Description
Technical field
The present invention relates to industrial furnace, especially a kind of combined type fire door suitable for being used on industrial furnace.
Background technique
Common mechanical factory is heat-treated (annealing, is tempered, quenched quenching) etc. to machine components and resistance furnace is widely used
Heating, electricity consumption is big, and main cause is that temperature is easily run at fire door, and the effect of two fire doors is sealing fire door, and furnace heat is prevented to scatter and disappear
And the sucking of the outer air of furnace, precision have conclusive influence to the efficiency of chamber type electric resistance furnace and energy consumption；How this is solved
The technical issues of one technology disadvantage is current urgent need to resolve.
Summary of the invention
The purpose of the present invention is design a kind of combined type fire door structurally reasonable, heat insulation effect is good.
The technical scheme is that a kind of combined type fire door, it includes outer fire door, it is characterised in that: on the inside of outer fire door
It is fixed with fire door in frame, interior fire door is fixedly connected by bolt with outer fire door.
The part that interior fire door is contacted with furnace body is equipped with heat insulation layer.
It is provided with strip hole on the frame of interior fire door, carries out certain position adjustment on the inside of outer fire door convenient for interior fire door.
The beneficial effects of the present invention are: structure of the invention is reasonable, the heating efficiency of resistance furnace can be effectively improved, reduction disappears
Consumption.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment:
Embodiment is described in detail in conjunction with the figures above,
A kind of sandbox interior locating device of casting, a kind of combined type fire door, it includes furnace body 3, outer fire door 1, outer fire door inside
Fire door 2 in frame are fixed with, interior fire door is fixedly connected by bolt with outer fire door.
The part that interior fire door is contacted with furnace body is equipped with heat insulation layer.
It is provided with strip hole on the frame of interior fire door, carries out certain position adjustment on the inside of outer fire door convenient for interior fire door.
In the use of the present invention, installing the interior fire door an of frame-type additional again in the inside of outer fire door, further ensure in this way
Furnace body is not easy to reveal heat from the hinged place of outer fire door, can effectively promote the processing efficiency of electrothermal furnace.
The above embodiments are merely examples for clarifying the description, and does not limit the embodiments.For institute
For the those of ordinary skill in category field, other various forms of variations or change can also be made on the basis of the above description
It is dynamic.There is no necessity and possibility to exhaust all the enbodiments, and obvious variation extended from this or change
It moves within still in the protection scope of the invention.
