Reference numeral 1 is a cleaning tank, and the cleaning tank 1 is a drum type case containing a rotatable drum for accommodating normal parts. Has been done. Further, the cleaning booster 1 is equipped with a steam jacket 2 for heating the washing liquid, and water or an aqueous washing liquid is supplied through the conduit 3 and discharged through the conduit 4. Reference numeral 5 indicates a container for accommodating a cleaning active substance and the like to be put into an aqueous cleaning liquid. At the start of cleaning, after the dirty parts are filled in the cleaning tank 1, the solvent is injected into the cleaning tank 1 from the solvent storage tank 6 by the pump 7 via the conduit 8. While cleaning the parts with the solvent, the cleaning liquid is circulated by the pump 7 through the conduits 9 and 8 forming a closed circulation path together with the cleaning tank 1, in order to remove insoluble dirt by operating a suitable valve. The filter 10 can also be connected to the line 8. When this washing process is completed, the solvent washing liquid is sent to the storage tank 6 or, if the dirt is large, to the distillation container 12 via the pump 7 and the conduit 11, and the components are centrifugally deliquified for a short time.
After removing the solvent in this way, the washing tank 1 can be filled with the washing solution 1 by means of the conduit 3, in which case the washing active substance can be added from the container 5. Next, wet cleaning is performed in the cleaning tank 1, and at this time, the cleaning tank 1 is cleaned by the steam jacket 2.

を介して溶媒貯留タンク６と連通する。The remainder of the solvent still present in the product from the previous solvent treatment, here "when using tetrachloroethylene" forms an azeotrope with the abovementioned aqueous wash. Since the temperature of the washing liquid rises above the azeotropic point of this mixture, the vapor rising from the washing liquid reaches the condenser 14 via the conduit 13 together with the solvent content contained therein. Preferably, in order to accelerate evaporation, a vacuum pump 21 is connected to the cleaning tank 1, and the vapor sucked by this pump is pushed into the condenser 14 by the conduit 13a. When the pump 21 operates, the conduit 13 is shut off. In the example shown here, it is also possible to circulate the heated wash liquor via the conduits 9 and 8 by means of the pump 7 in order to collect the residual solvent remaining in the wash liquor. During this cleaning process, all conduits connected to the cleaning tank 1 are of course shut off, except for these conduits 8, 9 and 13 or 13a. The condensate recovered in condenser 14 is sent to a water separator 15 where it is separated into two phases, water and solvent, and water is discharged via conduit 16. Further, the solvent outlet of the water separator 15 is connected to the solvent storage tank 6 via a flow meter 17 and a conduit 18 for displaying the amount of passing solvent per unit time. When the flow meter 17 displays the value of 0 or the minimum allowable value,
The washing process can be interrupted immediately. The washing liquid is then drained by the conduit 4. After a brief spin-drying, the washings can be taken out of the washing tank 1 without danger, ie without any residual undesired solvent, or can be pre-rinsed again as usual with an aqueous washing solution. A condenser 19 is also connected to the distillation vessel 12, the condensate outlet of which is connected to a water separator 20, while the water separator 20 communicates with the solvent storage tank 6 via the solvent outlet.

る。Next, the operation of the embodiment constructed as described above will be explained. A machined part soiled with water-soluble processing oil or the like is housed in the cleaning basket 38, and the rotating disk 3 in the cleaning tank 1 is stored.
It is fixed or suspended on a suspension rod 37 which is vertically installed at 6. Next, an aqueous alkaline cleaning solution is sprayed from the alkaline cleaning solution storage tank 31 by the pump 7 through the conduit 9, the strainer 35, and the conduit 8 toward a cleaning basket from a plurality of nozzles (not shown) provided in the upper part of the cleaning tank 1, When the liquid level of the cleaning liquid accumulated in the cleaning tank 1 reaches the specified height, a circulation circuit for returning from the cleaning tank 1 to the pump 7 is formed and circulates. The washing liquid is sprayed with the cleaning liquid from the upper part and is repeatedly immersed in the cleaning liquid accumulated below to remove water-soluble stains. After a certain period of time, the alkaline cleaning liquid is returned to the alkaline cleaning liquid storage tank 31 by its own weight. Then, the organic solvent is transferred from the organic solvent storage tank 6 by the pump 7 to the conduit 9 and the strainer 3.
5, through the conduit 8 and supplied to the cleaning tank 1 in the same manner as described above, the cleaning tank 1, the cleaning basket 38 and the objects to be cleaned therein, the conduits 8 and 9.
The alkaline cleaning liquid, the residue of dirt, the oil content, and the cleaning agent remaining in 1 are roughly cleaned, and the used solvent is drained to the distiller 12 as it is. It is known that, at the stage when this step is completed, slightly dispersed water remains on the surface of the object to be washed, and if it is not removed quickly, it will rust over time.

A circulation circuit for air returning to the cleaning tank 1 through the above is formed, and the heating jacket 2 is operated to increase the temperature of the air in the cleaning tank 1 to 6
The object to be washed is dried by keeping the temperature at about 0 ° C. and circulating air for about 3 minutes. The solvent contained in the air is condensed by the air killer 33 and sent to the water separator 20, and the air whose temperature has been lowered by the air cooler 33 is reheated by the air heater 34. After the article to be washed is dried, an organic solvent is supplied to the washing tank 1 and circulated in the same manner as in the rough washing to perform the main washing. The oil and oil-soluble stains adhering to the object to be washed are removed by being treated for a certain period of time while repeatedly spraying the solvent from above and soaking in the solvent accumulated below, and then removing the organic solvent. The liquid is discharged to the distiller 12 via the strainer 35, and the whole process is completed after the drying process. After the rough cleaning, the drying may be omitted and the process may directly proceed to the main cleaning step. The organic solvent sent to the distiller 12 is condensed and collected by the condenser 19, the water is removed by the water separator 20, and the organic solvent storage tank 6 is returned. The aqueous alkaline cleaning solution is repeatedly used, and when the contamination reaches the limit, it is drained to the distiller.
