PURPOSE: An aeration type submersible mixer is provided to enhance the efficiency of mixing with precipitates under the water. CONSTITUTION: An aeration type submersible mixer (100) is manufactured by fastening an impeller (20) to one side of a rotary shaft (13) from a casing (11) of a submersible motor (10) with a mechanical seal. An air inlet connected to an air supply pipe (H) from outside is formed in the rear side of the case in which the rotary shaft is penetrated. An air supply case (14) having an inner space connected to the air inlet is installed tightly. The rotary shaft comprises a hollow shaft for passing the air through the air supply case. One end of the rotary shaft has a fastening part (13a). A nut (N) is connected in penetration into a central combining hole (21) of the impeller. |
