Description

The invention relates to means for spraying liquids, solutions.

The closest technical solution to the claimed object is the nozzle according to the patent of the Russian Federation No. 2514862, F02C 7/24, containing a housing with a swirl chamber and a nozzle insert (prototype).

A disadvantage of the known nozzle is that it does not provide a wide spray pattern.

The technical result is an increase in spraying efficiency by increasing the spray pattern.

This is achieved by the fact that in the vortex nozzle containing the casing with the swirl chamber and the nozzle, the casing is made in the form of a supply fitting with a central hole, and rigidly connected to it and a coaxial cylindrical sleeve with an internal thread and an expansion chamber, coaxial to the casing, while being aligned with the casing in its lower part a nozzle made in the form of an inverted glass is connected to the sleeve by means of a thread, in the bottom of which a turbulent swirl of a fluid flow is made with at least two inputs inclined to the axis of the nozzle in the form of cylindrical holes located in the end surface of the nozzle, where a central cylindrical throttle hole is also connected to the nozzle mixing chamber connected in series with the diffuser output chamber, a divider is installed in the diffuser output chamber, made in the form of at least three spokes, each of which one end is fixed on the outer surface of the diffuser outlet chamber, perpendicular to forming its surface, and the other in the surface of the body of revolution, for example a, the axis of which coincides with the axis of the diffuser outlet chamber, and the rotation body itself is located in the lower part behind the slice of the diffuser outlet chamber, a diffuser is attached to the end surface of the cylindrical sleeve coaxial to the housing, the cut surface of which lies in the plane below the surface of the body of rotation of the divider, and the divider is made in the form of two spokes, each of which is attached with one end to the outer surface of the diffuser output chamber, perpendicular to forming its surface and, on the other, on an axis on which a rotation body made in the form of a ball is installed with the possibility of rotation, the center of which lies on the axis of the diffuser output chamber, while the surface of the rotation body made in the form of a ball mounted on the axis with rotation is made perforated, and in a cylindrical sleeve there is an acoustic unit made with a supply of compressed air in the form of a toroidal shell of rectangular cross section with resonant sleeves forming Helmholtz resonators connected by an input a hole for the entrance of compressed air with a cavity of the toroidal shell in which they are fixed, and the output of compressed gas from the acoustic unit is through the output throttle bushings, which are located in the lower part of the acoustic unit and are directed towards the mixing chamber of the nozzle, and to the surface of the body of revolution, made in the form of a ball mounted on an axis with the possibility of rotation, elements are installed that rotate it, for example, in the form of segments of screw blades.

The drawing shows a diagram of a vortex nozzle.

The vortex nozzle includes a housing 1, which is made in the form of a supply fitting with a central hole 3 and rigidly connected to it and a coaxial cylindrical sleeve 2, in which are located an acoustic unit and an expansion chamber 4, coaxial to the housing. A nozzle 6 is connected to the sleeve 2, made in the form of an inverted cup, in the bottom 7 of which a turbulent swirl of the fluid flow is made with at least two inputs inclined in the form of cylindrical holes 9 located in the end surface of the nozzle 6 formed by its bottom 7. In the end surface of the nozzle 6, a central cylindrical throttle hole 5 is also made, connected by means of a sleeve 8 to the mixing chamber 16 of the nozzle connected in series with the diffuser outlet chamber 17. Moreover, the effect tive passage section areas of inclined cylindrical holes 9, taken in combination, and the center hole 5 are equal.

The acoustic unit 10, located in a cylindrical sleeve 2, is made with a compressed air supply 11 in the form of a toroidal shell 13 of rectangular cross section with resonant sleeves 14 forming Helmholtz resonators, connected via an inlet 12 for the entrance of compressed air (or gas) with the cavity of the toroidal shell 13 in which they are fixed. The output of compressed gas from the acoustic unit 10 is carried out through the output throttle bushings 15, which are located in the lower part of the acoustic unit 10 and are directed towards the mixing chamber 16 of the nozzle.

It is possible that on the inner surface of the central cylindrical throttle hole 8, located in the end surface of the nozzle 5, helical grooves are made for additional twisting of the fluid flow (not shown).

The swirl nozzle works as follows.

The sprayed liquid enters the housing 1 through the central hole 3, then into the expansion chamber 4, coaxial to the housing 1. Then the liquid is directed to the nozzle 6 and through the central cylindrical throttle hole 5 with the sleeve 8 to the mixing chamber 16.

In the acoustic unit 10 with resonant sleeves 14, pressure surges of compressed air occur due to phenomena accompanying the operation of Helmholtz resonators. The dimensions of the toroidal shell 13 and the resonant sleeves 14 are determined by the required required pulsation frequency of the nozzle 6 of the gas-liquid flow emerging from the mixing chamber 16, which contributes to an increase in the fineness of the spray nozzle.

In the output diffuser chamber, a divider is installed, made in the form of at least three spokes 18, each of which is fixed with one end on the outer surface of the diffuser output chamber 17, perpendicular to its surface, and the other in the surface of the body of revolution 19, for example, a ball whose axis coincides with the axis of the diffuser output chamber 17, and the body of revolution 19 is located in the lower part, behind a slice of the diffuser output chamber.

It is possible that the surface of the body of revolution 19, the axis of which coincides with the axis of the diffuser output chamber 17, and the body of revolution 19 is located in the lower part, behind a slice of the diffuser output chamber, is made in the form of an ellipsoid, the small axis of which is axisymmetric to the axis of the diffuser output chamber 17 ( not shown in the drawing).

A variant is possible when a diffuser 20 is attached to the end surface of the cylindrical sleeve 2, coaxially to the diffuser chamber 17, the cut-off surface of which lies in a plane below the surface of the divider rotation body 19.

A variant is possible when the divider is made in the form of two knitting needles, each of which is fixed at one end on the outer surface of the diffuser outlet chamber 17, perpendicular to its surface, and the other on the axis on which the rotation body 19 made in the form of a ball is mounted , the center of which lies on the axis of the diffuser output chamber 17.

A variant is possible when the surface of the body of revolution 19, made in the form of a ball mounted on an axis with the possibility of rotation, is made perforated.

A variant is possible when, to the surface of the body of revolution 19, made in the form of a ball mounted on an axis with the possibility of rotation, elements are installed that rotate it, for example, in the form of segments of screw blades (not shown).

It is possible that on the inner surface of the central cylindrical throttle hole 5 located in the end surface of the nozzle 6, helical grooves are made for additional twisting of the fluid flow (not shown).

It is possible that in the body of revolution 19, the axis of which coincides with the axis of the diffuser outlet chamber, and the body of revolution is located in the lower part, behind the slice of the diffuser outlet chamber, resonance recesses (not shown) are made in the form of a cylindrical surface of different diameters and lengths that perform the functions of Helmholtz resonators, the dimensions of which are determined by the necessary frequency of pulsation of the fluid flow to increase the fineness of the sprayed flame.
