[0024] In order to make the technical means, creative features, achieved purposes, and functions realized by the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with specific embodiments.

[0025] In order to improve the processing efficiency of rare earth polishing powder, as Figures 1-5 shown, a calcination mechanism for an environmentally friendly rare earth polishing powder described in the present utility model includes a frame 1, a heat treatment section 2, and a cold treatment section 3. The heat treatment section 2 and the cold treatment section 3 are respectively arranged at the feeding end and the discharging end at the top of the frame 1, and a driving section for driving the heat treatment section 2 and the cold treatment section 3 to rotate is arranged at the inner bottom of the frame 1;

[0026] The heat treatment unit 2 includes a rotary kiln 21, a first feed sleeve 22, and a first feed hopper 23. The first feed sleeve 22 is connected to the feed end of the rotary kiln 21 through a rotary joint. The first feed hopper 23 is connected to the top of the first feed sleeve 22. The bottom of the first feed sleeve 22 is fixedly connected to the frame 1.

[0027] During use, through the frame 1, the heat treatment unit 2, the cold treatment unit 3, and the drive unit, a calcination mechanism integrating heat treatment and cold treatment is provided for the processing of environmentally friendly rare earth polishing powder, enabling the agglomerated rare earth powder after heat treatment calcination to quickly enter the cold treatment area for rapid cooling, so that the processing personnel can better recycle it, improving the processing efficiency of rare earth polishing powder.

[0028] For heating the powder, exemplarily, as Figures 1-3 shown, the present invention further includes that an induction coil 24 is provided on the outer periphery of one end of the rotary kiln 21 away from the first feed sleeve 22. The input end of the induction coil 24 is arranged on the frame 1. A chain 27 is installed circumferentially in the middle section of the rotary kiln 21. A sprocket 25 is engaged with the bottom of the chain 27. The sprocket 25 is rotatably installed on the top of the frame 1 through a bearing seat. A first synchronous pulley 26 is installed on the shaft head on one side of the sprocket 25 through a key pin.

[0029] During use, the latter half section area of the rotary kiln 21 is heated through the induction coil 24, so that the environmentally friendly rare earth polishing powder raw material passing through the latter half section area in the rotary kiln 21 can be subjected to high-temperature calcination treatment by the induction coil 24.

[0030] For cooling the powder, exemplarily, as Figures 1-4 shown, the present invention further includes that the cold treatment unit 3 includes a stainless steel cylinder 31, a second feed sleeve 32, and a second feed hopper 33. The bottom of the second feed sleeve 32 is connected to the frame 1. The second feed hopper 33 is arranged on the top of the second feed sleeve 32, and the second feed hopper 33 is located at the bottom of the discharge end of the rotary kiln 21. The feed end of the stainless steel cylinder 31 is connected to the discharge end of the second feed sleeve 32 through a rotary joint;

[0031] Radiating fins 34 are connected to the outer periphery of the stainless steel cylinder 31. A fan 35 for increasing the heat exchange between the radiating fins 34 and the air is installed on one side of the frame 1.

[0032] During use, the fan 35 blows air on the surface of the stainless steel cylinder 31 and the radiating fins 34, so that the powder passing through the stainless steel cylinder 31 can be subjected to better cooling treatment.

[0033] The driving part includes a motor 61 installed at the inner bottom of the frame 1. A second synchronous pulley 62 and a third synchronous pulley 63 are successively installed on the driving end of the motor 61. The second synchronous pulley 62 is connected to the first synchronous pulley 26 through a synchronous belt. The third synchronous pulley 63 is connected to a fourth synchronous pulley 64 through a synchronous belt. The fourth synchronous pulley 64 is rotatably installed in the middle of the inner bottom of the frame 1 through a bearing seat.

[0034] An installation sleeve 36 is arranged at the center of the stainless steel cylinder 31. A rotating shaft 37 is installed at the center of the installation sleeve 36 through a key pin. One end of the rotating shaft 37 penetrates through the second feeding sleeve 32 and is connected to the shaft head of the fourth synchronous pulley 64 through a coupling.

[0035] During use, the motor 61 drives the second synchronous pulley 62 and the third synchronous pulley 63 to rotate, so that the second synchronous pulley 62 drives the first synchronous pulley 26 to rotate. Thus, the sprocket 25 connected to the first synchronous pulley 26 drives the chain 27 to run, causing the rotary kiln 21 to rotate with the chain 27. At the same time, the third synchronous pulley 63 drives the fourth synchronous pulley 64 to rotate, so that the rotating shaft 37 connected to the fourth synchronous pulley 64 drives the stainless steel cylinder 31 to rotate.

[0036] The utility model further includes that annular rails 4 are arranged at the ends of the stainless steel cylinder 31 and the rotary kiln 21. Track wheels 5 for supporting the annular rails 4 are respectively installed on the frame 1.

[0037] Wherein, the inner circumferences of the rotary kiln 21 and the stainless steel cylinder 31 are both spiral structures.

[0038] When the utility model is in use, the power supply components around the operation site provide power for the electrical components in this application. The induction coil 24 heats the rear half area of the rotary kiln 21, so that the environmentally friendly rare earth polishing powder raw materials passing through the rear half area in the rotary kiln 21 can be subjected to high-temperature calcination treatment by the induction coil 24. During operation, the motor 61 drives the second synchronous pulley 62 and the third synchronous pulley 63 to rotate, so that the second synchronous pulley 62 drives the first synchronous pulley 26 to rotate. Thus, the sprocket 25 connected to the first synchronous pulley 26 drives the chain 27 to run, causing the rotary kiln 21 to rotate with the chain 27. At the same time, the third synchronous pulley 63 drives the fourth synchronous pulley 64 to rotate, so that the rotating shaft 37 connected to the fourth synchronous pulley 64 drives the stainless steel cylinder 31 to rotate. During this period, the fan 35 blows air on the surface of the stainless steel cylinder 31 and the heat dissipation fins 34, so that the powder passing through the stainless steel cylinder 31 can be cooled better;

[0039] In use, the rare earth polishing powder raw materials to be calcined and heat-treated are fed into the first feed sleeve 22 through the first feed hopper 23. As the rotary kiln 21 rotates, the powder gradually moves from the feed end of the rotary kiln 21 to the discharge end of the rotary kiln 21, so that the powder passes through the area of the induction coil 24 to obtain heat calcination treatment. As the powder moves, it is discharged from the rotary kiln 21 and falls into the second feed hopper 33, and then enters the stainless steel cylinder 31. As the stainless steel cylinder 31 rotates, after being cooled by the heat conduction of the stainless steel cylinder 31 and the heat dissipation fins 34, the powder is cooled and then discharged from the stainless steel cylinder 31. After being collected by the polishing powder processing personnel, it is sent to the next process.
