Description

Technical Field

[0001] This utility model relates to the technical field of petroleum extraction, and in particular to a petroleum extraction device for petroleum residue. Background Technology

[0002] Petroleum is a fluid mineral buried deep underground. In the process of extracting petroleum, oil and gas flow from the reservoir to the bottom of the well and then rise from the bottom of the well to the wellhead. Petroleum plays an important role in the national economy as an energy source.

[0003] Existing petroleum extraction devices for petroleum residues, such as the petroleum extraction device for petroleum residues disclosed in utility model patent application number 202021119992.7, mainly include a device body with a residue box and an oil storage box installed on both sides of the top of the device body, respectively. In use, the operator pours the petroleum residues into the auger through the feed inlet, then turns on the second motor, which drives the auger to rotate, pushing the petroleum residues inward. Then, the operator opens the cylinder, which drives the piston rod to extend, raising one end of the auger, and then the oil flows out through the oil outlet. During the process of the auger pushing the residues, the residues are accumulated and squeezed at one end of the oil outlet. As the amount of residues increases, the auger squeezes the residues, thereby squeezing out the oils carried in the residues.

[0004] However, oil has a high viscosity, making it difficult to extract from the residue through compression. Moreover, most existing oil extraction devices do not pre-treat the oil residue, and the varying sizes of the residue greatly affect the extraction effect. Utility Model Content
