Description
Technical field
The present invention relates to a kind of fiberizer, be specifically related to a kind of cylinder fiberizer with Shuan Mo district, be applicable to the defibrination process of paper pulp magma in paper industry and secondary stock, belong to pulping and paper-making field.
Background technology
At present, the widely used fiberizer in pulping and paper-making field comprises double disc refiner and conical refiner two kinds, Fig. 1 and Fig. 2 respectively show the stress model in this Liang Zhong paste mill grinding district, both sides dash area represents dynamic abrasive disc respectively and determines abrasive disc, initial analysis is carried out: (1), in the defibrination district of double disc refiner from stress model, paper pulp flows along the direction of centrifugal action, the linear velocity in defibrination district from center outwards circle change from small to large, this will cause defibrination quality uneven; (2), in the defibrination district of conical refiner, because mill has tapering, the direction of pulp flow constantly changes along with the component effect of centrifugal force, tapering is more close to 90 °, then pulp flow direction is more close to the direction of centrifugal force, its defibrination quality has a certain upgrade relative to double disc refiner, but does not still reach gratifying effect, and the job stability of conical refiner is also the large problem allowing people perplex in addition.
Defibrination quality is one of standard passing judgment on fiberizer, and in addition defibrination efficiency and no-load power consumption are also weigh the important Technological Economy technical indicator of fiberizer.
Wherein, defibrination efficiency eta refers to the ratio of defibrination effective power and general power: η=Pe/P × 100%, in formula, Pe is that defibrination effective power consumes (kW), P is defibrination total power consumption (kW), and the effective power consumed during defibrination is decided by contact area and the rotating speed of mill.The contact area of mill is larger, and rotating speed is higher, then the effective power consumed is larger.So wanting to improve defibrination efficiency eta can go to set about from the contact area increasing mill.
No-load power consumption formula can be obtained: P from fiberizer field investigation
1=k × n
3× R
5, P in formula
1for no-load power consumption (kW), the coefficient of k express liquid density and local friction, by fiberizer and paper pulp type impact and change, n is speed of grinding plate (r/h), and R represents mill rotor radius (m).Thus, we are not difficult to find: under same defibrination ability, if rotor radius R is less, so no-load power consumption P
1less, this is also an improved though of fiberizer.
To sum up, defibrination quality and the defibrination efficiency of existing fiberizer are all not fully up to expectations, need the fiberizer that a kind of performance is more excellent, economic benefit is outstanding.
Summary of the invention
For solving the deficiencies in the prior art, the object of the invention is to the defect overcoming prior art, a kind of cylinder fiberizer with Shuan Mo district is provided, defibrination quality is high and defibrination is in stable condition, improves the performance of paper pulp, and compares with conical refiner with traditional double disc refiner, defibrination efficiency is high, under same defibrination ability, no-load power consumption significantly reduces, remarkable in economical benefits.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
