DETAILED DESCRIPTION

[0026] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0027] The oil removal device for rare earth liquid in an embodiment of the present application is described below with reference to the accompanying drawings.

[0028] like Figure 1-Figure 6 As shown, the oil removal device for rare earth liquid according to the embodiment of the present application may include a frame 10 , an oil removal assembly 30 and a stirring shaft 40 .

[0029] The frame 10 may include a first cylinder 11, a third cylinder 13 and a second cylinder 12 connected in sequence, wherein a first inlet 111 is provided on the top plate of the first cylinder 11, a plurality of first outlets 112 are provided circumferentially on the bottom plate, the first cylinder 11 and the third cylinder 13 are connected through the first outlets 112, and an opening and closing member 20 is provided in the first cylinder 11. A plurality of second inlets 121 are provided circumferentially on the top plate of the second cylinder 12, a second outlet 122 is provided on the bottom plate, the second cylinder 12 and the third cylinder 13 are connected through the second inlet 121, and the two ends of the second cylinder 12 are connected to the first cylinder 11 and the second cylinder 12 respectively. The third cylinder 13 is hollow inside and open at both ends, and an operation port 131 is provided on the third cylinder 13.

[0030] It should be noted that the opening and closing member 20 described in this embodiment can flexibly control the closed or open state of the first cylinder 11 under the premise of ensuring the smooth rotation of the stirring shaft 40. When the first cylinder 11 is closed, the feed liquid can be stably mixed under the drive of the stirring shaft 40; when the first cylinder 11 is opened, the feed liquid can be discharged from the cylinder through the collar 211 and the first outlet 112 in sequence. This design ensures that the feed liquid can be mixed first and then transported, and the fully stirred feed liquid can be more effectively deoiled.

[0031] The oil removal assembly 30 may include a positioning tube 31, a rotating disk 32, a plurality of connecting tubes 33 and a plurality of oil-absorbing papers 34, wherein the positioning tube 31 is fixedly arranged in the middle of the third cylinder 13, and its two ends are respectively connected to the first cylinder 11 and the second cylinder 12. The rotating disk 32 is movably sleeved on the outside of the positioning tube 31, and a first driving mechanism 50 is connected thereto. It should be noted that the first driving mechanism 50 described in this embodiment can accurately control the rotation of the rotating disk 32. The first driving mechanism 50 may include a first motor 51, a driving wheel 52 and a belt 53, wherein the first motor 51 is arranged on the outside of the third cylinder 13, the driving wheel 52 is connected to the rotating disk 32 through the belt 53, and the third cylinder 13 is provided with a through hole for the belt 53 to pass through (not shown in the figure). The first motor 51 is started, and the first motor 51 drives the driving wheel 52 to rotate, and while the driving wheel 52 rotates, the rotating disk 32 can rotate synchronously through the belt 53.

[0032] The rotating disk 32 is in sliding contact with the end of the first outlet 112. A sealing ring 1121 is sleeved on one end of the first outlet 112, and the sealing ring 1121 is in contact with the rotating disk 32. A plurality of through holes 321 are opened circumferentially on the rotating disk 32. Both sides of the through holes 321 are respectively connected with the corresponding first outlet 112 and the corresponding connecting pipe 33. The connecting pipe 33 is connected with the corresponding second inlet 121, and an opening and closing door 331 is provided on the connecting pipe 33. The oil-absorbing paper 34 is detachably arranged in the corresponding second outlet 122.

[0033] It should be noted that the number of the first outlet 112, the second inlet 121 and the connecting tube 33 described in this embodiment is the same and corresponds one to one, while the number of the through holes 321 is less than the number of the connecting tubes 33, thereby ensuring that at least one connecting tube 33 is blocked by the rotating disk 32, and the corresponding oil absorbing paper 34 can be replaced through the blocked connecting tube 33.

[0034] As shown in the attached Figure 6 As shown, in the embodiment of the present application, the number of through holes 321 is one less than the number of connecting tubes 33 .

[0035] One end of the stirring shaft 40 is arranged in the positioning tube 31 and connected to the second driving mechanism 60 in the positioning tube 31, and the other end of the stirring shaft 40 passes through the bottom plate of the first cylinder 11 and is provided with a stirring blade 41. The second driving mechanism 60 may include a second motor 61, a cylinder 62 and a mounting seat 63, wherein the output end of the second motor 61 is connected to the stirring shaft 40. The output end of the cylinder 62 is connected to the mounting seat 63, the second motor 61 is arranged on the mounting seat 63, and the mounting seat 63 is slidably connected to the inner wall of the positioning tube 31.

[0036] It should be noted that the second driving mechanism 60 described in this embodiment can control the rotation and lifting operations of the stirring shaft 40. When it is necessary to control the rotation of the stirring shaft 40, it is only necessary to start the second motor 61; when it is necessary to control the lifting of the stirring shaft 40, it is only necessary to start the cylinder 62, and the cylinder 62 can drive the mounting base 63, the second motor 61 and the stirring shaft 40 to lift and lower.

