Description
Technical field
The utility model relates to a kind of decatize storehouse, is specifically related to a kind of decatize storehouse for chemical-mechanical pulping.
Background technology
During chemical-mechanical pulping extrusion impregnating, for reducing fragment and flooding evenly, wood chip is needed well to soften, improve wood chip plasticity, wood chip temperature and moisture are its important factor in order, and wood chip moisture is high, wood chip softening temperature is lower, moisture and the higher then bating effect of temperature better; Containing portion of water, air, water miscible coloring matter and resinous substances in wood chip chemical constituent, first water miscible coloring matter and resinous substances can consume chemicals and affect bleaching effect.Good squeezing effect, effectively can remove these harmful substances with moisture before chemicals adds.
Therefore before extrusion impregnating, pulping raw material such as wood chip presteaming is an important pulping process, this procedure completes usually in decatize storehouse, play following Main Function: by steam decatize, heating wood chips, remove the air in wood chip, wood chip is softened, is conducive to reducing fragment in postorder extrusion impregnating process and flooding evenly; The moisture content of balanced wood chip and temperature, moisture and portfolio effect directly affect the removal efficiency of water miscible coloring matter and resinous substances in postorder extrusion impregnating technique; And the holdup time of wood chip abundance is provided; When wood chip short interruption, also as a buffer container, guarantee to provide even, controlled wood chip to system, to maintain the stable of production.
Existing decatize storehouse like product warehouse profile is the housing that a bottom is upright, conical cover is arranged at top, middle and lower part is connected to steam pipe, storehouse tail band has an oscillatory type discharge unit, bottom is defluent skewed slot completely, wood chip enters the discharge device under it by feeding here, because each volume turned of metering screw is certain in discharge device, the volume flow of wood chip can be known by the revolution of metering screw, by bulk density and the volume flow calculating output of wood chip.
But the structural design capacity utilization rate in existing decatize storehouse and material fullness rate lower, cause stop steaming time in material bin short, decatize is softened, moisture equilibrium and buffering effect reduce, wood chip is softening not enough, for postorder extrusion impregnating process, while reducing extruding and dipping effect, reduce the removal efficiency of water-soluble coloring matter and resinous substances, thus the chemical cost amount of chemical treatment must be increased, especially the consumption of bleaching chemicals, this problem is along with the reduction year by year of the pulping raw material quality such as domestic goods wood chip, affect more and more outstanding.Meanwhile, wood chip is heated and can produces volumetric expansion, and when in storehouse, material level is higher, in compaction state between wood chip, after expanded by heating, compaction degree is more closely knit, very easily produces arch formation, and easy blanking does not freely produce blocking.
