Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Learn from Fig. 1 to Fig. 5, the acceleration polymer swollen particle dissolution device of this band cleaner and instant ring is by cleaner 19, draw unit and liquid storage cylinder 1 form, draw unit top is the cleaner 19 be fixed on power transmission shaft 6, described cleaner 19 is made up of multiple impellers, draw unit is by upper fixed tooth disk 3, active toothed disk 4, lower fixed tooth disk 5, power transmission shaft 6, bearing block 7 forms, cleaner 19 bottom is followed successively by the upper fixed tooth disk 3 all with some through holes 2, active toothed disk 4, lower fixed tooth disk 5, described upper fixed tooth disk 3, active toothed disk 4, lower fixed tooth disk 5 is formed by connecting by some groups of waney concentric circles gear rings, the concentric circles gear ring of described active toothed disk 4 and upper fixed tooth disk 3, the concentric circles gear ring of lower fixed tooth disk 5 is evenly engaged, upper fixed tooth disk 3 and lower fixed tooth disk 5 are fixed on liquid storage cylinder 1, active toothed disk 4 is fixed on power transmission shaft 6, power transmission shaft 6 is connected belt pulley 9 by bearing block 7 with liquid storage cylinder 1, bearing block 7 is fixed on liquid storage cylinder 1, draw unit is positioned at liquid storage cylinder 1, liquid storage cylinder 1 top is provided with inlet 10, bottom is provided with liquid outlet 11.
During use, as Fig. 1 to Fig. 5, first arrange and this acceleration polymer swollen particle dissolution device external motive device, make belt pulley 9 drive power transmission shaft 6, thus active toothed disk 4 is rotated.The aqueous solution of not consoluet hydrophobic associated polymer enters liquid storage cylinder 1 from the inlet 10 of upper cover 12, the aqueous solution of hydrophobic associated polymer is through cleaner 19, then upper fixed tooth disk 3 and active toothed disk 4 is entered from through hole 2 successively, driven fluted disc 4 enters lower fixed tooth disk 5 again, because upper fixed tooth disk 3, active toothed disk 4 and lower fixed tooth disk 5 all adopt concentric circles gear ring, this gear ring adopts short tooth 8 structure, the concentric circles gear ring of active toothed disk 4 is evenly engaged with the concentric circles gear ring of upper fixed tooth disk 3, lower fixed tooth disk 5, thus forms instant structure ring.Short tooth 8 structure upper on the concentric circles gear ring of lower fixed tooth disk 3 and active toothed disk 4 is trapezoidal, upper fixed tooth disk 3 is engaged spacing 13 with active toothed disk 4, active toothed disk 4 and lower fixed tooth disk 5 and reduces gradually from top to bottom, and active toothed disk 4 is with the rotation speed operation of 1400rpm, so the swellable particles of hydrophobic associated polymer in the aqueous solution of hydrophobic associated polymer is rolled expansion by short tooth 8 structure, form the swellable particles that particle diameter is less.Processed swellable particles, by liquid outlet 11, enters into the pipeline be connected with slaking tank, finally enters into slaking tank and dissolve.
Power transmission shaft 6 bottom and the mechanical seal 14 set by bearing block 7 centre prevent the solution of liquid storage cylinder 1 li enter power transmission shaft 6 thus corrode power transmission shaft 6, and the centralizer 15 be fixed on bearing block 7 set by mechanical seal 14 outside, can prevent power transmission shaft 6 from rocking and skew.
Fig. 2 is the top view of the active toothed disk of the acceleration polymer swollen particle dissolution device of this band cleaner and instant ring, active toothed disk 4 is driven by power transmission shaft 6 and operates, the swellable particles of hydrophobic associated polymer is rolled expansion by short tooth 8 structure, form the swellable particles that particle diameter is less, flow out from through hole 2.
Fig. 3 is the short toothing amplification profile on the concentric circles gear ring of the upper fixed tooth disk of the acceleration polymer swollen particle dissolution device of this band cleaner and instant ring, active toothed disk, lower fixed tooth disk.The upper dynamic tooth 17 determining tooth 16 and active toothed disk 4 of upper fixed tooth disk 3 forms the instant structure of one-level, upper determine tooth 16 and dynamic tooth 17 and be mutually engaged and have and be engaged spacing 13, its occlusion spacing 13 upper entrance is 2.45mm, and occlusion spacing 13 lower part outlet is the degree of depth of 0.45mm, its 0.45mm is 5mm.The dynamic tooth 17 of active toothed disk 4 is determined tooth 18 with the lower of lower fixed tooth disk 5 and is formed the instant structure of secondary, dynamic tooth 17 and determine tooth 18 and be mutually engaged and have and be engaged spacing 13 down, its occlusion spacing 13 upper entrance is 1.32mm, and occlusion spacing 13 lower part outlet is the degree of depth of 0.15mm, its 0.15mm is 5mm.By above bipolar instant structure, can make swellable particles force stretch, obtain the swellable particles that particle diameter is less, its effect than only have a fixed tooth disk and active toothed disk good.
Fig. 4 is the top view of the cleaner of the bipolar acceleration polymer swollen particle dissolution device of this band cleaner, and cleaner 19 is fixed on power transmission shaft 6, and under the drive of motor, wheel rotation, can clear up the polymers swell particle on fixed tooth disk 3.Because can be attached to when polymers swell particle is large on upper fixed tooth disk 3, the through hole 2 that can block on fixed tooth disk 3 affects the normal operation of device or lowers efficiency, now cleaner 19 operates under the drive of power transmission shaft 6, polymer attached swellable particles in cleaning on fixed tooth disk 3, the effect that the cleaner structure that 4 blades 20 form cross shape impeller is simply cleared up is also better, cleaner 19 is then determined, to reach optimum efficiency according to the specification of polymer with the distance of upper fixed tooth disk 3.
Fig. 5 is another schematic diagram improved of the bipolar acceleration polymer swollen particle dissolution device of this band cleaner, this improvement motor 21 will be put and is directly driven power transmission shaft 6, power transmission shaft 6 is connected on liquid storage cylinder 1 by mechanical seal 14, centralizer 15, bearing block 7, motor 21 connection for transmission axle 6, motor 21 is fixed by support.This improvement can save space, simplified apparatus, and convenient installation, also can reduce the corrosion of liquid to power transmission shaft simultaneously.
