The shower pipe 57 is connected to two shower heads 59, whereby the temperature of the paper decreases as the web passes through the press section, so that the shower water at a higher temperature is used for shower steam, whereby the higher press temperature improves dewatering of the stock and reduces dryer vapors.
According to the invention, the tensioning device 12 and the correcting device 13 are matched with each other to adjust the felt 7, the tensioning device 12 mainly drives the sliding plate 18 through the driving device 17, the two tensioning rollers 20 move on the adjusting plate 16, the control distance between the two tensioning rollers 20 is adjusted, after adjustment, the fixing device 19 is fixed on the adjusting plate 16, if the felt 7 is too loose, the control distance between the two tensioning rollers 20 can be increased, the tensioning degree of the felt 7 is improved, if the felt 7 is too tight, the control distance between the two tensioning rollers 20 can be reduced, the tensioning degree of the felt 7 is weakened, the tension of the felt 7 can be controlled, and the felt 7 is prevented from loosening.
The signal detection device in the correction device 13 detects the transmitted felt 7, the signal sending end 22 sends out a signal, when the felt 7 normally runs, the felt 7 blocks a signal source, the signal receiving end 23 does not receive the signal, the lamp in the display is in a green normal state, when the felt 7 is deflected, the felt 7 does not block the signal source when slipping and loosening phenomena occur, the signal receiving end 23 receives the signal, the lamp in the display is in a red abnormal state, a worker lifts and adjusts the felt 7 through the lifting device 24, particularly the lifting device 24 comprises a lifting seat 36, a rotating rod 37 and a lifting roller 38, the rotating rod 37 is rotatably connected in the lifting seat 36, the lifting roller 38 is arranged below the felt 7, when the transmission path of the felt 7 is deflected, the lifting roller 38 is lifted by a certain height through the rotating action of the rotating rod 37, then the worker can rearrange the deflected felt 7 on the tensioning roller 20, and the tensioning device 12 adjusts the tension of the felt 7, so that the deflection of the felt 7 can be corrected.
The above is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto.
