Defoaming device for outer wall surface water-based paint production

Abstract

The invention discloses a defoaming device for outer wall surface water-based paint production, the defoaming device comprises a dispersing tank and a base, the dispersing tank is fixedly mounted on the top surface of the base, a thinning tank is mounted on one side of the dispersing tank, and a coupling is fixedly mounted at the center of the top surface of the dispersing tank. The defoaming device has the beneficial effects that the thinning tank, the rotating pipe, the upper branch pipe and the lower branch pipe are adopted, a defoaming agent enters the rotating pipe from the conveying pipe and flows into the upper branch pipe and the lower branch pipe, the defoaming agent flowing into the upper branch pipe is sprayed above mixed liquid through the spray head, so that foam on the top surface of the mixed liquid is eliminated, meanwhile, the defoaming agent flowing into the lower branch pipe flows out of the leakage hole, and the defoaming effect is good. The defoaming agent is dispersed into the mixed liquid, so that foams in the mixed liquid can be conveniently eliminated during stirring and dispersing, the defoaming agent is uniformly sprayed and put from the inside and the outside of the mixed liquid, the defoaming agent is more uniformly contacted with the mixed liquid, the reaction is quicker, the effect of uniformly putting the defoaming agent for quickly defoaming is achieved, and the defoaming efficiency is further remarkably improved.

Description

technical field [0001] The invention relates to the technical field of exterior wall coatings, in particular to a defoaming device for the production of exterior wall water-based coatings. Background technique [0002] In the preparation process of water-based coatings for exterior walls, it is first necessary to put water, dispersants, preservatives and other liquids together with the slurry into the dispersion tank for stirring and dispersion. The defoamer is put inside to reduce the foam, but the traditional defoamer is relatively viscous. If it is directly put into the dispersion tank, it needs a long time and a lot of stirring to mix the defoamer with the raw materials. Even, more foam will still be produced. At the same time, if the defoamer is not diluted in time, it is easy to cause stratification, which affects the defoaming efficiency. Further improvements can be made. At the same time, the traditional dispersion tube uses Single dispersing head, the dispersing ef...

[0002] In the preparation process of water-based coatings for exterior walls, it is first necessary to put water, dispersants, preservatives and other liquids together with the slurry into the dispersion tank for stirring and dispersion. The defoamer is put inside to reduce the foam, but the traditional defoamer is relatively viscous. If it is directly put into the dispersion tank, it needs a long time and a lot of stirring to mix the defoamer with the raw materials. Even, more foam will still be produced. At the same time, if the defoamer is not diluted in time, it is easy to cause stratification, which affects the defoaming efficiency. Further improvements can be made. At the same time, the traditional dispersion tube uses Single dispersing head, the dispersing efficiency is not high, which affects the production efficiency, and further improvement can be made. In addition, air is needed in the process of foam formation, and the traditional dispersion tank is filled with air, which is conducive to foam formation and not conducive to defoaming. Further improvements can also be made
