The utility model relates to the technical field of
building material detection equipment, and discloses an electrothermal blowing
drying box which comprises a
drying box body, a
humidity sensor is fixedly installed on the inner wall of the
drying box body, and a partition plate and an inclined plate are fixedly connected to the inner wall of the drying box body. According to the electrothermal blowing drying box, by arranging components such as a
humidity sensor, an inclined plate and a circulating
pipe, external air is sucked in through an air inlet fan and an air inlet
pipe, heating is conducted through a heating wire, hot air rises to dry a
gypsum board, the hot air is guided to the left side of a partition plate through the inclined plate, the hot air can be guided in by the air inlet fan through the circulating
pipe, and circulating drying is achieved; when a
humidity sensor detects that the humidity exceeds a set value, an exhaust fan is started, air with too
high humidity is exhausted through an air outlet pipe through an exhaust head and an
exhaust pipe, efficient drying is achieved, the air with too
high humidity can be prevented from polluting a
gypsum board, a rotating rod is rotated, and through a first
bevel gear, a second
bevel gear, a
threaded rod and a threaded block, the
gypsum board can be conveniently dried. And the object placing plate can be lifted.
