Abstract
A kind of flat blast nozzle device, the outer end of nozzle are wrapped up by protective shell.Nozzle interior is divided into contraction section, accelerating sections and three sections of diffuser.Wherein contraction section entrance is round, and exit shape is approximately one elongated rectangular, and contraction section is then that the two sides inclination shaped like eight words gradually tapers up shape；Accelerating sections shape is approximately elongated hexahedron；Diffuser is also designed to the inclination of the two sides shaped like eight words gradually diffusion shape.For sand material after nozzle ejection, the sand material of diverging, which is sprayed on workpiece, will form one along the equally distributed rectangular shape of a certain axis in this way.Using flat blast nozzle to make sand material uniformly dissipate along a certain axis, sandblasting operating efficiency is improved.
Description
Technical field
The utility model relates to a kind of flat blast nozzle devices, equal along a certain axis after sand material sprays more particularly to realize
The nozzle of even diverging.
Background technique
Currently, well known blast nozzle has straight barrel nozzle, venturi shape nozzle and a square hole nozzle, either it is above-mentioned which kind of
Nozzle, for the sand material that nozzle ejects more or less all there is non-uniform phenomenon is dissipated, i.e. sand material mostly concentrates on nozzle
On the line position of axle center.This diverging will cause the cleaning of some region transfers, and occur the insufficient phenomenon of cleaning except the region.
No matter this is to workpiece surface abrasive jet cleaning efficiency, or can all generate certain influence to workpiece surface invigoration effect, especially right
Metal sheet can generate unintended deformations.
Summary of the invention
In order to overcome the shortcomings of the prior art described above, the utility model provides a kind of relatively uniform diverging of sand material
Flat blast nozzle.
The technical scheme adopted by the utility model is nozzle is divided into contraction section, accelerating sections and three sections of diffuser.Wherein
Contraction section entrance is circle, and outlet is one approximate elongated rectangular, and entrance and outlet transition section are the two sides shaped like eight words
Inclination gradually tapers up shape.Accelerating sections shape is approximately elongated hexahedron.Diffuser is also designed to the two sides shaped like eight words
Tilt gradually diffusion shape.For sand material in this way under the impetus of air-flow, the sand material meeting approximation of ejection diverges to a rectangle
Shape.The sand material of striking work concentrates on a certain axis, rather than concentrates on the region of certain point.Along perpendicular to this axis
Spray gun is moved in direction, and spray gun scans the region cleared up and also just forms the relatively uniform long band of cleaning.
The aperture communicated with the outside world is enclosed in nozzle diffuser radial distribution one, this is because the air-flow of high speed enters nozzle
It will form negative pressure after diffuser, the effect of aperture is namely to nozzle diffuser make-up gas.
Compared with prior art, the utility model has the beneficial effects that sand material can uniformly be dissipated along a certain axis, improve spray
Sand clears up non-uniform phenomenon, improves sandblasting operating efficiency.

Specific embodiment
In Fig. 1 and in Fig. 2, the internal structure inside nozzle 4 is: nozzle is divided into contraction section, accelerating sections and diffuser
Three sections.Wherein contraction section entrance is round, and outlet is one approximate elongated rectangular, and entrance and outlet transition section are shaped like eight
The two sides inclination of word gradually tapers up shape；Accelerating sections is approximately elongated hexahedron, and contraction section smoothly transits with accelerating sections circular arc；
Diffuser is also designed to the inclination of the two sides shaped like eight words gradually diffusion shape, and it is sliding that same accelerating sections and diffuser are also round arc light
Transition.4 outer shape of nozzle is cylindrical body.
In Fig. 1 and in Fig. 2,1 one end outer profile of connector is indention shape, thus after making connector 1 be inserted into sand blast hose
It is not easy loose or dislocation, the other end of connector 1 is screw thread, to connect with mounting shell 3.
In Fig. 1 and in Fig. 2,3 interior shape of mounting shell is that cylinder is hollow, external there are four platform, is provided with spiral shell on platform
Pit, effect are easy for fixed button mounting plate 7；3 two sides of mounting shell are provided with screw thread, so as to respectively with connector 1 and tonifying Qi shell 5
Connection.
It is circular hole inside tonifying Qi shell 5 in Fig. 1 and in Fig. 2, tail end has step, to limit to nozzle 4；Tonifying Qi shell 5
Front end is screw thread, in order to the connection of mounting shell 3.
In Fig. 1 and in Fig. 2, connection relationship are as follows: connector 1, mounting shell 3, tonifying Qi shell 5 are together by a threaded connection,
Nozzle 4 is wrapped in the inside, to prevent the nozzle of excessive high hardness to be crushed because of collision；Equipped with sealing between connector 1 and nozzle 4
Pad 2 is played in junction sealing function；Button installing plate 7 is connected on mounting shell 3 by screw 6, and switch button 8 is mounted in and presses
On button mounting plate 7, it is worker's start and stop sandblasting at any time operation for convenience that switch button 8, which is arranged on spray nozzle device,.
The process that sand stream crosses spray nozzle device is: after worker starts switch button 8, sand material enters spray inside connector 1
Eight word contraction sections of mouth 4, then pass through the accelerating sections of approximate hexahedron shape, finally spray by eight word diffusers, ejection
Sand material will uniformly be dissipated along a certain axis.
