Technical Field
[0001] This utility model relates to the field of filtration device technology, and more specifically, to a waste lubricating oil filtration device. Background Technology
[0002] Lubricating oil is a liquid or semi-solid lubricant used in various mechanical equipment to reduce frictional resistance, alleviate wear, and provide auxiliary cooling, rust prevention, cleaning, sealing, and buffering functions. However, waste lubricating oil from oil fields typically contains a large amount of impurities, including metal particles such as iron filings, silt, oxidation products, and moisture. Traditional filtration devices often experience filter clogging due to these impurities, requiring frequent cleaning or replacement. However, disassembling and assembling traditional filters is inconvenient, and existing easy-to-disassemble filters offer limited filtration methods, failing to meet the demands for efficient recycling of waste lubricating oil from oil fields.
[0003] Therefore, it is necessary to design a lubricating oil filtration device that is easy to clean and maintain. Utility Model Content

[0027] Example
[0028] The present invention will be further described in detail below with reference to the accompanying drawings.
[0029] This application provides a waste lubricating oil filtration device, including a housing 1, a cover 2, a door 7, a filter assembly 5, a centrifugal assembly 9, a guide plate 10, an inlet, and an outlet 8; the cover 2 and the door 7 are hinged to the housing 1, the filter assembly 5 is located at the top of the inner cavity of the housing 1, the centrifugal assembly 9 is located at the bottom of the inner cavity of the housing 1, the guide plate 10 is located in the middle of the inner cavity of the housing 1 and is connected to the centrifugal assembly 9, the inlet is located at the top of the cover 2, and the outlet 8 is located at the bottom of the housing 1;
[0030] The inner wall of the housing 1 is fixedly connected to a fixing block 6, and the fixing block 6 is evenly distributed along the inner wall of the housing 1.
[0031] The filter assembly 5 includes a support plate 13, a filter screen, and a pressure plate 14. The support plate 13 abuts against the fixing block 6, the pressure plate 14 is hinged to the support plate 13, and the filter screen is laid between the support plate 13 and the pressure plate 14.
[0032] The centrifugal assembly 9 includes a drum, a drive motor 12, and a fixing pin 11. The drum is rotatably connected to the drive motor 12 via the fixing pin 11.
[0033] The drive motor 12 drives the drum to rotate via belt drive. The bottom shaft of the drum is fixed to the drive shaft by the fixing pin 11. When the drum needs to be cleaned, the drum can be removed simply by removing the fixing pin 11, without any other additional disassembly or assembly.
[0034] The structure of the roller is as follows Figure 4 As shown, the outer wall of the drum is evenly distributed with filter holes. The top of the drum is rotatably connected to the bottom of the guide plate. The structure of the guide plate 10 is similar to a funnel, which can isolate the inner cavity of the shell 1 into two parts, namely the filter assembly 5 and the centrifugal assembly 9, to prevent uncentrifuged waste lubricating oil from entering the discharge port 8. Its function also includes introducing the waste lubricating oil filtered by the filter assembly 5 into the drum. When the drum centrifuges and filters, the waste lubricating oil flows out from the filter holes of the drum and enters the discharge port 8 at the bottom of the shell 1, thus completing the filtration of waste lubricating oil.
[0035] It should be noted that the pore size of the roller filter shown in the figure is only for illustrative purposes. The pore size of the roller should be smaller than that of the filter screen to achieve a better filtration effect.
[0036] Furthermore, both the bearing plate 13 and the pressure plate 14 are mesh plates.
[0037] In this embodiment, as Figure 3 As shown, both the support plate 13 and the pressure plate 14 are devices for fixing the filter screen. The support plate 13 is used to support the filter screen and provide support for its installation. The pressure plate 14 is used to fix the filter screen to prevent it from shifting during filtration. The aperture of the support plate 13 and the pressure plate 14 is much larger than that of the filter screen so that the waste lubricating oil to be filtered can flow out of the filter screen along a predetermined path, ensuring the filtration effect. When the filter screen needs to be cleaned, the filter screen can be removed simply by opening the hinged pressure plate 14 without any additional disassembly or assembly work.
[0038] It should be noted that, Figure 3 The mesh size of the support plate 13 and the pressure plate 14 is only for illustrative purposes. The mesh size of the support plate 13 and the pressure plate 14 should be set according to the actual usage requirements. Alternatively, the support plate 13 and the pressure plate 14 can be used directly as filter plates, but in this case, the mesh diameter of the support plate 13 and the pressure plate 14 should be adjusted according to the filtration requirements.
[0039] Furthermore, the support plate 13 is provided with limiting bosses on all four sides.
[0040] In this embodiment, as Figure 3 As shown, the limiting boss is a single-sided arc-shaped boss, so as to reintroduce the waste lubricating oil flowing into the edge of the support plate 13 into the filter screen, and at the same time limit the filter residue, so that the support plate 13 can act as a residue collection box to prevent the filter residue from falling off the plate surface during the removal of the entire filter assembly 5.
[0041] Furthermore, the feed inlet is equipped with a solenoid valve 3.
[0042] Solenoid valve 3 can achieve periodic feeding according to a preset program.
[0043] Furthermore, a spring post is provided on the upper surface of the fixing block 6, and a limiting post adapted to the spring post is provided on the lower surface of the bearing plate 13.
[0044] like Figure 2 , Figure 3 As shown, the limiting column and the spring column work together to cause the filter assembly to vibrate rhythmically up and down under the constraint and guidance of the spring column and the limiting column during periodic feeding. This vibration is similar to the motion mode of a vibrating screen, which allows the filter medium to continuously adjust its filtration state during vibration, effectively preventing clogging and improving filtration efficiency. At the same time, vibration helps to evenly distribute the material on the filter surface, enhancing the filtration effect and thus achieving better separation results.
[0045] Furthermore, a guide slope is provided at the bottom of the inner wall of the door body 7 to prevent lubricating oil from overflowing.
[0046] On the one hand, the guide ramp is designed to effectively prevent lubricating oil from accumulating and overflowing at the bottom of the gate 7, ensuring a clean and safe operating environment. On the other hand, in actual operation, the guide ramp can guide the lubricating oil to flow back in an orderly manner to the discharge port 8 at the bottom of the housing 1. At the same time, the design of the guide ramp reduces the residue of waste lubricating oil on the inner wall of the gate 7, which helps to extend the service life of the equipment and improve its reliability and maintenance efficiency.
[0047] Furthermore, sealing rubber gaskets are provided along the edges of the cover 2, the door 7, and the support plate 13.
[0048] The sealing rubber gaskets of each component enhance sealing performance, reduce the risk of leakage, improve the overall performance and environmental friendliness of the equipment, and meet the needs of efficient recycling of waste lubricating oil in oil fields.
[0049] When this device is running, the door is closed. After the device has finished running, the door can be opened for cleaning and maintenance. Compared with the integrated filter device in the prior art, this device uses filter component 5 and centrifugal component 9 to filter at the same time, which ensures the filtration effect and makes cleaning and maintenance more convenient.
[0050] The above description is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above through embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
