Heating device for low-temperature concentrator

The heating device for the low-temperature concentrator comprises a concentration barrel body, a supporting frame is arranged at the lower end of the outer side face of the concentration barrel body, the upper surface of the concentration barrel body is connected with a mounting base through bolts, an air guide pipe is arranged at a receding opening formed in the upper surface of the mounting base, and an air suction pipe is arranged at the upper end of the air guide pipe. A fan is arranged on the upper side in the air suction pipe, a heating plate is arranged on the lower side in the air suction pipe, and a heating guide module used for guiding is further arranged in the air guide pipe. According to the heating device for the low-temperature concentrator, the air deflector continuously swings back and forth in the process that the rotating ring drives the air deflector to rotate, and hot air is quickly and uniformly blown into the concentration barrel body, so that the interior of the low-temperature concent
