Title: Conveyor belt support grid, esp. for filtration - is one piece synthetic material with walls aligned obliquely
Inventor: OOSTEN J VAN
IPC: B01D33/04
Filed: 1977-05-26
Abstract: In an installation incorporating an endless belt, esp. a permeable belt for filtration purposes, a supporting surface over which part of the belt slides is provided. The support comprises a grid layout, the openings of which are defined by walls extending across the surface of the belt so that they subtend an angle to the line of motion of the belt. The outer edges of the support grid have a saw tooth or waveform profile, so that a pair of supports laid side by side form openings corresponding to those down the middle of the support. The wall sections of the supporting details are formed by strips subtending an angle to its long axis, and the detail is of greater length in the direction of motion of the belt, than it is across the belt. On the reverse side of the supporting grid, there are props. uniformly spaced out for supporting the grid and these are positioned at the intersections of the walls of the grid. Lugs project from the sides of the grid for supporting one laid alongside it and the lugs of the separate grids are offset to each. Wear of the belt due to the narrow slit in the direction of motion, between neighbouring supports, into which the belts tend to sag, is eliminated. The supports are easily produced by extrusion techniques from synthetic materials capable of withstanding corrosive substances.
