When the existing micro-nano bubble generating devices mix oxygen, ozone, etc. with liquid, an external gas source is required. Specifically, a gas storage cylinder for storing gas needs to be connected. When a gas storage cylinder with a small storage capacity is connected, the gas storage cylinder needs to be frequently replaced, resulting in high labor intensity for workers and high labor costs, affecting the operation of the micro-nano bubble generating device and the efficiency of micro-nano bubble generation. When a gas storage cylinder with a large storage capacity is used, the volume of the gas storage cylinder is large, making it very inconvenient to carry, and it is also very troublesome to replace, requiring a long time for replacement, which affects the efficiency of micro-nano bubble generation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The following is a detailed description in conjunction with the drawings and specific embodiments. Many specific details are set forth in the following description in order to provide a thorough understanding of the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0027] The integrated micro-nano bubble generating device of the present application can be used in situations where liquid is mixed with various pure gases for a long time to generate bubble water, and of course it can also be used in other similar application scenarios. A micro-nano bubble generating device for emergency treatment is described in detail below.

[0028] See attached Figure 1 — Figure 7 As shown, a schematic structural diagram of a preferred embodiment of an integrated micro-nano bubble generating device of the present application is shown. The micro-nano bubble generating device, wherein, comprises a frame 1, a partitioning horizontal plate 11 installed on the frame 1, a partitioning vertical plate 12 installed on the frame 1, a gas source structure 2 for generating gas installed on the top of the partitioning horizontal plate 11, a gas storage structure 3 installed on the frame 1 and connected to the gas source structure 2, a bubble generating assembly 4 installed on the frame 1 and connected to the gas storage structure 3; a protective plate 5 is installed on the frame 1, a heat dissipation structure 6 for dissipating heat from the gas source structure 2 is installed on the protective plate 5, and a controller 8 is installed on the partitioning horizontal plate 11.

[0029] The utility model is used to provide an installation position for the gas source structure 2 and the controller 8 through the setting of the dividing cross plate 11; the gas source structure 2 is used to generate pure gas for subsequent gas-liquid mixing; the gas storage structure 3 is used to temporarily store the gas to prevent the speed of gas generation by the gas source structure 2 from not matching the speed of gas consumption, which would affect the normal operation of the device. Specifically, if the gas generated by the gas source structure 2 is not temporarily stored in the gas storage structure 3, it can only be directly transported to the gas-liquid mixing pump 41 through a pipeline for gas-liquid mixing. The speed of gas generation by the gas source structure 2 is relatively stable, so the gas flow rate cannot be controlled, which would affect the normal operation of the device; the bubble generating component 4 is used to mix gas and liquid to generate a gas-liquid mixture; the heat dissipation structure 6 can be used to dissipate heat from the gas source structure 2 to prevent the gas source structure 2 from overheating and affecting the normal operation of the device.

[0030] See attached Figure 1 and Figure 2 As shown, in the present invention, the partition vertical plate 12 separates the air source structure 2 and the controller 8 installed on the top of the partition horizontal plate 11; and a universal wheel 9 is installed at the bottom of the frame 1.

[0031] The utility model makes the micro-nano bubble generating device easy to move by setting the universal wheel 9, so that when an emergency occurs, the staff can quickly move the generating device to the scene for emergency treatment, thereby improving the response speed of the micro-nano bubble generating device. Combined with the setting of the gas source structure 2 and the gas storage structure 3, continuous gas production can be carried out, thereby continuously mixing gas and liquid, thereby enhancing the emergency treatment capability of the micro-nano bubble generating device.

[0032] Refer to the attached Figure 2 and Figure 3 As shown, in the present utility model, the gas source structure 2 includes a gas generating device 21 installed on the top of the partition cross plate 11, and a first intake pipe 22 installed at the air outlet of the gas generating device 21. The first intake pipe 22 is connected to the gas storage structure 3.

