以下、本考案の異物除去用フィルタの実施の形態を図面を参照して詳述する。 Hereinafter, embodiments of the foreign matter removing filter of the present invention will be described in detail with reference to the drawings.
本実施例では板材として金属板を用いたが、板材に限定するものでなく、円筒や円錐やその他の形状のものにも適用される。また、材質は金属に限定するものではなく例えばチタンも適用される。
図１及び図２に示すように本考案における異物除去用フィルタ１００は金属板１とこの金属板に貫通形成される多数個の微細孔２とからなり、本実施例では金属板１の外周形状は円板状のものからなるが、勿論これに限定するものではなくこの異物除去用フィルタ１００が取り付けられる対手側の装置の形状に合わせたものからなる。
In this embodiment, a metal plate is used as the plate material. However, the present invention is not limited to the plate material, and can be applied to cylinders, cones, and other shapes. Further, the material is not limited to metal, and for example, titanium is also applied.
As shown in FIGS. 1 and 2, a foreign matter removing filter 100 according to the present invention comprises a metal plate 1 and a large number of fine holes 2 formed through the metal plate. In this embodiment, the outer peripheral shape of the metal plate 1 is shown. However, the present invention is not limited to this, and is not limited to this, and is formed according to the shape of the device on the other hand side to which the foreign matter removing filter 100 is attached.
この微細孔２の加工としては前記のような各種の加工手段では金属板１に変形や反り等の不具合が生じ易く精密なフィルタとしては不合格品となるためこの微細孔２の加工はエッチングによって加工される。 As for the processing of the fine hole 2, the various processing means as described above are liable to cause defects such as deformation and warping in the metal plate 1 and become a rejected product as a precise filter. Processed.
一般に金属板にエッチングで微細孔を加工する場合、このま微細孔の内径は金属板の板厚よりも大きいものしかできない。従って、金属板の板厚よりも小さい内径の微細孔の加工は無理となる。しかしながら、異物除去用フィルタ１００としてはその機能を発揮するためには極力小径の微細孔が必要になる。 In general, when fine holes are processed in a metal plate by etching, the inner diameter of the fine holes can only be larger than the thickness of the metal plate. Therefore, it is impossible to process fine holes having an inner diameter smaller than the thickness of the metal plate. However, the foreign matter removing filter 100 requires micro holes with a small diameter as much as possible in order to perform its function.
そこで本考案の異物除去用フィルタ１００は板厚の薄い一枚の金属板１ａにこの板厚よりもやや大径の微細孔２を加工し、この一枚の金属板１ａを多数枚（図２では３枚）重合することにより重合された金属板１の板厚よりも小径の微細孔２を形成することができる。 Therefore, in the foreign matter removing filter 100 of the present invention, fine holes 2 having a diameter slightly larger than the plate thickness are processed in one metal plate 1a having a thin plate thickness, and a large number of the metal plates 1a (FIG. 2). In this case, the fine holes 2 having a smaller diameter than the thickness of the polymerized metal plate 1 can be formed by polymerization.
微細孔２を設けた一枚の金属板１ａを複数枚重合させる方法としては色々の手段があるが、拡散接合によるものが最も望ましい。一枚の金属板１ａを複数枚重合させるための拡散接合の方法としては例えば前記した「特許文献２」が参考となり、精密な重合を行うことは可能である。 There are various means for polymerizing a plurality of single metal plates 1a provided with the fine holes 2, but diffusion bonding is most preferable. As a diffusion bonding method for polymerizing a plurality of one metal plate 1a, for example, the above-mentioned “Patent Document 2” can be referred to and precise polymerization can be performed.
以上のように、本考案の異物除去用フィルタ１００は薄板の金属板１ａを複数個重合させて一体化することにより金属板１の板厚よりも小径の微細孔２を形成することができ、所望の機能の異物除去用フィルタ１００を作ることができる。 As described above, the foreign matter removing filter 100 of the present invention can form the fine holes 2 having a smaller diameter than the thickness of the metal plate 1 by polymerizing and integrating a plurality of thin metal plates 1a. The foreign matter removing filter 100 having a desired function can be produced.
図３は以上の構造の異物除去用フィルタ１００の使用例の１つを示すものであり、図３の場合は磁石３を用いた異物除去装置２００に本考案の異物除去用フィルタ１００を装着したものを示す。この異物除去装置２００は異物を含有している液体や粉体の連通する通路４を形成するケース本体５とケース本体５の中間に挿脱可能に設けられる磁石（バーマグネット）３等とから形成される。
本考案の異物除去用フィルタ１００は図３に示すようにケース本体５の入口側に設けられるものからなる。ケース本体５の入口からケース本体内に導入された流動体は異物除去用フィルタ１００に衝突し、その微細孔２によって流動体に含まれている異物の大部分が除去される。一方、この微細孔２を通過した金属製の異物は磁石３により磁着除去される。以上によりケース本体５の出口側からは異物が除去された流動体が送出されて次工程側に送られることになる。
FIG. 3 shows one example of use of the foreign matter removing filter 100 having the above structure. In the case of FIG. 3, the foreign matter removing filter 100 of the present invention is attached to the foreign matter removing device 200 using the magnet 3. Show things. This foreign matter removing apparatus 200 is formed of a case main body 5 that forms a passage 4 through which liquid or powder containing foreign matters communicates, and a magnet (bar magnet) 3 that is detachably provided between the case main body 5 and the like. Is done.
The foreign matter removing filter 100 of the present invention is provided on the inlet side of the case body 5 as shown in FIG. The fluid introduced into the case body from the inlet of the case body 5 collides with the foreign matter removing filter 100, and most of the foreign matter contained in the fluid is removed by the fine holes 2. On the other hand, the metal foreign matter that has passed through the fine hole 2 is magnetically removed by the magnet 3. As described above, the fluid from which foreign matter has been removed is sent out from the outlet side of the case body 5 and sent to the next process side.
本考案は以上の構造のものからなるが、本考案の異物除去用フィルタは以上の内容のものに限定されるものではなく、同一技術的範疇のものが適用されることは勿論である。また、金属板は平板に限定するものではなく、前記のように円筒や円錐等の各種形状のものに適用される。 The present invention has the above-described structure, but the foreign matter removing filter of the present invention is not limited to the above-described contents, and the same technical category is of course applied. Further, the metal plate is not limited to a flat plate, and is applied to various shapes such as a cylinder and a cone as described above.
本考案の異物除去用フィルタは液体や粉体や流動体内の異物を除去する必要な装置にすべて適用可能でありその利用範囲は極めて広い。 The foreign matter removing filter of the present invention can be applied to any apparatus that needs to remove foreign matters in liquids, powders, and fluids, and its application range is extremely wide.
