RU2368432C1 - High-dispersion aerosol generator - Google Patents

Abstract

FIELD: engines and pumps.

SUBSTANCE: proposed invention aims at producing high-dispersion aerosol generator with adjustable output and dispersion, and at reducing metal content and labor input in its production. To this end, proposed generator has its inlet and outlet branch pipes aligned and opposed in the cover of one chamber. Aforesaid water pressure branch pipes are separated by open cylindrical surface whereon a nozzle is fitted furnished with controlling and metering device that feed water for sprinkling. Nozzle outlet communicates with T-like baffle-distributing chamber.

EFFECT: higher efficiency, adjustment of dispersion degree.

Description

The invention relates to the field of veterinary medicine, medical equipment and agriculture, in particular for highly dispersed aerosols.

A device for producing highly dispersed aerosols is known, including nozzles of the atomizer type located coaxially one against the other, air hoses, containers for mortar and supplying the solution by ejecting the nozzles, additional exit nozzles are installed concentrically to the nozzles (AS No. 353716).

However, the known device does not allow you to adjust the flow rate of the liquid supplied to the spray and thereby change the performance and dispersion of the generated aerosol. In addition, the device contains two containers connected by a molded case with inlet air pressure channels. The housing design is difficult to manufacture, has a significant metal consumption of non-ferrous metal, not resistant to aggressive environments, and the presence of two containers complicates the design and doubles the remainder of the nebulized drug, which is undesirable.

In the known device, the aerodisperse mixture from two ejection nozzles is supplied directly to additional nozzles without preliminary separation of the coarse aerosol.

The aim of the invention is to obtain a highly dispersed aerosol of adjustable performance, dispersion, as well as reducing metal consumption and labor intensity in the manufacture.

This goal is achieved by the fact that in the generator for obtaining highly dispersed aerosols, including a nozzle, a solution container and inlet air nozzles ending with additional outlet nozzles, a liquid tube, a cap, according to the invention, the inlet and outlet air nozzles are mounted coaxially in the lid of one container in diametrically opposite direction in the center, separated by an open cylindrical surface in which the nozzle is installed with a regulating and metering device. The nozzle outlet communicates with a T-shaped fender-distribution chamber.

In addition, in the outlet pipe there are spiral channels for supplying air to the nozzle, and the container and the cover are made of polypropylene and are hermetically sealed with a union nut.

The air entering the chamber through a spiral channel, due to the rotation of the air flow, ensures the separation of large-droplet aerosol in the fender-distribution chamber.

The chamber acts as a chipper and a distributor of aerodispersed mixture for further supply to the outlet nozzles.

Description of the invention

The proposed device (see drawing) includes a container (1) for dispersible liquid, hermetically connected to the cover (2) using a union nut (13), inlet (3) and output (4) nozzles are installed coaxially in the cover in a diametrically opposite direction along the center and are separated by an open cylindrical surface (5), in which the nozzle (6) is installed with a regulating and metering device for supplying liquid to the spray (12), while the nozzle outlet is in communication with the fender-distribution chamber (8).

The fluid is supplied to the nozzle by ejection through the tube (11), passing a control and metering device (12) containing a movable sleeve (16) to block the holes (14) in the liquid channel.

The generator operates as follows.

When connecting the device to a source of compressed air, the liquid from the tank (1) due to ejection and pressure is fed through the metering device (12) to the nozzle (6). The flow rate of the liquid supplied to the spray is regulated by the dosed air supply to the liquid channel (11). Performance control is achieved by changing the bore of the holes (14) using a mobile clutch (16).

The aerodispersed mixture from the nozzle during rotation acquires, due to the air passing through the spiral channel, rotational movement, which provides more efficient separation of the coarse fraction in the fenders-distribution chamber (8). Dividing in the chamber by hoses (10) into two components, the flow is directed to the output counter-directed nozzles (9).

The implementation of the device with the indicated distinctive features has shown its efficiency and effectiveness in achieving the goal.

The performance of liquid dispersion is regulated in the range from 20 to 350 ml / min with an aerosol particle size of up to 20 microns.
