Abstract
One kind makes the equally distributed method and device of pulp-water in paper machine forming part head box, and methods described is to be blown into wind to closed headbox casing top, and uniform blast is applied being covered with above the slurry of casing, is uniformly distributed pulp-water in paper machine forming part head box.Described device includes sending slurry pipe (3), being arranged to send and enter stock pump (4) on slurry pipe for slurry tank (1), closed headbox (2), connection slurry tank (1) and closed headbox (2), the blast pipe (5) dried to head box casing top and the low pulse Roots blower (6) being installed on blast pipe.The present invention can be uniformly distributed pulp-water in paper machine forming part head box, to obtain paper substrate in uniform thickness.
Description
Technical field
The invention belongs to paper machine forming part head box technical field.
Background technology
Paper machine forming part is generally made up of head box, breast roll, forming net, suction box, couch roll etc., and system will be streamed by entering stock pump
The paper pulp sent of uniting is pumped to head box, and casing is covered with after pulp distributor, then is sprayed from grout outlet to forming net, after dehydration
Paper substrate is obtained, wherein, the online uniformity of paper pulp influences larger to the quality of paper, and paper pulp online is uneven to be caused to prepare
Paper substrate is in uneven thickness, has a strong impact on the thickness evenness of finished paper and the performance of paper.Existing head box pulp distributor
Enter to starch house steward use side taper return duct, pulp-water is evenly distributed to forming net below by pumping the interior pressure produced
On, control branch pipe to starch the stabilization of flowing pressure and being evenly distributed for slurry by the refluxing opening set by step diffuser headbox one end.
But taper backflow overpressure in the side's of being due to can change with the pressure change for entering stock pump, and build-up of pressure is unstable, influences starching
The uniformity.
The content of the invention
The invention aims to solve the deficiencies in the prior art there is provided one kind to make in paper machine forming part head box
Pulp-water is uniformly distributed, to obtain the method and device of paper substrate in uniform thickness.
The purpose of the present invention is achieved through the following technical solutions：
Make the equally distributed method of pulp-water in paper machine forming part head box, this method is to closed headbox casing top
Portion is blown into wind, and uniform blast is applied being covered with above the slurry of casing, pulp-water in paper machine forming part head box is uniformly divided
Cloth.
Make the equally distributed device of pulp-water in paper machine forming part head box, including slurry tank, closed headbox, company
Connect slurry tank and sending for closed headbox starches pipe, is arranged to send and enters stock pump on slurry pipe, dried to head box casing top
Blast pipe and the low pulse Roots blower being installed on blast pipe.
Using the inventive method and device, stable wind is blown into head box casing top, the slurry of casing can be covered with
Layer top forms stable blast, even if the pressure in square taper return duct entered slurry pump pressure change and cause it is unstable, but
Classical prescription taper return duct enters the slurry in casing under the Action of Wind pressure of top homogeneous constant, still can uniformly spread out,
Keep uniform thickness, it is ensured that enter the slurry stable and uniform of rear portion forming net, production obtains paper substrate in uniform thickness.The present invention
Method is skillfully constructed, and device is simple and reliable, can directly be transformed on prior art device, manufacturing cost is low, and implementation result is good.
Brief description of the drawings
Fig. 1 is the schematic diagram of apparatus of the present invention.
Embodiment
The present invention makes the equally distributed method of pulp-water in paper machine forming part head box, is to closed headbox casing top
Portion is blown into wind, and uniform blast is applied being covered with above the slurry of casing, pulp-water in paper machine forming part head box is uniformly divided
Cloth.
As shown in figure 1, realizing the device of the inventive method includes slurry tank 1, closed headbox 2, connection slurry tank 1 and
Sending for closed headbox 2 starches pipe 3, is arranged to send and enters stock pump 4 on slurry pipe 3, the blast pipe 5 dried to head box casing top
And it is installed on the low pulse Roots blower 6 on blast pipe.
When apparatus of the present invention work, enter stock pump 4 by the finished product paper pulp in slurry tank 1 by sending slurry pipe 3 to be pumped into enclosed flow
Starch in case 2, the house steward 2a that enters to starch through closed headbox pulp distributor is covered with casing, while starting low pulse Roots blower 6, lead to
The blast that blast pipe 5 is covered with the application stabilization of pulp layer 7 of casing from upper direction is crossed, after making slurry layer thickness and flow velocity uniform, then
Shaping of manufacturing paper with pulp is sprayed to forming net 9 below from grout outlet 8, paper substrate in uniform thickness is obtained.Using low pulse Roots blower
Machine, can prevent air impulsive motion, dissipate gas steady.
The inventive method and device may be directly applied on the closed headbox of existing various papermaking equipments, can be existing
Have and transformed in technical equipment.Equipment therefor is simple in construction, and manufacturing cost is low, is proved through pilot production, can make paper machine forming part
Pulp-water is uniformly distributed in head box, it is ensured that subsequently obtain paper substrate in uniform thickness.
Claims (2)
1. one kind makes the equally distributed method of pulp-water in paper machine forming part head box, it is characterised in that this method is to closing
Formula head box casing top is blown into wind, and uniform blast is applied being covered with above the slurry of casing, starches paper machine forming part stream
Pulp-water is uniformly distributed in case.
2. that realizes method as claimed in claim 1 makes the equally distributed device of pulp-water in paper machine forming part head box, it is special
Levy and be, described device includes slurry tank (1), closed headbox (2), connection slurry tank (1) and closed headbox (2)
Send and starch pipe (3), be arranged to send and enter stock pump (4) on slurry pipe (3), the blast pipe (5) dried to head box casing top and installation
In the low pulse Roots blower (6) on blast pipe.
