Description

EFFECT OF SAND TRANSPORTING FOR SKIMMER IN SLAG RUNNER

The present invention relates to a sand shut-off device for the exhaust outlet, and more specifically, after slag is closed, the slag separated by SKIMMER at the opening of the next outlet is separated from the MAIN TRON THROUGH: molten iron and slag. It is related to an automatic shutoff device that blocks the exhaust port with sand so that it can be stored in a certain time and flows smoothly through the exhaust port to the slag runner. .

Conventionally, as shown in FIGS. 1 and 2, the slag separated by the skimmer 4 and the slag separated by the skimmer 4 are not blocked at the opening 3 when the outlet 1 is opened in the furnace. As the slag does not flow smoothly to the bottom, the slag accumulates in the reflowing line, which causes trouble in the starting work. Therefore, after the end of the departure and before the opening of the Chuseok-gu, the worker climbs to the upper part of the outlet cover 5 and blocks the sand contained in the sand box 15 with the tool (long shovel or angle shovel) through the outlet hole 8. A certain amount of slag is stored in the tank, and then the slag flows smoothly while removing the blocked sand in the drain.

At this time, the worker's work load is generated due to high heat and dust generated in the outlet hole 8 during operation of the exhaust outlet sand, and the risk of safety accidents caused by the gas and radiant heat generated from the surrounding cover 5. Reference numeral 2, which is not explained, is a large degree.

The present invention was devised to solve the above problems, and the blockage block to automatically shut off the discharger sand blocking method to induce smooth flow through the slag discharge hole separated by the skimmer at the opening of the exit. The object is to provide a device.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 is a perspective view of the operation of the automatic sand shutoff device of the present invention, Figure 4 is a detailed perspective view and the main cross-sectional view of the outlet sand cut device according to the present invention.

In order to achieve the above object, the present invention includes a supply unit 100 having a sand box 15 having a centrally cut one side portion at an upper rear end of an exhaust outlet cover 5; A drive unit 200 having a structure in which the air cylinder 30 and the pulleys 19 and 28 in the casing 20 which transmit power to reciprocate the main body 35 are operated by the reduction motor 24;

It is characterized in that the upper and lower sensors 12 and 18 for transmitting a signal to move the bucket 17 up and down, and the working portion 300 is mounted sensor (16, 21) for transmitting electrical signals. To provide a blocking device that is easy to block the outlet.

Referring to the supply unit 100 shown in FIGS. 3 and 4, a rectangular sand box 15 having a center cut in the upper rear end of the exhaust outlet cover 5 is fixed and at one side of the rear side of the sand box 15. Vibretta 32 for shaking the scattered sand in the box 15 is provided, and the rising sensor 18 is provided on one side of the incision 34, the electrical signal when the bucket 17 is lowered to the lower end The height of the bucket 16 and the sensor 16 is provided at the same position.

Meanwhile, as shown in FIG. 4, the air cylinder 30 of the driving unit 200 includes an air line (not shown) collecting nib 31 through which driving air is introduced, and a connecting rod between the cylinder 30 and the main body. (29) is collected. At this time, in order to facilitate the movement of the prescribed distance of the main body 35, a pair of rollers 26 are attached to both sides of the main body 35, and the reverse circuit reduction motor 24 and the reducer (driven by the button 25 on one side) (Not shown) is connected to the lower pulley 28 of the casing 20, the upper middle Middle pulley 19 is located, the V-belt (14) as a connecting medium of the two pulleys (19, 28) in the casing (20) Is used.

In addition, the sliding part 33 is mounted on the side of the V belt 14 so that the bucket 17 can be easily moved up and down, and the front of the sliding plate 33 supports the weight of the bucket 17. The rotating shaft 40 is provided, and the bucket support pin 22 is attached to the rear side and is coupled to the support hook 23 of the bucket 17. In addition, the bucket 17 is provided with a sensor 16 for giving an electrical signal to the rising sensor 18 of the sand box 15 and a sensor 21 for giving an electrical signal to the falling sensor 12, the bucket 17 The bucket support hook 23 is attached to the bucket 17 to prevent the rotation of the bucket 17, and the bucket inclined pin 13 for inclining the sand of the bucket 17 into the exhaust hole 8 has a casing ( 20) It is located on one side of the upper part.

Hereinafter will be described the operation of the present invention.

First, sand is transported by a bucket (not shown), which is a columnar equipment, and the sand box 15 is pressed and the start push button 25 is pressed to reduce the motor 24 to operate in a forward rotation. Is always the bottom of the cut-out portion 34 of the sand box (15). When the granulated sand is contained in the bucket 17 by a worker who is waiting, a middle speed pulley 19 in which a speed reducer (not shown) coupled with a reduction motor 24 is connected by a motive pulley 28 and a belt 14 is provided. At the same time, the sand bucket (17) of the sliding plate 33 attached to the belt 14 is rotated forward.

At this time, when the bucket 17 is raised and the sensor 16 attached to the bucket 17 sends an electrical signal to the rising sensor 18, the rising sensor 18 moves forward of the air cylinder 30 (not shown). When the cylinder 30 is advanced by operating the main body 35, the main body 35 is moved to the outlet hole 8 by the connecting rod 29 connected to the main body 35, and the raised bucket 17 has a bucket tilt pin. (13) is inclined (see Fig. 4-1), the sand carried in the bucket 17 is introduced into the outlet hole 8 to block the outlet port (3). Here the inclination pin 13 is installed to match the working position.

At this time, when the sensor 21 attached to the bucket 17 gives an electrical signal to the lowering sensor 12 attached to the casing 20 while the inclined sensor 12 is lowered, the cylinder 30 moves backward. The main body 35 is reversed and the bucket 17 is lowered by the reverse rotation of the reduction motor 24 at the same time, and the lowered bucket 17 is in contact with the incision of the sand box 15. Bucket support haka 23 attached to (17) is caught by the slide plate 33 and the bucket support pin 22 attached to the bucket 17 is in place. At this time, the vibrator 32 decayed in the sand box 15 is installed to prevent the attachment of sand to the sand box (15).

The present invention allows the operator to shut off the exhaust outlet with sand to protect the water supply from the slag flowing from the exhaust outlet during the opening of the exit in the blast furnace. It provides the effect of reducing the risk of accidents and workload.
