[0038] The present application intends to provide a vacuum detection device that can not only realize vacuum detection, but also realize vacuuming, thereby realizing the diversity of the functions of the vacuum detection device.

[0039] Figure 1 A schematic diagram of the structure of the device provided in the embodiment of the present application is shown in FIG. Figure 1 As shown, an embodiment of the present application provides a vacuum detection device, which includes: a mounting frame 1, a vacuum unit 2, an exhaust pipe 3, a vacuum pipe 4, a detection tube 5 and a vacuum detection unit 6, wherein the vacuum unit 2 is mounted on the mounting frame 1; the exhaust pipe 3 is connected to the vacuum unit 2; one end of the vacuum pipe 4 is connected to the vacuum unit 2, and the other end of the vacuum pipe 4 is configured to be connected to a vacuum tank; the detection tube 5 is connected to the vacuum pipe 4; and the vacuum detection unit 6 is mounted on the detection tube 5.

[0040] The device integrates the vacuum pumping unit 2 and the vacuum detection unit 6 into one body for coordinated use, thereby achieving vacuum pumping while realizing vacuum detection, thereby realizing the diversity of functions of the vacuum detection device.

[0041] In some embodiments, the vacuum unit 2 may be an XDS dry scroll pump, which is provided with a bearing cover that can isolate the vacuum environment from all forms of lubricants, creating a completely statically sealed and completely oil-free clean vacuum environment to meet cleanliness requirements.

[0042] In some embodiments, the device further includes a purge pipe 7, one end of the purge pipe 7 is connected to the detection tube 5, and the other end of the purge pipe 7 is configured to be connected to a purge unit. By setting the purge pipe 7, after the purge unit is connected, the vacuum tank can be purged. It should be noted that the purge pipe 7 ultimately wants to be connected to the vacuum tank to achieve whistle blowing. One way provided in the embodiment of the present application is that the purge pipe 7 is connected to the vacuum tank through the detection tube 5 and the vacuum tube 4. It can be understood by those skilled in the art that the purge pipe 7 can be connected to the vacuum tube 4 to achieve communication with the vacuum tank through the vacuum tube 4, or the purge pipe 7 can be directly connected to the vacuum tank to achieve direct communication with the vacuum tank.

[0043] In some embodiments, the device further includes a pressure detection unit 8, which is mounted on the purge pipe 7. The purge pressure can be detected by the pressure detection unit 8. It should be noted that the pressure detection unit 8 can be set at any position on the pipeline connecting the purge unit and the vacuum tank, for example, the detection pipe 5, the vacuum pipe 4, etc.

[0044] In some embodiments, the vacuum tube 4 includes a tube body 41 and a conduit 42, which are interconnected. The end of the tube body 41 remote from the conduit 42 is connected to the vacuum unit 2, and the end of the conduit 42 remote from the tube body 41 is configured to connect to a vacuum tank. The tube body 41 and conduit 42 can be connected via a VCR connector, and the conduit 42 can be a Pigtail tube. Furthermore, those skilled in the art can provide a pipe support to secure the tube body 41 as needed to prevent it from loosening or falling off.

[0045] Furthermore, the tube body 41 is provided with a hose section 411, which is located near one end of the conduit 42. The hose section 411 may be a metal hose. The hose section 411 can be rotated in various directions, making it easier to connect the vacuum tanks in a certain area.

[0046] In this embodiment, the front section of the tube body 41 can be made of SS316L, which serves as a pipeline connection. Flanges are welded at both ends, one end is connected to the inlet of the vacuum unit 2, and the other end is connected to the hose section 411.

[0047] In some embodiments, the device further includes a power supply unit, which is mounted on the mounting frame 1 and connected to the vacuum unit 2. The provision of the power supply unit allows the vacuum tank to be vacuumed at any location without being restricted by power supply conditions in the usage scenario.

[0052] The whole device is a vacuum tank vacuuming process including a purging process and a vacuuming process, wherein the purging process is: open the two valves of the vacuum tank at the same time, one of the valves is connected to the vacuum pipe 4, and the other is emptied, and then the purge gas N2 is introduced into the purge pipe 7, and the vacuum tank is purged with N2, while the pressure of the purged N2 is monitored in real time through the pressure detection unit 8 to prevent insufficient pressure. After purging for a period of time, close the venting valve, and then carry out the vacuuming process. The vacuuming process is: connect the vacuuming unit 2 to the power supply to start the work, the vacuuming unit 2 begins to continuously extract the gas in the vacuum tank through the vacuum pipe 4, and the extracted gas is discharged into the environment through the exhaust pipe 3, and the vacuum detection unit 6 displays the pressure in the vacuum tank in real time. Observe the value of the vacuum detection unit 6 until it meets the requirements, close the valve connecting the vacuum tank to the vacuum pipe 4, and close the vacuum tank.
