Accordingly, the belt conveyor, which is a conveying means, is a device for conveying raw materials, fuel, and materials used in a steel mill, a power plant and a construction site to a designated position, and is installed to have a certain length on the outside.

At this time, rainwater or foreign matter easily flows on the conveyor which is open at the upper part in the process of transferring the processed material such as raw material and fuel to the supplied facility, which may cause a problem of deteriorating the quality of the processed material. In addition, a large amount of dust is generated due to a change in the vapor phase, such as a strong wind, in the process of transporting the processed material, and dust is scattered into the atmosphere. In this case, dust may be introduced into the atmosphere by dust, The work environment of the workplace is hindered and consequently there is a problem that it adversely affects the health of the worker and the facilities in the workplace.

However, when the dust cover is fixedly installed to cover the entire conveyor apparatus, the movement of the forward or backward tripper and the backward movement of the conveyor apparatus are prevented. The dust cover is not provided in a certain section in which the tripper moves. For this reason, there is a problem that the dust of the coke is scattered through a certain section in which the dustproof cover is not installed.

At this time, the dust cover 30 may be installed on the processing means 20 to prevent the dust of the object C from scattering. However, when the dust cover 30 is fixedly installed so as to cover the entire processing means 20, a section where the dust cover 30 interferes with the front and rear trippers 10 is generated. For this reason, conventionally, the dust cover is not provided in a predetermined section where the tripper 10 is moved back and forth, for example, about 80 m in order to prevent interference.

As described above, the anti-vibration device 500 shown in Fig. 2 can be installed to prevent the dust of the object C from scattering in the section where the anti-vibration cover 30 of Fig. 1 is not installed.

The anti-vibration device 500 will be described in detail with reference to FIGS. 3 to 7 described later.

At this time, the dust cover 400 is installed such that the length L and the height H can be varied and the length L of the dust cover 400 can be expanded and contracted in the direction in which the processed object C is conveyed . The height H of the dust cover 400 may be increased when the length L of the dust cover 400 is reduced. A detailed description thereof will be described later with assistance. The dust cover 400 includes a frame 200 mounted on the rail 100 and a dustproof sheet 300 supported by the frame 200.

The dustproof sheet 300 may be formed in a fabric shape with a cover sheet of a kind. The dustproof sheet 300 covers the upper portion of the processing means 20 and the processed object C so as to block the dust generated during the transfer of the processed object C through the processing means 20 from being scattered in the atmosphere, (200). In addition, it may be arranged long under the rail 100 so that the dust is not scattered to the lower portion of the processing means 20. [ The dustproof sheet 300 may be manufactured such that at least a part of the area of the dustproof sheet 300 is made of a light transmitting material so that the state of the processed material C to be processed through the processing means 20 can easily be confirmed from the outside And the entire area may be made transparent as shown in FIG.

The light-transmitting material for forming the dustproof sheet 300 may be formed of at least one of synthetic resin, vinyl chloride resin, polystyrene, ABS (acrylonitrile, butadiene and styrene) resin and acrylic resin.

In addition, since the dust cover 400 can be moved and the length thereof can be varied, the dust cover 300 can also be changed while being folded or spread according to the length variation of the dust cover 400. At this time, the dust-proof sheet 300 may be made of a material such as cloth or vinyl that can be spread or folded according to the expansion and contraction of the dust cover 400. The method of joining the dustproof sheet 300 will be described later with reference to Figs. 10 to 12 shown later.

The frame 200 is a means for supporting the anti-vibration sheet 300 and sliding on the rail 100. The frame 200 includes a plurality of support frames 210 movably installed in forward and backward directions, a link 230 connecting the support frames 210, a lift frame 250 installed to be movable up and down on the support frame 210, And an auxiliary link 270 connecting the lifting frame 250 and the supporting frame 210 to each other to move the lifting frame 250 up and down. Here, in the present invention, although the direction of movement of the frame 200 is shown as being movable forward and backward, the direction of movement of the frame 200 is not limited thereto and may be applied to all directions in which the rail 100 is installed. A detailed description of the structure of the frame 200 will be given later with reference to Figs. 4 to 7.

The support frame 210 includes a horizontal portion 210a extending in the left and right direction and a pair of vertical portions 210b extending downward in a direction orthogonal to both ends of the horizontal portion 210a. The wheels 210c and 210d coupled to the rail 100 are disposed on the rail 100 at the lower end of the vertical part 210b. At this time, a support 210e to which the wheels 210c and 210d are coupled may be provided at a lower end of the vertical part 210b.

