る。[Prior Art] Since the sludge sent to the stirring tank under mixed pressure has a large fluidity, it is necessary to mix a solidifying agent to solidify the sludge. Conventionally, when the solidifying agent is mixed in the sludge, as shown in FIG. 3, the stirring blade 5 concentrically provided in the stirring tank 1 is rotated by the electric motor 13 and the chain 14 in the sludge 3 to rotate the rotary shaft. The solidifying agent 6 is inserted into the hollow portions of the stirring blade 5 and the stirring blade 5, and the solidifying agent 6 is extracted into the sludge 3 from the injection holes 8 scattered in the stirring blade 5.
［考案が解決しようとする課題］ 従来の装置にあっては、攪拌翼を回転させるために、電
動機のエネルギが必要である。しかるに混気圧送で攪拌
槽に投入されるヘドロの運動エネルギは無駄に捨てられ
ている。[Problems to be Solved by the Invention] In the conventional device, the energy of the electric motor is required to rotate the stirring blade. However, the kinetic energy of the sludge that is fed into the stirring tank by the mixed pressure feeding is wasted.
本考案は、上記のヘドロの運動エネルギを利用して攪拌
翼を回転させることを技術的課題としている。The present invention has a technical problem to rotate the stirring blade by utilizing the kinetic energy of the sludge.

た。[Means for Solving the Problems] In a vertical cylindrical sludge agitation tank in which a solidifying agent is injected from an agitation rotary shaft, a sludge discharge pipe connected horizontally and tangentially to the upper part of the agitation tank body is provided for agitation. An impeller having a plurality of blades was fixed to the stirring rotary shaft at a position facing the sludge discharge pipe above the stirring rotary shaft installed on the central axis of the tank.
［作用］ 上記のように構成された装置では、混気圧送で攪拌槽に
投入されるヘドロの運動エネルギは、そのヘドロが羽根
車の受面に衝突することにより攪拌装置の攪拌軸ならび
に攪拌翼を回転させる。[Operation] In the apparatus configured as described above, the kinetic energy of sludge thrown into the stirring tank by mixed pressure feeding is such that when the sludge collides with the receiving surface of the impeller, the stirring shaft of the stirring apparatus and the stirring blades. To rotate.

Sludge 3 is stirring vessel 1 which has been fed mixed air pressure in When discharged to, the impeller collides with the receiving surface of the impeller 4 and rotates the stirring blade 5 and the stirring shaft 7. on the other hand,
The solidifying agent 6 is poured into the sludge 3 through a solidifying agent introducing pipe 10, a rotary joint 11 and a hollow stirring shaft 7 through an injection hole 8 provided in the stirring blade 5. The sludge 3 and the solidifying agent 6 are mixed by a stirring blade 5, and are cut out while being further stirred and mixed by a screw feeder 9 driven by a motor 12 provided below.
［考案の効果］ 本考案は、以上説明したように、攪拌翼は混気圧送され
