Since the inclination directions of the first stirring blade and the second stirring blade are opposite, the styrene-butadiene latex under the tank is Under the action of the first stirring blade, it moves upward along the side wall, and the styrene-butadiene latex above the tank moves downward along the extension direction of the rotating shaft under the action of the first stirring blade, forming a cycle; during the circulation of the styrene-butadiene latex , the water in the cooling pipe cools the styrene-butadiene latex, and after the water in the cooling pipe becomes hot, the styrene-butadiene latex is cooled again after being cooled by the cooling water tower; the styrene-butadiene latex is cooled by the first stirring blade and the second stirring blade Circular stirring, so that the styrene-butadiene latex in the whole tank moves, and the cooling effect of the water in the cooling pipe on the styrene-butadiene latex is improved.

The utility model is further configured as follows: the connection between the water outlet pipe and the cooling pipe is located above the tank body, and the connection between the water inlet pipe and the cooling pipe is located below the tank body.

By adopting the above technical scheme, the water in the cooling pipe enters from below, and the water in the cooling pipe flows out from above; the water in the cooling pipe gradually becomes hot during the flow process, so the temperature of the water below the cooling pipe is higher than that of the cooling pipe. The temperature of the water above is low. Due to the accumulation of styrene-butadiene latex under the tank body, the temperature is higher than that of the styrene-butadiene latex above the tank body, thereby improving the cooling efficiency of the styrene-butadiene latex.

The utility model is further set as: the side wall of the tank body is provided with an isolation groove along its circumference.

By adopting the above technical scheme, the outer wall of the tank will heat up under the action of direct sunlight, and the outer wall of the tank is isolated through the isolation groove, thereby reducing the probability of the temperature transfer of the outer wall of the tank to the inside of the tank.

The cooling water tower 3 has the effect of cooling the hot water. The water enters the cooling water tower 3 from the water inlet pipe 5 for cooling, and then the water enters the cooling pipe 4 from the water outlet pipe 6 to cool the styrene-butadiene latex inside the tank body 2 .

As shown in Figures 1 and 2: a rotating shaft 8 is installed in the tank body 2, and a motor 9 for driving the rotating shaft 8 is fixedly arranged below the tank body 2, and the output shaft of the motor 9 is fixedly connected with the rotating shaft 8. A plurality of connecting rods 10 are fixedly arranged on the rotating shaft 8, a first stirring blade 11 which is arranged obliquely is fixedly arranged on the connecting rod 10, a second stirring blade 12 which is arranged obliquely is fixedly arranged on the rotating shaft 8, and the second stirring blade 12 is fixedly arranged on the rotating shaft 8. The direction of inclination is opposite to the direction of inclination of the first stirring blade 11 . The second stirring blade 12 is located above the connecting rod 10 . The motor 9 drives the rotating shaft 8 to rotate, so that the first stirring blade 11 and the second stirring blade 12 rotate at the same time. Since the inclination directions of the first stirring blade 11 and the second stirring blade 12 are opposite, the styrene-butadiene latex under the tank body 2 Under the action of the first stirring blade 11, it moves upward along the side wall, and the styrene-butadiene latex above the tank body 2 moves downward along the extension direction of the rotating shaft 8 under the action of the first stirring blade 11, forming a cycle.

An abutting piece 13 abutting against the inner wall of the tank body 2 is fixedly arranged on the first stirring blade 11 . The side of the abutting piece 13 far away from the inner wall of the tank body 2 is arranged on an inclined plane. When the motor 9 was working, the abutting piece 13 scraped off the styrene-butadiene latex on the side wall of the tank body 2 .

The side wall of the tank body 2 is provided with an isolation groove 14 along its circumference. An isolation pipe 18 is arranged inside the isolation tank 14 , and a cooling water tank 15 connected to the isolation pipe 18 is arranged outside the tank body 2 , and a second water pump 16 is arranged on the isolation pipe 18 . The isolation tube 18 is arranged in a spiral shape around the axis of the tank body 2 in the isolation groove 14 . A light-reflecting layer 17 is arranged on the outside of the tank body 2, and the light-reflecting layer 17 is a reflective heat-insulating paint. Water enters the isolation pipe 18 from the cooling water tank 15 to cool the isolation tank 14 , thereby reducing the amount of heat transfer from the outer wall of the tank body 2 to the inside of the tank body 2 .

Working principle: The motor 9 works, so that the first stirring blade 11 and the second stirring blade 12 rotate at the same time, so that the styrene-butadiene latex under the tank body 2 moves upward along the side wall under the action of the first stirring blade 11, and the tank The styrene-butadiene latex above the body 2 moves downward along the extension direction of the rotating shaft 8 under the action of the first stirring blade 11 , and the styrene-butadiene latex circulates in the tank body 2 .

In the process of circulating the styrene-butadiene latex in the tank body 2, the water in the cooling pipe 4 cools the styrene-butadiene latex, and the water in the cooling pipe 4 becomes hot during the cooling of the styrene-butadiene latex, and the water in the cooling pipe 4 passes through The water outlet pipe 6 enters the cooling water tower 3 for cooling, and then the water enters the cooling pipe 4 through the water inlet pipe 5 to continue cooling the styrene-butadiene latex. Good cooling effect.

When the temperature in the isolation tank 14 is low, it is not necessary to import the water in the cooling water tank 15 into the isolation pipe 18.
