Description

本発明は、従来技術では強力な磁力を有する磁石を用いても、かつその他の手段を用いても完全除去出来なかった微細な磁性異物をほぼ１００％除去出来る湿式又は液体の流動体の微小磁性異物除去装置に関する。  The present invention is a wet or liquid fluid micromagnetism that can remove almost 100% of fine magnetic foreign matter that could not be completely removed by using a magnet having a strong magnetic force and other means in the prior art. The present invention relates to a foreign matter removing apparatus.

従来より微性磁性異物や微小異物を除去する装置としては各種のものが有り、例えば「特許文献１」の如きものや「非特許文献１」の如きものがあるが後に説明する本発明の如き湿式又は液体の流動体の微小磁性異物除去奘置は公知文献としては見当らない。  Conventionally, there are various devices for removing fine magnetic foreign matters and fine foreign matters, such as “Patent Document 1” and “Non-Patent Document 1”, but the present invention to be described later. There are no known methods for removing fine magnetic foreign substances in a wet or liquid fluid.

特開２００５−４０６９２号（図１）Japanese Patent Laying-Open No. 2005-40692 (FIG. 1) 図８に示す。As shown in FIG.

「特許文献１」の「特開２００５−４０６９２号」の「固定異物除去機能を有する濾過装置」は流動体の中の微細な異物を除去するもので外観的には本発明に似ている点もあるが磁力を使用するものでなくフィルタ的の機能を有するものである基本的構造において本発明とは相違するものである。  The “filtering device having a fixed foreign matter removing function” in “Japanese Patent Laid-Open No. 2005-40692” of “Patent Document 1” removes fine foreign matters in a fluid and is similar in appearance to the present invention. However, the present invention is different from the present invention in the basic structure that does not use magnetic force but has a filter function.

「非特許文献１」は図８に示す構造のものでありケース１内にバーマグネット３を微小隙間を介して挿入したものであるが、この構造では折角バーマグネット側に吸着した異物が流動体の流れに伴って剥がされて流出してしまう問題点があり、微小異物を除去することが出来ない。。  "Non-patent document 1" has a structure shown in FIG. 8 and is a case in which a bar magnet 3 is inserted into a case 1 through a minute gap. In this structure, foreign matter adsorbed on the bent bar magnet side is fluid. There is a problem that it is peeled off and flows out along with the flow of water, and it is impossible to remove minute foreign matters. .

一般に磁性異物は微小化するにつけ磁性が弱くなり吸着が出来にくい性質がある。また、磁性の弱い微小異物はマグネット吸着しても流動体によって引き剥がされてしまう問題点がある。
また、流動体の流速が速くなればなるほどまた粘度が高いほど前記の問題点の現象が強くなる。In general, magnetic foreign matter has a property that it becomes difficult to adsorb because it becomes weaker as it gets smaller. Further, there is a problem that minute foreign matter having weak magnetism is peeled off by the fluid even if the magnet is attracted.
In addition, the higher the flow rate of the fluid and the higher the viscosity, the stronger the phenomenon described above.

そこで後に詳しく説明するように本発明は突起部やケースとの間のクリアランスを狭くしたり、異物の滞留の効果と異物の分散の容易化を計って異物を磁界内に滞留させて異物除去効果を促進し、前記の問題点を解決することを目的とした異物除去装置を創案したものである。  Therefore, as will be described in detail later, the present invention reduces the clearance between the protrusions and the case, or makes the foreign matter stay in the magnetic field by making the foreign matter stay and the foreign matter easy to disperse, thereby removing the foreign matter. The present invention has been devised as a foreign matter removing apparatus for the purpose of accelerating the problem and solving the above-mentioned problems.

