Description

Technical Field

[0001] The invention belongs to the technical field of engine oil recovery, and in particular to a waste engine oil recovery device. Background Art

[0002] In the mineral processing process, cone crushers are used to crush the ore, breaking the large-sized ore into more uniform small-sized ore. The small-sized ore is then further processed by a grinding mill to turn the ore into powder, which is convenient for subsequent magnetic separation and flotation processes.

[0003] During the operation of the cone crusher and mill, due to the high work intensity and severe wear, it is necessary to inject oil into the cone crusher and mill to lubricate and cool the related components. After the cone crusher and mill have been used for a period of time, the oil in the machine needs to be drained and new oil needs to be injected to ensure the normal operation of the equipment. The used oil contains a large amount of impurities. If it needs to be reused, the oil needs to be filtered. After filtering the oil for a period of time, the existing recovery device will attach a large amount of impurities to the filter element and clog the mesh, affecting the filtering efficiency. Therefore, the filter element needs to be manually removed and replaced. During the replacement process, the operator is easily contaminated with oil, which makes the subsequent cleaning of the oil more troublesome. In addition, the filter element needs to be cleaned after use for the next time, which increases the labor intensity. Summary of the Invention

[0004] In response to the above problems, the purpose of the present invention is to provide a waste oil recovery device, which uses a suction hood to extract impurities that block the mesh holes on the filter plate and bring the impurities to a guide pipe for discharge, replacing manual cleaning of the filter plate and avoiding the need to disassemble the filter plate, thereby reducing the labor intensity of disassembling and cleaning the filter plate and avoiding contamination of the operator's clothes by the oil during the disassembly process.

It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0028] The following combination Figures 1-6 The present invention is described in detail.

[0029] Example

[0030] A waste oil recovery device, such as Figure 1 As shown, it includes a box body 1 and a filter plate 13 arranged in the box body 1, and a suction hood 11 is movably provided above the filter plate 13, which is in sealing contact with the upper surface of the filter plate 13, and the suction hood 11 is connected to a driving device for driving the suction hood 11 to move horizontally. The suction hood 11 is connected to a suction device through a hose 8, and one end of the filter plate 13 is connected to a guide tube 16 adapted to the lower end opening of the suction hood 11, and the lower end of the guide tube 16 is connected to the outside of the box body 1, and a sealing plate 15 for sealing the pipe opening of the guide tube 16 is movably provided on the upper surface of the filter plate 13.

[0031] Before suction, the sealing plate 15 needs to be opened to expose the nozzle of the guide tube 16; driven by the driving device, the suction hood 11 can perform horizontal reciprocating motion. During the motion, the suction device sucks the air in the suction hood 11 through the hose 8, and negative pressure is generated in the suction hood 11, thereby sucking impurities blocking the mesh out of the mesh; when the suction hood 11 moves to the nozzle of the guide tube 16, suction is stopped, and the impurities flow out of the box 1 along the guide tube 16, thereby completing the cleaning operation of the filter plate 13.

[0032] The filter element of the present application adopts a filter plate 13, which can better fit the suction hood 11 and ensure the suction efficiency of the suction hood 11. A feed hopper 3 is provided on the top of the box body 1. During filtering, oil is added to the box body 1 from the feed hopper 3; an oil drain pipe 2 is provided at the bottom of the box body 1 to facilitate the discharge of filtered oil.

[0033] like Figure 3 As shown, both sides of the suction hood 11 are sealed against the inner wall of the box body 1. After the suction hood 11 is in contact with the inner wall of the box body 1, the suction hood 11 acts as a scraper, first scraping off the impurities accumulated on the filter plate 13, and then sucking the mesh to prevent the accumulated impurities from affecting the suction effect, thereby ensuring that the suction force can suck out the impurities in the mesh.

