Each dividing plate 2 has the wastepaper as raw material liquid a among each chamber 3a～3c and forms thereon froth bed d and the height that separates of the 3a～3c of adjacent room.
And, direction of principal axis along the rotation diffuser 4 of the upper end of treatment trough 1, be provided with the foam launder 9 that is used for discharging the foam c that overflows from froth bed d in the left and right sides, surmount the foam c that the dividing plate 50 of foam launder 9 overflows and discharge from foam outlet 51 by foam launder 9 to the outside.
Each dividing plate 2 exists to the position higher than the dividing plate 50 of foam launder 9.
At each dividing plate 2,2, be formed with and be used for wastepaper as raw material liquid a is sent to the raw material drive access of the 3b of adjacent room, the 3c in downstream successively from the chamber 3a of upstream, the chamber 3a～3c with adjacency is communicated with each other by this raw material drive access.The raw material drive access is formed by the through hole 10 that is located at dividing plate 2 bottoms and the gap 11 of inserting between the rotation diffuser 4 of this through hole 10.

Be positioned at adjacent chamber 3a, 3b, chamber 3b, the 3c in the downstream of 3b, 3c is provided with and fast prevents plate 40, this prevents that fast plate is used to make the wastepaper as raw material liquid a that flows into from chamber 3a, the 3b of upstream side by raw material drive access 11 in the chamber in this downstream 3b, 3c after the circulation, make it again to flow out, prevent not circulation and directly being discharged fully in chamber 3b, 3c of wastepaper as raw material liquid from raw material drive access 11 or raw material outlet 8.
At the peripheral edge portion of the inner bottom surface of treatment trough 1, in order to prevent the stagnation of wastepaper as raw material liquid a, and form flexure plane 1a with circularity, corresponding therewith, end also forms curved shape at each above-mentioned dividing plate 2 and about fast preventing the bottom of plate 40.
The rotary speed (peripheral speed) of above-mentioned rotation diffuser 4 for the compressed air from air diffuser 4c ejection forms fine bubble among wastepaper as raw material liquid a, is preferably 5～20m/s, more preferably 14～19m/s.
If consider by the obstruction that causes adhering to of wastepaper as raw material liquid a etc., then the shape of air diffuser 4c is preferably along the long hole shape of the axis direction of rotation diffuser 4.And the aperture opening ratio with respect to the outer peripheral face area of the 4a of cylinder portion that is formed by each air diffuser 4c is preferably 5～15%.
For carrying out deinking consistently, handles the liquid level that makes the wastepaper as raw material liquid a that supplies in each chamber 3a～3c, with respect to the flow L (m of the wastepaper as raw material liquid a in each chamber 3a～3c
3/ time), be used to form the bubble b that in this wastepaper as raw material liquid a, sprays and the air quantity delivered G (Nm that supplies with to rotation diffuser 4
3/ time) ratio, i.e. air supply rate G/L is preferably 2≤G/L≤15.
Air quantity delivered G for example, is 15～35m in the total capacity of the treatment trough 1 that is divided into Room 3 (than the capacity of froth bed d by the liquid layer of below)
3Situation under, be preferably 250～900Nm
3/ time.
Preferably, the flow velocity of the wastepaper as raw material liquid in the raw material drive access 11 is 0.05～0.2m/s.
Because if G/L is less than 2, the bubble b that then is used for adhering to the ink particle that wastepaper as raw material liquid a swims is very few, and therefore, deinking is insufficient.In addition, greater than 15, then bubble b too much hinders the formation of froth bed d, so undesirable as if G/L.
