Description

Technical Field

[0001] The present invention relates to the field of lubricating oil stations, in particular to a lubricating oil station with a clean oil delivery structure. Background Art

[0002] The working principle of the lubricating oil station is to extract the lubricating oil from the oil tank through the oil pump and transport it to the processing equipment that needs lubrication through the pipeline, so as to ensure that the parts in the processing equipment remain lubricated and reduce the wear of parts during the processing. When lubricating the processing equipment, the lubricating oil will produce some solid impurities, so the lubricating oil needs to be filtered when the lubricating oil station is working to ensure the lubrication effect.

[0003] The patent document with publication number CN218530047U discloses a lubricating oil station with clean oil delivery and an oil purification device, including a device body and a fixed cylinder. The fixed cylinder is fixedly mounted on the base of the device body, and the interior of the fixed cylinder is communicated with the interior of the oil inlet pipe of the device body.

[0004] In the prior art, when filtering lubricating oil, the lubricating oil is usually transported to the inside of a vertically arranged filter cartridge, and impurities generated by the filtration are stored at the bottom of the filter cartridge. When the lubricating oil enters the filter cartridge, gravity causes the lubricating oil to flow directly to the bottom of the filter cartridge and is filtered through the filter holes at the bottom of the filter cartridge, resulting in a single filtration position. When impurities accumulate at the bottom of the filter cartridge, the lubricating oil needs to pass through the surface of the impurities and then be filtered through the filter holes. As impurities accumulate, the filtration speed of the lubricating oil gradually decreases, affecting the filtration efficiency of the lubricating oil. Summary of the Invention

[0024] As a further embodiment of the present invention, the impurity pushing mechanism includes a spiral blade 23, which is fixedly connected to the rotating shaft 15, and the spiral blade 23 is in contact with the inner wall of the filter ring 10; during operation, when the rotating shaft 15 rotates and drives the filter ring 10 to rotate in the opposite direction, the spiral blade 23 rotates in the same direction as the rotating shaft 15, so that the spiral blade 23 rotates in the opposite direction of the filter ring 10 inside the filter ring 10, and the impurities inside the filter ring 10 are spirally pushed toward the end of the filter ring 10 away from the first oil return pipe 5 through the rotation of the spiral blade 23, and the impurity pushing efficiency is improved during the reverse rotation of the filter ring 10 and the spiral blade 23.

[0025] As a further embodiment of the present invention, the impurity collecting mechanism includes a sealing baffle 24 and a rotating plate 25. The sealing baffle 24 is arranged inside the rotating ring 12. A plurality of plug pins 26 are fixedly connected to the inside of the circular groove 11 along the circumferential direction. The plug pins 26 are fixedly inserted on the sealing baffle 24. The rotating shaft 15 is rotatably connected to the axis of the sealing baffle 24. The sealing baffle 24 is located at the end of the sun gear 16 away from the sealing cover plate 9. The rotating plate 25 is fixedly connected to the rotating shaft 15 and is located at the end of the spiral blade 23 close to the sealing cover plate 9. A feed trough 27 is provided on the rotating plate 25. An impurity squeezing mechanism is connected between the rotating plate 25 and the sealing baffle 24. When working, the sealing baffle 24 is fixedly plugged by a plurality of plug pins 26 so that The sealing baffle 24 blocks the sun gear 16, the planetary gears 18 and the inner gear ring 17 at one end close to the filter ring 10 to prevent solid impurities from being pushed to the meshing position of the sun gear 16, the planetary gears 18 and the inner gear ring 17 and affecting the meshing. The rotating shaft 15 drives the spiral blade 23 and the rotating plate 25 to rotate synchronously during the rotation. When the spiral blade 23 rotates, the solid impurities are pushed axially along the inside of the filter ring 10, and when the feed groove 27 on the rotating plate 25 rotates to the bottom of the inside of the filter ring 10, the spiral blade 23 spirally pushes the impurities at the bottom of the inner wall of the filter ring 10, and when the feed groove 27 is connected to the bottom of the inner wall of the filter ring 10, the solid impurities are pushed along the feed groove 27 to between the rotating plate 25 and the sealing baffle 24.

