Description

Technical Field

[0001] This application relates to the technical field of mineral water production, and in particular to a method and apparatus for producing compound natural mineral water. Background Technology

[0002] Natural mineral water is uncontaminated underground mineral water that flows 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, and water temperature remain relatively stable within natural fluctuations. When processing this type of natural mineral water into drinking water, it needs to be treated according to the mineral content and limits specified in national standards. In particular, when a certain mineral is lacking or its content does not meet national standards, minerals need to be added to the raw water.

[0003] Chinese patent application CN202011456365.7 discloses a method and apparatus for producing composite natural mineral water. The apparatus includes a dedicated metasilicic acid filter media device comprising three layers: a zinc filter layer, a selenium filter layer, and a strontium filter layer. The zinc filter layer is positioned above the selenium filter layer, with the selenium filter layer in the middle. Source water sequentially passes through the zinc filter layer, the selenium filter layer, and the strontium filter layer before flowing out. This apparatus has a simple structure and can preserve trace elements in the water, thus improving the quality of the mineral water.

[0004] The aforementioned technologies have the following drawbacks: While combining pure minerals into filter media to form a stable composite material offers good durability and biocompatibility, allowing raw water to flow through the mineral-containing media and carry out the desired minerals with precise control over the release rate and proportion, these filter media are typically installed as a single unit. This makes it difficult to dynamically control the release of minerals when the water flow rate on the production line remains constant, thus mitigating the instability of mineral content in the raw water. Furthermore, different minerals diffuse at different rates in the raw water, leading to uneven mineral distribution due to variations in localized dissolution concentrations as the raw water passes through the filter media. Summary of the Invention

[0005] To address the challenges of dynamically controlling the amount of minerals added to raw water and the resulting differences in mineral concentration, this application provides a method and apparatus for producing composite natural mineral water.

[0006] The first aspect of this application provides a production apparatus for compound natural mineral water, which adopts the following technical solution:

[0007] A production apparatus for composite natural mineral water includes an outer water storage tank and an inner water inlet tank. The inner water inlet tank is equipped with an inlet pipe, and the outer water storage tank is equipped with an outlet pipe. The inner water inlet tank is disposed within the outer water storage tank, and a connection is provided between the inner water inlet tank and the outer water storage tank.

[0008] Several water-proof cylinders are provided, each with an elliptical cross-section and both ends fixed to the outer water storage tank. The inner water inlet tank is located on one side of the long axis end of the cross-section of the innermost water-proof cylinder. The inner water-proof cylinder is located on one side of the long axis end of the cross-section of the adjacent outer water-proof cylinder. A sequentially connected water outlet channel, an acceleration channel, and a flared channel are formed between the outer wall of the inner water inlet tank and the inner wall of the inner water inlet tank, between the inner and outer walls of the outer water inlet tank and the inner wall of the inner water inlet tank on the long axis side, and between the inner wall of the outer water storage tank and the outer wall of the outermost water inlet tank on the long axis side.

[0009] Water inlets are located on the side of the inlet tank and the baffle cylinder near the outlet channel, which is situated on their outer side. Mineral filter plates containing different minerals are installed at each of the multiple water inlets. Two water inlets with the shortest straight-line distance to the central axis of the inlet tank are positioned on opposite sides of the central axis.

[0010] A dynamic adjustment mechanism is used to detect the mineral concentration of the raw water after it passes through the mineral filter plate and adjust the effective area of ​​the corresponding mineral filter plate that allows the raw water to pass through.

[0011] Furthermore, multiple first baffles extending along the direction of the original water flow are installed on the outer wall of the water inlet tank and the outer wall of the water-proof cylinder at the locations adjacent to the flared flow channel.

[0012] Multiple second baffles extending along the direction of the original water flow are installed on the inner walls of the outer water storage tank and the inner walls of the baffle cylinder corresponding to the adjacent flared flow channels.

