Description
Technical Field
The invention belongs to the technical field of petroleum extraction devices, and particularly relates to a petroleum extraction device for petroleum residues.
Background
Petroleum refers to a mixture of hydrocarbons in gaseous, liquid and solid states, with natural occurrence. Petroleum is classified into crude oil, natural gas liquids, natural coke oils, etc., but "petroleum" is still used as the definition of "crude oil" in a conventional manner. Petroleum is a viscous, dark brown liquid known as "industrial blood". The upper part of the crust has oil storage. The main component is a mixture of various alkanes, cycloalkanes and aromatics. Is one of the main objects of geological exploration.
In the process of oil exploitation, most of oil is extracted from the underground in a liquid manner, but because of many impurities in the oil, the extracted oil needs to be subjected to standing treatment, so that the impurities in the oil can be separated from the liquid oil, but because the oil has strong viscosity, part of the oil exists in the separated residue in the process of separating the oil from the impurities, the difficulty and the cost of extracting the oil from the residue are limited by the technology and the production cost, and therefore the oil existing in the residue is easily wasted. In order to improve the utilization rate of the petroleum in the residue, a pulverizer or an extruder is generally used for extracting the petroleum in the residue.
For example, in a chinese patent publication No. CN212375229U, a petroleum extraction device "is proposed, which comprises a device body, a residue tank and an oil storage tank are respectively installed on two sides of the top of the device body, a worker pours petroleum residues into an auger through a feed inlet, then turns on a second motor, the second motor drives the auger to rotate, the petroleum residues are pushed inward, then the worker turns on a cylinder, the cylinder drives a piston rod to extend, so that one end of the auger is raised, then petroleum flows out through a petroleum outlet, the residues are accumulated and extruded at one end of the petroleum outlet in the process that the auger pushes the residues, the auger extrudes the residues along with the increase of the residues, thereby pressing out the petroleum carried in the residues, and the petroleum flows out through the petroleum outlet under the action of gravity and pressure and is stored in the oil storage tank, so that the quality and efficiency of petroleum extraction are improved.
Although the extraction efficiency of the petroleum in the petroleum residue is improved to a certain extent, the viscosity of the petroleum is strong, the hardness and the size of the residue are different, and the petroleum is soaked in the residue, so that the petroleum residue is directly extruded out through the auger, the extrusion amount is limited, and in addition, a large amount of petroleum can be adhered to the inside of the auger in the extrusion process and is difficult to clean.
