Working principle and structural features of frame mixer

The frame mixer can be regarded as the deformation of the paddle mixer, which has strong structure and large amount of animal materials The gap between the frame agitator and the wall of the kettle is small, which is conducive to the heat transfer process It is often used for heat transfer, crystallization operation and the mixing of high viscosity liquid, high concentration slurry and settling slurry The working principle and structural characteristics of the frame mixer: the diameter of the frame mixer is large, generally 2 / 3-9 / 10 of the inner diameter of the reactor, 50-70r / min The gap between the frame stirrer and the reactor wall is small, which is conducive to the process of heat transfer When rotating rapidly, the liquid driven by the stirrer blade takes the static layer down from the reactor wall; when rotating slowly, the stirrer with scraper can produce good heat transfer The connection between the frame mixer and the mixing shaft is similar to the paddle type, that is, one end of the impeller and the mixing shaft is made into a semicircle shaft ring, and then two semicircle rings of the blades on both sides are clamped on the mixing shaft with bolts, and the blades and the mixing shaft are fixed with the through shaft bolts Due to the large size of the impeller, in order to facilitate the installation and removal, most of the blades are connected by bolts Impellers are mostly made of flat steel and angle steel In order to improve the strength of impellers, reinforced steel plates can also be used The mixing shaft is connected with the rung and the vertical bar by assembly or welding When the mixing shaft is driven and rotated by the decelerating motor, the animal material can flow horizontally and circularly at different heights The rung and the vertical bar can effectively divide the material to achieve the effect of forced mixing and dispersion.
