Description

Technical Field

[0001] The utility model relates to the technical field of waste lubricating oil treatment, in particular to a waste lubricating oil recovery device. Background Art

[0002] Waste lubricating oil, also known as waste engine oil, mainly comes from the deterioration caused by the mixing of various impurities (such as moisture, dust, other miscellaneous oils, and metal powder produced by wear of machine parts) during the use of the engine oil, as well as the gradual oxidation and deterioration of the engine oil itself to produce organic acids, gums and asphalt-like substances.

[0003] Filtration, a key step in the waste lubricating oil recovery process, has traditionally relied on simple screens or filters to remove impurities and residues. However, this approach has significant drawbacks: the large amounts of solid particles, metal debris, and other impurities found in waste lubricating oil easily accumulate on the inner walls of the screen or filter during the filtration process, causing clogging. Clogging not only reduces filtration efficiency and affects the purity of the recovered oil, but in severe cases can even interrupt the entire recovery process, forcing the screen or filter to be cleaned and replaced. This prolongs the waste lubricating oil's processing cycle, increases processing costs, and reduces the reusability of the recovered oil.

[0004] Therefore, in order to solve the shortcomings of the above problems, a waste lubricating oil recovery device is proposed. Summary of the Invention

[0005] The utility model overcomes the shortcomings of the prior art and provides a device for recovering waste lubricating oil.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a waste lubricating oil recovery device, comprising: a collection barrel, and a filtering mechanism arranged in the collection barrel;

[0007] The filtering mechanism includes: a mounting frame, a motor arranged in the mounting frame, a filter cartridge arranged on the upper surface of the mounting frame, a rotating rod arranged on the inner wall of the bottom of the filter cartridge, and a plurality of scraping rods arranged on the inner wall of the circumference of the filter cartridge;

[0008] The bottom inner wall of the collecting barrel is fixedly connected with a fixing rod, the top of the fixing rod is fixedly connected to the bottom of the mounting frame, a mounting groove is provided in the mounting frame, the bottom of the motor is fixedly connected to the bottom inner wall of the mounting groove, the filter cartridge is fixedly connected to the top of the mounting frame, the rotating rod is rotatably connected to the bottom inner wall of the filter cartridge, and the circumferential outer wall of the rotating rod is fixedly connected with a plurality of connecting rods, and the other ends of the plurality of connecting rods are respectively fixedly connected to a plurality of scraping rods.

[0009] In a preferred embodiment of the present invention, the outer walls of the plurality of scraping rods are tightly fitted with the circumferential inner wall of the filter cylinder.

[0010] In a preferred embodiment of the present invention, a retaining ring is fixedly connected to the top of the filter cartridge.

[0011] In a preferred embodiment of the present invention, a guide plate is fixedly connected to the circumferential outer wall of the installation frame.

[0012] In a preferred embodiment of the present invention, a plurality of guide grooves are formed on the circumferential outer wall of the guide plate.

[0013] In a preferred embodiment of the present invention, a liquid isolation plate is fixedly connected to the top of the collection barrel.

[0014] In a preferred embodiment of the present invention, the bottom of the installation frame is flush with the upper surface of the collection bucket.

[0017] In a preferred embodiment of the present invention, the bottom pipe of the collection barrel is connected to a guide pipe.

[0018] The present invention solves the defects in the background technology and has the following beneficial effects:

[0019] (1) The utility model provides a waste lubricating oil recovery device. Through the arrangement of the scraper rod, the scraper rod is closely fitted to the circumferential inner wall of the filter cartridge. Driven by the motor, the rotating rod drives the scraper rod to rotate, effectively scraping off the waste lubricating oil residue and impurities attached to the inner wall of the filter cartridge, avoiding the clogging problem caused by the accumulation of impurities in the traditional filtering method, significantly improving the filtering efficiency and purity, thereby shortening the processing cycle of the waste lubricating oil, and ensuring the quality of the recovered oil, providing a reliable guarantee for subsequent reuse.

[0020] (2) The present invention provides a waste lubricating oil recovery device. The heat dissipation holes provided at the bottom of the mounting frame effectively promote heat dissipation during operation of the motor, thereby extending the service life of the device. At the same time, the arrangement of the guide plate and the guide groove thereon allows the lubricating oil that has undergone preliminary filtration to flow more smoothly into the collection barrel, reducing the retention time of the liquid in the device, further preventing the deposition of impurities, and enhancing the practicality and ease of maintenance of the device. In addition, the arrangement of the liquid partition plate effectively isolates the upper operating area from the lubricating oil collection area, keeping the working environment clean and tidy.

