Description of reference numerals:
the electric furnace comprises an electric furnace body 1, a flange structure 2, a circular flange 3, an electric heating element 4, a transportation protective cap 5, a stainless steel plate 6, a bolt 7, a thermocouple 8, an electric furnace connecting pipe 9 and an aluminum silicate heat preservation felt 10.
Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.
Referring to fig. 1 to fig. 3, the following technical solutions are adopted in the present embodiment: the electric furnace comprises an electric furnace body 1, a flange structure 2, a circular flange 3, an electric heating element 4, a transportation protective cap 5, a stainless steel plate 6, a bolt 7, a thermocouple 8, an electric furnace connecting pipe 9 and an aluminum silicate heat preservation felt 10; the inner side wall of the electric furnace body 1 is provided with a stainless steel plate 6, the outer side of the stainless steel plate 6 is provided with an aluminum silicate heat preservation felt 10, two ends of the electric furnace body 1 are provided with electric furnace connecting pipes 9, the electric furnace connecting pipes 9 are provided with thermocouples 8, the upper end of the electric furnace body 1 is connected with a transportation protection cap 5 through bolts 7, a flange structure 2 is arranged in the transportation protection cap 5, and a circular flange 3 of the flange structure 2 is provided with an electric heating element 4; the electric heating element 4 is a heating element assembly made of stainless steel 321.
When the specific embodiment mode is operated, the internal cutoff surface and the heat exchange area of the furnace body of the heating electric furnace are designed according to electric furnaces with different powers, the design is scientific and practical, and the furnace is reasonable in design and is transformed according to the practical experience of production and use on the basis of the original electric furnaces with the top door and the side door. Two heat-insulating and anti-corrosion gas layers are arranged above the inner part of the electric furnace, high-alumina heat-insulating bricks or aluminum silicate heat-insulating felts are adopted on the periphery in the electric furnace, inner heat insulation and anti-corrosion are carried out on the outer lining stainless steel plate, gas leakage prevention treatment is carried out, and gas leakage prevention protective layers are arranged on the relevant parts such as the entrance and exit of the equipment, the wiring part and the like, so that the electric furnace is integrated, and the gas leakage phenomenon of the equipment in the use of the traditional.
