Description

Red mud separation sedimentation device Technical Field The utility model belongs to the technical field of gold treatment production, and particularly relates to a red mud separating and settling device. Background Red mud is an industrial solid waste discharged when alumina is extracted in the aluminum production industry, and is called red mud because of high iron oxide content and similar appearance to red mud. The mixed slurry containing red mud and sodium aluminate solution is obtained after bauxite is dissolved out, and the red mud and the solution are separated by sedimentation or filtration after dilution, so that the sodium aluminate solution required by seed crystal decomposition is obtained, and the sedimentation separation effect has important influence on the quality of a final product, the production cost and the economic benefit. The patent of publication number CN220159369U discloses "a red mud separation sedimentation device", relates to metallurgical production technical field, including the circular slot, the middle part fixedly connected with acceleration subassembly at circular slot top. Through the arrangement of the accelerating assembly, the cleaning assembly and the sedimentation assembly, mud is poured into the filter cone, then the red mud is filtered and sedimented through the filter cone, then the motor A drives the driving rod A to rotate, the stirring rod of the driving rod A rotates, the stirring blade is driven to stir the red mud, and then red mud sediment gathers solid red mud to the center under the effect of centrifugal force to accelerate red mud sediment filtration subsides, later when subside after the end B motor drive B actuating lever and rotate, later B actuating lever drive the revolving plate rotate, and the revolving plate rotates the scraper blade that drives both sides and rotates afterwards, and then scrapes the absorbing red mud of filter cone when the scraper blade rotates and remove. Although the red mud adsorbed on the inner side wall of the filter cone can be scraped off by the rotation of the scraping plate in the prior art, mud residue in the red mud is easy to enter and is blocked in the meshes of the filter cone after long-time use, and the meshes of the filter cone cannot be dredged by the scraping plate, so that the mud residue can be left in the meshes of the filter cone to cause blocking, thereby affecting the normal use of the separation sedimentation mechanism such as the filter cone, and the like, and therefore, the improvement is needed. Disclosure of utility model The utility model aims to solve the problems and provide a red mud separating and settling device.
