Description

Technical Field

[0001] This utility model relates to the field of lubricating oil production technology, and specifically discloses a filtration device for lubricating oil production. Background Technology

[0002] Lubricating oil is a liquid lubricant used in various types of machinery to reduce friction and protect the machinery and machined parts. Its main functions include lubrication, cooling, rust prevention, cleaning, sealing, and buffering. Lubricating oil additives are one or more compounds added to the lubricant to give it new properties or improve existing properties. During the production of lubricating oil, it contains a large amount of residue, which needs to be filtered using filtration equipment.

[0003] Existing filtration equipment for lubricating oil production is inconvenient to clean the impurities trapped by the filter, and most of them use static filtration, which results in uneven distribution of oil on the filter surface, making the filter structure prone to local blockage. This can easily cause excessive local load on the filter medium and affect the filtration efficiency. Therefore, a new filtration equipment for lubricating oil production is needed to solve this problem. Utility Model Content

[0004] This utility model proposes a filtration device for lubricating oil production. The first stage of coarse filtration is achieved by a fixed, tilted filter cylinder. Large particles of impurities are automatically slid to the bottom by gravity, effectively intercepting large particles of impurities and using gravity for self-cleaning. The laterally moving liquid collection cylinder can evenly disperse the lubricating oil to the surface of the filter frame, avoiding local blockage and improving the efficiency of the second stage of filtration.

[0005] This utility model is implemented as follows: a filtration device for lubricating oil production includes a main pipeline, and a first filtration mechanism is provided inside the main pipeline.

[0006] The first filtration mechanism includes a vertical pipe connected to the middle of the bottom of the outer wall of the main pipe, a filter cylinder installed inside the vertical pipe with an open upper end, the top of the filter cylinder having an inclined structure, and the higher end of the filter cylinder being fixedly connected to the inner wall of the main pipe, a connecting pipe connected to the right side of the main pipe, and the main pipe being connected to a second filtration mechanism through the connecting pipe.

[0007] The second filtration mechanism includes a liquid collection chamber located below the connecting pipe, a filter frame attached to the inside of the liquid collection chamber, a top frame fixedly connected to the top of the liquid collection chamber via a connecting column, a threaded rod rotatably connected to the inside of the top frame, a motor installed on the outer wall of the top frame and whose output end is fixedly connected to the threaded rod, a slide connected to the outer wall of the threaded rod, a liquid collection cylinder installed at the bottom of the slide, and multiple liquid outlets connected to the bottom of the liquid collection cylinder. The liquid collection cylinder and the connecting pipe are connected by a flexible hose.

[0008] As a preferred embodiment of the filtration equipment for lubricating oil production according to this utility model, the mesh diameter of the filter cylinder is larger than the mesh diameter of the filter frame.

[0009] As a preferred embodiment of the filtration equipment for lubricating oil production according to this utility model, the bottom end of the vertical pipe is detachably connected to a baffle for sealing the bottom opening of the filter cylinder by bolts.

[0010] As a preferred embodiment of the filtration equipment for lubricating oil production according to this utility model, the outer wall of the liquid collection chamber is connected to a drain pipe located below the filter frame.

[0011] As a preferred embodiment of the filtration equipment for lubricating oil production according to this utility model, the top frame is internally fixedly connected with a guide rod that is slidably connected to the slide.

[0012] As a preferred embodiment of the filtration equipment for lubricating oil production according to this utility model, a controller is installed on the outer wall of the liquid collection chamber, and the motor is electrically connected to the controller.

[0013] The beneficial effects of this utility model are:

[0014] 1. After the lubricating oil enters from the main pipeline, it first undergoes coarse filtration through the inclined filter cylinder. Large particles of impurities are trapped and slide down to the bottom of the filter cylinder under gravity. The filtered oil flows into the flexible hose through the connecting pipe, thus achieving the primary coarse filtration stage.

[0015] 2. The screw rod is driven by a motor to rotate, which causes the slide to move the liquid collection cylinder laterally along the screw rod, and the oil is evenly sprayed onto the surface of the filter frame from the liquid outlet for fine filtration.

[0016] In summary, the first stage of coarse filtration is achieved by using a fixed, tilted filter cartridge. Large particles of impurities are automatically slid to the bottom by gravity, effectively intercepting large particles of impurities and using gravity for self-cleaning. The laterally moving liquid collection cartridge can evenly distribute lubricating oil to the surface of the filter frame, avoiding local blockage and improving the efficiency of the second stage of filtration.

[0022] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

The liquid collection cylinder 307 and the connecting pipe 202 are connected by a flexible hose 309.

[0026] In this embodiment: after the lubricating oil enters from the main pipe 1, it first undergoes coarse filtration through the inclined filter cylinder 2. Large particles of impurities are intercepted and slide down to the bottom of the filter cylinder 2 under the action of gravity. The filtered oil flows into the flexible hose 309 through the connecting pipe 202, thus achieving the primary coarse filtration stage.

[0027] The motor 305 drives the threaded rod 304 to rotate, causing the slide 306 to move the liquid collection cylinder 307 laterally along the threaded rod 304, and the oil is evenly sprayed from the liquid outlet 308 onto the surface of the filter frame 301 for fine filtration.

[0028] The first stage of coarse filtration is achieved by tilting and fixing the filter cylinder 2. Large particles of impurities are automatically slid to the bottom by gravity, effectively intercepting large particles of impurities and using gravity for self-cleaning. The horizontally moving liquid collection cylinder 307 can evenly distribute the lubricating oil to the surface of the filter frame 301, avoiding local blockage and improving the efficiency of the second stage of filtration.

[0029] As a technical optimization of this utility model, the mesh diameter of the filter cylinder 2 is larger than the mesh diameter of the filter frame 301.

[0030] In this embodiment, since the mesh diameter of the filter cylinder 2 is larger than that of the filter frame 301, impurities of all sizes in the lubricating oil can be intercepted and filtered.

[0031] As a technical optimization of this utility model, the bottom end of the vertical tube 101 is detachably connected to a baffle 201 for sealing the bottom opening of the filter cylinder 2 by bolts.

[0032] In this embodiment: Loosening the bolts and removing the baffle 201 allows for the cleaning of impurities trapped inside the filter cartridge 2.

[0033] As a technical optimization of this utility model, the outer wall of the liquid collection chamber 3 is connected to the drain pipe 302 located below the filter frame 301.

[0036] In this embodiment, the slide 306 can be moved stably by the guide rod.

[0037] As a technical optimization of this utility model, a controller is installed on the outer wall of the liquid collection chamber 3, and the motor 305 is electrically connected to the controller.

[0038] In this embodiment, the motor 305 can be controlled to work via a controller.

[0039] The working principle and usage process of this utility model are as follows: The main pipeline is connected to the lubricating oil inlet pipe. After the lubricating oil enters from the main pipeline 1, it first undergoes coarse filtration through the inclined filter cylinder 2. Large particles of impurities are intercepted and slide down to the bottom of the filter cylinder 2 under the action of gravity. The filtered oil flows into the flexible hose 309 through the connecting pipe 202. Then, the motor 305 drives the threaded rod 304 to rotate, causing the slide 306 to drive the liquid collection cylinder 307 to move laterally along the threaded rod 304. The oil is evenly sprayed onto the surface of the filter frame 301 from the liquid outlet 308 for fine filtration. The filtered oil is discharged through the drain pipe 302. Impurities are intercepted on the filter frame 301. By removing the filter frame 301 from the liquid collection chamber 3, the impurities inside the filter frame 301 can be cleaned.
