The present invention relates to a raw material processing apparatus and a raw material processing method, and more particularly, to a raw material processing apparatus and a raw material processing method capable of suppressing or preventing generation of residues in a luggage without stopping the operation.

In the process of sinter ore production, fine iron ore is sintered and manufactured to a size suitable for use in a furnace. In this sintering process, mixing and humidity (raw material weight ratio of about 7 ~ 8%) is put into a drum mixer, and sintering raw material is pseudo-granulated by adding minute iron ore, subsidiary raw material and fuel (minute coke and anthracite) The surface is ignited by an ignition furnace, and the air is forcedly sucked from below, so that the sintering material is sintered and sintered light is produced. The sintered ores that have been sintered are cooled in a cooler through a crusher of the light pipe and classified to a granular size of 5 to 50 mm which is easy to be charged and reacted in the blast furnace and transferred to the blast furnace.

However, after the sintered light in the sintered bogie is shined in the light-guiding portion, a sintered light (hereinafter referred to as "residual light" The residual light is attached to the sidewall or bottom surface of the sintered bogie, and when the sintered bogie rotates to charge the sintered blend material, the bottom surface of the sintered bogie is directed downward and the residual light in the sintered bogie is separated from the sintered bogie And is loaded into a lower hopper provided at the lower part of the moving path of the sintered bogie. Nevertheless, the sintered bogie still has residual light that is fused to the sintered bogie during sintering, so that the raw material can not be uniformly charged into the sintered bogie when the subsequent sintering blend material is charged.

It will be apparent to those skilled in the art that the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, It is provided to let you know.

The present invention can prevent or prevent foreign matter from remaining in a bogie during the processing of various raw materials by using a movable bogie. At this time, the raw material may be magnetizable magnetic material. Hereinafter, an example will be described in which the generation of the residual light in the sintered bogie during the light distribution can be suppressed by separating the sintered light from the inner wall of the sintered bogie by generating vibration in the sintered bogie before shining the sintered light. Here, the transportable truck can be a sintering truck, and the raw material can be sintered ores.

FIG. 1 is a view showing a raw material processing apparatus according to an embodiment of the present invention, FIG. 2 is a view showing a state where sintered light is shined in a light shading part, and FIGS. 3 and 4 are views showing a raw material processing apparatus according to an embodiment of the present invention. FIG. 5 is a view showing an arrangement of electromagnets installed in a cooling region, and FIG. 6 is a view showing a power application pattern.

Referring to FIG. 1, in the sintering plant, the sintering bogie 40 moves along a path of an endless track shape. The moving path 55 of the sintering bogie 40 includes an upper region where sintered light is produced and a lower region used as a path for distributing the sintered light and returning for a subsequent process.

The production of the sintered ores can be carried out as follows.

First, a large amount of various raw materials stored in a raw material reservoir (not shown) and a coke as a subsidiary raw material are extracted by a weighing belt (not shown) in an appropriate amount, mixed with moisture in a blender (not shown) (Not shown) and temporarily stored in the waste hopper (not shown).

Thereafter, the upper light and the sintering material are charged on the sintering truck 40 in the material supply unit 20 including the surge hopper, the upper light hopper (not shown), the charging chute (not shown), and the like. The sintered bogie 40 containing the sintering compound material is ignited at the upper portion of the sintering blend material due to the coke as a subordinate material while passing through the lower portion of the ignition furnace 30. The sintered bogie 40 having the complex sintered blend material proceeds to the side of the crusher 60, that is, to the side of the light shading portion. At this time, the suction air volume of the main blower (not shown) (10) to suck the complexed sintering compound material on the sintering bogie (40). By the time when the sintering bogie 40 reaches the side of the light-exiting portion where the moving direction is changed owing to the suction air volume of the main blower, the blending raw material on the sintering bogie 40 is sintered to the lower portion to produce the sintered light S. The process up to this point is carried out in the upper region of the movement path 55.

The sintered light S in the sintering bogie 40 is then shined in the light shading portion provided at one side of the upper region and is introduced into the crusher 60. The sintered light S is crushed to a predetermined size or less in the crusher 60, And cooled to a predetermined temperature. Then, the sintering bogie 40 distributes the sintered light S, moves along the lower region of the movement path 55, and returns to the upper region for manufacturing the sintered ores.

However, even if the sintered light S accommodated in the sintering bogie 40 is shined in the light-guiding portion 40, the sintered light that has not been exhausted remains in the sintering bogie 40 as shown in FIG. 2 (hereinafter referred to as "residual light S1" Quot;). When the sintered bogie 40 moves to the lower region and the bottom surface of the sintered bogie 40 faces downward, the residual light S 1 is adhered to the sidewall or bottom surface of the sintered bogie 40, 40 are charged into the lower hopper 80 provided below the lower region. However, when the sintering blend material is fused to the sintering bogie 40 due to excessive heat or the like during sintering, the sintering bogie 40 is not completely removed from the sintering bogie 40 even if the slave bogie 40 moves to the lower region.

