Description
Technical field
The present invention relates to pulverize and evenly disperse the media disperser of particulate materials such as various pigment or various ceramic powders, particularly relate to suppress to be used as and pulverize in the container and the media disperser of the centrifugal separating type that the medium of discrete particles shape material medium flows out outside container.
Background technology
The function that media disperser had is to mix the slurries that comprise particulate material in the medium of stirring particles shape and the solvent, through medium particulate material is pulverized and micronize, and this particulate material is dispersed in the solvent.For example, in the ceramic electronic manufacturing process and product, mix the operation that is dispersed in the ceramic glaze slip that has scattered ceramic powders in the solvent with regard to useful ball mill.In this operation, ceramic powders is pulverized and micronize, and organic principles such as bonding agents equably attached on the ceramic powders, ceramic powders is evenly dispersed in the glaze slip.At this moment, in order not allow the mill pearl outside ball mill, flow out, the mill pearl is separated from glaze slip.Therefore, all adopt the ball mill of centrifugal separating type in the past.
As the ball mill of this centrifugal separating type, for example, ball mill mentioned in the patent documentation 1 is arranged.This ball mill possesses mixing part and centrifugation portion, this mixing part possesses with predetermined space and is configured in a plurality of agitating members in the tank diameter of tubular, and be used for stirring the dispersion medium that are filled in the mill pearl in this tank diameter and be injected into slurries shape in the tank diameter by dispersion, the centrifugation from by dispersion of dispersion medium is come out by centrifugation portion on this top, mixing part, and will be fetched into outside the tank diameter by dispersion.In this ball mill, in tank diameter, supply with slurries from the bottom of tank diameter, the mixing part stirring arm of the bottom in tank diameter aqueous by dispersion, in the centrifugation portion on top after disperseing the medium centrifugation, from connect tank diameter above the internal path of rotating shaft discharge slurries.
As same technology, in patent documentation 2, record medium stirring wet-type pulverizer.This medium agitating type pulverizer possesses pulverizing jar that inside is provided with pulverizing chamber, be rotated the main shaft that is installed in the hollow form in this pulverizing jar freely and be installed in whizzer on the part of the above-mentioned pulverizing chamber that is positioned at this main shaft, above-mentioned whizzer is provided with connection in the hollow bulb of above-mentioned main shaft and the separation chamber between the above-mentioned pulverizing chamber, is wholely set the agitating member that is made of a pair of ring and the multi-disc agitator that is connected two interannulars at the peripheral part of above-mentioned whizzer.In this medium stirring wet-type pulverizer, supply with slurries from supply port in abutting connection with the main shaft of pulverizing jar, in pulverizing chamber, after the stirring medium is handled slurries, separate the stirring medium and discharge slurries from the main shaft of hollow form with whizzer.

Patent documentation 2: Te Open 2005-246316
But, under the situation of the ball mill of patent documentation 1 record, because a mill pearl is separated from slurries, in container, flow out so can prevent to grind pearl during operation.Yet because this ball mill is supplied with slurries from the bottom of tank diameter, so the mill pearl is deposited to the bottom of tank diameter because of deadweight when out of service, thereby the mill pearl can be flowed out from the supply port of slurries.
The pump of some type slurries supply usefulness when the running beginning is slack and allow centrifugation portion rotate earlier, and when running stopped, after pump stopped earlier, centrifugation portion stopped again, prevented the outflow of medium thus.If in the medium agitating type pulverizer of patent documentation 2 records, implement such running, because the supply port of slurries is relatively near pulverizing jar, therefore stirring medium can fly upward in pulverizing chamber with the mobile meeting of slurries because of the effect of whizzer, can flow out outside pulverizing chamber from the supply port adverse current of slurries.Like this, in case slurries flow out to the outside in container, medium just is trapped in pipe arrangement or the pump, and the medium in the container just reduces, and has lost the original function that medium has, and just can not get it and pulverizes characteristic or dispersing characteristic.
