[Industrial applications]

本考案は、ダイキャストマシンの製品の型離れをよくするために使用される離型剤溶液の再生利用に関するものである。 The present invention relates to the recycling of a release agent solution used for improving the mold release of a product of a die casting machine.

【０００２】[0002]

[Prior art]

ダイキャストマシンに使用される離型剤溶液は、一度使用すると機械自体の油が混入して廃液として戻される。従来、その混入した油の除去方法には次のようなものがあった。（イ）油吸着シートだけで油除去をするもの。（ロ）油混入液を水面に静かに流入させ、浮上油の油膜だけをオーバーフローさせ油回収し除去するもの。（ハ）フロート式ゲートで比重差により浮上油だけを回収し除去するもの。するもの。（ニ）渦流で水を周辺に排除しながら、油膜だけを集積しポンプで吸引し除去するもの。（ホ）交流電流を液中の電極間に流し、油滴を凝集させ、比重差によって分離させ除去するもの。 Once used, the mold release agent solution used in the die-cast machine is mixed with the oil of the machine itself and returned as a waste solution. Conventionally, the following methods have been used to remove the mixed oil. (B) Oil removal using only the oil adsorption sheet. (B) A method in which the oil-mixed liquid is allowed to gently flow into the surface of the water, and only the oil film of the floating oil is allowed to overflow to recover and remove the oil. (C) A float type gate that collects and removes only the floating oil due to the difference in specific gravity. What to do. (D) A device that collects only the oil film and removes it by pumping it while removing water to the surroundings by vortex flow. (E) A method in which an alternating current is passed between electrodes in a liquid to agglomerate oil droplets and separate and remove them due to the difference in specific gravity.

[Problems to be solved by the device]

これは次のような欠点があった。（イ）油吸着シートだけで混入油を除去しようとするものは、シートの吸着量に限界があり、連続的に流れてくる廃液には、能力が小さすぎるのと、いつ吸着の限界なのかはっきりしないために使用出来ない。（ロ）油混入液の水面に浮上する油だけをオーバーフローやフロート式ゲートで回収するもの、そして、渦流利用の集積油膜をポンプで吸引し除去するものは、混入油の流量が多く、液面の変動の激しいものには、除去が不完全となって再生液として利用出来ない。（ハ）交流電流を液中の電極間に流して油滴を凝集させて除去するものは、離型剤としての主要成分まで除去してしまうために、そのままの液では使用出来ない。 This had the following drawbacks. (B) In the case where the oil adsorption sheet is used only to remove the mixed oil, the adsorption amount of the sheet is limited, and the capacity of the continuously flowing waste liquid is too small. It cannot be used because it is not clear. (B) The one that collects only the oil floating on the water surface of the oil-mixed liquid with an overflow or float-type gate, and the one that sucks and removes the accumulated oil film using vortex flow with a pump has a large flow rate of the mixed oil. If the liquid level fluctuates significantly, the removal is incomplete and it cannot be used as a regenerating liquid. (C) A method in which an AC current is passed between electrodes in a liquid to agglomerate and remove oil drops cannot remove the major components as a release agent, and therefore cannot be used as it is.

[Means for Solving the Problems]

廃液処理槽（２）に設けた流出口（５）からは、濃厚油混入液（３）を、第１仕切板（７）を潜った希釈油混入液（４）だけを、ろ過装置（１０）を通過させ、塵や油を吸着除去し、ろ過液（１２）とする。ろ過液（１２）の中のエマルジョン化された更に微粒の油分は、浮上分離液（１３）として中間受け槽（８）へと戻される。浮上分離しない第２仕切板（１４）を潜った液だけを再生液（１５）とする。以上のような構成よりなる離型剤溶液の再生装置である。 From the outflow port (5) provided in the waste liquid treatment tank (2), the concentrated oil mixed liquid (3) and only the diluted oil mixed liquid (4) which has dipped in the first partition plate (7) are filtered through the filtering device (10). ) To adsorb and remove dust and oil to obtain a filtrate (12). The further emulsified oil particles in the filtrate (12) are returned to the intermediate receiving tank (8) as the floating separation liquid (13). Only the liquid submerged in the second partition plate (14) which does not float and separate is used as the regenerating liquid (15). This is a device for regenerating a release agent solution having the above configuration.