The wheels 210c and 210d may be constituted by an upper wheel 210c disposed on the upper surface of the upper rail 120 and a lower wheel 210d disposed in close contact with the upper surface of the inner surface of the lower rail 110. [ A portion of the rail 100 is simultaneously supported between the upper wheel 210c and the lower wheel 210d so that the support frame 210 can be fixed to the rail 100 so as to cover the upper portion of the processing means 20. [ have. When the wheels 210c and 210d are fixedly coupled to the support 210e, it is possible to prevent the wheels 210c and 210d from deviating due to vibration and external shocks applied to the wheels 210c and 210d.

The upper wheel 210c may be a V-shaped wheel to be disposed on the upper rail 120 configured in a triangular shape. However, the shape of the upper wheel 210c is not limited to this, and di- and U-shaped wheels may be used.

The links 230 may be constructed of a pair of link members whose middle portions are hinged to each other and both ends of the link members are slidable in a sliding groove 215 formed in the vertical portion 210b of the support frame 210 Lt; / RTI > 7 (b), when the support frame 210 is mutually spaced apart (l ₁ ) or close (l ₂ ), the link 230 is separated from the support frame 210 by a certain angle θ ₁ ) Or close (? ₂ ), so that the support frames 210 connected to the link 230 can be supported while being held parallel to each other.

The lifting frame 250 includes a horizontal portion 250a extended to the left and right and a pair of vertical portions 250b extending downward in a direction orthogonal to both ends of the horizontal portion 250a. The vertical portion 250b of the lifting frame 250 can be vertically coupled to the vertical portion 210b of the support frame 210. The elevation frame 250 may include a vertical portion 250b and a guide pipe 210f extending in a direction parallel to the vertical portion 210b. And the lower end of the guide pipe 210f can be coupled with the guide pipe 210f. A detailed description thereof will be described with reference to FIGS. 8 and 9. FIG.

The auxiliary link 270 may have rings at both ends and may include a horizontal portion 250a of the lifting frame 250 and a supporting frame 210 disposed forwardly or rearwardly of the supporting frame 210 on which the lifting frame 250 is installed 210 to the horizontal portion 210a. 7, A of the auxiliary link 270 is coupled to the horizontal portion 250a of the lifting frame 250, and A 'is a horizontal portion 210a of the support frame 210 spaced apart from the horizontal portion 250a, Lt; / RTI > Accordingly, when the gap between the support frames 210 is close to or spaced from the support frame 210, the auxiliary link 270 can be rotated in the vertical direction to elevate the lift frame 250. At this time, the lifting frame 250 is lifted when the supporting frames 210 are brought close to each other, and is lowered when the supporting frames 210 are spaced apart from each other.

FIG. 8 is a view showing that the dust cover 400 is extended to separate the frames 200, and FIG. 9 is a view showing that the dust cover 400 is reduced in length and the frames 200 are brought close to each other.

Before describing the length and height variation of the dust cover 400, it is explained that one end of the dust cover 500 is fixed and the other end is pushed or pulled to stretch the dust cover 400. However, since both ends of the dustproof device 500 can be pushed or pulled to extend and contract the length of the dustproof cover 400, the method of fixing and moving the dustproof device 500 is not limited.

8A, when the length of the dust cover 400 is increased to L ₁ , the upper and lower angles of the link 230 disposed between the support frames 210 are maximized, Thereby increasing the spacing. At this time, as described above, the lift frame 250 is lowered by the rotation of the auxiliary link 270, and is positioned at a height substantially equal to the height of the support frame 210. 8 (c), the vertical portion 250b of the lifting frame 250 may be disposed in a state of being fitted to the vertical portion 210b of the support frame 210. As shown in FIG.

9, when the length of the dust cover 400 is set to L ₂ , the distance between the support frames 210 spaced apart from each other is narrowed. At this time, the upper and lower angles of the link 230 disposed between the support frames 210 are minimized, and the support frames 210 are brought close to each other. At this time, the lift frame 250 is raised from the height H _{1 to} the height H ₂ by the rotation of the auxiliary link 270, as described above. At this time, as shown in FIG. 9 (c), obtained by subtracting the height as in the H ₁ from the H ₂ from the fitting arrangement to the vertical portion (210b) of the vertical portion (250b) has a support frame 210 of lift frame 250, h < / RTI >

The frame 200 is easily exposed to the external environment, the link 230 and the auxiliary link 270 are rotated, and the frame 200 is moved. Therefore, the frame 200 may be formed of at least one of a stainless steel (STS) series and a metal having corrosion resistance so that the frame 200 can be replaced at an increased time.

