Description
Technical field
The invention belongs to paper making equipment field, be specially a kind of long fibre head box and operation process thereof.
Background technology
Head box is the critical component of paper machine, is to link " streaming " and " molding " two-part hinge.For making paper horizontal
The quantitative distribution in width direction is uniform, and evenness is good, it is desirable in head box, slurry is uniformly, be stably distributed, and in slurry, fiber can not be wadded a quilt with cotton
Poly-.To achieve these goals, in the prior art, generally using stepped diffuser to starch rectifier cell as cloth, it acts primarily as
To the effect that cloth slurry, rectification and generation microturbulence dispersion fleeces are poly-, the pulp flow situation of complex flowfield in head box is risen
Vital impact.
But stepped diffuser be applied to produce long stuff paper kind, then there is bigger problem, particularly as follows: with
Time in long fibre head box, long fibre is easily at stepped diffuser, and stopping state occurs in the position such as doctor-roll, thus serious shadow
Ring and produce.
Summary of the invention
In order to solve above-mentioned technical problem, the present invention provides a kind of long fibre head box and operation process thereof, and it is the most real
Now disperse long stuff, it is to avoid the wadding that is deposited in of long stuff amasss；And whitewashing is stable, and produced paper web has been effectively ensured
Quality.
For realizing above-mentioned technical purpose, the concrete technological means that the present invention takes is, a kind of long fibre head box, including

Another object of the present invention is to provide the operation process of a kind of long fibre head box, comprise the steps: that S1 exists
Under powered attendant-controlled wheelchairs effect, one end input slurry relatively low from pulp-inlet pipe position, slurry flows to casing leading portion by stock inlet, and
The most vertically fall the lower end to casing leading portion, and slurry is falling into casing leading portion lower end because being hindered by connected component
Power effect and form turbulence；During persistently inputting slurry, slurry gradually accumulation entrance casing back segment, slurry at connected component
Material plane in casing back segment gradually rises, until concordant with the mouth of pipe of grout outlet；S2 turns on the power mechanism, actuating unit band
Dynamic shaft rotates and realizes the further homogenate to slurry, and last slurry flows out.
Beneficial effect
Utilizing and realize the remove impurity to long stuff into the gravitational difference during slurry, slurry accelerates at gravity after entering casing leading portion
High intensity microturbulent motion can be produced under the effect of degree, it is achieved the dispersion of long stuff, be prevented effectively from the precipitation of long stuff with
Wadding is poly-；And grout outlet is arranged at the upper end of casing back segment and can buffer the fluctuation of long stuff, it is achieved whitewashing is stable, it is ensured that reduction of speed
Coordinate mutually with network speed.
In sum, the product uniformity prepared by long fibre head box of the application is good, the most steady, grammes per square metre height；
The simple in construction of the long fibre head box of the application simultaneously, floor space is little, can be widely used in all kinds of paper industry.

Detailed description of the invention
Purpose and technical scheme for making the embodiment of the present invention are clearer, attached below in conjunction with the embodiment of the present invention
Figure, is clearly and completely described the technical scheme of the embodiment of the present invention.Obviously, described embodiment is the present invention
A part of embodiment rather than whole embodiments.Based on described embodiments of the invention, those of ordinary skill in the art
The every other embodiment obtained on the premise of without creative work, broadly falls into the scope of protection of the invention.
A kind of long fibre head box as shown in accompanying drawing 1-2, including pulp-inlet pipe 1, casing, actuating unit 5, shaft 6；Institute
State casing and include casing leading portion 2, casing back segment 3 and connected component 4；Wherein casing leading portion 2 be arranged in parallel with casing back segment 3, case
The lower end of body leading portion 2 and casing back segment 3 uses connected component 4 to connect, and casing leading portion 2, casing back segment 3 with connected component 4 in double
Layer U-shape structure；In the present embodiment, described casing leading portion 2 is provided with stock inlet in the upper end of one side opposing with casing back segment 3；Described
Pulp-inlet pipe 1 is obliquely installed, and higher one end, pulp-inlet pipe 1 position is that pulp-inlet pipe 1 exports, and pulp-inlet pipe 1 outlet is in entering slurry
Mouthful, and pulp-inlet pipe 1 exports and stock inlet uses rivet to use seal to seal after fixing or being adhesively fixed, pulp-inlet pipe 1
Putting relatively low one end is pulp-inlet pipe 1 entrance, and pulp-inlet pipe 1 entrance is communicated in slurry source；Described casing back segment 3 with casing leading portion 2 phase
The upper end of back of the body one side is provided with grout outlet 7；In order to increase stability, grout outlet 7 uses gusset to be fixed on casing back segment 3 to deviate from casing
The one side of leading portion 2；Described shaft 6 is installed on the internal position closing on grout outlet of casing back segment 3；Described shaft 6 driven type
Being connected to actuating unit 5, and can rotate under the drive of actuating unit 5, the most described shaft 6 is solid hexagonal
Bar structure.Also including supporting leg 8, described casing leading portion 2 and casing back segment 3 all use supporting leg 8 to support.Described actuating unit 5 is arranged
Side in casing back segment 3 upper end.Described actuating unit 5 includes that motor, driven by motor shaft 6 rotate, and shaft 6 turn
Speed is by setting power of motor and speed setting.
A kind of operation process of long fibre head box, comprise the steps: S1 under powered attendant-controlled wheelchairs effect, from pulp-inlet pipe
1 entrance input slurry, slurry goes upward to pulp-inlet pipe 1 by pulp-inlet pipe 1 entrance and exports, simultaneously by the stock inlet of casing leading portion 2
Flowing to casing leading portion 2, and the lower end to casing leading portion 2 that the most vertically falls, slurry is falling into casing leading portion 2 times
After end, the drag effect because of connected component 4 forms turbulence, promotes that long stuff is uniformly dispersed；In the process persistently inputting slurry
In, slurry is gradually accumulated at connected component 4 and is entered casing back segment 3, and the plane that slurry is in casing back segment 3 gradually rises,
Until it is concordant with grout outlet；S2 turns on the power mechanism 5, and actuating unit 5 drives shaft 6 to rotate realize slurry the evenest
Slurry, last slurry is flowed out by grout outlet, and owing to the position of grout outlet is higher, slurry is rising to grout outlet from casing back segment 3
Time, microturbulent motion weakens or disappears, and the stability of pulp is effectively ensured, and then ensure that the product uniformity and grammes per square metre.
These are only embodiments of the present invention, it describes more concrete and in detail, but can not therefore and be interpreted as right
The restriction of the scope of the claims of the present invention.It should be pointed out that, for the person of ordinary skill of the art, without departing from the present invention
