Active spreader for atomiser by kochetov

FIELD: machine building.

SUBSTANCE: liquid flow spreader is fixed to the end face surface of a captive nut in an active spreader for a nozzle. The spreader is of pin type in the form of a truncated tetrahedron attached to the end face surface of the captive nut. The tetrahedron ribs are pins with blades with stops being mounted on them. Thus rotation of blades is provided due to the flows outgoing from a throttle plate with a nozzle jet. The tetrahedron base ribs are also connected to the blades with stops being mounted on them, by the pins.

EFFECT: higher efficiency of liquid atomising.

The invention relates to spray the liquid.

The closest technical solution to the declared object is a spreader nozzle according to the patent RU NO. 2488038, A62C 31/02 (prototype), comprising a hollow cylindrical body with throttle washer, coupled with a cap nut, which is attached to the divider fluid flow.

The technical result - improving the efficiency of fine atomization of the liquid.

This is achieved in that the spreader nozzle, containing a hollow cylindrical body with external thread for connection to the fitting of the distribution pipeline for supplying a fluid and fixed in the bottom of the housing Union nut with divider fluid flow, and in the housing, coaxially him, is cylindrical hole in the upper part of which is mounted a strainer, and in the lower part of the installed throttle washer with nozzle to the end surface of the Union nut, symmetrically to the case, attached the divider fluid flow, which made rod type in the form of a truncated tetrahedron, fixed to the end surface of the Union nut, ribs which are rods with fixed on them blades with the stops so that there was the possibility of their rotation from the flows emanating from the orifice plate with the spray nozzle, thus re�RA the base of the tetrahedron is also connected by rods with fixed on them blades and stops.

The drawing shows the schematic of the divider to the nozzle.

The nozzle comprises a hollow body 1 consisting of a cylindrical part with external thread for connection to the fitting (not shown) of the distribution pipeline for supplying a fluid, and fixed in the bottom of the housing Union nut 6 with divider 7 of the fluid flow. In the housing 1, coaxially to it, is cylindrical hole 2, in the upper part of which is mounted the mesh filter 4, and in the lower part of the installed throttle washer 3 with the nozzle 5.

The divider 7 of the fluid flow attached to the end surface of the cap nut 6 and made rod type in the form of a truncated tetrahedron, fixed to the end surface of the Union nut 6, the ribs 8 which are rods with fixed on them blades 9 with the stops 10 so that was the possibility of their rotation from the flows emanating from the orifice plate 3 with the nozzle 5 of the nozzle, wherein the ribs of the base of the tetrahedron is also connected by rods with fixed on them blades and stops.

The injectors work with the active divider is as follows.

When applying the liquid in the casing 1 under the action of pressure difference of 0.4...0.8 MPa she rushes into the cylindrical hole 2 through the mesh filter 4, and then into the throttle washer 3 with the nozzle 5. From putt�EPA 5 the fluid flow hits the divider 7 in the form of a truncated tetrahedron, fixed to the end surface of the Union nut 6, the ribs 8 which are rods with fixed on them blades 9 with the stops 10 so that was the possibility of their rotation from the flows emanating from the orifice plate 3 with the nozzle 5 of the nozzle, thus increasing melkodispersnoi phase of the fluid spray.

The use of highly dispersed active dispenser described construction allows to obtain a uniform volume flow fine spray of droplets in the range of droplet diameters from 30 to 150 μm in the water supply pressure not exceeding 1 MPa.

The proposed construction of a spreader nozzle can be used as a fine spray in fire protection engineering in agriculture.
