elevator sieve - sertel nvb


PRINCIPLE

The SERTEL NVB screen is designed to be installed in a channel or in a pit, works without preliminary rising of water.

In its lower part, a flat grid, with a 75° inclination, stops the particles larger than the opening slot present in the flow, These particles are continuously scraped towards an outlet chute.

The scrapers are made of stainless steel brushes for slots lower than 6 mm. For 6 mm slots and higher we use polyethylene or stainless steel combs.



DESIGN FEATURES

The SERTEL NVB sieves are composed of the following features :

A housing made of stainless steel with 3 mm thick sheet, assembled mainly by bolts.

The removable filtering grid, following the kind of slot, consists of triangular section wires for 6 mm slot maximum, this profile allowing an optimal hydrodynamic flow. For larger slots it is made of 5 mm stainless steel bars, set on edge.

The standard length of the grid is one meter, but can be modified on request. The width of the grid depends on the flow rate, slot and water draught in front of the grid.

The length is available from 1.5 to 10 meters, by 500mm steps. The width is calculated according to the following flow rates.

Scraping system includes: an axis and two stainless steel bearings, two stainless steel chains with DELRIN rollers, between which supports are fixed carrying the metal combs or brushes.

The absence of a lower axis leaves a totally open way towards the grid.
