Description

Technical Field

[0001] This utility model relates to the field of waste lubricating oil treatment technology, specifically a separation device for removing impurities from waste lubricating oil. Background Technology

[0002] In the recycling process of waste lubricating oil, it is necessary to separate the impurities in order to recover relatively pure lubricating oil.

[0003] Chinese patent CN218248817U discloses a filtration and separation device for removing impurities from lubricating oil. The device includes a filter cylinder with a top cover movably fitted to its top. Bolts are threaded onto the outer surface of the top cover. An inner rotating ring is rotatably connected inside the top cover. A feed pipe is welded to one end face of the inner rotating ring. A discharge pipe is welded to the outer bottom end of the filter cylinder. Caps are threaded onto the ends of both the feed and discharge pipes. An outer support is welded to the other end face of the inner rotating ring. A hydraulic cylinder is welded to the top of the outer support. A hydraulic rod is welded to the output end of the hydraulic cylinder. This patent allows lubricating oil to be poured into the filter cylinder through the feed pipe for filtration. The extension and retraction of the hydraulic rod ensures uniform mixing of the lubricating oil, preventing it from settling to the bottom.

[0004] In the above technical solution, when filtering waste lubricating oil using filter holes, as the system continues to operate, impurities such as metal shavings, gum deposits, and carbon particles in the lubricating oil will continuously accumulate in the filter holes, clogging them and reducing the effective filtration area. This results in a decrease in the filtration efficiency of the device and delays the work process.

[0005] Based on this, the present invention proposes a separation device for removing impurities from waste lubricating oil. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes a separation device for removing impurities from waste lubricating oil. The device uses a multi-stage electric telescopic rod to move a rotating plate upwards, and a motor and rotating column to rotate the plate. As the plate moves upwards, it rotates, causing the brush to move upwards and rotate, cleaning the inner wall of the filter screen and preventing impurities from clogging it and affecting filtration efficiency. Simultaneously, the rotating plate squeezes the lubricating oil, accelerating the filtration of waste lubricating oil.

[0007] The technical solution to achieve the purpose of this utility model is: a separation device for removing impurities from waste lubricating oil, including a shell, two discharge pipes fixedly connected to the shell, a top cover movably connected to the shell, a feed pipe fixedly connected to the top cover, a filter screen fixedly connected to the top cover, and further comprising;

[0008] A rotating column is rotatably connected inside the outer casing. A rotating plate is slidably connected to the rotating column. Multiple brushes are fixedly connected to the rotating plate. Two multi-stage electric telescopic rods are fixedly connected to the top cover. Fixed rings are fixedly connected to the output shafts of the two multi-stage electric telescopic rods. The fixed rings are rotatably connected to the rotating plate.

[0009] Preferably, the outer casing is provided with an observation window, and a sealing ring is fixedly connected inside the outer casing.

[0010] Preferably, the feed pipe and the two discharge pipes are each threaded with three sealing caps.

[0011] Preferably, a motor is fixedly connected to the outer casing, and a rotating column is fixedly connected to the output shaft of the motor, with two sliding grooves formed on the rotating column.

[0012] Preferably, the rotating plate has a limiting groove that is adapted to the rotating column, and the top cover has four through grooves.

[0013] Preferably, four rotating columns are rotatably connected to the outer shell, and multiple limiting blocks are fixedly connected to each of the four rotating columns.

[0014] Compared with existing technologies, the significant advantages of this invention are:

[0015] Firstly, in this utility model, the rotating plate is driven to move upward by a multi-stage electric telescopic rod, and the rotating plate is driven to rotate by a motor and a rotating column, so that the rotating plate rotates while moving upward, driving the brush to move upward and rotate, cleaning the inner wall of the filter screen, avoiding impurities from clogging the filter screen and affecting the filtration efficiency. At the same time, the rotating plate squeezes the lubricating oil, accelerating the filtration of waste lubricating oil.

