Description

Technical Field

[0001] This utility model relates to the field of lubricating oil storage technology, and in particular to a lubricating oil storage device. Background Technology

[0002] Lubricating oil is used in various types of automobiles and mechanical equipment. Its main function is to protect internal machine components and reduce wear. Additionally, lubricating oil also has functions such as cooling, sealing, buffering, and cleaning. Lubricating oil needs to be changed periodically after a certain period of use; therefore, the quality of the lubricating oil directly determines the frequency of replacement. However, the storage of lubricating oil has always been a significant problem. Most lubricating oil is stored in drums or tanks, but these storage devices cannot effectively remove air from the drum. Furthermore, during the filling process, lubricating oil is poured from a height to the bottom of the drum, and the height difference causes the lubricating oil to easily mix with air. This air is difficult to expel quickly. If this air cannot be removed in time, it will cause the lubricating oil to oxidize or deteriorate during storage, thus shortening its service life. In addition, existing technologies also include drums with agitator impellers. However, in actual use, these impellers cannot quickly remove air from the lubricating oil. The main reason is that a single impeller drives the lubricating oil to rotate, and the impeller cannot move up and down to agitate the entire mixture. Therefore, these devices cannot effectively solve this technical problem. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, this utility model provides a lubricating oil storage device with a reasonable structural design and convenient operation. On the one hand, by reducing the height difference during filling, the probability of air mixing into the lubricating oil is reduced. On the other hand, the multi-impeller stirring setting can significantly improve the stirring effect and can move up and down in the tank for stirring, so that the air mixed in with the lubricating oil can be quickly expelled, which is beneficial to the storage of lubricating oil, improves the quality of lubricating oil, and solves the problems existing in the prior art.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] A lubricating oil storage device includes a barrel and several support legs at the bottom of the barrel.

[0022] like Figure 1-7As shown, in this embodiment, a lubricating oil storage device includes a barrel 1 and several support legs 2 disposed at the bottom of the barrel 1. An inner cylinder 3 is vertically disposed inside the barrel 1 and communicates with the center of its top plate 101. A boss 4 is provided on the inner wall of the lower part of the inner cylinder 3 along its circumferential direction. A vertically disposed cylinder 5 is fixed to the boss 4 by a connecting plate 6. The end of its piston rod moves downward through the boss 4 and is connected to a lifting seat 7 disposed inside the barrel 1. Several support arms 8 are evenly spaced along their circumferential direction on the side wall of the lifting seat 7. Each support arm 8 has a stirring component at its outer end; a locking protrusion 9 is provided on the upper part of the inner wall of the barrel 1 along its circumference, and a floating component movably sleeved on the piston rod of the cylinder 5 is movably locked onto the locking protrusion 9 of the barrel 1; an oil inlet pipe 10 is connected to the side wall of the barrel 1 above the floating component, and a one-way valve 11 is provided on the oil inlet pipe 10; an exhaust pipe 12 is connected to the top plate 101 of the barrel 1, and a one-way exhaust valve 13 is provided on the exhaust pipe 12; an oil outlet pipe 14 is connected to the bottom plate 102 of the barrel 1, and a switch valve 15 is provided on the oil outlet pipe 14.

[0023] Optionally, the stirring component includes a lead screw 16 vertically disposed inside the barrel 1. The upper end of the lead screw movably passes through the float and is connected to the top plate 101 of the barrel 1, while its lower end is connected to the bottom plate 102 of the barrel 1. A fixed sleeve 17 is movably sleeved on the lead screw 16 at the outer end of the support arm 8. An impeller sleeve 18 is movably sleeved on the lead screw 16 below the fixed sleeve 17. Several stirring blades 19 are evenly spaced along the circumference on the outer wall of the impeller sleeve 18. The impeller sleeve 18 is movably connected to the fixed sleeve 17 through a positioning sleeve 20 disposed on its surface. The inner walls of both the impeller sleeve 18 and the positioning sleeve 20 are threadedly connected to the lead screw 16.

[0024] Optionally, a groove 21 is provided at the bottom of the lifting seat 7, and several diversion holes 22 connected to the groove 21 are provided on the surface of the lifting seat 7 outside the piston rod of the cylinder 5. A protrusion 23 is provided in the center of the inner wall of the groove 21 corresponding to the position of the piston rod of the cylinder 5. On the one hand, the air accumulated at the bottom of the lifting seat 7 can be discharged outward in time through the groove 21. On the other hand, the air can be discharged directly upward through the diversion holes 22 and will not flow into the bottom of the barrel further with the stirring.

[0025] Optionally, the floating component includes a hollow floating shell 24, with an inner hole 25 in the center of the floating shell 24 for the piston rod of the cylinder 5 to pass through, and an outer hole 26 on the floating shell 24 corresponding to the position of each lead screw 16 for it to pass through. Several inwardly recessed notches 27 are provided at intervals along the circumference on the outer wall of the floating shell 24. The center of the floating shell 24 is recessed downward, and several guide strips 28 are provided on the surface of the floating shell 24 along the circumference.

[0026] Optionally, a plurality of sealing rings 29 are provided at intervals from top to bottom on the inner wall of the boss 4, abutting against the piston rod of the cylinder 5. The sealing rings 29 can improve the sealing performance inside the barrel 1.

[0027] In use, lubricating oil enters the barrel 1 through the oil inlet pipe 10. The one-way valve 11 prevents the lubricating oil from flowing backward. The lubricating oil first flows to the floating shell 24 and then converges towards the central depression. It flows through the inner hole 25 to the piston rod of the cylinder 5, and through the outer holes 26 to the corresponding lead screws 16. Finally, it flows into the bottom of the barrel 1. This effectively reduces the mixing of a large number of air bubbles with the lubricating oil caused by the height difference during filling. In addition, during the filling of lubricating oil, the air in the barrel 1 can be discharged through the one-way exhaust valve 13 of the exhaust pipe 12, ensuring continuous filling of lubricating oil. After filling is completed, the cylinder 5 is activated. The piston rod of the cylinder 5 pulls the lifting seat 7 upward, which in turn drives the stirring components to move upward through the support arms 8. Since the impeller sleeve 18 and the positioning sleeve 20 are threadedly connected to the lead screw 16 on the corresponding side, when the support arm 8 pulls the impeller sleeve 18 and the positioning sleeve 20 through the fixed sleeve 17, it causes them to rotate, thereby causing the stirring blade 19 to rotate. This causes the lubricating oil mixed with air in the barrel 1 to be quickly discharged upwards. The discharged air is discharged above the floating shell 24 through the inner hole 25, the outer hole 26 and various notches 27. The floating shell 24 controls the oil storage volume. The lubricating oil in the barrel 1 pushes the floating shell 24 upwards, thereby blocking the oil inlet pipe 10. On the other hand, it also ensures that there is a space in the upper part of the barrel 1, which is convenient for the vacuum equipment to be connected to the end of the exhaust pipe 12 to extract the air in the barrel 1. Its structure is reasonably designed and easy to operate. On the one hand, it can reduce the chance of air mixing into the lubricating oil by reducing the height difference of filling. On the other hand, the multi-impeller agitator can significantly improve the agitation effect and can move up and down in the tank for agitation, so that the air mixed in with the lubricating oil can be quickly expelled, which is beneficial to the storage of lubricating oil, improves the quality of lubricating oil, and solves the problems existing in the prior art.
