Description

Technical Field

[0001] The utility model relates to the technical field of casting material stirring equipment, in particular to a casting material processing stirring mechanism. Background Art

[0002] Castables, also known as refractory castables, are granular and powdery materials made of refractory materials with a certain amount of binder. They have high fluidity and are amorphous refractory materials formed by pouring. Refractory castables are a mixture of refractory aggregates, powders and binders. After adding water or other liquids, they are suitable for construction by pouring and vibration methods. They can also be prefabricated into prefabricated parts with specified shapes and sizes for the construction of industrial furnace linings. Compared with other amorphous refractory materials, castables have higher binder and moisture content and better fluidity, so they have a wider range of applications. Mixed castables need to be prepared when producing refractory bricks.

[0003] In order to improve the physical and chemical properties and construction performance of refractory castables, appropriate amounts of admixtures are often added, such as plasticizers, dispersants, accelerators, retarders, expanders, debonding and gelling agents, etc. Refractory castables are composed of three parts: binder, aggregate and admixture, and accelerators are sometimes added. Therefore, during use, different materials need to be mixed and then sent into a mixing box for uniform mixing. Existing refractory castables are generally stirred manually during batching, which results in uneven stirring and unstable quality, which is not conducive to improving the production efficiency of the enterprise. For this reason, China Patent Publication No. "CN210905888U", entitled "Automatic stirring device for amorphous refractory castable", proposes a solution, which can realize the automatic stirring function of amorphous refractory castable by setting a stirring mechanism, a first driving mechanism, a second driving mechanism and a pumping mechanism. At the same time, during the stirring process, the stirring blades on the solid rotating shaft and the hollow rotating shaft rotate in opposite directions for stirring, so that the castable in the stirring box produces a collision torrent, thereby achieving a better stirring and mixing effect. At the same time, the feeding pump and the feed port can be used to stir the castable for multiple cycles, so that the stirring effect is further improved.

[0004] Although the technical solution has achieved certain improvement in stirring effect, the above-mentioned stirring device only realizes mixing and stirring of the castable material by the relative counter-rotating stirring blades on the solid shaft and the hollow shaft. When the above-mentioned solid shaft rotates at the bottom of the mixing box, the hollow shaft rotates at the upper part, and the two rotate in opposite directions. The upper and lower layers of castable materials are stirred and mixed in layers in the mixing box. However, since the solid shaft and the hollow shaft are not in the same space, the upper and lower stirred castable materials are mixed in the same direction, and the upper and lower layers of castable materials flow in a single direction. The upper and lower layers of castable materials cannot be fully collided and mixed, resulting in uneven mixing effect of the castable materials stirred in layers in the mixing box. Therefore, the technical effect of this technical solution needs further study. Utility Model Content
