A still relates to a still used for distillation in chemical production.Depending on the boiling point of the fraction, the distillation can be completed by vaporizing the fraction needed for heating and collecting it by condensation.It is mainly designed to solve the problem of discontinuous maintenance and cleaning when the material contains solid and high boiling point in the production process of the existing distillation kettle.It includes distillation kettle shell, is on the head, above the distillation kettle shell gas exit is sealing head, the head below the defoaming machine, below the defoaming device for the storage room, storage room upside have feeding mouth, indoor evaporator, still lower for solid substance and settlement of high boiling point material room, indoor set in subsidence mixer, blender are connected to the external motor shaft through the shaft seal, still set a solid material and high boiling point at the bottom of the discharge.The advantage is that the solid and high boiling point material can be discharged at any time, without intermittent maintenance and cleaning, to ensure continuous production.
