[0002] The main functions of lubricating oil include lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. It can form an oil film between two relatively moving objects to reduce friction and wear, thereby extending the service life of mechanical equipment. At the same time, lubricating oil can also take away the heat generated by friction, play a cooling role, and prevent metal parts from rusting and corrosion;

[0003] Lubricating oil base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil, such as viscosity, pour point, flash point, oxidation stability, etc. At present, when enterprises produce lubricating oil, they need to filter the lubricating oil base oil to remove impurities mixed in the lubricating oil. However, since lubricating oil is relatively viscous, it is easy to adhere to the filter net, thereby affecting the filtration efficiency of the lubricating oil.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0024] See also Figures 1 to 5 The embodiment of the utility model provides a filtering device for lubricating oil base oil processing, and the filtering device for lubricating oil base oil processing includes a filter disc 1, an inner ring 3 and an eccentric pressing plate 4.

[0025] In the embodiments of the present invention, please refer to Figures 1 to 5 The lower disk surface of the filter disc 1 is fixedly mounted with a carrying box 2 for supporting the filter disc 1, the top of the filter disc 1 is mounted with a feed pipe 11, and the carrying box 2 is mounted with a discharge valve 21, and the disk surface of the filter disc 1 corresponding to the carrying box 2 is provided with a plurality of evenly distributed filter holes 2a, and the filter disc 1 is mounted with an inner ring 3 which is rotatably connected and coaxially arranged with the filter disc 1, specifically, a servo motor 6 is fixedly mounted on the back of the filter disc 1 through a frame, the output end of the servo motor 6 extends into the filter disc 1 and is fixedly mounted with a rotating shaft 61, and the rotating shaft 61 is fixedly connected with the mounting bracket 31 on the inner ring 3;

[0026] An oil cavity for the flow of lubricating base oil is reserved between the outer ring surface of the inner ring 3 and the inner disk wall of the filter disk 1, and a plurality of eccentric pressing plates 4 are fixedly embedded on the outer ring surface of the inner ring 3, and the gap between the outer plate wall of the eccentric pressing plate 4 and the inner disk wall of the filter disk 1 increases gradually as the filter disk 1 rotates counterclockwise.

[0027] It should be noted that: the lubricating base oil is discharged from the feed pipe 11 into the oil cavity between the filter disc 1 and the inner ring 3, and the lubricating base oil flows down along the oil cavity to both sides and gathers at the bottom of the oil cavity, and the lubricating base oil gathered at the bottom of the oil cavity is filtered through the filter hole 2a, and the filtered lubricating base oil falls into the carrying box 2 for storage;

[0028] At the same time, the servo motor 6 is turned on to drive the inner ring 3 to rotate counterclockwise. Since the gap between the outer plate wall of the eccentric pressing plate 4 and the inner plate wall of the filter disc 1 increases with the counterclockwise rotation direction of the filter disc 1, the eccentric pressing plate 4 can gradually squeeze the lubricating base oil gathered at the bottom of the oil chamber, thereby accelerating the filtering rate of the lubricating base oil.

[0029] Wherein, a transparent end cover 7 is provided on the front end surface of the filter disc 1 to facilitate observation of the filtering condition of the lubricating base oil in the filter disc 1 .

[0030] In the embodiments of the present invention, please refer to Figures 1 to 5 A hollow cavity is provided in the eccentric pressing plate 4, and a scraper assembly 5 is installed in the hollow cavity. The scraper assembly 5 includes a hydraulic cylinder 51, and the hydraulic cylinder 51 is fixedly installed in the hollow cavity. A middle bracket 52 is fixedly installed at the output end of the hydraulic cylinder 51, and a fixedly connected scraper plate 53 is installed on the middle bracket 52. The plate head of the scraper plate 53 is inserted into the opening 4a provided in the eccentric pressing plate 4 and seals the opening 4a, and the plate head of the scraper plate 53 is provided with a tough surface 531, and a slag discharge port 1a is provided on the side of the filter disc 1 deviating from the filter hole 2a, and a rotatably connected arc-shaped sealing door 12 is installed on the slag discharge port 1a.

[0031] It should be noted that: when the lubricating oil base oil is filtered, the hydraulic cylinder 51 is turned on so that the hydraulic cylinder 51 pushes the scraper plate 53 out of the eccentric pressing plate 4 until the tough surface 531 of the eccentric pressing plate 4 abuts against the inner disk wall of the filter disk 1. At this time, the servo motor 6 is turned on to drive the inner ring 3 to rotate, so that the scraper plate 53 can scrape off the filter residue on the filter hole 2a. Subsequently, the arc-shaped sealing door 12 is opened to allow the scraper plate 53 to discharge the filter residue from the discharge port 1a, thereby avoiding the hidden danger of blockage of the filter hole 2a.

[0032] The working principle of the filtering device for lubricating oil base oil processing provided by the utility model is as follows:

[0033] The lubricating oil base oil is discharged from the feed pipe 11 into the oil chamber between the filter disc 1 and the inner ring 3, and the lubricating oil base oil flows down along the oil chamber to both sides and gathers at the bottom of the oil chamber, and the lubricating oil base oil gathered at the bottom of the oil chamber is filtered through the filter hole 2a, and the filtered lubricating oil base oil falls into the carrying box 2 for storage; at the same time, the servo motor 6 is turned on to drive the inner ring 3 to rotate counterclockwise, and because the outer plate wall of the eccentric pressing plate 4 increases the gap with the inner plate wall of the filter disc 1 as the filter disc 1 rotates counterclockwise, the eccentric pressing plate 4 can collect the lubricating oil base oil gathered at the bottom of the oil chamber. The lubricating base oil is gradually squeezed, thereby accelerating the filtration rate of the lubricating base oil. When the lubricating base oil is filtered, the hydraulic cylinder 51 is turned on so that the hydraulic cylinder 51 pushes the scraper plate 53 out of the eccentric pressing plate 4 until the tough surface 531 of the eccentric pressing plate 4 abuts against the inner wall of the filter disc 1. At this time, the servo motor 6 is turned on to drive the inner ring 3 to rotate, so that the scraper plate 53 can scrape off the filter residue on the filter hole 2a. Subsequently, the arc-shaped sealing door 12 is opened to allow the scraper plate 53 to discharge the filter residue from the discharge port 1a, thereby avoiding the hidden danger of clogging of the filter hole 2a.

[0034] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0035] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
