ある。The present invention provides a cleaning system for metals and other materials having a cleaning tank isolated from the outside air and its system, in which a distillation tank equipped with a heater is provided in the downstream path of the washing tank, and further below the distillation tank. A cooler and a recovery tank are sequentially installed in the path, a fresh liquid tank is installed in the path below the recovery tank to transfer and receive the solvent liquid from the recovery tank, and a clear liquid tank is installed in the path between the recovery tank and the fresh liquid tank. This is a recovery device for a solvent liquid for cleaning metal workpieces, characterized in that a vacuum pump is provided and a pipe is provided for delivering the solvent liquid from a fresh liquid tank to the cleaning tank.
次に本発明を図面の実施例について説明する。 Next, the present invention will be described with reference to embodiments shown in the drawings.
図面は本発明装置の一実施例のブロックＩＡである。The drawing shows a block IA of an embodiment of the device of the present invention.
まずワーク１を収容した洗浄槽２内を真空ポンプ４を介
して真空状態にする（第−丁一程）。First, the inside of the cleaning tank 2 containing the workpiece 1 is brought into a vacuum state via the vacuum pump 4 (step 1).

。Specifically, this is done by opening the valve 2, closing the valves Vl and V3, and operating the vacuum pump 4 to discharge the air in the cleaning tank 2 to the atmosphere via the fresh liquid tank 6b and the filter 7. be exposed. As a result, oils and fats existing in the recesses and gaps of the work l are pushed out together with the air in the cleaning tank.
ついで清液タンク６ｂと洗浄槽２間のバルブＶ１を開き
、バルブｖ２を閉じ、パイプ１０を経由して溶剤液をシ
ャワー栓３からワークｌに噴射する（第二工程）。Next, the valve V1 between the fresh liquid tank 6b and the cleaning tank 2 is opened, the valve V2 is closed, and the solvent liquid is injected from the shower plug 3 onto the work l via the pipe 10 (second step).
このとき、洗浄槽内は直前まで真空状態であるから、溶
剤液がワークの四部や隙間内にきわめて簡単かつ確実に
侵入することができ、さらに溶剤液によりワーク自体が
冷却されることとなる。At this time, since the inside of the cleaning tank is in a vacuum state until just before cleaning, the solvent liquid can enter the four parts and gaps of the workpiece very easily and reliably, and furthermore, the workpiece itself is cooled by the solvent liquid.
この第二工程において、噴射された溶剤液により油脂等

浄槽２の底部に貯留され１次の蒸気洗浄時の加熱蒸発に
備えることとなる。In this second step, oils and fats and the like are washed away with the sprayed solvent solution. The solvent solution injected onto the workpiece is stored at the bottom of the cleaning tank 2 in preparation for heating and evaporation during the primary steam cleaning.
つぎにバルブｖｌを閉じ、洗浄槽２の下部又は周辺をヒ
ーター９ａで加熱し、洗浄槽内に貯留された溶剤液を加
熱蒸発させ、この蒸気を洗浄槽内に充満させて、Ａ気洗
浄が行われる（第三工程）。Next, the valve vl is closed, the lower part or the surrounding area of the cleaning tank 2 is heated with the heater 9a, the solvent solution stored in the cleaning tank is heated and evaporated, the cleaning tank is filled with this vapor, and the A-air cleaning is performed. carried out (third step).
このへ気洗節には、溶剤液のハスが冷却されたワークに

柔らかくして強力な洗浄が行われる。During this air washing, the solvent solution comes into contact with the cooled workpiece, raising the temperature of the workpiece by 1-1, and the air is cooled and liquefied, and this action causes oil and fat on the surface of the workpiece to rise. It further softens and performs a powerful cleaning.

．． Close V7 and close valve V4. Open V5 and V6 and operate the vacuum pump 4 in this state to drain the distillation tank 5 and recovery tank 6.
This is done by discharging the air inside a through the fresh liquid tank 6b and the filter 7.

3 to transfer the dirty solvent solution in the cleaning tank 2 into the holding tank 5, and then open the valve V3. Close valve V5 and close valve V4. V
6, and this state f,! Heater 9b is used to heat the tank.
The distilled liquid entering and leaving the distillation tank 5 is liquefied by the cooler 8, and stored and recovered in the recovery tank 6a. At this time, since the inside of the recovery tank 6a is in a vacuum state, the liquefied solvent solution is transferred to the recovery tank extremely efficiently. Also, since valve v7 is closed, even if there is gas that does not liquefy, it will not be released into the atmosphere.
The clean solvent liquid in the recovery tank 6a is transferred to the clean liquid tank 6.
When the remaining amount of b decreases, it is transferred to the fresh liquid tank via valve V7 and a vacuum pump.

乾燥を行う（第四工程）。Then, when the steam cleaning is completed, the valve Vl,
By closing valve V3, opening valve V2, and operating the vacuum pump, the cleaning tank 2 is brought into a vacuum state and the workpiece 1 is dried (fourth step).
上記第一一〜第四工程は、ワークｌの汚れ具合に応じて
適宜数回繰返されることもあり、繰返すごとに汚れの除
去効果は向上する。The above-mentioned eleventh to fourth steps may be repeated several times depending on the degree of contamination of the workpiece 1, and the dirt removal effect improves each time it is repeated.
