Description

[0001] Skirt apparatus and discharge apparatus [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skirt device and a discharging device, and more particularly, to a skirt device capable of adjusting a height of a skirt freely according to a positional error of a belt by a position and a discharging device having the skirt device.

A silo is a storage facility for storing a large amount of raw materials. In a steel mill, various raw materials are stored in a silo, and the raw materials are taken out from the silo when necessary and sent to a post-process. In this case, for example, a rotary discharge machine (RDM) is used as a device for performing the work of extracting the raw material from the silo. Al DM moves along the rail to perform the cutting operation, and the material to be cut out through the AL DM is conveyed to the post-processing by the belt conveyor. On the other hand, the parallelism between the rail and the belt is not always constant when the ALDM performs the cutting operation, and an error may occur in the parallelism depending on the section. In this case, a gap may be generated between the alumina belt and the belt as a skirt that prevents leakage of the raw material or dust from the belt, and light or dust may be generated through the gap.

However, since a conventional skirt is provided in a fixed manner or is attached to the belt at all times by its own weight due to its own weight, the fixed skirt can not prevent the occurrence of gaps, which makes it difficult to suppress or prevent scattering of light or dust And the link-type skirt has a problem that the weight of the entire skirt is always applied to the belt and wears quickly.

Techniques that constitute the background of the present invention are disclosed in the following patent documents.

The bracket 110 can be mounted by covering the upper end of the skirt 100. The bracket 110 may include, for example, a section having a cross-section of a 'C' shape, and may be coupled to the upper end of the skirt 110, for example, in a bolting manner to support the skirt 110, .

The support part 200 can be mounted to support the skirt 100. For example, the support portion 200 may be mounted on the upper surface of the bracket 110 in a vertical direction to support the skirt 100 through the bracket 110. At least one support 200 may be mounted such that two support portions 200 may be mounted such that they are equally spaced from each other in the longitudinal direction 2 at a central position in the longitudinal direction 2 of the skirt 100, .

Of course, the number of the support portions 200 to be installed is not limited to the above, and may vary. When the support part 200 is one, it can be installed at a position that can be aligned in the vertical direction 3 at the center of the lengthwise direction 2 of the skirt 100.

The supporting part 200 can be formed to be able to expand and contract in the vertical direction 3 by using the elastic force of the elastic member 260. The supporting part 200 can quickly adjust the height of the skirt 100, The impact applied from the belt 11 to the skirt 100 can be reduced and the load applied from the skirt 100 to the belt 11 can be reduced.

The supporting part 200 includes a cylindrical housing 210 such as a bush having a space 240 extending in the up and down direction 3 and a cylindrical body 210 mounted on the open bottom face of the housing 210 A lower cap 220, a disk-shaped upper cap 230 mounted on the opened upper surface of the housing 210, and an upper cap 230 extending through the upper portion of the housing 210 in the longitudinal direction 2 and extending in the vertical direction 3 A pair of openings 250 and an elastic member 260 disposed in the space 240 of the housing 210 such that the space 240 inside the housing 210 through the pair of openings 250, And the other side extends downwardly through the housing 210, the elastic member 260 and the lower cap 220 in the vertical direction 3 A flow axis 270, and a mounting ring 280 formed on the top surface of the top cap 230.

The housing 210 is a main body of the support portion 200, and an elastic member 260 may be embedded in the inner space 240. The upper cap 230 and the lower cap 220 may be mounted to cover the upper and lower surfaces of the housing 210. The height adjustment part 300 may be inserted into the mounting ring 280 and may be connected to the upper surface of the bracket 110 at the end of the flow axis 270 extending downward through the lower cap 220 .

The flow axis 270 may include a horizontal bar 272 extending in the longitudinal direction 2 and a vertical bar 271 extending downward from the center of the horizontal bar 272. The horizontal bar 272 is disposed across the lengthwise direction 2 of the interior of the housing 210 by passing the opening 250 in the longitudinal direction 2 and can be supported on the top of the elastic member 260 . The vertical bar 271 may be arranged to penetrate the housing 210, the elastic member 260 and the lower cap 220 in the vertical direction 3 and the upper surface of the bracket 110 may be mounted at the end thereof . The vertical bar 271 can be moved in the vertical direction 3 while the horizontal bar 272 is elastically supported by the elastic member 260 so that the support part 200 can expand and contract in the vertical direction 3. [ At this time, when the horizontal bar 272 moves up and down, it can be guided by the opening 250.

The elastic member 260 is compressed to a predetermined length by the weight of the skirt 100 supported by the vertical bar 271 on the other side so that the horizontal bar 272 of one side is inserted into the inside of the housing 210 As shown in FIG. Therefore, the skirt 100 can always be supported while receiving the elastic force in the upward direction by the pivot shaft 270 and the elastic member 260.

That is, the flow axis 270 is supported by the elastic member 260 built in the housing 210 and slides in the vertical direction 3 to elastically support the skirt 100. Accordingly, the weight of the skirt 100 A portion may be applied to the elastic member 260 and the remainder may be applied to the belt 11. At this time, when the gap between the belt 11 and the rail 30 is widened in the vertical direction 3, the skirt 100 descends downward while maintaining contact with the belt 11, The horizontal bar 272 can be lowered to accommodate the upward and downward movement 3 of the skirt 100 by the distance D between the horizontal bar 272 and the opening 260. When the gap between the belt 11 and the rail 30 is narrowed in the vertical direction 3, the skirt 100 is lifted upward while maintaining contact with the belt 11, and the length of the elastic member 260 The horizontal bar 272 can be raised while the skirt 100 is lifted.

