AN ENVIRONMENTALLY FRIENDLY AND ENERGY EFFICIENT HIGH CONVERSION RARE EARTH CATALYST ROASTING DEVICE

The environment-friendly energy-saving high-conversion-rate rare earth catalyst roasting device comprises a device body, a roasting cavity of a circular-truncated-cone-shaped structure is formed in the device body, two turning cavities are symmetrically formed in the device body relative to the roasting cavity, and the inner top end of the roasting cavity is rotationally connected with a square shaft through a bearing; the upper end of the device body is fixedly connected with a supporting frame of a door-shaped structure. In the using process of the device, in the process that the motor drives the square shaft to drive the stirring rods to rotate, the cam rotates relative to the rolling piece, the rolling piece always abuts against and makes contact with the lower surface of the cam under the elastic force of the springs, the heights of all points of the cam in the circular track of rotation of the rolling piece are different, and under the action of the height difference, the pressing plate ascends and descends; under the action of the spring, the other stirring rods are unfolded and folded by taking the lowest stirring rod as a starting point, and the stirring form is changed, so that the stirring effect is improved.
