Abstract
The invention discloses a separating and controlling device for a mixing and balancing chamber of a head box. The device is arranged between a pulp inlet pipe bundle and a turbulence generator and consists of a plurality of separated mixing and balancing chambers; a plurality of partition boards are transversely and uniformly arranged between an orifice plate of the pulp inlet pipe bundle and an orifice plate of the turbulence generator, a cavity between two neighboring partition boards forms a separated mixing and balancing chamber, and 2-5 rows of pulp inlet pipe bundles are arranged on the orifice plate of the pulp inlet pipe bundle of the inlet end of the separated mixing and balancing chamber; and a balance hole is opened in the middle of each partition board. The concentration of the pulp is adjusted by dilution water and then the diluted pulp enters the separated mixing and balancing chamber from the 2-5 rows pulp inlet pipe bundle, and is mixed in a small separated mixing and balancing chambers, thus effectively reducing the large-scale transverse turbulence of the pulp in the mixing and balancing chamber and improving the accuracy of the dilution water of the head box in adjusting the transverse quantitative distribution positions of the paper; the small balance hole on each partition board can balance the pulp flow pressure between two neighboring separated mixing and balancing chambers.
Description
Technical field
The present invention relates to the pulp and paper technology field, particularly relate to and a kind ofly control the head box combined balance system device that slurry mixes, can improve the accuracy that the head box dilution water is regulated page horizontal quantification distributing position by a plurality of combined balance chambers of independently separating.
Background technology
The means that the page of high speed paper machine adjusting at present horizontal quantification distributes generally are to realize by adding dilution water local modulation slurry concentration in head box.In the existing known dilution water head box, its combined balance chamber all is a monoblock type.The slurry of every row pulp-inlet pipe bundle is quantitative according to the correspondence position page, utilizes the interpolation dilution water to regulate its correspondence position slurry concentration.After the slurry of regulating concentration through dilution water enters the monoblock type combined balance chamber from the pulp-inlet pipe bundle, because between every tubulation bundle and the pressure imbalance between the horizontal front and back position of head box, the quantitative slurry in original this position of control, because pressure height, slurry is laterally gone to the low position of pressure, cause slurry a large amount of and laterally turbulence on a large scale in the monoblock type combined balance chamber, it is inaccurate to make dilution water regulate page horizontal quantification distributing position.
Summary of the invention
For causing dilution water, the monoblock type combined balance chamber that overcomes existing head box regulates the inaccurate deficiency of page horizontal quantification distributing position, the invention provides a kind of separation control device of head box combined balance chamber, can reduce slurry stream in the indoor a large amount of and laterally turbulence on a large scale of combined balance system, improve the accuracy that the head box dilution water is regulated page horizontal quantification distributing position.
Purpose of the present invention is achieved through the following technical solutions:
A kind of separation control device of head box combined balance chamber is installed between pulp-inlet pipe bundle and the turbulent flow generator, is made up of a plurality of separation combined balance chambers; Separating combined balance chamber is made up of pulp-inlet pipe beam hole plate, turbulent flow generator orifice plate, demarcation strip; The polylith demarcation strip laterally evenly is installed between pulp-inlet pipe beam hole plate and the turbulent flow generator orifice plate at interval, the cavity that per two demarcation strips are separated forms one and separates combined balance chamber, and the pulp-inlet pipe beam hole plate of separating the combined balance chamber entrance point is provided with 2～5 row pulp-inlet pipe bundles; Open a balance pipe in the middle of the every demarcation strip.
The spacing of described demarcation strip is preferably 100mm to 500mm.
Described described balance pipe diameter is preferably 10mm to 30mm.
With respect to prior art, the present invention has following advantage and beneficial effect:
The present invention adopts the separation mixed method, regulate the slurry of concentration through dilution water, enter the separation combined balance chamber from 2～5 row pulp-inlet pipe bundles, in independently little separation combined balance chamber, mix, effectively reduce slurry stream in the indoor a large amount of and laterally turbulence on a large scale of combined balance system, improve the accuracy that the head box dilution water is regulated page horizontal quantification distributing position; The little balance pipe of every demarcation strip is separated combined balance chamber with each and is communicated with, and makes the pressure of slurry stream between the adjacent separation combined balance chamber reach balance.

Shown in the figure, 1. advance to starch house steward, 2. dilution water system, 3. pulp-inlet pipe bundle, 4. pulp-inlet pipe beam hole plate, 5. separation combined balance chamber, 6. turbulent flow generator orifice plate, 7. turbulent flow generator, 8. balance pipe, 9. demarcation strip.
The specific embodiment
For further understanding the present invention, below in conjunction with accompanying drawing the present invention is further described, need to prove that the specific embodiment is not construed as limiting the scope of protection of present invention.
As shown in Figure 1, 2, 3, the separation control device of head box combined balance chamber of the present invention is installed between pulp-inlet pipe bundle 3 and the turbulent flow generator 7, is made up of a plurality of separation combined balance chambers 5.Separating combined balance chamber 5 is made up of pulp-inlet pipe beam hole plate 4, turbulent flow generator orifice plate 6, demarcation strip 9.Demarcation strip 9 laterally evenly is installed between pulp-inlet pipe beam hole plate 4 and the turbulent flow generator orifice plate 6 at interval, and the cavity that per two demarcation strips 9 are separated forms one and separates combined balance chamber 5, and all-in-one-piece combined balance chamber is separated into a plurality of little combined balance chambers.The pulp-inlet pipe beam hole plate 4 of separating combined balance chamber 5 entrance points is provided with 2～5 row pulp-inlet pipe bundles 3, and the quantity of demarcation strip 9 is according to the quantity decision of head box pulp-inlet pipe bundle 3, and its spacing is 100mm to 500mm.
Fig. 3 is a structural representation of separating combined balance chamber, opens a little balance pipe 8, diameter 10mm to 30mm in the middle of every demarcation strip 5.
Regulate the slurry of concentration through dilution water, enter separation combined balance chamber 5 from 2～5 row pulp-inlet pipe bundles 3, in independently little combined balance chamber, be mixed into uniform slurry stream, mixed slurry flows to into turbulent flow generator 7, so just can reduce slurry stream separating a large amount of and laterally turbulence on a large scale between the combined balance chamber 5, improve the accuracy that the head box dilution water is regulated page horizontal quantification distributing position.For the pressure imbalance of slurry stream between the adjacent separation combined balance chamber 5 of balance, in the middle of every demarcation strip 9, open a little balance pipe 8 simultaneously, each is separated combined balance chamber 5 be communicated with, make the pressure of slurry stream between the adjacent separation combined balance chamber reach balance.
With respect to prior art, the present invention has following advantage and beneficial effect:
The present invention adopts the separation mixed method, the slurry of regulating concentration through dilution water mixes in independently little separation combined balance chamber, effectively reduce slurry stream in the indoor a large amount of and on a large scale laterally turbulence of combined balance system, improve the accuracy that headbox dilution water is regulated page horizontal quantification distributing position.
