Description
濾過カートリッジは、流体（液体または気体）のクリーニング媒体として幅広い応用分野で周知である。例えば、気体の場合、濾過カートリッジは、多孔性の紙または織布から作られるバッグに代わり気体から粒子を除去するという利点を備えている。 Filtration cartridges are well known in a wide range of applications as fluid (liquid or gas) cleaning media. For example, in the case of gas, filtration cartridges have the advantage of removing particles from the gas instead of bags made from porous paper or woven fabric.
工業設備では、過程で生じる煙霧の処理は、伝統的に数百または数千のバッグを収納できる集塵器により行われていた。これらのバッグは、その分野でいわれているように飽和し、または、目詰まりするので、定期的に新しいバッグと取り替えなければならない。今日、バッグは、次第に、濾過カートリッジ、特に、ひだ付き濾過エレメントが容器内でカートリッジの適切な密封を確実にする一対の端部部材により支持され、または、その間に支持された円筒状濾過カートリッジに置き換えられている。バッグを上回るこれらのカートリッジの１つの重要な利点は、濾過エレメントの表面積がバッグの約３倍から４倍であることである。これにより、これらの濾過カートリッジを備えた集塵器は多量の気体を処理することが可能となる。それから、集塵器は小さくでき、あるいは、メンテナンスや取り替えの前に長期間の使用が可能となる。この後者の利点は、集塵器のメンテナンスを実施するために設備を停止させる頻度が減少するので、生産性の点で重要になる。 In industrial equipment, the treatment of fumes generated in the process has traditionally been performed by dust collectors that can store hundreds or thousands of bags. These bags saturate or become clogged as said in the field and must be periodically replaced with new bags. Today, bags are increasingly on filtration cartridges, particularly cylindrical filtration cartridges in which pleated filtration elements are supported by or supported between a pair of end members that ensure proper sealing of the cartridge within the container. Has been replaced. One important advantage of these cartridges over the bag is that the surface area of the filter element is about 3 to 4 times that of the bag. Thereby, the dust collector provided with these filtration cartridges can process a large amount of gas. Then, the dust collector can be small or can be used for a long time before maintenance or replacement. This latter advantage is important in terms of productivity because the frequency of shutting down equipment to perform dust collector maintenance is reduced.
濾過カートリッジの選択または設計には、濾過カートリッジが稼動するときの最大温度を考慮しなければならない。一般的に、従来の濾過カートリッジは比較的低温である気体にだけ適する。比較的高温である気体用カートリッジは、かなり高価であるにも拘わらず、取り扱える最大気体温度に関して制限がある。現在、市販されている濾過カートリッジは、代表的には約２００℃までの気体に使用される。温度が高くなると濾過カートリッジは劣化する。多くの工業設備では高温で煙霧が発生するので、この制限は問題である。それで、集塵器に入る前に気体を冷却せざるを得なくなる。冷却は、高温な気体を周囲の空気で希釈することにより幅広く行われている。残念ながら、これでは、濾過すべき気体の量が増加し、結局、必要なカートリッジの数、つまり、集塵器のサイズが増大してしまう。 The choice or design of the filtration cartridge must consider the maximum temperature at which the filtration cartridge will operate. In general, conventional filtration cartridges are only suitable for gases that are relatively cold. Although relatively hot gas cartridges are quite expensive, there are limitations on the maximum gas temperature that can be handled. Currently, commercially available filtration cartridges are typically used for gases up to about 200 ° C. As the temperature increases, the filtration cartridge degrades. This restriction is problematic because many industrial installations generate fumes at high temperatures. Therefore, the gas must be cooled before entering the dust collector. Cooling is widely performed by diluting a hot gas with ambient air. Unfortunately, this increases the amount of gas to be filtered and eventually increases the number of cartridges required, ie the size of the dust collector.
