Toothformed lattice plate

Abstract

The invention built up of a movable lattice plate and a fixed lattice plate for the step type filter, wherein the horizontal step shaped plate is made slightly downward to the flowing direction, and the step joint face connecting the distance between each step shaped plate is made in roundly dented form leading to the toothformed lattice plate, by which application a step type filter is built up, and such a step type filter formed could operate even by an setting angle nearing a steep inclination (near 90°) so that may collect and discharge the solid material effectively despite its application to the deep waterway.

What is claimed is:  
     
         1 . The tooth formed lattice plate with the step face and step joint face applicable to the step type filter is characterized in that the step shaped plate is formed so as to maintain a slightly inward inclined angle toward the flowing direction, the step joint face roundly dented.
