Abstract

The present invention relates to the technical field of drinking water production, and in particular to a mixing system for producing mixed gas water and a working method thereof, the system comprising a tank body, a gas-water collecting hood and a hydrogen dissolving device. In the working method of the system, the hydrogen dissolving device transports a portion of the mixed hydrogen water to a filling device after the process water and hydrogen are mixed, and another small portion of the mixed hydrogen water flows back to the tank body, and the process water is simultaneously input into the tank body, so that the process water and the hydrogen in the mixed hydrogen water are premixed in the tank body, and then the process water and hydrogen are collected into the hydrogen dissolving device through the gas-water collecting hood, forming a cyclic process. Since hydrogen moves upward after being dissolved in water, the gas-water collecting hood can expand the hydrogen collection area, increase the hydrogen concentration of the process water input into the hydrogen dissolving device after premixing, and ultimately help to improve the hydrogen concentration of the final produced mixed gas water, and the premixing of process water and hydrogen in the tank body is also conducive to improving the production efficiency of the mixed gas water.

Description

Technical Field

[0001] The invention relates to the technical field of drinking water production, in particular to a mixing system for producing aerated water and a working method thereof. Background Art

[0002] With the diversification of market consumption demand and the enhancement of health awareness, consumers are paying more and more attention to the health elements of products while considering simply quenching thirst and avoiding the heat. If the product can bring physical health after using it, it will be more popular. Therefore, in the future development, drinking water will gradually change from single quenching thirst and avoiding the heat to health, nutrition, beauty, etc. Mixed carbonated water beverages are expected to become the new favorite and mainstream development trend of the beverage market. The hydrogen ions of mixed carbonated water can neutralize the excess active oxygen in the body (H2+O=H2O) and combine into water, which is excreted from the body with urine to help cell metabolism. It is safe, green and environmentally friendly and has no toxic side effects on the human body. There are no clear contraindications and contraindication groups. The industrialization of mixed carbonated water is in line with the development trend of "nutrition, hygiene and convenience" in my country's food industry.

[0003] At present, the aerated water production equipment generally needs to mix the process water and hydrogen through a hydrogen dissolving device, but hydrogen is difficult to dissolve in water. Therefore, the actual hydrogen concentration of the aerated water produced by ordinary aerated water production equipment is relatively low. Summary of the invention

[0004] In view of the deficiencies raised in the above background technology, the present invention provides a mixing system for producing aerated water and a working method thereof.

[0005] The present invention adopts the following technical solution:

[0006] A mixing system for producing aerated water, characterized in that the system comprises:

[0007] A tank body, wherein a water inlet is provided at the bottom of the tank body, and the water inlet is used to input process water into the tank body; and a circulation port is also provided at the bottom of the tank body, and the circulation port is used to input hydrogen into the tank body;

[0008] An air-water collecting hood, wherein the air-water collecting hood has a conical opening, the opening faces downward, and a connecting pipe is connected to the air-water collecting hood, one end of the connecting pipe is in communication with the opening;

[0009] Wherein, the air-water collecting hood is arranged in the tank body, and the air-water collecting hood is located above the water inlet and the circulation port.

[0010] As an improvement of the above-mentioned mixing tank system, the system also includes a control unit, and a high liquid level sensing unit and a low liquid level sensing unit are arranged from top to bottom in the tank body above the gas and water collecting cover, and an electromagnetic valve is arranged at the water inlet, and the signals of the high liquid level sensing unit and the low liquid level sensing unit are both connected to the signal input end of the control unit, and the electromagnetic valve signal is connected to the signal output end of the control unit.

[0011] As an improvement of the above-mentioned mixing tank system, the system also includes a control unit, and a high liquid level sensing unit and a low liquid level sensing unit are arranged from top to bottom in the tank body above the gas and water collecting cover, and an electromagnetic valve is arranged at the water inlet, and the signals of the high liquid level sensing unit and the low liquid level sensing unit are both connected to the signal input end of the control unit, and the electromagnetic valve signal is connected to the signal output end of the control unit.

