Description

Technical Field

[0001] The utility model relates to the technical field of mixers, and more specifically, the utility model relates to a cold slag double-shaft mixer. Background Art

[0002] Cold slag refers to the slag material generated in the high-temperature smelting or production process and processed by rapid cooling. The cold slag double-shaft mixer is a mechanical device specifically used to process cold slag (i.e., the high-temperature slag material after cooling treatment). It uses a double-shaft stirring method to mix, crush, or convey the cold slag.

[0003] There are stirring dead angles at the gaps between the existing fan blades and the mixing tank. At the same time, when the fixing plate is raised, the oblique thrust of the two connecting rods is not only laborious but also the stability of the mixing tank is poor.

[0004] After retrieval, the Chinese patent with the application number CN202221403277.5 discloses a double-shaft mixer. When in use, the material is poured into the mixing cylinder, and the first motor drives one rotating shaft to rotate. The two rotating shafts rotate in opposite directions driven by the first gear transmission pair. The two rotating shafts respectively drive the stirring rods fixedly connected thereto to mix and stir the material.

[0005] When the above double-shaft mixer is actually used, the existing double-shaft stirring rods have a single stirring, resulting in insufficient uniformity of the cold slag during the stirring process, which is not convenient for achieving full mixing of the material, affecting the overall stirring effect. At the same time, the cold slag is easily attached to the inner wall of the mixing barrel during the stirring process, thereby reducing the stirring efficiency. Summary of the Utility Model

When the first rotating rod rotates, it drives the two support rods to rotate at the same time, so that the two support rods can drive the scraping plates to scrape the inner wall of the mixing barrel to prevent cold slag from adhering to the inner wall of the mixing barrel.

[0010] As a further description of the above technical solution: two sliding grooves are opened inside the mixing barrel, and a discharge pipe is communicated with the bottom end of the mixing barrel.