[0016] Secondly, in this utility model, when it is necessary to clean the filter screen, the rotating column can be rotated to drive the limiting block to rotate, so that the limiting block is directly above the through groove, and then the top cover can be moved up to remove the top cover and the filter screen from the outer shell for cleaning.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an improved separation device for removing impurities from waste lubricating oil. The technical solution of this utility model is as follows:

[0025] like Figures 1-3 As shown, a separation device for removing impurities from waste lubricating oil includes a housing 1, two discharge pipes 8 fixedly connected to the housing 1, a top cover 5 movably connected to the housing 1, a feed pipe 7 fixedly connected to the top cover 5, a filter screen 10 fixedly connected to the top cover 5, and further includes;

[0026] A rotating column 13 is rotatably connected inside the outer casing 1. A rotating plate 17 is slidably connected to the rotating column 13. Multiple brushes 19 are fixedly connected to the rotating plate 17, and the brushes 19 are arranged in a circular array with the center of the rotating plate 17 as the center. Two multi-stage electric telescopic rods 15 are fixed to the top cover 5 by bolts. A fixing ring 16 is fixed to the output shaft of the two multi-stage electric telescopic rods 15 by bolts. The fixing ring 16 is rotatably connected to the rotating plate 17. The multi-stage electric telescopic rods 15 drive the rotating plate 17 to move upward. The motor 12 and the rotating column 13 drive the rotating plate 17 to rotate, so that the rotating plate 17 rotates while moving upward, driving the brushes 19 to move upward and rotate, cleaning the inner wall of the filter screen 10, and preventing impurities from clogging the filter screen 10 and affecting the filtration efficiency.

[0027] Furthermore, such as Figures 1-3 As shown, the outer casing 1 is provided with an observation window 2, through which the filtration of waste lubricating oil inside the outer casing 1 can be observed. A sealing ring 11 is fixedly connected inside the outer casing 1, and the cross-section of the sealing ring 11 is U-shaped.

[0028] Furthermore, such as Figures 1-3As shown, three sealing caps 9 are threaded onto the feed pipe 7 and the two discharge pipes 8 respectively. During the filtration process, the sealing caps 9 can be used to block the feed pipe 7 and the discharge pipe 8.

[0029] Furthermore, such as Figure 2 and Figure 3 As shown, a motor 12 is fixed to the outer casing 1 by bolts, and a rotating column 13 is fixed to the output shaft of the motor 12 by a coupling. Two sliding grooves 14 are opened on the rotating column 13, and the two sliding grooves 14 are symmetrical about the rotating column 13.

[0030] Furthermore, such as Figures 1-3 As shown, a limiting groove 18 is provided on the rotating plate 17. The limiting groove 18 is adapted to the rotating column 13. The limiting groove 18 and the sliding groove 14 are used to limit the rotating plate 17, so that the rotating plate 17 can only slide on the rotating column 13. Four through grooves 6 are provided on the top cover 5.

[0031] Furthermore, such as Figures 1-3 As shown, four rotating columns 3 are rotatably connected to the outer shell 1, and multiple limiting blocks 4 are fixedly connected to the four rotating columns 3 respectively. Two adjacent limiting blocks 4 are symmetrical about the rotating column 3. When the limiting block 4 is directly below the through groove 6, the top cover 5 can be moved up to pull the filter screen 10 out of the outer shell 1 for cleaning.

[0032] The specific working method is as follows: Waste lubricating oil is poured into the outer casing 1 through the feed pipe 7. After entering the outer casing 1, the waste lubricating oil is located in the filter screen 10. After being filtered by the filter screen 10, it flows into the inner wall of the outer casing 1 and is discharged from the discharge pipe 8. During the filtration process, the motor 12 is started, and its output shaft drives the rotating column 13 to rotate. Since the rotating plate 17 is slidably connected to the rotating column 13, the rotating plate 17 rotates with the rotation of the rotating column 13, driving the brush 19 to rotate. At the same time, the multi-stage electric telescopic rod 15 is started, and its output shaft pulls the fixed ring 16 upward. Since the rotating plate 17 is rotatably connected to the fixed ring 16, the rotation is complete. Therefore, the rotating plate 17 moves upward along with the fixed ring 16, causing the brush 19 to move upward. This allows the brush 19 to move upward while rotating, cleaning the inner wall of the filter screen 10 and preventing impurities from clogging the filter screen 10 and affecting the filtration efficiency. At the same time, the upward movement of the rotating plate 17 squeezes the waste lubricating oil above the rotating plate 17, accelerating the filtration of the waste lubricating oil. After use, when it is necessary to clean the filter screen 10, the rotating column 3 can be rotated to drive the limiting block 4 to rotate, so that the limiting block 4 is directly above the through groove 6. Then the top cover 5 can be moved upward, and the top cover 5 and the filter screen 10 can be removed from the outer shell 1 for cleaning.

[0033] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
