Abstract

The utility model relates to the technical field of material throwing devices, and discloses a material throwing device for a thickener, which comprises a throwing tank and a thickener, the feeding tank is a circular barrel with a circular opening at the lower end, and the feeding tank is fixedly arranged at the center of the thickener. According to the intelligent switching device, intelligent switching of mixing and cleaning functions is realized through the linkage structure of the movable disc, the scraping plate and the rotary column. When the rotating motor drives the rotating column to rotate, the movable disc drives the connecting block and the scraping plate to synchronously rotate to form stirring paddles, the mixing flow state of the flocculant and the slurry is forcefully dispersed, after the mixing is completed, the telescopic device pushes the connecting ring to move upwards, the movable disc drives the limiting block to ascend along the sliding groove, the scraping plate is forced to transversely expand outwards to cling to the inner wall of the feeding tank, and residues are automatically scraped in the rotating process. The design realizes the switching of the mixing-cleaning modes through a single driving source, so that the dispersion uniformity of the flocculant is improved, and the efficiency loss caused by the traditional manual slag removal is avoided.