本発明は以上の目的を達成するために開発されたものであり、請求項１の発明は、磁性異物を含む流動体内の数１００ｎｍ〜数十μｍ以下の微小な磁性異物を除去出来る異物除去装置であって、該装置は、前記流動体の通過する通路とその入口部及び出口部を有するケースと、該ケース内に挿入され外面に複数の突起部を併設し内部に突起部の直前又は直前の近傍に配置されるように構成した磁極を併設したバーマグネットを有するアウターパイプ（鞘管）又は、磁極を併設し磁極の直後又は直後の近傍、かつ外面に複数の突起部を併設する突起付のバーマグネットを有するものからなり、前記突起部は、前記磁極に吸着した前記微小な磁性異物が前記流動体によって剥離される事を防ぐために形成される垂直面又はほぼ垂直な面からなる正面側と、前記流動体が前記突起部を通過する際、次の前記磁極に前記微小な磁性異物が吸着しやすくなるように前記流動体内の前記微小な磁性異物が分散されやすくするために形成される傾斜面からなる背面側とからなり、前記磁極に前記微小な磁性異物が吸着されやすくなるように前記突起部の頂点と前記ケースの内面との間には微小な隙間が形成されるものからなることを特徴とする。  The present invention has been developed to achieve the above object, and the invention of claim 1 is a foreign substance removing apparatus capable of removing minute magnetic foreign substances of several hundred nm to several tens of micrometers or less in a fluid containing magnetic foreign substances. The apparatus includes a case having a passage through which the fluid passes, an inlet portion and an outlet portion thereof, and a plurality of protrusions which are inserted into the case and provided on the outer surface, and immediately before or immediately before the protrusions. An outer pipe (sheath tube) having a bar magnet with a magnetic pole arranged so as to be arranged in the vicinity of the magnetic pole, or a protrusion with a plurality of protrusions on the outer surface immediately after or near the magnetic pole. The protrusion has a vertical surface or a substantially vertical surface formed to prevent the minute magnetic foreign matter adsorbed on the magnetic pole from being separated by the fluid. And when the fluid passes through the protrusion, the minute magnetic foreign matter in the fluid is easily dispersed so that the fine magnetic foreign matter is easily attracted to the next magnetic pole. A minute gap is formed between the apex of the protrusion and the inner surface of the case so that the minute magnetic foreign matter is easily attracted to the magnetic pole. It is characterized by becoming.

本発明の請求項１の湿式又は液体の流動体の微小磁性異物除去装置によれば、入口部と出口部を有するケース内に複数の突起部を併設したアウターパイプやバーマグネットを配設しこの突起部の前面側に垂直面又はほぼ垂直な面（垂直面等と仮称する）を形成し流動体の滞留時間を促進すると共に背面側に傾斜面を形成し異物の分散を促進させ異物の除去の効率化を計ると共にケースとのクリアランスを微小化して流動体の流速を制限し、更に垂直面等を磁極の直後又は直後の近傍に配設して吸着した異物の引き剥きを防止する効果を上げることが出来る。
また、アウターパイプの構造を設けることにより異物の清掃作業の効果を計ることが出来る。According to the wet magnetic or liquid fluid fine magnetic foreign matter removing device of claim 1 of the present invention, an outer pipe or bar magnet provided with a plurality of protrusions is provided in a case having an inlet portion and an outlet portion. A vertical surface or a substantially vertical surface (referred to as a vertical surface, etc.) is formed on the front side of the protrusion to promote the residence time of the fluid, and an inclined surface is formed on the back side to promote the dispersion of foreign materials and remove foreign materials. In addition, the flow rate of the fluid is limited by minimizing the clearance with the case, and the vertical surface is disposed immediately after or near the magnetic pole to prevent the adhering foreign matter from being peeled off. Can be raised.
Moreover, the effect of the foreign material cleaning work can be measured by providing the structure of the outer pipe.

以下、本発明の湿式又は液体の流動体の微小磁性異物除去装置の実施の形態を図面を参照して詳述する。  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a wet or liquid fluid minute magnetic foreign matter removing apparatus according to the present invention will be described below in detail with reference to the drawings.

図１に示すように、本発明の湿式又は液体の流動体の微小磁性異物除去装置１００は、細長なケース１とこの中に収納されているアウターパイプ（鞘管）２と図示では明確ではないがアウターパイプ２内に密接して収納されているバーマグネット３等とから構成されている。  As shown in FIG. 1, a wet or liquid fluid fine magnetic foreign matter removing apparatus 100 according to the present invention is not clearly shown in the drawing with an elongated case 1 and an outer pipe (sheath tube) 2 housed therein. Is composed of a bar magnet 3 and the like housed in close contact with the outer pipe 2.

