Abstract
The utility model discloses a novel double-screen press master press roll of a P-RC-APMP pulping system, and solves the problems of other technologies. The press roll adopts the structure that an upper filter screen is respectively sleeved on a rectifying roll, a tension roll, an upper side first press roll, a second press roll and a third press roll and connected with a filter board; a longitudinal tension roll is fixed on a pulp distribution box; the filter board is fixed on a pulp distribution box; a lower filter screen is respectively sleeved on a lower rectifying roll, a lower tension roll, a lower side first press roll, a second press roll and a third press roll and connected with the filter board; each press roll is provided with an independent reducing motor; the upper side first press roll, the second press roll and the third press roll are respectively fixed on a bracket; the lower side first press roll, the second press roll and the third press roll are respectively swung through the stretching of a pneumatic tire; linear pressure along the part between the press rolls can be adjusted by adjusting the air pressure of the pneumatic tire; and the upper and the lower filter screens are driven to operate.
Description
One, technical field: the utility model relates to a kind of paper-making pulping device, especially the novel twin-wire press pressure roller of P-RC-APMP pulping system
Two, background technology: present most of pulp and paper production uses two net shoves to be the twin pressure roller device, slurry is by carrying out gravity dehydration on the off line arc dehydration filter plate, the wedge shape drying zone that closes up gradually by two nets carries out double dewatering then, enter s type pressing device then, enter the further reinforcement dehydration that high line pressure presses again, obtain the slurry of 28-32% concentration.
Three, summary of the invention: the purpose of this utility model provides a kind of easy and simple to handle, the novel twin-wire press pressure roller of safe and reliable P-RC-APMP pulping system, it has solved the problem that other technology exists, the purpose of this utility model is to realize like this, it is by two correction rollers up and down, screen pack up and down, tightening roller up and down, cloth slurry case, filter plate, one pressure roller of twice up and down, second press roller and three road pressure roller are formed by connecting, last screen pack is enclosed within the correction roller respectively, tightening roller, one pressure roller in top, on second press roller and the three road pressure roller, and be connected with filter plate; Tightening roller is fixed on the cloth slurry case up and down, and filter plate is fixed on the cloth slurry case; Following screen pack is enclosed within down respectively on correction roller, following tightening roller, following one pressure roller, second press roller and the three road pressure roller, and is connected with filter plate; Every pressure roller are provided with independently reducing motor, one pressure roller of top, second press roller and three road pressure roller are separately fixed on the support, following one pressure roller, second press roller and three road pressure roller are swung by the flexible of pneumatic tyre respectively, can adjust by regulating pneumatic tyre air pressure along the linear pressure between the pressure roller, and drive upper and lower filter screen operation.
Operation principle: every pressure roller are provided with independently reducing motor, upper press is fixed on the support, lower press is swung by the flexible of pneumatic tyre, linear pressure between the roller can be by regulating the adjustment of pneumatic tyre air pressure, and drive the operation of upper and lower filter screen, reducing motor is by variable frequency control, and the synchronous operation that should keep two rollers.By regulate spacing on the doctor blade device handle make scraper near upper and lower filter in case the slurry layer of felted peel off from filter screen.
Meaning of the present utility model: be widely used in the high density bleaching of hot decentralized system, the mechanical pulp of waste paper, thick slag system such as regrind; The forming part of market pulp board machine; Mechanical pulp, careless plasmoid for low freedom are also very suitable.The one, easy and simple to handle, simple in structure.The 2nd, use two net wedge shape dewatering Principle, the combination dehydration of dehydration filter plate and three press-roller devices; Nip is long, pressure differential strengthens gradually, cocnentration factor height, pulp concentration can be stabilized in about 35%, has saved cost of transportation.The 3rd, folder net wedge shape moulding dehydration filter plate and three drying zones combinations of three press-roller devices, novel structure, few, the concentrated energy consumption of fiber loss are low.The 4th, the operation of PCL control system is more stable.
Four, description of drawings: Fig. 1 is the structural representation of the novel twin-wire press pressure roller of P-RC-APMP pulping system, among the figure 1, correction roller 2, screen pack 3, tightening roller 4, cloth slurry case 5, filter plate 6, one pressure roller 7, second press roller 8, three road pressure roller
Five, the specific embodiment: in Fig. 1, last screen pack 2 is enclosed within respectively on correction roller 1, tightening roller 3, one pressure roller in top 6, second press roller 7 and the three road pressure roller 8, and is connected with filter plate 5; Following screen pack 2 is enclosed within down respectively on correction roller 1, following tightening roller 3, following one pressure roller 6, second press roller 7 and the three road pressure roller 8, and is connected with filter plate 5; Tightening roller 3 is fixed on the cloth slurry case 4 up and down, and filter plate 5 is fixed on the cloth slurry case 4; Every pressure roller are provided with independently reducing motor, one pressure roller 6 of top, second press roller 7 and three road pressure roller 8 are separately fixed on the support, following one pressure roller 6, second press roller 7 and three road pressure roller 8 are swung by the flexible of pneumatic tyre respectively, can adjust by regulating pneumatic tyre air pressure along the linear pressure between the pressure roller, and drive upper and lower filter screen operation.
