Still further, the impurity box 22 is fan-shaped, the inner walls of the impurity box 22 adjacent to the collection port 23 are both inclined surfaces inclined toward the collection port 23, the top surface of the impurity box 22 and the top surface of the brush 25 are both in sliding contact with the bottom surface of the filter plate a17, the brush 25 can generate scraping effect on the filter plate a17, thereby, the foreign matter can be stirred out from the holes of the filter sheet a17, and then under the sliding contact relationship between the top surface of the foreign matter box 22 and the bottom surface of the filter sheet a17, the foreign substances which are stirred but not embedded in the filter plate are scraped into the inner wall of the foreign substance case 22 by the top surface of the foreign substance case 22, and since the mass of the foreign substance case is greater than that of oil, under the high-speed rotation of the foreign substance case 22, it is closely adhered to the inner wall of the impurity box 22 on the other side of the collecting port 23, and when the rotation is stopped, the impurities in the impurity box 22 fall on the inner bottom surface of the impurity box 22, and the oil doped with the impurities flows back to the centrifugal chamber 16 by the filtering effect of the filter sheet B24.

It is worth introducing that, the sealing plate 27 is a T-shaped structure, the inner side end of the sealing plate 27 is an arc surface structure with the same radian as the radian of the inner wall of the centrifugal cavity 16, the inner side end of the sealing plate 27 is in inserting fit with the cleaning port 26, the screw 29 is in threaded connection with the screw hole 30, the rotating shaft 31 is in rotating connection with the fixing seat 10 and the outer barrel 2 which are positioned on the lower side, the top surface of the motor 32 is fixedly connected with the bottom surface of the outer barrel 2, the motor 32 is connected with an external power supply through a wire, and a worker can clean the impurities collected in the impurity box 22 through the cleaning port 26 by only unscrewing the screw 29 and pulling out the sealing plate 27, so that the problem that the impurities block the filter plate a17 is effectively avoided, the convenience of the worker for cleaning the device is also improved, and the cleaning device is achieved by one stroke.

The working principle is as follows: when a worker uses the device to carry out petroleum centrifugal processing, the movable door 8 can be opened firstly, then the end part of the conveying pipe 6 is inserted into the feeding pipe 18, because the structure of the conveying pipe 6 is the same as that of the opening end of the feeding pipe 18, the telescopic rod 19 and the compression spring can not cause obstruction to the conveying pipe 6, and the baffle 20 can be extruded out of the opening end at the lower side of the feeding pipe 18 under the extrusion effect of the conveying pipe 6 on the top surface of the baffle 20, at the moment, petroleum to be centrifugally processed outside can be extracted by the oil pump 3 and poured into the inner cylinder 12, the petroleum can flow out through the through grooves at the two sides of the conveying pipe 6, the feeding pipe 18 can be fully sealed by the structure, so that the petroleum containing impurities or the impurities can not penetrate out of the feeding pipe 18 no matter whether the centrifugal force is gradually increased or gradually reduced in the starting and ending processes of the rotation of the inner cylinder 12, and the fine degree of centrifugal separation of the petroleum and the impurity separation of the device is enhanced, the purity of the petroleum processed by the device is improved, after the petroleum is filled into the centrifugal cavity 16 by workers, the inner cylinder 12 can be driven to rotate by the motor 32, because the rear wall of the centrifugal cavity 16 is of an inclined surface structure, the rotating curve of the centrifugal cavity 16 is of an inverted circular truncated cone structure coaxial with the inner cylinder 12 in the rotating process of the inner cylinder 12, so that the petroleum can better move upwards along with the centrifugal force and achieve the effect of separating the petroleum and impurities under the filtering effect of the filtering plate A17 by utilizing the inclined surface to exert the oblique upward guiding effect while the inner cylinder 12 generates the centrifugal force on the petroleum in the rotating process, the practicability is strong, two impurity boxes 22 are fixedly arranged on two sides of the inner wall of the inner cylinder 12 in a central symmetrical structure, the front end of the top surface of the inner cylinder 12 is also embedded with a brush 25, and in the rotating process of the inner cylinder 12, the brush 25 can generate the scraping effect on the filtering plate A17, therefore, impurities can be stirred to avoid being embedded into the holes of the filter plate A17, then under the sliding contact relationship between the top surface of the impurity box 22 and the bottom surface of the filter plate A17, the part of impurities stirred but not embedded into the filter plate can be scraped into the inner wall of the impurity box 22 by the top surface of the impurity box 22, because the mass of the impurities is greater than that of oil, under the high-speed rotation of the impurity box 22, the impurities can be tightly attached to the inner wall of the impurity box 22 on the other side relative to the collecting port 23, when the rotation stops, the impurities in the impurity box 22 can fall on the inner bottom surface of the impurity box 22, the oil doped in the impurities can flow back to the centrifugal cavity 16 under the filtering effect of the filter plate B24, then a worker only needs to screw down the screw 29 to pull out the sealing plate 27 to clean the impurities collected in the impurity box 22 through the cleaning port 26, the problem that the impurities block the filter plate A17 can be effectively avoided, and the convenience of the worker for cleaning the device is improved, one thing can be done in two ways, and finally the oil thrown out of the inner barrel 12 under the action of centrifugal force can be downwardly concentrated to the lower part of the inner side of the outer barrel 2 along the inverted round platform structure on the inner wall of the outer barrel 2, and workers only need to take a proper container to collect the oil after centrifugal processing at the discharge pipe 9.