図２はケース１の全体構造を示すものである。ケース１は細長なパイプ部１ａと流動体（図略）の出入する入口部１ｂと出口部１ｃとを有し、パイプ部１ａは一方側（図示では左側）に開放口１ｄが設けられている。  FIG. 2 shows the overall structure of the case 1. The case 1 has an elongated pipe portion 1a, an inlet portion 1b through which a fluid (not shown) enters and exits, and an outlet portion 1c. The pipe portion 1a has an opening 1d on one side (left side in the drawing). .

図３に示すように、アウターパイプ２はケース１の開放口１ｄから挿入される細長なパイプ状のものからなり、その軸部２ａには突起４ａを頂部に形成する突起部４がリング状に等間隔で多数個配列されている。また、アウターパイプ２はその一端（図示では右側）が閉止され他端（図示では左側）は開放されたものでケース１内の所定位置に挿入されるようにフランジ２ｂが設けられ他端には内部に収納される図４のバーマグネットの挿入位置を決めるためのフランジ２ｃが形成されている。  As shown in FIG. 3, the outer pipe 2 is an elongated pipe inserted through the opening 1d of the case 1, and a projection 4 is formed in a ring shape on the shaft 2a. Many are arranged at equal intervals. The outer pipe 2 is closed at one end (right side in the figure) and open at the other end (left side in the figure). The outer pipe 2 is provided with a flange 2b so as to be inserted into a predetermined position in the case 1, and at the other end. A flange 2c for determining the insertion position of the bar magnet of FIG. 4 housed inside is formed.

図４は図３のアウターパイプ２内に挿入されるバーマグネット３を示す。このバーマグネット３は図略されているが磁極５（図６）とマグネット６とを交互に配置したものからなり、アウターパイプ２への挿入位置を決めるためのフランジ３ａと把持部３ｂとを有するものからなる。  FIG. 4 shows the bar magnet 3 inserted into the outer pipe 2 of FIG. Although this bar magnet 3 is omitted in the drawing, the bar magnet 3 is formed by alternately arranging magnetic poles 5 (FIG. 6) and magnets 6, and has a flange 3a and a gripping portion 3b for determining an insertion position into the outer pipe 2. Consists of things.

図５は図１の丸印のＡ部の拡大図であり本発明の主要部の構造の一実施例を示すものである。アウターパイプ２には図示のように外周から出っ張り頂部に鋭角に突出する突起４ａを有する突起部４が複数個等間隔で配列される。この突起部４は流動体の流れ方向の前面側に垂直面等有し後方側に傾斜面を有するほぼ垂直の三角形の如き形状からなる。また、この突起４ａとケース１の内面との間には微小隙間７が形成されている。また、アウターパイプ２の内部には図４に示したバーマグネット３が密接して挿入されている。  FIG. 5 is an enlarged view of a portion A indicated by a circle in FIG. 1, and shows an embodiment of the structure of the main part of the present invention. As shown in the figure, a plurality of protrusions 4 having protrusions 4a protruding at an acute angle at the top of the outer pipe 2 are arranged at equal intervals. The protrusion 4 has a shape like a substantially vertical triangle having a vertical surface or the like on the front side in the flow direction of the fluid and an inclined surface on the rear side. A minute gap 7 is formed between the projection 4 a and the inner surface of the case 1. Further, the bar magnet 3 shown in FIG. 4 is closely inserted into the outer pipe 2.

