Description

本発明は、自掃式落鉱防止ベルト構造に関し、特に、リターン側ベルトから落下・堆積した微粉鉱の重量の増加により落鉱防止ベルトを降下させ、タッチローラを回転させて落鉱防止ベルトを回転させ、微粉鉱を落下除去するための新規な改良に関する。   The present invention relates to a self-cleaning orefall prevention belt structure, and in particular, the fallen prevention belt is lowered by increasing the weight of fine ore that has fallen and accumulated from the return side belt, and the touch roller is rotated to remove the orefall prevention belt. It relates to a new improvement for rotating and removing fine ores by dropping.

従来、用いられていたこの種のベルトコンベアにおいては、原料を搬送するベルトコンベアに付着した微粉鉱等を除去する構成としては、例えば、特許文献1のコンベアベルトの付着物除去装置及び特許文献2のベルトコンベア用クリーナを挙げることができる。   Conventionally, in this type of belt conveyor that has been used, as a configuration for removing fine ore and the like adhering to a belt conveyor that conveys raw materials, for example, a deposit removal device for a conveyor belt in Patent Document 1 and Patent Document 2 are used. There may be mentioned a belt conveyor cleaner.

前述の各構成を用いて原料を搬送するコンベアの表面に付着した微粉鉱をリターン側で除去した場合、ベルトコンベアから落下した微粉鉱は受け手段である防止板上に堆積されるため、人力によって突捧又はスコップ等、又は、バイブレータ等の振動を与えて下方へ落下処理していた。   When the fine ore adhering to the surface of the conveyor that conveys the raw material is removed on the return side using each of the above-described configurations, the fine ore that has fallen from the belt conveyor is deposited on the prevention plate that is a receiving means. It was dropped down by giving vibrations such as a tribute or scoop or a vibrator.

従来のベルトコンベアは、以上のように構成されていたため、次のような課題が存在していた。
すなわち、防止板上へ堆積した微粉鉱は、人力によって突捧又はスコップ等又は、バイブレータ等で除去していたため、種々課題が存在していた。
まず、突捧又はスコップによる除去は、対象が重量のある微粉鉱であるため、この除去作業は重筋作業であり、場所が狭い所、高い所等のように安全上問題となる場合が多く、容易な作業ではなかった。
また、バイブレータを用いる構成は、人的には容易な作業であるが、バイブレータの電源を配線工事するためには、費用が高額となり、かつ、バイブレータが取付不可能な落鉱防止板やシュートが多く、除去作業の機械化及び電動化が困難であった。
Since the conventional belt conveyor was comprised as mentioned above, the following subjects existed.
That is, the fine ore deposited on the preventive plate has been removed by human power with a bump or scoop or a vibrator, and thus various problems existed.
First of all, the removal by scooping or scooping is a heavy fine mine, so this removal work is a heavy work, and there are many safety problems such as narrow places and high places. It was not an easy task.
In addition, the configuration using a vibrator is an easy task for humans, but it is expensive to install a vibrator power supply, and there is no falling or prevention plate or chute that cannot be attached to the vibrator. In many cases, mechanization and motorization of the removal work were difficult.

