Description
Technical field
The present invention relates to a kind of bubble trap, especially in the narrow gap bubble trap of line style.
Background technology
In current lithium battery painting process, because coating fluid needs to stir, and coating needs pressure, easily produces gas
Bubble, and bubble is not of uniform size, when coating head is coated with, bubble can rupture when being sprayed from coating head, cause coating fluid to fly
Splash, image coating quality, waste coating fluid and coating pole plate.
Now defoamed using standing a period of time after stirring, time of repose needs more than 2~3 hours, and can only go
Except air pocket, cause to be coated with cycle length, image production efficiency.
As Chinese patent CN102313666A discloses a kind of liquid sample bubble removing device, the bubble trap in tank body by setting
Airway tube is put, inside of a large amount of bubbles along airway tube rises, and accumulation, rupture, gas then pass through row on fluid sample surface
Gas port is discharged；A small amount of bubble in the outer liquid of airway tube moves upwards under buoyancy, is gathered on fluid sample surface, be broken
Split, gas is then discharged by exhaust outlet；So fluid sample exists in bubble trap and defoamed twice, puies forward de-bubble significant effect
It is high.De-bubble is to reduce image of the bubble to fluid analysis, whole system no pressure, do not apply to the coating system with pressure
System.
