The input end of the first water pump 6 is fixedly connected to the end of the water suction pipe 5, and the output end of the first water pump 6 is fixedly connected to a first water delivery pipe 7. A first electric regulating valve 8 is fixedly installed on the body of the first water delivery pipe 7. Specifically, when the first water pump 6 is running, it can draw the cooling water in the cold water tank 2 out through the water suction pipe 5 and then deliver it through the first water delivery pipe 7. The cooling water flow rate can be controlled by the first electric regulating valve 8.

[0024] The cooling assembly includes a first water inlet pipe 9, which is fixedly connected to the bottom side of the reaction tank 1. The outer end of the first water inlet pipe 9 is fixedly connected to the top end of the first water supply pipe 7.

Specifically, cooling water can be pumped into the spiral cooling pipe 10 through the first water supply pipe 7 and the first water inlet pipe 9, and then pumped out through the first water outlet pipe 11, thereby cooling the inside of the reaction tank 2.

[0025] The cooling assembly also includes a cooling water jacket 12, which is fixed to the side of the reaction tank 1. A second water inlet pipe 13 is fixedly connected to the bottom of the cooling water jacket 12, and a water inlet branch pipe 14 is fixedly connected to the end of the second water inlet pipe 13.

[0026] The heat exchange assembly includes a support 17, which is fixed to one side of the reaction vessel 1. A first heat exchanger 18 is fixed to the top of the support 17. It should be noted that the heat exchanger is a technology known to those skilled in the art.

[0030] The usage process of this utility model is as follows: When the polyurethane waterproof coating is processed in the reaction tank 1, the operator can control the operation of the first water pump 6. When the first water pump 6 is running, the cooling water in the cold water tank 2 can be drawn out through the water pumping pipe 5 and then transported through the first water supply pipe 7. The flow rate of the cooling water can be controlled by the first electric regulating valve 8. The cooling water can be pumped into the spiral cooling pipe 10 through the first water supply pipe 7 and the first water inlet pipe 9, and then pumped out through the first water outlet pipe 11, thereby cooling the inside of the reaction tank 2. The cooling water can also be pumped into the cooling water jacket 12 through the first water inlet pipe 9 and the water inlet branch pipe 14, and then pumped out through the second water outlet pipe 15 and the water outlet branch pipe 16, thereby cooling the outside of the reaction tank 2. This can effectively achieve simultaneous cooling of the inside and outside of the reaction tank 1, greatly improving the cooling efficiency of the polyurethane waterproof coating.

[0031] The cooling water that has been cooled both inside and outside the reactor 1 can enter the first heat exchanger 18 through the first outlet pipe 11. Then, it can exchange heat with the second heat exchanger 20 through the first heat exchanger 18 to cool down. The cooled water can then be transported to the buffer tank 22 through the second water supply pipe 21. When the second water pump 23 is running, the cooled water can be pumped back into the cold water tank 2 through the third water supply pipe 24 and the return water pipe 4, thus achieving a good cooling cycle function.
