DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following specifically describes the specific embodiments of the utility model with reference to the drawings.

[0018] Embodiment:

[0019] Combined with the drawings, the specific embodiment of a cooling device for an epoxy resin reactor of the utility model is shown. As Figure 1 , it mainly includes a water tank 2 installed at the lower part of the reactor body 1. The water tank 2 is attached to the outer wall of the reactor body 1. The bottom of the water tank 2 is connected with a cold water inlet pipe 201, a hot water inlet pipe 202, and an outlet pipe 203. A temperature sensor 204 and a water level sensor 205 are also arranged in the water tank 2. AsFigure 2 as shown

[0020] Combined with Figures 1 to 3 , an O-shaped tube 3 is provided in the water tank 2, and the O-shaped tube 3 is connected to the liquid nitrogen tank 5 through a connecting pipe 4. A plurality of cold pipes 6 are connected to the O-shaped tube 3, and the plurality of cold pipes 6 are evenly distributed on the O-shaped tube 3 at equal angles. Each cold pipe 6 passes through the top of the water tank 2 and is connected to a cooling plate 7. A plurality of cooling plates 7 are evenly arranged around the reaction kettle body 1, and the cooling plates 7 extend along the height of the reaction kettle body 1 to the upper part of the reaction kettle body 1.

[0021] Combined with Figure 4 and Figure 5 , each cooling plate 7 includes a lower connecting block 701 and an upper flow dividing plate 702. The inside of the connecting block 701 is a hollow structure, and the cold pipe 6 is connected to the flow dividing plate 702 through the connecting block 701. The flow dividing plate 702 is divided into an inner chamber 702a and an outer chamber 702b by a partition plate 703. The bottoms of the inner chamber 702a and the outer chamber 702b are both open and communicate with the top of the connecting block 701. The top of the inner chamber 702a is closed, and a plurality of first through holes 704 communicating with the inner chamber 702a are opened on the inner side wall of the flow dividing plate 702. The top of the outer chamber 702b is open and connected to a cooling ring 8. The cooling ring 8 is arranged on the upper part of the reaction kettle body 1, and a plurality of second through holes are opened on the inner side wall of the cooling ring 8.

[0022] The inner side surfaces of the connecting block 701 and the flow dividing plate 702 of the cooling plate 7 are both arc surfaces, which can better blow the cold air to the surface of the reaction kettle body 1 to cool it.

[0023] When the cooling device of the present utility model works specifically, the heat generated by the reaction kettle body 1 can be used to heat the water tank 2, which plays a certain role in cooling the reaction kettle body 1.

Cooperating with the cold water inlet pipe 201, the hot water inlet pipe 202, and the outlet pipe 203 at the bottom can adjust the temperature and the water level of the internal water to be maintained within a preset range, avoiding the water temperature being too high or too low, which affects the conversion of liquid nitrogen. The liquid nitrogen in the liquid nitrogen tank 5 can enter the O-shaped tube 3 through the connecting pipe 4. Under the action of the temperature difference, the liquid nitrogen is converted into nitrogen gas and is respectively distributed to each cooling plate 7 through a plurality of cold pipes 6. The cold air first enters the lower connecting block 701, and then enters the flow dividing plate 702 and flows in two paths. One path enters the inner chamber 702a and blows the cold air directly to the outer wall of the reaction kettle body 1 through the first through holes 704. The other path enters the outer chamber 702b and converges to the cooling ring 8, and then sends the cold air to the top of the reaction kettle body 1 through the second through holes. This part of the cold air will continue to move downward along the reaction kettle body 1, achieving the effect of sufficient cooling. Using the cooling device of the present utility model can realize the rapid cooling of the reaction kettle body, with good cooling effect, which is beneficial to improving the production efficiency and prolonging the service life of the reaction kettle.