[0034] The suction device is arranged outside the box body 1, and the hose 8 is movable through the box body 1. Two rollers 9 for clamping the hose 8 are rotatably arranged on the outer wall of the box body 1. Figure 4 As shown, the roller 9 is provided with an arcuate groove 26 along the circumference for placing the hose 8, and the roller 9 is connected to a first motor 25. The two rollers 9 rotate simultaneously to control the movement of the clamped hose 8, so that the hose 8 can be conveniently moved together with the suction hood 11, while also ensuring that the hose 8 can be recovered normally. Rubber pads can be laid in the arcuate groove 26 to increase the friction with the hose 8, thereby better controlling the movement of the hose 8. The rotation speed of the first motor 25 needs to be adapted to the movement speed of the suction hood 11, so that the hose 8 always remains in a straight state during the movement of the suction hood 11. As shown Figure 1 As shown, a placement box is also provided on the outside of the box body 1 to facilitate the placement of the hose 8.

[0035] The suction device includes a suction pump 4 connected to a first suction pipe 7 connected to a hose 8. A second suction pipe 5, located below the filter plate 13, is connected to the housing 1. A three-way valve 6 is provided at the junction of the second and first suction pipes 5 and 7. The second suction pipe 5 draws air from below the filter plate 13, creating a negative pressure below the filter plate 13 that accelerates oil filtration and reduces filtration time. By switching the three-way valve 6, either the first or second suction pipe 7 performs the suction operation, reducing the need for the suction pump 4.

[0036] The drive device includes a guide rod 12 that moves laterally through the suction hood 11 and is fixed to the housing 1; and a screw rod 10 that threads laterally through the suction hood 11 and is rotatably connected to the housing 1. The screw rod 10 moves out of the housing 1 and is connected to a second motor 18. The second motor 18 drives the screw rod 10 to rotate, thereby driving the suction hood 11 to move laterally. The guide rod 12 limits the rotation of the suction hood 11.

[0037] like Figure 1 and 2 As shown, a through hole 20 is vertically opened at the top of the suction hood 11, and an annular scraper 24 is movably provided on the inner wall of the suction hood 11. The annular scraper 24 is connected to a tension spring 23 fixed to the top of the suction hood 11, and the annular scraper 24 is connected to a blocking plate 21 for blocking the through hole 20 through a connecting piece 22. The upper surface of the box body 1 is provided with an electric telescopic rod 19 for passing through the through hole 20 to push the annular scraper 24 to move downward.

[0038] When the suction hood 11 is performing suction operation, the blocking plate 21 blocks the through hole 20 to ensure normal suction of the suction hood 11. Some of the impurities sucked out will adhere to the inner wall of the suction hood 11. The annular scraper 24 can prevent the impurities from continuing to move upward along the inner wall and blocking the pipe opening of the hose 8. When the suction hood 11 moves to the top of the guide tube 16, the electric telescopic rod 19 drives the annular scraper 24 to move downward to scrape off the attached impurities, preventing the impurities from accumulating too much and passing over the annular scraper 24 into the hose 8. The specific driving process is as follows: Figure 5 and 6 As shown, the telescopic end of the electric telescopic rod 19 passes through the through hole 20 and pushes open the blocking plate 21. At the same time, the tension spring 23 is stretched, and the blocking plate 21 pushes the annular scraper 24 downward through the connecting piece 22. After the impurities are scraped off, the telescopic end of the electric telescopic rod 19 retracts, and under the elastic force of the tension spring 23, the annular scraper 24 and the blocking plate 21 are reset.

[0039] The sealing plate 15 is movable through the box body 1 and connected to the connecting plate 17. The connecting plate 17 is detachably connected to the box body 1 by screws. After the connecting plate 17 is connected to the box body 1, the sealing plate 15 is kept sealed to the guide tube 16. When the sealing plate 15 needs to be opened, it is only necessary to remove the screws on the connecting plate 17 and pull out the connecting plate 17.

[0040] A baffle 14 is fixedly connected to the upper surface of the sealing plate 15, with both sides of the baffle 14 sealingly attached to the inner wall of the housing 1. The baffle 14, in conjunction with the suction hood 11, controls the filtered oil within the central area of ​​the filter plate 13, preventing oil from migrating to the sides of the housing 1 and accumulating without being filtered, thereby hindering the movement of the suction hood 11. The baffle 14 is movably mounted on the guide rod 12, further enhancing its stability.

[0041] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
