The present invention relates to a condensation coal removing device of the inner wall of the hopper that can safely and easily remove the condensed coal attached to the inner wall of the hopper to prevent operation delay, improve work productivity, and can always maintain a constant loading amount.

In general, coal charged in steelmaking facilities, such as coke ovens, is dried to 6% of coal with a moisture content of 9% to reduce fuel costs, and then stored in a warm state where steam is generated. Coal mining in the hopper (100).

In the process of repeating the same function about 88 times a day for about 8 minutes, the residence time of the coal stored in the hopper 100 is condensed on the inner wall of the hopper 100 in which water vapor is generated, including water, and the hopper again. When coal is stored in (1), condensed coal is generated on the inner wall of the hopper 100 continuously by the condensed water vapor and occupies the inner space.

In such a state in which condensed coal is generated, the coal is crushed into the hopper 100 from a charging hopper (not shown), and the coal is injected into the hopper 100 by the volume of the condensed coal attached to the inner wall of the hopper 100. As a result, it was not possible to supply to the target charging amount in the post-process, thereby providing a cause such as a decrease in utilization rate.                         

Therefore, in the conventional method of treating condensed coal attached to the inner wall of the hopper 100, as shown in FIG. 1, the electric hammer 109 is provided on the lower outer peripheral surface of the hopper 100 to provide a vibration source during power supply And, by controlling the operation of the controller 103 is connected to the electric hammer 109 and the cable 104 to supply power by using a remote controller 105 from a long distance, the vibration in the lower portion of the hopper 100 Was added to remove the condensed coal. However, although the removal of condensed coal from the inner wall of the hopper 100 was performed well at the beginning of operation, the condensation of water vapor gradually widened as time passed, and later, the electric hammer 109 was installed to directly contact a part of the condensed coal. Only removed and the rest not removed.

In addition, as another method for preventing condensation of water vapor in the hopper 100, a heating wire 106 is provided on the inner wall of the hopper 100 to provide a heating source when power is supplied, and the heat insulating material 110 is disposed therein. As a result, the heating wire 106 was turned on to apply heat to the hopper 100 to prevent condensation of water vapor. However, by further increasing the temperature difference with the outside, water vapor was further generated, which caused more condensed coal.

Then, in order to remove it again, the worker has to take time from time to time to tap the outer surface of the hopper 100 as a hand hammer or remove condensed coal from the opened upper portion of the hopper 100.

As the manual work is performed on the hopper of the height, the risk of safety accidents such as a worker's fall accident is very high, and the lower side coke oven is opened through the open gate 1027 when the work delay takes a long time to remove the condensed coal. While the smoke generated from the facility is leaked to the upper part, there is also a risk of a stenosis accident when an operator rushes the cylinder member 128 to seal the empty gate 127.

Therefore, the present invention has been proposed to solve the conventional problems as described above, the object of which is that the condensed coal attached to the inner wall of the hopper so that the target loading amount of the hopper is always maintained more than the occurrence of the safety accident of the operator The present invention aims to provide a condensate bomb removal device of the inner wall of the hopper that can be easily removed and removed.

The operation and effects of the present invention having the configuration as described above will be described.

The inside of the inner cylinder part 10 mounted on the inner circumferential surface of the hopper 100, which is the inner wall of the hopper 100 which is charged with coal and discharges the charged coal to the coke oven (not shown) side during the opening operation of the bin gate 107. When condensation coal is generated on the side surface, the operator operates the controller 42 by using the remote controller 41 to supply external power to the motor member 33 of the operating unit 30. The drive shaft 33a of the motor member 33 is rotated in the forward direction.

At this time, the detection hole 36b provided in the rear casing 37 is located in the vicinity of the first sensor member 38a, which is the initial position, of the inner cylinder portion 10 on which the band member 31 of a predetermined length is wound. The outer surface has an initial state parallel to the inner circumferential surface of the hopper 100 at a predetermined interval.

