穀物油処理ダストエリア21防爆リチウム電気フォークリフトの作業紹介(図1)

穀物油処理ダストエリア21のリスク特性

穀物や油の加工工程では、でんぷんや油脂の粉塵が大量に発生し、可燃性があります。濃度が爆発限界に達すると、火花や高温などの火元が爆発しやすくなります。エリア21は、通常の運転中に爆発性粉塵環境が発生する可能性のある粉塵爆発危険エリアに属します。作業シーンでは粉塵濃度が頻繁に変動するため、作業設備の防爆性能に厳しい要件が課せられます。通常のフォークリフトは、電気火花や機械的摩擦火花などのリスクがあるため、このエリアで安全に運転できません。防爆基準を満たす特殊なフォークリフトを選択する必要があります。

ゾーン21での防爆リチウムフォークリフトの適合性

防爆リチウム電気フォークリフトは粉塵爆発環境に対して特殊な設計を行い、電気システムから機械部品まで防爆措置をとった。電気部分は防爆型構造を採用し、回路火花の流出を避ける機械部品は静電気防止処理を増やし、摩擦火花の発生を減らすリチウム電池自体は安定した化学性能を持っており、電池故障によるリスクを低減している。従来の燃料防爆フォークリフトと比べて、リチウム電気フォークリフトは騒音が低く、ゼロエミッションで、密閉または半密閉の穀物油加工現場環境に適していると同時に、エネルギー利用率が高く、長時間の作業ニーズを満たすことができる。

エリア21防爆リチウム電気フォークリフトの操作仕様

作業前のチェックポイント

オペレーターは、事前にフォークリフトを包括的に検査し、防爆シェルにひびが入っていないか、ガスケットが良好であるかなど、防爆部品の完全性を確認し、電気システムに露出した配線がないことを確認する必要があります。同時に、リチウム電池の電力と状態を確認し、漏れや膨らみなどの異常がないことを確認します。また、作業エリアのダスト濃度を検出して、フォークリフトが安全な範囲内で再起動するようにします。

ジョブプロセスの操作要件

作業中は、急加速や急ブレーキによる摩擦火花を避けるために、走行速度を厳密に制御する必要があります。材料を運ぶときは、材料のこぼれを防ぎ、ほこりの濃度を上げると同時に、フォークリフトがワークショップの設備や壁と衝突しないようにし、機械部品が損傷して火花が発生しないようにします。オペレーターは、静電気による危険を避けるために、静電気防止のオーバーオールと靴を着用する必要があります。

作業後のメンテナンス事項

作業が終わった後、フォークリフトに付着した粉塵、特に電気部品とリチウム電池の表面をすぐに掃除して、粉塵の堆積による危険を防ぐ必要がある。防爆部品を定期的に専門的に検査して、防爆性能が基準を満たしていることを確認する。リチウム電池は専用の静電気防止区域に保管して、高温多湿な環境を避けて、電池の寿命を延ばすと同時に安全を保障しなければならない。
