Abstract: The present invention relates to intelligent oil sludge treatment apparatuses and treatment processes. The treatment apparatus includes an integrative device, an oil removal device, a separation device, a sludge collection tank, a dewatering device, a pyrolysis device, an agent tank, a deodorization tower, a crude oil tank, a light oil tank, a separator, a condenser, a desulfurization tower, a clean water tank, a sewage station, and a steam boiler, where an outlet of the integrative device is connected to an inlet of the oil removal device; the oil removal device is configured to remove crude oil from oil slurry; the oil removal machine collects the crude oil to the crude oil tank, discharges stench into the deodorization tower, and discharges the slurry into the separation device; and the separation device is configured to perform a solid-liquid separation operation.

Abstract: The present invention discloses intelligent oil sludge treatment apparatuses and treatment processes.

Abstract: A power tool comprises a housing (1), a motor (2) provided inside the housing and for outputting rotary power, and an output shaft (4) driven by the motor to rotate. The output shaft has an output end connected to a drill bit (9) and a second end provided on the other end of the output shaft; in a non-working state, the output shaft can axially move relative to the housing along the output shaft; and in a working state, the output shaft is limited in moving in a first axial direction, the first axial direction being an axial direction from the output end to the second end. The drill bit of the power tool can extend in different length according to different positions of the output shaft, so that a working mode is rapidly switched in different working conditions, especially in a small space.
