Description

Technical Field

[0001] The utility model belongs to the technical field of oil residue filtering and separating devices, and in particular relates to an oil residue filtering and separating device for an oil scooping machine. Background Art

[0002] In industrial processes, a large amount of oily wastewater or waste oil is often generated. Filtration and separation of oil residue in oil-water mixture is a key operation. Oil residue refers to solid particles suspended or mixed in liquid. Its presence may cause equipment blockage, fluid pollution and equipment performance degradation. At present, oil residue in oil-water mixture is usually separated by oil skimmer. In a centrifugal oil skimmer, the oil-water mixture is injected into a centrifugal cylinder, and the centrifugal force generated by the high-speed rotation of the centrifugal cylinder causes the oil residue with higher density to be thrown onto the wall of the centrifugal cylinder to form a layer or condense at the bottom, while the clean oil-water mixture flows out through the middle of the screen to achieve filtration and separation of the oil residue. However, in the process of filtration and separation of the oil residue, the oil residue condensed on the inner wall of the centrifugal cylinder is not convenient to be scraped and cleaned, which affects the filtration and separation effect of the centrifugal cylinder on the oil residue. It is difficult to reduce the noise generated by the device during the separation process. Utility Model Content

[0033] During operation, the oil-water mixture is poured into the pretreatment box 301, and the mixture is temporarily stored in the pretreatment box 301 after being filtered through the filter plate 303. When the mixture needs to be pumped into the centrifugal cylinder 107, the oil pump 202 is turned on to inject the preliminarily filtered mixture in the pretreatment box 301 into the centrifugal cylinder 107.

[0037] Through the above steps, when in use, the oil-water mixture is placed in the pretreatment component 3, and the pretreatment component 3 is used to preliminarily filter the mixed liquid to prevent large particles of impurities from clogging the oil extraction component 2.

When it is necessary to remove impurities adhered to the inner wall of the centrifugal structure, the scraping component 5 is turned on to remove the impurities adhered to the centrifugal structure. When performing centrifugal operation, the sound insulation component 6 is placed on the scraping component 5 to reduce the noise emission, which solves the problem that in the process of filtering and separating the oil residue, the oil residue condensed on the inner wall of the centrifugal cylinder is inconvenient to be scraped and cleaned, affecting the filtering and separation effect of the centrifugal cylinder on the oil residue, and it is difficult to reduce the noise generated by the device during the separation process.

[0038] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
