Description

Technical Field

[0001] This utility model relates to the field of oil filtration technology, and more specifically, to an oil filtration device for an extruder gearbox. Background Technology

[0002] The extruder gearbox is a key component of the extruder, mainly composed of gear sets, shaft parts, housing, bearings, lubrication system, and sealing devices. Its power comes from the motor, transmitted to the input shaft via a coupling, and the speed and torque are changed through gear meshing. Then, the output shaft transmits the power to the screw. During operation, it converts the high speed and low torque of the motor into the low speed and high torque required by the screw, precisely controlling the screw speed and ensuring stable power transmission to adapt to the extrusion process requirements of different materials and product specifications. This helps the extruder stably and efficiently extrude materials uniformly. During use, the extruder gearbox generates oil sludge. This oil sludge contains metal debris, oxidized impurities, and external contaminants. If it continues to circulate in the system without filtration, these impurities will accelerate the wear of precision components such as gears and bearings, leading to decreased equipment operating accuracy, shortened equipment lifespan, increased maintenance costs, and downtime. Therefore, oil sludge filtration is necessary.

[0003] A search revealed a Chinese patent application with patent number CN202121134568.4, which discloses a filter structure for oil stains in a gearbox. The filter includes a filter bucket without a top cover. A top plate is provided on the top of the filter bucket. An installation block is fixedly connected to both sides of the top plate. A through-hole is provided through the middle side wall of each of the two installation blocks. A limiting rod is movably connected to each of the two through-holes. A limiting groove is provided on the opposite side of each of the two limiting rods at a position corresponding to the filter bucket. The two limiting rods pass through the two through-holes and are inserted into the two limiting grooves. A support frame is fixedly installed at the center of the upper surface of the top plate.

[0004] While the aforementioned patent utilizes a circular groove, slide, filter plate, slider, and top plate to facilitate the quick sliding of the filter plate out of the circular groove and slide, making it easy to clean the dirt on the filter plate, and uses a drive motor, rotating rod, and bearings to rotate the filter plate in the circular groove, increasing filtration efficiency through centrifugal force, and can fix the top plate with mounting blocks, limiting grooves, and limiting rods to prevent movement when the drive motor starts, and uses a circulating pump, suction pipe, and outlet pipe to draw lubricating oil from the bottom of the filter barrel to the top for multiple filtrations, resulting in good filtration, it still has the following shortcomings during use: 1. The filter plate cannot be replaced, making later maintenance inconvenient and hindering the use of filter plates with different pore sizes to filter oil of different densities; 2. The device requires frequent manual cleaning of the filter plate, necessitating machine shutdown during cleaning, which affects overall work efficiency.

[0005] Therefore, there is an urgent need for an oil filtration device for extruder gearboxes to solve the above problems. Utility Model Content

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0033] like Figure 1-8 As shown, this embodiment proposes an oil filtration device for an extruder gearbox, including a bottom filter barrel 1, an external square chamber 2 fixedly connected to the top wall of the bottom filter barrel 1, a top filter barrel 3 fixedly connected to the top wall of the external square chamber 2, and a feed pipe 6 fixedly connected to the top wall of the top filter barrel 3. Oily liquid enters the top filter barrel 3 through the feed pipe 6, undergoes preliminary filtration by the filter plate 27, and then enters the external square chamber 2 and the bottom filter barrel 1. The device also includes:

[0034] Top positioning plate 23 is fixedly connected to the outer wall of external square compartment 2;

[0035] The components are designed for easy disassembly and replacement. These components include a drawer 15 slidably connected to the outer wall of the external square compartment 2. A handle 16 is fixedly connected to the outer wall of the drawer 15. Symmetrically distributed high-strength springs 26 are fixedly connected to the inner wall of the drawer 15. An adaptive lifting plate 24 is fixedly connected to the top wall of the high-strength springs 26. A bottom positioning plate 25 is fixedly connected to the outer wall of the adaptive lifting plate 24. A locking plate 28 is provided between the bottom positioning plate 25 and the top positioning plate 23. A filter plate 27 is fixedly connected to the outer wall of the locking plate 28. A hexagonal linkage block 29 is fixedly connected to the outer wall of the filter plate 27. When the filter plate 27 needs to be replaced, the drawer is pulled by the handle 16. 15, so that it slides on the outer wall of the outer square compartment 2. The movement of the drawer 15 drives the adaptive lifting plate 24 and the bottom positioning plate 25 to move. Due to the action of the strong spring 26, when the filter plate 27 is squeezed by the top positioning plate 23, it can adaptively adjust its position through the bottom positioning plate 25. When the distance between the bottom positioning plate 25 and the top positioning plate 23 is appropriate, the clamping plate 28 and the filter plate 27 can be removed from between the two. Then, filter plates 27 with different pore sizes can be replaced and then installed back in their original positions. This realizes the easy disassembly and replacement of the filter plate 27, which is convenient for later maintenance and for replacing the appropriate filter plate 27 for oil stains of different densities.

[0036] The self-cleaning component is located on the inner wall of the bottom filter tank 1.

