Joint harmless treatment apparatus of waste rolling oil and oil-bearing waste diatomite

The invention discloses a joint harmless treatment apparatus of waste rolling oil and oil-bearing waste diatomite, comprising a feeding system, a joint vaporizing separation system, and a recycled oilcollection system. Boiling point reduction by vacuumizing cooperates with the thermal fractionation principle; extracted oil is recycled after condensation; cracking and carbonizing of the oil duringheat are effectively prevented; no waste smoke or vapor is produced during the whole treatment process so that the apparatus has the advantages of simple structure and good economy and environmentalfriendliness. The apparatus herein employs inner and outer cylindrical cavity structure, featuring uniform heating and high production efficiency. The recycled oil collection system can monitor oil-vapor temperature in a pipeline in real time; the type of oil is automatically judged according to oil-vapor temperature data; the oil is automatically recycled to a corresponding collection device; inaddition, by adjusting rotat
