Detailed Description
The utility model is further illustrated in the following drawings and detailed description, which are not intended to limit the scope of the utility model.
As shown in fig. 1 to 4, the movable split type electric heating device provided in this embodiment includes split electric heaters symmetrically installed at two sides of a heating station of a rotary kiln 10, a moving mechanism installed on each split electric heater, and a slide rail 4 installed below the heating station of the kiln body, the moving mechanism is slidably connected to the slide rail 4, the two split electric heaters are surrounded and separated on the slide rail 4 through the moving mechanism, a heating chamber suitable for the size of the rotary kiln 10 is formed after the two split electric heaters are surrounded and connected, each split electric heater includes a housing 1 and a heating element 2, the housing 1 is in a semicircle shape, and fixing bolts of insulators of the heating element 2 are welded on the inner wall of the housing 1 according to electrical requirements; fixing the heating element 2 on the insulator; the joint of the heating element 2 is protected by an insulating sleeve and then penetrates out of the shell 1 to be connected with an external power supply.
