Device for shot-blasting of discharge water containing basins, esp. rain-basins electro-motor containing rotary drive arranged inside of basin and gas tight due to hood surrounding base of basin

摘要

The device comprises of at least one shot-blaster that has a discharge water suction pump and fed jet pipe (17), as well as means of at least one electro-motor (39) containing rotary drive (37) that is rotatably built. A section of the rotary drive is at least arranged inside of the basin (3), and is gas-tight by an open hood (47) surrounding the basin base (5).The electro-motor may be arranged on the upper-half of the jet pipe.The shape of the hood of the enclosed space may be smaller in the region of the electro-motor than in the under-lying region
