Spherical electric heating device
2011
The utility model belongs to an electric heating device and specifically relates to a spherical electric heating device. The spherical electric heating device comprises a hollow spherical shell. A red copper lining is disposed in the spherical shell. A frame is arranged inside the red copper lining. Armored heating wires are wound on the frame. Therefore, a spiral heating ball body is formed. The red copper lining is also provided with a thermocouple. Heat conduction metals are filled between the inside of the red copper lining and the outside of the frame. A lead wire pipe is arranged on one side of the spherical shell. The lead wire pipe is communicated with the red copper lining. The advantages of the utility model are that the armored heating wires are wound on the symmetrical stepped round frame and the heat conduction metals are filled in the red copper lining, thereby realizing separate and uniform heat release of spherical particles; and the thermocouple is fixed on the external surface of the red copper lining, such that the surface temperature of the ball body can be measured and a problem of simulation of the spherical particle heating is solved.
