Technical Specs
Description
VFR Fine Belt Screens are used for fine screening of waste water. They are designed for in-channel installation. They consist of a set of filtering steps manufactured from perforated plate media which are moved by two chains equipped with chain stretcher, as well as anti-friction and anti-noise sliding blocks.
Function
Solids screened from waste water are conveyed by the filtering belt to the outlet on top of the screen. The arrangement of the filter elements forms a “step belt” which ensures that screenings are picked up and easily removed. The screen is equipped with a chute in front of the filtering belt to avoid clogging.
A double cleaning system composed of a motorised roller brush equipped with synthetic bristles and of a washing bar cleans the filter elements. The chains are moved by sprockets fitted on a drive shaft that is connected to the gear reducer. The latter has to be equipped with a torque limit switch.