[0013] Furthermore, in the same flared flow channel, the reduction in flow rate of the flared flow channel by the second spoiler is greater than the reduction in flow rate of the flared flow channel by the first spoiler.

[0014] Furthermore, within the same flared flow channel, multiple second spoilers and multiple first spoilers on the same horizontal plane are arranged in an alternating manner.

[0015] Furthermore, multiple sets of the first and second baffles are arranged in sections along the axial direction of the water inlet tank, with adjacent sets of the first baffles staggered on the horizontal plane and adjacent sets of the second baffles staggered on the horizontal plane.

[0016] Furthermore, a diversion plate is installed on the inner wall of the water-proof cylinder and the inner wall of the outer water storage tank at the location corresponding to the adjacent water outlet channel. The diversion plate has a pointed tip in the middle of the side facing the adjacent water outlet, and the pointed tip extends into a diversion curved surface towards the side of the diversion plate. The diversion curved surface is used to guide the raw water to the two acceleration channels on both sides.

[0017] Furthermore, the dynamic adjustment mechanism includes:

[0018] A sampler is provided in multiple locations, each corresponding to one of the multiple water inlets. The sampler is located downstream of the water inlet and between the two corresponding flared flow channel outlets.

[0019] A trace element concentration detector is used to detect the concentration of target minerals in water samples extracted by a sampler.

[0020] A flow control component, comprising multiple mineral filter plates, each corresponding to one of the aforementioned mineral filter plates, is used to adjust the effective surface area of ​​the corresponding mineral filter plate through which raw water can pass; and

[0021] The controller, connected to the trace element concentration detector and multiple flow control components, is configured to control the operation of the corresponding flow control components based on the difference between the mineral concentration detected by the trace element concentration detector and the standard mineral concentration.

[0022] Furthermore, a porous baffle is installed at the outlet end of the flared flow channel, and the sample inlet end of the sampler is located between two opposing porous baffles.

[0023] Furthermore, the flow control component includes:

[0024] A baffle plate is raised and lowered on the inner wall of the water-separating cylinder or the water inlet tank, and its width is greater than the width of the corresponding water outlet.

[0025] A lifting drive unit is installed on the outer wall of the water storage tank, and a baffle plate is installed at the output end of the lifting drive unit. The lifting drive unit is connected to the controller.

[0026] The second aspect of this application provides a method for producing compound natural mineral water using the following technical solution:

[0027] A method for producing compound natural mineral water, based on the aforementioned apparatus for producing compound natural mineral water, includes the following steps:

[0028] S1. Configure different mineral filter plates according to the types of minerals required by the raw mineral water, and install multiple mineral filter plates sequentially at the water outlet on the inner water tank and the water outlet on several water separators to form a multi-stage mineral addition system.

[0029] S2. The raw water to be added with minerals is transported to the inner tank through the inlet pipe. After passing through the mineral filter plate on the inner tank, the raw water is added with the first mineral. Then it flows through the two sets of outlet channels, acceleration channels and flared channels on the outside of the inner tank. It is accelerated in the acceleration channels and the raw water velocity is reduced in the flared channels to induce turbulent vortices. By enhancing shear force, inhibiting sedimentation and promoting diffusion, the uniformity of mineral dispersion in the raw water can be significantly improved.

[0030] S3. Subsequently, the raw water passes through several mineral filter plates in sequence and other minerals are added. As the raw water flows from the upstream mineral filter plate to the downstream mineral filter plate, it flows through the corresponding acceleration channel and flared channel in sequence, so that each time minerals are added, the newly added minerals can be evenly dispersed in the raw water.

[0031] 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 that the raw water can pass through is adjusted to change the amount of minerals carried out by the raw water when passing through the mineral filter plate, so that the mineral concentration in the raw water meets the standard mineral concentration requirements.

