Cleaning apparatus for filtration layer in seawater infiltration intake
[Problem] To provide a cleaning apparatus suitable for removing clogging substances trapped on the surface layer of the sand filtration layer. [Solution] A cleaning apparatus (11) provided with drive wheels (12) as a movement means for moving over the surface of the sand filtration layer. A pump (13) and a jet nozzle (14) are provided as a stirring means for stirring the necessary depth of the surface layer of the sand filtration layer and stirring up the clogging substances along with filter sand into the seawater inside a turbid water suction pit (20). A perforated emulsified water suction tube (15), a pump (16), an ejector (17), and a dilute emulsified water-discharging tube (18) are provided as a suction-discharging means for drawing in the turbid water stirred up into the seawater inside the turbid water suction pit (20) by the stirring means and discharging same to the outside of the turbid water suction pit (20). [Effect] The invention prevents clogging by timely cleaning of the sand filtration layer and can maintain high seawater infiltration rates. Because turbid water containing clogging substances, which is stirred up into the turbid water suction pit, is drawn up and discharged outside of the system, effects on the surrounding environment are also reduced.
