SU1436965A1 - Highly-dispersed aerosol generator - Google Patents

Abstract

This invention relates to devices for producing highly dispersed mechanical aerosols. The aim of the invention is to improve the spray quality by increasing the number of uniform droplets and the ability to control the dispersion. The generator consists of a housing 1, in which the installation is an electric motor 2, a pump 5, a fan, a metering nozzle and a multistage rotating atomizer, made in the form of a movably mounted perforated cylinders 3, the height of each subsequent center of the cylinder 3 is higher than the previous one allows you to capture particles of a certain size, and smaller ones; 4; coke

Description

carried to the atmosphere. By adjusting the height of the cylinders relative to each other, it is possible to adjust the dispersion of the droplets that are applied to the treatment of the object. In the metering nozzle, jets with the same cross section are installed at equal distances, and the smallest perforated cylinder is equipped with partitions installed m, between the jets, which allows for more uniform dispense liquid on the first cylinder, 1 s.p, f-ly, 2 sludge.

The invention relates to rural. namely, devices for producing highly dispersed aerosols that can be used in controlling pests and diseases of plants. For disinfection, veterinary and in medicine.

The purpose of the invention is to improve the quality of the spray by increasing the number of homogeneous droplets of the required size and the ability to control the dispersion of the droplets.

, Fig, 1 shows the constructive scheme of the generator; on figo2 - eechesh-ie sprayer

In case 1, an electric motor 2 is installed, on the shaft of which in the upper part there is a multi-stage rotary atomizer reinforced in the form of several concentric perforated cylinders 3 mounted with axial displaceability. At the lower end of the shaft of the electric motor 2 there is an impeller 4 axial fan and coupling To drive a centrifugal pump 5, the casing of which is fixed on extensions 6 "; the suction nozzle of the pump is connected through the rod 7 to the casing 1 (spray annular tank below). ) As well, the discharge - through a hose 8 with an adjusting cock 9 with a nozzle 10 having nozzles 11 residing within the spray over 3 provided with a reflector 12,

The generator works as follows.

When the electric motor 2 is turned on, the liquid from the housing 1, the center about the pump 5, is supplied through the nozzles 11 and the nozzles 10 to the walls of the perforated g-cylinder of the rotating atomizer, separated by beads. By action

By centrifugal force, it is dropped from the edges of the holes in the form of large and small satellite drops. Large droplets with large kinetic energy fall on the inner walls of the second perforated cylinder and the fluid in them is sprayed again into large and small droplets. Then large drops are deposited on the walls of the next cylinder and i are again sprayed into large and small ones. Large drops dropped from the last cylinder are deposited on the walls of the reflector 12 and flow down them into the housing 1.

The small droplets formed after each of the spraying stages are affected by the air flow generated by the fan passing through the gaps between the concentric cylinders and the perforation of the outer cylinder and discharged as an air-droplet jet.

In order to work with the suspensions, a large part of the pumping fluid may be returned back to the tank for mixing.