[0032] In summary, the beneficial technical effects of this application are as follows:

[0033] 1. By designing the inner inlet tank with a circular cross-section and the outer storage tank with an elliptical cross-section, and ensuring that the centers of the outer storage tank's cross-section, the baffle's cross-section, and the inner inlet tank's cross-section are all collinear, and by placing two water inlets closest to the central axis of the inner inlet tank on opposite sides of the central axis, two sets of symmetrically arranged outlet channels, acceleration channels, and flared channels are formed between adjacent water inlets from the inside out. This allows the raw water to circulate a longer distance within a limited space, which is more conducive to the mineralization of the raw water. The dispersion in the water can significantly improve space utilization; moreover, relying on the eccentric interlocking elliptical characteristics, the width of the outlet channel is slightly larger than that of the acceleration channel, which facilitates the stable flow of raw water through the mineral filter plate into the outlet channel; the acceleration channel has the smallest width, which can accelerate the flow of raw water to meet production requirements; the width of the flared channel gradually increases along the water flow direction from its connection with the acceleration channel, which can form eddies or turbulence in the flared channel by means of the channel increase, promoting the uniformity of mineral dispersion in the raw water;

[0034] 2. By configuring different mineral filter plates according to the types of minerals required for the raw mineral water, and sequentially installing multiple mineral filter plates at the inlet of the inner water tank and at the inlets of several water-separating cylinders, a multi-stage mineral addition system can be formed. Moreover, after each addition of minerals, the raw water needs to flow through the outlet channel, acceleration channel, and flared channel in sequence, so that each added mineral can be thoroughly mixed and dispersed with the raw water, thereby improving the uniformity of these minerals in the raw water. This can reduce the stirring and mixing time or requirements of the raw water with added minerals in subsequent processes and avoid impurities that may be introduced by traditional mechanical stirring. In particular, the minerals added earlier can be mixed and dispersed multiple times, which is especially suitable for the formulation of minerals with low diffusion rates in the raw water.

[0035] 3. By setting multiple first and second baffles in the flared flow channel, and by combining one of two horizontal dispersion promotion schemes (one-to-one and staggered) and two vertical dispersion promotion schemes (integrated and segmented), not only can the turbulence of raw water flowing through the first and second baffles be intensified, improving the uniformity of mineral dispersion in the raw water; it can also promote the flow between raw water at different depths, further enhancing the dispersion efficiency of minerals in the raw water at different depths, and effectively improving the precipitation phenomenon of minerals in the raw water;

[0036] 4. After the raw water passes through the mineral filter plate and minerals are added, it flows sequentially through the corresponding outlet channel, acceleration channel and flared channel. Then, the raw water, which is uniformly mixed with minerals, flows to the corresponding sampler, where it is sampled and the concentration of the added mineral in the raw water is detected by the trace element concentration detector. Based on the comparison with the standard concentration of the mineral, the area of ​​the baffle plate 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 release amount of minerals and achieving the purpose of dynamically controlling the amount of minerals added to the water.

[0037] 5. The perforated baffle at the outlet end of the flared channel serves two purposes: firstly, it stabilizes the turbulent flow of raw water at the outlet end of the flared channel, making the flow of raw water more stable when it approaches the sampler's inlet end; secondly, it also performs final dispersion and averaging of minerals in the raw water, ensuring the representativeness of each sample taken by the sampler.

[0052] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0053] This application discloses a production apparatus for composite natural mineral water. (Refer to...) Figure 1 and Figure 2 It includes an outer water storage tank 1 and an inner water inlet tank 2. The inner water inlet tank 2 is provided with an inlet pipe 21 located at its upper end, and the outer water storage tank 1 is provided with an outlet pipe 11 located at its lower side. The inner water inlet tank 2 is located inside the outer water storage tank 1.

[0054] Several water-proof cylinders 3 and a dynamic adjustment mechanism are installed between the inner water inlet tank 2 and the outer water storage tank 1.

