Technical field
The present invention relates to pulp technology for making paper, and in particular to a kind of bamboo pulp unbleached paper refining equipment.
Background technique
Currently, toilet paper papermaking much carries out defibrination, the raw material that common toilet paper papermaking is used substantially using double mill machines
It is waste paper, wheat straw, reed, sugarcane, timber etc., double mill machines generally all include a rotary grinding disk and fixed millstone, raw material mixing
Rubbing is carried out between rotary grinding disk and fixed millstone after certain water to discongest, and fibre bundle in raw material is allowed to be divided into thin single fiber.
But the raw material that bamboo pulp unbleached paper uses is bamboo, these are normal much higher than wheat straw, reed and sugarcane for the hardness of bamboo
With raw material, longer using existing double mill machine defibrination times, fiberizer service life shortens；In addition, due to bamboo during defibrination
Subbundle length is longer, and thicker fibrous raw material is difficult to enter in the slot of mill, and few fibers raw material is caused to rest on always
Around mill, defibrination is obviously uneven.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of bamboo pulp unbleached paper refining equipments, improve the defibrination uniformity of bamboo pulp.

The degree of dissection for promoting bamboo raw material, allows fibre bundle to be more exposed, moreover it is possible to and avoid fibre bundle from excessively being cut in corase grinding interior,
It allows fibre bundle having time to absorb moisture and improves flexibility.When fibre bundle enters two abrasive disk spaces along roll flute again, by mill spindle
It is bent to extruding, is able to ascend the separation of fiber in fibre bundle in this way, promote beating degree.
Further, size of the through-hole in corase grinding room one end is greater than the size in defibrination room one end.Avoid more slurry from
Through-hole returns to corase grinding room, promotes the inlet amount for roughly grinding room to defibrination room.
Further, being also rotatably connected in defibrination room can be to the helical blade of rotary grinding disk loopback slurry.It avoids from two
The farther away slurry of mill is trapped in always defibrination room corner, and helical blade can promote the flowing of slurry in defibrination room, allows defibrination
More evenly.
Further, the driving device uses cylinder.The motion bar of cylinder is flexible braking, and opposite motor, centre is not required to
Other drive mechanisms are set, capacity usage ratio is promoted.
Further, corase grinding room is equipped with feed inlet.Convenient for bamboo raw material is added to corase grinding room.
Further, corase grinding room includes corase grinding section and flared section, roughly grind section and flared section be it is round table-like, corase grinding section radius is small
