Description

Automatic Spectral Removal Device of Great Bar

The present invention relates to a device for automatically removing the spectra of the grate area of the Great Bar, and more specifically to the spectrometer embedded in the pore area of the Great Bar so that the suction air flow required for the downward suction sintering operation is not blocked. The present invention relates to a device for automatically removing spectroscopy of a great bar gap to prevent abnormal abrasion of the great bar.

In general, as shown in FIG. 1, in the sintering operation performed in the sintering machine 100 of a steel mill, first, a top bar having a particle size of 10 to 15 mm filled in the upper hopper 110 is a great bar of the trolley 120. The trolley 120 is loaded with a thickness of 30 to 50 mm on top of each other and a blending raw material in which various raw materials and fuel coke are blended in a surge hopper 130. When charged to be 580 to 630mm thick in, when the trolley 120 with the compounding material is pressurized when passing through the ignition furnace 160 while traveling along the running rail 150, the coke included in the compounding material is ignited , The compounded blended raw material is connected to two blowers 190 to perform a downward suction type sintering method for forcibly inhaling air from above to downward as a wind box 170 installed in two rows with a cylindrical blower 180. Therefore, from the upper layer to the lower layer of the blended raw material Firing is performed while conducting heat, and a product in which the blended material is calcined and compacted is called a sintered ore.

In addition, in the light distribution unit for distributing the sintered ore, the trolley 120 is separated from the sintered ore by endless orbital movement along the running rail 150, and the separated sintered ore is subjected to crushing and sorting with an appropriate particle size of 5 to 50 mm. It is then charged to the blast furnace bin 210 by a belt conveyor, which is a transportation facility, this series of processes is called sintering operation.

In this case, in the downward suction type sintering method as described above, the charging chute 140 and the ignition furnace 160 are in position, and the bogie 120 moving at a speed of 2 to 5 m / min from the raw material loading part to the light distribution part. Charge the raw material on the Great Bar 122 of the ignition, and at the same time sintering by sucking air from the bottom of the Great Bar 122, and discharges the sintered ore while the cart 120 is reversed in the light distribution unit, This method has the advantage of being able to mass-produce by continuous operation, but due to the density deviation of the charged raw materials, the knitting is generated in the air sucked in a certain amount so as to be fired, resulting in uneven quality of the sintered ore. There was a problem such that the great bar 122 of the cart 120 is abnormally worn.

That is, as shown in FIG. 2, the cart 120 employed in the downward suction sintering method includes an insulation piece on which the main body 121 and the plurality of great bars 12 are placed. 123, sidewalls 124 fixed to the locking pin 124a, a plurality of running wheels 125 mounted on the running rails 150, and a seal bar on the wind box 170. As the wear plate 126 is fitted to the 126a), between the great bars 12 fitted to the insulation piece 123, the blending material is sintered from the top to the bottom to be fired. A void is formed which can inhale air.

In this case, when 3 to 5 mm ore having an irregular shape and size is charged into the cart 120 to irregularly block the pores of the great bar 122, the amount of air supplied from the upper layer of the sintering machine 100 is greater than the great bar ( 12) is made into the gap portion of the air gap flows into the lower layer portion, and since the flame forward speed is different from each other in the same image area of the sintering machine 100, non-uniform plasticity is achieved.

This is because when the pore of the Great Bar 122 is normal, the charging density is lowered, so that the inflow of air, that is, the ventilation is reduced, and the amount of passage of air is increased, the flame forward speed is increased, and the holding time at the highest temperature is reduced, so that the plasticity is reduced. On the other hand, if the charged ore is filled in the air gap of the Great Bar 122 as described above, the charge density increases and the flow rate of the air flow decreases, the flame propagation speed becomes slow, and the holding time of the maximum temperature is long. This results in a slower firing. In this way, the sintered ore is non-uniformly produced by the firing time difference between the easily vented portion and the non-permeable portion. Since the sintered ore which is fired quickly is rapidly quenched on the trolley 120, the sintered ore having low strength is produced, and the growth of recrystallized grains is inhibited by the rapid cooling of the sintered ore, and the slag component is glass. There was a problem that the spectroscopy could not be generated.

Therefore, the present invention has been devised to solve the problems described above, the purpose is to automatically remove the spectra filled in the pores between the grate bar to uniformly inhale a certain amount of air required for the sintering operation downward, By minimizing the suction resistance to uniformly sinter the blended raw materials on the trolley to improve the quality and output of the sintered ore, and to provide an automatic spectroscopic removal device of the Great Bar voids that can reduce the abnormal wear of the Great Bar.

Automatic spectroscopic removal device 1 according to the present invention, as shown in Figures 4 to 6, is continuously driven along the running rail 150 to complete the light distribution, and then directly to the lower side of the bogie 120 for return operation The roll member 34 is installed so that the power obtained by the pulley 12 rotating in contact with the great bar 122 traveling in one direction is automatically removed as a lever 21 to remove the spectroscopy between the pores of the great bar 122. By hitting the up and down) iso to periodically hit the Great Bar 122, such a device 1 is composed of a power generating unit 10, a power transmission unit 20 and the striking unit (30).

That is, the power generator 10 generates a power for the driving while rotating in conjunction with the one-way progress of the Great Bar 122 installed on the trolley 120 circulating along the running rail 150 of the endless track during the sintering operation Is equipped with a plurality of pulleys 12 mounted on the outer peripheral surface of the cylindrical blade 11 in contact with the great bar 122, the pulley 12 is rotatably mounted between the support beam 13 facing The support beam 13 is mounted on the upper surface of the tension base 14 which is connected by a fixed base 15 and a hinge pin 14a fixedly installed and hinged.

