Drying box for chemical detection

The drying box comprises a box body and an air supply fan, electric push rods are fixedly installed on the left side and the right side of the upper end of the box body, the extending ends of the electric push rods are fixedly connected with limiting baffles, one side of each limiting baffle is fixedly connected with a ventilation plate, an exhaust hole is formed in one side of each ventilation plate, and the air supply fan is fixedly connected with the limiting baffles. And the lower end of the inner cavity of the box body is fixedly connected with a rotating seat. Through the effects of the electric push rod, the limiting baffle, the motor, a rotating rod, a first gear, an electric heating wire, a heating box and a rotating seat, the problems that the space of an internal drying chamber of an existing drying box for chemical detection is fixed, when some small chemical products are dried, the temperature rise speed in the large-space drying chamber is low, and the drying effect is poor are solved.