[0026] As a further embodiment of the present invention, the impurity squeezing mechanism includes a squeezing plate 28, which is arranged between the rotating plate 25 and the sealing baffle 24. The rotating shaft 15 and the plug pin 26 are both slidably inserted on the squeezing plate 28. A guide ring 29 is fixedly connected to the rotating shaft 15. The surface of the guide ring 29 is provided with an inclined ring groove 30 (such as Figure 11As shown in FIG, the extrusion plate 28 is fixedly connected to one end of the sealing baffle 24 with a first L-shaped frame 31, and two limit pins 32 are fixedly connected to the first L-shaped frame 31, and the two limit pins 32 are slidably inserted with a second L-shaped frame 33, and the limit pins 32 are sleeved with a spring 34, and the spring 34 is fixedly connected between the second L-shaped frame 33 and one end of the corresponding limit pin 32, and the second L-shaped frame 33 is fixedly connected with a guide pin 35, and the bottom end of the guide pin 35 is provided with a ball groove 36, and the inside of the ball groove 36 is connected with a contact ball 37 in a rolling manner, and the contact ball 37 is located inside the inclined ring groove 30; when working, the rotating shaft 15 drives the spiral blade 2 3 rotates, and when the spiral blade 23 rotates, the solid impurities are pushed axially along the inside of the filter ring 10, and pushed along the feed groove 27 on the rotating plate 25 to between the rotating plate 25 and the extrusion plate 28. The guide ring 29 rotates along the rotating shaft 15, and guides the contact ball 37 through the inclined ring groove 30 on the guide ring 29, so that the extrusion plate 28 moves toward the rotating plate 25 along the sliding insertion point of the plug pin 26. When the feed groove 27 on the rotating plate 25 rotates to the upper part of the filter ring 10, the extrusion plate 28 and the rotating plate 25 move to the closest distance, and squeeze the solid impurities between the extrusion plate 28 and the rotating plate 25. Thus, the lubricating oil on the surface of the solid impurities is extruded and flows along the filter holes 1001 on the filter ring 10 to the communicating shell 7, reducing the adsorption residue of the lubricating oil on the surface of the solid impurities; in general, when the feed groove 27 on the rotating plate 25 rotates to the upper part of the filter ring 10, the squeezing plate 28 and the rotating plate 25 squeeze the solid impurities. When the feed groove 27 on the rotating plate 25 rotates to the lower part of the filter ring 10, the squeezing plate 28 and the rotating plate 25 move to the farthest distance, the feed groove 27 is connected to the bottom of the inner wall of the filter ring 10, so that the impurities filtered and precipitated on the filter ring 10 are discharged along the feed groove 27. The second L-shaped frame 33 moves along the sliding joint of the limit pin 32 when the extrusion plate 28 approaches the rotating plate 25 and extrude the solid impurities, thereby preventing the impurities between the extrusion plate 28 and the rotating plate 25 from being pushed out along the feed trough 27 during extrusion. As the solid impurities between the extrusion plate 28 and the rotating plate 25 gradually increase, the extrusion plate 28 approaches the rotating plate 25 and extrude the solid impurities. The second L-shaped frame 33 moves along the sliding joint of the limit pin 32 and squeezes the spring 34 to produce compression deformation, thereby elastically giving way between the extrusion plate 28 and the rotating plate 25, and rolling the contact ball 37 inside the inclined ring groove 30 through the contact ball 37, and rolling limiting the contact ball 37 through the ball groove 36, thereby reducing the contact friction during the guide limiting and improving the stability during the movement.

