Description

Technical Field

[0001] The utility model relates to the technical field of negative pressure defoaming, in particular to a negative pressure defoaming machine provided with a follow-up defoaming structure. Background Art

[0002] Negative pressure debubbling machine, also known as vacuum debubbling machine, is a device that removes bubbles by reducing the pressure in the liquid. Under vacuum conditions, the bubbles in the liquid will expand, and when they reach a certain size, they will float to the surface. By adjusting the heating and cooling methods, the bubbles can be evaporated from the liquid faster, thereby achieving the debubbling effect. The principle of vacuum debubbling is based on the characteristics of gas diffusion and dissolution. Under a vacuum environment, the diffusion rate of the gas is accelerated, so that the bubbles in the material can diffuse and discharge faster. At the same time, due to the reduced solubility of the gas in a vacuum environment, the gas molecules originally dissolved in the material are gradually released, thereby reducing the formation of bubbles. The combined effect of these two factors enables vacuum debubbling to effectively remove bubbles in the material and improve the density and performance of the material. In the process of using the negative pressure debubbling machine, corresponding parameters need to be set, including time, temperature and vacuum degree. First of all, Place the liquid that needs to be debubbled in a container, then place the container into the negative pressure debubbling machine, and then, by reducing the pressure, gradually reduce the pressure in the container, and gradually extract the bubbles and gas. In this way, after a certain period of time, the bubbles in the liquid can be basically removed. The negative pressure debubbling machine can effectively remove bubbles in the liquid and improve the quality of the liquid. Its operation is relatively simple. You only need to set some basic parameters to start the debubbling program. However, the negative pressure debubbling machine requires a certain equipment cost, and it requires a relatively long processing time, and it is impossible to remove bubbles quickly. This equipment is not suitable for large-scale processing. At the same time, when there are many bubbles in the liquid that needs to be processed, as the bubbles continue to float up, a large number of bubbles will gradually accumulate. Once the natural bursting speed of the bubbles is slower than the generation speed of the bubbles, a large number of bubbles will overflow with a certain amount of liquid to be processed, which is not conducive to the cleaning and maintenance of the negative pressure debubbling machine.

[0034] When in use, first open the closed door 3 on one side of the body 1 and place the material container 6 containing the liquid to be treated on the supporting platform 5, then close the closed door 3 and control the vacuum pump 4 through the operation panel 2 to evacuate the interior of the body 1, so that the bubbles in the liquid to be treated can gradually precipitate and float up;

[0035] When the puncture structure is needed to help the bubbles burst, the rotating rod 7 is rotated and the limiting rod 12 is flipped upward.
