Scraper type concentrator

The utility model relates to a scraper type concentrator, for mainly solving the technical problems that a rotating shaft is long and the bottom end is easy to swing when the rotating shaft rotates. The concentrator is characterized in that a bearing is mounted at the lower end of the rotating shaft; the bearing is fixed on a bearing seat; and the bearing seat is mounted on a three-foot support rack which is fixed at the bottom of a tank body. The concentrator has the beneficial effects that as the bearing is mounted at the bottom end of the rotating shaft, the bearing is fixed on the bearing seat, and meanwhile the bearing seat is fixed through the three-foot support rack which is fixed at the bottom of the tank body, the bottom end of the rotating shaft is rotationally fixed inside the tank body, the bottom end of the rotating shaft does not swing when the rotating shaft is driven to rotate and stir by a motor, a scraper is effectively prevented from being collided with the inner wall of the tank body, and