[0055] In this embodiment, several water-separating cylinders 3 are sequentially fitted around the inner water inlet tank 2. Each water-separating cylinder has an elliptical cross-section and is fixed to the outer water storage tank 1 at both ends. In this embodiment, two water-separating cylinders 3 are provided. The inner water inlet tank 2 is located on one side of the major axis of the cross-section of the innermost water-separating cylinder 3, and the innermost water-separating cylinder 3 is located on one side of the major axis of the cross-section of the adjacent outermost water-separating cylinder 3. Furthermore, to further reduce the footprint of this application, the inner water inlet tank 2 is configured with a circular cross-section, and the outer water storage tank 1 is configured with an elliptical cross-section. The center of the cross-section of the outer water storage tank 1, the center of the cross-section of the water-separating cylinder 3, and the center of the cross-section of the inner water inlet tank 2 are all collinear. Simultaneously, the outermost water-separating cylinder 3 is located on one side of the major axis of the cross-section of the outer water storage tank 1, and the aforementioned water outlet pipe 11 is located on the other side of the major axis of the cross-section of the outer water storage tank 1.

[0056] A sequentially connected water outlet channel 41, an acceleration channel 42, and a flared channel 43 are formed between the outer wall of the inner water inlet tank 2 and the inner wall of the innermost water baffle 3 on one side of their long axis, between the outer water baffle 3 and the inner water baffle 3 on one side of their long axis, and between the inner wall of the outer water storage tank 1 and the outer wall of the outermost water baffle 3 on one side of their long axis.

[0057] Furthermore, water inlets 51 are provided on the side of the inner water tank 2 and the water separator 3 near the outer side and adjacent to the water outlet channel 41. Each water inlet 51 is equipped with a mineral filter plate 52 containing different minerals, such as zinc, selenium, and strontium. Each mineral filter plate 52 corresponds to a mineral to be added, and the mineral filter plate 52 completely seals the corresponding water inlet 51. In specific settings, the mineral filter plate 52 can be an integral porous plate made of minerals and ceramics, or it can be made of spheres made of minerals and ceramics that are tightly filled. The overall shape of the mineral filter plate 52 is arc-shaped to match the original complete shape of the inner water tank 2 or the water separator 3. In addition, it should be further noted that the central angle of the mineral filter plate 52 is no greater than 180°.

[0058] Meanwhile, two water inlets 51 with the shortest straight-line distance to the central axis of the inner water tank 2 are located on opposite sides of the central axis of the inner water tank 2. That is, two adjacent water inlets 51 from the inside to the outside are connected by two sets of symmetrically arranged outlet channels 41, acceleration channels 42 and flared channels 43. Among them, relying on the eccentrically connected elliptical characteristics, the width of the outlet channel 41 is slightly larger than the width of the acceleration channel 42, which facilitates the stable flow of raw water through the mineral filter plate 52 into the outlet channel 41; the acceleration channel 42 has the smallest width, which can accelerate the flow of 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, which can form vortices or turbulence in the flared channel 43 by means of the increase in the width of the channel.

[0059] 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 mineral filter plate 52 that the raw water can pass through.

[0060] Therefore, referring to Figure 3 When adding multiple minerals to raw mineral water, different mineral filter plates 52 are first configured according to the types of minerals required by the raw mineral water. Multiple mineral filter plates 52 are then installed sequentially at the inlet 51 on the inner water tank 2 and at the inlet 51 on several water separators 3, forming a multi-stage mineral addition system. Then, the raw water to be mineralized is transported to the inner water tank 2 through the inlet pipe 21. After passing through the mineral filter plates 52 on the inner water tank 2, the raw water carries out the minerals loaded on them and is added with the first type of mineral. Subsequently, it flows through two sets of symmetrically arranged outlet channels 41, acceleration channels 42, and flared channels 43 on the outside of the inner water tank 2. The raw water is accelerated in the acceleration channels 42 and its flow velocity is reduced and turbulent vortices are generated in the flared channels 43. By enhancing shear force, inhibiting sedimentation, and promoting diffusion, the dispersion uniformity of the first type of mineral in the raw water can be significantly improved, effectively avoiding concentration differences after adding minerals to the raw water.

