This utility model discloses a pulp impurity cleaning device for paper product production, relating to the field of paper product manufacturing technology. The utility model includes a housing, a backflush anti-clogging component, and an automatic impurity cleaning component. A filter screen is fixedly connected between the two sides of the inner cavity of the housing, and a discharge pipe is connected to the right side of the housing.
