[0002] Resin paint refers to a type of coating that uses high molecular resins made by self-polymerization or copolymerization of ethylene derivative monomers containing double bonds as the main film-forming substance. During the preparation of resin paint, a large amount of foam is generated, and the foam needs to be eliminated during stirring.

The top of the defoaming box is provided with a first top cover, and a slow-speed motor is provided at the bottom of the first top cover. In this invention, the slow-speed motor drives the stirring rod and stirring blade to gently stir the acrylic resin paint mixture inside the defoaming box to eliminate bubbles. The cooling is achieved by circulating condensate water inside the circulating condenser pipe to cool the defoamed acrylic resin paint inside the defoaming box.

[0004] In the preparation of resin paint, defoaming is usually achieved by adding defoaming agents. However, using defoaming agents can alter the composition of the paint or require stopping the machine for separation to remove foam, which affects the mixing and molding efficiency.

[0028] A rotary motor 4 is installed at the bottom of the mixing tank 2. The output shaft of the rotary motor 4 passes through the bottom of the mixing tank 2, and a rotating tube 15 is vertically installed on the output shaft of the rotary motor 4.

[0029] The rotating tube 15 has a vertical sliding hole inside, and a movable plate 17 is slidably arranged inside the rotating tube 15. A connecting rod 16 is fixed on the outer surface of the movable plate 17. A first buoyancy ring 18 is fitted on the outer side of the rotating tube 15. The first buoyancy ring 18 is fixed on the connecting rod 16, and the connecting rod 16 is slidably arranged in the sliding hole.

[0030] The top of the movable plate 17 is connected to a second sliding air pipe 9, and air nozzles 19 are connected and installed on both sides of the bottom of the second sliding air pipe 9.

[0031] A scraper 22 is connected to the outer side of the first buoyancy ring 18, and a second buoyancy ring 20 is slidably disposed inside the protective shell 1. The scraper 22 is connected to the second buoyancy ring 20, and the first buoyancy ring 18 and the second buoyancy ring 20 are arranged parallel to each other.

[0032] A rotating ring 21 is rotatably mounted on the top side of the second buoyancy ring 20, and a discharge cover 14 is mounted on the top side of the rotating ring 21. The bottom port of the discharge cover 14 is located between the first buoyancy ring 18 and the second buoyancy ring 20.

[0033] The protective housing 1 has a rod hole on its top side, and the top of the second sliding air pipe 9 passes through the rod hole in the middle of the protective housing 1. The discharge cover 14 is connected to a first sliding air pipe 8, and the top of the first sliding air pipe 8 passes through the rod hole on the side of the protective housing 1.

[0034] A feed hopper 11 is installed on the top of the mixing tank 2, and an air intake fan 12 is installed on the top of the mixing tank 2. The air intake fan 12 is connected to the second sliding air pipe 9 through a second connecting hose 10. Air intake is achieved through the second connecting hose 10, and the air is delivered to the air nozzle 19 through the second sliding air pipe 9. Since the second connecting hose 10 and the second sliding air pipe 9 are rotatably connected, when the rotating pipe 15 rotates, it can drive the rotating plate 17 to rotate, which can realize the synchronous rotation of the first buoyancy ring 18 and the rotating ring 21. When the air nozzle 19 rotates synchronously with the rotating pipe 15, it can drive the air nozzle 19 to rotate. When the air nozzle 19 sprays air, it can blow the bubbles from the middle position to the side. With the synchronous rotation of the first buoyancy ring 18 and the second buoyancy ring 20, and with the cooperation of the scraper 22, the bubbles can be pushed to the inner side of the second buoyancy ring 20, which can realize the pushing of foam for subsequent pumping.

[0035] An air pump 6 is installed on the top side of the protective shell 1. The air inlet of the air pump 6 is connected to the first sliding air pipe 8 through a first connecting hose 7. A guide bucket 3 is installed on the outside of the mixing tank 2. The output port of the air pump 6 is connected to the top opening of the guide bucket 3 through a hose. During operation, under the action of the air pump 6, the air bubbles can be extracted and discharged in cooperation with the first connecting hose 7, the first sliding air pipe 8 and the discharge hood 14. Since the discharge hood 14 is installed on the rotating ring 21 and the rotating ring 21 is rotatably installed on the top side of the second buoyancy ring 20, the position of the discharge hood 14 does not move. It only sucks and discharges the foam blown by the swing. The sucked and discharged foam is transported to the guide bucket 3 by the air pump 6 to achieve centralized processing of foam.

[0036] The bottom of the protective shell 1 is connected to a discharge pipe 5, and the bottom of the guide barrel 3 is connected to a drain pipe. Both the discharge pipe 5 and the drain pipe are equipped with control valves, which can cooperate to discharge the material after defoaming.

[0037] Working principle: When mixing materials, materials are fed into the protective shell 1 through the feed hopper 11. After the materials are fed, the heating wire 13 is energized to adjust the temperature inside the protective shell 1, thereby achieving the mixing of materials.

[0038] During material mixing, the rotary motor 4 drives the rotating tube 15 to rotate, and with the cooperation of the stirring frame 23, the material can be stirred and mixed.

[0039] Under the action of stirring and mixing of materials, a large number of bubbles are easily generated. Under the buoyancy of the paint, the first buoyancy ring 18 and the second buoyancy ring 20 can float on the surface of the paint.

[0040] Under the buoyancy of the paint, the first sliding air pipe 8 and the second sliding air pipe 9 can be lifted and slid upwards.

[0041] By operating the air intake fan 12, air can be intake through the second connecting hose 10 and delivered to the air nozzle 19 through the second sliding air pipe 9. Since the second connecting hose 10 and the second sliding air pipe 9 are rotatably connected, when the rotating pipe 15 rotates, it can drive the rotating plate 17 to rotate, which can realize the synchronous rotation of the first buoyancy ring 18 and the rotating ring 21. When the air nozzle 19 rotates synchronously with the rotating pipe 15, it can drive the air nozzle 19 to rotate. By intake, when the air nozzle 19 sprays air, it can blow the bubbles from the middle position to the side.

[0042] With the synchronous rotation of the first buoyancy ring 18 and the second buoyancy ring 20, and with the assistance of the scraper 22, the air bubble can be pushed to the inside of the second buoyancy ring 20.

[0043] Under the action of the air pump 6, the air bubbles can be extracted and discharged in cooperation with the first connecting hose 7, the first sliding air pipe 8 and the discharge hood 14. Since the discharge hood 14 is installed on the rotating ring 21 and the rotating ring 21 is rotatably installed on the top side of the second buoyancy ring 20, the position of the discharge hood 14 does not move. It only sucks and discharges the foam blown by the swing. The sucked and discharged foam is transported to the guide bucket 3 by the operation of the air pump 6 to concentrate the foam. The foam is defoamed by automatic dissolution. The foam generated by the mixing is transferred and processed in a short time to ensure the effect of the mixed material, reduce the interference of foam on the material and improve the quality of the mixing.