In the present invention, in order to suppress the generation of the residual light in the sintering bogie (40) during the light distribution, the sintered bogie (40) Can be separated. Therefore, it is possible to suppress or prevent the generation of the residual light in the sintered bogie 40 after the light distribution of the sintered light is performed. Accordingly, it is possible to suppress or prevent the non-uniform charging of the sintering blend material in the sintering bogie 40 by the residual light S 1 during the charging of the sintering blending raw material for the subsequent process.

The raw material processing apparatus according to the embodiment of the present invention may include the magnetizing apparatus 100 provided in the moving path 55 of the sintering bogie 40. [ The magnetizing apparatus 100 includes an electromagnet 110 provided in at least a part of the moving path 55 of the sintering bogie 40 and a power source unit 120 and a power source unit 120 for applying power to the electromagnet 110 And a control unit 130 for controlling the control unit 130.

First, the sintering bogie 40 has a bottom surface and sidewalls extending in the vertical direction from the bottom surface on both sides of the bottom surface, and a space for loading the sintering blend material is formed by the bottom surface and both sidewalls. A plurality of sintered bogies 40 are continuously connected to each other to circulate along the movement path 55. The sintered bogie 40 is moved along the moving direction of the saddle bogie 40 to open a space in the sintered bogie 40, Thereby forming a ring-shaped space. The sintered bogie 40 thus formed is provided with a wheel at a lower portion of the bottom surface to move along the movement path 55. When passing through the upper portion of the movement path 55, When passing through the area, a bottom surface may be provided on the upper part.

In the upper region of the movement path 55 of the sintering bogie 40, the material is charged, ignited, sintered and cooled in the sintered bogie 40 to a region where the sintered light is substantially produced. And the lower region of the movement path 55 is a rotation period for moving to the upper region. And an area that is changed from the upper area to the lower area is a light distribution part in which the sintered light produced in the upper area is shined.

The upper region of the movement path 55 of the sintering bogie 40 is provided with a raw material loading region for loading the raw material into the sintering bogie 40 on one side and the ignition region and the sintering region along the traveling direction of the sintering bogie 40 And a cooling section. The ignition section is provided with an ignition furnace (30) to ignite the surface layer portion of the raw material layer of the sintered bogie (40). The sintering zone is a region where sintered light is produced by sintering from the surface layer portion to the lower layer portion of the ignited raw material layer by sucking the raw material layer in the wind box 10 below the sintering carriage 40. The cooling section is a region where the sintered ores produced in the sintering section are cooled by suction through the wind box 10.

The magnetizing apparatus 100 will be described with reference to Figs. 3 and 4. Fig.

The electromagnet 110 may be provided on at least one side of the movement path 55 on which the sintering bogie 40 moves and may be provided on both sides of the movement path 55 in order to effectively suppress the generation of the residual light. The electromagnet 110 may be arranged so as to face the outside of the sintered bogie 40, for example, both sides. The electromagnets 110 may be disposed along the longitudinal direction of the sintered bogie 40 so as to have a predetermined height in the height direction of the sintered bogie 40, For example, the electromagnet 110 may be formed over the entire height of the sintered bogie 40, or may be formed over a part of the height of the sintered bogie 40. In the latter case, it may be formed in a height direction of the sintered bogie 40 from the bottom to a half area. This is because the sintered light can be fused at the lower side of the sintered bogie 40 because the lower side of the sintered bogie 40 has a larger amount of heat than the upper side in the process of manufacturing the sintered ores.

The electromagnet 110 may be continuously disposed over the entire cooling section in the moving path 55 of the sintered bogie 40 as shown in Fig. 5 (a). Alternatively, as shown in FIG. 5 (b), a plurality of electromagnets 110 may be provided spaced apart over the entire cooling section. Here, it is described that the electromagnet 110 is formed over the entire cooling section, but it is needless to say that the electromagnet 110 may be formed in a part of the cooling section.

The power supply unit 120 provides power for operating the electromagnet 110.

The control unit 130 may control the operation of the power unit 120 to control a pattern of a power source provided to the electromagnet 110. For example, the control unit 130 may control the power supply unit 120 to supply or cut off the power to the electromagnet 110 in a predetermined pattern, or may control to supply or cut off power to the electromagnet 110 in an irregular pattern. This will be described later.

With such a configuration, the magnetizing apparatus 100 can generate vibration in the sintered orbital by repeatedly or intermittently releasing magnetization and magnetization of the sintered org.

The electromagnet 110 can repeatedly turn on and off the sintered bogie 40 while moving the sintered bogie 40 repeatedly to magnetize and magnetize the sintered bogie 40. When the electromagnet 110 is turned on, sintered light in the sintered bogie 40 is magnetized to generate attraction between the electromagnet 110 and the sintered light. When the electromagnet 110 is turned off, the magnetization of the sintered body in the sintered bogie 40 is released. As described above, the magnetization and magnetization of the sintered ores are released repeatedly or intermittently, which causes vibration in the sintered ores. Cracks in the sintered light can be generated through the vibration generated in the sintered ores and the sintered light adhered to the inner wall of the sintered bogie 40 can be separated from the inner wall of the sintered bogie.