本発明による自掃式落鉱防止ベルト構造は、ベルトコンベアで原料を搬送する際に、前記ベルトコンベアのリターン側ベルトから落下する微粉鉱を受けるため傾斜して配設された落鉱防止ベルトと、前記落鉱防止ベルトを回転自在に支持するベルト枠を架台から回動自在に吊り下げるための引張りばね部材と、前記ベルト枠の上部に回転自在に設けられ前記リターン側ベルトの上方に位置するタッチローラと、前記タッチローラと前記落鉱防止ベルトを連動させるための連動ベルトと、前記ベルト枠の下部に設けられ、曲折したコンベア支持枠により前記ベルト枠を回動自在に軸支するための軸支部とからなり、前記落鉱防止ベルト上に前記微粉鉱が堆積して前記ベルト枠が下降して前記タッチローラが前記リターン側ベルトと接触し、前記タッチローラの回転によって前記落鉱防止ベルトが回転することにより、前記微粉鉱が下方へ滑落して移送されるようにした構成である。 Self掃式落鉱prevent belt structure according to the present invention, when conveying a material in the belt conveyor, drop ore prevention belt disposed in order sloping receive fines ore falling from the return side the belt of the belt conveyor A tension spring member for rotatably suspending a belt frame that rotatably supports the falling-off prevention belt from a gantry, and a rotary spring provided on an upper portion of the belt frame and positioned above the return side belt. A touch roller, an interlocking belt for interlocking the touch roller and the falling-off prevention belt, and a belt support member provided at a lower portion of the belt frame and rotatably supported by the bent conveyor support frame. shaft support Toka Rannahli of said fine ore is deposited descends the belt frame in the落鉱prevent belt contacts the touch roller and the return side belt, the By the落鉱prevention belt is rotated by the rotation of Tchirora, the pulverized ore is a structure in which so as to be fed moves to slide down downward.

本発明による自掃式落鉱防止ベルト構造は、以上のように構成されているため、次のような効果を得ることができる。
すなわち、落鉱防止ベルトの上に堆積した微粉鉱を除去するためのベルトの駆動力を、ベルトコンベアに当接させて回転するタッチローラによって得るため、バイブレータ等の電源やエア源を必要とせず、簡単な構成で自動除去を行うことができる。
また、落鉱堆積を完全に防止し、人力による除去作業がなくなり、落鉱による種々のトラブル、ベルトコンベア設備の損傷等を防止することができる。
Since the self-cleaning falling-off prevention belt structure according to the present invention is configured as described above, the following effects can be obtained.
That is, since the driving force of the belt for removing fine ore deposited on the falling-off prevention belt is obtained by a touch roller that rotates in contact with the belt conveyor, a power source such as a vibrator or an air source is not required. Automatic removal can be performed with a simple configuration.
Further, it is possible to completely prevent falling ore deposits, eliminate the removal work by human power, and prevent various troubles caused by falling or damage to the belt conveyor equipment.

本発明は、ベルトコンベアから落下する微粉鉱が堆積する落鉱防止ベルトを、ベルトコンベアと連動するタッチローラの回転によって駆動させ、電動手段等を付加することなく簡単かつ確実に微粉鉱を除去するようにした自掃式落鉱防止ベルト構造を提供することを目的とする。   The present invention drives a falling-off prevention belt on which fine ore falling from a belt conveyor is deposited by rotation of a touch roller interlocked with the belt conveyor to easily and reliably remove fine ore without adding electric means or the like. It is an object of the present invention to provide a self-cleaning falling-off prevention belt structure.

以下、図面と共に本発明による自掃式落鉱防止ベルト構造の好適な実施の形態について説明する。
図1において符号1で示されるものは鉱石、コークス及び石炭等の原料2を目的とする炉等の場所に搬送するためのベルトコンベアであり、このベルトコンベア1のリターン側ベルト3の下方位置には、搬送ベルト4上に微粉鉱5を供給するための落鉱防止ベルト6が傾斜した状態で配設されている。尚、この搬送ベルト4で微粉鉱を受ける以外の手段として、バケットで受けたり、ピットに落し込むように構成することができる。
A preferred embodiment of a self-cleaning falling-off prevention belt structure according to the present invention will be described below with reference to the drawings.
1 is a belt conveyor for transporting raw materials 2 such as ore, coke, and coal to a place such as a furnace for the purpose, in a position below the return side belt 3 of the belt conveyor 1. Is arranged in a state in which the falling-off prevention belt 6 for supplying the fine ore 5 on the conveyor belt 4 is inclined. In addition, as means other than receiving the fine ore by the transport belt 4, it can be configured to receive by a bucket or drop into a pit.

