In general, sintered ore is there is prepared the charged groups sintering the sintered material, sintering starting materials include magnetite (Fe3O4), hematite (Fe2O3) as a main raw material of iron ore, and so on, and this subsidiary materials with other raw materials such as limestone and serpentine, silica sand and calcium oxide which is charged mill scale (mill scale) and the dust (dust), and groups sintering the raw material coke minutes.
[4]
In the process the raw materials for sinter is to be charged into the sintering furnace truck through a charging chute consisting of the deflector plate (deflector plate), or a plurality of rollers, wherein the formulation is relatively large and heavy particles in the material is at the lower end of the sintering balance, fine particles are charged to the upper end It induces mouth piece three pieces so as to improve the permeability in the sintering process.
[5]
The sintering raw material charging chute that is affixed to the surface of the light generated in the process of being charged by generating the mixing of the raw material charge imbalance, and a separate operation for removing the optical these are required. For charging chute composed of a plurality of rollers, is attached to the light are removed by installing a fixed scraper to the lower roller via the scraper when the roller rotates.
[6]
When the material to be dispensed from the drum feeders to immediately fall to the charging chute is the cause of the horizontal charge variations because a drop strength non-uniformity in the horizontal direction. Thus, when installing the swash plate of a predetermined length between the drum feeder and a charging chute, and the raw materials are by a wobble plate friction for moving the swash plate is formed with a certain charge density in the horizontal direction to reduce the horizontal charge variation, the inclined plate the charging chute so as to be installed retracted length, when the anticline narrow space can advantageously secure a fold range of a raw material.
[7]
However, there is a problem that the raw materials are compounded when the horizontal left and right end portions attached to the light generation of the wobble plate while passing through the inclined plate rather increase the horizontal charge variation. Bath agent in order to prevent this, and that but for the optical removed by hand at regular intervals, is accompanied by an increase in work load, and risky business.
[8]
Therefore, the situation than with a simple structure, a new method and apparatus capable of preventing the mechanically attached to the light attachment occurs without the use of a method for inhibiting the flow of the raw material, such as removing the light is required.

Best Mode for Carrying Out the Invention

[47]
Hereinafter, with reference to the accompanying drawings it now is made to the preferred embodiment of the present invention.
[48]
As shown in Figs. 1 and 2, the raw material feeding device according to the invention, comprises a hopper (3000), a drum feeder (2000), charging chute (6000), the swash plate 600 and the cooling unit 620 .
[49]
Hopper 3000 is thereby dispensing a predetermined amount by the raw material for sinter by the rotation of a place where the raw materials for sinter is charged, a feeder drum (2000). At this time, to reduce the discharge variation in the raw materials for sinter by a hopper gate (3000a). To charging chute 6000 is charged to the a configuration that classifies the sintering raw material by size and charge to the sinter the balance (1000), of small particle size material more come above the floor surface of the sintered Balance 1000 discharged from the hopper (3000) intended.
[50]
A hopper (3000), a drum feeder (2000), charging chute (6000) is a general configuration used, in which a more detailed description will be omitted.
[51]
Swash plate 600 is configured to deliver the raw materials for sinter to be discharged from the drum feeder (2000) in charging chute (6000). Inclined plate 600 has the structure of the plate, the drum feeder (2000) is installed in the direction in which the sintered material is discharged is provided so that gradually decreases in the direction towards the charging chute (6000).
[52]
The tilt plate 600 is able to impair than the separation between a configuration for reducing the width direction of the deviation of the raw materials for sinter was kept constant the supply density of the sintered material, a drum feeder (2000) and a charging chute (6000) and it performs a variety of roles, such as.
[53]
Although not shown, both ends of the width direction of the swash plate 600 is installed it blocks blanking plates to the raw material is falling to the left and right sides of the tilt plate 600. The However, the shielding material to the influence of the plate being stacked on each side end portion of the swash plate 600, to the problem that they are grown to an optical generation.
[54]
To address this, a cooling unit 620. A cooling unit 620 as a configuration for cooling the swash plate 600, thereby condensing the water in the cooling surface 620 to form a water film. There is the raw material for sinter composed of iron ore, coke, etc. of the differential as a pseudo-particle assembly using the water, it is to condense the moisture contained in these raw materials for sinter to the surface of the inclined plate 600. The
[55]
When the surface of the swash plate 600 is the water to condense water film is formed, due to the frictional force of the swash plate 600 is decreased to fall becomes the raw material is slipped more easily it is possible to prevent accumulation of material. This is primarily to prevent that the attachment of light occurs over.
