[0050] In an embodiment, the electric heating structure comprises an electric heating wire, the grid structure 30 comprises a grid mesh arranged in an interlaced manner, and the electric heating wire is arranged in the grid mesh.

[0051] In the embodiment, the electric heating wire has a simple structure, and the complexity of the grid structure is reduced by the electric heating structure including the electric heating wire. Moreover, the heating range of the grid structure is expanded by arranging the electric heating wire in the grid mesh, thereby improving the foam elimination efficiency.

[0052] In an embodiment, the reaction kettle further includes a solenoid valve, and the solenoid valve is electrically connected between the detection device 20 and the electric heating structure.

[0059] An example of the present disclosure provides a reaction kettle for automatically eliminating foam, as shown in Figure 1As shown, the reaction kettle comprises a reaction kettle body 10, a transmitting element 21, a receiving element 22, a grid structure 30, a solenoid valve, a jacket 40, a stirring motor 50, a stirring shaft 60 and a stirring paddle 70. The grid structure 30 comprises staggered grid meshes, and an electric heating wire is arranged in the grid mesh. The transmitting element 21 and the receiving element 22 are arranged on the inner wall of the reaction kettle body 10, the transmitting end of the transmitting element 21 is arranged opposite to the receiving end of the receiving element 22, and the distance between the transmitting element 21 and the bottom of the reaction kettle body 10 is the same as the distance between the receiving element 22 and the bottom of the reaction kettle body 10.

[0060] The working principle of the utility model is described as follows:

[0061] When the height of the foam rises to between the grid structure 30 and the transmitting element 21, the transmitting element 21 emits infrared laser to the receiving element 22, because the medium between the transmitting element 21 and the receiving element 22 is air, the electric signal generated by the receiving element 22 cannot drive the solenoid valve to heat the electric heating wire, and the grid structure 30 only physically punctures the foam to eliminate the foam. When the height of the foam is higher than or equal to the transmitting element 21, the transmitting element 21 emits infrared laser to the receiving element 22, because the medium between the transmitting element 21 and the receiving element 22 includes the foam, the electric signal generated by the receiving element 22 can drive the solenoid valve to heat the electric heating wire, and the grid structure accelerates the elimination of the foam by puncturing and heating. With the elimination of the foam, when the height of the foam drops to between the grid structure 30 and the transmitting element 21, the transmitting element 21 emits infrared laser to the receiving element 22, because the medium between the transmitting element 21 and the receiving element 22 is air, the electric signal generated by the receiving element 22 cannot drive the solenoid valve to heat the electric heating wire, and the electric heating valve automatically closes the heating of the electric heating wire.
