Abstract

PURPOSE: To greatly reduce the number of automatic valves in use and improve the reliability of equipment, by connecting a check valve and a soft piece feeding collector in series with each other to a sampling pump.
CONSTITUTION: A check valve 27 and a feeding collector 8 are coupled in series with each other on the discharge side of a sampling pump 3. In washing operation, the pump 3 is stopped, an automatic valve 22 is closed and another automatic valve 25 is open. At that time, still another automatic valve 24 is opened so that sponge balls 9 charged in the feeding collector 7 move to another collector 8. In that case, washing water is drained from an outlet port 13 through the valve 25. To recover the sponge balls to the collector 7, the pump 3 is driven after the valves 24, 25 are closed and another automatic valve 23 is opened.
