Description

Technical Field

[0001] The utility model belongs to the technical field of water vapor mixing, and in particular relates to a gas and liquid mixing pressurized conveying device. Background Art

[0002] Mixing liquid and gas is a common technology in industrial production. For example, in the production of soda, sparkling wine, hydrogen-rich water, etc., gas and liquid are mixed. Water-gas mixing usually involves separately transporting liquid and gas to a water-gas mixing device for mixing.

[0003] For example, a tea bar machine is disclosed in the Chinese document with publication number CN220141387U, wherein the water circuit module includes a water circuit board and a first water pump and a second water pump connected to the water circuit board respectively, wherein the first water pump is used to pump water from the bottled water into the refrigeration module, and the second water pump is used to pump water from the bottled water into the electric kettle. The first water pump is used to pump water from the bottled water into the refrigeration module so that the refrigeration module refrigerates the normal temperature direct drinking water in the bottled water to produce ice water; an air pump and an exhaust valve are arranged in the second chamber, wherein the air pump is used to transport gas into the water-gas mixing device to squeeze out the ice water in the water-gas mixing device, and the exhaust valve is used to control the water-gas mixing device to exhaust air into the bottled water. When the air pump blows air into the water-gas mixing device, the air pressure of the water-gas mixing device increases, thereby squeezing out the ice bubble water. When the exhaust valve is opened, the water-gas mixing device can discharge excess air into the bottled water and release the pressure, thereby ensuring that the ice water and carbon dioxide gas can smoothly enter the water-gas mixing device. It can be seen that in the above patent documents, water and gas are separately mixed in the mixing device. This will lead to insufficient mixing of water and gas, resulting in a low gas content in the water, especially for gases that are difficult to dissolve in water, which will further cause the gas content in the water to be low.

[0004] In order to overcome the defects of the above-mentioned patent scheme, a water-gas secondary mixing output device is disclosed in the Chinese patent document with publication number CN117101455A. The water flows through the water valve and flows to the booster pump. When the water flow detection device detects the water flow passing through, the booster pump can be started by the control system. Under the action of the booster pump, the water flow and the hydrogen overflowing from the water flow can be pressurized and then transported to the water-gas mixing device for secondary mixing. The overflowed hydrogen is re-mixed with water molecules and water molecules to increase the hydrogen content in the water again.

[0005] However, during the operation of the booster pump, since the water flow contains a large amount of gas, there is a large amount of gas in the self-priming process of the booster pump, and the self-priming force is reduced. During the process of reducing the self-priming force, the booster pump will stop working. Utility Model Content

[0006] The utility model aims to provide a gas and liquid mixed pressurized conveying device to solve the problem that when water and gas are pressurized and mixed and conveyed together, the pressure pump will stop because the self-priming force is reduced.

[0007] To achieve the above-mentioned purpose, the embodiment of the utility model provides a gas and liquid mixed pressurized delivery device, characterized in that it includes a first self-priming pump, a second self-priming pump, a connecting piece and a gas supply device;

[0008] The connecting piece includes three pipe joints, the output port of the first self-priming pump is connected to the connecting piece pipeline, and the input port of the first self-priming pump is connected to the liquid supply system;

[0009] The input port of the second self-priming pump is connected to the connecting piece pipeline, and the output port of the second self-priming pump is connected to the mixing device pipeline;

[0010] The output end of the gas supply device is connected to the connecting piece pipeline, and the gas supply device is used to input constant pressure gas into the connecting piece;

[0011] After the first self-priming pump stops running, the second self-priming pump automatically stops running.

[0012] Furthermore, a one-way valve is provided at the output port of the air supply device, and the driving force for opening the one-way valve is equal to or greater than the air pressure output by the air supply device, so that when the second self-priming pump stops running, the one-way valve is closed.

[0013] Furthermore, a pressure sensor is connected to one end of the output port of the air supply device closer to the one-way valve. The pressure sensor is used to detect the air pressure at the output port of the air supply device. The air pressure at the output port of the air supply device is maintained constant, and the control system controls the air supply device to close.

[0014] Furthermore, the self-priming force of the second self-priming pump is greater than the self-priming force of the first self-priming pump.

