The utility model belongs to the field of
digestion tanks and discloses a heatable
digestion tank which comprises a tank body, an interlayer channel is arranged on the side wall of the tank body, and a top cover is arranged at the top of the tank body; a hot water boiler; the rotating shaft is rotationally connected with the top cover, and multiple groups of stirring blades are arranged on the rotating shaft at intervals; the driving mechanism is mounted on the top cover and used for driving the rotating shaft to rotate; and a connecting plate is fixed to the end of the scraper, a connecting block is fixed to the end of the connecting plate, the rotating shaft is sleeved with the connecting block, and the scraper abuts against the inner wall of the tank body in a sliding mode. The scraping plate and the rotating shaft are connected through the connecting plate and the connecting block, so that the scraping plate can rotate along with rotation of the rotating shaft, the wall in the tank body is scraped and swept through the vertically-arranged long scraping plate, the scraping and sweeping range of the scraping plate is larger, and meanwhile through the arrangement of the multiple sets of stirring blades, the stirring efficiency is improved. Furthermore, a good stirring effect on raw materials at different depths can be achieved, and a scraping and sweeping effect on the side wall of the tank body can be achieved.
