The tank body is provided with a pneumatic wafer valve control tube 1 10 and a pneumatic wafer valve control tube 2 11 for controlling the opening and closing of the pneumatic wafer valve.

The cylinder body 8 is provided with a maintenance manhole 14 or a liquid level gauge 15 .

The bottom of the tank is provided with feet 2 for supporting the tank.

The Unicom pipeline 17 is provided with a Unicom valve 4, which is used to open or close the upper and lower parts of the vacuum buffer tank. The diameter of the Unicom pipeline 17 is smaller or equivalent to that of the vacuum outlet 7. The influence of fluctuations in Table 1 can be almost ignored. When the reading of Vacuum Gauge 2 is consistent with that of Vacuum Gauge 1, opening the pneumatic wafer valve will not affect the vacuum degree in the vacuum buffer tank.

Preferably, the liquid discharge valve 1, the communication valve 4, and the pneumatic wafer valve 13 can all be automatically controlled, and automatic continuous liquid discharge can be realized through automatic control.

The specific operation process of the utility model vacuum buffer tank is:

The liquid accumulation position of the vacuum buffer tank can be seen through the maintenance manhole 14, or through the liquid level gauge 15, when the liquid discharge operation is required, first close the Unicom valve 4 and the pneumatic wafer valve 13, and open the liquid discharge valve 1; After the effusion is exhausted, close the drain valve 1, open the connecting valve 4, observe the vacuum gauge 2 12, and when the reading of the vacuum gauge 2 12 is consistent with the vacuum gauge 1 9, open the pneumatic wafer valve 13. That is to complete a liquid discharge cycle; the process is repeated in this way.

The beneficial effects of the utility model:

(1) The utility model vacuum buffer tank is simple in structure and easy to operate;

(2) The vacuum buffer tank of the utility model can complete the liquid discharge without affecting the vacuum degree, without affecting the continuous production, ensuring the vacuum state in the tank, improving the precision control level in the production process, reducing waste of resources, and reducing equipment maintenance and replacement times, reducing production costs.