一般的に２００℃の近くで観察される従来の濾過カートリッジの劣化は、たいてい、端部部材を作るために使用される材料から起こる。これらの端部部材は、通常、約２００℃以上に加熱されると損傷する高分子材料から作られる。そのような従来の濾過カートリッジの製造中に、濾過エレメントの一方の端部は、鋳型に入れられた液体高分子材料内に高分子材料が凝固するまで浸される。このために使用される典型的な高分子材料はエポキシやポリウレタンである。約２００℃以上の温度では、これらの高分子材料の機械的特性は劣化し、カートリッジが逆転した空気の衝撃により清浄されるときのように、機械的衝撃を受ければ、対応する部分が簡単に破壊されてしまうまでになる。 The degradation of conventional filtration cartridges, generally observed near 200 ° C., usually occurs from the material used to make the end members. These end members are typically made from polymeric materials that are damaged when heated above about 200 ° C. During the manufacture of such conventional filtration cartridges, one end of the filtration element is immersed in a liquid polymer material placed in a mold until the polymer material solidifies. Typical polymeric materials used for this purpose are epoxies and polyurethanes. At temperatures above about 200 ° C, the mechanical properties of these polymeric materials deteriorate and the corresponding parts are easily removed when subjected to mechanical impacts, such as when the cartridge is cleaned by the impact of reversed air. Until it is destroyed.
最大稼動温度を高めるために、濾過カートリッジ内に高分子材料の使用を避ける試みがなされている。セラミック材料が代わりとして示唆されている。あいにく、これらのセラミック材料の機械的衝撃に対する抵抗力は高分子物質の抵抗力より悪いことが分かった。 In order to increase the maximum operating temperature, attempts have been made to avoid the use of polymeric materials in the filtration cartridge. Ceramic materials have been suggested as an alternative. Unfortunately, it has been found that the resistance of these ceramic materials to mechanical impact is worse than that of polymeric materials.
重合体またはセラミックと比較すると、金属は、機械的特性がかなり良好である。しかしながら、主な問題は金属部分に濾過エレメントを取り付けることである。濾過エレメントは、通常、典型的には約２６０℃までの温度に対して耐性のあるひだ付き織布となっている。この最大温度は、たいていの金属の融点に比較して相対的に低い。例えば、アルミニウムは約６６０℃の融点を持つ。濾過エレメントの一部を溶融したアルミニウム内に直接浸けると、濾過エレメントは数秒で破壊するであろう。 Compared to polymers or ceramics, metals have considerably better mechanical properties. However, the main problem is attaching the filter element to the metal part. The filter element is typically a pleated woven fabric that is typically resistant to temperatures up to about 260 ° C. This maximum temperature is relatively low compared to the melting point of most metals. For example, aluminum has a melting point of about 660 ° C. If a portion of the filter element is immersed directly in molten aluminum, the filter element will break in seconds.
本発明は、金属端部部材を濾過エレメントに結合することを可能にする構成を提供することにより、従来技術で経験されている困難と欠点を減少させる。とりわけ、これにより、濾過カートリッジは機械的衝撃並びに高い稼動温度に対してより大きな抵抗力を持つようになる。 The present invention reduces the difficulties and disadvantages experienced in the prior art by providing a configuration that allows a metal end member to be coupled to a filtration element. In particular, this makes the filtration cartridge more resistant to mechanical shock as well as high operating temperatures.
本発明の他の特徴および利点は、添付図面と共に行われる好ましい実施例の以下の詳細な説明に述べられており、あるいは、この説明から明白となる。 Other features and advantages of the present invention are set forth in or are apparent from the following detailed description of the preferred embodiment taken in conjunction with the accompanying drawings.
図１は、本発明の好ましい実施例による金属端部部材（３０）を有する濾過カートリッジ（１０）を示す。図２は、それに代わる実施例を示す。本発明は、図示された実施例に限定されず、添付された請求の範囲を逸脱することなく、多くの他の実施例も考えられることに注意すべきである。 FIG. 1 shows a filtration cartridge (10) having a metal end member (30) according to a preferred embodiment of the present invention. FIG. 2 shows an alternative embodiment. It should be noted that the present invention is not limited to the illustrated embodiments, and that many other embodiments are possible without departing from the scope of the appended claims.
