Efficient lithium bicarbonate impurity removal device

The utility model belongs to the technical field of calcium carbonate production, and particularly relates to an efficient lithium bicarbonate impurity removal device, which solves the problems of low impurity removal efficiency and poor practicability in the prior art, and comprises a shell, the top of the shell is fixedly connected with a mounting frame through screws, and a motor is mounted on the shell; the output end of the motor is fixedly connected with a rotating shaft through a coupler, the rotating shaft is coaxially arranged, the other end of the rotating shaft is fixedly connected with a guide rod through a screw, the other end of the guide rod is movably hinged to a supporting rod, and the other end of the supporting rod is fixedly connected with a transverse plate through a screw. The motor drives the sliding block fixedly connected with the connecting rod to move, materials in the shell are screened out, fine materials fall to the upper filter screen, and materials which cannot be filtered are
