The the first control valve 41 entered in industrial furnace 3 with the material in control pretreating containers 1.
Feed arrangement provided in an embodiment of the present invention, material is introduced into pretreating containers 1, by adding for heating arrangements 2
Heat so that the combination oxygen in material becomes free oxygen, or the combination oxygen in the impurity in material is become into free oxygen, Ran Houtong
Cross the carrier gas that carrier gas inlet 13 entered to take free oxygen out of from carrier gas outlet 14, realize to oxygen in material in pretreating containers 1
Separation, so as to reduce the content of oxygen in material, when material is controlled by after deoxidation treatment, opening first in pretreating containers 1
Valve 41, the material after deoxidation in pretreating containers 1 enters in industrial furnace 3；It is complete after material completes sintering in industrial furnace 3
The discharge in the industrial furnace 3 into the material after sintering, then by the first control valve 41 directly to being fed in industrial furnace 3, after
Continuous sintering, compared with prior art, during industrial furnace 3 feeds, it is not necessary to wait industrial furnace to cool down, directly feeds,
So that the sintering of industrial furnace 3 can be carried out persistently, the efficiency that industrial furnace life 3 is produced is improve, and saved the energy, improve the energy
Utilization rate.
Wherein, pretreating containers 1 are closed vessel, and predominantly material deoxidation treatment provides place.
Heating arrangements 2 are preferably induction coil heating, naturally it is also possible to be other heating arrangements.
Carrier gas source can be storage container for storing carrier gas, or is provided with 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.
Feed arrangement 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 with pretreating containers 1, and magazine 5 is connected with industrial furnace 3, is connected with magazine 5 in pretreating containers 1
Place is provided with the second control valve 42 for controlling the material in pretreating containers 1 to enter in magazine 5, the first control valve 41
It is arranged on magazine 5 and the connectivity part of industrial furnace 3.
The regular hour is needed because material carries out deoxidation treatment in pretreating containers 1, if however, carried out in material
In this time of deoxidation treatment, it is necessary to wait the material deoxidation process in pretreating containers 1 when needing to feed in industrial furnace 3
Complete, thus, industrial furnace 3 can be caused to feed and stopped within a period of time, the efficiency of production is influenceed to a certain extent.
Therefore, the embodiment of the present invention is provided with magazine 5.The closed setting of magazine 5 first, it is to avoid after deoxidation treatment
Material contacted with the oxygen in air again；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 the second control valve 42 causes deoxidation
Stored in into magazine 5, in this way, the deoxidation process of pretreating containers 1 can be carried out persistently；When industrial furnace 3 needs
During charging, valve 41 is controlled by opening first, 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 in the absence of mutually restriction and influence situation so that the high efficiency of the production of industrial furnace 3.
Feed arrangement provided in an embodiment of the present invention, can also include being provided with displacement in displacement apparatus 6, displacement apparatus 6
Chamber, and with the displacement gas feed 61 that connect of chamber and gas vent 62, for being connected with carrier gas source, gas goes out for gas feed 61
Mouth 62 is provided with for preventing from replacing the screen pack that material flows out with carrier gas from gas vent 62 in chamber, replaces chamber and magazine
5 connections, and connected with industrial furnace 3.
Firstly the need of explanation, the setting of displacement apparatus 6 can in the material exported in magazine 5 for replacing
The oxygen that can exist.At the beginning of magazine 5 is connected installation with industrial furnace 3, can there is sky in magazine 5 with the junction of industrial furnace 3
Gas, when the material after deoxidation enters the region, the oxygen in air can enter in industrial furnace 3 together with material, so as to industry
The quality of the product of the sintering of stove 3 is impacted.In order to exempt the occurrence of this, displacement apparatus are provided with the embodiment of the present invention
6.Its detailed process is that the carrier gas that carrier gas source is provided 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 be carried out during the blowing of magazine 5,
Can also be carried out during magazine 5 stops blowing.
When feed arrangement only includes pretreating containers 1 with industrial furnace 3, displacement apparatus 6 can be arranged on pre- place and enter container 1
Between industrial furnace 3.
Certainly, displacement apparatus 6 can also include being arranged on the extraction sector of gas vent 62, and extraction sector is in displacement chamber
It is evacuated, because the carrier gas that carrier gas source is provided enters displacement chamber by gas feed, is then flowed out by gas vent 62 and put
The process in chamber is changed, the power for mainly being provided in itself by carrier gas source, after extraction sector is provided with, the carrier gas of carrier gas source can be faster
The oxygen replaced in chamber is taken out of by gas vent 62 by gas feed 61 in ground, or by the material in displacement chamber
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
Gas in displacement chamber is taken 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 property of connection, in the embodiment of the present invention, bellows 7, ripple is arranged with displacement apparatus 6 away from one end of industrial furnace 3
Pipe 7 is connected away from one end of displacement apparatus 6 with magazine 5.
In the embodiment of the present invention, the 3rd control valve 43 is additionally provided with 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 by after deoxidation treatment, and due to magazine
5 is closed container, extremely low without oxygen or oxygen content in the material in magazine 5, when displacement apparatus 6 are installed,
Magazine 5 is enabled to stop blowing by the 3rd control valve 43 so that oxygen of the magazine 5 in displacement apparatus is replaced
Blowing is carried out again after complete, is prevented effectively from oxygen and is contacted with the material after deoxidation.
The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or uses the present invention.
Various modifications to these embodiments will be apparent for 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, the present invention
The embodiments shown herein is not intended to be limited to, and is to fit to and principles disclosed herein and features of novelty phase one
The scope most wide for causing.