[0061] Next, the raw water with the first mineral added flows to the inlet 51 of the innermost water-separating cylinder 3 and passes through the mineral filter plate 52 at the inlet 51, where a second mineral is added. The raw water with the second mineral added then flows sequentially through two sets of symmetrically arranged outlet channels 41, acceleration channels 42, and flared channels 43 on the outer side of the innermost water-separating cylinder 3, which further improves the uniformity of the dispersion of the second mineral in the raw water. Similarly, the raw water passing through the mineral filter plate 52 on the outermost water-separating cylinder 3 is added with a third mineral and flows through the outlet channels 41, acceleration channels 42, and flared channels 43 on the outermost water-separating cylinder 3 until it converges at the outlet pipe 11, where the uniformity of the dispersion of the third mineral in the raw water is also improved.

[0062] This allows each mineral added through the production apparatus of this application to be more thoroughly mixed and dispersed with the raw water, thereby improving the uniformity of dispersion of these minerals in the raw water. This reduces the stirring and mixing time of the raw water with added minerals in subsequent processes and avoids impurities that may be introduced by traditional mechanical stirring. In particular, the minerals added earlier can be mixed and dispersed multiple times, which is especially suitable for minerals with low diffusion rates in the raw water. That is, minerals with lower diffusion rates in the raw water are placed on the mineral filter plate 52 closer to the central axis of the inner water tank 2, such as the zinc element mentioned above; while minerals with higher diffusion rates in the raw water are placed on the mineral filter plate 52 further away from the central axis of the inner water tank 2, such as the strontium element mentioned above.

[0063] Moreover, by setting up two sets of water outlet channels 41, acceleration channels 42 and flaring channels 43 between two adjacent water outlets 51, the raw water can circulate 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.

[0064] In addition, the production device of this application, through the setting of a dynamic adjustment mechanism, also detects the mineral concentration in the raw water after the addition of minerals, and adjusts the effective area of ​​the corresponding mineral filter plate 52 that the raw water can 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 minerals added to the raw water, so that the mineral concentration in the raw water meets the standard mineral concentration requirements.

[0065] To further promote the uniformity of mineral dispersion in the raw water during its flow in the acceleration channel 42, reference is made to... Figure 1 and Figure 2 Multiple first baffles 61 extending along the direction of the original water flow are installed on the outer wall of the water inlet tank 2 and the outer wall of the water baffle cylinder 3 at the locations corresponding to the adjacent flared flow channels 43.

[0066] Multiple second baffles 62 extending along the direction of the original water flow are installed on the inner wall of the outer water tank 1 and the inner wall of the water-proof cylinder 3 at the locations corresponding to the adjacent flared flow channels 43.

[0067] Furthermore, considering that the flow rate of raw water in the outer ring is greater than that in the inner ring when the raw water flows in the flared channel 43, the reduction in flow rate of the second baffle 62 in the same flared channel 43 is greater than that of the first baffle 61. That is, the length of the second baffle 62 extending into the middle of the flared channel 43 is greater than the length of the first baffle 61 extending into the middle of the flared channel 43. This is to ensure that the influence of the second baffle 62 on the raw water flow rate in the outer ring is as close as possible to the influence of the first baffle 61 on the raw water flow rate in the inner ring, thus ensuring the flow rate of raw water when it flows in the flared channel 43. In addition, the free ends of the first baffle 61 and the second baffle 62 form an angle of 30° to 45° with the direction of raw water flow, which can control the resistance to water within a moderate range.

