Description
Technical field
The present invention relates to the tempering furnace of a kind of boiler plant, especially vacuum air-quenching.
Technical background
Current vacuum tempering furnace is usually to be heated under vacuum conditions using internal heat type, high during due to heating in vacuum
Voltage can produce electric discharge and beat arcing phenomenon, therefore must reduce voltage using transformer.150KW, 70V or so transformer
Price is expensive at 40,000 yuan or so.And require higher in vacuum state, heating element heater and cooling material, cost is also high,
So current vacuum tempering furnace is expensive.
The content of the invention
For problem above, it is an object of the invention to provide a kind of tempering furnace of vacuum air-quenching, is that workpiece loads in stove
Close fire door afterwards to be vacuumized by vacuum pump set, vacuum, which reaches, to be heated the outer wall of Muffle pot after requirement, by Muffle
The tank skin of tank carries out heat radiation so as to be heated to product.Strong air-cooler is opened when soaking time reaches requirement to carry out quickly
Cool down to reach efficient purpose.
The technical scheme is that be accomplished by the following way：A kind of tempering furnace of vacuum air-quenching, including it is body of heater, interior
Courage and bell, the body of heater include furnace base, furnace shell and furnace lining, and the furnace shell is fixed on furnace base, has stove in the furnace shell
The burner hearth surrounded is served as a contrast, inner bag is located in burner hearth, and described burner hearth surrounding is fixed with support, and electrical heating elements are fixed on support；
Blower fan apparatus, suspension bracket are fixed with the bell, hand-operated valve, fills protective gas pipe, vacuum-pumping tube, it is characterised in that：Described
Vacuum-pumping tube is provided with magnetic valve.
Water conservation system is connected with vacuum-pumping tube on described bell, hand-operated valve is opened and carries out high-temperature vacuum pumping,
The vavuum pump being connected by water conservation system protection with vacuum-pumping tube.
The screw lift structure installed on the body of heater and bell, for opening and closing bell and body of heater, bell with
Sealing ring is provided between inner bag.
The present invention, simple in construction, reasonable in design, whole stove temperature uniformity is good, and annealing workpiece non-scale produces, and has heated
It can quickly be cooled down after, greatly improve production efficiency, service life length.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Known by Fig. 1, a kind of tempering furnace of vacuum air-quenching, be made up of body of heater 1, inner bag 2 and bell 3, the body of heater 1 includes stove
