Description

Top light charging device of sintering machine which can be separately charged by particle size {AN APPARATUS FOR CHARGINH BED ORES INTO A SINTERING MACHINE}

The present invention relates to an upper light charging apparatus of a sintering machine capable of separating and loading each particle size so that when the upper light is charged into the sinter in the sintered ore manufacturing process of the steel mill, the upper light can be separated by particle size and sequentially loaded into the sintering machine. In particular, when charging the sintering machine of the top light for the sintering process, by inserting the top light with a small particle size in the top light having a high particle size from the bottom of the sintering machine according to the particle size of the top light, the breathability of the sintering machine At the same time, it is possible to control the air permeability of the sintering machine by controlling the mixing state of the upper light charged according to the ventilation pressure, thereby improving the productivity of the sintering process. It is about.

1 shows a sintered ore manufacturing process used in the blast furnace operation in the steel mill as a process flow diagram.

That is, as shown in Figure 1, in the raw material storage bin 100, the primary mixer by cutting out the iron ore of less than 8mm and the secondary materials such as limestone, silica, serpentine, and the like, fuel coke, anthracite, etc. At 101, while adjusting the appropriate moisture, that is, about 6 to 7% of moisture, at the same time, pseudo-incorporation, that is, the fine particles of less than 1mm is attached around the nuclear particles of more than 1mm,

Subsequently, in order to improve the strength of the coarse granulated raw material incorporated in the secondary mixer 102, mixing is performed between the raw materials and then stored in the surge wave 103 using a belt conveyor.

Next, the blending raw material 116 stored in the surge hopper 103 is charged to the sintering machine 106 through the drum feeder 120 to ignite the upper surface due to the combustion heat of air and coke oven gas (COKE OVEN GAS) In addition, the sintered ore is manufactured by melting and reducing air while sucking air into the exhaust gas pipe 112 through the approximately 25 wind phases 111 provided in the downward direction of the sintering machine 106.

Then, the sintered ore thus prepared is charged into the primary crusher 107 as a sintered compact, crushed to a size of 250 mm or less, sent to the cooler 108, cooled to an appropriate temperature, and then in the secondary crusher 109. After being crushed again at an appropriate granularity of about 5-50 mm, the sintered ore that is added or sorted to the blast furnace work after the sorting operation through the sorting machine 100 is sent back to the surge hopper 103.

In this case, reference numeral 105 is an ignition furnace, 113 is a combustion gas dust collector, 112 is a blower, and 115 is a stack.

On the other hand, in the sorter 110, the sintered ore having a particle size of about 5-50 mm is introduced into the blast furnace, and the particle size of about 8-13 mm is selected and the upper optical hopper 104 installed below the surge hopper 103. Will be sent.

Then, the top light 117 emitted from the top light hopper 104 is charged with a predetermined thickness on the bottom side of the sintering machine 106, as shown in Figure 2, and then the raw material 116 is charged thereon The upper light 117 is to maintain the air intake through the wind phase 111 by the blower 113 during the sintering operation, that is, to maintain the air permeability of the sintering machine 106. Since the air permeability cannot be maintained when charged into the bottom of the sintering machine 106, that is, the great bar (not shown), the sintering machine 106 is provided with the upper light 117 having particles of about 8-13 mm which have undergone the sintering process as described above. The top light 117 is charged to about 10% of the height of the sintering machine.

However, during the initial sintering operation, there is no manufacture of the upper light, so that the raw material is charged into the sintering machine 106 in a low layer to sinter the state to maintain a certain degree of breathability, and then the upper optical hopper 104 through the sorting operation. When the upper light 117 is stored in the sintering machine 106, the upper light 117 and the compound material 116 is charged in order to ignite the ignition furnace 105 to perform the sintering operation.

However, as shown in FIG. 2, when the upper light 117 is charged to a predetermined thickness over the great bar of the sintering machine 106 through the discharge feeder 121 in the upper optical hopper 104, the surge hopper 103 is then loaded. In order to charge the blending raw material 116 as a drum feeder 120 to the sintering machine 106, the upper light 117 having a particle size of about 8-13mm is charged in the state that is not separated by the particle size, Segregation is not working properly.

Therefore, according to the conventional charging of the sintering machine of the upper light, the upper light of the fine particles (117a), small particles (117b) and neutral (117c) is mixed to be charged in the mixed state without vertical segregation in the sintering machine 106, When the fine particle upper light 117a is charged close to the side of the great bar, there is a problem that the air passage between the great bars installed at intervals of about 5 mm is reduced, that is, the air permeability is reduced.

