SBS telescopic pipe decanter

characteristic

Simple construction and easy maintenance; No power required, relying on buoyancy and self weight for lifting and lowering; Adjustable drainage volume and easy operation; Easy to achieve automatic control; The floating head rises during aeration to prevent sludge from flowing into the drainage pipe.

Working principle

The water decanter consists of a floating water head, a specially designed drainage telescopic hose, a drainage bend, a control solenoid valve, and a gas hose. When drainage is required (usually at the highest water level), the intake solenoid valve will automatically close, the exhaust solenoid valve will automatically open, and the air in the floating decanting head annular air chamber will be discharged. The floating head will sink and submerge the four inlet ports, and drainage will begin. The drainage volume per unit time can be adjusted with adjusting bolts within the drainage volume to control the drainage time. The drainage enters the expansion pipe and drainage bend pipe through the center pipe of the floating head and is discharged outside the pool. The floating head descends with the decrease of water level. The expansion hose gradually compresses, and when it reaches the lowest water level, the water level signal is sent out. The exhaust solenoid valve automatically closes. The intake solenoid valve automatically opens, and compressed air (pressure ≮ 5kPa) is introduced into the annular air chamber of the floating head. The floating head rises, and the inlet leaves the water surface, stopping the drainage. Excess air is discharged from the exhaust pipe, and the floating head rises with the increase of water level in the pool until it reaches the highest position, entering the next cycle.

The metal components of the decanter are made of stainless steel, except for the drainage bend which is made of carbon steel. Compressed air is used for the operation of the decanter, which can be directly connected to the air main pipe of the aeration tank without the need for an additional air source.