The height adjusting unit 300 may be mounted to connect the supporting unit 200 and the chute 20 and may be formed to adjust the height of the supporting unit 200 by rotating the shaft.

The height adjusting part 300 is vertically coupled with the adjusting part 320 and the adjusting part 320 through the lower part of the adjusting part 320 in the left and right directions. A first height adjusting shaft 310 and a height adjusting shaft 320 which are coupled to the upper portion of the adjusting means 320 by vertically passing through a mounting ring 280 of the mounting ring 280, And a second height adjusting shaft 330 mounted on the lower surface of the upper cylinder 21 of the chute 20 on the belt conveyor 10. [

The first height adjusting shaft 310 and the second height adjusting shaft 320 are moved toward or away from each other so that the height adjusting portion 300 can move in the vertical direction 3 (h) can be adjusted. That is, the height of the skirt 100 can be adjusted to a desired height by using the height adjuster 300 and then maintained.

The height adjusting part 300 and the supporting part 200 may be aligned on the same axis in the vertical direction 3 and connected to each other to support the skirt 100 in the vertical direction 3. [ That is, the height adjusting portion 300 and the supporting portion 200 are not structured to support the skirt 100 separately. Since the height adjusting portion 300 and the supporting portion 200 are connected to each other in a vertically aligned state to support the skirt 100 together, The height of the skirt 100 can be adjusted quickly and the load or impact applied to the skirt 100 or the belt 11 can be reduced while the height of the skirt 100 can be freely adjusted. The operation of the height adjusting unit 300 and the support unit 200 can be operated well without colliding with each other.

That is, the height adjusting unit 300 installed on the upper side forcibly adjusts the height of the skirt 100 to a desired height, and the supporting unit 200 installed on the lower side relatively moves the belt 11 and the rail 30, The height of the skirt 100 is automatically adjusted in response to the height change of the skirt 100. In addition, the support part 200 can assist the smooth movement while mitigating the impact of the skirt 100 when the skirt 100 moves up and down using the built-in elastic member 260. The height adjustment part 300 and the support part 200 coupled to the upper and lower sides support the overall load of the skirt 100 and tightly attach the skirt 100 to the edge of the upper surface of the belt 11 to maintain airtightness.

The stopper 400 is spaced apart from the support portion 200 in the longitudinal direction 2 so as to slidably support the skirt 100 in a vertical direction. The stopper 400 is mounted by connecting the chute 20 and the skirt 100 on the belt conveyor 10, and at least one stopper 400 may be mounted. In the embodiment of the present invention, the stopper 400 is mounted to be spaced apart from each other in the longitudinal direction 2 with two support portions 200 interposed therebetween. Of course, the number and position of the stoppers 400 are not limited to these, and may vary.

The stopper 400 receives the movement of the skirt 100 in the up and down direction 3 by the support part 200 and the height adjusting part 300 while moving the skirt 100 in the width direction 1 So that abnormal movement such as shaking or twisting of the width direction 1 and the length direction 2 of the skirt 100 can be suppressed or prevented.

The stopper 400 includes a stopper shaft 410 mounted on the skirt 100 in the vertical direction through the bracket 110, a slit 413 extending in the vertical direction through the stopper shaft 410 in the width direction, A slide bar 420 which is supported on the side of the lower cylinder 22 of the chute 20 of the belt conveyor 10 and whose other end penetrates the slit 413 in the width direction, And a stopper block 430 mounted thereon.

The stopper shaft 410 may include a bar shaped upper prime 412 on which the slit 413 is formed and a bar shaped lower prime 411 extending downward from the lower side. The lower prime 411 may be mounted on the upper surface of the bracket 110 in the vertical direction 3. The width of the slit 413 in the longitudinal direction 2 can correspond to the width of the longitudinal direction 2 of the slide bar 420. The outer circumferential surface of the slide bar 420 is in close contact with the inner wall of the slit 413 The movement in the longitudinal direction 2 can be restricted.

The slide bar 420 includes a slide bar body 421 extending in the width direction 1 and a protrusion 422 protruding to surround a predetermined position between one end and the other end of the slide bar body 421. The protrusion 422 The stopper block 430 and the stopper block 430 may be in contact with or in close contact with the upper prime 412 of the stopper shaft 410 in the width direction so that the movement in the width direction 1 may be restricted.

The stopper block 430 may include a mounting hole 432 passing through the center of one surface of the block body 431 facing the block body 431 and the upper prime 412. The other end of the slide bar body 421 can be screwed into the mounting hole 432. [

The skirt device is installed under the chute 20 facing the belt conveyor 10, It is possible to suppress or prevent the occurrence of lightning or dust during operation of the chute 20.

At this time, the chute 20 moves along the rail 30 and its position can be changed from time to time. At this time, the skirt 100 elastically supported on the support portion 200 smoothly maintains contact with the belt 11, The height of the supporting part 200 can be freely adjusted by the adjusting part 300 so that the height of the skirt 100 can be adjusted at any time as desired. The gap between the skirt 110 and the belt 11 is removed so that airtightness between the chute 20 and the belt 11 can be maintained smoothly and a part of the weight of the skirt 100 The wear of the contact surface between the skirt 100 and the belt 11 due to the load of the skirt 100 can be remarkably reduced. At this time, since the stopper 400 limits the movement of the skirt 100 in the width direction 1 and the length direction 2, it is possible to prevent abnormal movement of the skirt 100 in advance.
