Efficient evaporation and concentration device

The utility model belongs to the technical field of chemical production equipment, and particularly relates to an efficient evaporation and concentration device. In order to solve the technical problem that the efficiency of the conventional normal-pressure evaporation process is low, the technical scheme is as follows: the device comprises an evaporation tank, a communicating pipe, a condensation tank and a controller, and two ends of the communicating pipe are respectively communicated with the evaporation tank and the condensation tank; a feeding pipe is arranged on one side of the top face of the evaporation tank, a stirring device is arranged in the middle of the evaporation tank, a hollow jacket is arranged on the periphery of the lower middle portion of the outer side wall of the evaporation tank in a wrapping mode through a screen ring plate, a discharging pipe is arranged in the middle of the bottom face of the evaporation tank, a drain pipe is arranged in the middle of the bottom face of the jacket,
