1, the invention patent in use, by the flow rate stable using limitation buffer control stalk, makes waterpower
Rice wheat straw waste concentration in grass chopper keeps in a certain range, being dehydrated using inclined helix dehydrator, enters rub with the hands later
Silk machine, the input and output material of thread rolling machine are balanced, and discharge hole for discharge stability of flow, feed inlet is without delay.Stable flow rate
It ensure that the stabilization of high pressure and high temperature inside thread rolling machine.Stalk makes during the positive and negative rotor of thread rolling machine rubs mill with the hands repeatedly
Also high temperature and pressure is produced while rice wheat straw waste becomes not only thin but also small is sufficiently submerged in hot water moment in swelling state rice
In wheat straw waste, makes its softening, curing, reach 42-52 Kappa number of hardness number of theory calls.Actually detected Kappa number is
36—40.Because flow velocity is stablized without interruption and suddenly big or suddenly small process, its global theory data are fixed.
Softening curing can be continued to by following three kinds of technique by the tiny stalk that thread rolling machine comes out: (one) is due to curing, softening
Process deadline moment is short, prevents its retrogradation.Existing: stalk enters feed back spiral, dosing spiral boiling after coming out from thread rolling machine
Pipe etc., Kappa number in front of dense pump are 39-42, and actual measurement Kappa number is 40.9, can enter within the shortest time in dense mill,
Tiny stalk fibre, being turned into fiber again by another stranding mill stalk experienced primary curing softening process Kappa number
Being in stable state can not restore.After squeezed into pond or tank through stock pump and kept for the regular hour.This technique root
Next procedure can also be directly entered according to the requirement of paper to be not required to stop.(hardness 42-45 Kappa number, measured hardness is slurried in theory calls
36-40 Kappa number) (two) filter out the tiny stalk come out from thread rolling machine water by extrusion equipment and keep certain concentration, adjust
Good flow rate is rubbed with the hands through second of thread rolling machine and is ground.After pass through in dense pump squeeze into pond or tank and kept for the regular hour.(3)
If 200 tons of rice wheat straw wastes of processing daily, are ready for five storage tanks or pond, each tank or tankage are 50 tons of (pure slurries
Amount).Rice wheat straw waste dense pump can be pumped directly into immersion oxidation in storage tank or pond in after coming out from thread rolling machine, and 8--24 hours
After be recycled.(water quality difference impregnate time it is also different, survey same water quality after 12 hours Kappa number be 35.1,24 hours
Actually detected Kappa number is 28-32 afterwards, and straw pulp shifts to an earlier date shift production.) so far realize the purely mechanic system of rice wheat straw waste
Slurry.The invention patent chief is by the high temperature and pressure for rubbing mill generation with the hands repeatedly of the positive and negative rotor of thread rolling machine rice and kernel grass straw
Stalk cures, becomes smaller, attenuates, and can reach theoretic requirement using tank or pond immersion regular hour.
2, the present invention compared with existing it save a large amount of equipment investment, it has discarded traditional equipment such as feed back spiral shell
Rotation, dosing spiral sell the equipment such as drum metering, boiling pipe, buffer unloading device, single-screw press master, it has discarded all chemistry
Material and equipment such as drug storage tank, drug ratio tank, black liquor recovery tank, black liquor filter, drug regenerating tank etc..It is not only saved
It has saved a large amount of equipment investment and has also saved a large amount of equipment and occupied space and a large amount of electricity consumption and labour cost.
