Claims

[Scope of Claim for Utility Model Registration] (1) A cleaning tank that can be sealed while storing an object to be cleaned, a supply means that can freely feed an organic solvent for cleaning into the cleaning tank, and a supply means that is present in the cleaning tank. It is built into a washer that uses an organic solvent, which consists of a vacuum pump that discharges gas that is , a solvent regeneration and recovery device that recovers the organic solvent vapor present in this gas, which includes a storage section for storing the liquid organic solvent, and a storage section provided at the bottom of this storage section, which is located inside the storage section. A heater for heating and evaporating the liquid organic solvent, a cooler installed in a closed space above the reservoir to condense and liquefy the organic solvent, and a receiver for receiving the organic solvent condensed by the cooler. a dehumidifier whose interior is filled with a desiccant that can be reused and which removes moisture from the air passing through the interior from the suction port toward the discharge port; and a suction pipe with one end open to the sealed space; a first check valve that is provided in the middle of the suction pipe and allows gas to pass only toward the closed space; one end of the valve is connected to the other end of the suction pipe; the other end is connected to the outlet of the dehumidifier;
A first pipe with an on-off valve in the middle, a hot air feed pipe with a heater for heating the air in the middle, one end connected to the downstream end of this hot air feed pipe, and the other a second pipe whose ends are respectively connected to the hot air inlet provided at the lower end of the dehumidifier and another on-off valve provided in the middle; and a gas containing organic solvent vapor discharged from the sealed space. cool down,
A secondary cooler that condenses the organic solvent vapor in the gas and recovers the organic solvent, and a pipe that connects the secondary cooler installation part with the outside space is provided in the middle of the pipe.
A regeneration and recovery device for a washer solvent using an organic solvent, comprising a second check valve that allows gas to pass only from the closed space to the outside space. (2) A cleaning tank that can be sealed while storing the object to be cleaned, a supply means that can freely feed an organic solvent for cleaning into the cleaning tank, and a vacuum pump that discharges gas existing in the cleaning tank. It is installed in a cleaning device that uses organic solvents, and the used organic solvent discharged from the cleaning tank is sent in to regenerate it, and the gas discharged from the vacuum pump is sent in to remove the organic substances present in this gas.
