Description
Technical field
The utility model belongs to pulping and paper-making field, is related to a kind of pulp dilution device, more particularly to a kind of middle-size and small-size slurry
The paper pulp reflux dilution device of tower.
Background technology
In pulping and papermaking processes, the preparation storage of paper pulp and streaming be in a necessary links, pulp preparing process often
Make it that paper pulp fiber is fully absorbed water swollen, the swollen time is general in more than 12h, in addition for highly concentrated or low dense kowtow slurry
Pair etc. link often in electricity consumption slack hours section, therefore actual production demand is met, it is necessary to there are enough slurry deposits, i.e.,
Substantial amounts of pulp storage turns into a key issue, and traditional storage slurry equipment uses common in stock tank, such as industry copy
Forebay, the general 5m of its height or so, using stock tank the biggest advantage is that paper pulp is well mixed, propeller power is smaller then can
The relatively low but fatal weakness of consumption is that its capacity is small and floor space is big, and this makes to present most high speed, high production capacity
Production requirement can not be preferably met for paper machine again；Then exploitation devises slurry tower apparatus as shown in Figure 1 on this basis,
More than 15m is up to for large-scale slurry tower tower body, high below the 15m of tower body is middle-size and small-size slurry tower, slurry tower capacity is big, floor space is small,
And can effectively overcome the related vulnerability of traditional stock tank, but be due to that the design feature for starching tower also brings disadvantage to practical application
End：Slurry tower tower body is relatively high so that upper hypostome in the phenomenon that wadding gathers lower leaf, figure is produced in slurry tower by the paper pulp of swollen
From light to dark, upper strata is sparse water layer to color, and lower floor is intensive pulp layer, so as to starch in tower, concentration is different above and below paper pulp, influences paper pulp
Uniform mixing, or even for some slurries kind, lower floor's excessive concentration can cause paper pulp mixing to pump difficulty, while propeller power
It is higher, energy consumption is also increased, even middle-size and small-size these problems of slurry tower also have obvious performance.Therefore, slurry tower is preferably solved
The drawbacks described above that own characteristic is brought, plays the advantage of slurry tower, has its important paper-making process and energy-saving grade well
Meaning.
