| 摘要 |
The present invention relates to a residual water discharge apparatus of an anti-freezing ship block discharging residual water from a ship block. The present invention comprises: a base unit installed in a floor of the ship block and having a residual water inlet in a lower portion thereof; an ejecting unit installed in the upper portion of the base unit to provide a suction force by a compressed air to discharge the residual water; a residual water discharge unit connected to the upper portion of the ejecting unit and having a discharge passage discharging the residual water to the outside; a heating unit installed in an outer circumference of the residual water discharge unit and heating the residual water discharge unit to prevent the residual water discharged through the residual water discharge unit from freezing; and a compressed air injection unit connected to the ejecting unit to supply the compressed air to the ejecting unit. Therefore, the heating unit is installed in the residual water discharge unit in order to prevent, in advance, the residual water from freezing when the residual water is discharged and to melt the residual water frozen in the residual water discharge unit. |
