Description
Technical field
The utility model is related to the quetsch of paper industry wet end of machine, and in particular to a kind of headbox dilution water injection
Device.
Background technology
During the online of paper industry wet end paper pulp, the uneven paper of profile basis weight can cause uneven physics
Performance and processing characteristics, so as to cause the failure during production and paper conversion, and cost increase.Therefore, paper
The profile basis weight deviation of page must be effectively controlled, at present using the adjustment of more method profile basis weight deviation
Generally have a two methods with control, one is the adjusting method write music for a song using labial lamina, but this adjusting method exist degree of regulation it is poor,
Adjust the limitations such as sensitivity is low, adjustable range is small.What is more important, paper machine top lip of slice can not keep straight, and slurry stream is in lip
Easily occur the bad fluidised forms such as crossing current, cross-flow at mouthful, not only destroy fiber alignment distribution, can also destroy the consistent of fiber alignment
Property.Second is to use the local concentration by adjusting the horizontal starching stream of paper machine, to control page profile basis weight deviation, this
Kind of method can effectively overcome the shortcomings of that labial lamina is write music for a song regulation method, so major part novel hydropower formula head box is all using dilute at present
Release water and thicken control page profile basis weight deviation, but the method uses device structure complicated.
Utility model content
The purpose of this utility model is to provide a kind of headbox dilution water injection device, to overcome of the prior art ask
Topic, the utility model is simple in construction, dilution water and slurry is uniformly mixed, and then it is inclined to reduce paper cross direction ration
Difference, it is ensured that profile basis weight it is uniform.
To reach above-mentioned purpose, the utility model is adopted the following technical scheme that：
Nozzle, the outside of nozzle and cloth are provided with a kind of headbox dilution water injection device, including cloth slurry pipe, cloth slurry pipe
Formed and interted on suction chamber, cloth slurry pipe provided with the dilution water pipe connected with suction chamber, the outer of suction chamber between the inwall for starching pipe
Mixing tube is connected with, the port of export of mixing tube is connected with anemostat, and the port of export of anemostat is connected to rectification room.
Further, the geometric center of the nozzle, suction chamber, mixing tube and anemostat is conllinear.
Further, the nozzle is the pyramidal structure of tapered diameter, and the taper of nozzle is 13-15 degree.
Further, the anemostat is the pyramidal structure of increasing diameter, and the taper of anemostat is 14-16 degree.
Further, the mixing tube is cylinder.
Further, the dilution water pipe is vertically interspersed on cloth slurry pipe.
Further, two dilution water pipes are vertically interspersed with cloth slurry pipe, and two dilution water pipes are symmetrical arranged.
Further, the arrival end of nozzle is connected to slurry pipe.
Further, it is provided with control valve on dilution water pipe and slurry pipe.
Compared with prior art, the utility model has following beneficial technique effect：
When in use, slurry can produce certain negative pressure to the utility model during mixing tube is entered, using negative
Dilution water is sucked in slurry and mixed while entering mixing tube by the swabbing action of pressure from suction chamber, inner ring during this
What is flowed through is slurry, and what outer ring was flowed through is dilution water, and slurry velocity understands bad student's negative pressure, and then suction dilution water around outer ring,
The mixed effect of both this hybrid mode parallel to axis is good, if purely utilizing the interaction pair between jet and crossing current
Dilution water and slurry are mixed, and can cause mixing apart from long, and this hybrid mode efficiently avoid to inject in crossing current and penetrate
To the influence of crossing current after stream.
Further, by the shape and dimension limitation to nozzle, mixing tube and anemostat, make mixing more uniform.
Further, using symmetrically arranged dilution water pipe, it is ensured that the uniformity of mixing.
Further, the flow of slurry and dilution water can be adjusted by valve.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
Referring to Fig. 1 and Fig. 2, a kind of headbox dilution water injection device, including cloth are starched in pipe 1, cloth slurry pipe 1 and are provided with nozzle
2, the arrival end of nozzle 2 is connected to slurry pipe, and nozzle 2 is the pyramidal structure of tapered diameter, and the taper of nozzle 2 is 13-15 degree,
Formed to intert on suction chamber 3, cloth slurry pipe 1 between the inwall of male cone (strobilus masculinus) and cloth the slurry pipe 1 of nozzle 2 and be provided with what is connected with suction chamber 3
Dilute and two dilution water pipes 4 are vertically interspersed with water pipe 4, cloth slurry pipe 1, and two dilution water pipes 4 are symmetrical arranged, suction chamber 3
Outer is connected with the mixing tube 5 of cylinder, and the port of export of mixing tube 5 is connected with anemostat 6, and anemostat 6 is the cone of increasing diameter
Shape structure, and the taper of anemostat 6 is 14-16 degree, the port of export of anemostat 6 is connected to rectification room 7, the nozzle 2, suction chamber
3rd, the geometric center of mixing tube 5 and anemostat 6 is conllinear, and control slurry flow is respectively arranged with dilution water pipe 4 and slurry pipe
With the valve of dilution water flow.
Implementation process of the present utility model is described in further detail below：
The technology that the utility model is used is fluidics, and the negative pressure produced using slurry stream by nozzle 2 will dilute water pipe 4
