration flow channel 42 and the expansion flow channel 43, which can significantly improve the dispersion uniformity of the minerals in the raw water. Then, the raw water with uniformly mixed minerals circulates to the corresponding sampler 8, and is sampled by the sampler 8 and the concentration of the added minerals in the raw water is detected by the trace element concentration detector. According to the comparison with the standard concentration of the mineral, the water baffle 91 at the mineral filter plate 52 corresponding to the mineral is controlled to block the mineral filter plate 52, so as to change the total effective contact area between the mineral filter plate 52 and the raw water, thereby changing the amount of mineral release, and achieving the purpose of dynamically controlling the amount of mineral added to the water.
