Description

Technical Field

[0001] This application relates to the field of filtration technology, specifically a waste oil filtration device. Background Technology

[0002] A waste engine oil filtration system is a specialized device for treating waste engine oil. It removes impurities and particulate matter from the oil through a filtration system, thereby increasing its recycling value. The system is designed to reduce the consumption of new engine oil, lower maintenance costs, and contribute to environmental protection by reducing pollution to soil and water resources.

[0003] For example, patent CN212731275U discloses a waste oil filtration device. The filtered waste oil flows out from the second filter screen, then flows into the funnel through the lower opening of the impurity collection tank, and then flows into the oil storage tank from the funnel. This avoids the waste oil from splashing everywhere after flowing out of the lower opening of the impurity collection tank and polluting the environment.

[0004] In the actual filtration process, when waste oil passes through the filter screen, solid particles and impurities are intercepted and adhered to the filter screen. With long-term use, the filtration effect may decrease. However, during the cleaning of impurities on the filter screen, the impurities may adhere to the cleaning tools due to their strong adhesion, which can easily cause secondary contamination of the filter screen and affect the cleaning progress.

[0005] Therefore, it is necessary to provide a waste oil filtration device to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0016] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0018] like Figures 1-2 As shown, this application provides a waste oil filtration device, including a housing 1 and a filtration mechanism 2 disposed inside the housing 1. The filtration mechanism 2 is used to filter waste oil. The filtration mechanism 2 includes a fixed frame 20 fixedly disposed inside the housing 1, and a filter screen 21 is fixedly disposed on the fixed frame 20. The filter screen 21 is used to filter waste oil. Meanwhile, the fixing frame 20 divides the interior of the cover 1 into a filtering chamber 22 and a temporary storage chamber 23 through the filter screen 21. The filtering chamber 22 is used to place unfiltered waste oil, and the temporary storage chamber 23 is used to temporarily store the filtered waste oil. At the same time, an inlet 24 is fixedly provided at the upper end of the cover 1. The inlet 24 is connected to the filtering chamber 22 so that the waste oil can be introduced into the filtering chamber 22. An outlet 25 is fixedly provided on one side of the upper end of the cover 1. The outlet 25 is connected to the temporary storage chamber 23 so that the filtered waste oil can be discharged smoothly. like Figures 1-4As shown, in order to prevent the oil stains adhering to the filter screen 21 from accumulating during long-term use and thus affecting the filtration effect, a scraping mechanism 3 is provided inside the filter chamber 22. The scraping mechanism 3 is used to scrape off the oil stains on the upper end of the filter screen 21. The scraping mechanism 3 includes a motor 30 fixedly installed on the upper end of the cover 1. The output end of the motor 30 is fixedly provided with a rotating shaft 31, and the rotating shaft 31 extends into the filter chamber 22. Thus, starting the motor 30 can drive the rotating shaft 31 to rotate inside the filter chamber 22. Meanwhile, a stabilizing frame 32 is fixedly installed on the rotating shaft 31. A guide rail 33 is fixedly installed on the stabilizing frame 32, and a scraper 34 is slidably installed on the guide rail 33. A cylinder 350 is fixedly installed on the stabilizing frame 32. The output end of the cylinder 350 is fixedly connected to the scraper 34. Thus, starting the cylinder 350 can push the scraper 34 to move along the direction of the guide rail 33. After filtration is completed, the motor 30 can be started to drive the scraper 34 to rotate inside the filter chamber 22 through the rotating shaft 31. While rotating, the cylinder 350 can be started to push the scraper 34 closer to the filter screen 21 so as to scrape off the oil stains inside the filter screen 21. Furthermore, a slag discharge port 36 is fixedly provided directly below the cover 1. The slag discharge port 36 is connected to the filter chamber 22, so that the scraped oil can be discharged. Meanwhile, in order to prevent oil stains from adhering to the scraper 34 after scraping off the oil stains, thereby causing secondary pollution to the filter screen 21, a cleaning component 35 is fixedly installed on the stabilizer 32. The cleaning component 35 includes a connecting plate 351 fixedly installed on the stabilizer 32, and a fixing rod 352 fixedly installed at the other end of the connecting plate 351. A scraper 353 is fixedly installed on the fixing rod 352. When it is necessary to clean the scraper 34, the scraper 34 can be driven to move away from the filter screen 21 along the guide rail 33 by starting the cylinder 350. During the movement, the scraper 353 can scrape off the oil stains on the surface of the scraper 34. When it is necessary to scrape off the oil stains on the filter screen 21, the cylinder 350 can push the scraper 34 to extend and fit against the filter screen 21 to clean the surface of the filter screen 21. After scraping is completed, the cylinder 350 drives the scraper 34 to retract. During the retraction process, the scraper 353 can scrape off the oil stains attached to the surface of the scraper 34 and discharge them through the slag discharge port 36.
