Oil-based drilling cutting oil-liquid separation treatment device

An oil-based drilling cutting oil-liquid separation treatment device comprises a device shell, a driving motor, a rotating shaft and hammer milling blades, the device shell is provided with a feeding port and an exhaust pipeline, the bottom face of the device shell is provided with a discharging port, the driving motor is arranged outside the device shell, the rotating shaft is horizontally arranged inside the device shell, and the hammer milling blades are arranged on the driving motor. The rotating shaft is arranged in the device shell and connected with the output end of the driving motor, multiple sets of hammer milling blades are arranged on the rotating shaft at intervals in a surrounding mode, and a steam inlet is further formed in the device shell; a negative pressure condition and steam are introduced into a hammer mill thermal desorption system, the oil vaporization temperature is reduced, the solid-liquid separation efficiency is improved, meanwhile, oil cracking caused by too high temperature is a