[0012] As an improvement to the above-mentioned mixing tank system, a water distributor is provided in the tank body, the water distributor is located below the air-water collecting hood, and the circulation pipe passes through the circulation port and is connected to the water distributor.

[0013] As an improvement to the above-mentioned mixing tank system, a drain port is further provided at the bottom of the tank body, and a valve is provided at the drain port.

[0014] As an improvement to the above-mentioned mixing tank system, a spray ball is further fixed to the top of the tank body, and the portion of the spray ball outside the tank body is connected to a water source.

[0015] As an improvement to the above-mentioned mixing tank system, a respirator is further provided at the top of the tank body. The respirator is arranged at the top of the tank body, and a sterilizing filter element is installed in the air hole of the respirator.

[0016] In the above-mentioned mixing tank system for producing mixed gas water, the tank body has a specified liquid level above the gas-water collecting hood, and the working method of the mixing tank system for producing mixed gas water is:

[0017] The water inlet of the tank body inputs process water into the tank body;

[0018] When the liquid level of the process water in the tank body is higher than the specified liquid level, the circulation port inputs the mixed hydrogen water into the tank body, so that the gas-water collecting cover collects the hydrogen and process water flowing upward in the tank body to the hydrogen dissolving device, and the hydrogen dissolving device outputs part of the mixed hydrogen water to the circulation port. The hydrogen dissolving device is a device that mixes process water and hydrogen to form mixed hydrogen water.

[0019] As an improvement of the above method, two process water level height positions, a high liquid level and a low liquid level, are arranged in the tank body from top to bottom, and the designated liquid level is the low liquid level; when the process water level in the tank body is higher than the high liquid level, the water inlet stops inputting process water; when the process water level in the tank body is lower than the low liquid level, the water inlet starts inputting process water.

Since hydrogen will move upward after being dissolved in water, the gas-water collecting cover can expand the hydrogen collection area and increase the amount of hydrogen collected, reduce the loss of hydrogen in the process water, and increase the hydrogen concentration of the process water input into the hydrogen dissolving device after premixing. Compared with the method of directly inputting process water into the hydrogen dissolving device in the traditional production process, it is beneficial to increase the hydrogen concentration of the final produced mixed gas water. In addition, the process water and hydrogen are premixed in the tank body, which is equivalent to mixing the process water with hydrogen in advance before entering the hydrogen dissolving device, so it is beneficial to improve the production efficiency of mixed gas water. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 It is a structural schematic diagram of the present invention. DETAILED DESCRIPTION

[0022] The specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0023] A mixing system for producing mixed gas water comprises a tank body 1, a hydrogen dissolving device 4 and a control unit. The tank body 1 is fixed on a fixing bracket 11 to form a vertically fixed structure, and the bottom of the tank body 1 is a cone structure with a large top and a small bottom.

[0024] A water inlet 12 is provided at the bottom of the tank body 1, and the water inlet 12 is connected to the source of process water through a pipeline. A solenoid valve is also provided at the water inlet 12, and the solenoid valve signal is connected to the control unit. The opening and closing of the solenoid valve is controlled by the control unit so that process water can be input into the tank body 1 from the bottom of the tank body 1 through the water inlet. The process water is water that can meet the needs of production, that is, water that meets the hygiene standards, and can specifically be filtered tap water. A drain port 13 is also provided at the bottom of the tank body 1, and a valve is installed at the drain port 13. When the production is completed, the valve can be opened to discharge the residual water in the tank body 1 from the bottom. Preferably, a three-way valve can be fixed at the bottom of the tank body 1, and the port on the side of the three-way valve is the water inlet 12, and the port on the bottom of the three-way valve is the drain port 13.

