As shown in fig. 1, an air agitation tank of the present invention comprises: the device comprises a tank body 2, a central cylinder 3, a first compressed air pipe 8, a second compressed air pipe 5, a hanging rod 6 and a supporting plate 7. The upper part of the tank body 2 is a straight cylinder section, and the lower part of the tank body 2 is a cone section, which is beneficial to the liquid medium with high solid content to settle to the bottom of the cone section of the tank body 2. The center cylinder 3 is arranged in the center of the tank body 2, the upper end of the center cylinder 3 is positioned on the straight cylinder section, and the lower end of the center cylinder extends to the lower part of the cone section of the tank body. The supporting plate 7 is fixed on the top cover of the tank body 2, one end of the hanging rod 6 is fixed with the upper end of the central cylinder 3, the top cover with the other end extending out of the tank body 2 is fixed on the supporting plate 7, and during specific implementation, a plurality of hanging rods 6 can be arranged to bear the gravity of the central cylinder 3. The upper end of first compressed air pipe 8 and second compressed air pipe 5 all stretches out and fixes in the backup pad from the top cap of cell body 2, compressed air is let in to the upper end of first compressed air pipe 8, and the lower extreme extends the cone section lower part of cell body 2, compressed air is let in to the upper end of second compressed air pipe 5, and the bottom of second compressed air pipe 5 stretches into in central section of thick bamboo 3 from the lateral wall of central section of thick bamboo 3.

The tank body 2 is internally provided with an overflow plate 4, the overflow plate 4 is of an annular structure and is sleeved on the edge of the upper end cylinder opening of the central cylinder 3, and the arrangement of the overflow plate 4 is favorable for increasing the stirring area of the liquid medium in the tank body 2. The air stirring tank also comprises an annular skirt seat 9, wherein the skirt seat 9 is arranged outside the tank body 2 and fixed at the joint of the straight cylinder section and the cone section so as to support the tank body 2 on the air stirring tank base, and meanwhile, the skirt seat 9 is arranged to strengthen the rigidity of the cylinder wall of the tank body 2. The side wall of the lower end of the central cylinder 3 is provided with a plurality of support rods 10, the tail ends of the support rods 10 are supported on the inner wall of the cone section, and the support rods 10 can ensure the stability of the central cylinder 3 during operation.

The air stirring tank also comprises a feed inlet 1 and a discharge outlet 11, wherein the feed inlet 1 is arranged on a top cover of the tank body 2 or on the side wall of the straight cylinder section; the discharge hole 11 is arranged at the bottommost part of the cone section.

Liquid media with high solid content enter the tank body 2 from the feed inlet 1, liquid is separated in the tank body 2, a clear liquid layer is suspended on the liquid level at the top in the tank, and impurities such as the media with high solid content, mud stones and the like are settled on the cone section of the tank body 2 under the action of gravity and finally gathered at the bottom of the cone section. Since the first compressed air pipe 8 and the second compressed air pipe 5 are continuously charged with compressed air. At this moment, the high solid content medium and impurities such as mud stone at the bottom of the cone section enter from the bottom of the central cylinder 3 under the action of compressed air, are discharged from the top of the central cylinder 3, are finally mixed with the upper clear liquid layer in the tank body 2, the mixed liquid medium runs from top to bottom in the tank body 2, and finally the discharge outlet valve is opened and is discharged from the discharge outlet 11. The discharged liquid medium meets the requirements of the process production, promotes the uniform mixing of liquid and solid, and has no sediment and scab at the cone bottom.