As a result, the sintering ore is unevenly fired due to poor breathability during the sintering operation, or the unbaked sintered ore is discharged as it is in the post process, so that a large amount of cooling air is required, and a fire may occur during conveyance of the belt conveyor. There is.

On the other hand, although not shown in the drawings, there is a conventional technique for separating the particle size using a slit bar (not shown) to the upper light 117 in order to solve the problem caused when charging the sintering machine of the upper light, In practice, the particle size separation of the upper light by the slit bar is significantly less efficient.

Therefore, when the top light 117 of the sintering machine 106 is charged when the top light, which has been separated into fine, small, and neutral particles, is charged into the sinter in the order of neutral, fine, and small particles through a separate chute, sintering It would be desirable to improve the air permeability of the group.

SUMMARY OF THE INVENTION The present invention has been made to solve various problems of the prior art, and its object is to obtain the top light as a multi-stage particle size separating roll from the top light storage hopper to the sintering machine. After sintering, the sintering can be separated by particle size to improve the air permeability of the sintering machine by sequentially charging the top, light, neutral, fine, and small particles from the great bar side of the sintering machine through the chute for each particle size. It is to provide a top light charging device of the machine.

In addition, another object of the present invention, by controlling the moving speed of the separation of the upper light by the particle size, by adjusting the sintering machine charging state of the upper light in accordance with the negative pressure on the sintering machine, as well as improving the air permeability of the sintering machine, An object of the present invention is to provide an upper light charging device of a sintering machine capable of separating and charging by particle size to further improve the sintering efficiency of the sintered ore.

In the lower portion of the upper light chute 10, a plurality of discharge chutes 12 are provided to separate and discharge the upper light 117 separated by various particle sizes into the sintering machine 106, as described in detail below. .

That is, as shown in FIGS. 3 and 5, an inlet 14 through which the upper light 117 supplied from the discharge feeder 121 is introduced into the chute at one upper end of the upper light chute 10. Is integrally formed.

In addition, as shown in Figure 3, the discharging chute 12 is divided into a particle separation roll 30 is installed inside the granular secondary light (117a), small particle tube (117b), neutral upper light (117c) ), And the opposing specular light 117d are separated and charged, respectively, and are composed of fine, small, neutral, and allelic discharge chutes 12a, 12b, 12c, and 12d which are separated and discharged into the sintering machine 106. Each chute 12 will be described later, but depending on the operation of the separation roll, the fine and small particles of the upper light (117a, 117b) may be mixed with each other and inserted into it.

Meanwhile, as shown in FIG. 3, each of the upper light beams 117 is disposed below the respective discharge chutes, that is, the fine, small, neutral and opposing discharge chutes 12a, 12b, 12c, and 12d. Induction rolls 16 are installed in the sintering machine 106 for smooth and constant charging.

In addition, the upper light chute 10 of the present invention is installed to be inclined as a whole, and each of the discharge chute 12 is also installed to be inclined at the lower end to facilitate the charging of the sintering machine 106 of the upper light 117. do.

Next, FIGS. 3 to 5 illustrate the particle size separation roll 30 of the upper light charging device 1 of the present invention, and the particle size separation roll 30 of the present invention is the top light chute 10. The discharging chute 12 is installed to drive the motor 32 in an inclined direction inside the upper part of the discharge chute 12 so as to separate the upper light by a certain particle size.

4 and 5, the particle size separation roll 30 of the present invention is divided into a fine particle size separation roll 30a, a small particle size separation roll 30b, and a medium particle size separation roll 30c. The separation rolls 30 are arranged inside the discharge chutes 12a and 12d.

That is, as shown in Figures 3 and 5, the fine particle size separation roll 30a is a pair of two rows of rolls are installed above the fine grain chute (12a) and roll spacing (D1) equal to the diameter of the particulate upper light The small particle size separation roll 30b is provided with two pairs of rolls in a row above the small particle discharging chute 12b and has a roll spacing D2 equal to the diameter of the small particle top light.

In addition, the middle particle size separation roll 30c has two rows of pairs of rolls installed above the neutral discharge chute 12c and has a roll spacing D3 equal to the diameter of the neutral neutral upper light, and eventually the roll spacing D1. The upper light 117 passing through -D3) is separated into fine, small or neutral upper light.

Next, as shown in Figure 5, the particle size separation roll 30 as described above as the main chain 38 is fastened to the main gear 36 of the main drive shaft 34 that is rotated by the drive of the motor (32). The driven gears 42 installed on the driven shaft 40 and the roll gears 46 mounted on the roll shafts 44 protruding out of the chute are fastened by a connecting chain 48 to drive the motor 32. When the separation roll 30 is configured to drive.

