Description

Technical Field

[0001] This utility model relates to the field of mineral oil filtration technology, and in particular to a waste mineral oil filtration and separation device. Background Technology

[0002] With the continuous progress of industrialization, mineral oil is increasingly used in many fields such as machinery and transportation. As a result, the amount of waste mineral oil generated is also increasing year by year, which not only leads to the waste of resources, but also causes serious pollution to the environment.

[0003] To improve the recycling efficiency of waste mineral oil, it is particularly important to recycle it. In this process, it is crucial to effectively filter the impurities in the waste mineral oil. Usually, a filter screen is used for coarse filtration and separation. However, a large number of impurities will exist on the inlet surface of the filter screen and accumulate on the filter screen, which is not easy to clean.

[0004] In addition, for waste mineral oil located in high-altitude, desert or arid climate zones, the temperature difference between day and night is usually significant when filtering and separating waste mineral oil. When the mineral oil passes through the filter screen, the ambient temperature is lower at night, and the temperature difference will cause the mineral oil to condense on the liquid outlet surface of the filter screen, affecting the filtration effect of the filter screen. Utility Model Content

[0005] The purpose of this invention is to solve the problem that a large amount of impurities accumulate on the surface of the filter screen in the prior art, affecting the filtration efficiency, and to propose a waste mineral oil filtration and separation device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0014] 1.

[0026] Example:

[0027] Reference Figures 1-6 A waste mineral oil filtration and separation device includes a cylindrical working cylinder 1. A support frame is provided at the bottom of the working cylinder 1 to accommodate waste mineral oil and support the working cylinder 1. A filter screen cylinder 2 is fixedly connected inside the cavity of the working cylinder 1, and the axis of the filter screen cylinder 2 coincides with the axis of the working cylinder 1. A hollow tube 3 is rotatably connected inside the filter screen cylinder 2. A scraper 5 is fixedly connected to the hollow tube 3 through a connecting pipe 4, and the hollow tube 3 and the connecting pipe 4 are connected. A flow channel is opened inside the scraper 5, and the flow channel is connected to the connecting pipe 4. The tip of the scraper 5 is in contact with the inner wall of the filter screen cylinder 2. At least one set of flat nozzles 6 are connected to the upper part, the flow channel is connected to the flat nozzles 6, and the flat nozzles 6 are connected to the hollow tube 3. The output end of the flat nozzles 6 faces the inner wall of the filter cylinder 2. A pressurized liquid delivery component is provided on the working cylinder 1. When the scraper 5 moves along the inner wall of the filter cylinder 2, the pressurized liquid delivery component delivers oil to the flat nozzles 6, thereby causing the flat nozzles 6 to spray oil towards the inner wall of the filter cylinder 2, so as to circulate and backwash the impurities and condensed mineral oil on the inner wall of the filter cylinder 2. At the same time, the scraper 5 can cooperate with the flat nozzles 6 to scrape off the impurities and condensed mineral oil on the inner wall.

[0028] In the above scheme, when the hollow tube 3 rotates, it can drive the scraper 5 to move along the inner wall of the filter cylinder 2. The pressurized infusion assembly will deliver oil to the flat nozzle 6, which will spray oil towards the inner wall of the filter cylinder 2. This spray cleaning can effectively remove impurities and condensed mineral oil attached to the filter cylinder 2. When the scraper 5 performs physical cleaning, it ensures that the filter cylinder 2 can work continuously and effectively, preventing impurities from accumulating on the liquid outlet surface of the filter cylinder 2, so that it can be automatically cleaned. In addition, for waste mineral oil located in high-altitude, desert or dry climate areas, the temperature difference between day and night is usually significant when filtering and separating waste mineral oil. When the mineral oil passes through the filter on the filter cylinder 2, the ambient temperature is low at night. The temperature difference will cause the mineral oil to condense on the liquid outlet surface of the filter. Through the above-mentioned combination of oil spraying and scraping, the filtration efficiency of the filter cylinder 2 can be improved.

[0029] Furthermore, the flat nozzles 6 are evenly distributed along the edge line of the scraper 5, with at least one set. The specific arrangement can be determined according to the length of the filter cylinder 2. The flat spray nozzles 6 are parallel to the axis of the filter cylinder 2, which ensures that the inner wall of the filter cylinder 2 can be evenly sprayed during the movement of the scraper 5. The spraying of multiple sets of flat nozzles 6 helps to improve the coverage of backwashing, and the parallel flat spray nozzle design allows the sprayed oil to be directly concentrated on the inner wall of the filter cylinder 2 and backwashed, improving the spray impact effect.

[0030] The aforementioned pressurized infusion assembly includes: a pressurizing cylinder 16; a circular receiving box 10 fixedly connected to the bottom of the working cylinder 1; the pressurizing cylinder 16 fixedly connected inside the receiving box 10; a transmission disc 14 fixedly connected inside the receiving box 10; a limiting disc 13 fixedly connected to the bottom of the hollow tube 3 inside the transmission disc 14; the limiting disc 13 fitting against the inner wall of the transmission disc 14; when it is necessary to deliver oil into the hollow tube 3, the oil can be directly delivered into the transmission disc 14; during this process, the hollow tube 3 can always rotate; a drain pipe 8 is also fixedly connected to the working cylinder 1; the drain pipe 8 is connected to the filter screen cylinder 2; the filtered mineral oil can be discharged through the drain pipe 8. For subsequent collection from the outside, a second connecting shaft 15 is rotatably connected to the booster cylinder 16. A turbine blade 17 is fixedly connected to the outer wall of the second connecting shaft 15. The turbine blade 17 is set in the cavity of the booster cylinder 16. One side of the booster cylinder 16 is connected to the drain pipe 8 through the inlet pipe 18. A one-way valve is also provided on the inlet pipe 18 so that it can only deliver the filtered mineral oil into the booster cylinder 16. The other side of the booster cylinder 16 is fixedly connected to the transmission disc 14 through the outlet pipe 19. When the second connecting shaft 15 drives the turbine blade 17 to rotate, the filtered mineral oil can be pressurized and delivered into the transmission disc 14, and then delivered into the hollow tube 3 by the transmission disc 14.

[0031] Reference Figure 5 and Figure 6 To facilitate the cyclic rotation of the hollow tube 3, a motor 11 is fixedly connected inside the storage box 10. The motor 11 can be a hydraulic motor 11 or a high-torque motor 11. The output end of the motor 11 is fixedly connected to a first connecting shaft 12. A main gear is provided on the first connecting shaft 12, and a transmission gear is provided on the outer wall of the hollow tube 3. The main gear meshes with the transmission gear. An auxiliary gear is fixedly connected to the outer wall of the second connecting shaft 15. The auxiliary gear meshes with the transmission gear. When the motor 11 drives the first connecting shaft 12 to rotate, the main gear can drive the transmission gear to rotate, thereby causing the hollow tube 3 to rotate synchronously. When the first connecting shaft 12 rotates three times, the hollow tube 3 rotates one time. When the hollow tube 3 rotates one time, the transmission gear can drive the auxiliary gear to rotate four times synchronously, thereby causing the turbine blades 17 to rotate synchronously, pressurizing the mineral oil and delivering it to the flat nozzle 6.

[0032] A feed hopper 7 is provided at the top of the working cylinder 1, and its output end is connected to the cavity of the working cylinder 1 for inputting unfiltered mineral oil.
