[0002] Temperature is an important factor in the chemical reaction. It is shown in various experimental conclusions that the temperature is directly proportional to the speed of the chemical reaction. Therefore, in the production process of the foam fire extinguishing agent, it is necessary to use the reactor to process the foam fire extinguishing agent. Stirring and heating are used to improve the reaction efficiency. After the existing reactor is heated, a large amount of heat will be dissipated through the outer wall of the reactor, resulting in the need to increase the power of the heater to continuously meet the heat required for the reaction, resulting in a waste of electricity and heat.

[0003] The existing patent No. CN112275246B proposes a thermal cycle chemical reaction kettle, including a base, the upper end of the base is fixedly connected with a kettle body and a thermal cycle box, the inside of the kettle body is provided with a liner, the liner and the kettle body The insulation layer is filled in between, and the airflow pipe spirally arranged outside the inner tank is arranged in the said insulation layer, the input end of the airflow pipe is arranged on the side wall of the inner tank, and the output end of the airflow pipe is provided Two, the two output ends are respectively fixedly connected with an upper branch pipe and a lower branch pipe, and the other ends of the upper branch pipe and the lower branch pipe are fixedly connected on the side wall of the thermal cycle box, and a set is arranged between the upper branch pipe and the lower branch pipe There is a valve control mechanism, and a horizontal partition is fixedly connected to the thermal cycle box, and the partition plate divides the thermal cycle box into a cooling chamber and a purification chamber, and the side wall of the cooling chamber is provided with a water inlet pipe and a drain pipe , the side wall of the purification chamber is provided with an exhaust pipe, the upper branch pipe communicates with the purification chamber through the cooling chamber, and the lower branch pipe directly communicates with the purification chamber, which is insulated by wrapping with heat insulating material , but the heat insulation material that can satisfy both heat insulation and strength has the problem of high cost in use. In addition, after the chemical reaction is over, the heat insulation material hinders the cooling of the raw material, and a cooling mechanism is required to cool down, resulting in equipment The use and maintenance costs of the

[0004] The existing patent No. CN107456936A proposes a reaction kettle with a packing device, which has a cylindrical kettle body and a cover body. The kettle body includes an outermost shell, a heating layer inside the shell and an innermost lining. There is a vacuum isolation chamber between the shell and the heating layer, and there is a heating element inside the heating layer, which is used to electrically heat the lining; layer and a corrosion-resistant heat-insulating layer; wherein, the kettle body has an upper opening, and the opening has a first step, and the edge position of the packing layer and the corrosion-resistant heat-insulating layer also constitutes a A matching second step, the packing layer is provided with a plurality of filling ports at the horizontal position of the second step, and the packing ports are connected to the packing device through a packing pipe; the corrosion-resistant heat insulation layer and the packing layer It can be retracted into the cover plate, so that the filling port is connected with the cavity of the kettle body, and the filling port is provided with a sealing ring, which is insulated by adding a heat insulating medium in the kettle body, but its When switching between heat insulation and de-insulation functions, the steps are cumbersome and inefficient, and it is inconvenient to cool down after the chemical reaction is over.
