Description
Technical field
The utility model relates to a kind of fiberizer, is specifically related to the cylinder fiberizer in a kind of Shuan Mo of having district, is applicable to that the defibrination of paper pulp magma in the paper industry and secondary stock is handled, and belongs to the pulping and paper-making field.
Background technology
At present, the widely used fiberizer in pulping and paper-making field comprises two kinds of double disc refiner and conical refiners, Fig. 1 and Fig. 2 have showed the stress model in these two kinds of paste mill grinding districts respectively, the both sides dash area is represented moving abrasive disc respectively and is decided abrasive disc, carry out initial analysis as can be known by stress model: (1), in the defibrination district of double disc refiner, paper pulp flows along the direction of centrifugal action, and the linear velocity in defibrination district therefrom mind-set cylindrical changes from small to large, and this will cause the defibrination quality inhomogeneous; (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 approaches 90 ° more, then the pulp flow direction approaches the direction of centrifugal force more, its defibrination quality has a certain upgrade with respect to double disc refiner, but does not still reach gratifying effect, and the job stability of conical refiner also is a big problem that allows the people perplex in addition.
The defibrination quality is one of standard of passing judgment on by fiberizer, and in addition defibrination efficient and no-load power consumption also are to weigh the important techniques economic and technical norms of fiberizer.
Wherein, the defibrination efficiency eta is meant the ratio of defibrination effective power and general power: η=Pe/P * 100%, Pe consumes (kW) for defibrination effective power in the formula, and P is defibrination total power consumption (kW), and the effective power that is consumed during defibrination is decided by the contact area and the rotating speed of mill.The contact area of mill is big more, and rotating speed is high more, and then the effective power of Xiao Haoing is just big more.So wanting to improve the defibrination efficiency eta can go to set about from the contact area that increases mill.
Can access no-load power consumption formula: P from the fiberizer field investigation
1=k * n
3* R
5, P in the formula
1Be no-load power consumption (kW) that the coefficient of k express liquid density and local frictional force is subjected to the influence of fiberizer and paper pulp type and changes, 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 more little, and no-load power consumption P so
1Just more little, this also is an improvement thinking of fiberizer.
To sum up, the defibrination quality and the defibrination efficient 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.
The utility model content
