【発明の詳細な説明】
本発明は例えば熱処理炉の前後工程としての機械油或い
は熱処理油等のような油脂を除去する油脂の真空脱脂装
置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vacuum degreasing apparatus for oils and fats, which removes oils and fats such as machine oil or heat treatment oil used before and after a heat treatment furnace.
従来の脱脂方法としてトリクロールエチレン等の有機溶
剤を使用するものとアルカリ水溶液を使用するものが一
般的である。有機溶剤の場合には蒸気化、噴腿、液洗い
方式とあるが人体への有害と作業環境の汚染が問題であ
り、アルカリの場合には排水規制等の問題をかかえてい
る。Conventional degreasing methods generally use organic solvents such as trichlorethylene and aqueous alkaline solutions. In the case of organic solvents, there are vaporization, spray, and liquid washing methods, but they pose problems of being harmful to the human body and contaminating the working environment, and in the case of alkalis, there are problems such as drainage regulations.
他の方法として品物に付着した油を燃焼させて除去する
バーンオフ方式があるが、５００℃以上で熱処理を行う
前工程としては使用出来るが、それより低温で熱処理す
る場合には使用出来ない。これは品物自身がバーンオフ
により温度が上る為である。Another method is the burn-off method, which burns and removes the oil adhering to the product, but it can be used as a pre-process for heat treatment at temperatures above 500°C, but cannot be used for heat treatment at lower temperatures. This is because the temperature of the item itself increases due to burn-off.
不発明考案はこれらの問題点を解決する装置であって、
人体に有害な有機溶剤や、排水処理に問題があるアルカ
リの使用をやめることと、どの脱脂工程にも応用出来る
ことを第１目的とする。さらに従来の方式では付着油の
回収は出来なかったが本装置では蒸気化した油を再液化

する。The non-inventive device is a device that solves these problems,
The primary goals are to eliminate the use of organic solvents that are harmful to the human body and alkalis that pose problems in wastewater treatment, and to be able to be applied to any degreasing process. Furthermore, although it was not possible to recover adhering oil using conventional methods, this device aims to recover vaporized oil by re-liquefying it and making it possible to regenerate it as fuel.

な燃焼排ガスの利用もできるものとなった。For this reason, the present invention is designed to separate the shower room from a shower room that is surrounded by a door or a partition wall and has a spray device that sprays light oil such as light oil or furnace oil onto the workpiece covered with oil. We provide vacuum degreasing equipment for oils and fats, which includes a warming room with a low-temperature heating device, a vacuum chamber that is combined with the warming room or installed separately, and is fully connected with a vacuum exhaust device and an oil mist trap for collecting oil and fats, and is capable of reducing flash points and ignition. For workpieces that have high-temperature oils and fats attached to them, we spray light oil like that in front of a furnace or a light oil in a trenchless shower room, and then send it to a heating chamber that also serves as a vacuum degreasing device. The present invention provides an apparatus that can carry out low-temperature preheating to raise the temperature in advance, and then perform complete degreasing using the vapor pressure of oils and fats of various properties in vacuum using a vacuum degreasing apparatus. Therefore, there is no need to use organic solvents that are harmful to the human body or alkaline agents that pose problems in wastewater treatment, and the oil can be recovered and reused using the oil mist trap. In addition, since the temperature of the heating chamber can be kept at a low temperature, it is now possible to utilize combustion exhaust gas, for example, from a heat treatment furnace to which this apparatus is attached.
