Description
Invention field
The present invention relates to a kind of dispersal device to material enforcement dispersing technology process, this material for example is a kind of raw material of graining paste, and wherein the pigment powder is dispersed in varnish or the solvent with high concentration; The present invention be more particularly directed to a kind of dispersal device, in this device, the distance that dispersed material moves in container has been lengthened out, thereby material can be disperseed fully.
Background technology
For example, printing-ink or coating material are to make with graining paste, and in this graining paste, pigment powder is dispersed in varnish or the solvent with high concentration.In the dispersion process of pigment powder in solvent or similar mediums, the pigment powder is assembled and the regenerated granule of formation, is preferably all pulverized, and it is dispersed in the solvent, to form fine granules of pigments, wherein there is not big particle, so that improve the colorability of printing-ink or coating material.
Up to now, known dispersal device has sand grains grinding mill, abrasive particle grinding mill, ball mill, grater and similar device.In above-mentioned dispersal device, a kind of device that carries out the dispersing technology process continuously is configured to as shown in Figure 7.
That is to say that this device is a horizontal structure, have the cylinder 101 of a horizontal arrangement, in tube 101, rotating shaft 103 levels are installed, and can rotate.There is one group of rod stirrer paddle 105 to extend radially in the rotating shaft 103, and mutually disposes vertically with at random spacing.In tube 101, spheric granules medium 107 is made by steel, pottery or building stones, and all encapsulation is wherein so that implement the technical process of dispersion.
Use said structure, when rotating shaft 103 usefulness motors or other similar devices driven rotary, the graining paste raw material is packed into through the charging aperture 109 that is positioned at tube 101 1 ends, and granule medium 107 is loaded on stirrer paddle stirring in the rotating shaft 103.So, the dispersing technology process of graining paste raw material is implemented.Standing the graining paste of dispersing technology process discharges from the discharging opening 111 that is positioned at tube 101 other ends continuously.
Said structure faces a kind of what is called " short circuit " (short pass) problem sometimes, at this moment, fails evenly to disperse through the graining paste raw material that charging aperture 109 enters in the tube 101, and the graining paste that includes thick granules of pigments is discharged from discharging opening 111.This just the problem that a dispersing technology process fails to implement satisfactorily occurs.
Observe the athletic meeting of granule medium 107 and find that the stirrer paddle that granule medium tends to follow in the rotating shaft 103 together rotates, the problem that the dispersing technology process can not effectively be implemented therefore occurs.
Filling rate as tube 101 that granule medium 107 is packed into improves to prevent " short circuit ", and " short circuit " problem is avoided to a certain extent.If but the filling rate of granule medium 107 too improves, just clogging can take place, at this moment the granule medium 107 in the tube 101 can be prejudicially to discharging opening 111 motions.So another problem has just taken place, technological operation at this moment can not be implemented safely.Therefore, 75%～80% of the general taking technique operating time of the filling rate of granule medium.
A kind of structure commonly used as shown in Figure 8, this device is for vertical structure, wherein tube 101 is an arranged perpendicular.The rotating shaft 103 that stirrer paddle 105 is housed is vertical installations, can rotate.
Said structure is horizontal structure is converted to vertical stratification and constitutes, and wherein, the charging aperture 109 of graining paste raw material through being positioned at tube 101 tops enters tube 101.In addition, granule medium 107 is stirred in rotating shaft 103 rotations, thereby realizes the dispersing technology process to the graining paste raw material.Graining paste through the dispersing technology process is discharged from the discharging opening 111 that is positioned at tube 101 bottoms.Discharging opening 111 has a granule medium separating mechanism 113, and the pattern of this separating mechanism for example can be grid type or net form, is used to prevent granule medium 107 discharges; Discharging opening 111 also has a raw material blow-off valve 115, can open/close discharging opening 111.
Because said structure only is simply tube 101 to be converted to vertical structure by horizontal type structure, so, exist the similar problem that is suffered with horizontal type structure equally.
Another kind of common structure such as Fig. 9 and shown in Figure 10.Generally say with schematic diagram, the layout of described structure is such: the first and second rotating shaft 117A and 117B vertically are installed in the cylindrical tube 101 of arranged perpendicular, plate shape first and second stirrer paddle 119A and the 119B, arrange by having 90 ° of phase differences each other, be contained on the first and second rotating shaft 117A and the 117B, to avoid the first and second stirrer paddle 119A and 119B interference.
Use said structure, the part of the rotational trajectory of the first and second stirrer paddle 119A and 119B is overlapping.Yet because the first and second stirrer paddle 119A and 119B are board-like shape, the part in the tube 101 in the graining paste raw material can be relayed to together at tube.In addition, those parts in contiguous 121A and 121B zone are outside the first and second stirrer paddle 119A and 119B rotary area.So, just producing a problem, that is exactly in the dispersing technology process, and the graining paste raw material is finished dispersion unsatisfactorily, causes uneven consequence equally.
