本発明は、連続搬送式コンベヤ上の石炭あるいはコーク
スに対する赤外線式水分測定器を設けた石炭・コークス
用搬送設備に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a coal/coke conveying facility equipped with an infrared moisture measuring device for coal or coke on a continuous conveyor.
赤外線式水分測定器は、その受光部と測定対象の石炭や
コークスとの距離が変動すると測定精度が悪くなるため
、従来、測定箇所よりも搬送上手側に、コンベヤ上の石
炭あるいはコークスの堆積厚さを一定化する均し具を設
けていた。The measurement accuracy of infrared moisture measuring instruments deteriorates when the distance between the light receiving part and the coal or coke to be measured changes. A leveling tool was installed to keep the surface level constant.
しかし、−ａにコンベヤ上の石炭やコークスの本来の堆
積厚さはかなり大きくかつ不規則に変動するため、実際
上、搬送面でのトラブルを生じること無く、精度良好な
水分測定を行うことは極めて困難であった。However, since the original deposited thickness of coal and coke on the conveyor fluctuates considerably and irregularly, it is practically impossible to measure the moisture content with good accuracy without causing trouble on the conveyor surface. It was extremely difficult.
つまり、均し具をそれによる堆積厚さ一定化が確実に行
えるようにコンベヤに近付けぎみにセットすると、本来
の堆積厚さが均し具とコンベヤの間隔よりも大になる時

傷やベルトの蛇行等のコンベヤのトラブルが生じる共に
、こぼれ落ちた石炭やコークスの除去に多大の労力を要
する等の問題を生じる。In other words, if the leveling tool is set too close to the conveyor to ensure a constant deposition thickness, it will take longer for the original thickness of the pile to become larger than the distance between the leveling tool and the conveyor. A large amount of coal and coke pushed away by the leveling tool spills from the conveyor, causing problems with the conveyor such as damage to the carrier rollers and meandering of the belt, as well as the need for a great deal of effort to remove the spilled coal and coke. occurs.
したがって、実際には、均し具をコンベヤから離しぎみ
にセットして、石炭やコークスが余りこぼれ落ちないよ
うにする必要があり、そのために、本来の堆積厚さが均
し具とコンベヤの間隔よりも小になる時間が長くなり、
均し具が作用しなくなって、水分測定器の受光部と石炭
やコークスとの距離変動が大きくなり、水分測定精度が
悪くなる。Therefore, in reality, it is necessary to set the leveling tool far enough away from the conveyor to prevent too much coal or coke from spilling out, and to do this, the original thickness of the pile should be smaller than the distance between the leveling tool and the conveyor. It takes a longer time to become small,
The leveling tool stops working, and the distance between the light-receiving part of the moisture meter and the coal or coke increases, resulting in poor moisture measurement accuracy.
本発明の目的は、搬送上のトラブルを全く生じること無
く、精度良好な水分測定を確実に行えるように、しかも
設備面でも有利にする点にある。An object of the present invention is to ensure that moisture measurement with good accuracy can be performed without causing any transportation troubles, and to provide advantages in terms of equipment.
本発明の特徴構成は、コンベヤ上の石炭あるいはコーク

の通りである。The characteristic configuration of the present invention is that a light receiving part of an infrared moisture measuring device for coal or coke on a conveyor is attached so that the level can be adjusted freely by a drive device, and a device for measuring the distance between the coal or coke on the conveyor and the light receiving part is provided. A contact sensor is provided, a means for determining whether a distance measured by the sensor is within a set range, and an instruction from the determining means to maintain the value measured by the sensor within the set range. In addition, an output means for automatically operating the drive device is provided, and its effects are as follows.
つまり、非接触式のセンサーによって、コンベヤ上の石

光部と石炭やコークスとの距離が石炭やコークスの堆積
厚さの大巾な変動にかかわらず余り変化しないように、
受光部を自動的に駆動昇降させるのである。In other words, a non-contact sensor measures the distance between the light-receiving part of the infrared moisture meter and the coal or coke on the conveyor without applying any external force to the coal or coke on the conveyor, and outputs a determination means and output. By the action of the means, the distance between the light receiving part and the coal or coke does not change much even if the deposited thickness of the coal or coke varies widely.
The light receiving section is automatically driven up and down.
したがって、コンベヤ上の石炭やコークスが落とされる
ことが全く無く、良好な搬送を確実に維持でき、かつ、
赤外線式水分測定器による連続的な水分測定を、受光部

と無く、確実に精度良く行える。Therefore, coal and coke on the conveyor never fall off, ensuring good conveyance, and
To reliably and accurately perform continuous moisture measurement using an infrared moisture meter without being adversely affected by distance fluctuations between a light receiving part and coal or coke.
また、コンベヤの昇降に比して駆動負荷がはるかに小さ
い受光部を昇降させることによって、設備を小型かつ安
価にできる。Furthermore, by raising and lowering the light receiving section, which requires a much smaller driving load than raising and lowering a conveyor, the equipment can be made smaller and cheaper.
その結果、石炭やコークスを搬送しながら連続的に水分