In recent years, require further micronizes such as the ceramic powders in the slurries are required enhancement of dispersion simultaneously.Therefore, arrive the particle diameter ultra micro granulation of medium less than 100 μ m.Like this, when the medium micronize, the separation of the centrifugal medium that carries out of patent documentation 1,2 records just is difficult to medium is separated fully.Countermeasure as this problem; the slot that only allows slurries to pass through in the leading portion setting of flow export; separate medium; if but with the particle diameter of medium always micronize to less than 100 μ m; slot will be very narrow; passing through of slurries is just slow, and treatment effeciency reduces, and the obstruction of very difficult management slot etc.
Summary of the invention

The specific embodiment
Below, according to Fig. 1～embodiment explanation the present invention shown in Figure 3.
Shown in the sectional drawing of Fig. 1, the media disperser 10 of present embodiment possesses oblate shapes of containers 11 and is housed in rotor 12 in this container 11 rotationally, is formed with the gap between the surface of the inner face of container 11 and rotor 12.In this container 11, filling the medium M of ormal weight; therefore; rotor just rotates the slurries that mix medium M in the gap between the outer peripheral face of the inner face of container 11 and rotor 12 and comprise particulate material in container 11; and in slurries, particulate material is pulverized and micronize, simultaneously microparticle is dispersed in the slurries.At this moment, can use average grain diameter for example less than the particle of 100 μ m as medium M.
As shown in Figure 1, through hole 11A is formed on the central part of the upper surface of container 11, and first throughput 13 is rotated through seal 14 and is installed in freely on the through hole 11A.First throughput, 13 openings are at the upper surface central part of container 11, and extend to vertical top.Be formed on the central part of rotor 12 corresponding to the through hole 12A of through hole 11A, second throughput 15 that constitutes the slurries outflow pathway is installed on this through hole 12A.Second throughput 15 is extended to vertical top along first throughput 13 from the through hole 11A of the lower surface perforation container 11 of rotor 12.In other words, first throughput 13 forms the diameter bigger than second throughput 15, with second throughput, 15 a total core.In the present embodiment, first, second throughput 13,15 links mutually and rotates integratedly with respect to container 11.Gapped between the outer peripheral face of the inner peripheral surface of first throughput 13 and second throughput 15, this gap forms the inflow path of slurries.
Shown in the overall diagram of the media disperser of major part being cut open expression of Fig. 2, dispose in the side of container 11 and to make rotor 12 motor rotating 16.That is, belt pulley 16A is installed in the rotating shaft of motor 16, and on first throughput 13 of container 11 sides belt pulley 13A is installed.Dish is hung endless belt 17 on these belt pulleys 13A, 16A, and the rotation of motor 16 makes first, second throughput 13,15 rotate integratedly with respect to container 11, just rotation in container 11 of rotor 12.
Shown in the plane of seeing from the below of Fig. 1 and Fig. 3, lower surface at rotor 12, be fixed with for example agitator 18 of 3 elongated shapes, uniformly-spaced separate and be radial along circumference, the medium M that 18 pairs of these agitators invade the lower surface of rotor 12 gives centrifugal force, and medium M is just reverse mobile slurry stream to the inner peripheral surface side from the central portion of container 11.Here, agitator 18 forms the dull and stereotyped wing, still can adopt other shapes such as cambered aerofoil as required aptly, also can increase and decrease the radical of agitator as required aptly.Also can change the length of agitator 18 aptly.And, only illustrate a part of medium M on Fig. 3, and in fact medium M spreads all over gap week entirely between the outer peripheral face of the inner peripheral surface that is dispersed in container 11 and rotor 12.
