Description

Technical Field

[0001] This utility model relates to the field of water treatment device technology, specifically to a drinking water mineralization device for precise control of silicon content. Background Technology

[0002] Silicon typically exists in water as soluble silicates and is considered one of the essential trace elements for maintaining human health, playing a positive role in bone growth and cardiovascular health. While natural mineral water contains silicon, its content is fixed and cannot meet the personalized needs of different populations or specific health requirements. Therefore, the demand for mineralization treatment of drinking water, especially for silicon supplementation, is increasing.

[0003] The most common method of mineralizing drinking water on the market is to add a mineralizing filter cartridge at the back end of the water purifier (such as a reverse osmosis water purifier). These filter cartridges are usually filled with natural mineral materials such as maifan stone. This passive dissolution method means that users cannot know the actual amount of minerals they are supplementing, and cannot adjust the content of specific elements (silicon) according to their own needs or doctor's advice, which may cause problems of insufficient or excessive supplementation. Utility Model Content

[0004] To overcome the problems in the background technology, this utility model provides a drinking water mineralization device for precise control of silicon content, solving the problem of unstable and uncontrollable silicon content in existing mineralization devices, and realizing adjustable and precise control of silicon content in drinking water.

[0005] A drinking water mineralization device for precise regulation of silicon content includes an inlet pipe, a mineralization branch pipe, a regulating branch pipe, a silicon filter element unit, a three-way pipe, a control valve, a mineralization outlet pipe, a mixing pipe, an outlet pipe, and a control unit. The inlet port of the inlet pipe is connected to the drinking water source, and the outlet port of the inlet pipe is connected to the inlet ports of the mineralization branch pipe and the regulating branch pipe. The outlet port of the mineralization branch pipe is connected to the inlet port of the silicon filter element unit, and at least two silicon filter elements connected in series are connected in series in the mineralization branch pipe. The silicon filter elements are connected to each other through a three-way pipe. The branch pipe of the three-way pipe is connected to the inlet port of the mineralization outlet pipe. The control valve is installed on the outlet port of each three-way pipe. The outlet port of the mineralized water outlet pipe is connected to the inlet port of the mixing pipe, and the outlet port of the regulating branch pipe is also connected to the inlet port of the mixing pipe. Flow regulating devices are installed at the two inlet ends of the mixing pipe, and the outlet port of the mixing pipe is connected to the outlet pipe. The control unit includes a PLC controller, a silicon detection unit, and a flow detection unit. The silicon detection unit and the flow detection unit are connected to the PLC controller, and the PLC controller is connected to the control valve.

[0006] Furthermore, the silicon detection unit includes a first silicon detection unit, a second silicon detection unit, and a third silicon detection unit. The first silicon detection unit is installed on the inlet pipe, the second silicon detection unit is installed on the mineralized outlet pipe, and the third silicon detection unit is installed on the outlet pipe.

[0007] Furthermore, the flow detection unit includes a first flow detection unit and a second flow detection unit. The first flow detection unit is installed at the outlet end of the mineralized water outlet pipe, and the second flow detection unit is installed at the outlet end of the regulating branch pipe.

[0008] Furthermore, the control valve is a solenoid valve.

[0009] Furthermore, the silicon filter element unit is a filter tube filled with mineral filter media or artificial silicon-containing materials capable of releasing soluble silicates.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model achieves coarse adjustment of the mineralization level (silicon content) range by using a series segmented filter cartridge combined with an optional outlet valve, and then fine adjustment of the bypass mixing ratio, so as to accurately and stably control the silicon content of the effluent within the target range set by the user; it can automatically adjust the mineralization level and mixing ratio according to the different silicon content of the raw water (measured by the first silicon detection unit) and the different needs of the user for the target silicon content, which is highly adaptable. Users can set different target silicon contents according to their health needs or preferences to meet personalized drinking water needs.

[0011] 2. The closed-loop feedback control of this utility model can compensate for the impact of factors such as filter cartridge consumption, water temperature changes, and flow fluctuations on the silica dissolution rate, ensuring the long-term stability of the silica content in the effluent.

