<p>The invention relates to a sand catcher comprising a deposition chamber ( 1 ) that is configured as a steel container with a cylindrical cross-section, traversed in a longitudinal direction. Said deposition chamber comprises air-supply nozzles ( 4 ) on one longitudinal side for generating a circulatory motion or the water transversally to the longitudinal direction of the deposition chamber ( 1 ) and a sand collection channel ( 3 ), located in the lower section, that runs in a longitudinal direction. A waste water inlet ( 6 ) for generating the circulatory motion of the water leads into the upper section of the deposition chamber ( 1 ), running transversally to said chamber. The air-supply nozzles ( 4 ) are provided on the side of the waste water inlet ( 6 ) below the latter ( 6 ).</p> |