前記落鉱防止ベルト6は、設備の固定側である架台7側に一端8aを固定された一対の引張りばね部材8の他端8bが接続されたベルト枠9を有しており、このベルト枠9の下部9aは曲折したコンベア支持枠10の軸支部9Aを介して矢印Aの方向に回動自在に設けられている。尚、引張りばね部材8は、スプリング、ゴム等からなる。 The falling-off prevention belt 6 has a belt frame 9 in which the other end 8b of a pair of tension spring members 8 having one end 8a fixed thereto is connected to the gantry 7 side which is a fixed side of the equipment. bottom 9a of 9 is rotatably provided in the direction of the arrow a via the shaft support 9A of the conveyors the supporting frame 10 which is bent. The tension spring member 8 is made of a spring, rubber or the like.

前記ベルト枠9の上部9bには、タッチローラ11が回転自在に軸支して設けられ、このタッチローラ11はリターン側ベルト3の上方に隙間Gを有して位置し、かつ、ベルトコンベア1内に位置している。前記落鉱防止ベルト6と前記タッチローラ11とは連動ベルト20によって連動して回転するように構成されている。   A touch roller 11 is rotatably supported on an upper portion 9b of the belt frame 9. The touch roller 11 is located above the return side belt 3 with a gap G, and the belt conveyor 1 Located in. The falling-off prevention belt 6 and the touch roller 11 are configured to rotate in conjunction with each other by an interlocking belt 20.

次に、動作について説明する。まず、ベルトコンベア1が作動して原料2が搬送され、この原料2の微粉鉱5がリターン側ベルト3に付着して案内ローラ30迄くると、この微粉鉱5は傾斜配置で回転停止状態の落鉱防止ベルト6上に落下して堆積する。   Next, the operation will be described. First, when the belt conveyor 1 is actuated and the raw material 2 is conveyed, and the fine ore 5 of the raw material 2 adheres to the return side belt 3 and reaches the guide roller 30, the fine ore 5 is in a rotation stop state in an inclined arrangement. It falls on the falling prevention belt 6 and accumulates.

通常、この落鉱防止ベルト6は一対の引張りばね部材8の引張力によって上方へ付勢されているため、タッチローラ11とリターン側ベルト3とは非接触状態が保持されているが、前述の堆積が進行して所定の重量に達すると、引張りばね部材8の引張り力に抗してベルト枠9が降下するため、タッチローラ11とリターン側ベルト3とが接触し、タッチローラ11が回転を始める。   Usually, since the falling-off prevention belt 6 is urged upward by the tensile force of the pair of tension spring members 8, the touch roller 11 and the return side belt 3 are kept in a non-contact state. When the deposition progresses and reaches a predetermined weight, the belt frame 9 descends against the tensile force of the tension spring member 8, so that the touch roller 11 and the return side belt 3 come into contact with each other, and the touch roller 11 rotates. start.

前記タッチローラ11の回転により、落鉱防止ベルト6とタッチローラ11とを連動させるための連動ベルト20によって落鉱防止ベルト6が回転し、この回転によって落鉱防止ベルト6上の微粉鉱5は下方へ滑落し、搬送ベルト4などにて所定の場所へ搬送される。   Due to the rotation of the touch roller 11, the collapsing prevention belt 6 is rotated by the interlock belt 20 for interlocking the falling-off prevention belt 6 and the touch roller 11, and the fine ore 5 on the falling-out prevention belt 6 is rotated by this rotation. It slides down and is transported to a predetermined place by the transport belt 4 or the like.

前述の微粉鉱5が落鉱防止ベルト6から落下すると、落鉱防止ベルト6の重量は軽くなり、再び、各引張りばね部材8の引張力によって上方へ上昇し、タッチローラ11とリターン側ベルト3とは非接触状態となって回転が止まり、落鉱防止ベルト6上への微粉鉱5の堆積が始まる。   When the fine ore 5 falls from the falling-off prevention belt 6, the weight of the falling-off prevention belt 6 becomes lighter and again rises upward by the tensile force of each tension spring member 8, and the touch roller 11 and the return side belt 3. , The rotation stops and the accumulation of fine ore 5 on the falling-off prevention belt 6 starts.

本発明は、製鉄所の設備だけではなく、食品関係等の設備にも適用可である。   The present invention is applicable not only to facilities in steelworks but also to facilities related to food.
