| 摘要 | Apparatus for the fluid treatment of thread or sheet-like material with fluids comprising, a perforated drum about which the material to be treated is wrapped, and characterized in that a member is arranged within the drum to reduce the space therein to be occupied by the fluid so that efficient treatment may be effected with a relatively small amount of fluid. | ||||||
| 权利要求 | 1. Apparatus of the class described comprising a drum having a perforated jacket for the treatment of thread or sheet-like material with fluid, and through the interior of which the treatment medium circulates, characterized in that a hollow displacement body (7, 19) is arranged in the interior of the drum and cooperates with same to reduce the spatial volume therebetween. 2. Apparatus according to claim 1, characterized in that the displacement member (7, 19) is in coaxial relationship with the drum and is supported relatively to the jacket by means of spacers (11). 3. Apparatus according to claim 2, characterized in that rigidifying discs (8, 9, 10) are provided in the interior of the body in the planes of the spacers (11). 4. Apparatus according to claim 1, characterized in that the displacement member (19) is of streamline shape and in that the flow space is gradually reduced from the fluid introduction end of the drum to the opposite end thereof. 5. Apparatus according to claim 1, characterized in that a bent tube (18), mounted to swivel between several positions is provided in the drum to evacuate air or treatment fluid therefrom. 6. Apparatus according to claim 1, characterized in that two tubes are provided in the drum, one of which serves to evacuate air and tHe other of which serves to evacuate treatment fluid therefrom. 7. Material drum according to claim 1, characterized in that the displacement member is arranged to be buoyant in a fluid in the interior of the drum. 8. Apparatus of the class described comprising a drum having a perforated jacket for treatment of thread of sheet-like material with fluid, and through the interior of which the treatment medium circulates, a hollow displacement body (7, 19) being mounted in the interior of the drum in co-axial relationship, said body being supported relatively to the jacket by means of spacers (11) and rigidifying discs (8, 9, 10) being provided in the interior of said body in the planes of the spacers (11). |
