Abstract

The invention relates to the technique of rac-. dusting liquids with compressed air and can be used in the manufacture of atomizers for external mixing liquids. The purpose of the invention is to expand the operational capabilities of the atomizer while increasing the spray pattern. For this purpose, a groove section with a U-shaped profile mating with a V-shaped groove is made in the plate, while the outlet of the air supply channel is made in the groove portion with a U-shaped profile. The outlet may be made in the form of a slit, the width of which at the outlet is greater than 1.5-2 times its width at the inlet. The outlet may be made in the form of a group of three holes located in the same plane at an angle of 25-30 °. 2 C.p. f-crystals, 12 ill.

WITH

The invention relates to a technique for spraying liquids with compressed air and can be used in the manufacture of atomizers for external mixing liquids.

The purpose of the invention is to expand the operational capabilities of the atomizer while increasing the spray pattern.

Figure 1 shows schematically a spray gun with an outlet for supplying air in the form of a slit; figure 2 - section aa in fig. 1; in Fig.3-view B in Fig.1; figure 4 is a section bb in figure 1; Fig. 5 shows a spray nozzle with an air outlet in the form of a group of three openings in a horizontal plane; in Fig.6 - section GG in Fig.5; Fig.7 is a view of D in Fig.5; in Fig.8 - section EE in Fig.5; figure 9 - spray with a group of three holes in a vertical plane; in FIG. 10 - section

FJ in Fig.9; in FIG. 11 is a view 3 in FIG. 9; on fig. 12 - view. And on fig. 10,

The sprayer comprises a body in the form of a plate 1, a groove with a section 2 of a V-shaped profile passing into a section 3 of a U-shaped profile.

In the section with a U-shaped profile, a channel 4 for supplying air with an outlet is made in the plate.

The outlet of the air supply channel 4 in one embodiment can be made in the form of a slot 5 (Figs. 1-4), the width of which at the outlet is 1.5-2 times greater than its width at the inlet (Fig. 3.4).

B. In another embodiment, the outlet of the channel 4 can be made in the form of a group of three holes 6 located in the same plane, for example, horizontal (Figs. 5-8) with a node between adjacent openings of 25-30 °.

(AND

In the third embodiment, the outlet of channel A can be made in the form of a group of three holes 7. located in one plane, for example, vertical (Figs. 9-12), with an angle between adjacent openings of 25-30 °.

The sprayer operates as follows.

Compressed air through channel 4, a hole of 5.6 or 7, is supplied to a portion 3 of the groove with a U-shaped profile. A liquid is supplied from above the channel to section 2 with a V-shaped profile. The liquid flows uniformly along the channel along section 2 with a V-shaped profile. In this section, a fluid flow is formed, which is stable when it flows to the air supply channel, while this profile flows down when the spray gun is not only in a vertical position, but also in any

Claims (3)

1. A liquid sprayer comprising a body in the form of a plate with a V-shaped groove for draining liquid and a channel for supplying air with an outlet, and so that, in order to expand the operational capabilities of the sprayer with increasing spray pattern , a groove section with a U-shaped profile mating with a V-shaped groove is made in the plate, while the outlet is vertical to horizontal. With further runoff, the liquid from the area with the V-shaped profile passes to the area with the U-shaped profile, in which its fairly uniform distribution in the form of a thin film occurs. The best results are obtained when the length of the section with a U-shaped profile is 5-10 times less than the length of the section with a V-shaped profile. Once in section 3 with a U-shaped profile, the liquid is immediately exposed to compressed air, i.e. spraying. The implementation of the outlet of the channel 4 in the form of a slit or a group of holes located in one plane with an angle between adjacent holes of 25-30 ° (horizontal or vertical), provides an increase in the spray torch. the opening of the channel for supplying air is made in the area of the groove with a U-shaped profile. 2. The atomizer according to claim 1, characterized in that the outlet is made in the form of a slit, the width of which at the outlet is greater than 1.5-2.0 times its width at the inlet. 3. The sprayer according to claim 1, wherein the outlet is made in the form of a group of three holes located in one plane at an angle of 25-30 °. with / 0 At -J  FIG. 3 MF Fig. U fo and
