Abstract
The utility model provides a long-service-life experimental electric furnace which comprises a metal outer shell, high temperature resistant materials, a high-temperature insulating layer, a ceramic heating body, a base plate, a thermal insulation layer, a thermal insulation column, a rotary knob, base feet and a furnace body. The long-service-life experimental electric furnace is simple in structure, small in size, light in weight and convenient to move, achieves insulating heating for to-be-heated items through electrical heating of the ceramic heating body and heat conduction of the metal outer shell, and is safe to use and long in service life.
Description
Technical field
The utility model relates to electric heating equipment field, laboratory, espespecially a kind of long-life experimental electric furnace.
Background technology
In the daily chemical experiment and chemical analysis process in laboratory; usually need some raw materials are heated; perhaps the chemical reaction of some experiments heated; experimental electric furnace is the electric heating equipment of commonly using; traditional experimental electric furnace is because electrical heating wire is exposed outside; directly contact with air; corroded by high-temperature oxydation and chemical reagent; cause often aging fracture of electrical heating wire; so experimental electric furnace is the laboratory equipment that the most easily breaks down, in addition; traditional experimental electric furnace safety in utilization is poor, has certain potential safety hazard.
Summary of the invention
A kind of long-life experimental electric furnace of the utility model is characterized in that overcoming the deficiency of above-mentioned technology, provides a kind of the safe of chemical experiment that be applicable to, the experimental electric furnace of long service life.
To achieve these goals, technical solution of the present utility model is: a kind of long-life experimental electric furnace is by metal shell, exotic material, high-temperature insulating layer, ceramic heating body, base plate, thermal insulation layer, heat insulation post, knob, footing and body of heater form, metal shell, exotic material, high-temperature insulating layer, ceramic heating body and base plate form electric heating body, be installed on the body of heater by heat insulation post, so that electrical heating elements and air insulated, electric device is installed in the body of heater, ceramic heating body is by three ceramic heat monomer compositions, its high temperature resistant wire is connected with electric device in the body of heater respectively, and regulates external power output by the rotation of knob.
The beneficial effects of the utility model are: simple in structure, volume is little lightweight, and conveniently moving by the electrical heating of ceramic heating body and the heat conduction of metal shell, is realized the insulation heating to material to be heated, uses safety, and the life-span is long.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Accompanying drawing 2 is ceramic heating body structural representation of the present utility model.
Among the figure: 1, metal shell, 2, exotic material, 3, high-temperature insulating layer, 4, ceramic heating body, 41,42,43, the ceramic heat monomer, 5, base plate, 6, thermal insulation layer, 7, heat insulation post, 8, knob, 9, footing, 10, body of heater, a, b, c, d, e, f, high temperature resistant wire
The specific embodiment
Shown in accompanying drawing,: a kind of long-life experimental electric furnace is by metal shell 1, exotic material 2, high-temperature insulating layer 3, ceramic heating body 4, base plate 5, thermal insulation layer 6, heat insulation post 7, knob 8, footing 9 and body of heater 10 form, metal shell 1, exotic material 2, high-temperature insulating layer 3, ceramic heating body 4 and base plate 5 form electric heating body, be installed on the body of heater 10 by heat insulation post 7, so that electrical heating elements and air insulated, in the body of heater 10 electric device is installed, ceramic heating body is by three ceramic heat monomers 41,42 and 43 form, its high temperature resistant wire a, b, c, d, e is connected with f with electric device in the body of heater and is connected, and regulates external power output by the rotation of knob 8.
During use, material to be heated is placed on the metal shell 1 of long-life experimental electric furnace, plugged, turn knob 8 is regulated external power output, realizes material to be heated is heated.
The above; embodiment only is that preferred embodiment of the present utility model is described; be not that scope of the present utility model is limited; under the prerequisite of the spirit that does not break away from the utility model technology; various distortion and improvement that this area engineers and technicians make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
