Wastewater treatment screener HIDRORAKE ®

for hydraulic applicationsfixedsolid/liquid

Characteristics: In order to try to solve the separation problems, an Automatic Screen System with the following advantages was developed: - Without gears - Without chains - Without cushions - Without mechanical torque switches. - Without drivers - Without wheels no rods - Without fixed guides for the brush In year 1983 the two first screens with these requirements were assembled in the Vilanova and Geltrú E.D.A.R. for our client Dragados Construcciones, S.A. From that date on, we have been constructing them, and at the same time our technical department has been introducing improvements that have increased its performance and dependability and reduced its maintenance. Basically, the operation idea of the HIDRORAKE ® screen, is to reproduce by means of a headstock and two oleo hydraulic cylinders, the movements that a person would do to clean a screen with a rake, which would be, - Raise the rake, and being in upwards position, put it down to the bottom of the channel - Nail the rake in the screen and pull it upwards, raising the solids retained in the screen - Discharge the retained solids in a container, endless carrier, band, basket.
