Abstract

A decanter without power source is composed of a water receiving unit on water surface, a drainage unit and a transmission unit. Said water receiving unit has a float movable along a vertical track with upper and lower limiters and connected to drainage tube which is connected to drainage trunk at bottom of container. A water level sensor is connected to the electromagnetic valves respectively for water pouring tube and drainage trunk. Its advantages are no need of external power unit and sealing, low cost and high running stability.

Description

Technical field [0001] The invention relates to a drainage device, in particular to a decanter. Background technique [0002] In the drainage operation of the variable water level container, the requirements for the decanter are: timely drainage without disturbing the sludge layer. The existing decanter can be divided into mechanical type, automatic type and a combination of mechanical and automatic from the transmission mode, and can be divided into siphon type, hose type, float type and sleeve type from the weir mouth. In terms of form, it can be divided into pontoon type and disc type. At present, the main types of decanters used in the intermittent activated sludge wastewater treatment system (SBR) are as follows: electric mechanical rocker decanters, sleeve decanters, siphon decanters, Rotary type decanter, float type decanter. [0003] The existing decanter generally consists of a water collection device, a drainage device and a power transmission device. The water collecti...
