Simple stirring will still leave some alumina in the corners of the mixing barrel, thus affecting the subsequent production of alumina. Utility Model Content

DETAILED DESCRIPTION
[0019] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0020] like Figure 1-Figure 4The stirring and mixing device for alumina production shown in the figure comprises a bracket 1, a cross frame 2 is fixedly connected to one side of the top of the bracket 1, a stirring barrel 3 is arranged between the bracket 1 and the cross frame 2, a turning mechanism is arranged inside the stirring barrel 3, and the turning mechanism comprises a driving motor 7 arranged inside the cross frame 2, a rotating shaft 8 is fixedly connected to the output end of the driving motor 7, an active bevel gear 11 is fixedly connected to the bottom end of the rotating shaft 8, a transverse rotating shaft 13 is rotatably connected to the inner wall of the stirring barrel 3, a turning blade 14 is arranged on the surface of the transverse rotating shaft 13, and a driven bevel gear 12 is fixedly connected to the side of the transverse rotating shaft 13 away from the stirring barrel 3, the turning mechanism can turn over the alumina precipitated at the bottom of the stirring barrel 3, and at the same time, because the turning blade 14 is tightly attached to the inner wall of the stirring barrel 3, when the precipitated alumina is turned over, it is ensured that no alumina will remain in the corner, the content of alumina in the alumina mixed liquid is ensured, convenience is provided for the subsequent production of alumina, and the quality of the alumina after production can also be ensured.
[0021] A feed port 4 is provided at the top of the stirring barrel 3, and a filter barrel 16 is provided inside the feed port 4. Filter holes 17 are provided on the surface and bottom of the filter barrel 16. The filter barrel 16 can isolate the larger particles of alumina powder in the filter barrel 16, thereby preventing the larger particles of alumina from being easily mixed with the liquid, affecting the ratio of the alumina mixed liquid, and thus affecting the quality of the alumina after production.
[0022] A discharge port 5 is provided at the bottom of the mixing barrel 3, and a solenoid valve 6 is provided at the discharge port 5. The solenoid valve 6 can accurately control the discharge amount of the alumina mixed liquid, and discharge the required amount to avoid waste.
[0023] A plurality of connecting rods 9 are fixedly connected to the surface of the rotating shaft 8, and the other ends of the plurality of connecting rods 9 are fixedly connected to the same stirring blade 10. The stirring blade 10 is arranged inside the stirring barrel 3. The stirring blade 10 can drive the alumina to rotate in the solution, break up the alumina in the solution, increase the contact area between the alumina and the solution, and accelerate the mixing speed of the alumina and the solution.
[0024] A protection box 15 is provided inside the mixing barrel 3, and the active bevel gear 11 and the driven bevel gear 12 cooperate inside the protection box 15. A sealing ring is provided at the outlet of the protection box 15, which can hold alumina powder or easily come into direct contact with the active bevel gear 11 and the driven bevel gear 12, causing the active bevel gear 11 or the driven bevel gear 12 to rust, get stuck, etc., affecting the mixing of alumina.
[0025] There are four transverse rotating shafts 13 in the turning mechanism, and two turning blades 14 are arranged on the surface of each transverse rotating shaft 13. The turning mechanism is located at the bottom end of the mixing barrel 3. Multiple transverse rotating shafts 13 can more effectively turn over the alumina settled in the corners of the mixing barrel 3, so that the alumina floats and the mixing efficiency is accelerated.
[0026] Working principle: First, the alumina powder is introduced into the stirring barrel 3 from the feed port 4, and the alumina with larger particles will be isolated outside. The solution used for mixing can also be added from the feed port 4, and then the drive motor 7 can be started. The drive motor 7 will drive the rotating shaft 8 to rotate, so that the stirring blade 10 stirs the alumina to mix the alumina with the solution. At the same time, through the cooperation between the active bevel gear 11 and the driven bevel gear 12, the horizontal rotating shaft 13 will also rotate while the rotating shaft 8 rotates, thereby driving the flipping blade 14 to flip up and down, so that the alumina that is not mixed with the solution floats up, and at the same time, the alumina is broken up by the stirring blade 10 to increase the contact area between the alumina and the solution and speed up the mixing speed. When the alumina mixed liquid is stationary for a period of time, the alumina will settle at the bottom of the stirring barrel 3, and the upper part will become clear. Before using the alumina mixed liquid, it is necessary to start the drive motor 7 again, and use the flipping mechanism to break up the alumina that has sunk to the bottom again and mix it with the solution again. At this time, the alumina mixed liquid can be put into use.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
