Description

本発明はベルトコンベアから搬送物が落下するのを防止するベルトコンベア用スカート装置に関し、特に、石炭を搬送する際の落炭防止や発塵防止に優れるものに関する。   The present invention relates to a belt conveyor skirt device for preventing a conveyed product from falling from a belt conveyor, and more particularly, to an apparatus that is excellent in preventing coal falling and dust generation when coal is conveyed.

図２は、原料地区における石炭の移動経路を説明する模式図で、石炭ａは、石炭ヤードからローダー９０により切り出され、定量切出装置（ＣＦＷ）１００まで搬送される。   FIG. 2 is a schematic diagram for explaining the movement route of coal in the raw material area. Coal a is cut out from the coal yard by a loader 90 and conveyed to a quantitative cutting device (CFW) 100.

定量切出装置（ＣＦＷ）１００で一定量とされた石炭が砕炭機２００に搬送され、その後、コークス炉３００に投入される。   A certain amount of coal is transferred to the coal pulverizer 200 by the fixed quantity cutting device (CFW) 100 and then charged into the coke oven 300.

石炭の石炭ヤードからコークス炉までの移動は全てベルトコンベアによるので、ベルトコンベアは原料設備のほぼ９０％を占め、装備数８５０本、総延長は８０ｋｍにも達し、ベルトコンベアからの石炭の落下（以下、落炭）や、発塵は環境防災に大きな影響を与える。   Since all the movement of coal from the coal yard to the coke oven is carried out by a belt conveyor, the belt conveyor occupies almost 90% of the raw material equipment, the number of equipment is 850, the total length reaches 80 km, and the coal falls from the belt conveyor ( Hereinafter, charcoal removal and dust generation have a great impact on environmental disaster prevention.

特許文献１は、ベルトコンベヤ装置に関し、スカートによる運搬物の飛散防止効果とベルト及びキャリバーの耐久性を確保するため、ベルト裏面側に軸線がベルトの長手方向に沿って配置される複数のキャリバーとベルト裏面との間隔を、スカートの下部となる領域では、ベルト中央部の領域よりも小さくしたものが記載されている。   Patent Document 1 relates to a belt conveyor device, and a plurality of calibers whose axes are arranged along the longitudinal direction of the belt on the back surface side of the belt in order to ensure the effect of preventing the scattering of conveyed objects by the skirt and the durability of the belt and caliber. In the region where the distance from the back surface of the belt is the lower part of the skirt, the belt is smaller than the region at the center of the belt.

特許文献２は、ベルトコンベア用スカート装置に関し、ベルトが搬送物の落下衝撃により振動しても、スカートがその振動に追従できるように、スカート支持部をベルトを支持するキャリアローラのフレームに取り付け、更に当該支持部にスカートを弾性体を介して上下動自在に装着したものが記載されている。   Patent Document 2 relates to a skirt device for a belt conveyor, and even if the belt vibrates due to a drop impact of a conveyed object, the skirt support portion is attached to a frame of a carrier roller that supports the belt so that the skirt can follow the vibration. Further, a skirt is mounted on the support portion through an elastic body so as to be movable up and down.

図３は定量切出装置（ＣＦＷ）１００における落炭や発塵を防止する方法の一例を説明する図で、配合槽１０１の下部のスカート部１０７とフィーダベルト１０３の隙間はスカート１０２で覆われ、フィーダベルト１０３とスケールベルト１０６のテール部には飛散防止シュート１０５が取り付けられている。   FIG. 3 is a view for explaining an example of a method for preventing the falling of coal and dust generation in the quantitative cutting device (CFW) 100. Further, an anti-scattering chute 105 is attached to tail portions of the feeder belt 103 and the scale belt 106.

