Part is communicated with an air blast air inlet pipe, for being connected to blast air with aerator.
Further, the inwall of described cylinder is fixed with heat-insulation layer, for preventing heat energy dissipation with the temperature in holding cylinder body
Degree.
Further, described cylinder is positioned at the part below dividing plate and is also communicated with a combustion gas breather, this combustion gas breather
Gas outlet be positioned on the axis of cylinder, its air inlet is positioned at the outside of cylinder, for connecting with combustible gas storage device
To introduce fuel gas.
Further, the inner bottom surface of described cylinder is inverted taper, and the cone top part of this taper separately has a through hole conduct
Ash discharging hole.
Further, at described cylinder inboard wall, the position of described dividing plate is provided with temperature sensor or thermocouple, is used for
The temperature of monitoring inner barrel.
Further, described cylinder is formed by the Plate Welding that thickness is 10mm；Described dividing plate is the steel of thickness 10mm
Plate, a diameter of 10mm of passage thereon；Described breather is the welded still pipe of Φ 48mm.
Further, described heat-insulation layer is made up of asbestos, refractory brick or other refractory materials.
Compared with prior art, this utility model has the advantages that
1, work efficiency is high, heating uniformity is good.This utility model heats in bottom, air blast, is maintained at one in making cylinder
In the range of fixed temperature, workpiece thermally equivalent can be made, it is to avoid showing of inequality that what the hot spot of oxy arc was concentrated and caused be heated
As, meanwhile, this utility model can heat multiple workpiece simultaneously, improves the efficiency of heating surface.
2, energy consumption is less.This utility model can use coal, imflammable gas to combine or separately as fuel, adds cooperation and protects
The setting of temperature layer, can effectively reduce scattering and disappearing of heat, improve the utilization rate of heat energy, thus reduce energy resource consumption.
3, easy to use.This utility model small volume, conveniently moving, it is applicable to different work condition environments.
4, temperature is easily controllable.This utility model can control burning by the intake of regulation air, thus reaches
The effect of regulating and controlling temperature.After adding device for monitoring temperature, temperature controlled precision can be improved.
5, safety is high.Owing to heating part of the present utility model is in inner barrel, cylinder inboard wall arranges heat-insulation layer,
So can make major part heat accumulation in cylinder, thus decrease the probability of the burn to crowd movable around.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is A-A face of the present utility model generalized section；
Fig. 3 is diaphragm structure schematic diagram of the present utility model；
In accompanying drawing: 1 cylinder；2 dividing plates；21 passages；3 air blast air inlet pipe；4 heat-insulation layers.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is described in further detail.
One, a kind of miniature workpiece heating furnace, as Figure 1-3, including the cylinder 1 that the upper end as shaft is uncovered, also wraps
Include the dividing plate 2 being horizontally set on described cylinder 1 bottom, described dividing plate 2 uniformly offers passage 21；Described cylinder 1
Part below dividing plate 2 is communicated with an air blast air inlet pipe 3, for being connected to blast air with aerator.
This utility model heats in bottom, air blast, is maintained in certain temperature range, workpiece can be made equal in making cylinder 1
Even it is heated, it is to avoid the phenomenon of the inequality of being heated that the hot spot of oxy arc is concentrated and caused, meanwhile, this utility model can add simultaneously
Overabundant heat workpiece, improves the efficiency of heating surface.During use, a certain amount of coal is placed in net-like spacer 2 up-igniting, and uses aerator
Blow.Then workpiece position to be heated is inserted in coal.Range estimation to element heats to can processing temperature, control aerator
Air quantity is incubated.Finally take out part workpiece to be processed.Use complete, close aerator, take out uncombusted coal,
And put out by water with water.
As optimization, the inwall of described cylinder 1 being fixed with heat-insulation layer 4, this is possible to prevent heat energy dissipation to keep cylinder 1
