The impeller 3 is arranged in the processing tank 101; the impeller 3 is connected to the driving end of a first driving mechanism 301 arranged on the tank body 1; the first driving mechanism 301 is a motor, and a waterproof protective cover is sleeved outside it. The air pump 4 is arranged at the side wall of the tank body 1; a pipeline communicating with the processing tank 101 is arranged on the air pump 4, and a one-way valve is arranged on the pipeline, and air can be introduced into the processing tank 101 to accelerate the generation of foam. The flow-pushing component 5 is arranged above the processing tank 101, and the foam is pushed to flow by the rotation of a plurality of pushing plates 513. The material-blocking component 6 is arranged below the flow-pushing component 5, and the upper end of the processing tank 101 is closed by the unfolding of a plurality of filter plates 62, so as to prevent the pulp fibers from flowing out.

[0021] Further explanation, the flow-pushing component 5 includes a flow-pushing member 51 that pushes the foam to flow by the rotation of a plurality of pushing plates 513; and a moving member 52 that drives the flow-pushing member 51 to reciprocate to further expand the pushing range of the flow-pushing member 51.

[0022] Further explanation, the moving member 52 is symmetrically provided with two groups about the flow-pushing member 51; the moving member 52 includes a fixed plate 521 symmetrically arranged at the side wall of the tank body 1; a threaded rod 1 522 is rotatably connected between the fixed plates 521 on both sides; one end of the threaded rod 1 522 is connected to the driving end of the driving mechanism 3 523 arranged on the fixed plate 521, and a slider 524 is also threadedly connected thereon; a slide bar is arranged on the side opposite to the threaded rod 1 522 in the tank body 1, and a slider 524 is also slidably connected to the slide bar; the driving mechanism 3 523 is a motor. The flow-pushing member 51 includes a rotating shaft 512 rotatably connected between two sliders 524; one end of the rotating shaft 512 is connected to the driving end of the driving mechanism 2 511 arranged on the slider 524, and a plurality of push plates 513 are arranged at the side wall; the driving mechanism 2 511 is a motor. The foam can be pushed toward the direction of the waste tank 102 by rotating the plurality of push plates 513, thereby accelerating the flow velocity of the foam, and thus improving the flotation efficiency. At the same time, it can also prevent the foam from accumulating in large quantities and causing the liquid level to rise, thereby preventing the pulp from following the foam and flowing into the waste tank 102. The arrangement of the moving member 52 can expand the pushing range of the flow pushing member 51, so that the foam above the processing tank 101 can be pushed.

[0023] Further explanation, the material blocking assembly 6 includes a plurality of filter plates 62; the plurality of filter plates 62 are slidably connected to each other, and the plurality of filter plates 62 are all slidably connected to the inner wall of the tank body 1; a threaded rod 2 63 is also provided above the plurality of filter plates 62; one end of the threaded rod 63 is rotatably connected to the tank body 1, and the other end is rotatably connected to the baffle 2; the threaded rod 2 63 is also connected to the driving end of the driving mechanism 4 64 provided on the tank body 1, and a connecting plate 65 is threadedly connected thereto; the driving mechanism 4 64 is a motor; the connecting plate 65 is connected to the filter plate 62 near the baffle 2.