濾過カートリッジ（１０）は、濾過エレメント（２０）からなる。濾過エレメント（２０）は通常、多孔性織布、または、その均等物の形をしている。濾過エレメントは、全表面積を増大させるために、一般的にひだ付きの形状で提供される。しかしながら、本発明は、ひだ付きの濾過エレメントに限定されないことに注意すべきである。濾過エレメント（２０）の最も普通の形状は中空円筒として形成されるものである。 The filtration cartridge (10) consists of a filtration element (20). The filter element (20) is usually in the form of a porous woven fabric or its equivalent. Filter elements are generally provided in a pleated shape to increase the total surface area. However, it should be noted that the present invention is not limited to pleated filter elements. The most common shape of the filtration element (20) is that formed as a hollow cylinder.
濾過カートリッジ（１０）は、少なくとも１つの金属端部部材（３０）からなるが、たいていは、２つの金属端部部材（３０）が使用される。濾過エレメント（２０）が矩形であれば、４つの金属端部部材（３０）が存在するであろう。本発明によれば、濾過エレメント（２０）と金属端部部材（３０）間の結合は、延長バンド（４０）を使用して行われる。この延長バンド（４０）は濾過エレメント（２０）のエッジ（２２）に沿って取り付けられた第１の縦方向エッジ（４２）を有する。延長バンド（４０）は、濾過エレメント（２０）の長さを増大させるとともに、製造中に高温の金属と濾過エレメント（２０）が直接接触するのを避けるために使用される。 The filtration cartridge (10) consists of at least one metal end member (30), but usually two metal end members (30) are used. If the filter element (20) is rectangular, there will be four metal end members (30). According to the invention, the connection between the filter element (20) and the metal end member (30) is made using an extension band (40). The extension band (40) has a first longitudinal edge (42) attached along the edge (22) of the filtration element (20). The extension band (40) is used to increase the length of the filter element (20) and to avoid direct contact between the hot metal and the filter element (20) during manufacture.
延長バンド（４０）は、好ましくは、積層にできる材料から作られる薄い金属シートの帯の形をしている。そのような材料の例は、アルミニウムまたは、その合金、ステンレススチールまたはスチールである。同様に他の材料も使用できる。全ての場合において、材料は耐熱性でなければならず、このことは、材料が製造工程中に遭遇する最高温度に持ちこたえなければならないことを意味する。延長バンド（４０）の厚さは、好ましくは、２０μｍと５００μｍの間であり、幅は約５ｍｍと１５０ｍｍの間である。延長バンドの幅は、大部分、使用される材料の熱伝導率に基づいて計算されなければならない。材料の熱伝導率が低ければ小さい延長バンドを使用できる。 The extension band (40) is preferably in the form of a strip of thin metal sheet made from a material that can be laminated. Examples of such materials are aluminum or its alloys, stainless steel or steel. Other materials can be used as well. In all cases, the material must be heat resistant, which means that the material must withstand the highest temperatures encountered during the manufacturing process. The thickness of the extension band (40) is preferably between 20 μm and 500 μm and the width is between about 5 mm and 150 mm. The width of the extension band has to be calculated largely based on the thermal conductivity of the material used. Small extension bands can be used if the thermal conductivity of the material is low.
濾過エレメント（２０）を、ひだ付きに設計するときは、ひだを付ける前に延長バンド（４０）を濾過エレメントに結合しておくのが好ましい。このようにすれば、濾過エレメント（２０）にひだを付けるのと、延長バンド（４０）にひだを付けるのを同時に行うことができる。 When the filter element (20) is designed with pleats, it is preferred that the extension band (40) be coupled to the filter element prior to pleating. In this way, it is possible to simultaneously pleat the filter element (20) and pleat the extension band (40).
