Description

Seal bar automatic calibration device of sintering machine bogie

The present invention relates to a seal bar installed in a lower part of a sintering machine bogie used in a sintering ore manufacturing process of a sintering plant. In particular, the inner spring of the seal bar has a problem that the inner spring is poor due to the mixing of foreign matter or grease. It relates to a seal bar automatic calibration device for a sintering machine bogie.

In general, the sintering operation refers to a series of processes that allow the overmolded blended raw material (hereinafter referred to as sintered ore) to be used in quadrants and blast furnaces. In the sintering operation, as shown in FIG. The sintering machine trolley 100 which is continuously arranged on the running rail 102 formed long in the direction is rotatably mounted by the operation of the traveling wheel 104, and various raw materials are provided on the bottom surface of the sintering machine trolley 100. And a traveling rail 120 into which the compounding material 110 mixed with fuel is charged by the charging device 115, and the compounding material 110 can be compacted on the upper part of the traveling rail 120. The high temperature ignition furnace 130 is provided.

Therefore, the blended raw material 110 is ignited while passing through the high-temperature ignition furnace 130 by the sintering machine trolley 100 in a state seated on the running rail 120, the sintering machine trolley 100 proceeds. This compacted sintered ore 135 becomes a fuel that can be used in the blast furnace A.

In addition, the lower portion of the ignition furnace 130 for igniting the blended raw material 110 during the sintering operation process, the fall-shaped wind box 141 used as a passage through which air is supplied, and the air blowing device 143 formed in communication with each other. The blower 140 which pressurizes air through the medium is provided.

By the way, the downward suction sintering method has the advantage that it is possible to mass-produce by continuous operation, but because the leakage caused during the blowing process injecting air adversely affects the quality and production of the sintered ore 135, leakage suppression is Most important of all, there was a difficulty in the operation due to the prevention of leakage.

On the other hand, as shown in Figure 2 in order to prevent leakage in the downward suction sintering method, the blended raw material 110 is a sintered ore 135 is agglomerated by a downward suction sintering method that blows air at the bottom Since it is transported to the blast furnace (A), the sintering unit sintered with the wear ring bar 142 and the sliding part of the wind box 141, which is a fixed part, in order to prevent air from being sucked in the sintering machine trolley 100 except for a gap with the running rail 120 The seal bar 145 is inserted into the contact portion of the expected vehicle 100, and the seal bar 145 has a structure in which a grease injection device 146 is provided in communication.

In addition, a spring 148 is inserted between the seal bar 145 and the seal bar case 147 in which the seal bar 145 is incorporated, and the seal bar 145 is caused by the elastic force of the spring 148. Has a structure that allows entry and exit from the seal bar case 147.

Therefore, the bottom surface of the seal bar 145 is in close contact with the wear ring bar 142 by the elastic force of the seal spring 148 to perform the sintering operation in a state where airtightness is maintained.

However, when the running rail 120 slides by forcibly injecting grease into the pipeline of the grease injection device 146 for smooth sliding of the seal bar 145, the inside of the seal bar case 147. Foreign matters such as grease or finely sintered ore are sucked in and cause a failure in the vertical operation of the spring 148 embedded in the seal bar 145 so that the seal bar 145 enters the seal case 147. As a result, a space is generated between the seal bar 145 and the wear ring bar 142. Such a leak is difficult to work during operation, so it is difficult to wait for regular repairs, and the unbalance on the sintering machine bogie 100 accompanying the leak causes adverse effects on the operation failure of the sintering work and the quality production and pollution. There was this.

The present invention has been devised to solve the problems described above, by applying a physical blow to the seal bar using the driving force of the sintering machine bogie being driven to give a pole to the seal spring to operate the spring in a steady state. It is an object of the present invention to provide a seal bar automatic calibration device for a sintering machine bogie that can be returned to the furnace.

The present invention for achieving the object as described above, in the seal bar automatic calibration device of the sintering machine bogie consisting of a structure in which the sintering machine bogie to transfer the compounding material to the running rail formed in the longitudinal direction is rotatably mounted. In the main frame provided in the transverse direction on the side of the sintering machine bogie, a rotational roll equipped with bearings is connected and the shaft is inserted in the inner circumferential surface of the rotational roll in parallel with the conveying direction of the sintering bogie. On one side of the shaft, a cam plate for securing the free fall distance generated in the press roll when the sintering machine cart is moved is fixed, and an adjustment plate for increasing or decreasing the free fall distance between the main frame and the cam plate is fastened. While it is fixed by means of means, on the other side of the shaft A striking roll is fixed to the cam plate at a right angle so that the striking bar can be smoothly seated. A weight having a predetermined weight and a fixing plate to which the weight is fixed are provided.

Therefore, by mounting the seal bar automatic calibration device of the sintering machine truck having the above-described structure, the seal bar is periodically hit automatically to stimulate the spring embedded in the seal bar and the seal bar case so that the seal bar operates normally. As the airtight state between the wear ring bars becomes good, the defective seal bar is automatically adjusted during operation to prevent leakage, and uniform firing is possible in the process of firing, thereby reducing the manpower loss hitting the seal bar. The dust concentration in the exhaust gas is reduced to reduce air pollution and to extend the life of the sintering machine and the ventilation line.