[0015] Furthermore, the connecting part includes a shell and an air pipe; a partition is provided in the shell, and the partition forms two independent first cavities and second cavities in the shell; a first pipe joint and a second pipe joint are extended at both ends of the first cavity, the first self-priming pump is connected to the first pipe joint, and the second self-priming pump is connected to the second pipe joint; the air pipe is arranged in the second cavity, and one end of the air pipe passes through the shell to be connected to the air supply device, and the other end passes through the partition to be connected to the first cavity.

[0016] Furthermore, the trachea is a multi-segment U-shaped structure.

[0017] Furthermore, a rectangular hole is provided on the partition, and a flat air nozzle located in the rectangular hole is provided at the end of the air pipe.

[0018] Furthermore, the first cavity is a circular cavity, and a screw is also provided in the first cavity, and the screw and the inner wall of the first cavity form a spiral flow channel.

[0019] Furthermore, the connecting piece is an electronic three-way valve; and the air supply device is a constant pressure air supply device.

[0020] The above one or more technical solutions in the gas and liquid mixed pressurized delivery device provided by the embodiment of the utility model have at least the following technical effects:

[0021] 1. When mixing water, the gas and liquid mixing and pressurizing conveying device can start the first self-priming pump, the second self-priming pump and the air supply device at the same time; the first self-priming pump conveys the liquid into the connecting piece, and the air supply device conveys the gas into the connecting piece; the second self-priming pump pressurizes and outputs the liquid and gas. Since the first self-priming pump continuously supplies pressurized liquid to the second self-priming pump, the pressure can be increased, and the liquid pressure can be increased. Even if there is a large amount of gas in the liquid entering the second self-priming pump, the self-priming pressure will not be reduced, thereby ensuring that the second self-priming pump can operate normally and stably; thereby ensuring the normal mixing of gas and liquid.

[0022] 2. In the gas and liquid mixed pressurized delivery device, when the first self-priming pump fails or the first self-priming pump is in a state of empty suction, the self-priming force decreases rapidly, and the first self-priming pump automatically stops working, and cannot provide pressurized liquid to the second self-priming pump, causing the second self-priming pump to be in a state of empty suction. Therefore, the second self-priming pump automatically stops, avoiding the problem of the mixing device running all the time.

[0023] A hydrogen-rich water machine comprises a gas and liquid mixing pressurized conveying device and an electrolyzer, wherein the hydrogen output port of the electrolyzer is connected to the gas supply device; when the first self-priming pump stops running, the electrolyzer stops running.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0033] In one embodiment of the gas and liquid mixed pressurized delivery device of the utility model, please refer to Figure 1-2The gas and liquid mixing and pressurizing conveying device is used for pressurizing and mixing gas and liquid to provide the gas content in the liquid. Specifically, the gas and liquid mixing and pressurizing conveying device includes a first self-priming pump 100, a second self-priming pump 200, a connecting piece 300 and a gas supply device 400.

[0034] The connecting piece 300 includes three pipe joints. The output port of the first self-priming pump 100 is connected to the connecting piece 300 through a pipeline, and the input port of the first self-priming pump 100 is connected to the liquid supply system.

[0035] The input port of the second self-priming pump 200 is connected to the pipeline of the connecting piece 300, and the output port of the second self-priming pump 200 is connected to the pipeline of the mixing device.

[0036] The output end of the air supply device 400 is connected to the connecting piece 300 through a pipeline; the first self-priming pump 100 stops running, and then the second self-priming pump 200 automatically stops running.

[0037] When mixing water, the gas and liquid mixing and pressurizing conveying device can start the first self-priming pump 100, the second self-priming pump 200 and the air supply device 400 at the same time; the first self-priming pump 100 conveys the liquid into the connecting piece 300, and the air supply device 400 conveys the gas into the connecting piece 300. The second self-priming pump 200 pressurizes the liquid and gas mixture and outputs it to the mixing device. Since the first self-priming pump 100 continuously provides pressurized liquid to the second self-priming pump 200, the pressure can be increased, and the liquid pressure can be increased. Even if there is a large amount of gas in the liquid entering the second self-priming pump 200, the self-priming pressure will not be reduced, thereby ensuring that the second self-priming pump 200 can operate normally and stably; thereby ensuring the normal mixing of gas and liquid. In addition, in the present gas and liquid mixed pressurized delivery device, when the first self-priming pump 100 fails or the first self-priming pump 200 is in an empty suction state, the self-priming force decreases rapidly, and the first self-priming pump 100 will automatically stop working, and it will be unable to provide pressurized liquid to the second self-priming pump 200, causing the second self-priming pump 200 to also be in an empty suction state. Therefore, the second self-priming pump 200 automatically stops, avoiding the problem of the mixing device running all the time.

