Description
Technical field
The present invention relates to paper making equipment technical field, more particularly to a kind of paper product production headbox apparatus.
Background technology
Paper refers to the sheet-like fiber product for writing, printing, paint or pack etc., with the transition in epoch, people couple
All changing in the demand and demand mode of paper constantly, production of paper products processing equipment also in synchronized update,
Head box is a key device of paper machine, and key effect is played for the good page of mass of manufacturing paper with pulp, head box
One basic task is to ensure that fibrous suspension is uniformly distributed along paper machine cross, to reduce the horizontal quantification of page as much as possible
Difference, another basic task of head box is to ensure that the fiber in fibrous suspension is dispersed in water body, is reduced as far as possible fine
Tie up the wadding agglomerate in suspension, to improve the evenness of page as far as possible, but traditional head box in actual use due to water filling
Stirring easily internally produces bubble, influences the purity of paper pulp and the quality of paper product, and headbox apparatus is mixed in progress fiber
Paper pulp fiber can be caused to waste if water filling dilution can produce spill-over phenomenon, no removal process when dynamic, add paper product
Manufacturing cost, while can not accurately and efficiently be controlled when being changed to cross direction ration, is easily caused labial lamina deformation,
Therefore traditional headbox apparatus in actual use in the presence of many limitations, therefore, it is proposed that a kind of production of paper product is used
Headbox apparatus.
The content of the invention
It is a primary object of the present invention to provide a kind of paper product production headbox apparatus, by turbulent flow generator side
Froth breaking net is set, and pressurization is carried out to flowing water using turbulent flow generator mixes dynamic regulation, can prevent fiber precipitation and wad a quilt with cotton again poly- and sharp
Bubble is destroyed with grid pressure, it is ensured that the purity of pulp-water and the quality of post-production, overflow by being set in casing side
Stream pond simultaneously connects overflow pipe, and the pulp-water of spill-over is dredged by the overflow pipe of casing both sides and overflow launder is recycled to, can
Precipitated using overflow launder or directly recycling etc., the saving of resource is realized, by between top lip of slice and aulaeum
Labial lamina regulating valve is set, and dilution water valve is set in dilution supply mains one end, horizontal stroke of the labial lamina regulating valve to head box can be utilized
Width is quantitatively adjusted, and is unlikely to deform labial lamina, while side stream regulation is carried out inside water valve convection current slurry case using diluting, to compensate
Both sides are quantified, the problem of effectively can solving in background technology.
To achieve the above object, the technical scheme taken of the present invention is：
A kind of paper product production headbox apparatus, including housing, enter to starch house steward, dilution supply mains, cloth slurry Taper Pipe and run-off, institute
Shell one end is stated to be provided with into slurry house steward, it is described to enter to starch inner manifold and be provided with dilution orifice plate, dilution orifice plate one end connection
There is a multistage tube bank, described to enter to starch house steward side and be provided with balance cylinder, described balance cylinder one end is connected with turbulent flow generator, the rapids
Flow-generator side is provided with froth breaking net, and the froth breaking net both sides are provided with doctor-roll, and the housing other end is connected with cloth
Taper Pipe is starched, the cloth slurry Taper Pipe both sides are connected to top lip of slice and aulaeum, and it is total that the top lip of slice side is provided with dilution water
Pipe, the housing side is provided with overflow pipe, and described overflow pipe one end is connected with run-off.
Further, the housing is the housing of stainless steel.
Further, described dilution supply mains one end is provided with dilution water valve.
Further, it is provided with labial lamina regulating valve between the top lip of slice and aulaeum.
Further, the housing side is connected with slurry flow export.
Further, hollow structure is in the doctor-roll inside and is specifically provided with two groups.
Compared with prior art, the present invention has the advantages that：
1st, by setting froth breaking net in turbulent flow generator side, disperse in actual paper fiber in flow, due to box house
A large amount of water sources are filled with, and the mixed dynamic regulation of pressurization is carried out to flowing water using turbulent flow generator, box house current is constantly in
Microturbulent motion state, can prevent fiber precipitation and wad a quilt with cotton again it is poly-, but its work while due to pulp-water more it is close it is thick it is easy produce
Bubble, the generation of bubble makes effect when purity and the effect of pulp-water be affected, by setting froth breaking net to utilize grid
Pressure is destroyed to bubble, it is ensured that the purity of pulp-water and the quality of post-production.
2nd, by setting run-off in casing side and connecting overflow pipe, when headbox apparatus is run sometimes because dilute
The more formation spill-over phenomenon of water water injection rate is released, and passes through casing still containing a large amount of available paper fibers in dilution water
The overflow pipe of both sides is dredged the pulp-water of spill-over and is recycled to overflow launder, can be precipitated or directly returned using overflow launder
Recycling etc. is received, makes the utilization to paper fiber more abundant, embodies environmental protection concept.
3rd, by setting labial lamina regulating valve between top lip of slice and aulaeum, and dilution water is set in dilution supply mains one end
Valve, can be adjusted to the cross direction ration of head box using labial lamina regulating valve, be unlikely to deform labial lamina, while utilizing dilution water
Valve carries out side stream to head box inside and adjusted, and is quantified with compensating both sides, prevents from too small or excessive causing the dew of surface layer because quantitative
Bottom phenomenon produces disconnected paper because water content is high.
