The diversion type gas-liquid separation assembly is isolated at the feeding filling valve and the discharging filling valve, and the air inside the shell is extracted through the vacuum generator so as to reduce the air pressure inside the shell. After maintaining the low pressure state for a period of time, the small bubbles in the diversion type gas-liquid separation component rise along the same trend until the bubbles disappear. And filling the defoaming three-proofing agent into the container through a discharge filling valve. Because the three proofings dosage that water conservancy diversion formula gas-liquid separation subassembly can hold is few, and the volume that can the filling after removing the bubble at every turn is just few, consequently this technical scheme has the use defect, frequent opening promptly for the filling work's of three proofings agent inefficiency.

Under the condition that the valves are all turned off, the negative pressure bin is isolated from the outside, and after air in the cavity of the negative pressure bin is continuously extracted through the negative pressure generator, the negative pressure condition can be maintained in the negative pressure bin. The air pressure of the bubbles in the three-proofing agent is larger than the air pressure of the negative pressure condition established in the negative pressure bin, so that the bubbles in the three-proofing agent are forced to grow and float upwards under the action of pressure difference until the bubbles break away from the three-proofing agent and enter the cavity of the negative pressure bin. The liquid storage tank does reciprocating motion, the three-proofing agent in the liquid storage tank is shaken, and the three-proofing agent slowly flows, so that bubbles in the three-proofing agent can float upwards. After the three-proofing agent is shaken, the three-proofing agent flows to ensure that any fine bubbles move towards the liquid level along with the flowing three-proofing agent, so that the bubbles can be promoted to move upwards without providing an attachment surface for the bubbles. The relatively closed guide structure in the prior art is avoided, so that a large amount of three-proofing agent can be loaded in the liquid storage tank for defoaming operation.

After the bubbles in the three-proofing agent of rocking meet the guide post, the bubbles can be attached to the early guide post to the process that the bubbles gathered, the guide post can be attached to the bubble at last and the situation come-up. When the three-proofing agent is used, the three-proofing agent submerges into the three-proofing agent after passing through the top of the guide column, so that the situation that the top of the guide column is exposed above the liquid level can be avoided, and in the situation, the turbulent flow exceeds the liquid level, and the turbulent flow possibly wraps air and then falls back, so that new air bubbles are doped.

The three-proofing agent directly flows into the liquid storage tank through the liquid inlet pipe and directly flows out of the liquid storage tank through the liquid outlet pipe. In order to avoid overload or material shortage of the liquid storage tank, the three-proofing agent in the liquid storage tank is too much in overload, so that the three-proofing agent cannot shake, otherwise, the three-proofing agent overflows the liquid storage tank; the lack of the material is that the three-proofing agent in the liquid storage box is too little or not, the three-proofing agent input from the liquid inlet pipe impacts the bottom of the liquid storage box and then splashes, so that the three-proofing agent wraps the air and then falls back, and new bubbles are doped into the three-proofing agent. In order to know the amount of the three-proofing agent of the liquid storage tank, a liquid level meter is arranged in the liquid storage tank and is positioned at the top of the liquid storage cavity. The level gauge is used for detecting the liquid level height, and this technical scheme only responds to minimum liquid level and highest liquid level, means that the volume of the three proofings agent of liquid reserve tank reaches the maximum value when the level gauge detects the highest liquid level, can not be many more, means that the volume of the three proofings agent of liquid reserve tank reaches the minimum value when the level gauge detects minimum liquid level, can not be few more.