濾過エレメント（２０）と延長バンド（４０）との間の結合は、任意の適切な結合方法を使用して行われる。しかしながら、特に濾過エレメント（２０）が多孔性織布から成るならば、結合は、縫製を使用して行うのが好ましい。縫製糸（２４）のための材料の例は、金属、繊維ガラス、セラミックまたはテフロン（登録商標）である。同様に他の材料も使用できる。縫製糸（２４）を一列又は多数列に使用してもよい。また、延長バンド（４０）の第１のエッジ（４２）は、好ましくは、縫製を使用する時には濾過エレメント（２０）のエッジ（２２）と重なり合う。 The coupling between the filter element (20) and the extension band (40) is made using any suitable coupling method. However, it is preferred that the bonding be performed using sewing, particularly if the filter element (20) is made of a porous woven fabric. Examples of materials for the sewing thread (24) are metal, fiberglass, ceramic or Teflon. Other materials can be used as well. Sewing threads (24) may be used in one or multiple rows. Also, the first edge (42) of the extension band (40) preferably overlaps the edge (22) of the filter element (20) when sewing is used.
中空円筒として形成されるひだ付き濾過エレメント（２０）を有する濾過カートリッジ（１０）には、一般的に多孔性で剛性の内部コア（５０）、例えば、内部に同軸に配置される金属の円筒状支持メッシュが設けられる。濾過エレメント（２０）は、それ自体で十分な強度を持つのであれば、内部コア（５０）は不要であろう。けれども、内部コア（５０）は多孔性であると言われ、このことは、流体が内部コアを通って流れるか、その構成要素の間で流れることができることを意味する。内部コア（５０）を用いて２つの端部部材（３０）が堅固に結合され、濾過エレメント（２０）が支持される。種々の種類の内部コア（５０）を使用できることに注意しなければならない。例えば、内部コア（５０）は鋳造された両方の金属端部部材（３０）を結合する多数の延長バーから構成するようにすることができる。全ての場合において、材料は耐熱性でなければならず、このことは、材料が製造工程中に遭遇する最高温度に持ちこたえなければならないことを意味する。 A filtration cartridge (10) having a pleated filtration element (20) formed as a hollow cylinder generally includes a porous, rigid inner core (50), eg, a metal cylinder coaxially disposed therein. A support mesh is provided. If the filtering element (20) has sufficient strength by itself, the inner core (50) may not be necessary. However, the inner core (50) is said to be porous, meaning that fluid can flow through the inner core or between its components. The two end members (30) are firmly joined using the inner core (50) to support the filter element (20). It should be noted that various types of inner core (50) can be used. For example, the inner core (50) can be composed of a number of extension bars that join both cast metal end members (30). In all cases, the material must be heat resistant, which means that the material must withstand the highest temperatures encountered during the manufacturing process.
図１で示す実施例の濾過カートリッジ（１０）の製造中に、延長バンド（４０）の第２のエッジ（４４）は、金属鋳造端部部材（３０）を作るために鋳型内に入れられた溶融金属内に浸漬される。延長バンド（４０）を挿入する前あるいはその後で、溶融金属が鋳型内に注入される。続いて、延長バンド（４０）の第２のエッジ（４４）を溶融金属に埋め込ませた状態で溶融金属が凝固される。内部コア（５０）または他種の支持体が設けられるのであれば、その一方の端部も、溶融金属が凝固する前に、溶融金属内に浸漬される。 During manufacture of the example filtration cartridge (10) shown in FIG. 1, the second edge (44) of the extension band (40) was placed in a mold to make a metal cast end member (30). It is immersed in the molten metal. Before or after inserting the extension band (40), molten metal is injected into the mold. Subsequently, the molten metal is solidified with the second edge (44) of the extension band (40) embedded in the molten metal. If an inner core (50) or other type of support is provided, one end thereof is also immersed in the molten metal before the molten metal solidifies.
通常、各円筒状の濾過カートリッジ（１０）に対して２つの端部部材（３０）が存在するので、第２の金属鋳造端部部材（３０）は、第１の金属鋳造端部部材が凝固した後で製造される。第２の延長バンド（４０）は、その時点で濾過エレメント（２０）の反対側に既に取り付けられているようにするのが、好ましい。そのとき、全体の濾過カートリッジ（１０）は単に回転されるだけであり、第２の延長バンド（４０）が残った分量の溶融金属内に浸される。 Usually, there are two end members (30) for each cylindrical filtration cartridge (10), so the second metal cast end member (30) is solidified by the first metal cast end member. Manufactured after. The second extension band (40) is preferably already attached to the opposite side of the filter element (20) at that time. The entire filtration cartridge (10) is then simply rotated and the second extension band (40) is immersed in the remaining amount of molten metal.
