[0045] like Figure 1 As shown in the embodiment 1, a rare earth polishing powder waste sedimentation and separation device includes a frame 1, a sedimentation tank 2 is installed on the frame 1, and the sedimentation tank 2 has a waste liquid inlet pipe 3, a recycled material discharge pipe 4, and a clear liquid discharge pipe 5. A first guide plate 6 and a second guide plate 7 are installed in the sedimentation tank 2. The first guide plate 6 and the second guide plate 7 are used to slow down the flow rate of the waste; a vacuum cylinder 8 is installed in the sedimentation tank 2, and the vacuum cylinder 8 is located below the first guide plate 6 and the second guide plate 7 (i.e., the downstream side of the waste flow) and is guided The waste material flows to the vacuum cylinder 8; the vacuum cylinder 8 is used to absorb the recycled material and accelerate the sedimentation rate of the waste material; an inclined plate 9 is installed in the sedimentation tank 2, and the inclined plate 9 is located above the vacuum cylinder 8 (that is, the downstream side of the waste flow), and several inclined plates 9 are arranged at equal intervals. The inclined plate 9 further delays the upward flow of the recycled material and has a sedimentation effect; the present application can absorb the recycled material and accelerate the sedimentation rate of the waste material by setting the vacuum cylinder 8, and at the same time avoid the recycled material after sedimentation from being absorbed again, the supernatant will not be turbid again, and the sedimentation effect is good.

[0046] like Figure 2As shown, as an optimization of Example 1, the sedimentation tank 2 is a thin shell-shaped closed structure, and the sedimentation tank 2 has a first protrusion 10, a second protrusion 11, and a third protrusion 12. The first protrusion 10 and the second protrusion 11 are located on the upper side wall of the sedimentation tank 2, and the first protrusion 10 and the second protrusion 11 are arranged opposite to each other. The first protrusion 10 is used to install the waste liquid inlet pipe 3; the second protrusion 11 is used to install the clear liquid discharge pipe 5; the third protrusion 12 is located on the bottom surface of the sedimentation tank 2, and the third protrusion 12 is used to install the recycled material discharge pipe 4; the sedimentation tank 2 has an arc section 13, which is concentric with the vacuum cylinder 8 and can guide the recycled material into the recycled material discharge pipe 4; the sedimentation tank 2 has a slope section 14, which is parallel to the inclined plate 9 and can guide the recycled material into the recycled material discharge pipe 4. By limiting the structure of the sedimentation tank 2, the sedimentation of the waste can be accelerated, and the collection and discharge of the recycled material are facilitated.

[0047] like Figure 3 As shown, as an optimization of embodiment one, the first guide plate 6 divides the sedimentation tank 2 into a waste slow flow area and a sedimentation area. The first guide plate 6 includes a vertical line segment 15 and an oblique line segment 16. The surface of the vertical line segment 15 is perpendicular to the waste liquid inlet pipe 3. The lower end of the vertical line segment 15 is connected to the oblique line segment 16. The oblique line segment 16 is parallel to the oblique plate 9. The oblique line segment 16 allows the waste to flow toward the arc section 13 of the sedimentation tank 2. By setting the first guide plate 6, the flow rate of the waste is slowed down, and the waste flows toward the vacuum cylinder 8.

[0048] like Figure 3 As shown, as an optimization of Example 1, the second guide plate 7 is arranged at an angle, the surface of the second guide plate 7 is perpendicular to the oblique line segment 16, and the second guide plate 7 is located below the first guide plate 6. The second guide plate 7 further reduces the outlet size of the waste and guides the waste to flow toward the vacuum cylinder 8. By setting the second guide plate 7, the flow rate of the waste is further slowed down, and the waste flows toward the vacuum cylinder 8.