[Action]

使用済廃液（１）は廃液処理槽（２）にて、濃厚油混入液（３）と希釈油混入液（４）に分離される。油除去の不完全な希釈油混入液（４）は、ポンプ（９）にて、ろ過装置（１０）を通過させた上で、ろ過液貯槽（１１）へと送られる。ろ過液貯槽（１１）で液中にエマルジョン化さた更に微粒の油分を含む浮上分離液（１３）を上面からオーバーフローさせて戻す。第２仕切板（１４）を潜った液は、再利用可能な再生液（１５）となる。 The used waste liquid (1) is separated into a concentrated oil mixed liquid (3) and a diluted oil mixed liquid (4) in the waste liquid treatment tank (2). The diluted oil mixed liquid (4) with incomplete oil removal is sent to the filtrate storage tank (11) after passing through the filtration device (10) by the pump (9). The levitation separated liquid (13) further emulsified in the liquid in the filtrate storage tank (11) and containing fine oil particles is overflowed from the upper surface and returned. The liquid that has dipped in the second partition plate (14) becomes a reusable regenerating liquid (15).

【Example】

以下に本考案の実施例について説明する。（イ）廃液処理槽（２）内に使用済廃液（１）を入れる。（ロ）廃液処理槽（２）内に於いて、使用済廃液（１）の濃厚油混入液（３）と希釈油混入液（４）は分離され、比重差により流出口（５）からは、濃厚油混入液（３）が油溜槽（６）に入り、希釈油混入液（４）は中間受け槽（８）へと流出する。（ハ）中間受け槽（８）の希釈油混入液（４）は、ポンプ（９）で、ろ過装置（１０）を通過させ、混入した油や塵を吸着させ、ろ過液（１２）として、ろ過液貯槽（１１）へと送られる。（ニ）ろ過液貯槽（１１）では、エマルジョン化された更に微粒の浮上分離液（１３）が比重差によって上面に溜まってくる。この液は中間受け槽（８）へと戻され、浮上せずに第２仕切板（１４）を潜った再利用可能な液だけを再生液（１５）として取り出すことが出来る。 An embodiment of the present invention will be described below. (A) Put the used waste liquid (1) into the waste liquid treatment tank (2). (B) In the waste liquid treatment tank (2), the concentrated oil mixed liquid (3) of the used waste liquid (1) and the diluted oil mixed liquid (4) are separated, and are separated from the outlet (5) by the difference in specific gravity. The concentrated oil mixed liquid (3) enters the oil reservoir tank (6), and the diluted oil mixed liquid (4) flows out to the intermediate receiving tank (8). (C) The diluted oil mixed liquid (4) in the intermediate receiving tank (8) is passed through the filtration device (10) by the pump (9) to adsorb the mixed oil and dust to obtain the filtered liquid (12). , To the filtrate storage tank (11). (D) In the filtrate storage tank (11), more finely divided floating liquid (13) is collected on the upper surface due to the difference in specific gravity. This liquid is returned to the intermediate receiving tank (8), and only the reusable liquid that has passed through the second partition plate (14) without floating and can be taken out as the regenerated liquid (15).

[Effect of device]

（イ）従来、ダイキャストマシンの製品の型離れをよくするために使用される離型剤溶液は、再利用すると製品に油による炭化した汚れ模様が付着し不良品が発生する。しかし混入する油や塵をほとんど除去すればこの種の不良品の発生はなくなった。（ロ）途中に、ろ過装置があるために、何等かの故障で大量の濃厚油が流入したとしても、再生液への影響はほとんどない。（ハ）また、使用した液が再利用出来るために、離型剤溶液の新液の量が激減するとともに、今まで廃棄していた廃液処分費もまた、激減させることが出来た。 (B) The mold release agent solution that has been conventionally used to improve the mold release of the product of the die cast machine, if reused, the carbonized dirt pattern due to the oil adheres to the product, resulting in defective products. However, if almost all the mixed oil and dust were removed, this kind of defective product would disappear. (B) Since there is a filtration device on the way, even if a large amount of concentrated oil flows in due to some failure, it has almost no effect on the regenerated liquid. (C) In addition, since the used liquid can be reused, the amount of new liquid of the release agent solution was drastically reduced, and the waste liquid disposal cost, which had been discarded until now, could also be drastically reduced.
