Abstract
The invention discloses a paper web stabilizer for a high-speed paper machine. A windpipe in parallel with the axis center of a baking cylinder is arranged between the baking cylinder and a vacuum roller; the windpipe is divided into a blowing area and a suction area; the suction area is uniformly provided with three rows of suction holes with the diameter of 10-80mm and the spacing of 40-60mm at the lower end and two sides of the windpipe; a paper guide area occupying 1/3 of the pipe length at one end of the windpipe is internally provided with an open/close valve; the blowing area is provided with a blowing pipe at the center of the windpipe; the inlet of the blowing pipe connected with a fan is arranged at one end of the windpipe; the circumference of the windpipe is welded and assembled with a partition plate by a steel plate; the wind in the blowing pipe flows by a space formed by the partition plate through the outlet at the middle part of the windpipe and blows out of a wind nozzle formed by the partition plate seam through the upper end and the lower end of the windpipe. When guiding the paper, the paper guide area can be separated from other areas, thus ensuring the paper to be closely attached to a dry blanket; the produced paper generates no rumple and is not easy to be broken; furthermore, the speed of the paper machine can be improved and paper guiding without rope can be realized.
Description
Technical field
The present invention relates to a kind of paper web stabilizer of high-speed paper machine.
Background technology
Existing high-speed paper machine mainly only is provided with single dryer and vacuum furnace, has following shortcoming: page is in the transmittance process of drying cylinder and vacuum furnace, and page can not be adjacent to dryer felt, and can float off dryer felt, makes to form air bag in the page, causes paper to produce gauffer; And disconnected easily paper; Whole paper machine speed is slow, the paper injection difficulty.
Summary of the invention
The objective of the invention is to overcome above shortcoming, a kind of paper web stabilizer of high-speed paper machine is provided.To realize that page can be close on the dryer felt, can not form air bag, the paper of production can not produce gauffer; Can improve the quality and the performance of page, not allow easily broken paper, make paper injection easier, and reach the raising paper machine speed, realize the purpose of wireless paper injection.
Technical scheme of the present invention is: be provided with the big airduct that is parallel to the drying cylinder axle center between drying cylinder and vacuum furnace, described big airduct is divided into blowing district and air draught district, described air draught district is evenly distributed with three rounds directly for 10-80mm, pitch-row are the wind inlet of 40-60mm in big airduct lower end and two sides, is provided with the switching valve in big airduct one end accounts for the paper injection district of pipe range 1/3rd; Described blowing district is provided with blower in the center of big airduct, the import of the blower that is connected with blower fan is located at an end of big airduct, assembled dividing plate in big airduct periphery with the steel plate welding, the wind of blower is blown out by the tuyere that the dividing plate slit constitutes by two ends about the big airduct after being flowed through in the space that dividing plate forms in the outlet at big airduct middle part.
Described open and close valve door is controlled automatically by the gentle bar of cylinder.
When page enters vacuum furnace and carries out paper injection, control valve is closed, paper injection district and other are separated out; Have only this moment big airduct one end to account in the paper injection district of pipe range 1/3rd three and just can carry out air draught, and other distinguishes not air draught; When paper injection finishes normal the use, control valve is opened, at this moment in the strong wind scope tube, all can be realized blowing or air draught; Can guarantee that like this page can be close on the dryer felt, can not form air bag, the paper of production can not produce gauffer; Can improve the quality and the performance of page; Do not allow easily broken paper yet, also can make paper injection easier, can improve paper machine speed; Realize wireless paper injection.

The specific embodiment
Embodiment:
With reference to accompanying drawing:
Between drying cylinder 1 and vacuum furnace 2, be provided with the big airduct 3 that is parallel to the drying cylinder axle center, described big airduct is divided into blowing district 4 and air draught district 5, described air draught district is evenly distributed with three rounds directly for 10-80mm, pitch-row are the wind inlet 6 of 40-60mm in big airduct 3 lower ends and two sides, is provided with autocontrol valve 7 in big airduct one end accounts for the paper injection district of pipe range 1/3rd three; Described autocontrol valve is to control by cylinder 8 gentle bars 9.
Described blowing district is provided with the blower 10 that is connected with blower fan in the center of big airduct, the import 15 of the blower that is connected with blower fan is located at an end of big airduct, assembled dividing plate 12 in big airduct periphery with the steel plate welding, the wind of blower is blown out by the tuyere 13 that the dividing plate slit constitutes by two ends about the big airduct after being flowed through in the space that dividing plate 12 forms in the outlet 11 at big airduct middle part.
When page enters vacuum furnace and carries out paper injection, control valve 7 is closed, paper injection district 14 is separated out with other; Have only this moment big airduct one end to account in the paper injection district 14 of pipe range 1/3rd three and just can carry out air draught, and other distinguishes not air draught; When paper injection finishes normal the use, control valve 7 is opened, at this moment in the strong wind scope tube, all can be realized blowing or air draught; Can guarantee that like this page can be close on the dryer felt, can not form air bag, the paper of production can not produce gauffer; Can improve the quality and the performance of page; Do not allow easily broken paper yet, also can make paper injection easier, can improve paper machine speed; Realize wireless paper injection.