[56]
Sintering raw material is limestone which are included, are the optical forming the Ca in these limestone causes a reaction and impurities in raw materials and cement screen. At this time, if there is a water film is formed on the surface of the swash plate (600), calcium carbonate (CaCO caused the cement screen 3 a) calcium bicarbonate (Ca (HCO soluble in water 3 ) 2 can be converted into a). Accordingly, the attachment can be prevented the light Cement Chemistry, meaning that the optical removed easily due to the weight of the raw material. This is capable of preventing the attachment of light generated secondarily.
[57]
As described above, the optical formed in the inclined plate 600 is mostly formed in the both side ends of the inclined plate 600. The This means that means that, in order to prevent adhesion of light occurs must form a water film on both side ends of the inclined plate 600. The
[58]
Therefore, the cooling unit 620, it is preferable to locally cool the end portions of both side surfaces of the swash plate 600. The
[59]
The cooling unit 620, the heat exchanger 621, a tilt plate (600) provided inside, so is provided on the outside of the inner pipe 624, a tilt plate (600) arranged in a staggered pattern inside the pipe (624) end and with heat exchanger 621, the supply pipe 622 which connects between the conveying a refrigerant, the refrigerant is provided on the outside of the inclined plate 600 connecting the other end of the heat exchanger 621 of the inner pipe 624, It is configured to include a return line 623 for transferring. Here a pump (not shown) and a control unit (not shown) for controlling the refrigerant circulation rate of the pump for circulating the refrigerant in may further include.
[60]
The inner pipe 624 to cool the both side ends of the inclined plate 600, is inserted into the installation of the inclined plate 600. The The inner pipe 624 may both ends are protruded to the side of the inclined plate 600, are arranged in a zigzag form in the interior of the swash plate 600 more effectively absorbed the heat of the swash plate 600. The
[61]
The center portion of the swash plate 600, does not have good attachment light generation, there is no need to unnecessarily cool the entire swash plate 600. The Thus, the wobble plate 600 will be effective in mounting if the inner pipe 624 is inserted into the area of ​​a quarter each of the sides in the entire area to prevent the light generated.
[62]
If over the entire area of ​​the tilt plate 600, inner pipe 624 is inserted, increasing the amount of refrigerant that needs and, since the rotation speed of the refrigerant also ppalrajyeoya, will be able to call up the resource and energy waste.
[63]
As Figure 4 and shown in Figure 5, it increases the amount of theoretical condensate coefficient of heat transfer with the water as the flow rate of the refrigerant increases.
[64]
The control unit to control the operating speed of the pump to control the flow rate of the refrigerant, heat transfer rate is 635W / m 2 or more, theory 92.5g / hr.m amount of condensed 2 is preferred to control the pumps so that they are at.
[65]
For the condensation and, this raw material coating weight according to by cooling was tested as follows.
[66]
After inserting the round bar within the block of iron material such as a wobble plate, and passed through the refrigerant to the inside of the round bar. Round bar is a pipe shape having an outer diameter of 20mm, was passed through the coolant 5 to the interior to 7L / min was confirmed whether or not the optical generation of the metal block surface.
[67]
Iron block planar area of 0.108m 2 was per unit of heat transfer rate is 635 W / m to 40 based on the outside air 2 was. At this time, a surface temperature of the steel block is 5.8, amount of water condensed is 92.5g / hr.m 2 was. These were in the same conditions did not occur with the optical is, the optical generation cause the calcium oxide particles and fine raw material by the water film on the metal block surfaces Rimed was confirmed washed down by the lubricating action and gravity of the water film.
[68]
Thus, the heat transfer rate per unit area is 635W / m at the surface 2 is above the water film is formed by condensation, it can be expected that there is attached to the light generated by the lubrication can be suppressed.
[69]
[70]
Raw material feeding apparatus according to the present invention comprises charging chute (6000) it comprises at least one roller for guiding the sintering raw material which is supplied from a drum feeder (2000) in the sintered balance; is the surface comprising, at least one or more of the plurality of rollers to a cooling roller to inhibit the optical caused by a water film caused by cooling.