That is, when one main drive shaft 34 is driven, the driving force is driven by the driven shaft 40 arranged on the side of each of the three pairs of separation rolls 30a, 30b, 30c provided in parallel as the main chain 38. The gears 42 and the roll gears 46 of the roll shaft 44 are transmitted as the connecting chains 48 so that a total of twelve separation rolls 30 are installed as one drive motor 32 at the same speed.

At this time, although not shown in the figure, it is also possible to drive each of the separation rolls 30a, 30b, 30c as separate drive motors, in which case each separation roll 30a, 30b, 30c. It would be more desirable because individual speed control of the

On the other hand, as shown in Figure 5, on the circumferential surface of the particle size separation roll 30 a plurality of vanes 31 for separating and moving the upper light is installed, that is, the interval of each separation roll 30, The spacing D1-D3 between the berins 31 is formed in the same size as the particle size of the fine, small and neutral upper light 117a, 117b, 117c.

That is, the above-mentioned fine, small, neutral, and opposing upper lights 117a, 117b, 117c, and 117d are separated into particle sizes of 8 mm or less, 10 mm or less, 12 mm or less, and 13 mm or more, respectively. As described above, the upper light 117 sorted by the sorter 110 to a particle size between 8 and 13 mm is charged to the sintering machine 106 more uniformly.

Of course, by adjusting the spacing of the separation roll 30 is to perform the charging 110 to the upper light 117 having a larger volume while separating by the particle size of the upper light 117.

Next, FIG. 3 illustrates the negative pressure sensor 50 of the apparatus 1 of the present invention, and the negative pressure sensor 50 of the present invention is installed on the lower wind phase 111 of the sintering machine 106 and is wound up. The air negative pressure at 111 is measured to adjust upper light emission.

That is, the negative pressure measurement sensor 50 installed in the wind phase 111 of the sintering machine 106 is installed under the motor 32 driving the particle size separation roll 30 and the upper light hopper 104. The negative pressure sensor 50 is electrically connected with the motor of the discharge feeder 121 through the control unit C, and the rotational speed of the separation rolls 30 is controlled through the control unit C according to the negative pressure in the wind box 111. It consists of a configuration that is installed to control the amount of light emitted from the top of the discharge feeder.

Referring to the operation and effects of the present invention made in the above configuration in more detail as follows.

First, the upper light 117 sorted into 8-13mm through the sorting unit 110 through the sintering process of the blended raw material 116 is charged into the upper light storage hopper 104, discharge feeder 121 installed on the lower side Through the inlet 14 of the upper light chute 10 of the present invention through the continuously inserted into the chute (10).

Next, as shown in FIGS. 3 and 5, the upper light 117 charged in the upper light chute 10 first falls to the fine particle separation roll 30a and has a fine particle size of 8 mm or less. (117a) is passed through the gap between the fine particle separation roll (30a) installed in two rows in a pair, that is, the gap (D1) between the vanes 32, when falling to the fine discharge chute (12a), the lower guide roll ( 16, the particulate upper light 117a is charged into the sintering machine 16.

That is, as shown in Figure 5, the vane 31 provided in the fine particle separation roll (30a) is the gap between the vanes (31) while inducing the upper light 117 to the upper light at the interval (D1) D1) is formed to be 8 mm, and the particulate upper light 117a of 8 mm or less of the upper light 117 is inserted into the sintering machine 106 through the discharge chute 12a.

However, as shown in FIG. 3, in the following description, the opposite sintered light 117d is first loaded into the actual sintering machine 106, and then the neutral, small, and fine top light 117c, 117b, and 117a are sequentially loaded. Since the charging is carried out in the order of), the upper light having the larger particle size is laminated from the upper light having the larger particle size, and the compounding material 116 is charged thereon, whereby the air permeability of the sintering machine is good. This is because the distance between the great bars is about 5 mm, the opposing top light 117d of 13 mm or more improves air permeability by the blower (113 in FIG. 1) by that much.

Next, as shown in FIG. 3, the small top light 117b of 10 mm or less of the remaining top light 117 except the fine top light 117a is followed by the vane gap 31 of the next small separation roll 30b. Since it is about 10mm it is charged into the sintering machine 106 as the guide roll 16 through the small discharge chute 12b.

Next, the neutral upper light 117c of 12 mm or less of the remaining upper light except the fine and small upper light has a neutral discharge chute (123) because the vane 31 gap D3 of the neutral separation roll 30c installed next is 12 mm. It is charged to the sintering machine 106 through 12c) and the guide roll 16.

