DETAILED DESCRIPTION

[0017] The technical solutions of the present application will be further specifically described below by examples, and combined with the accompanying Figures 1-2 drawings.

[0018] An extraction tank for rare earth extraction includes a tank body 1, a discharge pipe 2 at the bottom of the tank body 1, a feed pipe 3 and a motor 4 on the top cover plate of the tank body 1, a rotating shaft 5 extending into the tank body 1 on the motor 4, and a stirring paddle 6 on the rotating shaft 5.

[0019] The tank body 1 has a lower grinding seat 7 at the top, which divides it into a grinding chamber 101 and an extraction chamber 102. The lower grinding seat 7 has a conical grinding groove 8 at the top and a material outlet 9 at the bottom for the rotating shaft 5 to pass through. The grinding chamber 101 has an upper grinding seat 10 that is adapted to the grinding groove 8 and is fixed on the rotating shaft 5. The side wall of the tank body 1 above the extraction chamber 102 has a liquid inlet pipe 11. The rotating shaft 5 at the top of the extraction chamber 102 also has a boss 12 and a fan blade 13 located above the boss 12.

[0020] A heating mechanism I14 is also provided on the outside of the tank body 1. The heating mechanism I14 is connected to the heating mechanism II15 in the rotating shaft 5 and the stirring paddle 6 through two sets of circulation pipes 16. A pump body 17 is provided on one set of circulation pipes 16.

[0021] The heating mechanism I14 includes a jacket 141 disposed on the outside of the tank body 1. A liquid storage chamber 142 is formed between the jacket 141 and the side wall of the tank body 1. Two sets of circulation pipes 16 are connected at one end to the liquid storage chamber 142. Water inlet pipes and water outlet pipes are respectively disposed on the upper and lower side walls of the liquid storage chamber 142. A heating plate 143 is also disposed inside the liquid storage chamber 142.

[0022] The heating mechanism II15 includes a mounting base 151 located on the top of the cover plate for the shaft 5 to pass through. The mounting base 151 has an inlet chamber 152 and an outlet chamber 153 arranged vertically and horizontally for the shaft 5 to pass through. A circulation pipe 16, on which the pump body 17 is installed, is connected to the inlet chamber 152, and another set of circulation pipes 16 is connected to the outlet chamber 153. A U-shaped heating channel I154 is provided in the side wall of the shaft 5. The two ends of the U-shaped heating channel I154 are connected to the corresponding inlet chamber 152 and outlet chamber 153, respectively. A U-shaped heating channel II155 extends outward from the U-shaped heating channel I154 to the side wall of the corresponding stirring paddle 6.

[0023] like Figure 1 As shown, the top of the upper grinding seat 10 is provided with a guide slope I18, and the feed pipe 3 is located directly above the guide slope I18.

[0024] like Figure 1 As shown, the inner diameter of the discharge port 9 is larger than the diameter of the rotating shaft 5, the diameter of the boss 12 is larger than the inner diameter of the discharge port 9, and the top of the boss 12 is provided with a guide slope II19.

[0025] The working principle of the present application is as follows: the rare earth raw material is introduced into the grinding cavity 101 through the feeding pipe 3, wherein the raw material flows to the gap between the upper grinding seat 10 and the side wall of the grinding groove 8 through the flow guide slope I18, at this time the motor 4 drives the upper grinding seat 10, the fan blade 13, the convex seat 12 and the stirring paddle 6 to rotate through the rotating shaft 5, and the raw material is ground through the rotating upper grinding seat 10 and the grinding groove 8, and when the ground raw material falls through the discharge port 9, the rotating fan blade 13 can scatter the raw material to prevent the raw material from clumping and affecting the subsequent extraction work, at this time the scattered raw material falls on the convex seat 12 in the rotating process along the top flow guide slope II19 and falls into the extraction cavity 102, in the above process, since the upper grinding seat 10 and the convex seat 12 are driven to rotate by the rotating shaft 5, the raw material is not easy to accumulate on the flow guide slope I18 on the top of the upper grinding seat 10 and the flow guide slope II19 on the top of the convex seat 12, and at the same time, the airflow generated by the rotation of the fan blade 13 can suck the raw material between the grinding groove 8 and the upper grinding seat 10 to flow out of the above gap;

[0026] When the raw material falls into the extraction cavity 102, the extraction liquid is added into the extraction cavity 102 through the liquid inlet pipe 11, so that the raw material is extracted by the rotating stirring paddle 6, and since there is the shielding of the convex seat 12, the splashing liquid generated during the extraction of the raw material is not easy to splash into the discharge port 9 and enter the grinding groove 8, so as to ensure the dryness of the grinding groove 8;

[0027] At the same time, the liquid in the liquid storage cavity 142 is heated by the heating plate 143, so that the heat of the liquid heats the raw material on the inner edge through the side wall of the tank body 1, and at the same time, the heated liquid in the liquid storage cavity 142 is pumped into the liquid inlet cavity 152 through one of the circulating pipes 16 by the pump body 17, then flows into the U-shaped heating channel I 154 and the U-shaped heating channel II 155, and then flows back to the liquid outlet cavity 153, and finally flows back to the liquid storage cavity 142 through the other group of circulating pipes 16 to be heated by the heating plate 143, so as to realize the circulation of the heated liquid. When the heated liquid flows in the U-shaped heating channel I 154 and the U-shaped heating channel II 155, the heat is transferred to the middle different areas in the extraction cavity 102 through the rotating shaft 5 and the side wall of the stirring paddle 6 in the rotating process, so as to ensure the heating effect and efficiency of different areas in the extraction cavity 102, thereby improving the extraction effect and efficiency of the raw material. When the rotating shaft 5 rotates in the liquid inlet cavity 152 and the liquid outlet cavity 153, the two ends of the U-shaped heating channel I 154 are always in communication with the corresponding liquid inlet cavity 152 or liquid outlet cavity 153, so as to ensure the normal flow of liquid between them.

[0028] The application has been described in detail, but the content described is only the preferred embodiment of the application, and cannot be considered as limiting the scope of the application. Any equivalent changes and improvements made in the scope of the application should still belong to the patent scope of the application.
