Abstract

The invention relates to agriculture, namely to devices for spraying liquids. The aim of the invention is to reduce energy costs and improve spray quality. The atomizer consists of an atomizing body made in the form of a bowl 7, an electric motor 4 with an adjustable rotational speed, an impeller of the fan 8 for separating small droplets and a housing 1. The atomizer is mounted with a clearance relative to the fan casing 18 of the fan 2. In the casing 18 slit 19, constituting a part of the circumference of 100-150 °. Suction of small droplets is made only from that part of the torch that is used during the work. On the inner surface of the disk 2, a shaped annular groove 9 is formed along its periphery. In the groove 9, liquid is collected and directed for re-spraying. 1 hp f-ly, 3 ill.

The invention relates to agriculture, in particular to devices for spraying a liquid.

The aim of the invention is to reduce energy costs and improve spray quality.

FIG. 1 is a schematic diagram of the sprayer; in fig. 2 is a section 20 A-A in FIG. one; on fig.Z - section bb in fig. one .

The sprayer consists of a cylindrical body 1, to which a fastener with a stationary disk 2 with a flange 3, 25 where the electric motor i and the bearing unit 5 are mounted, are installed, the shafts are connected by a coupling 6.

A spraying bowl 7 is mounted on the shaft of the bearing assembly 5, to which the impeller 8 of the centrifugal fan is attached. The disk 2 on the periphery has a shaped groove 9 connected to the lower part of the housing 1,

having a collection of 10.

The housing 1 has a flange to which the hydrocyclone 11 is attached. To the rod 12, the sprayer is attached by the clamp 13 and can be installed at a different angle to the direction of movement due to the bolt 1k,

Fluid is supplied through nozzle 15. At the bottom of housing 1, a connecting hose 1b is installed for pumping the liquid for re-spraying. The spray bar is limited by the movable screen 17 for adjusting the angle of the liquid exit. A suction slot 19 is formed in the fan casing 18. The spraying bowl has a drainage hole 20 for pumping. The fixed disk 2 is installed relative to the casing 18 with a gap of 21.

The spray works as follows.

The fluid through the nozzle 15 is supplied to the rotating bowl 7 and sprays from its periphery under the action of centrifugal forces. Formed in process40

All the spraying coarse droplets are partially deposited on the inner walls of the housing 1 and flow down them into the collector 10, from which the resulting liquid through the hose 1b is pumped out for re-spraying.

The part of the flare, limited by the adjustment plates of the screen 17, extends from the slot of the housing 1 and moves down to the object being processed.

To save energy, the slit 19 of the casing 18 constitutes only a part of a circle (with an angle of about 150 °), equal to the part of the plume used. Small circles formed on this part of the spray cup are sucked from its edges by the air flow inside the housing 1. Small droplets that form on the edge of the spray bowl outside the suction slit 19 are partially deposited on the inner surface of the disk 2 and partially carried by the counter air flow inside the housing 1.

Droplets trapped with airflow inside the housing 1 partially settle on the blades of the impeller 8 and the inner walls of the housing 1, while the smallest ones not settled in the housing 1 are directed by the air flow into the hydrocyclone 11 where they settle. The resulting liquid collects in the lower part of the housing 1 and is directed through the hose 1b for re-spraying. Small droplets deposited on the inner surface of the disk 2 are collected in the shaped groove 9, which in the lower part is connected to the collector 10.

I

For pumping fluid in the system and measuring its flow through each of the nozzles, the spray bowl 7 has holes 20 through which (with a non-rotating bowl) the liquid flows into the housing 1 and is collected in a collector 10.