[0068] Therefore, when the raw water accelerated by the acceleration channel 42 flows in the flared channel 43, it will be continuously turbulent by multiple first baffles 61 and multiple second baffles 62, which can form multiple eddies or turbulences, accelerate the collision between liquid molecules and minerals in the raw water, and improve the mixing efficiency. Thus, while ensuring the flow rate of the raw water in the flared 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.

[0069] More specifically, in one embodiment, in the same flared flow channel 43, the multiple second baffles 62 and multiple first baffles 61 on the same horizontal plane can be arranged in a one-to-one correspondence or in an alternating manner. In this embodiment, the first baffles 61 and the second baffles 62 are arranged in an alternating manner. On the one hand, this can further lengthen the flow path of the raw water in the flared flow channel 43; on the other hand, it can further intensify the turbulence phenomenon when the raw water flows through the first baffles 61 and the second baffles 62, thereby improving the uniformity of mineral dispersion in the raw water.

[0070] Furthermore, in another embodiment, the plurality of first baffles 61 and the plurality of second baffles 62 along the axial direction of the inlet tank 2 can be integrally arranged or arranged in multiple segments. If arranged in segments, adjacent sets of first baffles 61 are staggered on the horizontal plane, and adjacent sets of second baffles 62 are staggered on the horizontal plane. That is, in the expanded water channel, the disturbance phenomenon of raw water at different depths when flowing to a certain section of the expanded water channel by the first baffles 61 and the second baffles 62 is different. This arrangement can promote the flow between raw water at different depths, and further promote the dispersion efficiency of minerals in raw water at different depths; and can also effectively improve the precipitation phenomenon of minerals in raw water.

[0071] It should be noted that one of the two horizontal dispersion promotion schemes of one-to-one correspondence setting and staggered setting, and one of the two vertical dispersion promotion schemes of integrated setting and segmented setting, can be combined in pairs or one of the horizontal dispersion promotion schemes and one of the vertical dispersion promotion schemes can be chosen at will. The specific combination depends on the actual needs and is not restricted here.

[0072] Furthermore, to further enhance the disturbance effect of the first baffle plate 61 and the second baffle plate 62 on the raw water, in other embodiments, multiple protrusions or grooves can be provided on the side of the first baffle plate 61 and the second baffle plate 62 near the water flow direction, or multiple perforations can be opened through the free ends of the two baffle plates to improve the shearing effect of the first baffle plate 61 and the second baffle plate 62 on the raw water and promote the uniform dispersion of minerals in the raw water.

[0073] In addition, to ensure that the raw water flowing out of the mineral filter plate 52 at the inlet 51 can flow smoothly into the acceleration channels on both sides, refer to Figure 1 and Figure 2Diverter plates 7 are installed on the inner wall of the water-insulating cylinder 3 and the inner wall of the outer water storage tank 1 at locations corresponding to the adjacent outlet channels 41. The diverter plate 7 has a pointed tip 71 in the middle of the side facing the adjacent water outlet 51, and the pointed tip 71 extends into a diverting curved surface 72 on the side of the diverter plate 7. The diverting curved surface 72 is used to guide the raw water to the two acceleration channels 42 on both sides. This can minimize the loss of flow velocity of the raw water at the outlet channel after the addition of minerals.

[0074] In order to achieve convenient control over the release of minerals in mineral filter plate 52, refer to Figure 2 , Figure 3 and Figure 4 The aforementioned dynamic adjustment mechanism includes:

[0075] Samplers 8 are provided in multiple locations, each corresponding to one of the multiple water inlets 51. The samplers 8 are located downstream of the water inlets 51 and between the outlets of the two flared flow channels 43. The sampling frequency of the samplers 8 can be controlled by a program to sample at regular intervals, or it can sample within a certain period of time after the flow control component is working. The samplers 8 can be commonly used peristaltic pump-type liquid samplers, and their sampling section extends between the outlets of the two flared flow channels 43.

