HORIZONTAL SAND SEPARATOR WITH HYDROMECHANICAL SYSTEM FOR REMOVING SEDIMENT

摘要

The invention relates to the purification of water from mechanical impurities, to a horizontal sand catcher with a hydromechanical sludge removal system, it allows to increase the efficiency and reliability of its operation, reduce the metal consumption and improve the quality of the sediment. The essence of the invention is that in the horizontal sand-catcher, the upper edges of the plates 7 of the grate 6, having the form of a grating bottom, are bent down and located above the surface of the adjacent plates with a gap. In addition, the angle of inclination of the plates 7 to the horizontal plane is made variable, increasing from the entrance to the exit of the sand trap. 1 hp ff, 3 ill.
