A kind of oil extraction device of oil residue

Abstract

The invention discloses an oil extraction device for petroleum residues in the technical field of oil extraction devices for petroleum residues. It includes a crushing box, a crushing motor is fixedly installed in the upper middle of the crushing box, a crushing shaft is fixedly connected to the bottom of the crushing motor, and the circumference of the crushing shaft is fixedly connected. The crushing claw, the crushing box is fixedly installed with the servo motor, the bottom of the crushing motor is fixedly connected to the shaft, the shaft is threaded to the threaded barrel, the lower end of the threaded barrel is fixedly connected to the bottom plate of the crushing box; the top of the bottom plate of the crushing box is fixedly connected to the annular sealing strip, and the bottom of the crushing box is provided with an annular sealing groove A plurality of supporting structures are fixedly connected around the crushing box, the right side of the crushing box is fixedly connected to the feeding structure, the left side of the crushing box is fixedly connected to the oil outlet pipe, and the left side of the crushing box is provided with an oil storage device. Fill the tank with clean water and then stir to extract oil from the oil residue by using the principle that oil is incompatible with water and its density is lower than that of water, while the density of oil residue is greater than that of water.

Description

technical field [0001] The invention relates to the technical field of oil extraction devices for petroleum residues, in particular to an oil extraction device for petroleum residues. Background technique [0002] Petroleum, one of the main objects of geological exploration, is a viscous, dark brown liquid known as the "blood of industry." There are oil reserves in parts of the upper crust. The main component is a mixture of various alkanes, naphthenes and aromatic hydrocarbons. The oil-forming mechanism of petroleum has two theories of biosedimentary oil and petrochemical oil. The former is more widely accepted. It is believed that oil is formed by organisms in ancient oceans or lakes after a long evolution. It belongs to biosedimentary oil and is non-renewable. It is believed that petroleum is generated from the carbon in the earth's crust itself, has nothing to do with biology, and is renewable. Petroleum is mainly used as fuel oil and gasoline, and is also a raw mater...

Problems solved by technology

[0003] However, after the oil is extracted, there will be some petroleum debris, and a part of the oil will be stuck in the debris. Considering the cost performance factor, most of the petroleum debris during the oil extraction process will be abandoned, which seriously reduces the oil recovery rate. However, with the rapid progress of modern industry and the rapid increase of motor vehicles, oil mines around the world have been exploited beyond the plan. Although a large number of exploitations have met the development needs, due to the non-renewable nature of oil, the less it is exploited, the lower the price of oil. gradually rises, so it is necessary to extract the oil in the residue to increase the oil recovery rate