[0033] By setting the gas generating device 21 in the present utility model, corresponding gas can be generated, the continuous working time of the micro-nano bubble generating device can be extended, the efficiency of generating micro-nano bubbles by the micro-nano bubble generating device can be improved, so that the staff does not need to frequently replace the gas cylinder, thereby reducing the labor intensity of the staff and reducing the labor cost; through the setting of the first intake pipe 22, it is used to guide the gas generated by the gas generating device 21, so that the gas can enter the gas storage cylinder 31.

[0034] Refer to the attached Figure 3 and Figure 4 As shown, in the present utility model, the gas storage structure 3 includes a gas storage cylinder 31 installed on the frame 1, a guide pipe 32 installed at the air outlet of the gas storage cylinder 31, and a pressure increasing valve 33 installed at the air inlet of the gas storage cylinder 31. The pressure increasing valve 33 is communicated with the first intake pipe 22, and the guide pipe 32 is connected to the bubble generating assembly 4.

[0035] By setting the gas storage cylinder 31 in the present utility model, it is used to temporarily store the made gas, ensuring that the subsequent bubble generating assembly 4 can perform gas-liquid mixing at any time without the need for temporary gas production, thereby avoiding the time spent on temporary gas production and improving the response speed of the micro-nano bubble generating device; through the setting of the guide pipe 32, it is used to guide the gas when the gas storage cylinder 31 discharges gas; through the setting of the pressure increasing valve 33, it is ensured that the gas made by the gas generating device 21 can enter the gas storage cylinder 31, preventing the gas in the gas storage cylinder 31 from flowing out from the air inlet, ensuring the normal gas flow at the air inlet and air outlet of the gas storage cylinder 31, and enabling the gas storage cylinder 31 to store and discharge gas normally.

[0036] Refer to the attached Figure 3 and Figure 4 As shown, in the present utility model, a safety structure 7 is further installed on the gas storage cylinder 31, and a first exhaust valve 34 is installed at one end of the gas storage cylinder 31.

[0037] The utility model is provided with a safety structure 7 for protecting the gas storage cylinder 31, preventing the gas pressure in the gas storage cylinder 31 from being too high, which may cause the gas storage cylinder 31 to be damaged or even explode, thus ensuring the safety of the equipment and providing protection for the personal safety of workers. The first exhaust valve 34 is provided to discharge the gas with insufficient purity in the gas storage cylinder 31, ensuring the purity of the gas in the gas storage cylinder 31. Specifically, when the device has not been used for a long time, or after part of the gas in the gas storage cylinder 31 has been used and it is no longer needed for a long time in the future, the gas in the gas storage cylinder 31 can be released to prevent the device from being accidentally opened and avoid problems when generating micro-nano bubbles. Moreover, the gas in the gas storage cylinder 31 of the micro-nano bubble generating device for emergency treatment needs to be replaced regularly. Therefore, the first exhaust valve 34 is required to discharge the gas to ensure the purity of the gas in the gas storage cylinder 31 of the micro-nano bubble generating device for emergency treatment and ensure the emergency response speed of the micro-nano bubble generating device.

[0038] Refer to the attached Figure 4 As shown, in the utility model, the safety structure 7 includes a safety pipe 71 installed on the gas storage cylinder 31 and communicating with the inside of the gas storage cylinder 31, a safety valve 72 installed on the safety pipe 71, and a first pressure gauge 73 installed on the safety pipe 71.

[0039] The utility model provides an installation position for the safety valve 72 through the setting of the safety pipe 71. Through the setting of the first pressure gauge 73, the first pressure gauge 73 is an electric contact pressure gauge and is connected to the controller 8, and the pressure can be read in real time through the controller 8. When the pressure read by the first pressure gauge 73 is too large or too small, the controller 8 can control the gas generating device 21 to stop or work. Specifically, when the first pressure gauge 73 senses that the gas pressure in the gas storage cylinder 31 reaches or exceeds the maximum pressure set by the staff in the controller 8, it means that the gas storage in the gas storage cylinder 31 is completed, and the gas generating device 21 needs to stop working to avoid danger caused by the further increase of the gas in the gas storage cylinder 31. When the first pressure gauge 73 senses that the gas pressure in the gas storage cylinder 31 reaches or is less than the minimum pressure set by the staff in the controller 8, it means that the gas in the gas storage cylinder 31 will not be sufficient for the subsequent gas-liquid mixing, and the gas in the gas storage cylinder 31 needs to be replenished in time.

