[0025] As Figures 1-7As shown, in this embodiment, a centrifugal waste lubricating oil precipitation device includes a box body 1 and support legs 2 arranged at the four corners of the bottom of the box body 1. A centrifugal mechanism is arranged in the box body 1. A driving mechanism matched with the centrifugal mechanism is arranged on the right side wall of the box body 1. The driving mechanism includes a variable speed motor 3 fixed to the right side wall of the box body 1 through a motor support 4. The output shaft of the variable speed motor 3 horizontally penetrates the right side wall of the box body 1 and is connected with a transmission shaft 5 horizontally arranged in the box body 1. The end of the transmission shaft 5 is connected with the centrifugal mechanism through a driving assembly. A liquid inlet pipe 6 is arranged on the left side wall of the box body 1. The liquid inlet pipe 6 horizontally penetrates the left side wall of the box body 1 and extends into the centrifugal mechanism. A filter is horizontally arranged in the box body 1 below the centrifugal mechanism. A liquid outlet pipe 7 is vertically arranged at the bottom center of the box body 1.

[0026] Optionally, the centrifugal mechanism includes a horizontally arranged inner cylinder 8. A plurality of first through holes 9 are arranged on the side wall of the inner cylinder 8. First sealing end covers 10 are symmetrically arranged at the left and right openings of the inner cylinder 8. A right inner sleeve pipe 11 movably sleeved on the transmission shaft 5 is arranged on the right side inner wall of the box body 1 at the position corresponding to the transmission shaft 5. A right outer sleeve pipe 12 sleeved on the right inner sleeve pipe 11 is arranged on the right side wall of the right sealing end cover 10. A plurality of first bearings 13 matched with the right outer sleeve pipe 12 are arranged on the right inner sleeve pipe 11. The driving assembly is arranged on the first sealing end cover 10 in the right outer sleeve pipe 12. The inner end of the liquid inlet pipe 6 horizontally penetrates the central position of the left sealing end cover 10 and extends into the inner cylinder 8. A left inner sleeve pipe 14 movably sleeved on the liquid inlet pipe 6 is arranged on the outer wall of the first sealing end cover 10 at the position corresponding to the liquid inlet pipe 6. A left outer sleeve pipe 15 sleeved on the left inner sleeve pipe 14 is arranged on the left side inner wall of the box body 1. A plurality of second bearings 16 matched with the left outer sleeve pipe 15 are arranged on the left inner sleeve pipe 14.

[0027] Optionally, the driving assembly includes a plurality of clamping strips 17 arranged on the outer wall of the first sealing end cover 10 along the circumferential direction of the right outer sleeve pipe 12. A clamping groove 18 matched with each clamping strip 17 is arranged at the end of the transmission shaft 5 corresponding to the clamping strip 17.

[0028] Optionally, the system also includes an outer cylinder 19 fitted around the inner cylinder 8. Several second through holes 20 are provided on the side wall of the outer cylinder 19. A second sealing end cap 21, movably fitted onto the left inner sleeve 14, is provided at the left end opening of the outer cylinder 19. A linkage component cooperating with the left inner sleeve 14 is provided inside the second sealing end cap 21. A third sealing end cap 22, movably fitted onto the right outer sleeve 12, is provided at the right end opening of the outer cylinder 19. A support sleeve 23, fitted onto the right outer sleeve 12, is provided on the right side wall of the third sealing end cap 22. A third bearing 24, cooperating with the support sleeve 23, is provided on the right outer sleeve 12. Secondary centrifugation is performed through the outer cylinder 19. Because the speed of the outer cylinder 19, driven by the linkage component, is not the same as the rotation speed of the inner cylinder 9, a speed difference is formed, ensuring better filtration of the lubricating oil thrown into the outer cylinder 19 during rotation. It should be noted that the diameter of the second through hole 20 is smaller than that of the first through hole 9, thus it can filter smaller iron filings and effectively improve the filtration accuracy.