In the main frame 20 provided in the transverse direction on the side of the sintering machine trolley 12, a rotational roll 21 with a bearing is connected and provided on the inner circumferential surface of the rotational roll 21 for the sintering machine. The shaft 30 is inserted and installed in parallel with the conveyance direction of the trolley 12. On one side of the shaft 30, a free fall distance generated in the press roll 41 when the sintering machine trolley 12 moves is obtained. Cam plate (40 Is fixedly installed at the same time between the main frame 20 and the cam plate 40, the adjustment plate 42 for increasing or decreasing the free fall distance is fixed through the fastening means 43, while the shaft ( On the other side of the 30 is a striking roll (50) fixed to the cam plate (40) at an angle to the striking roll (50) for hitting the seal bar (51) for smoothly sliding the running rail (10), the striking Between the front of the roll 50 and the main frame 20, a weight 61 having a predetermined weight and a fixed plate 60 to which the weight is fixed so as to increase the thrust force when the seal bar 51 is hit. ) Is installed.

On the other hand, the cam plate 40 is installed on the adjusting plate 42 so as to increase the falling force is a structure that is fixed through the fastening means 43.

In addition, the other side of the shaft 30 is mounted a blow roll 50 for hitting the seal bar 51 of the sintering machine trolley 12 in the horizontal direction, the blow roll 50 is the shaft 30 It is fixedly installed in a direction perpendicular to the, and has a structure fixedly installed at an angle with the cam plate 40 provided in the opposite position.

In addition, the striking roll 50 is a roller type in order to minimize the frictional resistance generated at this time, since the sintering machine bogie 12 with the seal bar is moved horizontally when the seal bar 51 is struck. It is configured to be rotated when the contact with the seal bar 51 after the strike, and the hitting roll 50 is fixed to the fixed plate 60 to increase or decrease the hitting force when hitting the seal bar 51 The weight 61 having a predetermined weight is provided.

Hereinafter, the operation of the present invention will be described.

First, the sintering machine cart 12 is charged along the running rail 10, the compounding material is charged by the charging device, and then ignited by the ignition furnace and fired through downward suction to be compacted into the sintered ore. The compacted sintered ore is distributed to the blast furnace process, which is the next process, according to the running of the vehicle 12, and the sintering machine 12 is in an inverted state to proceed along the running rails 10. Will repeat.

While the sintering machine cart 12 is in an inverted state during the process, grease is deposited on the seal bar 51 itself or foreign matter such as finely divided sintered ore is mixed into the seal bar case to operate the spring stored therein. In operation, the press roll 41 is brought into contact with the cam plate 40 when the sintering machine cart 12 passes through the place where the Silva automatic straightening device is installed.

At this time, as the cam plate 40 is raised, the cam plate 40 is converted into a linear motion by drawing a circular arc roll by a linear traveling force of the press roll 41 to generate a falling distance to lift the striking roll 50 of the seal bar. When the cam plate 40 is removed from the press roll 41, the cam plate falls to the highest height and at the same time, the blow roll 50 connected to the opposite side of the shaft 30 is also dropped at the same time to the seal bar 51. Physical blow is done.

Then, the next press roll 41 is to contact the cam plate 40 to repeat the above process.

Here, the rising of the hitting roll 50 is such that the shaft 30 installed on the rotating roll 21 mounted with the bearing is rotatable so that the cam plate 40 is brought into contact with the other side when it is raised to the highest height. The installed blow roll 50 is to be raised to the highest height.

At this time, the press roll 41 of the sintering machine trolley 12 has an interval between rolls of 760 mm, and the 156 sintering machine trolleys 12 proceed continuously, so that the above-described calibration work of the seal bar 51 is performed. The straightening and lowering operation of the striking roll 50 is to continue the corrective work of the seal bar (51).

On the other hand, in order to increase the falling distance between the hitting roll 50 and the press roll 41, the distance between the shaft 30 and the cam plate 40 must be made far, and in order to adjust the distance close to reduce the falling distance. Since the striking roll 50 is configured to be able to add or subtract the weight 61 mounted on the striking roll 50 to increase or decrease the force exerted momentarily upon striking the seal bar 51, The distance of the cam plate 40 and the weight 61 of the striking roll 50 can be adjusted according to the defective degree of the bar 51.

Therefore, the spring embedded in the seal bar case is stimulated by the automatic calibration of the seal bar 51 by the hitting roll 50, so that foreign matters caught between the seal bar 51 and the seal bar case are removed. Since the spring is smoothly acting and the seal bar 51 is normally operated accordingly, the seal bar 51 and the wear ring bar are in close contact with each other, so that the airtight state is maintained.

In addition, the hitting roll 50 is equipped with a bearing so as to be rotatable, the time to contact the seal bar after hitting the seal bar 51, that is, the press roll 41 of the next sintering machine cart 12 is The rotation of the striking roll 50 is prevented from being pulled on the seal bar 51 until it comes in, and minimizes the shock absorption and noise generated when the striking roll 50 strikes the seal bar 51. It is made of rubber material.

As described above, by mounting the seal bar automatic calibration device of the sintering machine bogie according to the present invention, the seal bar is periodically hit automatically to stimulate the seal ratio and the spring embedded in the seal bar case so that the seal bar operates normally. As the airtight state between the seal bar and the wear ring bar becomes good, the defective seal bar is automatically adjusted during operation, preventing leakage and allowing uniform firing during the firing process, thereby reducing the manpower loss hitting the seal bar. In addition, the dust concentration in the exhaust gas is reduced to reduce the air pollution and has the effect of extending the life of the sintering and exhaust line.