[0025] An air-water collecting hood 2 is provided above the water inlet 12 in the tank body 1. The air-water collecting hood 2 has a conical opening 201, and the opening 201 faces downward, which is equivalent to the air-water collecting hood 2 being a trumpet-shaped structure with a small top and a large bottom. A connecting pipe 22 is also connected to the air-water collecting hood 2, one end of which is in communication with the opening 21, and the other end of the connecting pipe 22 passes through the outside of the tank body 1 and is connected to the hydrogen dissolving device.

[0026] The hydrogen dissolving device 4 can be a gas-liquid mixing pump, and the hydrogen dissolving device 4 has an air inlet 41, a liquid inlet 42 and an output port 43. The air inlet 41 is connected to the hydrogen generator 5 through a pipeline, so that the hydrogen produced by the hydrogen generator 5 can be input into the hydrogen dissolving device 4. The liquid inlet 42 is connected to the end of the connecting pipe 22 away from the gas-water collecting hood 2, so that the process water and hydrogen collected by the gas-water collecting hood 2 can be directly input into the hydrogen dissolving device 4 and mixed with the hydrogen produced by the hydrogen generator 5. The output port 43 is used to output the mixed hydrogen water formed by the mixture of hydrogen and process water, and the output port 43 can be divided into two pipelines by connecting a three-way pipe, one of which is connected to the filling equipment 8, and the other is connected to the circulation port 14 below the tank body 1 through a circulation pipe 44, and the position where the circulation pipe 44 is connected to the tank body 1 is located below the gas-water collecting hood 2. In addition, a water distributor 45 is provided in the tank body, and the water distributor 45 is located below the gas-water collecting cover. The circulation pipe is connected to the water distributor 45 in the tank body 1. The structure of the water distributor 45 can be used to prevent hydrogen micro-nanometers contained in the process water from impacting each other and destroying its own structure.

[0027] Furthermore, a proportional distributor may be provided at the output port 43 to adjust the flow of the mixed hydrogen water output to the filling device 8 and the mixed hydrogen water output to the tank body 1 in the two-way pipeline of the output port 43, for example, a ratio of 10:1, so that most of the mixed hydrogen water is transported to the emulsification pump to obtain mixed gas water and finally transported to the filling device 8, while a small part of the mixed hydrogen water is circulated back to the tank body 1 through the circulation pipe 44. After this small part of the mixed hydrogen water is circulated back to the tank body 1 through the circulation pipe 44, the mixed hydrogen water is mixed with the process water input from the water inlet 12, thereby increasing the hydrogen concentration in the process water input to the tank body 1, and playing the role of premixing the process water and hydrogen, which is conducive to improving the efficiency of the subsequent mixing of the process water and hydrogen in the hydrogen dissolving device 4.

[0028] In the above structure, since hydrogen moves upward after being dissolved in water, the trumpet-shaped structure of the gas-water collecting cover 2 can expand the collection area, reduce the loss of hydrogen in the process water, and make the hydrogen in the tank body 1 flow back to the hydrogen dissolving device 4 through the connecting pipe 22 after being collected, thereby increasing the hydrogen solubility in the process water input into the hydrogen dissolving device 4. In addition, in the above structure, the process water is input from the bottom of the tank body 1 and collected by the gas-water collecting cover 2 in the middle of the tank body 1. This process is equivalent to prolonging the mixing time of the process water and hydrogen, which is beneficial to increasing the hydrogen concentration in the mixed process water.

[0029] The tank body 1 is also provided with a respirator 7 and a spray ball 6. Since the process water entering and exiting the tank body 1 will cause changes in the internal space of the tank body 1, the respirator 7 is arranged on the top of the tank body 1 to connect the inside and outside of the tank body 1, thereby balancing the pressure inside and outside the tank body 1. Furthermore, a sterilization filter is installed in the air hole of the respirator 7 to prevent bacteria in the air from entering the tank body 1 and causing water pollution. The spray ball 6 is fixed to the top of the tank body 1, and the part of the spray ball 6 outside the tank body 1 is connected to the water source through a pipeline. When cleaning is required, clean water can be pumped into each of the spray balls 6 by a water pump, so that the clean water is sprayed from the spray ball 6 to the inner wall of the tank body 1, thereby achieving the purpose of cleaning the tank body 1. After cleaning is completed, the valve at the drain port 13 can also be opened to discharge all the cleaned water.