Detailed Implementation

[0015] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0016] See Figure 1 This utility model proposes a drinking water mineralization device for precise control of silicon content, including an inlet pipe 1, a mineralization branch pipe 2, a regulating branch pipe 3, a silicon filter element unit 4, a three-way pipe 5, a control valve 6, a mineralization outlet pipe 7, a mixing pipe 8, an outlet pipe 9, and a control unit. The inlet of the main inlet pipe 1 is connected to the drinking water source to be treated (water that has undergone pre-purification treatment). Preferably, a first silicon detection unit 11 is installed on the inlet pipe 1 to monitor the silicon content of the raw water in real time. See Figure 1 The inlet pipe 1 is divided into two branches after the first silicon detection unit 11 via a diversion structure (Y-type connector): a mineralization branch pipe 2 and a regulating branch pipe 3. Several silicon filter cartridge units 4 (four in the example) are connected in series within the mineralization branch pipe 2. Each silicon filter cartridge unit 4 is filled with mineral filter media or artificial silicon-containing materials that can release soluble silicates into the water. The inlet of the first silicon filter cartridge unit 4 is connected to the mineralization branch pipe 2, and the outlet of the first silicon filter cartridge unit 4 is connected to the inlet of a three-way pipe 5. One outlet of this three-way pipe 5 is connected to the inlet of the second silicon filter cartridge unit 4, and the other outlet (branch pipe outlet) is connected to a control valve. 6 is connected to the mineralized water outlet pipe 7. Similarly, the outlet of the second silicon filter unit 4 is also connected to the inlet of the next tee pipe 5. One outlet of the tee pipe 5 is connected to the inlet of the third silicon filter unit 4, and the other outlet (branch outlet) is connected to the mineralized water outlet pipe 7 through another control valve 6, and so on until the last (nth) silicon filter unit 4, whose outlet is connected directly or through a control valve 6 to the mineralized water outlet pipe 7. This invention provides more flexible control by setting control valves 6 on both outlet paths of each tee pipe. The control valves 6 are preferably solenoid valves to facilitate their opening and closing by electrical signals.

[0017] See Figure 1 The mineralized water outlet pipe 7 collects the mineralized water flowing out of the branch pipe outlets of each tee pipe 5. On the mineralized water outlet pipe 7, before the mixing pipe 8, a second silicon detection unit 12 and a first flow detection unit 14 are preferably set to detect the silicon content and flow rate of the collected mineralized water, respectively. The outlet of the mineralized water outlet pipe 7 is connected to an inlet of the mixing pipe 8. See Figure 1 The regulating branch pipe 3 is directly connected to the other inlet of the water inlet pipe 1 and the mixing pipe 8 to transport unmineralized raw water (or purified water). On the regulating branch pipe 3, before the mixing pipe 8, a second flow detection unit 15 is preferably set to detect the flow rate of the bypass water.

[0018] See Figure 1The mixing pipe 8 is a cavity or pipe section used to fully mix mineralized water and bypass water. Flow adjustment devices 81 are installed at the two inlet ends of the mixing pipe. The outlet of the mixing pipe 8 is connected to the final outlet pipe 9. Preferably, a third silicon detection unit 13 is installed on the outlet pipe 9 to detect the silicon content of the final mixed output water.

[0019] This utility model also includes a control unit comprising a PLC controller, which is connected to the first silicon detection unit 11, the second silicon detection unit 12 and the third silicon detection unit 13, the first flow detection unit 14, the second flow detection unit 15 and all the control valves 6.

[0020] Work process: The user sets the desired target silicon content range through the interactive interface connected to the control unit (such as a dedicated application on the user's mobile phone connected via Bluetooth module). The controller first reads the raw water silicon content of the first silicon detection unit 11. The controller determines how many interconnected silicon filter units 4 need to be passed through sequentially to reach or slightly exceed the target silicon content based on the target silicon content, the raw water silicon content, and the preset mineralization capacity model of each silicon filter unit 4 (or feedback from the second silicon detection unit 12). For example, if the target content is high, the controller can open the passage to allow the water to pass through all or most of the filter units sequentially; if the target content is low, the controller may only open the passage to allow the water to pass through the first or first few filter units before introducing it into the mineralization outlet pipe through the corresponding control valve 6 and the three-way pipe 5. 7; Specifically, the controller selects the water flow path by precisely controlling the switching combination of the solenoid valve 6 installed on the outlet path of the three-way pipe 5, that is, controlling the number of series filter cartridges through which the water flows; for example, to make the water flow only through the first section, the valve leading to the mineralized water outlet pipe 7 after the first section is opened, while the valve leading to the second section is closed; to make the water flow through the first two sections, the valve leading to the mineralized water outlet pipe 7 after the first section is closed, the valve leading to the second section is opened, then the valve leading to the mineralized water outlet pipe 7 after the second section is opened, and the valve leading to the third section is closed, and so on; After being mineralized by a selected number of filter cartridges, the water flows into the mineralized water outlet pipe 7. Its silicon content is measured by the second silicon detection unit 12, and its flow rate is measured by the first flow rate detection unit 14. At the same time, the unmineralized water flows through the regulating branch pipe 3, and its flow rate is measured by the second flow rate detection unit 15. The controller calculates the required mixing ratio of mineralized water and bypass water based on the silicon content of the mineralized water measured by the second silicon detection unit 12, the silicon content of the raw water measured by the first silicon detection unit 11, and the target silicon content. Then, based on the real-time flow readings of the first flow detection unit 14 and the second flow detection unit 15, the controller precisely adjusts the flow ratio of the two water flows through the flow regulating device 81 (a proportional control valve installed on the mineralization branch and the regulating branch) so that they reach the target silicon content after mixing in the mixing pipe 8. The third silicon detection unit 13 is used to monitor the silicon content of the final effluent in real time and feed the results back to the controller. The controller can further fine-tune the state of the control valve 6 (adjusting the mineralization level) or the mixing ratio based on this feedback signal, forming a closed-loop control, thereby maintaining the silicon content of the effluent within the target range more accurately and stably. This utility model, through the combination of the above-mentioned series segmented selectable outlet and bypass mixing, supplemented by multi-point sensing and closed-loop control structure, can achieve precise regulation of the silicon content in drinking water.

