[0013] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1 , 2 As shown, this embodiment of a laboratory solution deoxygenation device includes a tank 1, with an upper cover 2 at the top and a lower cover 3 at the bottom, sealing the inner cavity of the tank. A circulation pipe 9 connects the upper cover 2 and the lower cover 3, allowing the circulation pipe 9 to communicate with the inner cavity of the tank 1. A water inlet pipe 11 is connected to the circulation pipe 9, allowing the solution requiring deoxygenation to flow into the tank 1 through the water inlet pipe 11 and the circulation pipe 9, thus achieving a circulation flow between the circulation pipe and the tank. An air inlet pipe 14, a liquid outlet pipe 15, and an exhaust pipe 4 are connected to the upper cover 2. A bubbling device 16 is provided inside the tank 1. One end of the air inlet pipe 14 extends into the inner cavity of the tank 1 and is connected to the inlet of the bubbling device 16. Inert gas is introduced into the bubbling device 16 through the air inlet pipe 14, and the bubbling device 16 blows out inert gas to purge and deoxygenate the solution. One end of the liquid outlet pipe 15 extends into the inner cavity of the tank 1, and after the solution is deoxygenated, the solution in the tank is discharged through the liquid outlet pipe. During the deoxygenation process, exhaust pipe 4 is used to discharge the gas inside tank 1 to prevent excessive pressure in the tank.

[0015] The aforementioned inlet pipe 11 is equipped with an inlet valve 12, the circulation pipe 9 with a circulation valve 13, the air inlet pipe 14 with an air inlet valve 8, the liquid outlet pipe 15 with a liquid outlet valve 7, and the exhaust pipe 4 with an exhaust valve 5. The on / off state of each valve controls the flow of the corresponding pipes. The circulation valve 13 is located below the connection between the inlet pipe 11 and the circulation pipe 9. When the circulation valve is closed, the circulation pipe above the connection with the inlet pipe remains open. A circulation pump 10 is also installed on the circulation pipe, located above the connection between the inlet pipe and the circulation pipe.

[0016] The bubbling device 16 includes a bubbling body, which has a gas collecting chamber 16.1 connected to an inlet pipe 14. A perforated plate 16.2 is provided above the gas collecting chamber 16.1, and a disperser 16.3 is connected to the perforated plate 16.2. The bubbling device introduces inert gas into the solution to purge and deoxygenate the solution.

[0017] Pressure gauge 6 is installed on exhaust pipe 4 to observe the pressure inside the tank.

[0018] The working principle is as follows: Open the inlet valve and close the circulation valve to inject the solution requiring deoxygenation into the tank through the inlet and circulation pipes. Close the inlet valve and open the circulation valve to start the circulation pump, allowing the solution to circulate between the circulation pipes and the tank. Open the inlet and outlet valves, and nitrogen gas enters the gas collection chamber of the bubbling device through the inlet pipe. Nitrogen gas is then introduced into the solution in the tank through the perforated plate and disperser, thereby deoxygenating the solution. After deoxygenation is complete, close the outlet valve, allowing the pressure inside the tank to be read through the pressure gauge, ensuring a certain pressure within the tank. When discharging the solution, open the outlet valve, and use pressure to discharge the solution from the tank into the test container.

[0019] This application features a compact structure, small footprint, and simple operation, eliminating the need for complex manual procedures and improving work efficiency. By introducing inert gas into the solution through a bubbling device, deoxygenation efficiency is improved, quickly achieving the required low-oxygen level. Furthermore, the solution is discharged through the pressure difference between the inside and outside of the tank, reducing electricity consumption and increasing energy efficiency.

[0020] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
