Abstract
The utility model discloses the novel muffle reduction iron production of intermittent type device for a kind of field of metallurgy.Comprise the heating unit at top and the siege of bottom; Wherein, described siege is fixed, and quantity is at two or more, and described heating unit is that integral level is portable, and while moving to each stationary furnace bed position top, integral body covers and seal corresponding siege; Described heating unit comprises burner and flame shield, and flame shield is by burner and siege isolation, and flame shield adopts the refractory materials of accumulation of heat and heat conduction.Combustion zone and reduction zone are separated, and furnace atmosphere is controlled, and reduzate quality is good, can be used for producing granulated iron; Adopt fixed siege, saved the transmission mechanism of most of direct-reduction stove bulky complex, as hearth transmission device of rotary hearth furnace, rotary kiln transmission mechanism, car bottom furnace transmission mechanism etc., energy consumption reduces greatly.
Description
Technical field
The utility model belongs to a kind of non-blast furnace ironmaking device, is specifically related to the novel muffle reduction iron production of intermittent type device for a kind of field of metallurgy.
Background technology
Coal-based direct reduction adopts spacious flame type of heating heating furnace charge conventionally, as rotary hearth furnace, rotary kiln etc., because fuel combustion is oxidizing atmosphere, and the reduction of ferriferous oxide needs reducing atmosphere, therefore spacious flame type of heating exists furnace atmosphere to be difficult to control conventionally, reduzate, easily by the problem of secondary oxidation, affects the final quality of product.
Utility model content
The purpose of this utility model is the deficiency that prior art exists and the novel muffle reduction iron production of a kind of intermittent type device is provided.
For achieving the above object, adopt technical scheme as follows:
An intermittent type muffle reduction iron production device, comprises the heating unit at top and the siege of bottom; Wherein, described siege is fixed, and quantity is at two or more, and described heating unit is that integral level is portable, and while moving to each stationary furnace bed position top, integral body covers and seal corresponding siege;
Described heating unit comprises burner and flame shield, and flame shield is by burner and siege isolation.
Press such scheme, described flame shield adopts the refractory materials of accumulation of heat and heat conduction.
Press such scheme, described heating unit is provided with fume extractor.
Press such scheme, described heating unit and siege are fan-shaped, and heating unit be take the center of circle and covered and seal each siege as fixed point horizontally rotates.
Press such scheme, described heating unit and siege are square or circular, and heating unit moves horizontally and covers and seal each siege.
The utility model beneficial effect is:
Combustion zone and reduction zone are separated, and furnace atmosphere is controlled, and reduzate quality is good, can be used for producing granulated iron;
Adopt fixed siege, saved the transmission mechanism of most of direct-reduction stove bulky complex, as hearth transmission device of rotary hearth furnace, rotary kiln transmission mechanism, car bottom furnace transmission mechanism etc., energy consumption reduces greatly;
In stove, temperature is convenient to control.
Accompanying drawing explanation
1, the utility model vertical view;
2, the utility model sectional view;
1-top firing device, 2-burner, 3-furnace bottom sealing-ring, 4-siege, the 5-bed of material, 6-fume extractor, 7-dividing plate.
Embodiment
Following embodiment is for further understanding the technical solution of the utility model, not as the restriction to protection domain.
Shown in accompanying drawing 1,2, this Novel batch-type muffle reduction iron production device, comprises the heating unit 1 at top and the siege 4 of bottom; Wherein, described siege 4 is fixing, and quantity is at two or more, and described heating unit 1 is that integral level is portable, and while moving to each stationary furnace bed position top, integral body covers and seal corresponding siege 4; Described heating unit comprises burner 2 and flame shield 7, and flame shield 7 is by burner 2 and siege 4 isolation.
Combustion zone and reduction zone are separated, and furnace atmosphere is controlled, and reduzate quality is good, can be used for producing granulated iron.Adopt fixed siege, saved the transmission mechanism of most of direct-reduction stove bulky complex, as hearth transmission device of rotary hearth furnace, rotary kiln transmission mechanism, car bottom furnace transmission mechanism etc., energy consumption reduces greatly.
Optimally, flame shield 4 of the present utility model adopts accumulation of heat and the good refractory materials of thermal conductive property.
There is sealing-ring 3 at the position that heating unit 1 covers siege 4, can adopt water seal.
Heating unit is also provided with fume extractor 6.
During work, when one of them siege is during at cloth, top firing device 1 is positioned at another siege top that is covered with the bed of material 5, wholely covers and seal siege, can adopt water seal by siege air-isolation.Burner 2 burning coal gas, heat is radiated to the bed of material 5 on siege 4 by flame shield 7, furnace charge generation reduction reaction, after having reacted, obtain sponge iron or granulated iron, heater stop burning, move to siege top that another has arranged the bed of material 5, continue heating, the furnace charge having completed on the siege of reduction reaction carries out discharge simultaneously.Go on and so forth.
Heating unit of the present utility model and siege can be designed as fan-shaped, and fan-shaped siege is fixedly installed and forms circularly, and heating unit be take the center of circle and covered and seal each siege as fixed point horizontally rotates.
Heating unit of the present utility model and siege can be designed as square or circular, and heating unit moves horizontally and covers and seal each siege.
