Description

Technical Field

[0001] The utility model relates to the technical field of oil sludge treatment, in particular to an oil sludge carbonization pyrolysis machine. Background Art

[0002] Oily sludge refers to oily solid waste generated during oil extraction, transportation, refining and oily wastewater treatment. The stacking or landfilling of oily sludge will not only occupy a large amount of arable land, but also cause serious pollution to the surrounding soil, water and air. Therefore, some people usually use pyrolysis equipment to treat it.

[0003] Existing sludge pyrolysis equipment is prone to form dirt on the inner wall of the device when in use. Therefore, some people usually set a scraper and use a stirring rod to drive the scraper to rotate to treat the dirt on the inner wall of the device. For example, the Chinese utility model patent with announcement number CN220393515U specifically discloses a semi-solid sludge pyrolysis device.

[0004] However, in actual use, people will find that the device heats the sludge on the inner wall of the reaction tank through a heater, but the heater is installed above the device, which makes it difficult to ensure uniform heating, greatly reducing the pyrolysis effect. And when the pyrolysis is completed and the material is discharged, it is easy to get blocked, affecting the normal discharge. Utility Model Content

During the carbonization pyrolysis process, the driving motor drives the rotating rod to rotate counterclockwise; when discharging, the driving motor drives the rotating rod to rotate clockwise. The driving of the driving motor and the heating tube is evenly controlled by an external master controller.
