Von Fl ü ssigkeiten) "; ISBN3-8169-2309-7; disclose the different form of implementation that is used for rotating disk in the 74th page, this rotating disk for example is designed to smooth disk, the cup that opens wide downwards, is designed to holes or ribbing disk or is designed to the hollow cylinder of porous.In any case adding liquid always realizes by one or more pipeline.In addition, disclose a kind of device of the material web for wetting movement in DE 4227136A1, wherein fluid discharge realizes by means of flusher, and row's rotating disk is set in this flusher.Disclose a kind of liquid sprayer in DE 10053305A1, wherein liquid thereby helps the center that pipeline is transported to rotating disk, and its turntable has the driving shaft of downward protrusion.
Regulate the amount of institute's spraying liquid as follows, namely by means of pipeline liquid more or less is transported to rotating disk.Yet confirm that there is following shortcoming in it, determine in each unit interval under the situation of amount of liquid, no longer from pipeline constantly but emit liquid with the form of dropping liquid.And causing spraying liquid very by spells with the interpolation of dropping liquid form, this causes the wetting very unevenly workpiece of spraying liquid, for example paper web face or fabric web.
Another problem is, the pipeline with very little internal diameter is owing to the deposition of the impurity of carrying with liquid or liquid additive is easy to block, thereby no longer carries liquid.Therefore, this pipeline must have the dimensions by tool, thereby goes out the minute impurities in the liquid.
Summary of the invention
Therefore, the object of the present invention is to provide a kind of centrifugal atomizer, utilize this centrifugal atomizer can discharge very small amount of liquid.
According to the present invention, this purpose realizes by the centrifugal atomizer that is used for liquid, this centrifugal atomizer has the dish of rotation, the drive unit that is used for this dish, and for the conveying device that liquid is transported on this dish, wherein this dish has the distribution surface for liquid, and at least one perforation is set in this distribution surface, by described perforation the shunting of liquid is assigned to another plane from main flow, wherein this dish has the first second sprinkling edge that sprays the edge and be used for the shunting of spraying liquid for the workflow of spraying liquid, a plurality of described perforation are set, described perforation is evenly distributed on the circumference between rotating shaft and the described sprinkling edge, between described perforation, web is set, constituting towards the web face of the main flow form with the inclined-plane of described web, between described perforation, web wall is set, web wall makes described web flange, in direction of rotation, described web wall is arranged on after the web, and wherein in described distribution surface, the zone from inner radial to radially outer of described perforation, be provided with height tolerance, and the position specific diameter in inner radial zone is darker to the position of perimeter.
Equally also have the dish of rotation according to centrifugal atomizer of the present invention, for example the liquid that will spray by means of pipeline is introduced or is transported in this dish.Yet in the dish of rotation, all the liquid that spray no longer spray by spraying the edge, but are that main flow is divided into shunting and workflow with the liquid that sprays.This distribution realizes by one or more perforation that are arranged in the distribution surface.Shunting arrives another by this way and namely second sprays the edge and be discharged from there.The remaining workflow that is used for wetting workpiece is sprayed the edge sprinkling by first.Because main flow is divided into shunting and workflow, reduced the amount that is actually used in wetting workpiece of liquid, for example needn't reduce the amount of the liquid of carrying by pipeline at this.So just guaranteed to stop reliably dropping liquid to form, had the pipeline of bigger flow cross section but also guaranteed to use, thereby needn't worry to block, and be not that the liquid of all carrying is that whole main flows is sprayed onto on the workpiece.Tell shunting by one or more perforation from main flow, this shunting is discharged from by the second sprinkling edge then, and wherein this shunting can be told or discharge and be transferred in the water tank by another device by means of the orifice plate that is fit to.
Propose in a preferred improvement project, the first sprinkling edge is positioned on the second sprinkling edge and/or two sprinkling edges have identical radius.The sprinkling dish has the shape of flat diabolo or the shape of flat hourglass basically.Because two are sprayed the edge and have different height, can tell and for example be transported in the water tank by means of orifice plate relatively simply so spray the shunting of spraying at the edge by the bottom.Because two are sprayed the edge and have the radial spacing identical with respect to rotating shaft, so for the shunting that spray workflow and the bottom of top sprinkling, have substantially the same spraying condition and sprinkling ratio.In addition, one or more perforation can arrange diametrically opposed outside far away.
Be advantageously provided a plurality of perforation, and described perforation is evenly distributed in rotating shaft and sprays on the circumference between the edge in addition.Described perforation forms porous disc to a certain extent, and this porous disc is passed in shunting.Regulate the amount of shunting by layout, shape, size and the position of described perforation.
In an improvement project, propose, in distribution surface, the zone from inner radial to radially outer of perforation, be provided with height tolerance.At this advantageously, inner radial zone specific diameter is dark to the perimeter.Workflow must flow in the higher zone of radially outer from the darker zone of inner radial like this.For liquid, be big relatively obstacle because have the transitional region of perforation, so can utilize the perforation with relatively little open cross-section and/or utilize few relatively perforation to produce bigger shunting and corresponding less workflow.
According to the present invention in one embodiment, between perforation web is set, it constitutes towards the web face of the main flow form with the inclined-plane.This web can be smooth and/or hollowly or convex ground crooked.By this way, can control the amount of shunting or the amount of workflow extraly.Web can inner radial broaden or be tapered to radially outer gradually in addition.
One according to embodiments of the invention in, advantageously Chuan Kong cross section is adjustable.By this way, can accurately regulate the amount of shunting or will be sprayed onto the amount of the workflow on the workpiece.The adjusting of the cross section of perforation for example can be by moving orifice, by insert or suchlike the adjusting.
Embodiment proposes, and distribution surface and another plane are basically each other and/or with respect to a horizontal cross-section mirror image symmetry.Particularly, be positioned under the distribution surface another plane perpendicular to rotating shaft and for example can zero deflection ground arrange.The effective coverage on this plane is in outside the perforation diametrically, in other words, sprays between the edge in perforation and second.
For liquid can be transported to dish in the heart, drive unit is under the dish, its advantage is in addition, drive unit can be by liquid wets.In addition because distribution surface can freely touch, so can carry out cleaning very simply.
In one embodiment, the size of drive unit is so definite, makes the second sprinkling edge be in outside the drive unit diametrically.In the time of in liquid is in greater than the circumferential area of drive unit, liquid just sprays from dish.
