【発明の詳細な説明】
この発明は、切削油等の液体中に混入した鉄粉
等の磁性金属粉を磁力を利用して除去・搬出し、
良好な清浄液となす汚液清浄方法に関する。[Detailed Description of the Invention] This invention utilizes magnetic force to remove and transport magnetic metal powder such as iron powder mixed into liquid such as cutting oil.
This invention relates to a dirty liquid cleaning method using a good cleaning liquid.
切削油、洗い油等の浄化および混入物の搬送を
行なう装置には、およそ、外周に複数個の磁石を
貼着した内筒とこれを囲繞する非磁性材からなる
外筒より構成される回転ドラムを、磁性金属粉の
混入した液体中に浸漬し、内筒の磁石の磁力によ
り外筒に磁性金属粉を吸着し、ドラムを回動させ
該ドラム周面に接して設けられている掻板により
掻取る方式が多く用いられている。 Equipment for purifying cutting oil, washing oil, etc. and transporting contaminants generally consists of an inner cylinder with multiple magnets attached to its outer periphery and an outer cylinder made of non-magnetic material surrounding it. The drum is immersed in a liquid mixed with magnetic metal powder, the magnetic metal powder is attracted to the outer cylinder by the magnetic force of the magnet in the inner cylinder, and the drum is rotated to create a scratching plate that is provided in contact with the circumferential surface of the drum. A method of scraping is often used.
従来の回転ドラムは、その一例を示すと外筒と
内筒が同軸でさらに内筒は固定であるため、外筒
円周に作用する磁力は一定で全周に等しい構成と
なり、外筒表面に吸着された磁性金属粉を掻取る
には磁力を上まわる力が必要になり、同金属粉の
剥離は容易ではない。従つて、この回転ドラムを
複数個用い多段に配置し、液槽に浸漬したドラム
の外筒表面に吸着された金属粉を、隣接する他ド
ラムの外筒表面に移動吸着させて、液体に混入し
た金属粉の除去、搬送を行なう場合にはドラム間
における金属粉の移動が不十分となる。 For example, in a conventional rotating drum, the outer cylinder and the inner cylinder are coaxial, and the inner cylinder is fixed, so the magnetic force acting on the outer cylinder circumference is constant and equal to the entire circumference, and the magnetic force is applied to the outer cylinder surface. Scraping off the adsorbed magnetic metal powder requires a force that exceeds the magnetic force, and it is not easy to peel off the magnetic metal powder. Therefore, by using a plurality of these rotating drums and arranging them in multiple stages, the metal powder adsorbed on the outer cylinder surface of the drum immersed in the liquid tank is moved and adsorbed to the outer cylinder surface of the adjacent drum, and mixed into the liquid. When removing and transporting the metal powder, the movement of the metal powder between the drums becomes insufficient.
この問題を解決するため種々の提案がなされて
いる。例えば、内筒外周の一部に磁石を設けずに
外筒に磁力が作用しない部分を作り、その位置で
隣接するドラムに金属粉を移動吸着させる構成の
ものがある。しかし、内筒が固定で外筒が回転す
るため金属粉を外筒上で磁力の作用しない部分ま
ですべり移動させることになり、磁力と摩擦抵抗
により金属粉の回転移動が容易でない。 Various proposals have been made to solve this problem. For example, there is a structure in which a part of the outer circumference of the inner cylinder is not provided with a magnet to create a part where no magnetic force acts on the outer cylinder, and the metal powder is moved and attracted to the adjacent drum at that position. However, since the inner cylinder is fixed and the outer cylinder rotates, the metal powder has to slide to a portion of the outer cylinder where magnetic force does not act, and rotational movement of the metal powder is not easy due to magnetic force and frictional resistance.
そこで、上記欠点を解消するドラムを本発明者
等は思考し、該ドラムを複数個隣接構成したマグ

なした。 Therefore, the inventors of the present invention devised a drum that would eliminate the above-mentioned drawbacks, and constructed a magnetic roller conveyor in which a plurality of such drums were arranged adjacent to each other, as shown in FIG.
The system is such that the dirty liquid is introduced from above the tank 1, the magnetic metal powder is adsorbed and carried out at the upper part of the conveyor, and the clean liquid is sent out by the pump 3 at the lower part.