[0040] Refer to the attached Figure 4 — Figure 6As shown in the figure, in the present utility model, the bubble generating assembly 4 includes a gas-liquid mixing pump 41 installed on the frame 1, a liquid inlet pipe 42 installed at the feeding position of the gas-liquid mixing pump 41, a second air inlet pipe 43 installed at the feeding position of the gas-liquid mixing pump 41, a gas flow meter 44 installed on the second air inlet pipe 43, a bubble liquid outlet pipe 45 installed at the discharging end of the gas-liquid mixing pump 41, and a gas distributing row 46 installed at one end of the second air inlet pipe 43 away from the gas-liquid mixing pump 41. The gas distributing row 46 is connected to the air guide pipe 32.

[0041] In the present utility model, through the setting of the gas-liquid mixing pump 41, it is used to mix gas and liquid to generate a gas-liquid mixture; through the setting of the liquid inlet pipe 42, it is used to guide the liquid so that the liquid can smoothly enter the gas-liquid mixing pump 41; through the setting of the second air inlet pipe 43, it is used to guide the gas so that air or pure gas enters the gas-liquid mixing pump 41. It should be particularly noted that a one-way valve is provided on the second air inlet pipe 43 to prevent gas backflow; through the setting of the gas flow meter 44, it can be used to monitor the gas flow. When the gas flow is too large or too small, the opening degree of the solenoid valve on the air guide pipe 32 or the air inlet pipe 441 can be controlled by the controller 8 to adjust the gas flow, thereby regulating the gas flow.

[0042] Refer to the appendix Figure 3 — Figure 5 As shown in the figure, an air inlet pipe 441 directly connected to the control is also provided on the gas distributing row 46, and solenoid valves 47 are provided on both the air inlet pipe 441 and the air guide pipe 32.

[0043] In the present utility model, through the setting of the air inlet pipe 441, it is directly connected to the air, so that the gas-liquid mixing pump 41 can mix air and liquid; through the setting of the solenoid valve 47, it can be used to control the gas flow of the air guide pipe 32 and the air inlet pipe 441, thereby controlling the mixing ratio of gas and liquid, and generating bubble water (gas-liquid mixture) with different bubble concentrations.

[0044] Refer to the appendix Figure 5 and Figure 6 As shown in the figure, in the present utility model, a second pressure gauge 451, a gas dissolving chamber 452, and an electromagnetic water valve 453 are sequentially provided on the bubble liquid outlet pipe 45 along the flowing direction of the gas-liquid mixture; a second exhaust valve 454 is installed on the gas dissolving chamber 452.

[0045] With the setting of the second pressure gauge 451, the present utility model can monitor the state of gas-liquid mixture. Specifically, the second pressure gauge 451 is installed on the bubble liquid outlet pipe 45. Then, in the case of no bubbles or extremely few bubbles, the reading of the pressure gauge is recorded as the reference value, representing the normal pressure state of the fluid in the pipeline. Then, start observing and recording the reading of the pressure gauge. As the bubbles move or gather in the pipeline, the reading of the second pressure gauge 451 will change, thereby monitoring the state of the bubble water.

[0046] Refer to the appendix Figure 7 As shown in the figure, in the present utility model, the heat dissipation structure 6 includes ventilation holes 61 provided on the protection plate 5, a heat dissipation fan 62 installed on the protection plate 5 at the position of the ventilation holes 61, and a grille plate 63 is installed at the ventilation holes 61.

