2. Description of the Related Art Conventionally, as an industrial cleaning device for cleaning an object to be cleaned such as a machine part, usually, the object to be cleaned is stored in a container of a cleaning chamber in which a cleaning liquid composed of trichloroethane is stored, and the strength of trichloroethane A device configured to perform cleaning by various cleaning functions has been widely put into practical use. However, in recent years, it has been found that trichloroethane in the atmosphere is a cause of ozone layer depletion, and in order to protect the ozone layer, the use of trichloroethane will be banned in the near future, and cleaning liquids other than trichloroethane will be used. The need for cleaning things has arisen.

Therefore, as a cleaning liquid other than trichloroethane, for example, an industrial cleaning device for cleaning an object to be cleaned with an alkaline cleaning liquid has been proposed. In this industrial cleaning device, a cleaning chamber and a cleaning liquid storage chamber are arranged adjacent to each other. Cleaning the object to be cleaned contained in the container in the cleaning chamber, storing the cleaning liquid overflowing from the cleaning chamber and the oily floating components generated by the cleaning and floating in the upper layer of the cleaning liquid in the cleaning liquid storage chamber, and storing the cleaning liquid storage The cleaning liquid in the chamber is introduced into the cleaning chamber, and the cleaning liquid is circulated between the cleaning chamber and the cleaning liquid storage chamber to clean the object to be cleaned with the cleaning liquid.

[0004]

However, in general, between the cleaning chamber and the cleaning liquid storage chamber, the cleaning liquid overflowing in the cleaning chamber and an oily floating component generated by the cleaning and floating in the upper layer of the cleaning liquid are stored in the cleaning liquid storage chamber. Since there is a head for receiving the oil, the overflowing oily floating components fall abruptly and deeply settle in the cleaning liquid stored in the cleaning liquid storage chamber. The oily floating components that have deeply settled in the cleaning liquid are mixed as fine oil particles in the cleaning liquid in a state where some of them are emulsified, so the cleaning liquid containing the oily floating components and having weaker cleaning power becomes the cleaning liquid storage chamber. Since it is introduced into the cleaning chamber from the pump through the pump, there is a problem that the cleaning power of the cleaning target for the cleaning target in the cleaning chamber becomes weak. Moreover, when the cleaning liquid in the cleaning liquid storage chamber is sucked by the pump, the oily floating components floating in the upper layer of the cleaning liquid settle into the cleaning liquid, and the cleaning liquid is further deteriorated and the cleaning power is weakened. .

Although it is necessary to suck the oily floating components floating in the upper part of the cleaning liquid in the cleaning liquid storage chamber with the cleaning liquid in the upper layer by a pump and remove the oily floating components through the floating oil separating device, Since the liquid surface area is large, the oily floating components float in a wide range in the upper portion of the cleaning liquid, which causes a problem that the recovery efficiency for collecting the oily floating components is reduced. An object of the present invention is to provide an industrial cleaning device capable of maintaining a high cleaning power by increasing the recovery efficiency for recovering a large amount of oily floating components floating in the upper part of the cleaning liquid in the cleaning chamber and the cleaning liquid storage chamber. Is.