図４は、図３に示した定量切出装置（ＣＦＷ）の、フィーダベルト１０３の進行方向と直角方向の断面構造を示す図で、石炭ａの落炭や発塵を防止するため、スカート１０２の下端部はフィーダベルト１０３の上面と接するように配置される。
特開２００１−３１０８１１号公報 特開平７−２７７４６３号公報 FIG. 4 is a view showing a cross-sectional structure of the quantitative cutting device (CFW) shown in FIG. 3 in a direction perpendicular to the moving direction of the feeder belt 103. In order to prevent coal a from falling or dusting, the skirt 102 is shown. The lower end of the belt is disposed so as to contact the upper surface of the feeder belt 103.
JP 2001-310811 A JP-A-7-277463

ところで、原料ヤードから定量切出装置（以下、ＣＦＷ）に移送される石炭は、配合槽の上方のベルトコンベアから配合槽内に落下するので、配合槽下部のスカート部とフィーダベルトの隙間をスカートで覆っても、落下の衝撃力により既にスカート部に堆積している石炭がスカートを押し拡げて落炭が発生する。   By the way, the coal transferred from the raw material yard to the quantitative cutting device (hereinafter referred to as CFW) falls from the belt conveyor above the blending tank into the blending tank, so the gap between the skirt at the bottom of the blending tank and the feeder belt is skirted. Even if it is covered with, the coal already deposited on the skirt portion due to the impact force of the fall pushes and expands the skirt to generate coal fall.

特許文献１，２記載のベルトコンベア用スカート装置においてスカートはいずれもゴム製で、上述した現象を防止することはできない。   In the skirt device for belt conveyors described in Patent Documents 1 and 2, the skirts are all made of rubber, and the above-described phenomenon cannot be prevented.

そこで、本発明は、フィーダベルトを傷めることなく、フィーダベルト上の原料漏洩の防止が可能な、剛性の高いスカートを備えたベルトコンベア用スカート装置を提供することを目的とする。   Therefore, an object of the present invention is to provide a belt conveyor skirt device including a highly rigid skirt that can prevent the leakage of raw materials on the feeder belt without damaging the feeder belt.

本発明によれば、ゴム製のスカートを用いた場合に対し、以下の効果が得られ、産業上、極めて有用である。
１．稼動開始時に調整した後は、調整が不要である。
２．ベルトとスカートが接触する部分の磨耗損傷が抑制される。
３．スカートとベルトの隙間からの原料漏洩が大幅に低減する。 According to the present invention, the following effects can be obtained compared to the case of using a rubber skirt, which is extremely useful industrially.
1. After adjustment at the start of operation, no adjustment is required.
2. Wear damage at the portion where the belt and the skirt contact is suppressed.
3. Material leakage from the gap between the skirt and belt is greatly reduced.

本発明は、スカートとして円筒パイプを用いることを特徴とする。以下、図面を用いて本発明を詳細に説明する。   The present invention is characterized in that a cylindrical pipe is used as the skirt. Hereinafter, the present invention will be described in detail with reference to the drawings.

図１は、本発明の一実施例に係るベルトコンベア用スカート装置の構成を説明する図で、ベルトコンベアの進行方向と直角方向の断面を示す。図において１はベルトコンベア用スカート装置、２はスカート支持部、３は円筒パイプ固定用部材、４は円筒パイプ、５は調整及び固定用ボルト、６は調整及び固定用ボルトの頭部、７、８，９はナット、１０はベルトコンベア、１１はベルトコンベア１０のキャリアロール、１２は集合槽、２１は固定用部材、２２は固定用コッターピース、２３はコッターピン、３１は円筒パイプ固定用部材３の補強材を示す。   FIG. 1 is a diagram for explaining the configuration of a belt conveyor skirt device according to an embodiment of the present invention, and shows a cross section perpendicular to the traveling direction of the belt conveyor. In the figure, 1 is a belt conveyor skirt device, 2 is a skirt support, 3 is a cylindrical pipe fixing member, 4 is a cylindrical pipe, 5 is an adjustment and fixing bolt, 6 is a head of the adjustment and fixing bolt, 7, 8, 9 are nuts, 10 is a belt conveyor, 11 is a carrier roll of the belt conveyor 10, 12 is a collecting tank, 21 is a fixing member, 22 is a fixing cotter piece, 23 is a cotter pin, 31 is a cylindrical pipe fixing member 3 The reinforcing material is shown.

ベルトコンベア用スカート装置１は、スカート支持部２とスカートとしての円筒パイプ４を有し、集合槽１２に取り付けられる。   The belt conveyor skirt device 1 includes a skirt support 2 and a cylindrical pipe 4 as a skirt, and is attached to a collecting tank 12.