Hereinafter, a method of treating a raw material by using the above-described raw material processing apparatus, for example, a sintered light producing method will be described.

The method for producing sintered ores according to an embodiment of the present invention includes the steps of preparing a raw material for sintering (S110), filling a sintered raw material into a sintering bogie (40) to form a raw material layer (S112) A step of sintering the raw material layer in the sintered bogie 40 to produce an sintered light; a step of cooling the produced sintered ores; and a step of distributing the sintered ores. In the process of cooling the sintered ores, And releasing magnetization and magnetization repeatedly to generate vibration.

The upper light is supplied to the upper light hopper 10, and a raw material for sintering is prepared by supplying the sintered raw material including iron ore and solid raw material to the waste hopper 20.

Thereafter, a plurality of sintering carts 40 are sequentially passed to the lower side of the upper light hopper 10 and the surge hopper 20, and the upper light and the sintering material are charged into each of the plurality of sintering carts 40 to form a raw material layer. Each of the plurality of sintering bogies 40 sequentially passes under the ignition furnace 30 while a flame is ignited on the surface layer of the raw material layer and each sintering bogie 40 is conveyed by the conveying device 40 in the direction of the light- At this time, the respective sintering bogies 40 sequentially pass over the upper side of the plurality of wind boxes 70 arranged in the sintering section. The raw material layer is sintered from the upper part to the lower part in the sintering section, and the heat of the upper part is transferred to the lower part, so that the overheating phenomenon may occur in the lower part. So that the sintered light can be fused to the inner wall of the sintered bogie 40 on the lower side of the sintered bogie 40.

In order to separate the sintered light fused to the inner wall of the sintering bogie 40 from the inner wall of the sintering bogie 40, the sintered light in the sintered bogie 40 may be vibrated in the cooling section of the sintered light. When the sintered bogie 40 manufactures sintered light in the sintering zone, the magnetization apparatus 100 generates vibration in the sintered barrel 40 in the cooling zone.

Generation of vibration may cause vibration in the sintered light by repeatedly or intermittently applying and interrupting power to the electromagnet 110 provided in the movement path 55 of the sintered bogie 40. [ That is, when power is applied to the electromagnet 110, the sintered organs are magnetized, and an attractive force is generated between the electromagnet 110 and the sintered organs. When the power applied to the electromagnet 110 is cut off, the attraction between the sintered light and the electromagnet 110 is removed.

The magnetization of the sintered ores and the release of the magnetization can be continuously performed over the whole of the cooling section as shown in Fig. 6 (a). That is, the magnetization of the sintered ores and the release of magnetization can be repeatedly performed at regular intervals in the entire cooling section. Alternatively, as shown in Fig. 6 (b), it can be repeatedly performed at irregular intervals in the entire cooling section. In this case, the magnetization of the sintered ores and the release of magnetization can be repeated at short intervals for a predetermined period, and then the magnetization and the magnetization can be released repeatedly at relatively long intervals. Such a pattern can be repeated one or more times throughout the entire cooling section.

As shown in FIG. 6 (c), the magnetization and magnetization are released repeatedly at a relatively long interval at the beginning of the cooling section, and the magnetization and magnetization are released repeatedly at a short interval . Alternatively, magnetization of the sintered ores and release of magnetization may be performed in the opposite pattern.

5 (b), even if power is applied to the electromagnet 110 at a constant interval, the magnetization of the sintered ores and the magnetization of the sintered organs are released in the cooling section Can be performed intermittently.

If the process of magnetizing the sintered ore and releasing the magnetization is repeatedly performed, vibration occurs in the sintered ore. When vibration occurs in the sintered ores, cracks are generated in the sintered ores, and sintered light welded to the sintered bogie 40 can be separated from the inner wall of the sintered bogie. Accordingly, when the moving direction of the sintering bogie 40 is changed for the light distribution, that is, when the sintered bogie 40 moves downward from the upper region of the movement path 55, the sintered light in the sintering bogie 40 can be distributed to the light distribution portion.

In the course of the movement of the sintered bogie 40, the sintered light in the sintered bogie 40 is vibrated, thereby facilitating the distribution of the sintered light. Therefore, since it is possible to suppress the generation of the residual light in the sintered bogie 40 after the light distribution, it is not necessary to stop the operation to remove the residual light, and the decrease in the productivity can be suppressed. In addition, since it is not necessary for the operator to directly remove the residual light in the sintering bogie 40, the burden on the operator can be reduced, and safety accidents that may occur due to the residual light removal can be prevented.

Although the present invention has been described in connection with certain exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Therefore, the scope of the present invention should not be limited by the described embodiments, but should be defined by the appended claims and equivalents thereof.
