Description
Technical field
The present invention relates to dispersion machine field, particularly relate to a kind of rotary-type dispersion machine.
Background technology
Need in the production process of coating pigment solids particle is carried out fragmentation by external force and is dispersed in resin solution or emulsion, make it the suspended dispersion of a formation fine uniform structure.Pre-dispersed is the first operation of coating material production, by pre-dispersed, pigment is mixed, and the air simultaneously making mill base replace part surface of pigments to adsorb, makes pigment obtain fractional wettability, usually use dispersion machine time pre-dispersed.
The critical component serrated disks formula impeller of dispersion machine of the prior art, it is driven by the shaft rotated, and the rotation of impeller makes mill base produce turbulent area, in turbulent area, the particle of pigment and mill base are subject to stronger shearing and percussion, thus are distributed in mill base by pigment.The key of dispersion is between pigment and mill base, formed between the mixture of pigment mill base and shear and percussion, in dispersion process, pigment, mill base are driven by impeller and rotate to same direction passively, are unfavorable for making formed relative motion between dispersion thus produce more effective shearing and percussion.
Summary of the invention
The invention is intended to provide a kind of rotary-type dispersion machine, allow pigment and mill base form jet, the material in jet flow and dispersion tube produces to be sheared and percussion, thus improves dispersion machine effect.
Rotary-type dispersion machine in this programme, comprise fuselage, cantilever, dispersion tube and vane pump, cantilever vertical is in fuselage and be fixed on fuselage, dispersion tube is fixed on fuselage, dispersion tube open top, bottom lock, cantilever is positioned at directly over dispersion tube, cantilever is fixed with runner shaft, runner shaft inside is provided with carrier pipe, carrier pipe top is communicated with blade delivery side of pump, runner shaft bottom-hinged has runner, cavity is provided with in runner, cavity sidewalls is evenly equipped with some spray-holes along clockwise direction, spray-hole is through hole, the bottom of dispersion tube has material sucking port, material sucking port is communicated with the entrance of vane pump, the bottom of carrier pipe and cavity connects.
The know-why of this programme and beneficial effect are: be added in dispersion tube by pigment and mill base, start vane pump, the mixture of pigment and mill base is pumped in carrier pipe, utilize the pressure of vane pump pumping, by mixture from the cavity in carrier pipe press-in runner, mixture is stressed after entering cavity and sprays from spray-hole, form jet, runner turns clockwise by the reaction force of jet, the mixture rotarily driven in dispersion tube of runner rotates, the direction of now mixture rotary motion is contrary with the direction of jet, thus mixture is collided and produces shearing and percussion, thus realize dispersion, pumping and sustainablely to disperse repeatedly.Compared with prior art, the mixture driven by impeller can only rotate to same direction passively, and it is contrary with the direction of the jet that runner sprays by the direction of the mixture rotary motion of driven by rotating wheel, more easily relative motion is formed between mixture, mixture is more easily collided and produces shearing and percussion, dispersion effect is better.
Pigment in prior art and mill base are rotated the eddy current of formation by this programme in dispersion tube, have become the jet flow of spraying, and the material in jet flow and dispersion tube produces to be sheared and impact, and is more conducive to the dispersion of pigment and mill base, thus improves the dispersion effect of dispersion machine.
As the preferred version one of above-mentioned such scheme, described cavity floor is provided with spray-hole, and during pumping, mixture sprays from below, strengthens spray volume, increases the frequency of a pump period shearing and percussion.
As the preferred version two of such scheme, the diameter of described spray-hole is 5-10mm, and diameter is too little easily causes correlation hole plug, and diameter makes too greatly the speed of jet too little, reduces the effect of shearing and percussion.
As the preferred version three of such scheme, the bottom surface of described runner shaft and described cavity floor contacted inner surfaces, prevent runner from the process of rotating, play occurring and damaging cavity.
As the preferred version four of such scheme, the diameter of described carrier pipe is greater than 20mm, ensures in the process of dispersion, has enough pump outputs to drive runner to rotate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the rotary-type dispersion machine of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: fuselage 1, cantilever 2, dispersion tube 3, vane pump 4, runner shaft 5, carrier pipe 6, spray-hole 7, runner 8, cavity sidewalls 801, cavity floor 802.
The rotary-type dispersion machine of embodiment is substantially as shown in Figure 1: comprise fuselage 1, cantilever 2, dispersion tube 3 and vane pump 4, cantilever 2 is also fixed on the fuselage 1 perpendicular to fuselage 1, dispersion tube 3 is fixing on the fuselage 1, dispersion tube 3 open top, bottom lock, cantilever 2 is positioned at directly over dispersion tube 3, cantilever 2 is fixed with runner shaft 5, runner shaft 5 inside is provided with carrier pipe 6, carrier pipe 6 top is communicated with the outlet of vane pump 4, runner shaft 5 bottom-hinged has runner 8, cavity is provided with in runner 8, cavity sidewalls 801 is evenly equipped with along clockwise direction four spray-holes 7, cavity floor 802 is provided with four spray-holes 7, the axial line of spray-hole 7 is parallel with runner 8 diameter line, the bottom surface of runner shaft 5 and cavity floor 802 contacted inner surfaces, the bottom of dispersion tube 3 has material sucking port, material sucking port is communicated with the entrance of vane pump 4, the bottom of carrier pipe 6 and cavity connects.
In specific implementation process, pigment and mill base are added in dispersion tube 3, start vane pump 4, the mixture of pigment and mill base is pumped in carrier pipe 6, utilize the pressure of vane pump 4 pumping, mixture is pressed into the cavity in runner 8 from carrier pipe 6, mixture be stressed after entering cavity from spray-hole 7 spray, form jet, runner 8 turns clockwise by the reaction force of jet, the mixture rotarily driven in dispersion tube 3 of runner 8 rotates, the direction of now mixture rotary motion is contrary with the direction of jet, thus mixture is collided and produces shearing and percussion, thus realize dispersion, pumping and sustainablely to disperse repeatedly.
