[0002] Oil sludge is the abbreviation of oily sludge, which is the oily solid waste generated during oil extraction, transportation, refining and oily wastewater treatment. The existing treatment methods are generally incineration, biological treatment, thermal washing, solvent extraction, chemical demulsification, solid-liquid separation, etc. These methods cannot effectively recover the oil and gas components contained therein, which not only causes a waste of oil and gas resources, but also produces more difficult-to-treat waste. Therefore, it is difficult to be better promoted and applied. Treating oil sludge by high-temperature cracking is a good choice, but these loose oil sludges need to be uniformly and continuously fed to achieve subsequent continuous cracking.

[0003] When testing the oil sludge, it is necessary to dry the oil sludge. Traditional drying devices dry the oil sludge during the stirring process. However, even if the oil sludge is continuously stirred, the oil sludge will still accumulate together, resulting in low drying efficiency. Utility Model Content

[0004] In view of the problem that traditional drying devices dry the oil sludge during the stirring process, but the oil sludge will still pile up even if it is continuously stirred, resulting in low drying efficiency, the utility model provides a drying device for treating oil sludge.

[0010] Preferably, the drying assembly comprises a hot air blower and an air duct, the hot air blower is fixedly arranged on the outer side wall of the drying box, the air outlet of the hot air blower is connected to the air duct, and the end of the air duct away from the hot air blower is connected to the drying box.

[0011] Preferably, four legs are provided at the bottom end of the drying box.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The motor drives the stirring shaft and multiple stirring blades to rotate. The stirring shaft drives the feeding shaft to rotate through two synchronous wheels and a synchronous belt, and then drives the feeding spiral piece to rotate, so that the sludge in the feeding barrel is transported to both sides, thereby maintaining a uniform feeding speed and preventing excessive accumulation of sludge.

[0014] 2.