[0076] The trace element concentration detector is used to detect the concentration of target minerals 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 optical 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 combined use of the sampler 8 and the trace element concentration detector is a conventional technique in this field and will not be described in detail here.

[0077] The flow control component comprises multiple mineral filter plates 52, each corresponding to a specific plate, and is used to adjust the effective surface area of ​​the corresponding mineral filter plate 52 through which raw water can pass.

[0078] The controller, connected to a trace element concentration detector and multiple flow control components, is configured to control the operation of the corresponding flow control components based on the difference between the mineral concentration detected by the trace element concentration detector and the standard mineral concentration.

[0079] The flow control components include:

[0080] The baffle plate 91 is raised and lowered on the inner wall of the water-proof cylinder 3 or the water inlet tank 2, and its width is greater than the width of the corresponding water outlet 51; wherein, the water-proof cylinder 3 and the water inlet tank 2 are both fixedly connected to the inner walls on both sides of their water outlet 51, and the baffle plate 91 is raised and lowered stably through the two guide rails 92.

[0081] The lifting drive is installed on the outer wall of the water storage tank 1 (not shown in the figure), and the baffle plate 91 is installed at the output end of the lifting drive. The lifting drive is connected to the controller. The lifting drive can be a cylinder, hydraulic cylinder, electric push rod, linear motor, etc.

[0082] Furthermore, to prevent the turbulence of the raw water at the outlet of the flared channel 43 from affecting the representativeness of the sample taken by the sampler 8, a porous baffle 63 is installed at the outlet of the flared channel 43, with the inlet of the sampler 8 located between two opposing porous baffles 63. The porous baffle 63 serves two purposes: firstly, it stabilizes the turbulence of the raw water at the outlet of the flared channel 43, making the flow of the raw water more stable as it approaches the inlet of the sampler 8; secondly, it also performs final dispersion and averaging of the minerals in the raw water, ensuring the representativeness of each sample taken by the sampler 8.

[0083] Therefore, when raw water passes through the mineral filter plate 52 and minerals are added, it flows sequentially through the corresponding outlet channel 41, acceleration channel 42, and flared channel 43, which can significantly improve the uniformity of mineral dispersion in the raw water. Subsequently, the raw water with uniformly mixed minerals flows to the corresponding sampler 8, where it is sampled and the concentration of the added mineral in the raw water is detected by the trace element concentration detector. Based on the comparison with the standard concentration of the mineral, the blocking area of ​​the baffle plate 91 at the mineral filter plate 52 corresponding to the mineral is controlled to change the total effective contact area between the mineral filter plate 52 and the raw water, thereby changing the amount of mineral released and achieving the purpose of dynamically controlling the amount of minerals added to the water. Specifically, for example, when the trace element concentration detector detects that the concentration of the target mineral in the raw water is lower than the standard concentration, the controller controls the corresponding lifting drive to move the baffle 91 upward, so as to increase the effective contact area between the corresponding mineral filter plate 52 and the raw water. When the raw water input in the inlet tank 2 is constant, the flow rate of the raw water through the mineral filter plate 52 decreases and the contact time with the mineral filter plate 52 increases, so that the amount of minerals carried by the raw water when passing through the mineral filter plate 52 increases, which can increase the amount of minerals added to the raw water; and vice versa.

[0084] This application discloses a method for producing composite natural mineral water, based on the aforementioned apparatus for producing composite natural mineral water, with reference to... Figure 1 , Figure 2 and Figure 3 It includes the following steps:

[0085] S1. 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 to the water outlet 51 on the inner water tank 2 and the water outlet 51 on several water separators 3 to form a multi-stage mineral addition system.

