Description

Technical Field

[0001] This utility model relates to the field of waste oil recycling technology, and in particular to a waste white oil alkaline washing device. Background Technology

[0002] White oil, as a deeply refined mineral oil, is widely used in plastic processing lubrication, cosmetic matrix, and pharmaceutical excipients due to its chemical stability and high purity. In the plastic processing process, white oil is used as an internal lubricant in PVC calendering to reduce melt viscosity and reduce sharkskin phenomenon. However, due to high-temperature oxidation and impurity contamination, white oil turns yellow and produces a pungent odor. In order to improve resource utilization, it is usually necessary to use processes such as acid washing and distillation to recycle waste white oil.

[0003] In existing methods of alkaline washing of waste white oil, the waste white oil is usually mixed with an aqueous sodium hydroxide solution in a pretreatment pipe and washed with agitation to neutralize acidic impurities and perform preliminary decolorization. However, in actual use, the large amount of solid impurities in the waste white oil not only affects the mixing efficiency of the waste white oil and the aqueous sodium hydroxide solution, but also causes pipeline blockage as the solid impurities accumulate. Therefore, a waste white oil alkaline washing device is proposed to solve the above problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 and Figure 2An embodiment of this utility model provides a waste white oil alkaline washing device, including a tank body 2. A heating component is installed on the outer periphery of the tank body 2. From left to right, a sleeve 5, a servo motor 7, and a feed pipe 4 are fixedly connected to the top of the tank body 2. A drain pipe 12 is fixedly connected to the bottom of the tank body 2. A stirring component is installed inside the tank body 2. The heating component includes a heat insulation sleeve 1, which is fixedly connected to the outer periphery of the tank body 2. A water inlet 11 is fixedly connected to the left side of the heat insulation sleeve 1, and a water outlet 3 is fixedly connected to the right side of the heat insulation sleeve 1. The drain pipe 12 passes through the bottom of the heat insulation sleeve 1. The stirring component includes a rotating rod 9, which is fixedly connected to the output end of the servo motor 7. A stirring rod 10 is fixedly connected to the outer periphery of the rotating rod 9. First, waste white oil is fed into tank 2 through connecting pipe 6. At the same time, sodium hydroxide aqueous solution is fed into tank 2 through feed pipe 4 to mix with the waste white oil. Hot water is fed into the space between insulation jacket 1 and tank 2 through water inlet 11 to heat the waste white oil. This ensures that the waste white oil and sodium hydroxide aqueous solution are in an environment of 25℃~80℃. The drive servo motor 7 drives the rotating rod 9 to rotate, which in turn drives the stirring rod 10 to stir and mix the waste white oil and sodium hydroxide aqueous solution. This improves the mixing efficiency under the dual effects of constant temperature and stirring, thereby neutralizing acidic impurities and completing the initial decolorization.

[0034] Reference Figure 3 and Figure 4A top ring 19 is slidably connected to the middle of the sleeve 5. A filter bucket 8 is fixedly connected to the bottom of the top ring 19. A connecting pipe 6 is fixedly connected to the top of the top ring 19. An elastic component is installed in the middle of the top ring 19. A locking block 23 is slidably connected to the middle of the top ring 19. A locking groove 27 is opened in the middle of the sleeve 5. A push rod 20 is slidably connected to the middle of the sleeve 5. A push block 21 is fixedly connected to one end of the push rod 20. A push plate 22 is fixedly connected to the other end of the push rod 20. The elastic component includes a limiting block 24. The limiting block 24 is fixedly connected to the end of the locking block 23 away from the push plate 22. A sliding groove 26 is opened in the middle of the top ring 19. The limiting block 24 is slidably connected to the middle of the sliding groove 26. A strong spring 25 is installed in the middle of the sliding groove 26. An inclined surface 28 is provided on the opposite side of the locking groove 27 and the locking block 23. The push plate 22 is in contact with the locking block 23. When waste white oil is input through connecting pipe 6, it will preferentially fall into filter barrel 8. Under the action of filter barrel 8, larger solid impurities will be filtered out, thus avoiding the impact of solid impurities on mixing efficiency and preventing impurities from accumulating and clogging the pipe. After long-term filtration, by pushing push block 21, push rod 20 is driven, so that push rod 20 pushes block 23 into slide groove 26 through push plate 22, so that top ring 19 can slide out from the middle of sleeve 5, thereby removing and cleaning filter barrel 8, ensuring the filtration effect of filter barrel 8 and avoiding clogging. During installation, block 23 is aligned with slot 27 and inserted. Under the action of inclined side of inclined surface 28, block 23 will be inserted into slide groove 26 and squeeze strong spring 25. After block 23 is fully inserted, under the push of strong spring 25, block 23 can be inserted into slot 27, thereby quickly installing filter barrel 8 to improve work efficiency.

[0035] Reference Figure 2 and Figure 5 A connecting plate 13 is fixedly connected to the outer periphery of the stirring rod 10. A round rod 16 is slidably connected to the middle of the connecting plate 13. A stop block 14 is fixedly connected to one end of the round rod 16, and a scraper 15 is fixedly connected to the other end of the round rod 16. A compression spring 17 is sleeved on the outer periphery of the round rod 16. The scraper 15 is in contact with the inner wall of the tank 2. While stirring and mixing the waste white oil and sodium hydroxide aqueous solution, the stirring rod 10 drives the connecting plate 13 to rotate. At the same time, the scraper 15 can rotate along with the round rod 16, and the compression spring 17 pushes the scraper 15 to keep it close to the inner wall of the tank 2, so that the scraper 15 can clean the inner wall of the tank 2, thereby preventing the waste white oil from adhering to the inner wall of the tank 2 and ensuring mixing efficiency.

[0036] Reference Figure 3 A sealing ring 18 is fixedly connected to the top of the top ring 19. The sealing ring 18 improves the sealing performance of the oil pipeline after it is connected to the connecting pipe 6, thus preventing waste oil leakage.

[0037] Working principle: First, waste white oil is input through connecting pipe 6. Under the action of filter barrel 8 at the bottom of connecting pipe 6, larger impurities can be filtered, thereby ensuring the mixing efficiency of waste white oil and sodium hydroxide aqueous solution and avoiding impurities clogging the pipe. After a long period of filtration, pressing push block 21 causes push rod 20 to push push plate 22, so that push plate 22 pushes block 23 into slide groove 26, thereby allowing top ring 19 to be removed from the middle of sleeve 5, so that impurities in filter barrel 8 can be poured out, ensuring the filtration effect of filter barrel 8.

[0038] When the stirring rod 10 stirs and mixes the waste white oil and sodium hydroxide aqueous solution, the stirring rod 10 will drive the connecting plate 13 to rotate together. At the same time, the scraper 15 can rotate together with the connecting plate 13 under the connection of the round rod 16. Under the push of the compression spring 17, the scraper 15 can stick tightly to the inner wall of the tank 2 and clean it, thereby preventing the waste white oil from adhering to the inner wall of the tank 2 and ensuring mixing efficiency.
