Abstract
The utility model relates to the technical field of papermaking, in particular to a drying part of a high-speed paper machine. The drying part of the high-speed making machine structurally comprises drying cylinders arranged in an upper row, vacuum cylinders arranged in a lower row, guide rollers, transmission devices and a drying net, the drying net is sleeved on the drying cylinders and the vacuum cylinders and connected with the guide rollers and the transmission devices, the drying cylinders are used for connecting steam communicating pipes of a steam generator, and the vacuum cylinder is used for connecting air pipes of an air blower. By the aid of the drying part of the high-speed paper machine, running stability of a paper web is good, so that paper breakage is reduced; broken paper falls down directly in stead of being clamped in the drying cylinders or vacuum cylinder in case of paper breakage, cleaning is facilitated, cleaning time is short, and accordingly production efficiency is improved.
Description
Technical field
The utility model relates to pulp technology for making paper, particularly relates to the oven dry portion of high-speed paper machine.
Background technology
In the process of papermaking, paper web enters drying process after via squeezing process, moisture in the paper web reduces gradually, along with the aridity of paper web is more and more higher, the stable operation of paper web is more poor, and, because the speed of service of high-speed paper machine oven dry portion is very high, therefore, in the process of producing, the phenomenon of disconnected paper often appears easily.In addition, the waste paper that ruptures overstocks in oven dry portion, just need in time clear up.The oven dry portion of high-speed paper machine of the prior art, owing to adopt the multiple arrangement mode of hanging usually, namely one group of cylinder is provided with two dried nets, thereby when causing disconnected paper to take place, the paper that ruptures is stuck in drying cylinder or the vacuum reservoir easily, is difficult to cleaning, clearance time is long, has a strong impact on production efficiency.
Summary of the invention
The purpose of this utility model is to provide at weak point of the prior art the oven dry portion of high-speed paper machine, the oven dry portion of this high-speed paper machine can make the good operation stability of paper web, thereby reduce the generation of disconnected paper phenomenon, even disconnected paper situation takes place, the paper that ruptures can directly fall down, and can not be stuck in drying cylinder or the vacuum reservoir, makes to be easy to cleaning, clearance time is short, thereby has improved production efficiency.
For achieving the above object, the utility model is achieved through the following technical solutions.
The oven dry portion of high-speed paper machine is provided, comprise the row of being arranged at drying cylinder, be arranged at down row vacuum reservoir, deflector roll, transmission device and a dried net; Described dried net is located at described drying cylinder and described vacuum reservoir, and is connected with described transmission device with described deflector roll; Described drying cylinder is provided with for the vapor communication pipe that connects steam generator, and described vacuum reservoir is provided with for the airduct that connects blower fan.
The surface of described vacuum reservoir is provided with through hole.
The aperture of described through hole is set to 6.5mm ~ 7.5mm.
The aperture of described through hole is set to 7mm.
The quantity of described drying cylinder is set to seven.
The quantity of described vacuum reservoir is set to seven.
The beneficial effects of the utility model: the oven dry portion of high-speed paper machine of the present utility model, comprise the row of being arranged at drying cylinder, be arranged at down row vacuum reservoir, deflector roll, transmission device and a dried net; Dried net is located at drying cylinder and vacuum reservoir, and is connected with transmission device with deflector roll; Drying cylinder is provided with for the vapor communication pipe that connects steam generator, and vacuum reservoir is provided with for the airduct that connects blower fan.The oven dry portion of this high-speed paper machine can make the good operation stability of paper web, thereby reduces the generation of disconnected paper phenomenon, even and disconnected paper situation takes place, the paper that ruptures can directly fall down, and can not be stuck in drying cylinder or the vacuum reservoir, makes to be easy to cleaning, clearance time is short, thereby has improved production efficiency.
Description of drawings
Fig. 1 is the structural representation of the oven dry portion of high-speed paper machine of the present utility model.
In Fig. 1, include:
1---drying cylinder,
2---vacuum reservoir,
3---deflector roll,
4---transmission device,
5---dried net.
The specific embodiment
The utility model is described in further detail with the following Examples.
Embodiment 1.
See Fig. 1.The oven dry portion of the high-speed paper machine of present embodiment, comprise the row of being arranged at drying cylinder 1, be arranged at down row vacuum reservoir 2, deflector roll 3, transmission device 4 and a dried net 5; Dried net 5 is sheathed on drying cylinder 1 and vacuum reservoir 2, and is connected with transmission device 4 with deflector roll 3; Drying cylinder 1 is provided with for the vapor communication pipe that connects steam generator, and vacuum reservoir is provided with for the airduct that connects blower fan.In the process of producing, paper web also is adsorbed on the dried net 5.The oven dry portion of this high-speed paper machine can make the good operation stability of paper web, thereby reduce the generation of disconnected paper phenomenon, even disconnected paper situation takes place, the paper that ruptures can directly fall down, and can not be stuck in drying cylinder 1 or the vacuum reservoir 2, make to be easy to cleaning, clearance time is short, thereby has improved production efficiency.
In the present embodiment, the surface of vacuum reservoir 2 is provided with through hole.When vacuumizing in the vacuum reservoir 2, because the existence of through hole, dried net 5 firmly is adsorbed on the surface of vacuum reservoir 2, thereby make that also the paper web that is arranged on the dried net 5 firmly is adsorbed on the dried net 5, reduced the bubble between paper web and the dried net 5, make the good operation stability of paper web, thereby reduce the generation of disconnected paper phenomenon.
In the present embodiment, the aperture of through hole is set to 7mm.The through hole in this aperture makes vacuum reservoir 2 be difficult for stopping up, and has guaranteed vacuum reservoir 2 ordinary production, and can make dried net 5 be adsorbed in the surface of vacuum reservoir 2 preferably.
In the present embodiment, the quantity of drying cylinder 1 is set to seven, and the quantity of vacuum reservoir 2 is set to seven.Certainly, according to demand of practical production, the quantity of the quantity of drying cylinder 1 and vacuum reservoir 2 all can arrange arbitrarily.
Embodiment 2.
The embodiment 2 of the oven dry portion of high-speed paper machine of the present utility model, the difference of present embodiment and embodiment 1 is that the aperture of through hole is set to 6.5mm, and the through hole in this aperture makes vacuum reservoir 2 be difficult for stopping up, guaranteed vacuum reservoir 2 ordinary production, and enough made dried net 5 be adsorbed in the surface of vacuum reservoir 2.Other structure and the operation principle of present embodiment are identical with embodiment 1, do not repeat them here.
Embodiment 3.
The embodiment 3 of the oven dry portion of high-speed paper machine of the present utility model, the difference of present embodiment and embodiment 1 is, the aperture of through hole is set to 7.5mm, the through hole in this aperture makes vacuum reservoir 2 be difficult for stopping up, guaranteed vacuum reservoir 2 ordinary production, and can make dried net 5 be adsorbed in the surface of vacuum reservoir 2 securely.Other structure and the operation principle of present embodiment are identical with embodiment 1, do not repeat them here.