[0038] Further, refer to Figure 3 The output port of the air supply device 400 is also provided with a one-way valve 410, and the driving force for opening the one-way valve 410 is equal to or greater than the air pressure output by the air supply device 400, so that when the second self-priming pump 200 stops running, the one-way valve 410 can close automatically. In this embodiment, when the second self-priming pump 200 stops working, the one-way valve 410 can be closed to stop the air supply. When the second self-priming pump 200 is working, under the action of the suction force of the second self-priming pump 200 and the pressure of the air supply device 400, the one-way valve 410 can be opened to achieve normal air supply.

[0039] Further, refer to Figure 3 , the output port of the air supply device 400 is closer to the one-way valve 410, and the pressure sensor 420 is used to detect the air pressure of the output port of the air supply device 400. The air pressure at the output port of the air supply device 400 is maintained constant, and the control system controls the air supply device 400 to close. In this embodiment, it is possible to detect whether the second self-priming pump 200 is stopped by the pressure sensor 420. Specifically, when the second self-priming pump 200 is operating normally, due to the action of the second self-priming pump 200 and the first self-priming pump 100, the air pressure at the mouth of the air supply device 400 will fluctuate. When the pressure sensor 420 detects that the pressure is always in a fluctuating state, it is operating normally. When the first self-priming pump 100 and the second self-priming pump 200 stop running, only the air supply device 400 is supplying air normally at this time, so the air pressure is stable. By detecting the continuous and stable air pressure, the control system can recognize that the self-priming pump is in a stopped state, so the air supply device 400 can be controlled to stop supplying air.

[0040] Furthermore, the self-priming force of the second self-priming pump 200 is greater than the self-priming force of the first self-priming pump 100. In this embodiment, when the first self-priming pump 100 inputs liquid into the connecting piece 300, the second self-priming pump 200 can discharge all the liquid, and at the same time, the second self-priming pump 200 can extract all the gas output by the gas supply device 400, thereby preventing the liquid pumped by the first self-priming pump 100 from entering the gas supply device 400.

[0041] Further, even refer to Figure 4 , the connector 300 includes a shell 310 and an air pipe 320. A partition 330 is provided in the shell 310, and the partition 330 forms two independent first cavities 301 and second cavities 302 in the shell 310. A first pipe joint and a second pipe joint are extended at both ends of the first cavity 301, the first self-priming pump 100 is connected to the first pipe joint, and the second self-priming pump 200 is connected to the second pipe joint. The air pipe 320 is arranged in the second cavity 302, and one end of the air pipe 320 passes through the shell and is connected to the air supply device 400, and the other end passes through the partition and communicates with the first cavity 301. In this embodiment, the first self-priming pump 100 pumps liquid into the first cavity 301, and the air supply device 400 inputs gas into the first cavity 301 through the air pipe 320; then the second self-priming pump 200 pumps out all the liquid and gas in the first cavity 301.

[0042] Further, refer to Figure 4 , the air pipe 320 is a multi-section U-shaped structure. In this embodiment, by configuring the air pipe 320 to be a multi-section U-shaped structure, the liquid entering the first cavity 301 can be further prevented from entering the air supply device 400 again.

[0043] Further, refer to Figure 4 , a rectangular hole is provided on the partition 330, and a flat gas nozzle 321 located in the rectangular hole is provided at the end of the gas pipe 320. In this embodiment, the flat gas nozzle 321 is provided at the end of the gas pipe 320, so that the width of the gas outlet can be reduced, and liquid can be further prevented from entering, but normal gas output can be ensured.

[0044] Further, refer to Figure 4 The first cavity 301 is a circular cavity, and a screw 340 is also disposed in the first cavity, and the screw 340 and the inner wall of the first cavity 301 form a spiral flow channel 341. In this embodiment, the liquid and the gas can be transported in a spiral manner in the connector 300, which can increase the mixing strength of the gas and the liquid and increase the gas content in the liquid.

[0045] Furthermore, the connector 300 may also be an electronic three-way valve, through which the first self-priming pump 100, the second self-priming pump 200 and the air supply device 300 are connected. The air supply device 400 is a constant pressure air supply device, which may be a combination of an air tank and an air pump.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