In addition, while the pulley 12 rotates by contact with the great bar 122 traveling in one direction, the wing 11 is repeatedly formed by the hinge operation using the hinge pin 14a as the pivot axis. The screw 16 having a plurality of screws 16 penetrating and fixing the lower end to the upper surface of the fixed base 15 so as to be in contact with the tension base 14 at all times, and having a spring 16a having a constant elastic restoring force. The upper end of the (16) is fastened to the nut member (16b).

And, the power transmission unit 20 for transmitting the rotational driving force of the pulley 12 to enable the striking operation is a lever 21 of a predetermined length that is always located without the end is separated between the rotating blades (11). Equipped with a support shaft 22 which is installed in the middle orthogonal to the lever 21 and the lever 21 is connected as a fixed cover 22a, and is installed on the upper end of the opposite support 23 Since both ends of the support shaft 22 are rotatably mounted between the bearing members 23a, the lever 31 having the end caught by the rotating blade 11 at the time of rotation driving of the pulley 12 is pulley 12 The rotational motion of)) is converted into a seesaw movement in which the front end and the rear end move upside down on the basis of the connection point orthogonal to the support shaft 22, and then the frame to be described later to make the striking operation of the great bar 122. Forward to the end of 31 It is.

In addition, the striking portion 30 that strikes periodically so as to remove the spectroscopic sandwiched between the pores of the great bar 122 is the tip of the lever 21 to seesaw movement every time the contact with the blade 11 rotates in one direction Equipped with a frame 31 having a rear end axis 31b hinged at the center of the length, such a frame 31 is a pedestal 32 so that the seesaw movement in the opposite direction with respect to the seesaw movement of the lever 21 is smoothly made. The intermediate shaft is pivotally installed on the hinge shaft 32a of the front end, and a plurality of striking bars 34a on the outer surface of the front end shaft 31a that strike the great bar 122 during the ascending operation are installed on the outer surface thereof. The roll member 34 is provided, while the rear side of the frame 31 prevents the roll member 34 from falling down from the ground while adjusting the number of installations so that the impact strength by the striking bar 34a is appropriately adjusted. So that you can adjust The weight amount of the configuration equipped with a plurality of weights 33 is heavier than the weight of the roll member (34).

Referring to the operation of the automatic spectroscopic removal device of the pores of the great bar having the structure as described above are as follows.

That is, when the sintering operation is continuously driven to complete the light distribution in the light distribution unit, the end of the blade 11 installed on the outer circumferential surface of the pulley 12 is always folded to the great bar 122 of the returned bogie 120 Therefore, in the sintering operation, the pulleys 12 installed on both support beams 13 may be rotated in one direction without a separate rotational power device as well as the one-way progression of the great bar 122.

In this case, the support shaft 22 is caused by the interference by the rotation of the blade 11 in contact with the lever 21, the end of which is always located between the blades 11 of the rotating pulley 12 as shown in FIG. While the end is pressed downward with the orthogonal connection point with the pivot axis, the opposite end is raised by the seesaw operation of the lever 21. At this time, the leading end and the rear end shaft 31b of the raised lever 21 are hingedly connected, and the frame 31 mounted on the hinge shaft 32a of the pedestal 32 to enable the seesaw operation is different from the lever 21. On the contrary, as the rear end is lifted up and the tip is lowered, the seesaw operation is performed, so that the roll member 34 mounted at the front of the frame 31 can be spaced apart from the great bar 122 by a predetermined distance.

On the other hand, when the rotation of the pulley 12 proceeds and the end of the lever 21 is out of the wing 11 at any point, the lever 21 is free and at the same time, the While the seesaw operation of lowering the front end of the lever 21 connected to the rear end shaft 31a and raising the end by the weight 33 mounted on the rear side is performed, the frame 31 has the weight 33 On the contrary to the above, the rear end of the pedestal 32 is rotated by the hinge shaft 32a of the pedestal 32 by the self-weight and performs the seesaw operation of raising the tip.

In this case, when the interference between the lever 21 and the blade 11, the roll member 34 in front of the frame 31 is automatically raised to the Great Bar 122 as a striking bar 34a installed on the outer peripheral surface thereof. When hitting the lower surface of the, it is possible to automatically remove the spectra that were filled between the pores of the Great Bar 122 by the impact.

On the other hand, the hinge pin 14a of the tension base 14 is lowered to the pivot axis until the end of the lever 21 is lowered so as to compress the spring 16a fitted to the screw 16 between the fixed base 15. As the tension base 14 is lifted up again by the constant elastic restoring force of the spring 16 when the end of the lever 21 rises, the great bar 122 of the blade 11 of the pulley 12 is raised. It is always in contact with the lower surface of the) to generate a rotational power in accordance with the progress of one direction of the cart 120 to enable the striking operation of the roll member 34 for the continuous spectroscopic removal operation.

Therefore, according to the present invention, the pulley 12 rotates without a separate power device in contact with the great bar 122 traveling in one direction, the lever 21 in contact with the seesaw which rotates in contact with the rotating blade 11, and the front and rear sides. By equipping the roll member 34 and the plurality of weights 33, each of which is equipped with the striking bar 34a, on the seesaw operation frame 31, the end of the lever 21 is freed from the blade 11 Each time, the great bar 122 is periodically hit as a striking bar 34a of the rising roll member 34 to automatically remove the spectra filled in the gaps between the great bars 122, so that the distance between the raw material particles is increased. Therefore, according to the density variation of the charged raw material, a certain amount of intake air necessary for firing enables uniform air intake through the pores of the great bar 122 without the phenomenon that the conventional pyeoncheung, sintering machine (100) Same image area) It is possible to manufacture a sintered ore of uniform quality by reducing the non-uniformity of the flame forward speed in progress, and to improve the productivity of the sintered ore more than in the past, while reducing the abnormal wear of the Great Bar 122 Is obtained.