[0037] Specifically, when it is necessary to remove oil from the rare earth liquid, the relevant personnel first control the movement of the partition plate 21 through the cylinder 62, so that the ring 211 is sleeved on the outside of the sealing sleeve 22. At this time, the first cylinder 11 is in a closed state. Then, the rare earth liquid is transferred from the first inlet 111 to the first cylinder 11. The rare earth liquid is located above the partition plate 21, and then the second motor 61 is started, so that the second motor 61 drives the stirring shaft 40 to rotate, thereby fully stirring and mixing the rare earth liquid.

[0038] After the rare earth liquid is fully mixed, the relevant personnel control the movement of the partition plate 21 through the cylinder 62, so that the ring 211 moves and separates from the sealing sleeve 22, and the first cylinder 11 is turned to the open state. At this time, the rare earth liquid above the partition plate 21 can enter the bottom of the partition plate 21 through the ring 211, and is discharged from the multiple first outlets 112 on the bottom plate of the first cylinder 11 to the corresponding through holes 321, and then enters the corresponding second inlet 121 through the corresponding connecting pipe 33, and finally enters the second cylinder 12 after being effectively filtered and deoiled by the oil-absorbing paper 34.

[0039] When performing the filtering and oil removal process of the rare earth liquid, the connecting pipe 33 connected to the oil absorbing paper 34 to be replaced can be timely closed by accurately controlling the rotation of the rotating disk 32. At this time, by starting the opening and closing door 331 on the connecting pipe 33, the oil absorbing paper 34 can be quickly and conveniently replaced inside the connecting pipe 33. At the same time, the remaining connecting pipes 33 continue to smoothly transport the rare earth liquid between the first outlet 112 and the second inlet 121, thereby ensuring that the filtering and oil removal operation is carried out uninterruptedly, thereby ensuring efficient oil removal efficiency.

[0040] In one embodiment of the present application, Figure 2-Figure 4 , Figure 6 As shown, the opening and closing member 20 may include a partition plate 21 and a plugging sleeve 22, wherein the partition plate 21 is slidably disposed inside the first cylinder 11, a linear rail 113 is disposed on the inner wall of the first cylinder 11, the linear rail 113 is parallel to the stirring shaft 40, and the partition plate 21 is detachably connected to the linear rail 113 for sliding. The partition plate 21 can be lifted and lowered inside the first cylinder 11.

[0041] A collar 211 is provided through the middle of the partition plate 21, and the collar 211 is extended toward the bottom plate of the first cylinder 11. The plugging sleeve 22 is provided on the bottom plate of the first cylinder 11, and the collar 211 is movably sleeved on the outside of the plugging sleeve 22. The stirring shaft 40 movably penetrates the plugging sleeve 22 and the collar 211, and the stirring blade 41 is located above the partition plate 21. An annular groove 2111 is provided inside the collar 211, and a slider 42 is provided on the outside of the stirring shaft 40, and the slider 42 is slidably provided in the annular groove 2111.

[0042] It should be noted that the partition plate 21 described in this embodiment is linearly connected to the first cylinder 11, and the stirring shaft 40 is connected to the collar 211 through multiple sliders 42. When the stirring shaft 40 moves up and down, the multiple sliders 42 can drive the partition plate 21 to perform synchronous lifting and lowering operations. When the stirring shaft 40 rotates, the multiple sliders 42 slide in the annular groove 2111. At this time, since the height of the stirring shaft 40 is fixed, the height of the partition plate 21 also remains stable. Therefore, under the premise of ensuring the smooth rotation of the stirring shaft 40, the opening and closing member 20 can smoothly and flexibly control the closed or open state of the first cylinder 11.

[0043] Specifically, relevant personnel can control the connection state of the collar 211 and the sealing sleeve 22 by controlling the lifting of the partition plate 21. When the collar 211 is separated from the sealing sleeve 22, the first cylinder 11 is in an open state, and the rare earth liquid above the partition plate 21 can pass through the collar 211 into the bottom of the partition plate 21 and be discharged from the multiple first outlets 112 on the bottom plate of the first cylinder 11.

[0044] When the sleeve ring 211 is tightly sleeved on the outside of the sealing sleeve 22, the inner space of the sleeve ring 211 is blocked by the sealing sleeve 22. At this time, the first cylinder 11 is in a closed state, and the rare earth liquid exists in the space above the partition plate 21. At this time, the stirring shaft 40 is driven to rotate by the second motor 61 to realize the stirring operation of the rare earth liquid, so that the liquid can be fully mixed.

[0045] In summary, the rare earth liquid oil removal device of the embodiment of the present application can realize the convenient replacement of oil absorbing paper during the filtering and oil removal process of the rare earth liquid, ensure the uninterrupted filtering and oil removal operation, and thus ensure efficient oil removal efficiency.
