Carrier gas source connection, discharge port 12 are additionally provided with 3 junction of industrial furnace in discharge port 12 and are used for for being connected to industrial furnace 3
Enter the first control valve 41 in industrial furnace 3 with the material in control pretreating containers 1.
Feeding device provided in an embodiment of the present invention, material are introduced into pretreating containers 1, pass through adding for heating mechanism 2
Combination oxygen in impurity in material so that the combination oxygen in material becomes free oxygen, or is become free oxygen, then led to by heat
It crosses the carrier gas that carrier gas inlet 13 is entered to take free oxygen from carrier gas outlet 14 out of, realize to oxygen in material in pretreating containers 1
Separation, to reduce the content of oxygen in material, when material opens the first control after deoxidation treatment in pretreating containers 1
Valve 41, the material after deoxidation in pretreating containers 1 enter in industrial furnace 3；It is complete after material completes sintering in industrial furnace 3
It is discharged out of industrial furnace 3 at sintered material, is then directly fed into industrial furnace 3 by the first control valve 41, after
Continuous sintering during industrial furnace 3 is fed, withouts waiting for industrial furnace cooling, directly feeds compared with prior art,
So that the sintering of industrial furnace 3 can continue to carry out, the efficiency that industrial furnace raw 3 produces is improved, and saved the energy, improve the energy
Utilization rate.
Wherein, pretreating containers 1 are closed container, and predominantly material deoxidation treatment provides place.
Heating mechanism 2 is preferably induction coil heating, naturally it is also possible to be other heating mechanisms.
Carrier gas source can be the storage container for storing carrier gas, be also possible to be provided on storage container for that will deposit
Carrier gas in storage container is delivered to the pump in pretreating containers 1.Wherein, carrier gas is inert gas.
Feeding device provided in an embodiment of the present invention can also include magazine 5, the closed setting of magazine 5, and storage
Material container 5 is connected to pretreating containers 1, and magazine 5 is connect with industrial furnace 3, is connected in pretreating containers 1 with magazine 5
Place is provided with the second control valve 42 entered in magazine 5 for controlling the material in pretreating containers 1, the first control valve 41
It is arranged in magazine 5 and 3 connectivity part of industrial furnace.
The regular hour is needed since material carries out deoxidation treatment in pretreating containers 1, however, if carrying out in material
In this time of deoxidation treatment, when needing to feed in industrial furnace 3, need to wait the material deoxidation process in pretreating containers 1
It completes, will cause the charging of industrial furnace 3 as a result, and stop whithin a period of time, influence the efficiency of production to a certain extent.
For this purpose, the embodiment of the present invention is provided with magazine 5.The closed setting of magazine 5 first, after avoiding deoxidation treatment
Material contacted again with the oxygen in air；Secondly, magazine 5 plays transfer, in pretreating containers 1 and magazine 5
Connectivity part is provided with the second control valve 42.
After material carries out deoxidation treatment in pretreating containers 1, the material after deoxidation is made by the second control valve 42
It is stored in into magazine 5, in this way, the deoxidation process of pretreating containers 1 can continue to carry out；When industrial furnace 3 needs
When charging, by opening the first control valve 41, the material after the deoxidation in magazine 5 is fed in industrial furnace 3, in this way, de-
The charging of oxygen process and industrial furnace is there is no mutually restricting and influence, thus the efficiency for the production that made high industrial furnace 3.
Feeding device provided in an embodiment of the present invention can also include displacement apparatus 6, be provided with displacement in displacement apparatus 6
Chamber, and the gas feed 61 being connected to displacement chamber and gas vent 62, for being connected to carrier gas source, gas goes out for gas feed 61
Mouthfuls 62 are provided with filter screen flow out with carrier gas from gas vent 62 for preventing from replacing intracavitary material, displacement chamber and magazine
5 connections, and be connected to industrial furnace 3.
Firstly the need of explanation, the setting of displacement apparatus 6 can in the material exported in magazine 5 for replacing
Oxygen existing for energy.At the beginning of magazine 5 connect installation with industrial furnace 3, magazine 5 and 3 junction of industrial furnace can have sky
Gas, when the material after deoxidation enters the region, the oxygen in air can enter in industrial furnace 3 together with material, thus to industry
The quality for the product that furnace 3 is sintered impacts.The occurrence of in order to exempt this, is provided with displacement apparatus in embodiment of the present invention
6.Its detailed process is that carrier gas provided by carrier gas source is entered in displacement apparatus 6 by gas feed 61, in the effect of carrier gas
Under, the air in displacement apparatus 6 is taken out of from gas vent 62.This process can carry out during 5 blowing of magazine,
It can also be carried out during magazine 5 stops blowing.
When feeding device only includes pretreating containers 1 and when industrial furnace 3, displacement apparatus 6 be can be set at pre- place into container 1
Between industrial furnace 3.
Certainly, displacement apparatus 6 can also include the extraction sector that gas vent 62 is arranged in, and extraction sector is intracavitary to replacing
It is evacuated, since the carrier gas that carrier gas source provides enters displacement chamber by gas feed, is then set by the outflow of gas vent 62
The process of chamber is changed, the power mainly provided by carrier gas source itself, after being provided with extraction sector, the carrier gas of carrier gas source can be faster
Ground is taken out of by gas vent 62 by intracavitary oxygen is replaced by gas feed 61, or will be in the intracavitary material of displacement
Oxygen take out of.
It is, of course, also possible to be to close gas feed 61, displacement chamber is vacuumized by extraction sector come realize by
Intracavitary gas is replaced to take out of.
Due to being rigidly connected between displacement apparatus 6 and magazine 5, in order to improve between displacement apparatus 6 and magazine 5
The sealing performance of connection in the embodiment of the present invention, is arranged with bellows 7, ripple far from one end of industrial furnace 3 in displacement apparatus 6
The one end of pipe 7 far from displacement apparatus 6 is connected to magazine 5.
In the embodiment of the present invention, third control valve 43 is additionally provided in the junction of magazine 3 and bellows 7.Due to
Material in pretreating containers 1 is extremely low without oxygen or oxygen content in material after deoxidation treatment, and due to magazine
5 be closed container, extremely low without oxygen or oxygen content in the material in magazine 5, when displacement apparatus 6 is installed,
Magazine 5 is enabled to stop blowing by third control valve 43, so that oxygen of the magazine 5 in displacement apparatus replaces
Blowing is carried out again after complete, and oxygen is effectively avoided to contact with the material after deoxidation.
The foregoing description of the disclosed embodiments enables those skilled in the art to implement or use the present invention.
Various modifications to these embodiments will be readily apparent to those skilled in the art, as defined herein
General Principle can be realized in other embodiments without departing from the spirit or scope of the present invention.Therefore, of the invention