[0030] In addition, two height positions, a high liquid level and a low liquid level, are arranged from top to bottom in the tank body 1 above the gas-water collecting hood 2, and a high liquid level sensing unit 32 is provided at the high liquid level position, and a low liquid level sensing unit 31 is provided at the low liquid level position. The signals of the high liquid level sensing unit 32 and the low liquid level sensing unit 31 are both connected to the signal input end of the control unit, and the solenoid valve at the water inlet 12 and the hydrogen dissolving device 4 are both connected to the signal output end of the control unit. Among them, the high liquid level sensing unit 32 and the low liquid level sensing unit 31 are both liquid level sensors, and the control unit is a PLC controller, which can control the orderly operation of the mixed gas and water mixing tank system of the present invention by writing a program in the control unit. Specifically, the working method of the mixed gas and water mixing tank system of the invention is as follows:

[0031] S1: The control unit controls the solenoid valve at the water inlet 12 to open, so that the water inlet 12 starts to input process water into the tank body 1;

[0032] S2: When the liquid level of the process water input into the tank body 1 is higher than the low liquid level sensing unit, the low liquid level sensing unit 31 is triggered, and the low liquid level sensing unit 31 sends a triggering signal to the control unit, and the control unit controls the hydrogen dissolving device 4 to start running, so that the hydrogen dissolving device 4 extracts the process water and hydrogen collected by the gas-water collecting cover 2 and transports them to the hydrogen dissolving device 4 through the connecting pipe 22 to mix with the hydrogen, and outputs mixed hydrogen water, so that the circulating pipe 44 can input the mixed hydrogen water into the tank body 1;

[0033] S3: When the liquid level of the process water in the tank body 1 is higher than the high liquid level sensing unit 32, the high liquid level sensing unit 32 is triggered, and the high liquid level sensing unit 32 sends a triggering signal to the control unit, and the control unit controls the solenoid valve at the water inlet 12 to close, so that the water inlet 12 stops inputting process water. At this time, the hydrogen dissolving device 4 continues to operate to extract the process water and hydrogen in the tank body 1;

[0034] S4: When the process water in the tank body 1 gradually decreases as the hydrogen dissolving device 4 extracts, the process water level in the tank body 1 decreases. After the level is lower than the low level sensing unit 31, the low level sensing unit 31 is triggered again. The low level sensing unit 31 sends a triggering signal to the control unit. The control unit controls the solenoid valve at the water inlet 12 to open according to step S1, and the water inlet 12 continues to input process water, and the cycle continues.

[0035] It can be seen from the above working method that the present invention circulates a small portion of the mixed hydrogen water after mixing in the hydrogen dissolving device 4 back into the tank body 1, and the tank body 1 simultaneously inputs process water, so that the process water and the mixed hydrogen water are premixed in the tank body 1, and then the process water and hydrogen are collected into the hydrogen dissolving device 4 through the gas-water collecting cover 2. Since hydrogen will move upward after being dissolved in water, the gas-water collecting cover 2 can expand the hydrogen collection area, increase the amount of hydrogen collected, reduce the loss of hydrogen in the process water, and increase the hydrogen concentration of the process water input to the hydrogen dissolving device 4 after premixing. Compared with the method of directly inputting process water into the hydrogen dissolving device 4 in the traditional production process, it is beneficial to increase the hydrogen concentration of the final produced mixed gas water. In addition, the process water and hydrogen are premixed in the tank body 1, which is equivalent to mixing the process water with hydrogen in advance before entering the hydrogen dissolving device, so it is beneficial to improve the production efficiency of mixed gas water.

[0036] The above is only a specific implementation of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
