[0025] The present invention is further described in detail below with reference to the embodiments.
[0026] Specific embodiments of the lubricating oil purification device provided by the utility model:
[0027] See also Figure 1-6 The lubricating oil purification device includes a plurality of filter plates 1, a plurality of magnetic plates 2, and a housing 3. The filter plates 1 and magnetic plates 2 are alternately arranged to form a cylindrical structure, with adjacent filter plates 1 and magnetic plates 2 connected without gaps between them. In this embodiment, the filter plates 1 and magnetic plates 2 are both curved, making the cylindrical structure a circular cylinder. The filter plates 1 are evenly distributed with filter holes to allow the lubricating oil to pass through and to block impurities. The magnetic plates 2 are permanent magnets that are used to absorb metal impurities in the lubricating oil.
[0028] The outer shell 3 wraps the cylindrical structure and supports the upper and lower ends of the cylindrical structure. The outer shell 3 is disc-shaped and has an opening in the center of the upper side. The opening corresponds to the inner side of the upper tube mouth of the cylindrical structure. The cylindrical structure is located inside the center of the outer shell 3.
[0029] An oil outlet 5 is connected to the outer ring side of the shell 3. An annular cavity is provided between the outer side of the cylindrical structure and the shell 3 and is filled with a desiccant 4. The oil outlet 5 is connected to the cavity where the desiccant 4 is located. In this embodiment, the desiccant 4 is preferably made of silica gel particles, which can absorb moisture in the lubricating oil and have strong stability.
[0030] The upper side of the shell 3 is provided with an oil inlet 7 corresponding to the opening on the upper side of the shell 3, and the oil inlet 7 is in communication with the inner side of the cylindrical structure; the lubricating oil enters the inner side of the cylindrical structure from the oil inlet 7, passes through the filter plate 1, and the impurities are left in the inner side of the filter plate 1, and the inner side of the magnetic plate 2 alternately arranged between the filter plate 1 can adsorb the metal impurities in the lubricating oil; the lubricating oil after filtering the impurities is in full contact with the silica gel particles in the cavity, and after removing the moisture, it is discharged from the oil outlet 5.
[0031] The oil outlet 5 is provided with a filter screen 6 for blocking the desiccant 4, the mesh aperture of the filter screen 6 is smaller than the particle size of the silica gel particles, and larger than the aperture of the filter hole on the filter plate 1; it can not only block the silica gel particles from flowing with the lubricating oil, but also not affect the circulation of the lubricating oil. The oil outlet 5 is provided with a flange, which is convenient for communicating with the external lubricating oil conveying pipeline through bolts. The conveying of the lubricating oil can rely on the external power of the lubricating oil conveying site.
[0032] In this embodiment, the lower side of the shell 3 is also provided with an opening corresponding to the inner side of the lower cylinder of the cylindrical structure, and the lower side of the shell 3 is connected with a sewage outlet 8, and the sewage outlet 8 corresponds to the opening on the lower side of the shell 3, so that the sewage outlet 8 is in communication with the inner side of the cylindrical structure; in this way, the oil inlet 7 and the sewage outlet 8 are respectively located at the two ends of the outer side of the cylindrical structure, i.e. the upper and lower ends of the outer side.
[0033] The sewage outlet 8 is connected with a sewage collecting tank 9, and the impurities accumulated in the inner side of the cylindrical structure fall down and are collected in the sewage collecting tank 9. In this embodiment, the sewage outlet 8 and the inlet of the sewage collecting tank 9 are both provided with flanges and connected by bolts. The bolts can be disassembled to realize the disassembly of the sewage collecting tank 9, and the sewage collecting tank 9 can be cleaned regularly. Because the sewage collecting tank 9 can collect and contain a large amount of impurities, the disassembly and cleaning period is greatly extended.
[0034] In this embodiment, the oil inlet 7 is provided with a flange, and the oil inlet 7 is connected with an oil inlet pipe 14 through the flange and the bolts, and the oil inlet pipe 14 is located on the upper side of the oil inlet 7. The lubricating oil enters the inner side of the cylindrical structure from the oil inlet pipe 14 and the oil inlet 7 under the conveying of the external power, and then passes through the filter plate 1 of the cylindrical structure.
[0035] A vertical central shaft 10 is installed in the central rotation of the cylindrical structure. In this embodiment, brackets 11 are provided on the inner sides of the oil inlet 7 and the sewage outlet 8 to support the rotation of the central shaft 10. The brackets 11 realize the rotation support and vertical limitation of the central shaft 10, such as a bearing supporting the central shaft 10 is provided on the bracket 11, and a shoulder that cooperates with the bearing is provided on the central shaft 10; the upper end of the central shaft 10 extends into the oil inlet pipe 14, and a blade 12 is provided on the outer side of the end. The blades 12 are vertically arranged into several groups, each group is at the same height, and are evenly distributed on the outer side of the central shaft 10; a spiral blade 13 is connected to the outer side of the central shaft 10 in the cylindrical structure. In this embodiment, a number of connecting rods are connected between the spiral blade 13 and the central shaft 10, and the outer edge of the spiral blade 13 is located on the inner side of the cylindrical structure; in this embodiment, the spiral blade 13 and the filter plate 1 are preferably made of non-ferrous metal.
[0036] Lubricating oil flows in oil inlet pipe 14, driving blades 12 to rotate. Blades 12 drive central shaft 10 and spiral blades 13 to rotate. Spiral blades 13 scrape impurities from the inside of the cylindrical structure. Specifically, they scrape impurities accumulated on the inside of filter plate 1 and metal impurities adsorbed on the inside of magnetic plate 2, causing the impurities to move downward and fall into dirt collection box 9 for collection. Spiral blades 13 continuously clean impurities from the inside of the cylindrical structure, maintaining a high pass rate for filter plate 1 and a sufficient adsorption surface for magnetic plate 2.
[0037] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments without inventive effort, or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