[0049] like Figures 4 to 7As shown, as an optimization of the first embodiment, the vacuum cylinder 8 includes a drum 17, the drum 17 is in the shape of a circular tube, and the side wall of the drum 17 has evenly arranged air extraction holes 18; the outer wall of the drum 17 is fixed with a filter cloth 20 through a C-shaped hoop 19, and the filter cloth 20 covers the air extraction holes 18, and the filter cloth 20 can separate the recycled material outside the vacuum cylinder 8; the two ends of the drum 17 are connected to the circular seat 21; the circular seat 21 is connected to the symmetrically arranged end caps 22 by screws, and the shape of the end caps 22 is a bell-shaped, and the large diameter section of the end cap 22 is aligned with the circular seat 21. The small diameter section of the end cover 22 protrudes from the outside of the drum 17. The center of the end cover 22 has an axial hole 23. A sleeve 25 is fixed to the axial hole 23 through a positioning nut 24. The sleeve 25 is connected to the sedimentation tank 2. The connection method can be fixed connection or rotation connection. The end of the sleeve 25 is located outside the sedimentation tank 2. The two end covers 22 and the drum 17 form a vacuum accommodating chamber. The inner hole of the sleeve 25 is rotatably connected to a sealed bearing 26. The left sealed bearing 26 is rotatably connected to a vacuum tube 27. The outer end of the vacuum tube 27 protrudes from the sleeve 25. The inner end of the vacuum tube 27 is connected to the valve body 28 through a flange, and a partition block 29 is fixed to the inner hole of the valve body 28 by a positioning screw. The partition block 29 is located in the middle of the valve body 28; the left wall of the valve body 28 has a first branch pipe 30 connected to the valve body 28, and the first branch pipe 30 is used to extract the air in the drum 17; the right wall of the valve body 28 has a second branch pipe 31 connected to the valve body 28, and the second branch pipe 31 is connected to the liquid suction pipe 32 through a flange. The lower end of the liquid suction pipe 32 has a liquid suction gap with the inner wall of the drum 17; the sealed bearing 2 on the right side 6 is rotatably connected to a liquid outlet pipe 33, the outer end of the liquid outlet pipe 33 protrudes outside the sleeve 25, and the inner end of the liquid outlet pipe 33 is connected to the right port of the valve body 28 through a flange. The vacuum tube 27 is used to evacuate the accommodating chamber, so that the clear liquid of the waste material enters the drum 17, and the recycled material is separated by the filter cloth 20. The clear liquid in the drum 17 is still mixed with tiny recycled materials. The clear liquid containing tiny recycled materials is discharged from the sedimentation tank 2 through the suction pipe 32 and the liquid outlet pipe 33. Such a vacuum cylinder 8 makes the sedimentation tank 2 have a low-pressure adsorption area, which accelerates the sedimentation efficiency of the waste material.

[0050] like Figure 8 As shown, as an optimization of Example 1, considering that the position of the drum 17 is fixed, the distribution of the recycled material on the filter cloth 20 is uneven, which affects the sedimentation effect; the sleeve 25 is rotatably connected to the sedimentation tank 2, and a driven gear 34 is installed on the sleeve 25 outside the sedimentation tank 2. The driven gear 34 is engaged with a driving gear 35, and the driving gear 35 is driven by a first motor 36. The first motor 36 is provided on a motor base 37, and the motor base 37 is fixed to the frame 1. By providing the first motor 36, the drum 17 can be driven to rotate, and the recycled material on the filter cloth 20 is more evenly distributed, and the separation effect is good.

[0051] like Figure 9As shown, as an optimization of Example 1, considering that the direct discharge of the clear liquid containing tiny recycled materials will cause waste of rare earth polishing powder and pollute the environment; the free end of the liquid outlet pipe 33 is connected to the first delivery pipe 38, and the side wall of the first delivery pipe 38 is installed with a pump body 39. The free end of the first delivery pipe 38 is located in the sedimentation tank 2, and the pipe mouth of the first delivery pipe 38 is located above the waste material inlet pipe 3. By providing the pump body 39, the clear liquid containing tiny recycled materials in the drum 17 enters the sedimentation tank 2 again for sedimentation, ensuring that all the recycled materials can be settled.

[0052] like Figure 10-11 As shown, as an optimization of the first embodiment, considering that the recycled material has been attached to the filter cloth 20, the new recycled material cannot be separated quickly, which affects the vacuum adsorption of the subsequent waste material and reduces the sedimentation efficiency; the inner side of the end cover 22 is connected to a fixing ring 40, the fixing ring 40 is concentric with the sleeve 25, and the outer side wall of the fixing ring 40 is installed with an ear seat 41, the number of the ear seats 41 is 3, and the 3 ear seats 41 are arranged at equal angles. The ear seat 41 is rotatably connected to a shaft rod 42, and the shaft rod 42 is rotatably connected to an arc panel 43. The inner side of the arc panel 43 is adapted to the fixing ring 40, and a part of the arc panel 43 can be placed on the fixing ring 40. On the ring 40, the arc panel 43 is used to hit the inner wall of the drum 17. When the drum 17 rotates clockwise, the fixed ring 40 rotates synchronously. When the arc panel 43 rotates to the 0° position, the arc panel 43 begins to separate from the fixed ring 40 due to gravity factors, until the arc panel 43 hits the drum 17, and the recycled material on the filter cloth 20 will fall off, ensuring the continuous adsorption effect of the vacuum cylinder 8 and improving the sedimentation efficiency. As the arc panel 43 rotates to the 180° position, the arc panel 43 will be placed on the fixed ring 40 again, until the arc panel 43 reaches 0°, the arc panel 43 will be released again, realizing the shedding operation of the recycled material.

