Description

Technical Field

[0001] The utility model relates to the technical field of equipment for treating contaminated oily sludge, in particular to a device for treating oily sludge with reduced volume. Background Art

[0002] Oily sludge is a common waste generated during industrial production, typically containing various oils, sediment particles, and other components. It is a major pollutant in the petroleum and petrochemical industries. Technologies for harmlessly rendering, reducing, and repurposing oily sludge will become an inevitable trend in the development of oily sludge treatment technology. Oily sludge reduction refers to the fact that most waste is loose and bulky, increasing transportation costs and occupying large landfills. Therefore, solid waste is compressed, liquid waste is concentrated, or the waste is harmlessly incinerated to reduce its volume to facilitate transportation and landfilling. In the existing technology, most of the oily sludge reduction treatment equipment uses an extrusion method. For example, publication number CN216801064U is titled "An Oily Sludge Reduction Equipment." The working principle of this device is to pour the oily sludge into the reduction box through a feed hopper, and then use a transmission mechanism to make the extrusion plate move up and down while performing a small angle reciprocating rotation to compress and grind the oily sludge, reducing the volume of the oily sludge, thereby achieving the effect of reducing the amount of oily sludge. However, such extrusion treatment has low efficiency. In addition, the oil contained in the oily sludge cannot be separated, resulting in a waste of resources. Summary of the Invention