図６は本発明の作用を示すものである。ケース１内に入口部１ｂにより導入された磁性異物を含む流動体はまず垂直面等に当り、図６に示すように滞留１１が生じ流動体の磁性異物９が磁極５に吸着する。次に、流動体は突起４ａとケースとの間の微小隙間７を通過するがこの際に図示のように渦流８が発生する。この渦流８の発生と突起部４の傾斜面により流動体内の磁性異物９が分散され次の突起部４の垂直面等に当り磁極５に吸着される。この現象により湿式又は液体の流動体の磁性異物９が除去される。この分散された磁性異物９は図示のようにその根本に吸着される。この分散された磁性異物９は突起部４の下方に磁極５が配置されているためアウターパイプ２側に強く吸着して剥がされることなく、結果として流動体は磁性異物９を分離した状態で出口部１ｃから吐出されることになる。
この結果、従来技術では除去出来なかった微小の磁性異物９が除去されると共に更に遥かに小さい磁性異物９も流動体から除去されることになる。
以上のように、本発明の湿式又は液体の流動体の微小磁性異物除去装置１００によれば、従来技術にない磁性異物９の除去が可能となる素晴らしい効果を上げることが出来る。FIG. 6 shows the operation of the present invention. The fluid containing the magnetic foreign matter introduced into the case 1 by the inlet 1b first hits a vertical surface or the like, and a stay 11 is generated as shown in FIG. Next, the fluid passes through the minute gap 7 between the protrusion 4a and the case. At this time, a vortex 8 is generated as shown in the figure. Due to the generation of the vortex 8 and the inclined surface of the protrusion 4, the magnetic foreign matter 9 in the fluid body is dispersed and hits the vertical surface of the next protrusion 4 and is attracted to the magnetic pole 5. Due to this phenomenon, the magnetic foreign matter 9 of the wet or liquid fluid is removed. The dispersed magnetic foreign matter 9 is adsorbed to the root as shown in the figure. Since the dispersed magnetic foreign matter 9 has the magnetic pole 5 disposed below the protrusion 4, it is strongly adsorbed to the outer pipe 2 side and is not peeled off. As a result, the fluid exits with the magnetic foreign matter 9 separated. It will be discharged from the part 1c.
As a result, the minute magnetic foreign matter 9 that could not be removed by the prior art is removed, and a much smaller magnetic foreign matter 9 is also removed from the fluid.
As described above, according to the fine magnetic foreign matter removing apparatus 100 of the wet or liquid fluid of the present invention, it is possible to obtain a great effect that enables the removal of the magnetic foreign matter 9 not present in the prior art.

図７は実施例１とはやや相異する湿式又は液体の流動体の微小磁性異物除去装置の部分的断面図を示す。
このものは実施例１のようにアウターパイプ２に突起部４を設けたものではなく、磁石そのものに突起部４を形成したものである。即ち、突起付磁石１０を設けたものである。この突起付磁石１０も前記のバーマグネット３の磁力と同様に高い磁性力を有するものである。
この突起付磁石１０の突起部４の突起４ａをケース１の内面に微小隙間７を介して配置する事により実施例１とほぼ同様の効果を上げる事が出来る。なお、微小隙間としては、例えば１ｍｍ程度のものからなる。なお、このものには図示のように磁極５が併設されておりこのバーマグネットは突起付のバーマグネットとも言うべきものである。FIG. 7 shows a partial cross-sectional view of a wet or liquid fluid minute magnetic foreign matter removing device that is slightly different from the first embodiment.
In this embodiment, the protrusion 4 is not provided on the outer pipe 2 as in the first embodiment, but the protrusion 4 is formed on the magnet itself. That is, the magnet 10 with protrusions is provided. This protruding magnet 10 also has a high magnetic force similar to the magnetic force of the bar magnet 3 described above.
By arranging the projection 4a of the projection 4 of the magnet with projection 10 on the inner surface of the case 1 via the minute gap 7, it is possible to obtain substantially the same effect as in the first embodiment. Note that the minute gap is, for example, about 1 mm. In this case, as shown in the figure, a magnetic pole 5 is also provided, and this bar magnet should be called a bar magnet with protrusions.

本発明は、以上の内容のものからなるが、その内容は以上のものに限定するものではなく、同一技術的範疇のものが適用されることは勿論である。  The present invention is composed of the above contents, but the contents are not limited to the above contents, and those of the same technical category are of course applied.

本発明は、磁性異物を含む流動体の全てから微小異物を除去する効果があり、構造も簡単であり、適用範囲は広く、利用可能性は極めて高い。  The present invention has an effect of removing minute foreign matters from all of the fluid containing magnetic foreign matters, has a simple structure, has a wide range of applications, and is extremely useful.