金属鋳造端部部材（３０）を製造するために使用される溶融金属は、好ましくは、アルミニウムまたは、その合金を含む。アルミニウムを使用する利点は数多くある。例えば、アルミニウムは比較的溶融温度が低く、軽量で抵抗力が高い。しかし、合金を含む他種の金属も同様に使用できる。 The molten metal used to produce the metal cast end member (30) preferably comprises aluminum or an alloy thereof. There are many advantages to using aluminum. For example, aluminum has a relatively low melting temperature, light weight and high resistance. However, other types of metals including alloys can be used as well.
所望なら、金属鋳造端部部材（３０）または、その一部を形成するために使用される鋳型は、製造工程後に濾過カートリッジ（１０）に残存するように設計することができる。例えば、鋳型は溶融金属が注がれるカップ（６０）を備えることができる。カップ（６０）は、凝固後に金属鋳造端部部材（３０）の外部に残存し、一体となった部分を形成するように設計することができる。これは、有益であり、濾過カートリッジ（１０）の機械的特性を一層増大させるとともに、表面仕上げを良好にする。カップ（６０）は、好ましくは、スチールまたは任意の他の金属などの金属から作られる。 If desired, the metal casting end member (30), or the mold used to form a part thereof, can be designed to remain in the filtration cartridge (10) after the manufacturing process. For example, the mold can comprise a cup (60) into which molten metal is poured. The cup (60) can be designed to remain outside the cast metal end member (30) after solidification to form an integral part. This is beneficial and further increases the mechanical properties of the filtration cartridge (10) and provides a good surface finish. The cup (60) is preferably made from a metal such as steel or any other metal.
図２は、他の可能な実施例を示す。この実施例は本質的に多孔性で金属の内部コア（５０）を備えた円筒状の濾過カートリッジ用に使用される。この場合、延長バンド（４０）は第１の実施例と同様に濾過エレメント（２０）に縫製される。延長バンド（４０）は内部コア（５０）の対応する端部上で圧搾され、それにより、内部コアが持続的に変形される。この変形により、いくつかのタイプの延長バンド（４０）を内部コア（５０）上に好適に保持させることができるとともに、好ましいことに、金属ベルト（７０）あるいは類似の構成を用いて抵抗力を付加させることができる。対応する端部を密封するために、金属板（７２）が内部コア（５０）に溶接される。延長バンド（４０）は、特に濾過エレメント（２０）を溶接で発生する熱から保護する。 FIG. 2 shows another possible embodiment. This embodiment is used for a cylindrical filtration cartridge with an essentially porous, metallic inner core (50). In this case, the extension band (40) is sewn to the filter element (20) as in the first embodiment. The extension band (40) is squeezed on the corresponding end of the inner core (50), thereby permanently deforming the inner core. This deformation allows several types of extension bands (40) to be suitably retained on the inner core (50) and preferably provides resistance using a metal belt (70) or similar configuration. Can be added. A metal plate (72) is welded to the inner core (50) to seal the corresponding ends. The extension band (40) in particular protects the filter element (20) from the heat generated by welding.
理解できるように、金属端部部材（３０）を使用すると、濾過カートリッジ（１０）の最大稼動温度を増大させ、機械的衝撃に対する抵抗力を増大させることができる。この最大温度は、濾過エレメント（２０）に使用される材料に依存し、その結果、新規で適切な材料が見つけられるにしたがって、さらに高くなるであろう。 As can be appreciated, the use of the metal end member (30) can increase the maximum operating temperature of the filtration cartridge (10) and increase the resistance to mechanical shock. This maximum temperature depends on the material used for the filter element (20), and as a result will be higher as new and suitable materials are found.
