[0034] The balancing pipeline includes a sixth channel 6, a third solenoid valve 14, and a seventh pipe 7. The defoaming tank 10, the sixth channel 6, the third solenoid valve 14, the seventh pipe 7, and the temporary storage tank 11 are connected in sequence.

[0037] The device also includes a first liquid level sensor 18 and a second liquid level sensor 19, wherein the first liquid level sensor 18 is installed in the defoaming tank 10 and the second liquid level sensor 19 is installed in the temporary storage tank 11.

[0038] In this embodiment, the left side of the defoaming tank 10 is connected to a second pipe 2, and the first pipe 1 is connected to the second pipe 2 via a first solenoid valve 12 and extends to the outside of the cabinet. The upper side is connected to the second solenoid valve 13 via a third pipe 3, and then connected to the vacuum pump 16 via a fourth pipe 4. The vacuum pump 16 is installed in the upper right corner inside the cabinet and finally extends to the outside of the cabinet via a fifth pipe 5. The right side is connected to the third solenoid valve 14 via a sixth pipe 6, and connected to the temporary storage tank 11 via a seventh pipe 7. An eighth pipe 8 is provided on the lower surface of the temporary storage tank 11, which is connected to the fourth solenoid valve 5 and extends to the lower surface of the defoaming tank 10.

[0040] A control panel 17 is provided on the surface of the cabinet, which integrates four function buttons: start button, stop button, reset button and pause button; four casters are provided at the bottom of the cabinet to facilitate the overall movement of the device.

[0041] The working process of this utility model is as follows:

[0042] S1: After the system starts, all solenoid valves are in the closed state by default; open the first solenoid valve 12, which is connected to the first pipe 1 on the left side of the deaerator 10. After opening, external fluid can flow into the deaerator 10 through the second pipe 2, which is the only passage for fluid to enter the deaerator 10.

[0043] S2: Close the second solenoid valve 13, the third solenoid valve 14, and the fourth solenoid valve 15, and let the liquid flow into the defoaming tank 10 through the second pipe 2;

[0044] Close the second solenoid valve 13: to prevent the vacuum pump 20 from starting accidentally during non-working phases, and to prevent the defoaming tank 10 from pumping air when no fluid is injected, causing it to run dry or waste energy.

[0045] Close the third solenoid valve 14: to prevent the liquid from flowing into the temporary storage tank 11 through the seventh pipe 7 without treatment when the defoaming tank 10 has not completed defoaming, thus disrupting the defoaming process.

[0046] Close the fourth solenoid valve 15: prevent liquid (if there is any residue) in the temporary storage tank 11 from flowing back into the defoaming tank 10 through the eighth solenoid valve 8, and ensure that the fluid is input according to the preset path.

[0047] S3: When the first liquid level sensor 18 detects that the liquid in the defoaming tank 10 has reached the preset height, the ultrasonic vibrator 16 is activated. Using the cavitation effect of ultrasound, the microbubbles suspended in the liquid are aggregated into large bubbles with high buoyancy. The large bubbles rise to the top of the liquid and burst to release gas.

[0048] S4: Open the second solenoid valve 13. At this time, the bubbles in the debubbling tank 10 have completed coalescence. The second solenoid valve 13 is connected to the vacuum pump 20. The fourth pipe 4 and the fifth pipe 5 form a gas extraction passage, so that the vacuum pump 20 absorbs the gas generated by the bursting of bubbles in the debubbling tank 10 and discharges it through the gas outlet connected to the fifth pipe 5. At the same time, the ultrasonic vibrator 16 continues to work to further process the remaining microbubbles, realizing the coordinated operation of vibration debubbling and gas extraction.

[0049] S5: Open the third solenoid valve 14 and the fourth solenoid valve 15;

[0050] Open the third solenoid valve 14: open the passage from the sixth pipe 6 on the right side of the defoaming tank 10 to the temporary storage tank 11 (via the seventh pipe 7), so that the defoamed liquid in the defoaming tank 10 flows into the temporary storage tank 11.

[0051] Open the fourth solenoid valve 15: connect the eighth pipe 8 on the lower surface of the temporary storage tank 11 to the circuit on the lower surface of the defoaming tank 10 to ensure fluid flow pressure balance. At the same time, in conjunction with the third solenoid valve 14, the liquid is finally discharged through the ninth pipe 9 of the temporary storage tank 11, completing the entire online fluid defoaming process.

[0052] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
