[0002] Pre-firing of magnetic materials refers to materials that have been pre-firing during the production process of magnetic materials. It is the precursor of magnetic materials, and after subsequent processing and treatment, it can be made into various magnetic materials, such as permanent ferrite, soft ferrite, NdFeB permanent magnet, etc. There are two processing methods for the pre-firing of magnetic materials: dry grinding and wet grinding. When the raw materials are processed by wet grinding, the raw materials need to be ground into slurry, and then the slurry is stirred and mixed. However, when the existing stirring and mixing device is used to mix the slurry, the stirring and mixing method is relatively simple, and the mixing and stirring of the slurry is not uniform enough, which affects the product quality when the slurry is pre-firing later. To this end, we propose a stirring mixer for pre-firing magnetic materials. Utility Model Content

The mixing tank body 1 is used to stir and mix the slurry of the pre-sintered magnetic material after wet grinding. The side walls of the mixing tank body 1 are symmetrically fixedly mounted with a feed pipe 3 on the left and right sides. The feed pipe 3 is used to supply the raw materials to be mixed into the mixing tank body 1. A first solenoid valve 4 is embedded in the feed pipe 3.

The discharge pipe 5 is used to transport the materials after mixing in the mixing tank body 1. A second solenoid valve 6 is embedded in the discharge pipe 5, and the second solenoid valve 6 controls the opening and closing of the discharge pipe 5. The first solenoid valve 4 and the second solenoid valve 6 are electrically connected to an external power supply and an external controller respectively, and their opening and closing are controlled by the external controller.

[0019] A first mixing mechanism 7 is fixedly installed on the top of the mixing tank body 1, and a second mixing mechanism 8 is fixedly installed on the bottom of the mixing tank body 1. During use, the slurry in the mixing tank body 1 is fully stirred and mixed by the first mixing mechanism 7 and the second mixing mechanism 8 moving in different directions respectively, thereby improving the uniformity of mixing of the slurry in the mixing tank body 1.

[0020] like Figure 2 As shown in, the first mixing mechanism 7 includes a first motor 71, the output end of the first motor 71 is fixedly connected to an upper fixing frame 75 that penetrates the inner cavity of the mixing tank body 1 through a coupling, and the side wall of the upper fixing frame 75 is fixedly connected to an external stirring frame 73 through a first connecting shaft 72. The number of the external stirring frames 73 is at least four, and the four external stirring frames 73 are evenly distributed in a circle at the center of the upper fixing frame 75. The first motor 71 is electrically connected to an external power supply, and the rotation direction of the output end of the first motor 71 is clockwise. The upper fixing frame 75 and the external stirring frame 73 are driven to rotate in the clockwise direction by the first motor 71, and the external stirring frame 73 is in contact with the side wall of the inner cavity of the mixing tank body 1 to prevent the slurry to be mixed from remaining on the inner wall of the mixing tank body 1;

The internal stirring frames 85 are hexagonal, and the number of the internal stirring frames 85 is three groups, and the internal stirring frames 85 of each group are symmetrically distributed in the upper and lower parts. A second connecting shaft 86 is fixedly connected between the internal stirring frames 85 of each group, and the stability of the connection between the internal stirring frames 85 of each group is improved by adding the second connecting shaft 86. The rotation direction of the second motor 82 is counterclockwise. The rotation of the rotating shaft 83 is driven by the second motor 82, so that the internal stirring frame 85 rotates in the counterclockwise direction, and the internal stirring frame 85 cooperates with the external stirring frame 73 to complete the uniform mixing and stirring of the slurry in the mixing tank body 1.

[0023] Working principle: During use, the device will feed the slurry of the magnetic material produced after wet grinding into the mixing tank body 1 from the feed pipes 3 on both sides. After turning on the device, the first motor 71 and the second motor 82 in the device will drive the outer stirring frame 73 and the inner stirring frame 85 to move in different directions respectively.

After the stirring and mixing is completed, the slurry is transported to the next process through the discharge pipe 5.
