Description

The invention relates to techniques for spraying liquid media and can be used in the chemical industry, spruce economy and other fields of national economy, if necessary, multi-spray liquid.

The object of the present invention is to increase the efficiency of the sprayer by increasing the uniformity of spraying and liquid around the perimeter of the treated surface and to obtain fine-dispersed drops.

This task is achieved in that the spiral atomizer comprising a cylindrical drive housing with a receiving chamber and supply channels and screw feed spirals according to the invention is provided with at least one spray screw spiral installed along the inner diameter with a gap between the outer diameter of the supply spirals and at least one drive with a nozzle connected to the end part of the spray spiral. The turns of the spray coil are rigidly interconnected. A rigid connection of the turns of the spray spiral is made in the form of plates placed between the two walls of the end part of the spiral, while the plates can be placed in parallel

. perpendicular or oblique to the central axis of the housing.

A rigid connection of the turns of the spray spiral is made in the form of rods,

and about: about

but a

 and:

connecting each coil of the spiral along the outer diameter. The angles of inclination of the supply and spray spirals are selected different, and the angles of inclination of the cross sections of the supply and spray spirals to the central axis of the casing are different. The wire cup is mounted concentrically to the housing and is placed in the fluid supply area and is made with windows on the protruding parts.

In FIG. 1 shows a spiral atomizer, section: in FIG. 2 is a view A in FIG. 1, a fragment of a plate placement parallel to its central axis; in FIG. 3 is a view A in FIG. 1, a fragment of a plate placement obliquely to its central axis; in FIG. 4 is a design view of a spiral atomizer with two atomizing helical spirals; in FIG. 5 is a view B in FIG. 1 fragment of radial placement of a plate; in FIG. 6 is a view B of FIG. 2, an oblique fragment of a plate.

. The spiral atomizer comprises a cylindrical drive housing 1 with a receiving chamber 2 and feed channels 3 and screw feed spirals 4, mounted on a pipe 5 mounted on the outer diameter of the housing 1.

In addition, the sprayer is provided with at least one spraying spiral spiral 6 installed along the inner diameter with a gap h between the outer diameter of the supplying spiral 4 and at least one drive nozzle 7 connected to the end part of the spraying spiral 6.

The turns 8 of the spray coil 6 are rigidly interconnected to increase its rigidity. A rigid connection of the turns 8 of the spray spiral 6 is made in the form of plates 9 placed between two walls 10 and 11 of the end part of the spiral 6, which ensures an increase in the dispersion of spray drops. The plates 9 can be placed parallel (Fig. 2) or obliquely (Fig. 3) to the central axis of the housing 1. The inclined placement of the plate 9 increases the area of their sprayed surface. The plates 9 (Fig. 5) can be placed perpendicular to the central axis of the housing 1. The rigid connection of the turns 8 of the spray coil 6 can also be made in the form of rods 12 connecting each coil 8 of the spiral 6 to the outer diameter. The directions of the inclination angles of the supply and spray spirals 4 and 6 are chosen different, which makes it possible to increase the uniformity of liquid spraying along the perimeter of the treated surface. The angles of inclination of the cross sections of the supply and spray spirals 4 and 6 to the central axis of the housing 1 are chosen different to increase the dispersion of the spray drops. Drive Cup 7

. mounted concentrically to the housing 1, placed in the region of the nozzle 13 for supplying liquid and made with windows 14 on the protruding parts 15 to prevent accumulation of sprayed liquid in the cavities of the glasses 7.

Spiral atomizer operates as follows.

Spiral atomizer operates as follows.

Fluid inlet 13

5 (Fig. 1) enters the receiving chamber 2 of the rotating housing T and, through the supply channels 3, is fed to the supply spirals 4, from which it enters the spraying rails 6. The spirals 6 rotate with a larger

0 by the rotation speed with respect to the spiral 4, or the direction of their rotation is directed in the other direction relative to the direction of rotation of the spirel 4. Spiral b can also be performed with another

the direction of the angle of elevation of the turns of the spirals in relation to the spiral 4 (for example, spiral 4 is made with the right angle of elevation of the turns, and spiral 6 with the left). The liquid entering the spraying spirals 6 changes the shape of the flame spray coming from the spirals 4 more evenly distributing the spraying liquid along the perimeter of the treated surface, as well as

additionally grinds large drops.

5 Sprayed liquid enters the surrounding area.

For spraying difficult to spray liquids, several spirals b are used (Fig. 4), which, rotating, increase

0 uniform distribution of fluid along the perimeter of the treated surface and reduces the number of large drops. The installation of the spirals 6 alternately at different angles to the central axis allows

5 to change the direction of movement of the sprayed liquid, providing a more thorough grinding of the droplets.
