Abstract

Przedmiotem zgłoszenia jest samoczyszcząca zmechanizowana krata, zwłaszcza do oczyszczania ścieków, składająca się z rusztu filtracyjnego (1) w postaci układu równoległych prętów, zbiornika zanieczyszczeń (5), układu cięgien napędowych (2) prowadzonych wzdłuż bocznych krawędzi kraty, po stronie cieczy oczyszczonej i napędzanych kołami wału napędowego (4) oraz zespołu przesuwnych zgarniaczy (3) w kształcie grzebieni, których zęby są wsunięte między pręty rusztu filtracyjnego (1) i wystają po jego przeciwnej stronie, charakteryzuje się tym, że długość zębów zgarniaczy zanieczyszczeń (3) jest zmienna lub kąt odchylenia zębów zgarniaczy zanieczyszczeń (3) względem płaszczyzny rusztu filtracyjnego (1) jest zmienny.The subject of the application is a self-cleaning mechanized grate, especially for sewage treatment, consisting of a filter grate (1) in the form of a system of parallel bars, a dirt tank (5), a system of drive rods (2) guided along the side edges of the grate, on the side of the purified liquid and driven by the wheels of the drive shaft (4), and a set of sliding scrapers (3) in the form of combs, the teeth of which are inserted between the bars of the filter grate (1) and protrude on its opposite side, characterized in that the length of the teeth of the dirt scrapers (3) is variable or the angle of inclination of the teeth of the dirt scrapers (3) relative to the plane of the filter grate (1) is variable.
