[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0025] Embodiment 1

[0026] Reference Figure 1 As shown, a vacuum breaking device of the utility model is used to break the vacuum of a vacuum solvent cleaning machine, comprising:

[0027] Inert gas supply device 1;

[0028] A gas supply pipeline 2, one end of which is connected to the output end of the inert gas supply device 1, and the other end of which is connected to the vacuum tank of the vacuum solvent cleaning machine;

[0029] The balancing pipeline 3 has one end connected to the air supply pipeline 2 and the other end connected to a one-way valve 4. The input end of the one-way valve 4 is connected to the balancing pipeline 3, and the output end of the one-way valve 4 is connected to the atmosphere.

[0030] Principle of use: When the vacuum solvent cleaning machine 5 is broken, since the vacuum tank 6 of the vacuum solvent cleaning machine 5 is in a vacuum state, the pressure inside the vacuum tank 5 is less than the atmospheric pressure, so the inert gas output by the inert gas supply device 1 will enter the vacuum tank 6 through the gas supply pipeline 2 and will not escape from the balance pipeline 3; when the vacuum is broken, that is, the pressure in the vacuum tank 6 is equal to the atmospheric pressure, the inert gas output by the inert gas supply device 1 will be discharged to the atmosphere through the balance pipeline 3 and the one-way valve 4 (the pressure in the vacuum tank will not be greater than the atmospheric pressure, that is, it will not be in a positive pressure state); that is, when inert gas is discharged from the balance pipeline 3, the vacuum is broken. It can be imagined that when the vacuum breaking device is used to break the vacuum, there is no need for the staff to measure the pressure in the vacuum tank 6 through the pressure detection device or other methods to determine whether the vacuum breaking work is completed, which reduces the labor intensity and difficulty of the staff, and the pressure in the vacuum tank will not be too high during the entire vacuum breaking process, which can avoid damage to the vacuum solvent cleaning machine and also improve the safety of the vacuum breaking process; at the same time, compared with the air vacuum breaking method, the vacuum breaking device uses the method of inputting inert gas into the vacuum tank to break the vacuum, which does not have the risk of combustion and explosion, and is safer and more reliable.

[0031] Furthermore, the gas supply pipeline 2 includes a first gas supply pipeline 21 and a second gas supply pipeline 22, one end of the first gas supply pipeline 21 is connected to the output end of the inert gas supply device 1, and the other end is connected to one end of the second gas supply pipeline 22, the other end of the second gas supply pipeline 22 is connected to the vacuum tank of the vacuum solvent cleaning machine, and a first solenoid valve 23 is provided on the first gas supply pipeline 21, and a second solenoid valve 24 is provided on the second gas supply pipeline 22, one end of the balancing pipeline 3 is connected to the first gas supply pipeline 21 or the second gas supply pipeline 22, and the balancing pipeline 3 is located between the first solenoid valve 23 and the second solenoid valve 24.

[0032] Furthermore, the diameter of the first air supply pipeline 21 is smaller than the diameter of the second air supply pipeline 22 .

[0033] Furthermore, the first gas supply pipeline 21 and the second gas supply pipeline 22 are connected via a three-way valve, and the balance pipeline 3 is connected to the first gas supply pipeline 21 and the second gas supply pipeline 22 via a three-way valve.

[0034] Furthermore, the inert gas supply device 1 is a nitrogen supply device, but is not limited to a nitrogen supply device.

[0035] Furthermore, the inert gas supply device 1 is a nitrogen tank filled with nitrogen, and the gas pressure in the nitrogen tank is 2 bar-3 bar.

[0036] Furthermore, a carrying trolley is included, and the inert gas supply device 1, the gas supply pipeline 2 and the balance pipeline 3 are all connected to the carrying trolley; the vacuum breaking device can be moved to any working position through the carrying trolley.

[0037] Embodiment 2

[0038] Reference Figure 2 As shown, on the basis of the first embodiment, further, the output end of the one-way valve 4 is connected to a pressure monitoring pipeline 7 , and a pressure sensor 8 is provided in the pressure monitoring pipeline 7 .

[0039] Furthermore, the system further comprises a controller 9 , which is respectively connected to the inert gas supply device 1 , the pressure sensor 8 , the first solenoid valve 23 and the second solenoid valve 24 .

[0040] Specifically, when the vacuum breaking work is completed, the inert gas output by the inert gas supply device 1 will be discharged into the atmosphere through the balance pipeline 3, the one-way valve 4 and the pressure monitoring pipeline 7. The pressure in the pressure monitoring pipeline 7 changes, thereby triggering the pressure sensor 8. The pressure sensor 8 transmits the signal to the controller 9. The controller 9 controls the inert gas supply device 1 to stop running and close the first solenoid valve 23 and the second solenoid valve 24 to realize automatic control of the vacuum breaking process.

[0043] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
