Central flow large diameter rotating drum filter

VTR1

CATEGORY WATER INTAKE
TYPOLOGY SCREENS


The VTR1 filter is particularly suitable for installation in intake channels for sea, lake or river water, deeper than 4-5 meters and for water to be used after filtration for cooling in industrial processes, desalination, potabilization and in other production processes in general.


The machine is essentially composed of: a sturdy cylindrical-shaped bearing structure stiffened by means of steel profiles arranged in a radial pattern, ideal for having a large free cylindrical surface which is at the same time very robust and able to withstand heavy loads such as rotation in water and the thrusts of the hydraulic flow; a series of filter panels bolted to the above structure and easily removable, each panel consists of a frame and a filtering screen in square mesh or perforated sheet metal; a rotating shaft supporting the entire structure; two sturdy supports mounted on the sides of the drum and equipped with special bearings lubricated for life for continuous operation even in water, appropriately sized to support the drum during rotation; a gearmotor with cylindrical gears for the rotation of the drum by means of a pinion which meshes with the rack; a counter-current washing bar of the filtering surface, from the inside to the outside, complete with high-pressure nozzles; a hopper for collecting the screened material and washing water; a sealing system consisting of gaskets mounted between the rotating drum and a fixed steel part mounted on the channel wall. Protection against overloads is guaranteed by standard dynamometric devices or, upon request, by electronic absorption limiters. Its simple design and fully automatic cleaning allow this filter to always guarantee high performance and reliability over time.


The water that arrives in the channel near the filter divides into two streams and enters the filter in an axial direction from both sides; the central front surface of the filter is closed and forces the flow itself to cross the cylindrical surface, made up of filter panels, from the inside out. The water recombines after filtration, crossing the entire immersed area of the drum and continues its motion along the downstream channel. The screened material held on the inside of the filter is pushed into the two hoppers by the washing water which is sprayed from the outside towards the inside.
