DETAILED DESCRIPTION

[0030] Example 1: As Figures 1 to 6As shown, a kind of reaction kettle mixing assembly, including reaction kettle body 1, when using reaction kettle, by feed pipe 2, alumina aqueous slurry is added to the inside of reaction kettle body 1, while cooperating with other mixed materials to mix slurry, the inside of reaction kettle body 1 is provided with heating device, because reaction kettle body 1 and its heating device are known technology, and the person skilled in the art can and should be clear its specific function and structure, the utility model is not improved, so here do not make superfluous words, the top of reaction kettle body 1 is fixedly connected with top shell 5, the top of top shell 5 is fixedly connected with motor 6, motor 6 is powered by external power supply by wire, the output of motor 6 is fixedly connected with rotating shaft 7, the outside of rotating shaft 7 is rotatably connected with the inside of top shell 5, the outside of rotating shaft 7 is fixedly connected with first bevel gear 8, the output of motor 6 drives rotating shaft 7 to rotate clockwise in the inside of top shell 5, while rotating shaft 7 also rotates in the inside of reaction kettle body 1, so that rotating shaft 7 will drive mixing rod 13 to rotate and agitate and mix the material in the inside of reaction kettle body 1 clockwise;

[0031] The inside of top shell 5 is fixedly connected with support rod 9, the outside of support rod 9 is rotatably connected with second bevel gear 10, the outside of second bevel gear 10 is engaged with the outside of first bevel gear 8, first bevel gear 8 is driven by rotating shaft 7 to rotate clockwise, so that first bevel gear 8 will drive second bevel gear 10 to rotate clockwise synchronously, at this time, second bevel gear 10 will drive third bevel gear 12 to rotate counterclockwise, so that third bevel gear 12 drives reverse rotating drum 11 to rotate counterclockwise in the inside of reaction kettle body 1;

[0032] The outside of rotating shaft 7 is provided with reverse rotating drum 11, the outside of reverse rotating drum 11 is rotatably connected with the inside of reaction kettle body 1, the outside of reverse rotating drum 11 is fixedly connected with third bevel gear 12, the outside of third bevel gear 12 is engaged with the outside of second bevel gear 10, it should be noted that, there is a certain gap between the outside of rotating shaft 7 and the inside of reverse rotating drum 11, so that rotating shaft 7 and reverse rotating drum 11 do not interfere with each other when rotating, while rotating shaft 7 drives the outside mixing rod 13 to rotate clockwise, reverse rotating drum 11 also drives the outside mixing rod 13 to rotate counterclockwise, so that the material above and below in the inside of reaction kettle body 1 is agitated in opposite directions, so that the working efficiency when mixing material of reaction kettle can be improved.

[0033] The rotating shaft 7 and the outer part of the reverse rotating drum 11 are fixedly connected with four mixing rods 13, and one end of the eight mixing rods 13 is fixedly connected with four arc corner scrapers 14. It should be noted that the reaction kettle is heated by the heating device inside the kettle body, and then the material in the kettle is heated. If the material adheres to the inner wall of the reaction kettle during mixing, the heating efficiency of the material will be affected. At the same time, if the material adheres to the bottom or top of the reaction kettle, the uniformity of the material mixing will also be affected, thereby affecting the working quality of the reaction kettle. Therefore, when the mixing rod 13 rotates, the arc corner scraper 14 is driven to rotate to scrape off the adhering material on the inner wall and the bottom and the top of the reaction kettle body 1, which is beneficial to improve the working quality of the reaction kettle.

[0034] The outer part of two mixing rods 13 is rotatably connected with a positioning ring 15. The positioning ring 15 does not displace when rotating at a specific position of the mixing rod 13. The outer part of the positioning ring 15 is fixedly connected with two first turbulence rods 16. When the material is mixed and flows, the first turbulence rod 16 is driven to rotate outside the mixing rod 13 in cooperation with the positioning ring 15. At the same time, the second turbulence rod 17 also rotates under the influence of the material flow. The rotation of the first turbulence rod 16 and the second turbulence rod 17 generates turbulence in the material mixing flow, breaks the original flow state, and enables the materials to exchange and mix more fully during mixing, thereby improving the uniformity of mixing.

[0035] The outer part of the first turbulence rod 16 is rotatably connected with the second turbulence rod 17.

[0036] The bottom of the reaction kettle body 1 is fixedly connected with a discharge pipe 2. The discharge pipe 2, the feed pipe 3 and the exhaust pipe 4 are all provided with valves inside. The specific functions and structures of the valves are very mature at present, and those skilled in the art can and should be clear about them, and thus no further description is given herein. The top of the reaction kettle body 1 is fixedly connected with a feed pipe 3. The top of the reaction kettle body 1 is fixedly connected with an exhaust pipe 4. The alumina aqueous slurry is added into the inside of the reaction kettle body 1 through the feed pipe 3 for mixing. After the material mixing work is completed, the mixed material is discharged through the discharge pipe 2. The gas generated during the material mixing is discharged through the exhaust pipe 4, so as to avoid the accumulation of gas in the kettle and affect the material mixing reaction.

[0037] A reaction kettle mixing assembly, the working principle is as follows:

[0038] Firstly, when the reaction kettle is used, the alumina aqueous slurry is added into the inside of the reaction kettle body 1 through the feed pipe 2, and other mixed materials are added at the same time to mix the slurry. The output end of the motor 6 drives the rotating shaft 7 to rotate clockwise in the inside of the top shell 5. At the same time, the rotating shaft 7 also rotates in the inside of the reaction kettle body 1, so that the rotating shaft 7 drives the mixing rod 13 to rotate to stir and mix the materials in the inside of the reaction kettle body 1 clockwise.

[0039] Secondly, the first bevel gear 8 is driven to rotate clockwise by the rotating shaft 7, so that the first bevel gear 8 drives the second bevel gear 10 to rotate clockwise synchronously, at this time, the second bevel gear 10 drives the third bevel gear 12 to rotate counterclockwise, and then the third bevel gear 12 drives the reverse rotating drum 11 to rotate counterclockwise inside the reaction kettle body 1, so that the materials above and below inside the reaction kettle body 1 are stirred in opposite directions, which can improve the working efficiency when the reaction kettle mixes materials;

[0040] And the arc angle scraper 14 is driven to rotate by the mixing rod 13, so that the arc angle scraper 14 scrapes the inner wall, top and bottom of the reaction kettle body 1, prevents the materials from adhering to the inner wall and bottom, and drives the first spoiler rod 16 to rotate outside the mixing rod 13 in cooperation with the positioning ring 15 when the materials flow, and the second spoiler rod 17 also rotates under the influence of the material flow, the rotation of the first spoiler rod 16 and the second spoiler rod 17 generates turbulence to the material flow, breaks the original flow state, so that the materials can be more fully exchanged and mixed when mixed, thereby improving the uniformity of mixing;

[0041] Finally, the exhaust pipe 4 can be used to exhaust the gas generated during the mixing of the materials, so as to avoid the accumulation of the gas in the kettle and affect the mixing reaction of the materials, and the mixed materials can be discharged through the discharge pipe 2.

[0042] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, should be included in the protection scope of the present application.
