Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of finished product filtration devices for lubricating oil, specifically a finished product filtration device for producing lubricating oil by regenerating waste mineral oil. Background Technology
[0002] The recycling of waste mineral oil into lubricating oil is an important process of resource recycling. Waste mineral oil is processed through pretreatment, distillation, and refining to remove impurities and harmful substances, ultimately producing lubricating oil base oil.
[0003] In existing technologies, after waste mineral oil is processed through pretreatment, distillation, refining and other processes to produce finished lubricating oil, the finished lubricating oil needs to be filtered again to ensure the cleanliness of the lubricating oil.
[0004] Most existing lubricating oil filtration devices use static filters for filtration. These devices typically include a container with a filter screen installed inside. The lubricating oil passes through the filter screen under the action of gravity or pressure, achieving solid-liquid separation. However, since the filter screen is stationary, the filtration speed is slow, which seriously affects the filtration efficiency of the finished lubricating oil. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: a filter box, wherein a retaining frame is fixedly connected to the top four sides of the filter box, an extension plate and a support frame are provided on both sides of the retaining frame, a filter cylinder is fixedly connected to the middle of the two sets of support frames, and a rotating shaft is rotatably connected to the top two sides of the filter cylinder, the two sets of rotating shafts are inserted into the inside of the support frame, and the support frame is fixedly connected to the inner side of the two sets of rotating shafts.
[0007] Preferably, the top of the filter cylinder is equipped with a cylinder cover, the middle of the cylinder cover is provided with an oil inlet, the oil inlet is aligned with the middle of the filter cylinder, and the bottom of the filter cylinder is provided with an oil outlet.
[0008] Preferably, the support frame is located in the middle of the filter cylinder, the retaining frame is held in place on the support frame, and the two ends of the support frame are connected to the rotating shafts. The outer ends of a set of rotating shafts are inserted into the ends of stepper motors located on the outside of the filter cylinder. The stepper motors can drive the rotating shafts to rotate, causing the rotating shafts to drive the support frame to swing left and right in the support frame.
[0009] Preferably, a filter box is provided on the inner bottom of the holding frame, and the oil inlet in the middle of the cylinder cover is aligned with the middle of the filter box, so that the filter box can filter the lubricating oil entering from the oil inlet.
[0010] Preferably, the clamping frame is provided with extension plates on both sides, and a telescopic groove is provided on the bottom inner side of the extension plate. Springs are provided on both sides of the telescopic groove. One end of the spring is connected to the inside of the telescopic groove, and the other end is connected to a limiting block. The limiting block extends out of the telescopic groove and can be clamped at the bottom of the support frame.
[0011] Preferably, a pull rod is connected to the inner center of the limiting block. The pull rod extends out of the limiting block and is located on the outer side of the extension plate. Pulling the pull rod can cause the pull rod to drive the limiting block to compress the spring and retract into the telescopic groove.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] The present invention proposes that when filtering finished lubricating oil, the stepper motor is first started, which drives the rotating shaft to make the support frame swing left and right inside the support frame. While the support frame is swinging, the clamping frame held on the support frame swings, causing the filter screen box at the bottom of the clamping frame to start to shake left and right. Then, the finished lubricating oil is poured into the support frame through the oil inlet in the middle of the cylinder cover. At this time, the lubricating oil falls straight into the filter screen box for filtration, and the filtration is accelerated by the swing of the filter screen box. Attached Figure Description

It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] Please see Figures 1 to 5 This utility model provides a technical solution: a filter box 10, with a retaining frame 9 fixedly connected to the top perimeter of the filter box 10. Extension plates 11 and support frames 1 are provided on both sides of the retaining frame 9. A filter cylinder 2 is fixedly connected to the middle of the two sets of support frames 1. Rotary shafts 4 are rotatably connected to the top sides of the filter cylinder 2. The two sets of rotating shafts 4 are inserted into the interior of the support frames 1, and a support frame 8 is fixedly connected to the inner side of the two sets of rotating shafts 4. A cylinder cover 5 is installed on the top of the filter cylinder 2, with an oil inlet 6 in the middle of the cover 5, which is aligned with the middle of the filter cylinder 2. An oil outlet 7 is provided at the bottom of the filter cylinder 2. The support frame 8 is located in the middle of the interior of the filter cylinder 2. The retaining frame 9 is held in place on the support frame 8. Rotary shafts 4 are connected to both ends of the support frame 8. The outer end of one set of rotating shafts 4 is inserted into the end of a stepper motor 3 located on the outer side of the filter cylinder 2. The stepper motor 3 can drive the rotating shafts 4 to rotate, causing the filter cylinder 2 to rotate. Shaft 4 drives the support frame 8 to swing left and right in the support frame 1; a filter box 10 is provided on the inner bottom of the clamping frame 9, and the oil inlet 6 opened in the middle of the cylinder cover 5 is aligned with the middle of the filter box 10. The filter box 10 can filter the lubricating oil entering from the oil inlet 6; extension plates 11 are provided on both sides of the clamping frame 9, and a telescopic groove 12 is opened on the inner bottom of the extension plate 11. Springs 13 are provided on both sides of the telescopic groove 12. One end of the spring 13 is connected to the inside of the telescopic groove 12, and the other end is connected to the limiting block 14. The limiting block 14 extends out of the telescopic groove 12 and can be clamped at the bottom of the support frame 8; a pull rod 15 is connected to the inner middle of the limiting block 14. The pull rod 15 extends out of the limiting block 14 and is located on the outside of the extension plate 11. Pulling the pull rod 15 can cause the pull rod 15 to drive the limiting block 14 to squeeze the spring 13 and retract into the telescopic groove 12.
[0022] In actual use, when filtering finished lubricating oil, first start the stepper motor 3, which drives the rotating shaft 4 to make the support frame 8 swing left and right inside the support frame 1. While the support frame 8 is swinging, the clamping frame 9 held on the support frame 8 is also swinging, causing the filter screen box 10 at the bottom of the clamping frame 9 to start to shake left and right. Then, the finished lubricating oil is poured into the support frame 1 through the oil inlet 6 in the middle of the cylinder cover 5. At this time, the lubricating oil falls straight into the filter screen box 10 for filtration, and is quickly filtered by the swing of the filter screen box 10, which speeds up the filtration efficiency. After filtering for a period of time, the cylinder cover 5 is removed, and then the pull rod 15 is pulled, which causes the pull rod 15 to drive the limit block 14 to squeeze the spring 13 and retract into the telescopic groove 12, thus releasing the limit on the clamping frame 9. Then, the clamping frame 9 is lifted upwards, and the clamping frame 9 and the filter screen box 10 can be quickly removed for easy cleaning of the filter screen box 10.
