[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] When refining petroleum, distillation is often used to separate different components, allowing them to evaporate sequentially at specific boiling points. Therefore, a distillation separation unit is required for refining crude oil. During the refining process, petroleum is often distilled, and after distillation, a large amount of petroleum residue often remains inside the distillation unit. Some of this residue adheres to the oil and is difficult to discharge directly, making it very troublesome to clean the distillation separation unit.

[0004] While existing crude oil distillation and separation units can scrape off adhered petroleum residue, the scraping area is limited, resulting in low cleaning efficiency. This leaves adhered petroleum residue, which can affect the subsequent operation of the unit if not promptly removed. Excessive scraping mechanisms can also impair distillation performance. Furthermore, after scraping off the residue, existing units must manually remove it from the unit, which is time-consuming and labor-intensive, increasing the workload and resulting in low residue collection efficiency.

[0029] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0030] The present invention is described in detail below with reference to the accompanying drawings. The present embodiment discloses a crude oil distillation separation device for petroleum refining. Figure 1 As shown, it includes a base 1, a distillation body 2 is set on the top of the base 1, a servo motor 3 is set on the upper end of the distillation body 2, the output end of the servo motor 3 passes through the distillation body 2 and is connected to the rotating rod 4, an adjusting rod 5 is set inside the rotating rod 4, and the bottom of the adjusting rod 5 is connected to the knob 6; before using the device, the knob 6 can be manually rotated first, and after rotation, the scraper 10 will be adjusted to a suitable angle. After adjustment, the device can be started.

[0031] like Figure 3 and Figure 4 As shown, a number of driving gears 7 are spaced apart and sleeved on the adjusting rod 5. The driving gears 7 are fixedly connected to the adjusting rod 5. Driven gears 8 are provided at both ends of the driving gear 7 and mesh with the driven gears 8. The ends of the driven gears 8 are fixedly connected to the connecting rod 9, which passes through the rotating rod 4 and the ends of the connecting rod 9 are fixedly connected to the scraper 10. Both the driving gears 7 and the driven gears 8 are bevel gears.

[0032] The adjusting rod 5 is rotatably connected to the rotating rod 4. The adjusting rod 5 is driven to rotate by the knob 6. The rotation of the adjusting rod 5 drives the driving gear 7, which in turn drives the driven gears 8 at both ends, thereby rotating the connecting rod 9 and finally rotating the scraper 10, thereby adjusting the angle of the scraper 10. After the scraper 10 rotates to a certain angle, the servo motor 3 is activated, which drives the rotating rod 4 to rotate. The adjusting rod 5 is limited by the limit block 18 and the circular slot 19, so that the rotation of the rotating rod 4 only drives the connecting rod 9, thereby rotating the scraper 10 with the center position of the fractionating body 2 as the origin, thereby scraping the petroleum residue on the inner wall of the fractionating body 2. After scraping is completed, the angle of the scraper 10 can be adjusted to increase or decrease the scraping area, achieving scraping at multiple angles and avoiding missing petroleum residue. Scraping from multiple angles is also convenient for processing tightly bonded petroleum residue, gradually loosening the tightly bonded petroleum residue and then scraping it off, which has strong applicability.

[0033] like Figure 5 As shown, the bottom of the fractionator body 2 is provided with an arcuate slot 11. The inner walls of both ends of the arcuate slot 11 are provided with limit slots 12, and the inner wall of the lower end of the arcuate slot 11 is provided with a retaining slot 24. A baffle 14 and a collection frame 16 are disposed within the arcuate slot 11. The collection frame 16 is fixedly connected to the inner side of the baffle 14 and is located within the fractionator body 2. The collection frame 16 is used to collect the petroleum residue scraped off by the scraper 10. The petroleum residue scraped off by the scraper 10 falls into the collection frame 16. After a certain amount of petroleum residue has been collected, the baffle 14 is pulled to remove the collection frame 16. After the collected petroleum residue has been poured out, the collection frame 16 is reinserted into the arcuate slot 11 to continue collecting petroleum residue.

