The invention discloses a slurry metal cleaning device used for papermaking. The invention includes a base, a support plate, a first electrical machine, a driving wheel, a driven wheel, a belt, a first rotating shaft, a first bearing, two take-up reels, a magnetic iron sheet, and haulage ropes. The support plate is fixedly connected with the upper surface of the base, the first electrical machineis connected with the right side surface of the support plate, an output shaft of the first electrical machine is fixedly connected with the left side surface of the driving wheel, the driving wheel is connected with the driven wheel through the belt, the left side surface of the driven wheel is fixedly connected with the right end of the first rotating shaft, the outer wall of the first rotatingshaft is sleeved by the first bearing, the first bearing is clamped with the right side surface of the support plate, and the outer wall of the first rotating shaft is fixedly connected with two take-up reels. The cleaning for the metal chip in the slurry is realized through the common effect of the first electrical machine, the driving wheel, the belt, the driven wheel, the first rotating shaft,the magnetic iron sheet, the take-up reels and the haulage ropes, so that the metal chip and slurry are separated, the clean slurry is obtained, thereby the quality of the toilet paper is guaranteed,and the health of people is guaranteed.
