Description

Technical Field

[0001] This utility model relates to the field of lubricating oil recycling technology, and in particular to a device for recycling residual lubricating oil. Background Technology

[0002] Against the backdrop of sustained and rapid development in industrial production and transportation, the consumption of lubricating oil, a key medium for the operation of mechanical equipment, has increased dramatically, resulting in a substantial increase in the amount of waste lubricating oil. Although waste lubricating oil has partially deteriorated, it still contains recyclable base oil resources. The research and application of lubricating oil residue recycling devices have become core equipment for achieving resource recycling and promoting green development.

[0003] Existing filter-type lubricating oil residue recovery and utilization devices primarily revolve around the filter screen in their core structure. The main body of the equipment is typically a box-shaped outer shell, inside which the filter screen is installed and fixed. The filter screen is mostly made of metal woven mesh or fiber filter cloth, and is secured inside the filter chamber by bolts, clips, or other methods. During operation, waste oil flows in from the top inlet of the device using gravity flow or manual pumping. After passing through the filter screen, solid impurities such as metal fragments, silt, and fibers in the waste oil are blocked on the filter screen surface. The filtered oil then flows into the storage area below.

[0004] However, these filter-type recycling devices have significant shortcomings in waste oil storage. Their storage areas are typically fixed at the bottom of the device and have limited capacity, making them ill-suited for situations with large fluctuations in waste oil generation. In practical use, such as during peak weekend oil change periods at auto repair shops or concentrated agricultural machinery maintenance operations, large amounts of waste oil generated in a short time can quickly fill the storage space. At this point, workers must frequently interrupt recycling operations to transfer the waste oil from the storage area to other storage containers. This process not only consumes a lot of manpower, requiring workers to repeatedly move and empty the waste oil, but each transfer also takes time, significantly reducing the overall efficiency of waste oil recycling. Therefore, a lubricating oil residue recycling device is proposed to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a device for recycling and utilizing residual lubricating oil, which aims to improve the problem that the recycled waste oil cannot be stored in the prior art.

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

[0007] A device for recycling residual lubricating oil includes a recycling bin, a storage component inside the recycling bin, a filter screen inside the recycling bin, and a quick-release component on the outer wall of the filter screen.

[0008] The storage assembly includes a recycling chamber, the outer wall of which is disposed inside the recycling bin. A slide rail is fixedly connected to the inner wall of the recycling bin. A sliding groove is formed inside the recycling chamber. The inner wall of the sliding groove is slidably connected to the outer wall of the slide rail. A fixing block is fixedly connected to the outer wall of the recycling bin. A sliding groove is formed inside the fixing block. A limit block is slidably connected to the inner wall of the fixing block. A spring is disposed inside the fixing block. One end of the spring is fixedly connected to the inner wall of the fixing block, and the other end of the spring is fixedly connected to the outer wall of the limit block. A pull rod is fixedly connected to the outer wall of the limit block. The outer wall of the pull rod is slidably connected to the inner wall of the sliding groove.

[0009] As a further description of the above technical solution:

[0010] The quick-release assembly includes a locking block, which is disposed on the outer wall of the filter screen, and a handle is fixedly connected to the outer wall of the filter screen;

[0011] As a further description of the above technical solution:

[0012] The bottom of the filter screen is fixedly connected to a guide post, and the inner wall of the recycling bin is fixedly connected to a fixing frame.

[0013] As a further description of the above technical solution:

[0014] The fixing frame has a limiting hole inside, and the outer wall of the guide post is slidably connected to the inner wall of the limiting hole;

[0015] As a further description of the above technical solution:

[0016] A connecting rod is fixedly connected to the bottom of the filter screen, and a second locking block is fixedly connected to the outer wall of the connecting rod;

[0017] As a further description of the above technical solution:

[0018] The inner wall of the fixed frame is slidably connected to a first locking block, and the outer wall of the first locking block is in contact with the outer wall of the second locking block;

[0019] As a further description of the above technical solution:

[0020] A second spring is provided on the outer wall of the first card block. One end of the second spring is fixedly connected to the outer wall of the first card block, and the other end of the second spring is fixedly connected to the inner wall of the fixing frame.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the limiting block is moved by pulling the lever, and then the spring is compressed by the movement of the limiting block, which achieves the effect of installing and disassembling the recycling chamber. This avoids the need for frequent transfer of waste oil to the storage location after collection when there is no recycling chamber, which consumes a lot of manpower and time and greatly reduces work efficiency. By replacing the recycling chamber, more waste oil can be stored, the frequency of transfer can be reduced, time and labor costs can be saved, and the overall recycling work efficiency can be improved.

