Further, the ratio between the long axis of the cavity and minor axis length are 2:1.
Further, the ratio between exit radius of the short axle of the cavity and feed pipe is 4.3:1.
Further, the dowel is set as three and is that round steel is made, the long axis length of the shunting body, semiaxis
The ratio between the diameter length 4 of minor axis length, round steel:1:0.2.
Further, the length of the ejection section in axial direction is that the semi-major axis of the cavity is long.
Further, the spacing at the center of the shunting body and the center of the cavity is the short axle of 1.5 times of cavitys
It is long.
The beneficial effects of the utility model：The utility model realizes the uniform and stable spray of sand ball using tertiary structure
It penetrates, improves projected area as possible, ensures to spray uniform and stable property.Level-one, when sand ball is transported to by very long pressure piping
When feed pipe, due to the structure feature of the circular shape of feed pipe, bore gradual change make sand ball by gradually discharge, dissipate (because
Bore gradually becomes larger, pressure reduces), two level further releases stress in cavity after the cavity for entering elliposoidal, and makes
Obtain concentrated bundles of fluid to be disperseed originally, the secondary mixing of part sand ball, three-level, when finally passing through ejection section, due to ejection section
In horn-like (coniform), all sand balls are buffered after release at the portlet of ejection section in cavity since bore becomes again
Small, pressure starts to be promoted, since space moment amplifies when the sand ball of accumulation is sprayed across portlet towards large port, sand ball stream
The pressure of body discharges suddenly again so that sand ball can be sprayed away with larger area, and due to portlet center
Sand ball density is larger, therefore is provided with special shunting body so that the sand ball of center is blocked, disperses around, relatively
In it is existing make sand ball from conveyance conduit to blast nozzle directly at a high speed project for, sand ball is not only projected with larger area, is also sprayed
Penetrate to be more uniformly distributed stabilization, reach more uniform piece surface treatment effect, be particularly suitable for hardness it is slightly lower, surface treatment want
Seek the blasting craft of higher parts.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Specific implementation mode
Illustrate that the embodiment of the utility model, those skilled in the art can be by these by particular specific embodiment below
Content disclosed by specification understands other advantages and effect of the utility model easily.
The utility model is described in further detail with reference to the accompanying drawings and examples：
As shown in Figure 1, a kind of blast nozzle, including feed pipe 1, appearance sand warehouse 2, ejection section 3, there are one the tools of appearance sand warehouse 2
The cavity 4 of ellipsoid and wherein one end of the long axis of cavity 4 are provided with import, and the feed pipe 1 is one section of circular arc pipeline section, feed pipe
1 outlet connects with the import of appearance 2 cavity of sand warehouse, and the circular arc protrusion direction of the feed pipe 1 and 4 long axis direction of cavity is convex
Origin or beginning protrusion direction is consistent, and outlet is additionally provided in the other end of the long axis of the cavity 4.The ejection section 3 is in horn-like, injection
The small end in portion 3 connects with the outlet end of cavity 4, and the axis of ejection section 3 is coaxially disposed with the long axis of cavity 4, in the ejection section 3
Horn mouth in be equipped with the shunting body 5 of the long axis ellipsoid coaxial with the long axis of cavity 4, the shunting body 5 is fixed on injection
Several dowels 6 support of 3 inner wall of portion is fixed, and one end of dowel 6 is fixed on the inner wall of ejection section 3, and the other end is fixed
On 5 surface of shunting body, all dowels 6 rounded array centered on the axis of ejection section 3.
Further, the feed pipe 1 along its import a to outlet b direction bore become larger, and its inlet radius with
The ratio between exit radius is 1:3.5.The bore ratio is conducive to the gradually release of sand ball, to prepare before injection.
Further, the ratio between the radius R of the axis of the feed pipe 1 and the inlet radius of feed pipe 1 are 10:1, the radius
The gradually release that sand ball can further be optimized, for the effect prepared before injection.
Further, the ratio between the long axis of the cavity 4 and minor axis length are 2:1, the cavity of this kind of shape is conducive to sand ball
It converges and re-mixes in the cavity, to be buffered after release, put aside energy, promote jeting effect.
