The utility model ensures fast heating and the high efficiency of electric furnace by the way that air inlet-outlet pipe and heat preserving and insulating material is arranged.But
Be in practical applications, due to exhaust pipe be it is inside direct connection burner hearth and extraneous, will certainly band when exhaust pipe is vented outward
The amount of heat in burner hearth is walked, the heating efficiency of burner hearth is influenced, causes a large amount of meaningless losses of electric energy, and aggregate is in electric furnace
In baking process, some toxic gases and micronic dust certainly will be will produce, if these are expelled directly out, the environment of surrounding can also be caused
Pollution.
Invention content
The purpose of the present invention is overcoming the defect of existing technology and deficiency, provide it is a kind of it is simple in structure, heat insulation effect is good, energy consumption
The high temperature electric elevator furnace low, environmental pollution is small.
In order to achieve the above object, technical solution of the invention is：A kind of high temperature electric elevator furnace, including furnace shell, setting
Burner hearth inside furnace shell and furnace bottom hoistable platform, the furnace shell include furnace body and furnace roof, and the bottom of the furnace body is provided with stove
Bottom hoistable platform is connected with the fire door for closed furnace inner cavity above the furnace bottom hoistable platform, is arranged on the furnace roof
There is heating element and exhaust pipe, the heating element to stretch into inside burner hearth, be provided with below the burner hearth inside connection burner hearth with
Extraneous air inlet pipe, it is characterised in that：The periphery of the furnace shell is provided with interlayer, the side of the interlayer and the top phase of burner hearth
Connection, the other side of interlayer is connected with exhaust pipe.
Water or other are provided in the interlayer can play the role of the material of adsorption cleaning.
The connectivity part of the interlayer and exhaust pipe is both provided with filter screen.
The air inlet pipe passes through inside interlayer.
The temperature control element stretched into inside burner hearth is installed on the furnace roof.
The bottom of the interlayer is provided with discharge valve.
Compared with prior art, the present invention haing the following advantages：
1, the interlayer that the present invention is communicated in the periphery setting of furnace shell with inside it carries great quantities of spare in this way when electric furnace works
The flue gas of heat can first pass through interlayer, then be discharged into air through exhaust pipe, and the interlayer heated by high-temperature flue gas can play burner hearth
Insulation effect avoids being largely lost for heat, and the sorbing material for reducing the loss of electric energy, and being arranged in interlayer can also adsorb cigarette
Pernicious gas in gas and micronic dust reduce pollution of the gas being discharged in exhaust pipe to ambient enviroment.
2, the present invention is respectively provided with filter screen in the connectivity part of interlayer and exhaust pipe, can further decrease the micronic dust in flue gas
Content so that the flue gas of discharge reaches the target of " zero-emission ".
3, the present invention in air inlet pipe pass through inside interlayer, the air in such air inlet pipe can by interlayer to its into
Row preheating, due to having simplified preheater, also just reduces the cost and Energy in use of equipment.
4, the present invention can adjust the output of electric energy in real time by the way that temperature control element is arranged by the temperature change in stove, reach
Utilization of power maximizes.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