[0023] 2. In this utility model, the filter screen is moved by pulling the handle upwards, and then the connecting rod is moved by the movement of the filter screen, which achieves the effect of quick disassembly of the filter screen. This avoids the cumbersome disassembly method of the traditional filter screen, which takes a long time to disassemble and clean each time, causing the equipment to be shut down for a long time and affecting the waste oil treatment progress. As a result, the filter screen can be quickly disassembled, the cleaning time is greatly shortened, the equipment downtime is reduced, and the waste oil treatment efficiency is improved.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 This utility model provides an embodiment of a lubricating oil residue recycling device, including a recycling tank 1. The recycling tank 1 provides installation support and protection for the internal components, achieving the effect of supporting the entire waste oil recycling process. The recycling tank 1 contains a storage component and a filter screen 2. The outer wall of the filter screen 2 is equipped with a quick-release component. The storage component includes a recycling chamber 4, which stores the filtered waste oil, achieving temporary storage and reducing the frequency of transfer. The outer wall of the recycling chamber 4 is located inside the recycling tank 1. A slide rail 3 is fixedly connected to the inner wall of the recycling tank 1. A sliding groove 18 is opened inside the recycling chamber 4. The inner wall of the sliding groove 18 is slidably connected to the outer wall of the slide rail 3, forming a clearance fit between the inner wall of the sliding groove 18 and the outer wall of the slide rail 3, allowing the recycling chamber 4 to smoothly move along the slide rail 3. When the recycling chamber 4 is pushed into the recycling box 1, a fixed block 5 is fixedly connected to the outer wall. The fixed block 5 has a sliding groove 6 inside. The limiting block 7 moves linearly in cooperation with the sliding groove 6 to lock or unlock the recycling chamber 4. The inner wall of the fixed block 5 is slidably connected to the limiting block 7. The fixed block 5 has a spring 8 inside. One end of the spring 8 is fixedly connected to the inner wall of the fixed block 5, and the other end of the spring 8 is fixedly connected to the outer wall of the limiting block 7. The outer wall of the limiting block 7 is fixedly connected to the pull rod 9. The outer wall of the pull rod 9 is slidably connected to the inner wall of the sliding groove 6. When the recycling chamber 4 is pushed into the recycling box 1, the limiting block 7 moves to the outer wall of the recycling chamber 4 under the elastic force of the spring 8, and fixes it firmly. When the pull rod 9 is pulled, the pull rod 9 drives the limiting block 7 to move against the elastic force of the spring 8, thereby unlocking the recycling chamber 4 and facilitating installation and disassembly.

[0035] Reference Figure 1 and Figures 4-7The quick-release assembly includes a locking block 14, which, in conjunction with a spring 15, engages with a locking block 17 to achieve a quick fixation of the filter screen 2. The locking block 14 is located on the outer wall of the filter screen 2, and a handle 10 is fixedly connected to the outer wall of the filter screen 2. The handle 10 facilitates the gripping and removal of the filter screen 2 by the operator. A guide post 11 is fixedly connected to the bottom of the filter screen 2. The guide post 11 engages with a limiting hole 13 to accurately position the filter screen 2 during installation, ensuring it is properly installed. A fixing frame 12 is fixedly connected to the inner wall of the recycling bin 1. The fixing frame 12 has a limiting hole 13 inside, allowing the guide post 11 to slide along its outer wall. A connecting rod 16 is fixedly connected to the bottom of the filter screen 2, which is connected to the inner wall of the limiting hole 13. A second locking block 17 is fixedly connected to the outer wall of the connecting rod 16. A first locking block 14 is slidably connected to the inner wall of the fixing frame 12. The outer walls of the first locking block 14 and the second locking block 17 are in contact. A second spring 15 is provided on the outer wall of the first locking block 14. One end of the second spring 15 is fixedly connected to the outer wall of the first locking block 14, and the other end is fixedly connected to the inner wall of the fixing frame 12. When the handle 10 is pulled upward, the filter screen 2 moves the connecting rod 16 upward. The second locking block 17 pushes the first locking block 14 to compress the second spring 15, thereby releasing the lock on the filter screen 2 and realizing the quick disassembly of the filter screen 2. The disassembled filter screen 2 can be directly cleaned or replaced, greatly shortening the cleaning time, reducing equipment downtime, and improving waste oil treatment efficiency.

[0036] Working principle: When removing the recycling chamber 4, first pull the lever 9, which moves the limiting block 7. Then, the movement of the limiting block 7 compresses the spring 8. When the limiting block 7 moves out of the outer wall of the recycling chamber 4, it releases its limitation. Then, by pulling the recycling chamber 4 outward, it slides on the outer wall of the slide rail 3 through the inner wall of the sliding groove 18, thus removing the recycling chamber 4. This avoids the need for frequent transfer of waste oil to the storage location after collection when there is no recycling chamber 4, which consumes a lot of manpower and time and greatly reduces work efficiency.

[0037] When disassembling filter screen 2, first pull handle 10. Pulling handle 10 moves filter screen 2, which in turn moves connecting rod 16. The movement of connecting rod 16 then moves locking block 17, which in turn presses locking block 14. Locking block 14 then compresses spring 15, and locking block 14 releases the restriction on locking block 17, completing the disassembly of filter screen 2. When installing filter screen 2, first slide guide post 11 against the inner wall of limiting hole 13, then press handle 10 downwards. By pressing the handle 10, the connecting rod 16 is moved, and the movement of the connecting rod 16 moves the second locking block 17. The movement of the second locking block 17 squeezes the first locking block 14, and the movement of the first locking block 14 compresses the second spring 15. When it reaches the designated position, the spring 2 rebounds and drives the first locking block 14 to reset. The reset of the first locking block 14 then limits the second locking block 17, completing the installation of the filter screen 2. This avoids the cumbersome disassembly method of the traditional filter screen 2, which is time-consuming and causes long downtime of equipment, affecting the waste oil treatment progress.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