[0037] like Figure 3-4 As shown, in a preferred embodiment, based on the above method, the self-cleaning component further includes a fixing frame 17 symmetrically fixedly connected to the inner wall of the bottom filter barrel 1. A fixing sleeve 18 is fixedly connected to one end of the fixing frame 17 away from the bottom filter barrel 1. A cross-shaped locking block 22 is slidably connected to the top wall of the fixing sleeve 18. A scraper 19 is fixedly connected to the outer wall of the cross-shaped locking block 22, and the scraper 19 is slidably connected to the fixing sleeve 18. The top wall of the scraper 19 abuts against the outer wall of the filter plate 27. When the drive motor 8 starts, the hexagonal drive column 30 at its output end rotates. Since both the hexagonal drive column 30 and the hexagonal linkage block 29 are hexagonal structures, they drive the filter plate 27 to rotate. When the filter plate 27 rotates, the scraper 19, which abuts against its outer wall, cleans the surface of the filter plate 27, scraping off oil stains and other impurities on the filter plate 27. The scraper 19 slides on the fixing sleeve 18 through the cross-shaped locking block 22, which facilitates the replacement and maintenance of the scraper 19 in the future.

[0038] like Figure 1As shown, in a preferred embodiment, based on the above method, a support plate 11 is fixedly connected to the outer wall of the bottom filter tank 1, a circulation pump 12 is fixedly connected to the top wall of the support plate 11, a suction pipe 14 is fixedly connected to the inlet of the circulation pump 12 and is fixedly connected to the bottom filter tank 1, and an outlet pipe 13 is fixedly connected to the outlet of the circulation pump 12 and is fixedly connected to the top filter tank 3. The circulation pump 12 draws out the oil in the bottom filter tank 1 through the suction pipe 14 and sends it back to the top filter tank 3 through the outlet pipe 13, thereby realizing the circulation filtration of the oil and further improving the filtration effect.

[0039] like Figure 3 As shown, in a preferred embodiment, based on the above method, a discharge pipe 20 is fixedly connected to the outer wall of the bottom filter barrel 1, and a valve 21 is provided on the outer wall of the discharge pipe 20. The oil sludge in the bottom filter barrel 1 is further settled under the action of gravity, and then discharged through the discharge pipe 20. The valve 21 on the discharge pipe 20 can control the speed and flow rate of oil discharge.

[0040] like Figure 1 As shown, in a preferred embodiment, based on the above method, the bottom filter tank 1 is further provided with symmetrically distributed support columns 4 fixedly connected to the outer wall, and support seats 5 fixedly connected to the outer wall of the support columns 4. The support columns 4 and support seats 5 provide stable support for the entire device, ensuring that the device will not shake or tip over during operation.

[0041] like Figure 2 As shown, in a preferred embodiment, based on the above method, the top filter barrel 3 is further provided with a uniformly distributed guide rod 9 fixedly connected to its top wall. A mounting plate 7 is slidably connected to the outer wall of the guide rod 9. An adjusting screw 10 is threadedly connected to the outer wall of the mounting plate 7, and the adjusting screw 10 is rotatably connected to the top filter barrel 3. The guide rod 9 on the top wall of the top filter barrel 3 serves as a guide, allowing the mounting plate 7 to slide stably along the guide rod 9. The height of the mounting plate 7 can be adjusted by adjusting the screw 10, thereby adjusting the position of the drive motor 8 and the hexagonal drive column 30 to better drive the filter plate 27 to rotate.

[0042] like Figure 1-3 As shown, in a preferred embodiment, based on the above method, a drive motor 8 is fixedly connected to the top wall of the mounting plate 7, a hexagonal drive column 30 is fixedly connected to the output end of the drive motor 8, and the hexagonal drive column 30 is rotatably connected to the top filter barrel 3, and the hexagonal drive column 30 is slidably connected to the hexagonal linkage block 29.

[0043] Specifically, when using the oil filtration device for the extruder gearbox: when the filter plate 27 needs to be replaced, pull the drawer 15 by the handle 16, causing it to slide against the outer wall of the outer square chamber 2. The movement of the drawer 15 moves the adaptive lifting plate 24 and the bottom positioning plate 25. Due to the action of the strong spring 26, when the filter plate 27 is squeezed by the top positioning plate 23, its position can be adaptively adjusted by the bottom positioning plate 25. When the distance between the bottom positioning plate 25 and the top positioning plate 23 is appropriate, the clamping plate 28 along with the filter plate 27 can be removed from between them, and then a filter plate 27 with a different pore size can be replaced. Then, it is installed back in its original position, which realizes the easy disassembly and replacement of filter plate 27, which facilitates later maintenance and the replacement of filter plate 27 with appropriate filter plates 27 for different densities of oil. When the drive motor 8 starts, the hexagonal drive column 30 at its output end rotates. Since both the hexagonal drive column 30 and the hexagonal linkage block 29 are hexagonal structures, they drive the filter plate 27 to rotate. When the filter plate 27 rotates, the scraper 19 that abuts against its outer wall will clean the surface of the filter plate 27 and scrape off the oil and other impurities on the filter plate 27. The scraper 19 slides on the fixed sleeve 18 through the cross-shaped locking block 22, which facilitates the later replacement and maintenance of the scraper 19.

[0044] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
