Connection, in continuously cooking continuous production process, plank sheathing squeezes friction tearing in continuous flow rate device by helical axis, at the same also to
T shape pipes promote, and the thrust block for generating thrust F1, T shape Guan Shangyou (includes to one opposite force of movement generation at trunnion using cylinder
Power caused by boiling cylinder steam pressure is come from T shapes pipe) F2, the wood of friction tearing has been extruded under the action of F1 and F2
Template is compacted into " material plug " at trunnion, plays sealing function, at the same expect plug continue to push ahead lose bearing after fall into T
In the vertical tube of shape pipe, then falling into boiling cylinder 14, subsequent plank sheathing is promoted by helical axis to be formed new " material plug " and is supplemented,
To realize that the purpose that do not regurgitate with continuous charging, the plank sheathing after becoming smaller are conducive to fast softening after entering boiling cylinder 14, wood
Template is transported to the first mill room 16 after 14 boiling 3-5min of boiling cylinder by the first screw conveyor 15, in the first mill room 16
Cut-out wire-dividing broom purification by grinding forms fiber slurry, and boiling cylinder 14 and first grinds room 16, and there are certain pressure drops by fiber pulp
By 17 force feed of blow-off pipe to jetting storehouse 18, jetting storehouse 18 has the function of eliminating steam pressure and diluted slurry, high temperature liquid
It is for follow-up energy pumping that slurries are diluted one in jetting storehouse 18, and the big centrifugation pumping of concentration is motionless, second is that subsequent filter effect
More preferably, three also for cooling, and slurries enter dump chest 19 after being diluted and cool down in jetting storehouse 18；
The filtering cold grinding device includes that filtering ponds 20, long fine pump remove header box 21, press master 22, the second screw conveyor
23, the second mill room 24, end product pool 25, the slurry of dump chest 19 are screened by filtering ponds 20, and fluff pulp liquid is stored up as papermaking filler
It is stored to end product pool 25, long fibre slurries go header box 21 into press master 22 through long fine pump, and long fine pump goes header box 21 that can make long fine slurry
Liquid even into press master 22, more stablize by the concentration of slurry being extruded in press master 22, and laggard the is concentrated by press master 22
Two screw conveyors 23, then it is delivered to the second mill room 24, long fibre slurries quilt in the second mill room 24 through the second screw conveyor 23
It is stored into after levigate in end product pool 25, the cut-out rear sub-wire brooming in the second mill room 24 by grinding, so as to by high temperature and pressure
Defibrator process does not have levigate slurry to carry out secondary pressure mill so that raw material makes full use of, and improves yield.
Preferably, the decontamination dehydration device further includes inclined wire 5, the water that drum sieve 3 comes out containing the more thin wooden powder,
It is recycled after the screening of inclined wire 5.
A method of papermaking filler is prepared based on above-mentioned novel papermaking filler manufacturing equipment, including：Recycle waste and old building
After plank sheathing, it is processed into the fragment of uniform specification through crusher, is crushed fragmented waste and old construction timber shutterings and is dehydrated by decontamination
Water washing device 2 in device is dehydrated after rejecting impurity 4 in drum sieve 3；
After the pre-heating cabin 12 that 4 dewatered plank sheathing of decontamination is cooked in pressure mill apparatus preheats, steamed in boiling cylinder 14
It boils, the plank sheathing after boiling is sent to mill chamber pressure mill, and pressure grinds the fluff pulp liquid come and is stored into end product pool 25 as papermaking filler
In it is for use, and long fine slurries out remove header box 21 into press master 22 through long fine pump, again into mill room after being concentrated by press master 22,
Long fibre slurries are also stored into end product pool 25 after levigate for use.
After waste and old construction timber shutterings are recovered by the equipment of the present invention, it is processed into the fragment of uniform specification through crusher, breaks
Broken fragmented waste and old construction timber shutterings are dehydrated after rejecting impurity 4 by decontamination dehydration device, the dewatered plank sheathing of decontamination
It is reached in filtering cold grinding device after being cooked pressure mill apparatus boiling pressure mill, fluff pulp liquid is stored into end product pool as papermaking filler
25, long fibre slurries are also stored into end product pool 25 after levigate.The waste and old recovered working process of construction timber shutterings is given birth to as cardboard
The papermaking filler of production is compared with conventional filler, have improve paper machine dewatering, increase sheet thickness, deflection, while with fiber
The binding force feature higher than conventional filler, and the making of this filler can turn waste into wealth, and manufacturing process uses Mechanical Method completely, is not added with
Enter any industrial chemicals, is novel environment-friendly filler.
Several embodiments of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
Cannot the limitation to the scope of the claims of the present invention therefore be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention
Protect range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
