Document Type and Number:
Japanese Patent JP3548938
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To quickly and reliably discharge cleaning air in the lower part of a lower water-collecting apparatus by installing a gas discharging pipe to discharge air remaining in the lower part of the lower water-collecting apparatus after air cleaning in a manner that the uppermost part of the inside of the pipe is in the same plane as the lower face of the lower water-collecting part or higher than the lower face. SOLUTION: An air pipe 10 is so installed as to be in the same plane as the uppermost part of a treated water discharging part 6, that is the uppermost face of a guide groove 11 for air discharge installed in the lower face of a lower water-collecting apparatus 2 and air in the treated water discharging part 6 is discharged through the air pipe 10. Consequently, air far from the air pipe 10 can flow toward the air pipe 10 through the guide groove 11 for air discharge, so that air in the lower part of the lower water-collecting apparatus 2 can be quickly and reliable discharged. As a result, air is prevented from jetting together with cleaning water to a filter material 5, so that the filter 5 is prevented from being blown up and flowing out of a trough 8.
