When the defoaming device for preparing the water-based acrylate emulsion works, firstly, a liquid containing barrel 104 storing a defoaming agent is buckled on a top plate 102 in a manual mode, the upper end of a vertical tube 103 is inserted into the liquid containing barrel 104, the defoaming agent flows into the vertical tube 103 through a material passing hole and flows into a reaction barrel 10 along the vertical tube 103, meanwhile, a fixing block 101 is driven to move along an annular track groove through a second electric sliding block 100, the liquid containing barrel 104 and the top plate 102 synchronously move along with the fixing block 101, a stirring rod 14 is driven to rotate at a medium speed through a first motor 12 to stir and mix the water-based acrylate emulsion and the defoaming agent, and the defoaming agent is used for eliminating bubbles generated during preparation.

During the first step, the flat plate 190 makes reciprocating linear motion through the third electric slide block 109, the flat plate 190 drives the teeth 191 to move synchronously, the gear 192 is matched with the teeth 191, the gear 192 drives the rectangular block 106 to rotate in a reciprocating mode through a pin shaft connected with the gear 192, the round rod 107 is driven by the rectangular block 106 to rotate synchronously in a vertical direction, and the round rod 107 can stir and mix the defoaming agent and the water-based acrylate emulsion.

Second step, after waterborne acrylate emulsion preparation, drive solid fixed ring 21 downstream through an electronic slider 24, gu fixed ring 21 drives bubble bucket 20 synchronous motion, remove bubble bucket 20 and drive 18 synchronous motion of axostylus axostyle, shrouding 19 is along with 18 synchronous motion of axostylus axostyle, shrouding 19 breaks away from behind the discharging hole, waterborne acrylate emulsion is by discharging hole inflow in the pipe 16, and along 16 inner chambers of pipe inflow bubble bucket 20 that removes, remaining bubble is broken after touching sharp tooth 17, the liquid that the bubble rupture released still flows into and removes bubble bucket 20.

Thirdly, when a small amount of aqueous acrylate emulsion is left in the reaction barrel 10, the shaft rod 18 drives the sealing plate 19 to continuously move downwards through the first electric slide block 24 until the sealing plate 19 is separated from the circular tube 16, at the moment, the lower end of the reaction barrel 10 is positioned outside the bubble removing barrel 20, the flowing space of the aqueous acrylate emulsion is enlarged, after the aqueous acrylate emulsion basically flows out, the bubble removing barrel 20 is driven to rotate at a high rotating speed through the second motor 22, the aqueous acrylate emulsion is concentrated at the barrel wall of the bubble removing barrel 20 under the action of centrifugal force and flows circumferentially, the aqueous acrylate emulsion falls towards and passes through the screen plate 200 at a high speed, in the process, the residual bubbles are broken, the effect of assisting in removing the bubbles is achieved, and the aqueous acrylate emulsion released by the broken bubbles is immediately fallen towards the barrel wall of the bubble removing barrel 20 by the centrifugal force and flows back into the bubble removing barrel 20.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
