[0037] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] like Figures 1 to 8 As shown, a cooling storage tank for waterborne acrylic emulsion products includes a storage tank 1 for storing waterborne acrylic emulsion products, a geared motor 2, and a cooling bracket 3. The cooling bracket 3 is installed on the top of the storage tank 1, and a cover plate 4 is installed on the top of the cooling bracket 3. The geared motor 2 is installed on the cover plate 4.

[0039] The cooling bracket 3 includes a circular lower support plate 31, a circular upper support plate 32, and eight internally threaded tubes 33. The internally threaded tubes 33 are welded between the lower support plate 31 and the upper support plate 32. The upper support plate 32 has an upper through hole 321 that communicates with the internally threaded tubes 33, and the lower support plate 31 has a lower through hole 311 that communicates with the internally threaded tubes 33. The lower support plate 31 and the upper support plate 32 are coaxial, and the eight internally threaded tubes 33 are arranged in a circular array with the central axis of the lower support plate 31 as the center.

[0040] The top of the cooling bracket 3 is provided with a dispensing groove 34 for dispensing water-based acrylic emulsion products. Specifically, the dispensing groove 34 is a circular groove on the upper support plate 32.

[0041] The cover plate 4 covers the distribution groove 34, and the cover plate 4 is provided with a feed pipe 41 that communicates with the distribution groove 34.

[0042] The cover plate 4 and the upper support plate 32 are connected by bolts that engage with the internally threaded pipe, and a rubber sealing gasket is sandwiched between the cover plate 4 and the upper support plate 32. The lower support plate 31 and the top of the storage tank are connected by bolts that engage with the internally threaded pipe, and a rubber sealing gasket is sandwiched between the lower support plate 31 and the support plate 32.

[0043] The cooling bracket 3 is equipped with eight cooling pipes 35 that connect the distribution groove 34 to the storage tank 1. The upper and lower ends of the cooling pipes 35 are welded to the upper support plate 32 and the lower support plate 31, respectively. The eight cooling pipes are arranged in a circular array with the central axis of the lower support plate as the center. The cross-section of the cooling pipes is circular. The upper support plate 32 has an upper circular hole 322 that communicates with the cooling pipes 35, and the lower support plate 31 has a lower circular hole 312 that communicates with the cooling pipes 35. Multiple heat sinks 351 are fixed to the outer wall of the cooling pipes 35 and are evenly distributed along the axial direction of the cooling pipes. The heat sinks 351 have an annular tail and are coaxial with the cooling pipes 35. The heat sinks 351 increase the heat exchange area between the cooling pipes 35 and the outside air, thereby improving the heat dissipation efficiency of the cooling pipes 35.

[0044] The storage tank, cooling support 3, and cover plate are all made of stainless steel.

[0045] The produced water-based acrylic emulsion is distributed to various cooling pipes through a distribution tank. After being cooled in the cooling pipes, the water-based acrylic emulsion flows into the storage tank below, reducing the temperature of the water-based acrylic emulsion in the storage tank and reducing the risk of deterioration due to high temperature during storage.

[0046] A rotating shaft 5 is rotatably mounted in the cooling bracket 3. The specific mounting structure is as follows: a bearing mounting seat 313 coaxial with the lower support plate 31 is fixedly connected to the top center of the lower support plate 31. A waterproof sealed bearing 6 is installed in the bearing mounting seat 313. The middle part of the rotating shaft 5 is interference-fitted into the inner ring of the waterproof sealed bearing 6. The power output shaft of the geared motor 2 is connected to the rotating shaft 5 through a coupling 7.

[0047] Four fan blades 8 are mounted on the upper part of the rotating shaft 5 to increase airflow. Each fan blade 8 includes a mounting plate 81 with a fan-shaped cross-section and a rectangular fan blade body 82. The fan blade body 82 is integrally formed with the mounting plate 81 and is perpendicular to the centrifugal side of the mounting plate 81. The mounting plate 81 is mounted on the rotating shaft 5 with screws. When the rotating shaft 5 rotates, it drives the fan blades 8 to rotate, promoting airflow around the cooling pipe and improving the heat dissipation effect of the cooling pipe.

[0048] The lower part of the rotating shaft 5 extends into the storage tank 1 and is fitted with multiple agitators 9. Each agitator 9 includes an annular mounting ring 91 and three agitator blades 92 arranged in a circular array around the central axis of the mounting ring 91. The agitator blades 92 are welded to the outer wall of the mounting ring 91, and the inclination angle of the agitator blades 92 is 30°. The mounting ring 91 is fitted onto the rotating shaft 5 and connected to the rotating shaft 5 with screws. When the rotating shaft 5 rotates, it drives the agitators 9 to rotate, thereby agitating the water-based acrylic emulsion product in the storage tank and preventing the water-based acrylic emulsion product from separating due to prolonged standing.

[0049] A vertically downward-extending discharge pipe 11 is provided at the center of the bottom of the storage tank 1. The discharge pipe 11 is connected to the inside of the storage tank. When in use, a shut-off valve is installed on the discharge pipe 11. When the shut-off valve is opened, the water-based acrylic emulsion product in the storage tank 1 is discharged. When the shut-off valve is closed, the water-based acrylic emulsion product is stored in the storage tank 1. Three support legs 12 are welded to the bottom of the storage tank 1 in a circular array with the central axis of the storage tank as the center.

[0050] The geared motor 2 is a vertical geared motor with a power output shaft speed of 5 revolutions per minute.
