Patent ID: 8500997

Claim:
A screening grid for discharging solids from a liquid flow, the grid comprising a driveable screening strip that can be inserted into the liquid flow and comprising two lateral link chains, carrying rods extending between the link chains, and, screening links comprising two bearing orifice portions connected by a center portion, each bearing orifice portion comprising a respective bearing orifice having an orifice axis, and wherein, for each screening link, each of the two bearing orifice portions is thicker in a direction of the orifice axis of their respective bearing orifices than the center portion connecting the two bearing orifice portions, hooks extending non-parallel to the center portion on at least some of the screening links, the screening links being divided into groups of adjacent screening links, each group of screening links being arranged on two of the carrying rods such that the two carrying rods extend through the bearing orifices of the two bearing orifice portions, and each group of screening links being arranged on the two carrying rods independent of a preceding and a subsequent group of screening links and extending in a direction of the group between the two carrying rods, a projecting part on each of the screening links, all the screening links in each group of screening links having projecting parts on only one end of the screening links, the projecting parts extending in the group direction beyond only one of the two bearing orifice portions without overlapping with projecting parts of any adjacent group of screening links, each of the two bearing orifice portions on each screening link being thicker in a direction of the orifice axis of their respective bearing orifices than the projecting part of the link.
