PURPOSE: A drive device of a scum screen is provided to efficiently remove impurities from a scum screen using a rake coupled to a transfer chain. CONSTITUTION: A drive device of a scum screen comprises first and second inner guide brackets(130,140), first and second guide protrusions(136,146), an outer guide bracket(150), and a third guide protrusion(156). The first and second inner guide brackets are installed on the inner surface of a vertical frame(102). The first and second guide protrusions are integrally protruded from the inner surfaces of the first and second inner guide brackets. The outer guide bracket is integrally installed on the inner surface of the vertical frame to be separated from the second inner guide bracket. The third guide protrusion is integrally protruded from the outer surface of the outer guide bracket. The first, second, and third guide protrusions are simultaneously inserted into chain grooves of a transfer chain(120) to prevent the transfer chain from being separated from a rake. |
