Abstract
The utility model discloses a nozzle for powder spraying, which comprises a connecting pipe and a diffusion pipe, wherein one end of the connecting pipe is communicated with a spray gun for providing powder fluid, and the other end of the connecting pipe is communicated with the diffusion pipe; the diffusion tube stretches into the connecting pipe and the junction between the two is equipped with the dispersion seam, the spiral fan has been erect in the connecting pipe, the spiral fan is established the upper reaches of diffusion tube entry. The utility model discloses discrete powder that both can be even at the spraying in-process can improve the blowout powder directive property again to improve the utilization ratio of powder. The effect of uniform spraying is realized through spraying at two positions of the dispersing seam and the outlet of the diffusion tube; diffusion tube one end stretches into in the connecting tube, has and carries out directive discrete effect to the powder fluid, has improved the blowout powder directive property, and the utilization ratio of powder improves.
Description
Technical field
This utility model relates to nozzle technology field, especially a kind of powder spray nozzle.
Background technology
Powder spray is a kind of widely used spraying technology, its work process is: powder sprays in electrostatic field by nozzle is uniformly discrete, by the effect of electrostatic field by powder adsorption at surface of the work, the powder then adsorbed is through high-temperature baking, solidification, and ultimately forms coating.
Traditional nozzle only has primary structure, and by the compulsory purpose being separated by powdery fluids and reaching uniform discrete powder, although so can reach uniform effect, but the directivity of ejection powder is greatly lowered, and the utilization rate of powder is low.
Utility model content
This utility model is for the deficiencies in the prior art, it is proposed to a kind of powder spray nozzle, sprays uniformly, and directivity is good.
In order to realize above-mentioned utility model purpose, this utility model provides techniques below scheme: a kind of powder spray nozzle, and including connecting tube and anemostat, described connecting tube one end connects with the spray gun providing powdery fluids, and the other end connects with described anemostat; Described anemostat stretch into described connecting tube and between the two junction be provided with dispersion seam, described connecting tube internal frame is provided with screw fan, and described screw fan is located at the upstream of described anemostat entrance.
Preferably, described anemostat stretches into the length of described connecting tube is 10mm.
Preferably, the cross section of described connecting tube is circular or square.
Compared with prior art, this utility model have the advantage that in spraying process both can discrete powder uniformly, ejection powder directivity can be improved again, to improve the utilization rate of powder. By disperseing seam and anemostat to export the spraying of two places, it is achieved the effect of even application; Anemostat one end is stretched in connecting tube, has the discrete effect that powdery fluids carries out directivity, improves ejection powder directivity, and the utilization rate of powder improves.
Accompanying drawing explanation
Fig. 1 is the sectional view of this utility model powder spray nozzle.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model being described in detail, the description of this part is only exemplary and explanatory, and protection domain of the present utility model should not have any restriction effect.
A kind of powder spray nozzle as shown in Figure 1, including connecting tube 1 and anemostat 2, the cross section of connecting tube 1 is circular or square, its one end is connected with the spray gun providing powdery fluids, the other end connects with anemostat 2, both junctions are provided with dispersion seam 3, and powder will spray to workpiece from dispersion seam 3 and anemostat 2 port of export, improve the uniformity.
Anemostat 2 part stretches in connecting tube 1, and the length of inserting end is 10mm, and in the upstream of the entrance of anemostat 2, connecting tube 1 internal frame is provided with screw fan 4, and screw fan 4 is erected in connecting tube 1 through support 5; The powder come in by connecting tube 1, drives screw fan 4 to rotate, and powder is stirred and not easily unites, and amount of powder is dispersed through seam 3 ejection, and another part powder enters anemostat 2.
During work powdery fluids in part through dispersion seam 3 by uniformly discrete and form Uniform jet and spray to workpiece, another part enters anemostat 2, has the jet of directivity, sprays to workpiece, and the utilization rate of powder is improved.
The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, under the premise without departing from this utility model principle; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
Claims (3)
1. a powder spray nozzle, it is characterised in that: including connecting tube and anemostat, described connecting tube one end connects with the spray gun providing powdery fluids, and the other end connects with described anemostat; Described anemostat stretch into described connecting tube and between the two junction be provided with dispersion seam, described connecting tube internal frame is provided with screw fan, and described screw fan is located at the upstream of described anemostat entrance.