スカート支持部２と円筒パイプ４は、円筒パイプ４に溶接などで接合された円筒パイプ固定用部材３と、スカート支持部２に固定された固定用部材２１を、固定用ボルト５で結合及びコッターピース２２にコッターピン２３を打ち込み固定する。   The skirt support 2 and the cylindrical pipe 4 are formed by connecting a cylindrical pipe fixing member 3 joined to the cylindrical pipe 4 by welding or the like and a fixing member 21 fixed to the skirt support 2 with a fixing bolt 5 and a cotter. The cotter pin 23 is driven into the piece 22 and fixed.

円筒パイプ固定用部材３と固定用ボルト５は、円筒パイプ固定用部材３に設けたボルト孔（図では省略）に固定用ボルト５を螺合させて、円筒パイプ固定用部材３をナット８，９で上下方向から締め付けて、固定する。尚、円筒パイプ固定用部材３はナット８，９で固定されるので、ボルト孔の替わりに、ボルト径より大きな径の孔を設けてもよい。   The cylindrical pipe fixing member 3 and the fixing bolt 5 are formed by screwing the fixing bolt 5 into a bolt hole (not shown) provided in the cylindrical pipe fixing member 3 so that the cylindrical pipe fixing member 3 is connected to the nut 8, Tighten from 9 up and down to fix. Since the cylindrical pipe fixing member 3 is fixed by the nuts 8 and 9, holes having a diameter larger than the bolt diameter may be provided instead of the bolt holes.

円筒パイプ固定用部材３と固定用ボルト５は固定用部材２１に設けたボルト孔（図では省略）に、固定用ボルト５を螺合させて、ナット７を螺着させてその位置に固定させる。   The cylindrical pipe fixing member 3 and the fixing bolt 5 are screwed into a bolt hole (not shown in the figure) provided in the fixing member 21, and the nut 7 is screwed to fix in place. .

上述したように、円筒パイプ固定用部材３は、スカート支持部２に固定された固定用部材２１にボルトナット接合で結合されるので、円筒パイプを、スカート支持部に対し、上下の取り付け位置調整可能に装着することが可能である。   As described above, the cylindrical pipe fixing member 3 is coupled to the fixing member 21 fixed to the skirt support portion 2 by bolt and nut bonding, so that the cylindrical pipe is attached to the skirt support portion in the vertical position adjustment. It can be installed as possible.

円筒パイプ４には、上方から落下する石炭ａにより、外側に押し広げようとする力が働くので、円筒パイプ４の肩部と円筒パイプ固定用部材３の間に補強材３１を外側より取り付ける。   Since the force which tries to spread outward by the coal a which falls from upper direction acts on the cylindrical pipe 4, the reinforcing material 31 is attached from the outer side between the shoulder part of the cylindrical pipe 4 and the cylindrical pipe fixing member 3.

本発明では、円筒パイプ４の外径Ｄを、ベルトコンベア用スカート装置１内で、石炭ａが矢印ｃの方向に移動した際、空隙ｂが生じるように選定することが重要で、空隙ｂが生じることにより、一時的に円筒パイプとベルトコンベアが離れても落炭を防止することが可能となる。   In the present invention, it is important to select the outer diameter D of the cylindrical pipe 4 so that the gap b is generated when the coal a moves in the direction of the arrow c in the skirt device 1 for the belt conveyor. As a result, it is possible to prevent charcoal falling even if the cylindrical pipe and the belt conveyor are temporarily separated.

例えば、ＣＦＷに本発明に係るベルトコンベア用スカート装置を用いる場合、石炭ａの漏洩防止効果は外径Ｄ＝７０ｍｍが最も好ましい。また、鋼製の円筒パイプがベルトコンベアを傷つけることなく、耐摩耗性に優れ好ましい。   For example, when the belt conveyor skirt device according to the present invention is used for CFW, the outer diameter D = 70 mm is most preferable as the leakage prevention effect of coal a. A steel cylindrical pipe is preferable because it does not damage the belt conveyor and is excellent in wear resistance.
