Embodiment Construction

[0014] Further illustrate the present invention below in conjunction with embodiment and accompanying drawing.

[0015] Such as figure 1 , 2 The shown embodiment is an energy-saving experimental electric furnace with electric heating wire as the electric heat source, and the furnace temperature can reach 1000-1200 ° C. It is connected and fixed by the lower temperature box 5 and the upper furnace body to form an integral structure. The frame 1 of the furnace body is composed of special-shaped square tube profiles with symmetrically arranged support edges. The detachable plate 2 is installed on the frame profile support edges by non-falling screws on the top, rear and both sides of the frame, and the front and bottom sides are equipped with Fastened to the fixed gusset 6 on the support edge of the frame profile, wherein the front fixed gusset is provided with an opening corresponding to the furnace mouth. The rail 9 fixed on the lower part of the frame 1 is supported and fixe...

Abstract

The energy saving test electric stove consists of outer casing comprising frame, detachable plate and fixed plates; support tracks fixed on the frame and movable inner casing; hearth of refractory fiber boards and heat insulting layer between the hearth and the inner casing; furnace door and heat energy reflecting boards in the outer casing, heat insulating air layer between the inner casing and the heat energy reflecting boards; and temperature control box with intelligent temperature control instrument in the panel connected to the thermocouple in the hearth and two-way SCR switch. The present invention is energy saving and high in temperature control precision, and has other advantages.

Description

technical field [0001] The invention belongs to an electric heating device, in particular to an energy-saving experimental electric furnace. Background technique [0002] In the known experimental electric furnace in which the furnace body and the temperature control box are combined, the furnace body is composed of an outer shell welded or riveted by guard plates, a furnace structure fixed to the guard plate on the bottom surface of the outer shell, an insulation layer on the surface of the furnace structure, and both sides of the outer shell. The air heat insulation layer between the guard plate and the corresponding insulation layer is formed. The experimental electric furnace using electric heating wire as the electric heat source has a temperature control box consisting of a box body, a panel, a start-stop control switch and corresponding indicator lights, an ammeter, a voltmeter, and a temperature control circuit with silicon controlled rectifiers and thermocouples as ...
