The present invention provides a draining system to supply and retrieve solvents to a vacuum cleaning dryer and a storage tank, characterized by comprising; a dryer (10) to perform washing and drying of products in a vacuum condition at least inside; and a solvent tank (20) to supply and retrieve for storage of a washing solution and a rinse solution with installation adjacent to the dryer (10) of a washing tank (22) and a rinse tank (23) divided by a partition wall (25); and a means of drainage branched out for connection between the dryer (10) and the washing tank(22)/rinse tank(23) to supply or retrieve the washing solution and the rinse solution to the dryer (10) and the washing tank (22)/ rinse tank (23) by pressure difference of a vacuum pump (30). Accordingly, the present invention has effects that; installation time and management is easy for an excellent applicability to fields due to integrated installation on the ground of the dryer to wash and dry contaminants off of product surfaces, and efficiency as well as safety are outstanding as not only supply of solvents to a vacuum chamber (dryer) but also retrieval to the storage tank are performed smoothly in a stable manner and productivity can be improved as a detergency power of oils is outstanding for an improved cleaning power. |
