Detailed description of the invention
As it is shown in figure 1, left end is the port of export of nozzle body, right-hand member is the entrance of nozzle body
End, and definition nozzle body is nozzle body outlet section near a section of the port of export, nozzle body
One section of close arrival end is nozzle body entrance, and in like manner, top board 1 is near the one of the port of export
Section is top board outlet section, and top board 1 is top board entrance 11 near a section of arrival end, base plate 3
Being base plate outlet section near a section of the port of export, base plate 3 enters for base plate near a section of arrival end
Mouth section 31.
Referring to the drawings, a kind of window shape ease gas formula broadband powder-feeding nozzle, including nozzle body, described
Nozzle body includes folding top board 1, dividing plate 2 and the base plate setting and interfixing the most successively
3, top board 1 entrance is inclined upwardly extension, and base plate 3 entrance matches with top board entrance
Close, i.e. base plate entrance 31 closely fits with the contact surface of top board entrance 11, plays close
Envelope effect, top board entrance 11 tilts to be provided with powder through hole 111, to increase powder through hole
111 discharge areas, described powder through hole 111 exposes to one end of top board and constitutes powdering inlet 12；
Groove 21, top board 1 and base plate 3 and middle described groove is had on described dividing plate 2
21 enclose powder flow channel, and one end of described powder flow channel connects with powder through hole 111, separately
One end extends to the nozzle body port of export and constitutes dust outlet 13；
Ease transom window mouth 5 is all offered on described top board 1 outlet section and base plate 3 outlet section, middle
Powder flow channel by the ease transom window mouth 5 of both sides and ft connection, and ease transom window mouth 5 is with described
Drainage screen 4 it is provided with between powder flow channel.Ease transom window mouth 5, near dust outlet 13, is reducing powder
While end outlet 13 load volumes, still can keep the output speed of powder at dust outlet 13
Degree so that powder can keep good deflection, enters molten bath more accurately,
Further, the bottom surface of top board 1 and the end face of base plate 3 are provided with the locating surface 7 of depression,
The centre of locating surface 7 offers described ease transom window mouth 5, locating surface 7 is equipped with and is completely covered
The drainage screen 4 of ease transom window mouth 5, described drainage screen 4 is fixed on locating surface 7, drainage screen 4
Size and shape all identical with locating surface 7, and the thickness of drainage screen 4 and locating surface 7 is recessed
Fall into the degree of depth identical, so that the surface of the drainage screen 4 on top board 1 keeps concordant with top board, base plate
Drainage screen 4 surface on 3 keeps concordant with base plate 3, and locating surface 7 is filled and led up by drainage screen 4,
The bottom surface of top board 1 and the end face of base plate 3 keep smooth, can fit completely, it is ensured that top board 1,

The action principle of the present invention is:
Powder enters powder through hole 111 from powdering inlet 12 under the sweeping along of carrier gas, through powder
Through hole 111 enters powder flow channel, and powder, by the acceleration of carrier gas, has certain kinetic energy,
When through excessive transom window mouth 5 region, powder particle under effect of inertia still along powder flow channel to
Front motion, and a large amount of carrier gas can be scattered and disappeared from the ease transom window mouth 5 of both sides in effusion, the part of powder bundle
Granule has the trend outwards dissipated with carrier gas, but can be stopped by wire netting.
At dust outlet 13, load volume significantly reduces, and turbulent flow reduces therewith, and powder thus dissipates
Improved.
The present invention while load volume, still can keep powder at minimizing dust outlet 13
Export the output speed of powder at 13 so that powder can keep good deflection, enters more accurately
Entering molten bath, powder using efficiency is high.This invention efficiently solves powder course of conveying needs load volume
Big and powder output needs the contradiction that load volume is little, to improving powder using efficiency and cladding quality
There is certain effect.
