Specifically, notch is opened up on spiral shape feeding-passage c, and when the first feeding cylinder b11 is rotated to notch downward, steel
Ball is dropped down onto automatically in the spiral stream guidance part 3 in roller 2.
First feeding cylinder b11 from 1 inlet end 10 of furnace body to the second feeding cylinder b12 in internal diameter become larger it is pyramidal,
Second feeding cylinder b12 is arranged far from the end horizontal that furnace body 1 is fed to 2 internal stretch of roller from the first feeding cylinder b11, and second
The inside of roller b12 is filled with heat insulation layer b13.
In this example, the centerline collineation of 2 three of the first feeding cylinder b11, the second feeding cylinder b12 and roller is arranged.
Then, in order to prevent in the gas leakage to furnace body 1 of 2 inlet end of roller, in this example, feed device further includes setting
It sets in the first periphery feeding cylinder b11 and by the connector of 2 inlet end of roller sealed connection, wherein connector is rotatably arranged on furnace
The inlet end of body.The setting of the connector, it is mainly that feeding cylinder and helix drum fixation is integral, so, charging
Cylinder and helix drum rotate together, and when the first feeding cylinder is rotated to notch downward, steel ball is dropped down onto helix drum.
Transport mechanism b2 includes the storage bin b20 with first passage door b201, docks with the outlet end of storage bin b20
And the midway storehouse b21 with second channel door b212, the transmission for docking midway storehouse b21 with the inlet end 10 of furnace body 1
Channel b22, wherein storage bin b20 is located above the b21 of midway storehouse, when first passage door b201 is opened, second channel door b212
Closure setting；When second channel door b212 is opened, first passage door b201 closure setting.
Although this feed for carrying out batch steel ball using midway storehouse b21 is the conventional means of this field, in this Shen
Please in, there is a very unexpected technical effect, that is: further combined with spiral shape feeding-passage c, thoroughly shut out
Insulation gas and protective atmosphere leak, energy saving, and then substantially reduce steel ball hot processing cost.Therefore, the technology effect of institute's band
Fruit is very significant.
Specifically, the discharging of midway storehouse b21 is turningly arranged in from a side around horizontal direction by second channel door b212
Mouthful, Transfer pipe b22 outlet end protrudes into the inside of the first feeding cylinder b11.
In this example, heating furnace further includes feeding unit material e of the quantitative offer steel ball to storage bin b20, and feeding unit material e includes

It opens, the steel ball after elevator e5 will be quantified is promoted to storage bin b20.
It is not described in detail herein as elevator e5 for conventional setting.
For this block is counted weight, in conjunction with shown in attached drawing 4, the weight calculation process of steel ball is as follows:
1, steel ball is dropped in steel ball material stock storehouse e1 in the hopper e2 configured with oscillator e3；
2, steel ball is shaken by oscillator e3 in hopper e2 and is delivered in the collecting tank e41 of weight calculation mechanism e4.
3, when steel ball weight reaches setting value, weight calculation mechanism e4 balance is triggered close to switch, balance sensor receives
Balancing information simultaneously signals to PLC controller.
4, PLC controller assigns halt instruction to oscillator e3, then passes through cylinder e6 for the envelope of collecting tank e41 discharge port
Door e7 is opened, and by the rising hopper of Steel ball conveyor to elevator e5, after steel ball collecting tank e41 completion of discharge, cylinder e6 is again
The closure door e7 of collecting tank e41 is closed, and then completes a quantitative feeding of steel ball.
Meanwhile as can be seen from FIG. 4, cylinder e6 and closure door e7 and collecting tank e41 is located at the right side of pivot e40, clump weight e43
Positioned at the left side of pivot e40, and, collecting tank e41 is obliquely installed from top to bottom, the setting that closure door e7 is rotated from the connecting shaft of bottom

Ensure equipment safety.
As for atmosphere protection component 7, the protective atmosphere formed is nitrogen and Deposition During Propane Pyrolysis gas, is made certain in roller 2
Carbon potential, it is ensured that bearing steel ball not decarburization.
As for oily curtain 9, one side is with twice access door and spiral shape feeding-passage, so that steel ball is in input and output material
During will not generate leaking for hot gas and protective gas, reduce heat treatment cost；Production when on the other hand preventing steel ball quenching
Raw oil vapour enters in furnace body, so, can prevent carbon distribution or the corrosion of burner hearth, while also ensuring that the quality of steel ball.
In conclusion the present embodiment has the advantage that
1, the present embodiment can realize that steel ball transmits in heating furnace in steel ball roll procedure, so that steel ball heating is more
Uniformly, to improve the quality of steel ball heat treatment；
2, by the setting of twice access door, spiral shape feeding-passage and oily curtain, so that steel ball is during input and output material
Leaking for hot gas and protective gas will not be generated, heat treatment cost is reduced；
3, under the setting of relief valve assembly, once exploding, the pressure that explosion generates can be leaked rapidly, it is ensured that set
Standby safety；
4, under protective atmosphere protection, make carbon potential certain in roller, it is ensured that bearing steel ball not decarburization；
5, under the premise of quantitative and batch realization steel ball feed, it can be realized steel ball heat treatment process and belong to continuously
Property, and therefore periodicity disclosed in non-existing octagonal rotary drum furnace has the raising of conspicuousness, and quality in terms of production capacity
Also relatively stable.
The utility model is described in detail above, its object is to allow the personage for being familiar with this field technology can be much of that
It solves the content of the utility model and is implemented, do not limit the protection scope of the present invention, it is all practical according to this
Equivalent change or modification made by novel Spirit Essence should all cover within the protection scope of the present utility model.