[0029] Optionally, the linkage includes an annular groove 25 disposed in the left side wall of the second sealing end cover 21 along the circumferential direction of the second sealing end cover 21, a plurality of first locking teeth 26 uniformly disposed along the circumferential direction on the outer wall of the left inner sleeve 14 corresponding to the position of the annular groove 25, at least three sets of transmission gears 27 uniformly spaced along the circumferential direction in the annular groove 25, the locking shaft 28 of each transmission gear 27 being movably engaged with the inner wall of the annular groove 25, and each transmission gear 27 meshing with the corresponding first locking teeth 26; and second locking teeth 29 meshing with each transmission gear 27 are respectively disposed on the inner wall of the annular groove 25 outside the transmission gear 27.

[0030] Optionally, a limiting disc 30 is provided on the right outer sleeve 12 to abut against the support sleeve 23. When the outer cylinder 19 rotates, the limiting disc 30 can ensure that its rotation position remains unchanged, thereby limiting its rotation position, reducing the shaking caused by the operation of the linkage, and improving its operational stability.

[0031] Optionally, the filter element includes a filter plate frame 31, with protrusions 32 symmetrically arranged on the left and right sides of the inner wall of the housing 1. The left and right sides of the filter plate 31 are movably engaged with the protrusions 32 inside the housing. A cellulose filter layer 33 is provided inside the filter plate frame 31. A plurality of filter strip holes 34 are evenly spaced on the filter plate frame 31. Handles 35 are symmetrically arranged on the left and right sides of the surface of the filter plate frame 31.

[0032] Optionally, the side wall of the housing 1 below the protrusion 32 is inclined inward and shaped like a funnel. The funnel shape can better collect the lubricating oil.

[0033] Before use, the oil outlet pipe of the oil storage tank needs to be connected to the liquid inlet pipe 6 of the box body, and the valve is opened to allow the lubricating oil to enter the inner cylinder 8 through the liquid inlet pipe 6. With the start of the variable speed motor 3, the output shaft of the variable speed motor 3 drives the transmission shaft 5 to rotate radially, and then through the clamping of each clamping groove 18 at the end of the transmission shaft 5 in the clamping strip 17, the inner cylinder 8 is driven to rotate. The first sealing end cover on the left side of the inner cylinder 8 is stably supported by the left outer sleeve 15 and smoothly rotates under the action of the left inner sleeve 14 and the second bearing 16. The first sealing end cover 10 on the right side is stably supported by the right outer sleeve 12 and smoothly rotates under the action of the right inner sleeve 11 and the first bearing 13. Through the rotation of the inner cylinder 8, the throwing of the lubricating oil is accelerated, and the lubricating oil enters the outer cylinder 19 through the first through holes 9, and the large iron filings are left in the inner cylinder 8. The variable speed rotation of the variable speed motor 3 can prevent the iron filings from being stuck in the first through holes 9 for a long time, thereby improving the filtering effect, and can also gather the iron filings to form a "filter layer" to better filter the lubricating oil. With the rotation of the inner cylinder 8, each first clamping tooth 26 is driven to rotate, thereby driving the transmission gear 27 engaged therewith to rotate, and each transmission gear 27 transmits force to the outer cylinder 19 through each second clamping tooth 29, thereby driving the outer cylinder 19 to rotate at a decreasing speed, and thereby filtering the lubricating oil flowing into the outer cylinder 19 for the second time. The filtered lubricating oil flows into the box body 1 and is filtered by the cellulose filter layer 33 in the filter plate frame 31 for the third time to filter out the fine dust therein. It has reasonable structure design, convenient operation, adopts centrifugal separation mode, can quickly separate the iron filings in waste lubricating oil, even if the iron filings are stuck in the filter holes, the lubricating oil can be filtered out under the action of centrifugal force, and at the same time, the separated lubricating oil can be separated for the second time to filter out the fine dust therein. The equipment can be used for a long time without regular cleaning, the accumulated iron filings form a "filter screen" during rotation to assist in filtering, further improve the separation effect, save time and effort, greatly shorten the sedimentation time, and make the equipment can be used continuously for a long time, thereby solving the problems in the prior art.
