[0032] Working principle: Before using this type of mixer for producing fused magnesia raw materials, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5 As shown, in the process of producing fused magnesia, raw materials can be fed into the feed hopper 102. A drive motor is installed on the feed hopper 102 to drive the rotation of the crushing roller 103 on one side, so that the raw materials can be crushed. The crushed raw materials can enter the collection hopper 204. At this time, the servo motor 201 is started to drive the rotating shaft 202 to rotate. The rotation of the rotating shaft 202 can drive the rotating tube 205 to rotate. The crushed material is temporarily stored in the collection hopper 204. When the particle size of the material meets the requirements after crushing, it can enter the rotating tube 205 through the filter hopper 207. The rotating tube 205 can drive the rotating rod 209 to rotate, so that the rotating frame 210 rotates. The material adhering to the outside of the filter hopper 207 can be rotated by the fixed rod 212 and the interlacing rod. 211 creates an interlaced dispersion to prevent material clumping and increase mixing time. The material enters the feeding pipe 220 through the rotating pipe 205 and the telescopic pipe 219. Raw materials are added through the feeding pipe 220. The rotating pipe 205 can add materials in a circumferential manner. When the rotating shaft 202 drives the fixed plate 203 to rotate, the driven gear 217 can drive the rotating shaft 214 to rotate through meshing with the internal gear ring 218. The rotating shaft 214 rotates on its own axis during the circumferential rotation. The stirring rod 215 can stir the material. This avoids stirring the sticky material during the crushing and mixing of fused magnesia, expands the feeding range of raw materials, and improves the working efficiency of raw material stirring.

[0033] During rotation, the rotating shaft 214 can drive the wheel cam 213 to rotate. The cam 213 can push the connecting frame 231 to move the movable rod 223. During the movement of the movable rod 223, the fixed block 227 can drive the sliding rod 228 to slide on the connecting block 229, and can stretch the telescopic spring 230. The movement of the movable rod 223 can drive the support rod 221 to rotate through the meshing of the rack 225 and the mounting gear 226, which in turn can drive the feeding pipe 220 to rotate. When the cam 213 rotates away from the connecting frame 231, the movable rod 223 is reset under the action of the telescopic spring 230, so that the support rod 221 can be reset to rotate. When the rotating shaft 202 rotates, the feeding pipe 220 can swing back and forth, which can further expand the feeding range, ensure the uniformity of feeding, and improve the mixing efficiency.

[0034] Although the utility model has been explained in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
