The curved screen SERCOURB is used in the treatment of wastewater, urban effluents (waste water treatment plant & unloading of water cleaning trucks / emptying materials), industrial effluents (food industry: canneries, slaughterhouses, dairies / cheese dairies, fruit washing and vegetables, fish industry – chemistry / pharmacy – mechanical industry & paper industry – agricultural sector: breeding) and in processes.
Chemistry - Pharmacy
The curved screen SERCOURB is part of run-of-river screens or sieves. Installed in a channel, its curved grid stops the particles larger than the opening slot, contained in the effluent. These particles are then scraped and raised by a rotating double arm rake towards the discharge chute, located on the upper part of the grid. The rotating double arm rake is equipped with a flexible flap on one side and a comb on the other.
It is easy to install and requires little maintenance. It can operate without monitoring.Faced with the increasing difficulties of operating screw screens for the screening of sewage, Serinol offers the principle of the curved screen SERCOURB as an alternative to this technology. Rustic, economical and requiring little maintenance, the curved screen SERCOURB, integrated into a stainless steel box with a complete cover, allows a direct connection to the hydro-cleaning truck. (See the PACK MDM notice)
The curved screen SERCOURB consists of the following elements:
A folded sheet metal box, made of 304 L stainless steel, 3 mm thick. Surrounded by a tubular frame, it allows the equipment to be placed in a concrete channel.
A curved and removable filtering grid, composed for the “sieve” version of triangular section wires, until 6 mm slots. Further, in the “screen” version, the grid is made of 6×20 mm section stainless steel bars, laser-cut set on edge.
Its width is defined according to the flow rate, the slot and the draught (water height in front of the grid).
The bending radius of the grid is adapted to the channel depth.
A scraping system includes:
A double arm mounted on an axis, maintained by two self-aligned stainless steel bearings:
On one of the arms, there is a rubber flap for a coarse scraping of the matters accumulated on the grid. Only large matters will be taken up.
On the other arm extremity, a stainless steel comb (or a stainless steel wires brush for “sieve” version), mounted on a retractable support. The comb/brush ensures an optimal unclogging of the grid.
The articulation equipped with a return gas-spring avoids the risk of the scraping system blocking in case some big material is blocked between the bars of the grid.
A motor drives the arms in rotation.
A position sensor on the arm that stops the rotation once it is out of the water flow area.
The ejection system that pushes all matters present on the scraper or the flap towards the discharge chute.
