The utility model is adapted to the dewatering process in papermaking.
Description
Technical field
The utility model relates to paper making equipment, copies the paper dewater unit in the particularly papermaking program.
Background technology
When prior art was made toilet paper and copied paper, suction flat box became level to install with woollen blanket, because moisture is from away from one side to close vacuum, one side of vacuum, moisture passes through on woollen blanket always, easily cause aspiration end moisture excessive, dehydration is uneven, the paper basis weight instability; Besides, drying cylinder adopts single blind press on the page, causes the page costs and poor dehydration results, and drying cylinder steam consumes big, and the operating cost of ton paper is very high.
Summary of the invention
The utility model will solve and copy paper dehydration inequality at present, the paper basis weight instability, and the problem that energy consumption is big provides a kind of papermaking dehydration treatment equipment of the present utility model for this reason, and this device is copied the paper dehydration evenly, and paper basis weight is stable, and energy consumption is low.
For addressing the above problem, the technical solution adopted in the utility model comprises suction flat box, pressing device and drying cylinder, band slurry woollen blanket entrance front end place is provided with deflector roll, described band slurry woollen blanket entrance is provided with suction flat box I and suction flat box II, its special character is described band slurry woollen blanket entrance and suction flat box I, the working face of suction flat box II and horizontal direction have an angle α, described deflector roll the place ahead is provided with by a swing arm, a pressing device of a pneumatic tyre and a pressure roller composition, be provided with and clean roller later in pressure roller output the place ahead of turning back, this cleaning later is provided with by No. two swing arms in the roller output the place ahead of turning back, No. two pressing devices of No. two pneumatic tyres and No. two pressure roller compositions, the woollen blanket outlet section is positioned at No. two pressure roller outbound course of turning back, described drying cylinder is positioned at and pressure roller and No. two tangent positions of pressure roller, the angle β of pressure roller center and the drying cylinder line of centres and vertical curve is 15～20 °, a pressure roller center, the angle γ of No. two squeezing centers and the drying cylinder line of centres is 30～35 °.
Described angle α is preferably 5～10 °, is preferably 6.5 °.
Described angle β is preferably 18 °, and described angle γ is preferably 32 °.
Have 120 ° of vacuum chambers in the described pressure roller.
The utility model will the paper pulp band after pre-treatment invests copies the paper woollen blanket, band slurry woollen blanket entrance dewaters through the twice suction flat box, suction flat box and horizontal direction have the angle of having a down dip, make suction flat box moisture when suction arrive another side along one side of vacuum tank pipe, can not flow through from woollen blanket, the dehydration that makes page is homogeneous more, and is quantitatively more stable.After page dewaters through suction flat box, enter a pressing device dehydration, dehydration back page changes drying cylinder over to, woollen blanket is by cleaning after later roller cleans, and by No. two pressing devices press dewatering once more, the page that changes drying cylinder over to squeezed once more after the ephemeral fever baking, moisture in the page is taken away by woollen blanket, web dryness further improves, and has alleviated the drying load of drying cylinder, has reduced the steam consumption.Pressure roller have the utility model of vacuum chamber, carry out vacuum dehydration, better effects if in squeezing.
Description of drawings
Fig. 1 is the utility model structural representation;
