Pneumatic mixing device for preventing coal water slurry from settling

The utility model relates to a pneumatic mixing device for preventing coal water slurry from settling. The pneumatic mixing device comprises a mixing pipe body, and a mixing pipe comprises an upper fixed end, a rotating shaft fulcrum and a lower shaft body, wherein the upper fixed end is provided with compressed air inlets, and the side surface and the bottom of the lower shaft body are provided with compressed air outlets. According to a working principle of the mixing device for preventing coal water slurry from settling, the mixing device is provided with the upper fixed end, the upper fixed end is provided with the compressed air inlets, and the mixing device can be directly used in a coal water slurry storage tank or a coal water slurry transport cart; the side surface and the bottom of the lower shaft body are provided with the compressed air outlets, so that pneumatic mixing is realized; meanwhile, with the rotating shaft fulcrum on the mixing pipe, the lower shaft body is capable of swinging rotatably, so that coal water slurry in corners in the coal water slurry storage tank or the coal water slurry transport cart is uniformly mixed.
