In one aspect of the invention, the invention proposes a kind of industrial furnace feed systems, according to an embodiment of the invention,
With reference to Fig. 1-2, which includes: industrial furnace 100, charging chamber 200, feed bin 300, scarfing cinder channel 400 and belt porch 500.
According to an embodiment of the invention, industrial furnace 100 is equipped with feed inlet 101.According to one embodiment of present invention, work
The concrete type of industry furnace 100 is not particularly restricted, and those skilled in the art can select according to actual needs, such as can
Think a variety of stoves of the existing industrial application such as bottom convertor or side-blown converter.It should be noted that the position of feed inlet is not by spy
It does not limit, those skilled in the art can select according to actual needs, it is preferred that feed inlet 101 can be located at industrial furnace
100 top.It is more advantageous to the arrangement of industrial furnace feed system, as a result, so as to which the scarfing cinder of feed inlet is better achieved.
According to an embodiment of the invention, charging chamber 200 is connected to and is located at the surface of feed inlet 101 with feed inlet 101.Hair
On the one hand bright people discovery is conducive to material from feed inlet vertically into work by being arranged charging chamber right above feed inlet
In industry furnace, it on the one hand can prevent the high-temperature fusant that splash goes out in industrial furnace from splashing to outside furnace.
According to an embodiment of the invention, feed bin 300 is connected to by scarfing cinder channel 400 with charging chamber 200, and scarfing cinder channel
Dross extractor 41 is equipped in 400, dross extractor 41 moves between scarfing cinder channel 400 and feed inlet 101.When dross extractor moves down
When to feed inlet, scarfing cinder is realized, when dross extractor is moved upward to scarfing cinder upper part of channel, stop scarfing cinder.Inventors have found that passing through
The dross extractor that can move between scarfing cinder channel and feed inlet is being set in scarfing cinder channel, can by slag that feed inlet inner wall bonds and
When remove, avoid the occurrence of the situation that feed inlet is blocked and can not be fed, while eliminating special messenger's scarfing cinder, saved labour at
This, also avoids the case where high-temperature material goes out's to burn operative employee from feed inlet splash generation.It should be noted that feed bin and scarfing cinder
The connection relationship in channel is not particularly restricted, and those skilled in the art can select according to actual needs, such as feed bin
300 can be connected with the middle section in scarfing cinder channel 400.

This, can be directly to when the dross extractor in scarfing cinder channel is moved along scarfing cinder channel up to feed inlet, to realize that feed inlet removes the gred.
The angle of a specific embodiment according to the present invention, scarfing cinder channel 400 and charging chamber 200 can be 30-40 degree.Invention human hair
It is existing, it can further improve scarfing cinder efficiency and scarfing cinder effect in the angular range.If the angle of scarfing cinder channel and charging chamber is excessive,
It easily causes charging to have some setbacks, leads to the reduction of scarfing cinder efficiency.Still another embodiment in accordance with the present invention, the downstream in scarfing cinder channel 400
101 top of feed inlet can be located at.Dross extractor can be mentioned significantly once going out the reachable feed inlet realization slagging-off in scarfing cinder channel as a result,
Height slagging-off efficiency, and then improve production efficiency.
According to still another embodiment of the invention, sharp portion 411 can be formed on the bottom of dross extractor 41.Inventors have found that
When dross extractor is moved to feed inlet from scarfing cinder channel, the sharp portion of dross extractor bottom can quickly be removed slag on feed inlet, be mentioned
High scarfing cinder efficiency and scarfing cinder effect.The size of dross extractor is not particularly restricted, and those skilled in the art can be according to practical need
It is selected, a specific embodiment according to the present invention, the outer diameter of dross extractor can account for the 80- of scarfing cinder channel internal diameter
90%.When moving up and down progress scarfing cinder in scarfing cinder channel when dross extractor as a result, material also can still be entered by scarfing cinder channel
Into industrial furnace, it is not necessary to which the blowing out for scarfing cinder is conducive to raise labour productivity, and reduces production cost.Dross extractor it is specific
Type is also not particularly limited, and those skilled in the art can select according to actual needs, such as dross extractor can be column
Plug dross extractor.It should be noted that scarfing cinder frequency is not particularly restricted, those skilled in the art can be according to actual production
Situation flexible setting, and artificial field control can be used to the control of scarfing cinder frequency, it is also remote controlled.
According to still another embodiment of the invention, belt porch 500 is connected with feed bin 300.It as a result, can be by belt porch by object
Material is sent to feed bin.
Industrial furnace feed system according to an embodiment of the present invention, by being arranged charging chamber right above feed inlet, a side
Face is conducive to material from feed inlet vertically into in industrial furnace, on the one hand can preventing the high-temperature fusant that splash goes out in industrial furnace from splashing
To outside furnace；It, can will be in feed inlet by the way that the dross extractor that can move between scarfing cinder channel and feed inlet is being arranged in scarfing cinder channel
The slag of wall bonding is removed in time, avoids the occurrence of the situation that feed inlet is blocked and can not be fed, while eliminating special messenger's scarfing cinder, is saved
Labor cost also avoids the case where high-temperature material goes out's to burn operative employee from feed inlet splash generation.The system can as a result,
Facilitate the bond amount for removing charging discharge surface splashings, mitigates worker and clear up the labor intensity of feed inlet, while blowing out can be reduced
The problem of special cleaning feed inlet causes, raises labour productivity, reduces production cost.