The dustproof device 500 formed as described above is constructed in the form of a tunnel and is provided so as to cover the upper part of the object C and is provided with a dustproof sheet 300 on the periphery of a plurality of frames 200 which are close or spaced apart It is possible to prevent the tripper 10 from interfering with the dustproof device 500 by expanding and contracting the overall length of the dustproof device 500 in accordance with the forward and backward movement of the tripecar 10.

At this time, the anti-vibration device 500 may be fixed to the tripper 10 and the rail 100, including a separate connecting means (not shown) and fixing means (not shown). The support frame 210 closest to the tripper 10 is connected to one end of the vibration damping device 500 and the fixing means is disposed at the other end of the vibration damping device 500, It is possible to fix the end portion of the anti-vibration device 500 to the rail 100. As the connection means, a fitting hole is formed at one end of the dustproof device 500 to which the dustproof device 500 and the tripecar 10 are connected, a pin is formed in the tripecar 10, It is possible. It is preferable that the connecting means is not limited and the one end of the tripricer 10 and the vibration isolating device 500 are stably connected to each other and connected to the vibration and impact generated by the movement of the tripecar 10 Do. As a method of fixing the vibration isolator 500, a rail stopper may be installed in the moving direction of the support frame 210 so that the support frame 210 farthest away from the tripper 10 can be fixed And the wheels 210c and 210d connected to the support frame 210 are fixed and fixed so as not to be moved. At this time, not only the rail stopper but also the wheels 210c and 210d of the support frame 210 may be removed, and the vibration damper 500 may be fixed using welding and bolting.

10, an observation window 320 can be provided in a part of the dustproof sheet 300 to allow confirmation of the inside of the dustproof device 500, as shown in FIG. At this time, the observation window 320 may be constructed by fixing vinyls and sheets having transparent properties to the openings 320a formed in the upper and lower middle regions of the dustproof sheet 300.

In addition, the dustproof sheet 300 may be divided into a plurality of parts, and the parts may be mutually connected by the attachment member 340 provided at the adjacent end in a state where the parts overlap each other at a predetermined interval. At this time, the attachment member 340 may be formed of at least one of a velcro, a button, and a zipper type. The attachment member 340 is not limited to the above-described material, but it is preferable that the attachment member 340 is formed of a material capable of replacing the vibration-damping sheet 300 during maintenance of the vibration-damping device 500.

For example, when the Velcro is used between the vibration-damping sheets 300 with the attachment member 340, the Velcro (not shown) disposed at a certain overlapping position of the vibration-damping covers 300 is detachable, When the sheets 300 are overlapped and disposed, the velcro seals the space between the dustproof sheets 300 to prevent scattering of dust. In addition, since a plurality of the dustproof sheets 300 are provided, only the dustproof sheets 300 requiring maintenance during maintenance of the dustproof apparatus 500 can be selectively separated and maintained, There is an advantage of easy maintenance.

The dustproof sheet 300 may be fixed to the lifting frame 250 so that the dustproof sheet 300 can be lifted upward when the support frames 210 are brought close to each other as shown in FIG. This is because when the support frames 210 are brought close to each other, a resistance is generated in the air flow inside the vibration insulating device 500 by the folded dustproof sheet 300, A large amount of dust can be prevented from being generated. At this time, the fixing member 310 may be used to fix the dustproof sheet 300 to the lifting frame 250.

The fixing member 310 may be fixed using at least one of a tape, a bond, a clamp, and a Velcro. Further, the fixing member 310 is not limited to the member to be arranged.

That is, when processing the processed object C by using the processing means 20, the flow of air in the conveying direction may occur in accordance with the conveyance of the processing means 20. In addition, since the width of the dustproof device 500 is varied, a lot of dust may be generated inside the dustproof device. At this time, when the dust-proof sheet 300 for preventing scattering of dust is installed directly on the support frame 210, when the support frames 210 are close to each other and the width of the vibration- The intermediate portion of the anti-vibration sheet 300 may protrude toward the inside of the frame 200. As described above, the dustproof sheet 300 protruding into the interior of the frame 200 generates a resistance to the flow of air flowing from the front to the rear in the processing direction, causing the air to vortify, (C), a large amount of dust can be generated.

According to the present invention, by installing the dustproof sheet 300 on the lifting frame 250, when the width of the dustproof device 500 is narrowed, the lifting frame 250 lifts the dustproof sheet 300, The air flow can be minimized by the portion. Thus, it is possible to prevent the dust inside the dustproof device 500 from being scattered to the outside. That is, the high density of the dust that can be generated by narrowing the width of the dustproof device 500 can be solved by increasing the height of the dust cover 400.

