Description

Technical Field

[0001] The utility model relates to the technical field of stirring kettles, in particular to an aqueous paint stirring kettle with a defoaming function. Background Technique

[0002] Waterborne coatings refer to coatings formulated with post-emulsified emulsions. Solvent-based resins are dissolved in organic solvents, and then with the help of emulsifiers, the resins are dispersed in water by strong mechanical stirring to form emulsions, called post-emulsified emulsions. The coatings made can be diluted with water during construction. Water-dispersed coatings mainly refer to coatings formulated with synthetic resin emulsions as film-forming substances. When making them, they need to be placed in a stirring kettle for stirring. After retrieval, a patent with the Chinese patent authorization announcement number CN219898127U discloses a reaction device for producing waterborne coatings, including a reaction kettle, a stirring mechanism, a first defoaming mechanism, and a second defoaming mechanism. The stirring mechanism is located inside the reaction kettle, the first defoaming mechanism is located inside the reaction kettle, the second defoaming mechanism is located at the upper end of the reaction kettle. The first defoaming mechanism includes a connecting plate, a vibrating rod, fastening bolts, and fastening nuts. The connecting plate is installed at the outer end of the stirring mechanism, and the connecting plates are symmetrically distributed. In this reaction device for producing waterborne coatings, by setting the first defoaming mechanism, when using the stirring mechanism to stir the waterborne coatings, the stirring shaft can drive the vibrating rod to rotate at the same time. The vibrating rod can thus vibrate the waterborne coatings more comprehensively to eliminate the bubbles inside them, and by unscrewing the fastening bolts and fastening nuts, the final coating effect of the waterborne coatings can be ensured. However, after the stirring kettle finishes stirring the waterborne coatings, even if the coatings attached to the inner wall of the stirring kettle can be scraped off by a scraper, the stirred coatings inside still cannot be discharged, thus making it inconvenient to clean the inside of the stirring kettle.

[0022] Embodiment 2

[0023] In order to improve the stirring efficiency of the aqueous paint inside, in this embodiment, as Figures 2-5 shown, a first rotating motor 7 and a second rotating motor 8 are fixedly installed at the upper end of the cover plate 2. A rotating rod 17 is rotatably connected inside the bottom surface of the cover plate 2. The output shaft of the first rotating motor 7 is fixedly connected to the upper end of the rotating rod 17 through the inside of the cover plate 2. A rotating pipe 13 is slidably sleeved on the outer part of the upper end of the rotating rod 17. A first gear 20 is fixedly sleeved at the upper end of the rotating pipe 13. A second gear 21 is rotatably connected to the bottom surface of the cover plate 2. The output shaft of the second rotating motor 8 is fixedly connected to the upper end of the second gear 21 through the inside of the cover plate 2.

The first rotating motor 7 rotates the rotating rod 17, and the second rotating motor 8 rotates the second gear 21, so that the first gear 20 can be rotated. The first gear 20 can rotate the rotating pipe 13, enabling the second stirring rod 17 and the first stirring rod 14 to rotate in opposite directions for stirring work, and enhancing the stirring efficiency.

[0024] Embodiment 3

[0025] In order to facilitate the elimination of bubbles in the water-based paint stirred inside the barrel body 1, in this embodiment, as Figures 1-2 shown, an air extraction pump 9 is fixedly installed at the upper end of the cover plate 2. The air extraction end of the air extraction pump 9 is connected to the inside of the barrel body 1 through a fixedly connected air extraction pipe. A liquid injection pipe 6 is fixedly installed at the upper end of the cover plate 2. The liquid injection pipe 6 is arranged on the right side of the first gear 20 and the second gear 21. When the stirring work is carried out, by turning on the air extraction pump 9, the gas scattered by the stirring inside the barrel body 1 can be conveniently extracted, and the generation of bubbles inside can be further reduced.

[0026] It should be noted that in this embodiment, when using a water-based paint stirring kettle with a defoaming function, as Figures 1-5 shown, when stirring the water-based paint, the cover plate 2 is made to fit with the top surface of the barrel body 1 by closing the cylinder 4 mode. The paint to be stirred is injected into the inside of the barrel body 1 through the liquid injection pipe 6. Subsequently, the first rotating motor 7 and the second rotating motor 8 are turned on. The first rotating motor 7 makes the rotating rod 17 rotate, and the second rotating motor 8 makes the second gear 21 rotate, so that the first gear 20 can be rotated. The first gear 20 can make the rotating pipe 13 rotate, and the second stirring rod 17 and the first stirring rod 14 can rotate in the opposite direction to carry out the stirring work, which can enhance the stirring efficiency. While stirring, an antifoaming agent is injected into the inside of the barrel body 1 through the liquid injection pipe 6, and the air extraction pump 9 is turned on. The antifoaming agent can improve the elimination of bubbles inside the water-based paint, and the air pump 9 can conveniently extract the gas scattered by the stirring inside the barrel body 1, which can further reduce the generation of bubbles inside. After the stirring is completed, the valve 11 is opened to discharge the water-based paint inside, and then the cylinder 4 is opened to make the cover plate 2 move upward until the conical pipe 10 moves out of the inside of the barrel body 1. Subsequently, the inside of the barrel body 1 can be conveniently cleaned.