[0047] With the setting of the ventilation holes 61, the installation position of the heat dissipation structure 6 is defined, and the space where the gas generating device 21 is installed can be communicated with the external space, enabling the internal and external air to circulate. It should be particularly noted that in addition to the two ventilation holes 61, there are other gaps in the space where the gas generating device 21 is located, and it is not completely sealed. Therefore, air can enter through the gap between the door body and the frame 1, or through other provided communication holes; with the setting of the heat dissipation fan 62, the gas outside the frame 1 can be inhaled into the space where the gas generating device 21 is located, or the gas in the space where the gas generating device 21 is located can be pumped outwards, thereby controlling the temperature of the space where the gas generating device 21 is located, preventing damage to the control equipment, pipelines, and related components due to overheating of the gas, and thus ensuring the service life of the gas generating device 21; with the setting of the grille plate 63, it protects the workers, preventing the workers from accidentally contacting their arms with the heat dissipation fan 62 and providing guarantee for the personal safety of the workers.

[0048] Refer to the appendix Figure 1 — Figure 7 As shown in the figure, the using process of the present utility model is as follows:

[0049] The staff selects to mix air with liquid, or pure gas with liquid through the controller 8; after the selection is completed, the device is started to work through the controller 8.

[0050] When the staff selects to mix air and liquid, the controller 8 controls the solenoid valve 47 on the air inlet pipe 441 to open and the solenoid valve 47 on the air duct 32 to close, so that air can enter the air distribution row 46 along the air inlet pipe 441, move along the second inlet pipe 43 through the air distribution row 46, pass through the gas flowmeter 44 during the movement in the second inlet pipe 43, and then enter the gas-liquid mixing pump 41. At the same time, the liquid enters the gas-liquid mixing pump 41 through the liquid inlet pipe 42 for gas-liquid mixing, and the mixed bubble water (gas-liquid mixture) flows out through the bubble liquid outlet pipe 45;

[0051] When the staff selects to mix pure gas and liquid, first, the controller 8 monitors whether the air pressure in the gas storage cylinder 31 is within the specified pressure range through the first pressure gauge 73. If it is higher than the specified minimum pressure, at this time, the controller 8 opens the solenoid valve 47 on the air duct 32 and closes the solenoid valve 47 on the air inlet pipe 441. The pure gas in the gas storage cylinder 31 enters the air distribution row 46 through the air duct 32, moves along the second inlet pipe 43 through the air distribution row 46, passes through the gas flowmeter 44 during the movement in the second inlet pipe 43, and then enters the gas-liquid mixing pump 41. At the same time, the liquid enters the gas-liquid mixing pump 41 through the liquid inlet pipe 42 for gas-liquid mixing, and the mixed bubble water (gas-liquid mixture) flows out through the bubble liquid outlet pipe 45; When the air pressure in the controller 8 is lower than the specified value, the controller 8 controls the gas generating device 21 to start working, generates pure gas and fills the gas into the gas storage cylinder 31 through the first inlet pipe 22 in cooperation with the booster valve 33; It should be particularly noted that the specified air pressure value for the controller 8 to control the gas generating device 21 to work is within the specified air pressure range when the first pressure gauge 73 detects the gas storage cylinder 31. When the controller 8 is started, if the air pressure is lower than the minimum value of the specified air pressure range, at this time, the controller 8 will not open the two solenoid valves 47, nor start the gas-liquid mixing pump 41, but first start the gas generating device 21 until the air pressure in the gas storage cylinder 31 reaches the maximum value of the specified range, and the gas generation speed of the gas generating device 21 is greater than the exhaust speed of the gas storage cylinder 31. Specifically, when the gas generating device 21 starts to generate gas, even if all the solenoid valves 47 on the air duct 32 are opened, the volume of gas entering the gas storage cylinder 31 in the same time is greater than the volume of gas leaving the gas storage cylinder 31.

[0052] It should be particularly noted that the controller 8 can monitor the gas flow through the gas flowmeter 44, and cooperate with the solenoid valve 47 to accurately control the gas flow in the air inlet pipe and the air duct 32, so that the mixing ratio of gas and liquid can be controlled.

[0053] The above embodiments are descriptions of this application, not limitations on this application. Any simple transformation of this application belongs to the protection scope of this application.