[0027] As a further embodiment of the present invention, a collecting box 42 is provided between the rotating plate 25 and the squeezing plate 28. The collecting box 42 is fixedly connected to the corresponding two plug pins 26. A plurality of filtrate holes 4201 are provided at the bottom of the collecting box 42. A scraper 44 (such as Figure 12As shown in the figure, the scraper 44 is in contact with the rotating plate 25, and the extrusion plate 28 is provided with a matching groove 43 that is compatible with the collecting box 42 and the scraper 44. During operation, when the extrusion plate 28 approaches the rotating plate 25 and squeezes the solid impurities, the collecting box 42 and the scraper 44 both enter the inside of the matching groove 43 to prevent the movement of the extrusion plate 28 from being affected. After the extrusion plate 28 approaches the rotating plate 25 and squeezes the solid impurities, some of the solid impurities are squeezed and adhered to the surface of the rotating plate 25, and the rotating shaft 15 drives the rotating plate 25 to rotate. When the filter ring 10 is turned on, the solid impurities adhering to the rotating plate 25 rotate synchronously with the rotating plate 25 and move to the top of the collecting box 42. The scraper 44 on one side of the collecting box 42 scrapes the solid impurities adhering to the rotating plate 25, causing the solid impurities to fall into the inside of the collecting box 42. The solid impurities are located above the inside of the filter ring 10 and maintain a certain height difference with the lubricating oil being transported and filtered, and are isolated to prevent the solid impurities from continuing to absorb the lubricating oil, and the lubricating oil on the surface of the solid impurities is continued to be filtered out through the filtrate hole 4201 at the bottom of the collecting box 42.

[0028] As a further embodiment of the present invention, the positioning mechanism includes two first fixing blocks 38 and two second fixing blocks 39. The two first fixing blocks 38 are fixedly connected to the surface of the horizontal cylinder 6 (such as Figure 2 As shown), the two second fixing blocks 39 are fixedly connected to the surface of the sealing cover plate 9 along the circumferential direction, and the corresponding first fixing blocks 38 and second fixing blocks 39 are threadedly connected with second bolts 40, and the sealing cover plate 9 is fixedly connected to one end close to the horizontal cylinder 6 with a sealing rubber ring 41; during operation, the corresponding first fixing blocks 38 and second fixing blocks 39 are threadedly fixed by the second bolts 40, so as to fix the sealing cover plate 9 at the opening of the horizontal cylinder 6, and the sealing rubber ring 41 is provided between the horizontal cylinder 6 and the sealing cover plate 9 to ensure the sealing performance of the sealing cover plate 9. By removing the second bolts 40, the sealing cover plate 9 can be dropped from one end of the horizontal cylinder 6, and the filter ring 10 can be taken out from the horizontal cylinder 6 at the same time, so as to facilitate the disassembly of the filter ring 10 and the cleaning of impurities.

[0029] Working principle of the present invention: The lubricating oil in the oil storage tank is pumped into the lubricating device 2 along the oil inlet pipe 4 through the oil pump body 3, thereby lubricating the working parts inside the lubricating device 2, and enters the first oil return pipe 5 along the oil outlet end of the lubricating device 2, and then enters the inside of the horizontal cylinder 6 from the connection between the first oil return pipe 5 and the horizontal cylinder 6. After the lubricating oil enters the inside of the horizontal cylinder 6, it is filtered by the filter ring 10 inside the horizontal cylinder 6. The filter ring 10 is rotated by the action of the one-way rotating mechanism, so that the filter holes 1001 on the surface of the filter ring 10 rotate to the bottom during the rotation and participate in the filtering work of the lubricating oil, reducing the influence of the blockage of some filter holes 1001 on the filtering efficiency, and the lubricating oil is filtered. After being filtered by the filter hole 1001, it flows into the interior of the connecting shell 7, and enters the second oil return pipe 8 along the connection between the connecting shell 7 and the second oil return pipe 8, and finally flows back to the oil storage tank body 1, thereby performing circulating flow lubrication on the lubricating equipment 2. When the filter ring 10 rotates to filter the lubricating oil, the solid impurities generated by the internal filtration of the filter ring 10 are continuously pushed toward the sealing cover plate 9 by the action of the impurity pushing mechanism, and are collected by the action of the impurity collecting mechanism, so that the impurities are gathered at the end of the filter ring 10 away from the first oil return pipe 5, and the impurities are kept away from the contact and filtration position of the lubricating oil and the filter ring 10, thereby reducing the influence of the increase of impurities on the filtration efficiency of the lubricating oil and ensuring the filtration efficiency of the lubricating oil.
