[0021] Please refer to Figs. 1-3 The utility model provides a technical scheme: a color paste cooling constant temperature device, comprising:

[0022] Box 1, the upper end of box 1 is provided with inlet 11, inlet 11 is fixedly connected with box 1, and guide pipe 12 is arranged below inlet 11, and guide pipe 12 is located inside box 1;

[0026] Liquid nitrogen cooling mechanism 5, liquid nitrogen cooling mechanism 5 is located on the right side of box 1, and liquid nitrogen cooling mechanism 5 can play a significant compensation cooling effect.

[0027] Cold water circulating mechanism 4 includes cooling water tank 41 located on the left side of support 2, water inlet pipe 42 is fixedly connected above cooling water tank 41, water outlet pipe 43 is arranged on the side close to support 2 of water inlet pipe 42, water outlet pipe 43 is fixedly connected with cooling water tank 41, circulating water pump 44 is communicated in the middle of water inlet pipe 42, condensing inner tube 45 is fixedly connected at the end of water inlet pipe 42 away from cooling water tank 41, and the end of condensing inner tube 45 away from water inlet pipe 42 is fixedly connected with water outlet pipe 43.

[0028] The liquid nitrogen cooling mechanism 5 comprises a liquid nitrogen tank 51 located on the right side of the box body 1, and a discharge pipe 52 is fixedly connected above the liquid nitrogen tank 51, and an air inlet 53 is fixedly connected to the end of the discharge pipe 52 away from the liquid nitrogen tank 51, and a gas valve 54 is flange-connected to the end of the discharge pipe 52 close to the liquid nitrogen tank 51.

[0029] The outer layer of the condensing inner tube 45 is provided with a protective sleeve 55 located inside the box body 1, and the condensing inner tube 45 and the protective sleeve 55 are provided with sealing rubber rings 56 at the gaps at both ends, and the protective sleeve 55 is provided with an air outlet pipe 57 at the upper position of the middle segment, and the air outlet pipe 57 is fixedly connected with an air outlet 58 at the end away from the protective sleeve 55, and the protective sleeve 55 is provided with an air inlet pipe 59 at the lower position of the middle segment, and the air inlet pipe 59 is fixedly connected with the air inlet 53 at the end away from the protective sleeve 55.

[0030] The bottom side of the box body 1 is provided with a discharge outlet 13, and the discharge outlet 13 is fixedly connected with a discharge pipe 14, and a temperature sensor 15 is fixedly connected above the discharge pipe 14.

[0031] The data input end of the controller 3 is electrically connected with the temperature sensor 15, and the data output end of the controller 3 is electrically connected with the gas valve 54.

[0032] The color paste is introduced into the box body 1 through the inlet 11, at this time, the color paste is in a high-temperature state, and the cold water circulating mechanism 4 drives the circulating water pump 44 to draw cold water from the cooling water tank 41 and send it into the condensing inner tube 45 through the water inlet pipe 42, and the cold water continuously flows in the condensing inner tube 45, which effectively absorbs and removes the heat of the color paste in the box body 1 by using the convection heat exchange mode, thereby achieving the cooling effect, and the cold water after heat exchange flows out from the water outlet pipe 43 and returns to the cooling water tank 41 for the next cycle, which not only ensures that the color paste can be uniformly and effectively cooled, but also realizes the recycling of the cold water and improves the energy utilization efficiency.

[0033] The color paste is introduced into the discharge pipe 14 through the discharge port 13, and a high-precision temperature sensor 15 is installed inside the discharge pipe 14, which is closely connected with the controller 3 and can measure the temperature of the color paste being cooled in real time. If the detected temperature is higher than the required temperature threshold in the production process, the controller 3 will immediately respond and trigger the air valve 54 device connected thereto. With the smooth opening of the air valve 54, liquid nitrogen is accurately introduced into the discharge pipe 52. In the discharge pipe 52, the liquid nitrogen begins to rapidly vaporize, and this vaporization process is accompanied by a large amount of heat absorption, thereby generating low-temperature gas. These low-temperature gases are then introduced into the protective sleeve 55. Due to the heat absorption characteristics of the vaporization of liquid nitrogen, the ambient temperature around the protective sleeve 55 is significantly reduced, thereby achieving a more efficient cooling effect on the color paste. The vaporized gas is then smoothly discharged outside the box 1 through the gas outlet pipe 57. At the same time, the protective sleeve 55 also plays an important isolating role, effectively separating the cold water in the condensing inner pipe 45 from the color paste in the box 1, thereby ensuring the purity of the color paste and avoiding pollution problems that may be caused by direct contact with cold water.

[0034] In summary, this process not only achieves precise control of the temperature of the color paste, but also further enhances the cooling effect through the heat absorption characteristics of the vaporization of liquid nitrogen, and ensures the purity and safety of the color paste.

[0035] The color paste flows into the discharge pipe 14 through the discharge port 13, and the discharge pipe 14 has a temperature sensor 15 inside. The temperature sensor 15 is connected to the controller 3 and can measure the temperature of the color paste being cooled. If the temperature is higher than the required temperature in the production process, the controller 3 connected to the air valve 54 starts to start, the air valve 54 opens, the liquid nitrogen enters the discharge pipe 52, the liquid nitrogen begins to vaporize, and the vaporized gas quickly enters the protective sleeve 55. Since the vaporization of liquid nitrogen is an endothermic process, the environment around the protective sleeve 55 can be further cooled, thereby strengthening the cooling of the color paste. After that, the vaporized gas flows into the gas outlet pipe 57, and the gas outlet pipe 58 discharges the box 1. In addition, the protective sleeve 55 can also isolate the cold water in the condensing inner pipe 45 from the color paste in the box 1, thereby protecting the color paste from being contaminated by the cold water.