Next, action is described.At first, in advance the medium M of ormal weight is filled in the container 11; Under this state, make rotor 12 rotations through motor 16, the slurries that comprise particulate material are supplied with in the gap from first, second throughput 13,15 shown in the arrow among Fig. 1, Fig. 2 immediately, with slurries container 11 are full of.Like this, because the rotation of rotor 12 is just given the medium M of the bottom that is present in container 11 centrifugal force from agitator 18, as Fig. 1, shown in Figure 3, medium M just is integrated in the gap between the outer peripheral face of the inner peripheral surface of container 11 and rotor 12.Under this state, in case supply slurries, the medium M that is integrated into the inner peripheral surface side of container 11 just has the trend that moves to second throughput 15 from the bottom of container 11 with flowing of slurries, but, from the agitator 18 of the rotor 12 that rotates accept centrifugal force and slurry stream reverse central portion from container 11 move to inner peripheral surface, not to second throughput, 15 side shiftings, and do not flow out to the outside from second throughput 15.
In the gap between the outer peripheral face of the inner peripheral surface of container 11 and rotor 12; slurries and medium M accept revolving force and mixed stirring from rotor 12; by the effect of medium M the particulate material in the slurries is pulverized and micronize, simultaneously by micronize particulate material be evenly dispersed in the slurries.During this period; owing to supply with slurries continuously; so the slurries of the particulate material that has comprised by micronize flow in the container 11 along the arrow directions X, and converge in central part along the bottom surface of container 11, flow into second throughput 15 and outside container 11, discharge along arrow Y direction.
Even medium M also will move from the inner peripheral surface side direction central portion of container 11 along with flowing of slurries, but as the above can from agitator 18 accept centrifugal force and from slurries centrifugation come out, turn back to the inner peripheral surface side of container 11.On the other hand, by micronize particulate material also accept the centrifugal force of agitator 18 because its particle diameter is far smaller than medium M for a short time, only accept a little centrifugal force, so can't break through slurry stream, and discharge to the outside from second throughput 15.
After slurries are handled, make still rotation temporarily of motor 16 even as prior art, stop after the supply of slurries for the outflow that prevents medium M, medium M also under the effect of agitator 18 to the set of the inner peripheral surface side of container 11, can be along second throughput, 15 adverse currents to the outside.
As discussed above; according to present embodiment; supply with slurries from first throughput 13 and the gap between second throughput 15 of the central portion that is in container 11; effect by rotor 12 in container 11 mixes slurries and medium M; make the particulate material micronize in the slurries thus, the particulate material that simultaneously can make by micronize is evenly dispersed in the slurries.These slurries by container 11 the bottom surface and the gap between the lower surface of rotor 12 much larger than contained particle grain size, discharge to the outside via second throughput 15 from the central part of rotor 12, so, the treatment effeciency of slurries is reduced, can discharge from second throughput 15 effectively.After the supply that stops slurries, though rotor 12 rotation, medium M also from slurries centrifugation come out and, do not flow out to the outside from second throughput 15 positively to the inner peripheral surface side set of container 11.
According to present embodiment,,, can come out medium M centrifugation from slurries more effectively so agitator 18 is given medium M with centrifugal force owing to agitator 18 is set at the lower surface of rotor 12.Because first throughput 13 and second throughput, 15 a total core and diameter are greater than second throughput 15, so the gateway of slurries can be concentrated on compactly the central portion of container 11.Because first throughput 13 and the rotation of second throughput, 15 one are rotated freely relative to container 11, and are attached on the motor 16, so can simplify the rotating mechanism of rotor 12.
The present invention is not limited to above-mentioned embodiment, for example in the above-described embodiment the inflow path of the gap between first throughput 13 and second throughput 15 as slurries, and the outflow pathway of second throughput 15 as slurries, but also can be in contrast.Except that belt pulley, the rotary drive mechanism of rotor also can be with formations such as gear mechanisms.The operating condition of media disperser of the present invention etc. can suitably be set as required.Key is that medium M does not flow out just passable as long as the outflow inflow portion of slurries is in the central part of container.
The present invention can be widely used for pulverizing and evenly disperseing the media disperser of the particulate material of various pigment or various ceramic powders etc.
