Description

Technical Field

[0001] The utility model belongs to the technical field of tailings processing, and specifically relates to tailings slurry mixing equipment. Background Art

[0002] Tailings are waste materials generated during mining, mineral extraction, construction sites, etc. They have different characteristics such as concentration and particle size and need to be slurried to facilitate subsequent disposal and utilization.

[0003] In the existing technology, tailings are usually sucked into a mixing tank, and then water or other mixing agents are added to the inside of the mixing tank to mix the tailings, convert the tailings into usable materials, and reduce the negative impact on the environment. Since the inside of the mixing tank needs to be continuously stirred to prevent the tailings from agglomerating, directly adding liquid into the mixing tank may cause liquid splashing. At the same time, directly adding liquid may cause uneven mixing. Secondly, when adding liquid directly, it may not be possible to form convection and stirring inside the mixing box, which greatly reduces the mixing effect.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0009] The end of the stirring rod away from the sleeve is fixedly connected to a stirring spring, and the end of the stirring spring away from the stirring rod is fixedly connected to a stirring block. By arranging the stirring spring and the stirring block, the tailings inside the slurry mixing tank are further stirred to prevent the tailings from agglomerating into lumps inside the slurry mixing tank.

[0010] The bottom of the connecting rod is fixedly connected to a bottom plate, the outer wall of the bottom plate is fixedly connected to a scraper, and the bottom plate is rotatably connected to the inner bottom wall of the slurry mixing tank. By arranging the bottom plate and the scraper, the tailings at the bottom of the slurry mixing tank are stirred, and the discharge of the tailings at the bottom of the slurry mixing tank is facilitated.

[0011] The bottom of the slurry mixing tank is fixedly connected with a discharge pipe, and a valve is fixedly connected to the discharge pipe. The discharge pipe and the valve are provided to facilitate the discharge of tailings after mixing in the slurry mixing tank.

[0014] Through the operation of the rotating motor, the shaft drives the large gear ring to rotate, the small gear ring rotates accordingly, the connecting rod drives the sleeve ring to rotate, and the stirring rod stirs the tailings inside the slurry mixing tank. Through the coordinated use of the stirring spring and the stirring block, the tailings inside the slurry mixing tank are further stirred, thereby preventing the tailings from agglomerating into lumps inside the slurry mixing tank and allowing the liquid formulation and the tailings to be quickly mixed.
