Abstract
The utility model relates to the technical field pulping and paper making, in particular to a vacuum drawing type dehydration device of a squeezing portion of a paper machine, which is composed of a motor, a vacuum pump and vacuum water sucking boxes and is characterized in that 1 to 2 vacuum water sucking boxes are fixed on a lower blanket surface of a lower coarse calico and communicated with a vacuum pump driven by a motor. When the paper machine operates, the lower coarse calico is separated from a paper web and then passes through a coarse calico water squeezing roller in returning, water contained in the lower coarse calico is squeezed out by the coarse calico water squeezing roller, when the lower coarse calico passes through the 1 to 2 vacuum water sucking boxes arranged behind the coarse calico water squeezing roller, wet-back water contained in the lower coarse calico is removed, then the lower coarse calico is transmitted by a return roller of the lower coarse calico so as to achieve squeezing and dehydration of the paper web. The vacuum drawing type hydration device promotes uniformity in dehydration of the squeezing portion, obviously reduces the phenomena of folding, bubbling and the like of the paper web of the squeezing portion, reduces paper blocking time and improves operation efficiency of the paper machine.
Description
Affiliated technical field
The utility model relates to the pulp and paper technology field, specifically a kind of vacuum pumping-type dewater unit of paper machine press section.
Background technology
At present, in the pulping and paper-making field under the press section of a paper machine felt turn one's head to be designed to the felt squeeze roll before the roller, following felt and paper web break away from the back and dewater through the felt squeeze roll in backhaul, realize the paper web press dewatering by roller transmission later then.But in service in actual production, following felt is wet through taking place back behind the felt squeeze roll, contains excessive moisture in the following felt, causes phenomenons such as foldover, bubbling occurring after the press for extracting juice of paper web entrance pressure, causes disconnected paper, reduces paper machine operation efficient.
Summary of the invention
The purpose of the utility model is in order to overcome above deficiency; A kind of vacuum pumping-type dewater unit of paper machine press section is provided; Use this vacuum pumping-type dewater unit can remove down the excess water that felt contains after through the felt squeeze roll, promote press section dehydration uniformity, obviously alleviate phenomenons such as press section paper web foldover, bubbling; Reduce disconnected paper number of times, improve paper machine operation efficient.
The utility model solves the technical scheme that its technical problem adopted: a kind of vacuum pumping-type dewater unit of paper machine press section; Form by motor, vavuum pump and suction flat box; It is characterized in that: fixing 1～2 suction flat box of blanket face under the following felt, suction flat box is communicated with the vavuum pump of driven by motor.
The beneficial effect of the utility model is that promotion press section dehydration uniformity obviously alleviates phenomenons such as press section paper web foldover, bubbling, reduces disconnected paper number of times, improves paper machine operation efficient.

1. motors among the figure, 2. vavuum pump, 3. suction flat box.
The specific embodiment
This vacuum pumping-type dewater unit is made up of motor 1, vavuum pump 2 and suction flat box 3, it is characterized in that: fixing 1～2 suction flat box 3 of blanket face under the following felt, suction flat box 3 is communicated with the vavuum pump 2 that motor 1 drives.
When paper machine operation; Following felt and paper web break away from the back at backhaul process felt squeeze roll; The felt squeeze roll removes down the moisture that contains in the felt; During 1～2 suction flat box 3 that following felt is provided with after through the felt squeeze roll, the wet moisture that returns that wherein contains is removed, and descend felt by the press dewatering of the realization of roller transmission later to paper web then.This vacuum pumping-type dewater unit has promoted press section dehydration uniformity, has obviously alleviated phenomenons such as press section paper web foldover, bubbling, reduces and resolves the paper number of times, has improved paper machine operation efficient.