[0034] The baffle 14 is provided with limit sliders 13 at both ends, which are located in the limit slots 12. A clamping block 15 is provided at the lower end of the baffle 14, which is located in the clamping slot 24. The limit sliders 13 and the clamping block 15 are fixedly connected to the baffle 14. When the baffle 14 slides to the bottom, the clamping block 15 engages in the clamping slot 24, which holds the block 15 in place. The clamping block 15 also limits the position of the baffle 14, preventing it from shifting.

[0035] like Figure 2 As shown, an adjustment slider 17 is provided on one side of the adjustment rod 5. One end of the adjustment slider 17 is fixedly connected to the adjustment rod 5, and the other end of the adjustment slider 17 is located outside the rotating rod 4. A plurality of stoppers 18 are provided at intervals inside the adjustment slider 17 and fixedly connected to the adjustment slider 17. The surface of the lower end of the rotating rod 4 has circular slots 19, which are arranged at intervals. The stoppers 18 engage with the circular slots 19.

[0036] When the adjusting rod 5 is rotated to a certain angle, the limit block 18 will be stuck in the slot on the rotating surface, so that the limit block 18 and the adjusting slider 17 are fixed; a circular slot 19 is provided at the bottom of the surface of the rotating rod 4, and the outer surface of the limit block 18 is stuck in the inside of the circular slot 19. Through the setting of the circular slot 19, when the limit block 18 is stuck in the inside of the circular slot 19, the circular slot 19 limits the limit block 18 to prevent the position of the limit block 18 from shifting.

[0037] A connecting pipe 20 is fixedly connected to one side of the surface of the fractionating body 2, and a heater 21 is fixedly connected to one end of the connecting pipe 20. A connecting groove 25 is provided at the bottom of one side of the fractionating body 2, and a controller 22 is fixedly connected to the interior of the connecting groove 25. The controller 22 is electrically connected to the heater 21 and the servo motor 3. The controller 22 controls the heater 20 to heat for distillation; when the angle of the scraper 10 needs to be adjusted, the controller 22 controls the servo motor 3 to drive the adjusting rod 5 to rotate, and finally transmits power through the driving gear 8, the driven gear 8, and the connecting rod 9, so that the scraper 10 rotates, thereby achieving the angle adjustment of the scraper 10.

[0038] A mounting groove 26 is provided on one side of the fractionation body 2 away from the connecting pipe 20. An oil outlet pipe 23 is fixedly connected to the interior of the mounting groove 26, and a plurality of oil outlet pipes 23 are arranged at intervals.

[0039] The working steps of the distillation separation device are as follows:

[0040] The first step: by turning the knob 6, the adjusting rod 5 is driven to rotate, and the adjusting rod 5 is driven to rotate the driving gear 7, and the driving gear 7 is driven to rotate the driven gear 8, and the driven gear 8 is driven to rotate the connecting rod 9, thereby driving the scraper 10 to adjust its own angle. After adjustment, the servo motor 3 is started by the external power supply of the device, driving the rotating rod 4 to rotate, thereby driving the scraper 10 to scrape the oil on the inner wall of the device. The operator can pull the baffle 14 outward, at this time, the collecting frame 16 will be pulled out, and the collecting frame 16 will collect the oil residue. After the oil residue is inverted, the baffle 14 is pushed to return the baffle 14 and the collecting frame 16 to their original positions. The collection frame 16 can be driven to slide up and down by the cooperation of the limiting slide 12 and the limiting slider 13; a reserved slide with the same height as the baffle 14 is left between the top of the limiting slide 12 and the fractionating body 2, so that no resistance is generated to the baffle, and the purpose of sliding up and down is to realize the opening and closing of the baffle 14;

[0041] Step 2: When the adjusting rod 5 is rotated to a certain angle, the limit block 18 is inserted into the slot on the rotating surface, so that the limit block 18 and the adjusting slider 17 are fixed. When the limit block 18 is inserted into the circular slot 19, the circular slot 19 limits the limit block 18 to prevent the position of the limit block 18 from shifting. The heater 21 and the connecting pipe 20 are used in conjunction with each other to heat and distill the interior of the fractionating body 2.

[0042] Step 3: The controller 22 is electrically connected to the servo motor 3. The controller 22 model is OHR-PR10. The oil outlet pipe 23 is fixed by the setting of the mounting groove 26. The crude oil can be discharged through the setting of the oil outlet pipe 23.

[0043] Although the above description of the specific implementation methods of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
