Abstract:
The present invention relates to a stirring device for water treatment. The stirring device for water treatment includes: a driving part including an impeller rotated by a driving motor and a first floating part for preventing the motor from being immersed; an inflow part, which is a tube body vertically immersed within a water area, through which foreign substances deposited on a bottom of the water area are suctioned by the rotation of the impeller; a discharge part disposed between the driving part and the inflow part to discharge the foreign substances suctioned from the inflow part toward an upper portion of the water area, the discharge part including at least one second floating part so that the stirring device is adjusted in height to correspond to the discharging region and a change of a water level. In the stirring device, floating parts having adjustable buoyancy may be provided so that the stirring device is stably installed in a water treatment plant as well as open spaces such as a stream, a reservoir, a river, the sea, and the like. Also, the stirring device may be balanced and adjusted in buoyancy by means of the floating parts to correspond to the change of the water level. Also, the foreign substances in various depths may be selectively discharged through the floating parts to more efficiently perform the stirring process. Thus, water within a polluted water area may be easily purified. Also, since the stirring device can be installed in open spaces, water within various polluted areas may be purified. In addition, since the driving part of the stirring device is exposed through the floating parts, it may prevent the driving part from being immersed, and also safe working above a water surface may be possible to improve maintenance efficiency of the device.
