[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] The connecting rod and the stirring rod outside the connecting rod are driven by the driving motor to rotate at high speed to mix the rare earth polishing powder and the precipitant in the processing box, and the rare earth polishing powder and the precipitant in the processing box are heated by the electric heating wire. Figure 1-4 As shown, the sedimentation device for producing rare earth polishing powder described in the present invention includes a sedimentation and classification box 1, the bottom of the sedimentation and classification box 1 is equidistantly connected to a conical bottom plate 8 by bolts, the top of the sedimentation and classification box 1 located between the conical bottom plates 8 is fixed with a baffle 9 by bolts, one end of the sedimentation and classification box 1 is provided with a processing box 2, the top of the processing box 2 is welded with a top plate 3, the top of the top plate 3 is provided with a stirring assembly 5, and the inside of the processing box 2 is provided with a heating assembly 4;

[0024] The stirring assembly 5 includes a driving motor 501 installed on the top of the top plate 3 through a mounting bracket. The output shaft of the driving motor 501 located inside the processing box 2 is connected to a connecting rod 502 through a connecting sleeve. A stirring rod 503 is welded equidistantly on the outside of the connecting rod 502. The heating assembly 4 includes a stainless steel plate 401 fixed to the inside of the processing box 2 by bolts. Electric heating wires 402 are equidistantly fixed inside the stainless steel plate 401 by bolts. The interior of the stainless steel plate 401 located outside the electric heating wire 402 is filled with magnesium oxide powder 403.

[0025] During use, the mixed and reacted rare earth polishing powder flows in the sedimentation and grading box 1, is blocked by the baffle 9 and is settled and graded on the conical bottom plate 8. The driving motor 501 drives the connecting rod 502 and its outer stirring rod 503 to rotate, mixing the rare earth polishing powder and precipitant in the processing box 2. The electric heating wire 402 can heat the rare earth polishing powder and precipitant in the processing box 2.

[0026] For example, Figure 4 As shown, the utility model also includes that the end of the sedimentation and classification box 1 away from the treatment box 2 is connected to the filter assembly 7 through a pipeline, and the filter assembly 7 includes a box body 701 connected to one end of the sedimentation and classification box 1 through a pipeline, and a filter screen 702 is fixed to the inside of the box body 701 by bolts.

[0027] When in use, the filter 702 can filter the suspended matter on the surface of the liquid, and the filtered suspended matter falls into the box body 701.

[0028] For example, Figure 4 As shown, the present invention further includes that a liquid outlet pipe 6 is connected to one side of the box body 701 through a threaded groove, and an end cover 703 is fixed to the bottom of the box body 701 through bolts.

[0029] When in use, the liquid in the treatment box 2 is discharged through the box body 701 and the liquid outlet pipe 6. Opening the end cover 703 can allow the suspension in the box body 701 to flow out.

[0030] For example, Figure 1 、 Figure 3 As shown, the utility model also includes that a temperature controller 10 is installed at one end of the sedimentation and grading box 1 through a mounting seat, the detection end of the temperature controller 10 is located inside the processing box 2, and the current output end of the processing box 2 is electrically connected to the current input end of the electric heating wire 402 through a power line.

[0031] When in use, the heating of the electric heating wire 402 and its heating temperature can be controlled by the temperature controller 10 .

[0032] For example, Figure 1 As shown, the present invention further includes that one side of the processing box 2 is connected to a solenoid valve 11 through a pipeline, and the side of the solenoid valve 11 away from the processing box 2 is connected to a discharge pipe 12 through a threaded groove.

[0033] When in use, the solenoid valve 11 is opened to allow the mixed and reacted rare earth polishing powder in the processing box 2 to flow into the sedimentation and classification box 1 through the discharge pipe 12.

[0035] When in use, the support columns 13 are used to support the processing box 2 .

[0036] When the utility model is used, a person uses a power cord to connect the device to an external power source, and pours rare earth polishing powder, precipitant and water into the processing box 2;

[0037] Turn on the drive motor 501 to drive the connecting rod 502 and the stirring rod 503 outside it to rotate at high speed, so as to mix the rare earth polishing powder and the precipitant in the processing box 2. The mixed rare earth polishing powder is easy to settle and classify;

[0038] The electric heating wire 402 is heated by the temperature controller 10, and the temperature of the electric heating wire 402 is transferred to the stainless steel plate 401, thereby heating the rare earth polishing powder and precipitant in the processing box 2, thereby improving the reaction efficiency.

[0039] Open the solenoid valve 11 to allow the mixed and reacted rare earth polishing powder in the processing box 2 to flow into the sedimentation and classification box 1 through the discharge pipe 12. The rare earth polishing powder entering the sedimentation and classification box 1 is blocked by the baffle 9 and settles on the conical bottom plate 8. As more and more rare earth polishing powder flows into the sedimentation and classification box 1, it is classified by multiple conical bottom plates 8 and baffles 9.

[0040] The settled and classified liquid and the suspended matter floating on the liquid surface flow out through the liquid outlet pipe 6, and the filter 702 in the box body 701 can block the suspended matter and make it fall into the box body 701. Opening the filter 702 can make the suspended matter in the box body 701 flow out.
