BAR SCREEN SYSTEM FOR SCREENING SOLID WASTE FROM A FLOWING LIQUID, USED FOR PRELIMINARY WASTE WATER TREATMENT

摘要

FIELD OF THE INVENTION The present invention relates to a slurry and sediment trap system with rakes for removing solids from flowing liquids, mainly for wastewater treatment, which is part of a grid system: a larger number of parallel grid bars (2), which are arranged in a substantially transverse directional direction of the flow direction of the flowing fluid in the direction of the flow of fluid. create grid spacing of a given width between themselves; a rake structure, which rakes the solids from the grid (2), and the rake structure comprises two chains (4) passed through the sprockets (5) and moving together with the rake structure, a motor (6) for driving the chain (4), which is a motor (6) coupled with an overload sensing device, also seen by a device capable of changing the direction of rotation of the sensor structure (6), is a scraping mechanism for unloading the stacked solids. The grid system according to the invention is configured such that the rake structure comprises a large number of rakes (3), the rake (3) is secured to the chains (4) by retaining the positions given on the chains (4), and the rake (3) is perpendicular to the grid rod. a current sensing device is connected to the drive motor (6) by the chain (4), which provides an overload signal to the rack (3) by measuring the current to change the direction of rotation of the motor (6). ŕ
