Ultralow-temperature cryogenic reaction kettle with good heat insulation effect

The utility model discloses an ultralow-temperature cryogenic reaction kettle with a good heat insulation effect. The ultralow-temperature cryogenic reaction kettle comprises a kettle body, a power mechanism is arranged at the upper end of the kettle body, a driving rod is arranged on the power mechanism, a transmission mechanism is arranged at the lower end of the driving rod, and a refrigeration mechanism is arranged on one side of the kettle body. The thermal insulation effect of the cryogenic reaction kettle can be improved through the aerogel felt layer, the temperature in the cryogenic reaction kettle is prevented from being influenced by the outside, and the loss of the temperature in the cryogenic reaction kettle is avoided, so that the chemical reaction effect of materials in the cryogenic reaction kettle can be improved, and meanwhile, when the materials are cooled, the materials are prevented from being damaged. According to the cryogenic reaction kettle, materials in the cryogenic reaction kettle