[71]
At least one of the drum feeder (2000) the plurality of rollers constituting the charging chute (6000) for guiding the side of the sintered balance the sintering raw material is supplied from this that fine material and calcium oxide according to comprised of a cooling roller which is itself a water film formed on the surface without being attached to the roller will fall between the rollers by the water film. By minimizing the time for which the fine-grained material such as calcium oxide, and stay on the surface of the roller in this way it is to prevent the phenomenon that the optical adhere to the surface of the roller.
[72]
Preferably a plurality of rollers of the cooling roller can be prevented from charging chute (6000) so as to implement a more uniform raw material for sinter layer surface at the bottom side by the problem of strength of sintered ore upper weakening.
[73]
[74]
Cooling roller outer shape portion 100 of the hollow cylindrical shape; And protruding at both ends of the outer part 100 in the longitudinal direction, a cylindrical shape the diameter of the cross-sectional outer contour unit 100, the pair of the rotary shaft portion is smaller than the diameter of the cross section; And is disposed in the interior of the outer part 100, a cylindrical outer diameter is smaller than the inner diameter of the outer member (100), had a length less than the length of the outer portion 100, a surface associated with the inner contour part 100 part (300) within which the fixing protrusion is formed by outer portion 100 and a predetermined distance apart that is; a, the flow which the cooling fluid flow through the gap spacing between the outer portion 100 and the inside part (300) comprising: ( 1) to ensure that the water film formed on the surface of the outer part 100 by the cooling fluid moving along the (1) to flow to the said formed.
[75]
[76]
The cooling roller, the cylindrical shape of the hollow outer section 100 as a constituent of the charging chute (6000) for guiding the raw material for sinter in sintering the balance as shown in Figure 6 in accordance with the present invention; And protruding at both ends of the outer part 100 in the longitudinal direction, the diameter of the cross-sectional outer contour portion 100 is smaller than the diameter of the cross section one pairs of the rotary shaft portion 200 as a cylindrical shape; And the outer shape is disposed in the interior of the part 100, had the outer diameter is smaller than the inner diameter of the outer portion 100 as a cylindrical shape and a length smaller than the length of the outer portion 100, a surface associated with the inner contour part 100 part (300) within which the fixing protrusion is formed by outer portion 100 and a predetermined distance apart that is; a, the flow which the cooling fluid flow through the gap spacing between the outer portion 100 and the inside part (300) comprising: ( 1) is formed.
[77]
External unit 100 should perform the function of the roller constituting the charging chute 6000. Since appearance is preferably formed in a cylindrical shape.
[78]
At least one side of the rotary shaft portion 200 extending in a longitudinal direction at both ends of the cylindrical shape, the drive unit (M) is connected to and rotates the outer member (100).
[79]
Inside and within the depth of the hollow type outer part internal space within the mandrel 300 is disposed within core 300 of the 100 is formed to a smaller size than the inner space of the outer portion 100 outer portion 100 ( 300) there is no gap between the outer side can be provided for.
[80]
However, the outer part within the mandrel (300) and simultaneously provide a gap of a predetermined distance away from the inner space (100) is fixed to a projection on the surface of the inside part (300) so as to rotate integrally with the outer member (100) provided by connects outer and inner member (100). The projections are preferably able to guarantee a stable position inside the outer part space (100) is formed as two or more than two.
[81]
Also the spaced through openings in the outer portion 100 and within the core 300 as shown in Figure 7 may be a cooled fluid flow. If the cooling fluid is lower than the room temperature by condensing maethige the outside air to the surface of the water vapor in the air to outer portion 100. The thus condensed water vapor is formed on the surface by being a water film will be formed on the surface of the outer member (100).
[82]
If a water film formed on the surface of the roller 21 constituting the charging chute (6000) the same principle as the raw material is fine and the calcium oxide does not adhere to the roller 21 is dropping between the rollers by the water film. By minimizing the surface time at which the raw material such as fine granules and calcium oxide stay on the roller 21 in this manner is to prevent the phenomenon that the adhesion to the surface of the roller 21, the light fastness.
[83]
When the light is attached to one end fixed to the surface of the roller 21 is growing rapidly as a result of the charge imbalance caused by sintering a raw material and causing disruption to the operation bar is a separate operation for removing the optical requirements accordingly.
[84]
By artificially forming a water film on the surface of the roller 21 to prevent the occurrence of problems as described above inhibits the attachment of light occurs.
[85]
Preferably, if the cooling fluid uses a mixed solution of water and antifreeze. For the winter because it is not possible to move the water freezing to lower the freezing point of water by mixing the anti-freeze to prevent this phenomenon.
[86]