[0086] S2. The raw water to be added with minerals is transported to the inner water tank 2 through the inlet pipe 21. After passing through the mineral filter plate 52 on the inner water tank 2, the raw water is added with the first mineral. Then it flows through the two sets of outlet channels 41, acceleration channel 42 and flared channel 43 on the outside of the inner water tank 2. It is accelerated in the acceleration channel 42 and the raw water flow velocity is reduced in the flared channel 43 to induce turbulent vortex. By enhancing shear force, inhibiting sedimentation and promoting diffusion, the dispersion uniformity of minerals in the raw water can be significantly improved.

[0087] S3. Subsequently, the raw water passes through several mineral filter plates 52 in sequence and other minerals are added. As the raw water flows from the upstream mineral filter plate 52 to the downstream mineral filter plate 52, it flows through the corresponding acceleration channel 42 and the flared channel 43 in sequence, so that the newly added minerals can be evenly dispersed in the raw water after each addition of minerals.

[0088] 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 52 that the raw water can 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.

[0089] The implementation principle of the composite natural mineral water production device in this application embodiment is as follows:

[0090] When adding multiple minerals to raw mineral water, different mineral filter plates 52 are first configured according to the types of minerals required for the raw mineral water. Multiple mineral filter plates 52 are then installed sequentially at the inlet 51 on the inner water tank 2 and at the inlet 51 on several water separators 3, forming a multi-stage mineral addition system. Then, the raw water to be mineralized is transported to the inner water tank 2 through the inlet pipe 21. After passing through the mineral filter plates 52 on the inner water tank 2, the raw water carries out the minerals loaded on them and the first type of mineral is added. Subsequently, it flows through two sets of symmetrically arranged outlet channels 41, acceleration channels 42, and flared channels 43 on the outside of the inner water tank 2. The raw water is accelerated in the acceleration channels 42 and its flow velocity is reduced and turbulent vortices are generated in the flared channels 43. By enhancing shear force, inhibiting sedimentation, and promoting diffusion, the dispersion uniformity of the first type of mineral in the raw water can be significantly improved, effectively avoiding concentration differences after adding minerals to the raw water.

[0091] Next, the raw water with the first mineral added flows to the inlet 51 of the innermost water-separating cylinder 3 and passes through the mineral filter plate 52 at the inlet 51, where a second mineral is added. The raw water with the second mineral added then flows sequentially through two sets of symmetrically arranged outlet channels 41, acceleration channels 42, and flared channels 43 on the outer side of the innermost water-separating cylinder 3, which further improves the uniformity of the dispersion of the second mineral in the raw water. Similarly, the raw water passing through the mineral filter plate 52 on the outermost water-separating cylinder 3 is added with a third mineral and flows through the outlet channels 41, acceleration channels 42, and flared channels 43 on the outermost water-separating cylinder 3 until it converges at the outlet pipe 11, where the uniformity of the dispersion of the third mineral in the raw water is also improved.

[0092] This allows each mineral added through the production apparatus of this application to be more thoroughly mixed and dispersed with the raw water, thereby improving the uniformity of dispersion of these minerals in the raw water. This reduces the stirring and mixing time of the raw water with added minerals in subsequent processes and avoids impurities that may be introduced by traditional mechanical stirring. In particular, the minerals added earlier can be mixed and dispersed multiple times, which is especially suitable for the preparation of minerals with low diffusion rates in the raw water.

[0093] Meanwhile, after the raw water passes through the mineral filter plate 52 and is infused with minerals, it flows sequentially through the corresponding outlet channel 41, acceleration channel 42, and flared channel 43. This significantly improves the uniformity of mineral dispersion in the raw water. The raw water, now uniformly mixed with minerals, then flows to the corresponding sampler 8, where it is sampled and the concentration of the added minerals in the raw water is detected by a trace element concentration detector. Based on the comparison with the standard concentration of the mineral, the area of ​​the baffle plate 91 at the mineral filter plate 52 corresponding to the mineral is controlled to change the total effective contact area between the mineral filter plate 52 and the raw water, thereby changing the amount of minerals released and achieving the purpose of dynamically controlling the amount of minerals added to the water.