In the modification of Fig. 11, the dustproof sheet 300 may be fixed to the auxiliary link 270 as shown in Fig.

The dustproof sheet 300 may be provided with a fixing clamp 330 which is coupled to the auxiliary link 270 on the inner surface of the upper portion so that the upper surface of the dustproof sheet 300 may be fixed to the auxiliary link 270. When the length of the anti-vibration device 500 is changed, the upper surface of the anti-vibration sheet 300 is fixed to the auxiliary link 270 so that when the anti-vibration sheet 300 is rotated by the auxiliary link 270, The respective portions of the dustproof sheet 300 can be folded in a uniform shape. Therefore, there is an advantage that the middle portion of the dustproof sheet 300 can be prevented from being unevenly folded and caught between the auxiliary links 270.

Referring to FIG. 13, the dustproof device 500 may be provided with a sedimentation sheet 290.

The settling sheet 290 is disposed inside the vibration damping device 500, and is formed into a plate shape having a predetermined area, and a plurality of through holes 293 passing through the plate may be formed. In order to mount the sedimentation sheet 290 to the frame 200, a fixing band 295 capable of fixing the sedimentation sheet 290 and the frame 200 may be provided.

The settling sheet 290 flows backward through the through holes 293 of the settling sheet 290 by the flow of the processing means 20 from the front to the rear of the processing means 20. Therefore, the dust contained in the air flowing rearward can be caught by the settling sheet 290 so that it can not flow backward, so that the dust is deposited, thereby preventing the dust from being discharged to the rear end of the dust- There is an advantage that dust can be prevented from adhering to the dustproof sheet 300 and the frame 200 and growing. In addition, since the dust-proof device 500 is movable, when the dust-proof device 500 is extended on the side of the supplying device B of the processing device 20 and the length thereof increases, The sheet 290 pushes the dust contained in the air from the supply facility A to the supply destination facility B and moves. Therefore, the dust moves to the dust collector 15 provided in the tripper 10, and dust can be easily removed without scattering. The sedimentation sheet 290 may be formed of a cloth or vinyl material such as the dustproof sheet 300. At this time, it is preferable that the lower end of the settling sheet 290 is disposed so as to be spaced upward from the processing means 20 so as not to interfere with the processing object C to be processed by the processing means 20. Although the shape of the through hole 293 is circular in the drawing, the shape of the through hole 293 is not limited to this, and may be formed in various shapes such as an elliptical shape and a polygonal shape.

14, when a plurality of sedimentation sheets 290 are continuously arranged in the dustproof device 500, the more the sedimentation sheet 290 is disposed in the direction of conveyance of the treated material C, that is, The through-hole diameter R of the through-hole 293 may be gradually reduced as R1, R2, and R3, as it goes from the facility A to the feeder B side. In this case, due to the characteristics of the dustproof device 500, the through hole 293 of the sedimentation sheet 290 at the supply facility A where the pressure is maximized can be formed to be large, so that the influence of the pressure can be minimized. Further, while the dust is passed through the settling sheet 290 formed with the progressively reduced through holes 293, the kinetic energy of the dust is reduced, so that the dust of the large particles, which is highly influenced by gravity, is deposited first, Fine dust can also be deposited in the vicinity of the water supply facility B side of the water C, and the effect of the gravity dust collection facility can be obtained.

As described above, according to the embodiment of the present invention, by including the dust-proof sheet 300 covering the upper portion of the processing means 20 and the processed object C and having a variable length and height, And can be connected to the tripper 10. As a result, it is possible to solve the interference part due to the movement of the tripper 10, to prevent scattering of the dust generated in the treated material C, and to prevent environmental pollution in the atmosphere and the workplace. The sedimentation sheet 290 is continuously installed in the dustproof device 500 so that the sedimentation sheet 290 pushes the dust and the dust easily flows into the dust collector 15 and the sedimentation sheet 290 flows into the dust flow It is possible to prevent the dust from being scattered to the rear of the dustproof device 500.

By fabricating at least a part of the dust-proof sheet 300 from a light-transmitting material, it is possible to easily confirm the processing means 20 and the processing object C from the outside, have.

In addition, since the plurality of frames 200 formed as described above are continuously installed in the dustproof device 500, the partial frame 200 can be replaced during the maintenance of the dustproof device 500, And reduce maintenance costs and time.

Although the present invention has been described with reference to the accompanying drawings and the preferred embodiments described above, the present invention is not limited thereto but is limited by the following claims.
