Abstract
One kind makes the equally distributed device of 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 utility model can be uniformly distributed pulp-water in paper machine forming part head box, to obtain paper substrate in uniform thickness.
Description
Technical field
The utility model 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 is had a great influence 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
The house steward that enters to starch use square taper return duct, pulp-water is evenly distributed to forming net below by interior pressure caused by pumping
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 because square taper backflow overpressure can change with the pressure change for entering stock pump, build-up of pressure is unstable, influences starching
The uniformity.
The content of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, there is provided one kind can starch paper machine forming part stream
Pulp-water is uniformly distributed in case, to obtain the device of paper substrate in uniform thickness.
The purpose of this utility model is achieved through the following technical solutions：
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 utility model device, stable wind is blown into head box casing top, the pulp layer of casing can be covered with
Top forms stable blast, even if the pressure in square taper return duct is entered slurry pump pressure change and causes unstable, but passes through
Square taper return duct enters the slurry in casing under the Action of Wind pressure of top homogeneous constant, still can uniformly spread out, and protects
Hold uniform thickness, it is ensured that into the slurry stable and uniform of rear portion forming net, production obtains paper substrate in uniform thickness.This practicality is new
Type is skillfully constructed, and device is simple and reliable, can directly be transformed on prior art device, and manufacturing cost is low, and implementation result is good.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model device.
Embodiment
As shown in figure 1, the utility model includes slurry tank 1, closed headbox 2, connection slurry tank 1 and enclosed flow slurry
Case 2 send slurry pipe 3, be arranged at send slurry pipe 3 on enter stock pump 4, to head box casing top dry blast pipe 5 and be installed on into
Low pulse Roots blower 6 on airduct.
The utility model is applied by being blown into wind to closed headbox casing top being covered with above the slurry of casing
Even blast, it is uniformly distributed pulp-water in paper machine forming part head box.During work, enter stock pump 4 by the finished paper in slurry tank 1
Slurry is by sending slurry pipe 3 to be pumped into closed headbox 2, and the house steward 2a that enters to starch through closed headbox pulp distributor is covered with casing, together
Shi Qidong low pulses Roots blower 6, the pulp layer 7 for being covered with casing from upper direction by blast pipe 5 apply stable blast, made
After slurry layer thickness and flow velocity are uniform, then spray to shaping of manufacturing paper with pulp on forming net 9 below from grout outlet 8, it is uniform to obtain thickness
Paper substrate.Using low pulse Roots blower, air impulsive motion can be prevented, it is steady to dissipate gas.
The utility model may be directly applied on the closed headbox of existing various papermaking equipments, can be in prior art
Transformed in equipment.Equipment therefor is simple in construction, and manufacturing cost is low, is proved through pilot production, can make paper machine forming part head box
Interior pulp-water is uniformly distributed, it is ensured that subsequently obtains paper substrate in uniform thickness.
