[0002] An evaporator is an object that converts liquid substances into gaseous substances. It is mainly composed of a heating chamber and an evaporation chamber. The heating chamber provides the liquid with the heat required for evaporation to promote boiling and vaporization of the liquid, and the evaporation chamber completely separates the gas and liquid phases. It is widely used in chemical industry, light industry and other departments. For example, an energy-saving evaporator (public announcement number CN214714398U) disclosed in the China Patent Network, when evaporating the liquid, uses a driving member to drive the rotating shaft to rotate around its own axis, thereby driving the electric heating rod to rotate, heating different positions of the evaporation tank body, and synchronously controlling the rotation speed of the driving motor to adjust its centrifugal force, so that the electric heating rod slides horizontally, thereby synchronously heating different positions of the liquid, so that the liquid in the evaporation tank body is heated evenly.

[0003] However, there are still some shortcomings in the evaporator structure adopted by the above-mentioned public patent and the existing market: the existing method of using a driving member to drive the electric heating rod to rotate horizontally to fully contact and heat the liquid can only heat the liquid in a limited direction, and cannot fully and dynamically heat the liquid in real time, resulting in insufficient uniformity of heat transfer to the liquid and insufficient efficiency of heating and evaporation. To this end, those skilled in the art provide an evaporator structure with uniform heat transfer to solve the problems raised in the above background technology. Utility Model Content

[0027] A braking mechanism for driving the transmission shaft 13 and the lifting screw 8 is provided at the bottom of the tank body of the evaporator 1.

The differential pulley A15 is connected to the differential pulley B16 through the transmission belt 7. By controlling the transmission motor 6 as a driving source, under the transmission combination of the differential pulley A15, the transmission belt 7, and the differential pulley B16, the combined differential speed of the transmission shaft 13 and the lifting screw 8 is driven to rotate synchronously, and the corresponding components are driven to operate, so as to improve the heating and evaporation efficiency of the liquid.

[0028] The bottom of the chamber of the evaporator 1 is rotatably connected to a transmission shaft 13, and a stirring paddle 14 is provided at the top of the shaft of the transmission shaft 13.