[0021] To more clearly illustrate the control logic of this utility model, a specific embodiment of flow mixing control is provided: Assuming the user sets the target silica content (St) in the effluent to be 20 mg / L: 1. Initial State and Detection: After the controller starts, it first reads the data from each sensor. Assume that at this point: The first silicon detection unit 11 measured the silicon content of the raw water to be S1 = 5 mg / L; Based on the target St=20mg / L and the raw water S1=5mg / L, the controller initially determined that a moderate degree of mineralization was required, and thus controlled the solenoid valve 6 to allow the water to flow through the first two silicon filter units 4. The second silicon detection unit 12 measured the silicon content of the water (mineralized water) after two stages of mineralization to be S2=50mg / L; The third silicon detection unit 13 measured the silicon content S3 at the outlet of the current mixing pipe 8 (i.e., the total outlet 9) to be 25 mg / L, which is higher than the target value. The first flow detection unit 14 measured the mineralized water flow rate F1 = 1 L / min; The second flow detection unit 15 measured the bypass water (regulating branch pipe 3) flow rate F2 = 1L / min.

[0022] 2. Target mixing ratio calculation: The controller calculates the ideal flow ratio of mineralized water (S2) to bypass water (S1) required to achieve the target silicon content St based on the mass balance principle: Rtarget = F1target / F2target. The formula is as follows: St=(F1target*S2+F2target*S1) / (F1target+F2target) 20=(F1target*50+F2target*5) / (F1target+F2target) Let Rtarget = F1target / F2target. Divide both sides by F2target to find the ideal flow ratio Rtarget = 15 / 30 = 0.5, which means the flow rate of the mineralized water should be 0.5 times the flow rate of the bypass water.

[0023] 3. Current Status Assessment: The controller compares the current actual flow rate with the following parameters: Ractual = F1 / F2 = 1L / min / 1L / min = 1 and target flow rate Rtarget = 0.5; Ractual>Rtarget indicates that the current proportion of mineralized water is too high (or the proportion of bypass water is too low), which is consistent with the situation where the actual effluent silicon content S3=25mg / L measured by the third silicon detection unit 13 is higher than the target value St=20mg / L.

[0024] 4. Control adjustment command issuance: To make the actual ratio Ractual approach the target ratio Rtarget (0.5), the PLC controller adjusts the flow of one or two of the two channels. This can be achieved by controlling the flow regulating device 81 (electronic proportional valve) installed on the mineralization branch 7 or the regulating branch 3. (1) Reduce the flow rate of mineralized water F1: The controller issues a command to close the proportional valve on the mineralized branch 7, so that F1 decreases until F1 / F2≈0.5.

[0025] (2) Increase the bypass water flow rate F2: The controller issues a command to open the proportional valve on the regulating branch 3 to increase F2 until F1 / F2≈0.5.

[0026] (3) Adjust F1 and F2 at the same time: slightly close the valve of F1 and slightly open the valve of F2 to reach the target ratio more quickly and possibly keep the total outflow rate roughly unchanged.

[0027] 5. Closed-loop feedback and continuous adjustment: After the controller executes the adjustment command, it continuously monitors the silica content S3 of the effluent from the third silica detection unit 13 and the readings F1 and F2 of the second flow sensor 14 and the second flow sensor 15. If S3 still deviates from St, or F1 / F2 deviates from Rtarget, the controller will further fine-tune the flow regulation device using the PID control algorithm according to the magnitude and direction of the deviation, until S3 stabilizes near the target value St (20mg / L±1mg / L).

[0028] 6. Adjustment of mineralization stages: If, during the process of adjusting the flow rate ratio, it is found that even if the bypass water flow rate F2 is adjusted to the maximum (or the mineralized water flow rate F1 is adjusted to the minimum), the silica content S3 of the effluent is still higher than the target value St, this indicates that the mineralized water concentration S2 produced by the currently selected mineralization stage (2 stages) is too high. At this time, the controller re-evaluates and controls the solenoid valve 6 to reduce the number of filter stages through which the water flows (only the first stage flows through), and then repeats the above mixing ratio calculation and adjustment process. Conversely, if even if the bypass water flow rate F2 is zero, the silica content S3 of the effluent is still lower than St, the controller will increase the number of filter stages through which the water flows.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
