Description

The invention relates to techniques for spraying a liquid.

The closest technical solution to the claimed object is the nozzle according to patent RU No. 2427402, А62С 31/02 (prototype), containing a hollow cylindrical body with a swirl divider.

The disadvantage of the prototype is that the known design does not allow to achieve a given distribution of flows of fine droplets on the irrigation surface of the required area without increasing the flow rate of the liquid.

The technical result is an increase in the efficiency of fine atomization.

This is achieved by the fact that in the nozzle containing the hollow cylindrical body, an external thread is made in the upper part of the body for connecting to the nozzle of the distribution pipe for supplying liquid, and an external thread is made in the lower part of the body for connection with a swirl flow divider, while the body has the inner cylindrical chamber, which serves to supply fluid, and in the cylindrical chamber, coaxially to it, is installed with a gap relative to the inner side surface of the chamber the first swirl, which is in the form of a sleeve with a threaded external thread with a large step of a trapezoidal profile and fixed by means of an internal thread on the rod, which is fixed in its upper part by means of a strainer to the body, and the swirl flow divider is attached to the body by means of a clip having an internal thread and made in the form a ring to which a vortex flow divider is attached, which is attached to the housing by means of a clip 9 having an internal thread and made in the form of a ring to which a con a perforated surface connected with its apex in the lower part to a vertically arranged rod on which a second swirler is mounted, made in the form of a cone with a central hole and screw blades, covering the rod with a gap and resting in the lower part on a stop located horizontally and perpendicular to the rod, moreover, the top of the conical surface of the second swirler is directed to the top of the conical surface of the divider.

The drawing shows a nozzle diagram.

The nozzle with an active divider contains a hollow cylindrical body 1, in the upper part of which an external thread is made for connection to a fitting (not shown in the drawing) of a distribution pipe for supplying liquid, and in the lower part of the body an external thread is made for connection with a vortex flow divider 8.

In the housing 1 there is an inner cylindrical chamber 4, which serves to supply fluid. To create the greatest effect of the formation of a finely divided continuous phase of the sprayed liquid in the cylindrical chamber 4, coaxially mounted with a gap 7 relative to the inner side surface of the chamber 4, the first swirler 3, made in the form of a sleeve with a screw external thread with a large pitch of a trapezoidal profile and fixed by internal thread 6 on the rod 2. The rod 2 is fixed in its upper part by means of a strainer 5 to the housing 1.

The vortex flow divider 8 is attached to the housing by means of a clip 9 having an internal thread and made in the form of a ring, to which a conical perforated surface 10 is attached, connected at its bottom with a vertically arranged rod 11 on which a second swirler 13 is mounted, made in the form cone with a Central hole 12 and screw blades 15, covering with a gap the rod 11 and resting in the lower part on the stop 14, located horizontally and perpendicular to the rod 11, and the top the conical surface of the second swirler 13 is directed to the top of the conical surface 10 of the divider 8.

To the stop 14 of the vertically arranged rod 11, on which the second swirler 13 is mounted, a divider is attached, made in the form of a vertical, axisymmetric nozzle body 1, a rod 16, to the lower part of which at least three inclined spokes 17 are attached, at the free ends of which are facing toward the second swirler 13, the impellers 18 are mounted with the possibility of rotation around the axes of the spokes 17.

The nozzle with the active divider is as follows.

When the fluid is supplied to the housing 1 under the influence of a pressure drop of 0.4 ... 0.8 MPa in the chamber 4, thanks to the first swirler 3, vortex flows of liquid are created, which flow into the vortex flow divider 8, and with the successive passage of expanding fluid flows expiring through the gap 7 , there is a fan-shaped gas-liquid flow in the form of a shroud, implemented by the second swirler 13, made in the form of a cone 13 with screw blades 15.
