Description
Technical field
The present invention relates to pulping and paper-making station-service equipment technical field, especially waste paper regenerated and shaping pulpboard is the paper mill waters power pulper of raw material.
Background technology
Hydrabrusher is the indispensable key equipment of Pulp And Papermaking Mill, particularly those papermaking producers being raw material with waste paper regenerated and shaping pulpboard, and its status is particularly important.Its blade inswept floor lever of sieve tray when the impeller of hydrabrusher works in prior art, floor lever of sieve tray arranges groove, slurry is easily caused to block sieve aperture and slot, easily foreign material are sticked between steel knife and sieve plate, not only can increase frictional resistance and cause power waste, but also the damage of sieve plate and blade can be aggravated, can cause stuck when foreign material are too much.Blade wear-resisting in prior art is loaded on below blade and plays defibrination effect near sieve plate face, rear bending blade plays a part to promote slurry, but the rag paper slurry that first actual conditions Leaf contacts decline plays a part size degradation slurry, and wear-resisting steel knife just carries out the levigate effect of secondary to the thick slurry after size degradation, this kind of structure causes following problem: one is that blade easily weares and teares; Two is blade weak effects to size degradation slurry, especially those is contained to the waste paper weak effect of glue, can only play and promote the slurry effect of moving ahead.One side by sieve plate below existing hydrabrusher impeller blade is designed with groove and negative relief angle, the relief angle of blade is made to form negative pressure after being intended that the inswept sieve aperture of blade, water below sieve plate is drunk up, thus reach the object of cleaning sieve plate, but because slow-revving impeller institute produces the tiny structure at oblique angle below blade be difficult to the much larger groove inner bucket water static pressure of counteracting, this kind of structure cleaning sieve plate weak effect, sieve aperture easily blocks.Change existing hydrabrusher structure, solve slurry and easily block the problems such as sieve aperture, pulp is few, pulp concentration is low, the hydrabrusher inventing a kind of energy-efficient long service life is significant.
Summary of the invention
The technical problem to be solved in the present invention is to provide that a kind of pulping efficiency is high, pulp concentration is high, the energy-efficient paper mill waters power pulper of long service life.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: comprise kneading trough bucket (1), main shaft (2) is installed in groove bucket inner bottom part central vertical position, main shaft is arranged impeller (3), impeller peripheral groove bottom of the barrel arranges annular sieve plate (4), groove bottom of the barrel corner is welded with curved flow deflector (5), it is characterized in that: the circular web of blade (6) lower plane (7) of described impeller (3) is closed, length of blade and circular web external diameter matched, and it is mutually neat with the internal diameter of annular sieve plate (3), namely impeller blade does not reach on sieve plate face.
Further, described blade makes linear, arranges in ray.
Further, described blade is installed blade (8).
Further, described blade periphery spacing remains on 200-250mm.
Further, the rear bending vanelets (9) of high 5-10mm is welded at the described circular web back side.
The present invention compared with prior art, its advantage is: the present invention is a kind of paper mill waters power pulper, the circular web of impeller blade lower plane is closed, just as the stock pump impeller of an open type, slurry moves and does not contact static groove bottom of the barrel and floor lever of sieve tray completely in impeller channel, will make like this to form negative pressure in impeller channel, impel the slurry opened wide accelerate the blade near impeller and form " pressure " pulping, greatly will improve the speed of pulping thus.Impeller blade does not stretch out floor lever of sieve tray, under certain impeller linear velocity by impeller channel in the slurry energy of flow that throws away to wash away the deposit on sieve plate, sieve aperture pulp is just unblocked, this is because the effect of fluid column static pressure in the slurry stream groove bucket that outwards sprays of impeller, in addition be region with no pressure below sieve plate, the upper and lower pressure reduction of sieve plate can make the slurry stream of the impeller channel ejection exceeding sieve plate change direction, and high velocity slurry stream is close to floor lever of sieve tray flowing, relies on the kinetic energy of slurry self to carry out flush clean sieve plate.To be encrypted by impeller blade and pulping effect can significantly improve after making linear blade into, pulping rate also improves greatly, hydrabrusher of the present invention, because the blade eliminating impeller is inswept floor lever of sieve tray, overcome the subject matter existing for present pulper, particularly process mixed paper slurry advantageously, stop the generation of card foreign material phenomenon between blade and sieve plate completely, pulp is smooth and easy, improve the concentration of slurry, seed output and quality, the life-span of blade and sieve plate also improves greatly, and the power consumption of pulper ton slurry is expected to reduce half.