で回転させるようになつている。従つて、外筒６
表面の磁力は、外筒６内面に磁石４が最も近い部
分で磁力が強く、その反対側で最も弱くなるよう
に構成されている。 The rotating drum 2 includes an inner cylinder 5 having a magnet 4 on its surface, and an outer cylinder 6 made of a non-magnetic material surrounding the inner cylinder 5.
The rotational axis center b of the inner cylinder 5 is eccentric to the rotational axis center a of the outer cylinder 6, and the distance between the surface of the magnet 4 provided on the surface of the inner cylinder 5 and the inner surface of the outer cylinder 6 is changed. The inner tube 5 and the outer tube 6 are rotated in the same direction and at substantially the same speed. Therefore, the outer cylinder 6
The magnetic force on the surface is configured such that the magnetic force is strongest at the portion where the magnet 4 is closest to the inner surface of the outer cylinder 6, and is weakest at the opposite side.
このような回転ドラム２を図示の如く、各々、
磁力の最も強い外筒６表面上で金属粉を吸着し、
磁力の最も弱い外筒６表面上で金属粉を離脱する

でドラム７表面から掻取られる。 As shown in the figure, such rotating drums 2 are each
Adsorbs metal powder on the surface of the outer cylinder 6, which has the strongest magnetic force,
The two parts are arranged adjacent to each other to form a magnetic roller conveyor so that the metal powder is separated from the surface of the outer cylinder 6 where the magnetic force is the weakest. While passing through the upper surface of the drum 2 or between the drums, it is well adsorbed and transferred to the upper scraping drum 7, where it is scraped onto the scraping plate 8.
It is scraped off from the surface of the drum 7.
しかしながら、非常に微細な微性金属粉あるい
は非磁性物はドラム２間を流れにつれて抜けるこ
とがあり、一度抜けると除去することができず、
槽１下部に沈殿固着し、そのため清浄液を低質な
ものとなすばかりでなく、液の通路を塞いで流れ
を阻害したり、または無理な負荷が掛る等の問題
があつた。 However, very fine metal powder or non-magnetic substances may escape as they flow between the drums 2, and once they escape, they cannot be removed.
It precipitates and adheres to the lower part of the tank 1, which not only makes the cleaning solution of low quality, but also causes problems such as blocking the channel of the solution, obstructing the flow, and imposing an unreasonable load on it.
この発明は、かかる問題に鑑み、上記構造の回
転ドラムを用い、濾過、搬出効率にすぐれた汚液
清浄方法を提案することを目的としている。 In view of this problem, it is an object of the present invention to propose a dirty liquid cleaning method that uses a rotating drum having the above structure and has excellent filtration and discharge efficiency.

せることを特徴とする汚液清浄方法である。 That is, in this invention, the center of the rotational axis of the inner cylinder provided with a magnet on its surface is eccentric with respect to the center of the rotational axis of the outer cylinder made of a non-magnetic material surrounding the inner cylinder, and there is a gap between the inner peripheral surface of the outer cylinder and the magnet. A magnetic roller conveyor is used, which consists of drums in which inner and outer cylinders rotate in the same direction and are arranged adjacently in multiple stages in a desired direction, and the waste liquid is transferred to the conveyor. This method of cleaning dirty liquid is characterized in that the liquid is allowed to flow upward from the bottom through the drums, and the plurality of drums are synchronously rotated in the conveying direction so that magnetic metal objects are attracted to the lower surfaces of the drums and conveyed.
次に、この発明を詳述するため図面にもとづい

す。 FIG. 2 shows a state in which a magnetic roller conveyor in which a plurality of rotating drums 2 described in FIG. 1 are arranged adjacent to each other in multiple stages is installed in a tank 9.

の上部では常に良好な清浄液となり、ポンプ１２
にて送出される。 Now, as shown by arrow A, if the dirty liquid flows into the lower part of the conveyor and the rotary drums 2 are rotated clockwise, the metal powder in the dirty liquid will flow through the bottom surface of each rotating drum 2 or between the drums. It is well absorbed while passing through,
While being transferred, it is conveyed to the upper scraping drum 10, and is scraped off from the surface of the drum 10 by a scraping plate 11. In addition, even if very fine magnetic metal powder or non-magnetic material flows between the drums 2, it may become flocculated or bubbles may escape.
When the flow stops, etc., it descends again through the space between the drums 2, settles at the bottom of the conveyor, and can be adsorbed to the bottom surface of the drum 2 again. Therefore, there is always a good cleaning liquid at the top of the conveyor, and the pump 12
will be sent out.

出される。 In addition, in the figure, since the scraping drum 10 and several drums 2 in its vicinity are arranged in parallel at almost the same height, how much metal powder is scraped off from the surface of the drum 10 by the scraping plate 11? It falls and is discharged outside the tank 9 without any hindrance.

非常に有用なものとなる。 Furthermore, as shown in FIGS. 3 and 4, the magnetic metal powder and non-magnetic substances precipitated at the bottom of the tank 9 are
By installing the scraping conveyor 13 for carrying out the sludge, the sludge deposited at the bottom of the tank 9 can also be taken out, making it extremely useful as a contamination cleaning device for cutting/grinding fluids, etc.