Finally, as shown in FIG. 3, the top discharge light of 13 mm or less in which the fine, small, and intermediate top lights 117a, 117b, and 117c dropped into the discharge chute does not need to go through a separate separation roll. It is charged to the sintering machine 106 through the guide roll 16 through 12d.

Meanwhile, as shown in FIG. 5, each of the particle size separation rolls 30 as described above is driven by the main chain 38 fastened to the main gear 36 of the main drive shaft 34 driven by the motor 32. The driven shaft 40 is driven integrally by driving the driven gear 42, and the other driven gears 42 installed on the driven shaft 40 are connected to the roll shaft 44 by the connecting chain 48. It is engaged with the gear 46, and as a result, when the driving motor 32 is driven, the whole separation rolls 30 are integrally driven as the main and connecting chains 36 and 48. They are driven to guide and drop the upper lights toward the discharge chute 12 side facing each other.

On the other hand, as shown in Figure 3, the negative pressure sensor 50 is installed on the lower side of the air phase 111 connected to the blower 113 for air suction for the sintering of the sintering machine 106, wherein the negative pressure The sensor 50 is electrically connected to the motor 32 driving the particle size separation rolls 30 and the motor of the discharge feeder 121 of the upper light hopper 104 and the control unit C.

Therefore, when the negative pressure sensor 50 detects the negative pressure above the set value, it is determined that the air permeability of the upper light 117 and the blended raw material 116 charged to the sintering machine is less than the reference value, and the control unit C controls the driving motor 32. ), The driving speed is reduced, and the amount of light emitted from the top of the discharge feeder 121 is reduced.

That is, if the air permeability of the sintering machine is poor, the top light is not charged in the stacking order of the top light which is the most breathable, that is, in the order of opposing, neutral, small, and finally fine, for this purpose, the top light 117 Delaying the speed of the separating roll to separate the upper light 117 by the particle size by that much, and through each discharge chute 12 each of the upper light (117a0 (117b) (117c) (117d) sintering machine This is because it is charged.

On the contrary, if the negative pressure is lower than the reference value, the sensor 50 increases the speed of the drive motor 32 and the discharge feeder 121 through the control unit C, and eventually the rotational speed of the separation rolls 30 When augmented, the order of the opposing, neutral, small and fine front light 117a, 117b, 117c and 117d in front of the upper light does not pass through each of the separation rolls 30 but to the next separation rolls. As a result, it is not charged into the sintering machine 106, and the upper light of various particle sizes flows toward the opposing discharge chute 12d side, thereby reducing the air permeability of the sintering machine.

Accordingly, the negative pressure sensor 50 increases the sintering process efficiency of the sintering machine 106 by adjusting the stacking state of the top light charged in the sintering machine 106. If the air permeability is too high, the sintering time is shortened, but the sintered light On the contrary, if the air permeability is too low, the sintering time is delayed but the sintering quality of the sintered ore is good. Therefore, in the actual sintering process, it is important to perform the sintering operation for a suitable time by providing adequate ventilation. By inserting the top light separation, such breathability can be adjusted.

Of course, the measurement reference value of the negative pressure sensor 50 will vary according to various working environments of the sintering process, but in practice, the reference value of the negative pressure sensor 50 may be provided in the sintering process.

Accordingly, as compared with the conventional charging of the top light into the sintering machine without particle size separation, according to the sintering machine top light charging device 1 of the present invention, whether or not the sintering machine charged state of the top light is sequentially loaded so as to vertically segregate by the particle size, By mixing and charging the mixture, the air permeability of the sintering machine is maintained in an appropriate state to increase the work efficiency of the sintering process.

As described above, according to the inventors of the upper light charging apparatus of the sintering machine which can be separately charged by particle size, the upper light is divided into small, fine and neutral particle sizes as a multi-stage particle separation roll before the upper light is charged into the sintering machine from the upper light storage hopper. After separation, by charging the light of the neutral, fine, and small particles in sequence from the great bar side of the sintering machine through each size-specific chute, it provides the effect of improving the air permeability of the sintering machine.

Furthermore, by controlling the moving speed when the upper light is separated by particle size, by adjusting the sintering machine loading state of the upper light in accordance with the negative pressure in the sintering machine wind, the air permeability of the sintering machine is improved, as well as having a proper air permeability, It is to provide an excellent effect of further improving the sintering efficiency of the sintered ore.

While the invention has been shown and described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit or scope of the invention as set forth in the claims below. I would like to know that those who have knowledge of this can easily know.
