[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] like Figures 1 to 6 As shown, a purification device for lubricating oil preparation includes a purification machine body 1 and a heating structure 2 connected to the top of the purification machine body 1. A filter box 3 is fixedly connected to the top of the heating structure 2, and the bottom of the filter box 3 is connected to the heating structure 2. A multi-stage filtration structure is connected inside the filter box 3. The multi-stage filtration structure includes a coarse filter plate 8, a medium filter plate 9, and a fine filter plate 10. The coarse filter plate 8, the medium filter plate 9, and the fine filter plate 10 are inclined.

[0025] like Figure 1 As shown, the purification device for lubricating oil preparation in this utility model is structurally similar to existing lubricating oil production purification devices. For example, patent publication number CN217988977U discloses a lubricating oil production purification device. The main improvement of this utility model is that it enables the lubricating oil to have an impurity filtration function before purification; Figures 1 to 6 As shown, in the present invention, the purification device for lubricating oil preparation involves putting waste oil raw material into the filter box 3. The oil will pass through the coarse filter plate 8, the medium filter plate 9, and the fine filter plate 10. The three filter plates with different mesh sizes will filter the oil layer by layer, so that there are no impurities in the oil entering the heating structure 2, thereby improving the quality of the purified oil. In addition, the three filter plates are set at an angle, which can guide impurities to a lower position, thereby increasing the service life of the three filter plates, reducing the frequency of cleaning, and ensuring that filtration is not obstructed.

[0026] like Figure 1 and Figure 2 As shown, the top of the filter box 3 is connected to a feed component, which includes a cover plate 5. A feed inlet 6 that communicates with the filter box 3 is fixedly installed on one side of the top of the cover plate 5.

[0027] Specifically, when the oil is poured in, it can enter the filter box 3 through the inlet 6. The cover plate 5 can ensure that the top of the filter box 3 is covered, and the inlet 6 is located at the high point of the inclined three-layer filter plate, ensuring that impurities are smoothly guided to the lower position.

[0028] like Figure 2 , Figure 3 and Figure 5 As shown, the filter box 3 is connected to an inner box 12. The coarse filter plate 8, the medium filter plate 9 and the fine filter plate 10 are fixedly connected to the inner wall of the inner box 12. The top of the inner box 12 is fixedly connected to an overlap 19. The top surface of the filter box 3 is provided with an embedding groove 17 corresponding to the overlap 19. The bottom surface of the inner box 12 is open and connected to the heating structure 2.

[0029] Specifically, in order to facilitate the removal and cleaning of the coarse filter plate 8, the medium filter plate 9 and the fine filter plate 10, the inner box 12 can be removed from the filter box 3, so that the inner box 12 and the three filter plates can be removed from the filter box 3. When the inner box 12 is in normal use, the overlap 19 will be placed in the embedding groove 17 of the filter box 3 to ensure that the inner box 12 will not fall out of the filter box 3.

[0030] like Figure 2 and Figure 3 As shown, the inner box 12 has a sludge outlet 20 on one side, and the filter box 3 has a side opening 18 connected to the sludge outlet 20 on one side. The outer wall of the side opening 18 is connected to the collection box 4, and the inner wall of the collection box 4 has three openings 11.

[0031] Specifically, when impurities are guided from a high place to a low place, they will enter the collection box 4 through the opening 11, which makes it easier for the impurities to be collected by the collection box 4.

[0032] like Figure 6 As shown, outer plates 16 are fixedly connected to both sides of the outer wall of the collection box 4. The outer plates 16 are attached to the outer wall of the filter box 3. Bolts 21 are threadedly connected to the outer wall of the outer plates 16. The bolts 21 pass through the outer plates 16 and are connected to the filter box 3.

[0033] Specifically, in order to facilitate the removal of the collection box 4, the bolts 21 on the outer plate 16 can be separated from the filter box 3, which makes it easier to remove the collection box 4.

[0034] like Figure 2 and Figure 4 As shown, scrapers 14 are slidably connected to the top surfaces of the coarse filter plate 8, the medium filter plate 9, and the fine filter plate 10. Three multi-stage electric actuators 15 are fixedly installed on the outer wall of the filter box 3. The multi-stage electric actuators 15 pass through the filter box 3 and are fixedly connected to the back of the scrapers 14.

[0035] Specifically, in order to improve the filtration effect of the coarse filter plate 8, the medium filter plate 9, and the fine filter plate 10, the multi-stage electric actuator 15 can be activated. Its output end will drive the scraper 14 to scrape on the inclined filter plate, pushing the impurities into the collection box 4. In this way, the filtration effect of the three filter plates is further extended.

[0036] like Figure 1 and Figure 3 As shown, a mounting box 7 is detachably connected to the outer wall of the filter box 3, and the mounting box 7 is located on the outside of the three multi-stage electric actuators 15. The mounting box 7 is designed to protect the three multi-stage electric actuators 15.

[0037] like Figure 3 and Figure 5 As shown, handles 13 are fixedly connected to both sides of the inner wall of the inner box 12. The handles 13 are provided to facilitate lifting the inner box 12.

[0038] In the above structure, the multi-stage electric actuator 15 is a mature existing technology, so it will not be described in detail here.

[0039] Although the present invention 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
