The invention provides a full-automatic oil-water separation treatment device for a cooling box of a
machine tool. The device floats on the surface of cooling liquid in the cooling box of the machinetool and comprises a rack component, a lifting component, an adsorption component and a pneumatic
control system, wherein the lifting component is connected to the rack component; the adsorption component is connected to the lower portion of the lifting component and provided with
oil absorption cotton; the pneumatic
control system has dual functions of controlling the movement of the lifting component and the cleaning process of the
oil absorption cotton, and comprises a micro cylinder, a pneumatic triple piece, an
oil mist filter, a manual
control switch valve, a pneumatic control reversingvalve, a pneumatic control valve, a mechanical control
reversing valve, a vacuum generator, a vacuum chuck, a pneumatic
timer for working and a pneumatic
timer for resetting; and the pneumatic controlsystem drives and controls the lifting component and the adsorption component, and full-automatic oil-water separation treatment of the cooling box of the
machine tool is achieved on the basis of therack component. According to the invention, the pneumatic
control system is adopted, a structure is simple, using is convenient, efficiency is improved, cost is reduced, and the beneficial effects ofsaving energy, protecting the environment, being safe and reliable and being low in
failure rate are achieved.
