Abstract

The invention relates to agricultural machinery, in particular, devices for spraying liquids or simultaneously spraying and blending liquid components. The purpose of the invention is to expand the operational capabilities of the sprayer while improving spray quality. To do this, a conical swirler is mounted in the mixer of the mixer with the possibility of axial movement and fixing its position with a gap to the inner surface of the conical nozzle. The gap forms a cavity communicating at the exit with the cavity of the swirling chamber. An axial channel is provided in the cone vortex for communication with the atmosphere or a source of compressed air or liquid. The cone head and the twisting chamber are mounted with the possibility of axial movement and fixation of their position. Fluid through the cavity between the conical swirl and the conical nozzle and out of the vortex chamber is thrown into. droplets form a hollow torch with a reduced pressure area. As a result, air is sucked out of the axial channel, contributing to an increase in turbulence, intense vibrations of the liquid film and an improvement in its fragmentation. 1 3.p. f-ly, 1 ill. g (L

Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to devices for spraying liquids or simultaneous disintegrating and mixing of liquid components.

The purpose of the invention is to expand the operational capabilities of the kneader mixer while improving the quality of paint.

The drawing shows a spray-liquid mixer in cross section, a general view.

The spray-mixer of the liquid contains a case 1 with an inlet tangential | pip nozzle 2, a conical nozzle 3 placed therein with a conical swirl 4 installed inside it with an outer screw surface 5, a conical swirling chamber 6 with a tangential nozzle 7, and a conical swirl 4 installed with the possibility of axial movement and fixation of its position with a gap to the inner surface of the conical nozzle 3, forming a cavity 8, communicating at the outlet with the cavity 9 of the swirling chamber 6 and made with the axial channel 10, ayuschims with shtu- tserom 11 provided with a plug valve 1 February.

In this case, the cone nozzle 3 and the twisting chamber 6 are mounted with the possibility of axial movement and

fixing their position.

Spray-mixer works as follows.

The tangential nozzles 2 and 7 are pressurized under pressure into the housing 1 and the curling chamber 6, where they receive intensive rotation.

Having received a twist in the housing 1, the liquid enters the screw surface 5 of the swirler 4, where it acquires an even greater rotational speed and is ejected from the cone nozzle 3 in the form of small droplets, forming a hollow torch.

The fluid ejected from chamber 6 also forms a hollow torch, with a reduced pressure area inside each of them, which contributes to the ejection suction through channel 10 through air nozzle 31 into the center of the air vortex inside the torch and a significant increase in turbulence vortex, and this leads to intense fluid fluctuations

film, improving the quality of crushing its 5 reduction of polydispersity and greater dispersion of droplets over the cross section of the torch with a significant reduction in energy consumption for crushing the liquid,

Dispersed cone flares are layered, combined into a common torch, which, deposited on the treated surface, form a circle, providing a virtually uniform distribution of droplets on the treated surface.

The hydraulic parameters of the liquid sprayer: the capacity of the sprayer (flow rate), the spray angle, the degree of dispersion of the liquid, the polydispersity and the distribution of droplets on the surface to be treated at a given head are adjusted by twisting or turning the cone nozzle 3 of the twisting chamber 6 and the swirl 4 relative to the cone nozzle 3. Such adjustment can achieve optimal and desired hydraulic and dispersion characteristics.

If it is necessary to work the compressor with a supply of compressed air or an additional liquid component into the channel 10, a hose is connected to the fitting 11 from a source of compressed air or a container, and the cork 12 adjusts the amount of the supplied agent.

The proposed sprayer can be widely used as a dosing-mixer when feeding 4 nozzles 4 and 7 and a swirler channel 4 to 4 different liquids or other liquid components.