In this state, when the drive shaft 33a of the motor member 33 is rotated in the forward direction and the worm wheel 34 mounted at its tip is rotated, the operation belt 32 connected to one end of the belt member 31 is rotated. Since the worm 32a and the worm wheel 34, which are formed through a square hole at a predetermined interval on the outer surface, are assembled with each other, the operation belt 32 is proportional to the rotation amount of the motor member 33. It passes through the front casing 35 and starts to move horizontally in the tightening direction on the left side of the drawing.

Subsequently, as the belt member 31 is also tightened by the tightening operation of the operation belt 32, the body of the inner cylinder portion 10 having the outer surface wound thereon is retracted inward so that the outer shape is deformed. The condensed coal adhering to the inner circumferential surface of the barrel 10 can be removed by dropping down.

In addition, since the moving screw 36 is screwed to the male screw portion 36a of the drive shaft 33a which is rotated forward when the motor member 33 is rotated, the left side of the drawing when the band member 31 is tightened. The second sensor member is horizontally moved in the rear casing 37 to the right side, and the detection hole 36b of the movable screw 36 is also horizontally moved along the long hole 37a of the rear casing 37 in the same direction. It is detected at 38b.

In addition, by the detection signal of the second sensor member 37b, the rotational driving of the motor member 33 is temporarily stopped, and then made in the opposite direction to the reverse direction, thereby forming a worm wheel 34 of the drive shaft 33a. The actuating belt 32 having the worm 32a to be assembled is horizontally moved from left to right in the horizontal direction with respect to the front casing 35 fixed to the outer surface of the hopper. Accordingly, one end is connected to the operation belt 32 and the other end is connected to the hopper 100 to loosen the band member 31 that surrounds the inner body 10 and the outer body. The body is returned to the initial state inflated with the inner wall of the hopper (100).

The return operation of the inner cylinder part 10 is performed by the tension holding part 50 which always supports the belt member 31 in the outer circumferential direction. The upper and lower contact rolls 51a of the tension holding part 50 are provided. 51b is rotated in contact with the upper and lower surfaces of the band member 31 which is horizontally moved to allow tightening and loosening, while the retaining bar 52 is moved in the inner circumferential direction when the band member 31 is tightened. The spring member 53 is compressed to have elastic restoring force, and the inner member is prevented by the stopper 52b.

When the band member 31 is continuously released, the band member 31 is pushed in the outer circumferential direction in the cylindrical casing 54 by the elastic restoring force of the spring member 53. The belt member 31 connected to the tip is returned to its original state.

On the other hand, in the reverse rotational drive of the motor member 33, the reverse side in the drawing in the rear casing 37 in which the movable screw 36 screwed to the male screw portion 36a of the drive shaft 33a is fixed. At the same time as the horizontal movement to the left side, the detection hole 36b of the movable screw 36 is also horizontally moved along the long hole 37a of the rear casing 37 in the same direction and detected by the first sensor member 38a. At this time, the external power transmitted to the motor member 33 side is interrupted by the generated detection signal of the first sensor member 38a to stop the unwinding operation of the band member 31 to switch to the initial state. .

In addition, the condensed coal dropped by the tightening and releasing operation of the operating unit 30 from the inner cylinder portion 10 of the hopper 100 is temporarily accumulated in the lower portion of the hopper 100, and then the open gate 127. Discharged to the bottom through).

According to the present invention as described above, by a single worker to quickly and easily remove the condensed coal attached to the inner wall of the hopper, which is a coal storage tank, to prevent the non-combustion of the temperature difference due to work delay or charging delay In addition, this prevents the occurrence of chimney soot, while the target loading is always kept constant due to 100% removal of the condensed coal to prevent the operation rate decrease as in the prior art.

In addition, while the worker is busy during the operation, there is no need to remove the condensed coal from the upper portion of the hopper as a hand tool, thereby obtaining an effect of preventing a safety accident.

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 clarify that knowledge is easy to know.
