A SCRAPING DEVICE FOR BELT FILTER PRESS

摘要

A scraping device of a belt filter press in the present invention comprises a discharge drum, of which outer circumference is wound by filter belts and rotates; wire fixing tools which are installed respectively on the upper direction and the lower direction of the discharge drum; wires whose both ends are fixed and installed on the wire fixing tools formed respectively on the upper discharge drum and on the lower discharge drum to contact the surface of the filter belts wound on the discharge drum wherein the wire is diagonally installed under a certain angle which is formed from an axis crossed with a center axis of the discharge drum. Therefore, the scraping device of the belt filter press in the present invention enables the wires to be closely installed along with the curved line of the filter belt surrounding the outer circumference of the discharge drum and then to cut and to separate cake attached to the filter belt with regular pressure without large welding force.
