SU1007746A1 - Electroaerosol generator - Google Patents

Description

The invention relates to a device for spraying liquids and powder - and can be used for coating, aerosol-therapy, conditioning, spraying of sediments.

A known electro-aerosol generator comprising a container for a material, a driving cylinder with elastic elements on the periphery are immersed by the lower part in a container for material, a rod mounted above the container parallel to the axis of the cylinder with the ability to interact with elastic elements of the latter, and a high voltage source 1.

A disadvantage of the known devices is the low dispersion of spraying, since elastic elements made in the form of blades capture a layer of material of considerable thickness. In addition, the device does not provide for the possibility of changing the dispersion of the aerosol and the direction of flow.

The purpose of the invention is to increase the dispersity of the electric aererzol.

This goal is achieved by the fact that in the generator an electrical aerosol containing a container for a material, a driving cylinder with elastic elements on the periphery, immersed in the container for the material, a rod mounted above the container parallel to the axis of the cylinder and interacting with the elastic elements of the latter the stresses, the elastic elements of the cylinder are made in the form of bristles, and the source of high stresses is connected to the rod.

In addition, in order to allow the flow direction to change, the rod is mounted for movement around the cylinder axis.

In order to provide the possibility of controlling the dispersion of the electrodynamic aerosol, the rod and the container for the material are mounted so that they can be moved relative to the axis of the cylinder in the radial direction.

FIG. 1 schematically shows an electric aerosol generator} in FIG. 2to. same, top view.

The electric aerosol generator contains a container 1 for a material (liquid or powder) and a driving cylinder 2 with elastic elements at the periphery, immersed by its lower part in a container for material. The elastic elements are made in the form of bristles 3. Above the tank 1 for the material parallel to the axis of the cylinder 2 is mounted with the ability to interact with the bristles 3 a rod 4 connected to a high voltage source (not shown). In order to provide

the change in the direction of flow of the electric aerial, the rod 4 is mounted for movement around the axis of the cylinder 2. In order to allow the dispersion to be controlled, the rod 4 and the capacity 1 for the material are installed with the possibility. movement relative to the axis of the cylinder 2 in the radial direction. The device works as follows

0 way. . .

Container 1. is filled with starting material, for example, water. A high voltage is applied to the rod 4 and the cylinder 2 begins to rotate, as a result

As the bristles wet down 3. A passage past the stem 4, the bristles bend and then abruptly straighten. The film of fluid on the villi is dispersed by inertial forces, and each particle of aerosol carries an electric charge of g.

. Depending on which configuration the torch is required, the bristles are arranged in a specific sequence. This allows for.

5 coatings to get on the substrate prints of various shapes. Thus, on a substrate moving relative to the cylinder, it is possible to nanoport images of letters, numbers, symbols, patterns, etc.

FIG. 2 shows a cylinder with a bristle arrangement, which provides a grounded substrate when moving, perpendicular to its imprint.

5 letters P.

If necessary vertical. torch then. the rod is installed / on the horizontal line drawn through the axis of the rotor (fig; 1), if necessary

If the horizontally directed torch is then installed, the rod is mounted on the vertical through the axis of the cylinder, etc.

To change the dispersion of the liquid aerosol, the bristle contacts of the electrode rod are varied, which

 is carried out by moving the latter relative to the axis of the cylinder in the E direction adially about the axis. If the rod touches only the tips of the bristles, the aerosol will be fine. With a larger penetration of the rod into the bristles, the dispersion of the aerosol will decrease.

5 Adjusting the dispersion and aerosol concentration can also be achieved by changing the depth of immersion of the cylinder 2 into the sprayed liquid, for example, by moving the bone 1 and the speed of rotation of the rotor.

The use of the proposed device makes it possible to obtain a highly dispersed stream of electroaerosol with both liquid and solid dispersed 5 phases.
