[0030] When the driving shaft 3 rotates, the two spiral blades 4 and the rotating blade 5 are driven to rotate, forming a stirring and mixing effect on the coal slime and the flotation agent in the flotation box 1. The two spiral blades 4 rotate to push part of the coal slime at the top and the bottom of the flotation box 1 to flow to the middle part. The rotating blade 5 rotates to push the coal slime in the middle part to flow to the middle side wall of the flotation box 1, facilitating subsequent extrusion and crushing treatment of the coal slime.

[0031] The extrusion mechanism includes a plurality of electric telescopic rods 6, which are divided into two groups and are installed one by one on the top and the bottom of the flotation box 1.
