It is respectively equipped with thermocouple jack and steam vent.
The compound burner hearth of described Muffle furnace, the heater is resistance-type heating furnace silk or spiral heating resistance wire.
The compound burner hearth of described Muffle furnace, the burner hearth is square or circular configuration.
The compound burner hearth of described Muffle furnace, the shell is hollow shell, and shape and the burner hearth of shell match, shell
It is above uncovered structure, the back side is enclosed construction, and at the back side of shell the thermocouple of setting corresponding with the burner hearth back side is provided with
Jack and steam vent.
The compound burner hearth of described Muffle furnace, the burner hearth and shell are refractory material, and for the fire proofed wood of phase same material
Material, the refractory material includes refractory fibre, high alumina refractories, mullite, cordierite, corundum, quartz.
The compound burner hearth of described Muffle furnace, is provided with metal furnace shell outside burner hearth, in metal furnace shell and the outside of burner hearth
Between be provided with insulation material, being provided with before burner hearth carries out the fire door frame of closed protective to calandria, before fire door frame
Be provided with fire door carries out closing insulation to burner hearth.
As a result of above-mentioned technical proposal, this utility model has the advantages that：
Burner hearth and shell that this utility model passes through setting drawing and pulling type, to change and keeping in repair burner hearth and heating furnace silk；
Calandria is set in heater perforation, makes heater completely isolated with burner hearth, volatilized corrosive gas is touched
Heater, it is thus possible to effectively extend the service life of heater；Steam vent is left at the back side of burner hearth, volatilized corruption is made
Corrosion gas can be discharged smoothly, to reduce its impact to surrounding；Muffle furnace described in the utility model is combined burner hearth
There is corrosivity, the material of toxic gas for material of the calcining with a large amount of escaping gases or product, particularly calcining
Or product has very strong practicality.
