Description
本考案は、油、空気、水、塗料、溶剤などの流体送路に挿入され、流体から異物を分離するための濾過装置に関する。 The present invention relates to a filtering device that is inserted into a fluid passage such as oil, air, water, paint, and solvent and separates foreign substances from the fluid.
従来品は、フィルタエレメントを構成する部品（濾材、補強筒、両端部のエンドプレート等）を溶接、接着等による方法で固定しており、分解できなかった。 In the conventional product, components (filter medium, reinforcing cylinder, end plates at both ends, etc.) constituting the filter element are fixed by a method such as welding or adhesion, and cannot be disassembled.
また、分解できる構造を持つものでも下記各種課題を有していた：すなわち分解、組立が容易でない；また、組立後の気密性維持が不十分になり易い；エレメント内部の形状が複雑なため濾材の洗浄が困難；重量が重いため遠心分離による洗浄方法を実施する際に装置が高価になる；濾材に接した補強筒を配置すると逆流洗浄の際に洗浄液が直接濾材に届かず洗浄性が悪い；エレメントを廃棄する際に部品の再利用ができず、コスト面、環境負荷面で不利；等々である。 In addition, even if it has a structure that can be disassembled, it has the following various problems: That is, disassembly and assembly are not easy; and airtightness maintenance after assembly is likely to be insufficient; Cleaning is difficult; equipment is expensive due to its heavy weight. When a reinforcing cylinder in contact with the filter medium is placed, the cleaning liquid does not reach the filter medium directly during backwashing, resulting in poor cleanability. The parts cannot be reused when the element is discarded, which is disadvantageous in terms of cost and environmental load;
特許文献１及び２に記載の発明は共に「フィルター装置」に関するものであるが、いずれも本考案とは構成を異にする。
本考案は、濾材と補強筒の分離と再組立が容易にでき、組立て後に十分な密封性が確保される濾過装置を提供することを目的とする。 It is an object of the present invention to provide a filtration device that can easily separate and reassemble the filter medium and the reinforcing cylinder and ensure sufficient sealing after the assembly.
上記の課題は、被濾過流体から外圧を受ける濾材筒と、その内側に挿入されて濾材筒を支え、かつ濾過後流体の流出路として機能する補強筒とを具えてなり、当該濾材筒及び補強筒の間がパッキングを介して分離可能に封止されることを特徴とする濾過装置、により解決される。 The above-described problem includes a filter medium cylinder that receives external pressure from a fluid to be filtered, and a reinforcing cylinder that is inserted inside the filter medium cylinder to support the filter medium cylinder and functions as an outflow path for the filtered fluid. This is solved by a filtration device characterized in that the cylinders are separably sealed through packing.
上記濾過装置は分解、再組立が容易で、再組立後も密封性が高い。濾材自体の形状が単純かつ軽量で補強筒から分離できるため、遠心分離による洗浄を有効に実施でき、簡便な逆洗装置でも洗浄液が十分に濾材に届き、有効な洗浄効果を期待できる。また洗浄による再利用ができなくなった後も、濾材以外の部品は再利用が可能であり、コスト面、環境負荷面で有利である。 The filtration device can be easily disassembled and reassembled, and has high sealing performance after reassembly. Since the shape of the filter medium itself is simple and lightweight and can be separated from the reinforcing cylinder, cleaning by centrifugation can be carried out effectively, and even with a simple backwash device, the cleaning liquid can reach the filter medium sufficiently and an effective cleaning effect can be expected. In addition, even after the cleaning cannot be reused, parts other than the filter medium can be reused, which is advantageous in terms of cost and environmental load.