[0021] (3) The present invention provides a waste lubricating oil recovery device, which is firmly supported by support legs. This not only facilitates flexible deployment in different locations but also ensures stability during operation. The outlet pipe allows the filtered lubricating oil to be easily discharged, facilitating subsequent processing or storage, thereby improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0027] like Figure 1 As shown, a waste lubricating oil recovery device comprises: a collecting barrel 1, and a filtering mechanism 3 arranged in the collecting barrel 1;

[0028] like Figure 1-Figure 2 As shown, the filtering mechanism 3 includes: a mounting frame 301, a motor 307 disposed in the mounting frame 301, a filter cartridge 302 disposed on the upper surface of the mounting frame 301, a rotating rod 308 disposed on the bottom inner wall of the filter cartridge 302, and a plurality of scraping rods 304 disposed on the circumferential inner wall of the filter cartridge 302;

[0029] The bottom inner wall of the collecting barrel 1 is fixedly connected with a fixing rod 8, the top of the fixing rod 8 is fixedly connected to the bottom of the mounting frame 301, a mounting groove is opened in the mounting frame 301, the bottom of the motor 307 is fixedly connected to the bottom inner wall of the mounting groove, the filter cartridge 302 is fixedly connected to the top of the mounting frame 301, the rotating rod 308 is rotatably connected to the bottom inner wall of the filter cartridge 302, and the circumferential outer wall of the rotating rod 308 is fixedly connected with a number of connecting rods 305, and the other ends of the several connecting rods 305 are respectively fixedly connected to a number of scraping rods 304, and the outer walls of the several scraping rods 304 are tightly fitted with the circumferential inner wall of the filter cartridge 302.

[0030] It should be noted that the motor 307 drives the rotating rod 308 to rotate, thereby driving the connecting rod 305 and the scraper rod 304 to scrape the circumferential inner wall of the filter cylinder 302, effectively removing the waste lubricating oil residue and impurities attached to the inner wall of the filter cylinder 302, thereby improving the filtration efficiency, avoiding the blockage and decreased filtration efficiency caused by impurity accumulation in traditional filtration methods, and ensuring that the waste lubricating oil can pass through the filter cylinder 302 continuously and stably, thereby improving the purity and quality of the recovered oil.

[0031] like Figure 1-Figure 2 As shown, the top of the filter cartridge 302 is fixedly connected with a retaining ring 303, the circumferential outer wall of the mounting frame 301 is fixedly connected with a guide plate 6, the circumferential outer wall of the guide plate 6 is provided with a plurality of guide grooves 7, the top of the collecting barrel 1 is fixedly connected with a liquid partition plate 2, the bottom of the mounting frame 301 is flush with the upper surface of the collecting barrel 1, the bottom of the mounting frame 301 is provided with a plurality of heat dissipation holes 306, and the plurality of heat dissipation holes 306 are connected with the mounting grooves, the bottom of the collecting barrel 1 is fixedly connected with a plurality of supporting feet 5, and the bottom pipe of the collecting barrel 1 is connected with a guide pipe 4.

[0032] It should be noted that the retaining ring 303 can effectively prevent the waste lubricating oil from splashing out during the filtration process, ensuring the stability and safety of the filtration process. Through the guide plate 6 and the guide groove 7 thereon, the lubricating oil that has been preliminarily filtered can flow more smoothly to the bottom of the collection barrel 1, reducing the residence time of the liquid in the device. Several heat dissipation holes 306 provide an effective heat dissipation channel for the motor 307, reducing the temperature of the motor 307 during operation, extending the service life of the motor 307, and reducing the risk of failure due to overheating. The liquid partition plate 2 fixed on the top of the collection barrel 1 effectively isolates the upper operating area from the lubricating oil collection area, keeps the working environment clean, and reduces the risk of splashing during operation. The outlet pipe 4 facilitates the outlet and collection of the filtered lubricating oil.

[0033] When the present invention is used, the waste lubricating oil is slowly poured into the collection barrel 1, and the motor 307 is started, so that the output shaft of the motor 307 rotates to drive the rotating rod 308 to rotate, and the rotating rod 308 drives the scraping rod 304 to scrape the circumferential inner wall of the filter cylinder 302 through the connecting rod 305, and begins to remove the waste lubricating oil residue and impurities attached to the inner wall of the filter cylinder 302. The filtered lubricating liquid flows into the surface of the guide plate 6, and drips into the collection barrel 1 for storage through the guide groove 7 opened on the upper surface of the guide plate 6.

[0034] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