[0053] like Figure 12 As shown, as an optimization of Example 1, considering that the recycled material is difficult to be shaken off by the arc panel 43, a first hinged ear 44 is installed in the sedimentation tank 2, and a scraper 45 is hinged on the first hinged ear 44. The tip of the scraper 45 is used to scrape off the recycled material on the filter cloth 20. A second hinged ear 46 is installed in the middle of the scraper 45, and a first telescopic rod 47 is hinged on the second hinged ear 46. The first telescopic rod 47 is hinged to the sedimentation tank 2, and the scraper 45 is driven to rotate by the first telescopic rod 47. The scraper 45 with the adjusted position can scrape off the recycled material on the filter cloth 20, and is used in conjunction with the arc panel 43 to achieve better results.

[0054] like Figure 13 and Figure 14As shown, as an optimization of Example 1, an inverted V-shaped plate 48 is connected to the vertical segment 15, and the V-shaped plate 48 is perpendicular to the vertical segment 15. Multiple groups of V-shaped plates 48 are arranged at equal intervals from top to bottom, and the V-shaped plates 48 on the same layer are arranged at equal intervals. All V-shaped plates 48 are in a tower-shaped structure. The V-shaped plates 48 with a tower-shaped structure are located below the waste liquid inlet pipe 3 and the first conveying pipe 38. The V-shaped plates 48 can further buffer the flow rate of the waste and the clear liquid containing a small amount of recycled material, which is beneficial to the sedimentation operation.

[0055] like Figure 15 and Figure 16 As shown, as an optimization of Example 1, considering that the upper layer of waste in the sedimentation tank 2 still contains polishing powder, a first vertical plate 49 is installed in the sedimentation tank 2, and several first vertical plates 49 are arranged at equal intervals. The first vertical plates 49 are located above the inclined plate 9 (that is, the downstream side of the waste flow), and the first vertical plate 49 close to the clear liquid discharge pipe 5 forms an overflow weir 50; a second vertical plate 51 is installed in the sedimentation tank 2, and several second vertical plates 51 are arranged at equal intervals. The positions of the second vertical plates 51 and the first vertical plates 49 are staggered, and the top surface of the first vertical plate 49 is higher than the bottom surface of the second vertical plate 51. A gap for the passage of waste is formed between the first vertical plates 49 and the second vertical plates 51; a first filter screen 52 is connected to the left side of the first vertical plate 49, and the first filter screen 52 is arranged obliquely. The first filter screen 52 is located at the waist of the first vertical plate 49, and the free end of the first filter screen 52 is connected to the second vertical plate 51. The first filter screen 52 is used to filter the upper layer of waste in the gap, thereby further improving the filtering effect.

[0056] like Figures 17 to 20As shown, the second embodiment is different from the first embodiment in that, considering that the recycled material may adhere to the first filter screen 52, it may become clogged if it is not cleaned for a long time, affecting the sedimentation effect. A third vertical plate 53 is installed in the sedimentation tank 2. Several third vertical plates 53 are arranged at equal intervals. The third vertical plates 53 are located above the inclined plate 9 (i.e., the downstream side of the waste flow). The third vertical plate 53 close to the clear liquid discharge pipe 5 forms an overflow weir 50. The top surface of the third vertical plate 53 has a curved portion 54, and the inclined direction of the curved portion 54 is toward the first guide plate 6; a first spring seat 55 is installed on the side of the third vertical plate 53, and a first spring 56 is installed on the first spring seat 55. The first spring The lower end of 56 is equipped with a second spring seat 57, and the second spring seat 57 is connected to the second filter screen 58. The second filter screen 58 is arranged obliquely, and the free end of the second filter screen 58 is connected to the rotating rod 59; the top surface of the sedimentation tank 2 is provided with a square opening 60, and the square opening 60 is provided with a cover 61, and the cover 61 is provided with a guide rod 62. The surface of the guide rod 62 is perpendicular to the third vertical plate 53, and a carrier plate 63 is slidably connected to the guide rod 62.
