Distillation kettle with steam recovery mechanism

According to the distillation still with the steam recovery mechanism, the outer wall of the distillation still is sleeved with the sealed heat preservation shell, the vacuum layer is formed between the inner wall of the heat preservation shell and the outer wall of the distillation still, and the heat loss of the distillation still is prevented according to the vacuum heat insulation principle; the heat preservation effect of the distillation kettle is improved; meanwhile, the waste heat recovery efficiency can be effectively improved. The installation position of the stirring shaft of the distillation kettle is adjusted to the bottom, the problem of insufficient steam collection is reduced, steam generated by the distillation kettle flows into the inclined pipe through the arranged condensation sleeve, and the steam is condensed into liquid drops after passing through the condensation sleeve in the inclined pipe by utilizing the condensation sleeve, so that the liquid drops are condensed into the distillati
