Continuous washing of fresh concrete blocks - without interrupting course of production, involves frame with multiple spray heads

摘要

The apparatus for continuously washing visible surfaces of fresh concrete blocks comprises a pallet conveyor about which is mounted a frame which consists of pipes which conduct water under pressure and which are disposed transversely to the direction of conveyal and are at a given distance from the visible surfaces of the blocks. On the pipe walls facing the blocks are nozzles mounted one behind the other in the longitudinal direction of the pipe. Each pipe includes a water discharge regulator comprising a pressure-reducing valve and is rotatable about its axis with its ends connected to the frame by a connector.
