<p>PURPOSE:To facilitate the maintenance and inspection of a submerged mixer by easily raising and lowering the mixer by positioning an air outflow part in front of the submerged mixer when the submerged mixer rising and falling along a guide pipe falls to be positioned. CONSTITUTION:A chain 18 is engaged with a chain hoist to suspend a submerged mixer 11 along a guide pipe 2 and, when the submerged mixer 11 comes into contact with a stopper 17, an air diffusing pipe 6 is positioned in front of the submerged mixer 11. When a current is supplied to the submerged mixer 11 to rotate a blade 14, the water around a stand 12 is sucked in a draft ring 15 by the blade 14 to become a strong jet revolving stream under stirring and pushed out forwardly. The air sent through an air supply pipe 7, the guide pipe 2 and an air pipe 5 is injected from the air diffusing pipe 6 in front of the submerged mixer 11 to be stirred by the revolving stream of the submerged mixer and mixed with water as minute air bubbles to advance.</p> |
