Description

Easy-to-apply to devices for producing a multicomponent mixture and may find application in mechanical engineering and various technological processes as nozzles and sprayers.

Known disk atomizer, which is mounted on a shaft, ttifi disk with radial output i-aiM / ia and 1

The disadvantage of this atomizer is - - t. general spraying occurs in the radio direction (1st direction, there is no possibility to control the qualitative and quantitative composition of the mixture during operation of the device, it is necessary to force in / i perpd of the alla disk to rotate it from the blade-1 of the 1st energy source.

Another nozzle containing an enclosure with a cylindrical chamber located in the end wall of the casing has a nozzle mounted in the casing v with a rotor sawed onto it with a log. and

 i - | -. It rubbed into rotation and axial i-. . BY; bottom to the shaft for the supply of other components and (.

 the disgrace of such a P-P-h-m-a is limited only by spraying; r;: - i i p v when the mixture is cooked. In addition, the intense swirl of the sprayed medium resulting from its interaction with the blades of the rotating rotor is largely suppressed in the radial and axial channels as the mixture moves to the output nozzle and the outgoing spray of the sprayed medium is not sufficiently swirled.

The objective of the invention is to remedy these disadvantages: expanding the functionality of the sprayer by combining in one device the functions of displacement and spraying of several gaseous and liquid components, regulating the composition of the sprayed mixture during operation of the device, reducing the energy loss of the mixture swirling on the rotor blades when it enters to the exit nozzle

The goal is achieved. in an atomizer containing a housing with a cylindrical chamber, an output nozzle located in the end wall of the housing, a shaft mounted in the housing with a rotor with blades mounted on it, a channel (potentially located in the side wall of the housing for supplying one of the components to the blades rotor and bringing the rotor into rotation and the axial channel

made in the shaft for supplying another component, an additional tangential channel is made in the side wall of the housing for supplying a gaseous component to the rotor blades located diametrically opposite to the main tangential channel, an additional supply channel is made in the housing, and radial channels are made in the rotor, one of which is connected with an axial channel, and the other communicates with an additional supply channel.

In addition, the number of tangential and radial channels may at least correspond to the number of mixed components.

In FIG. 1 shows a General view of the spray, a longitudinal section; in Fig.2 is a section aa in Fig.1, for spraying a mixture of four components

 The sprayer includes a housing 1 with a cylindrical mixing chamber 2, an outlet nozzle 3 is made in the end wall of the housing 1. In the housing 1, a shaft 4 is mounted with a rotor 5 with blades 6 mounted on it. A channel 7 is tangentially located in the side wall of the housing 1 for supplying one of components on the blades 6 of the rotor 5 and bringing the rotor 5 into rotation. An axial channel 8 is made in the shaft 4 for supplying another component. An additional tangential channel 9 is made in the side wall of the housing 1 for supplying a gaseous component to the tongues 6 of the rotor 5 located diametrically opposite to the main tangential channel 7. An additional supply channel 10 is made in the housing 1. rotor 5 has radial channels 11 and 12. Channel 11 is connected to the axial channel 8. and channel 12 is connected to an additional supply channel 10. The number of channels 7, 9 and 11, 12 at least corresponds to the number of mixed components

i

During operation of the device, through the tangential channels 7.9, the mixed components B and the gaseous component C are supplied under pressure to the blades 6 of the rotor 5, which ensures the rotation of the rotor 5 with a high speed Components G and D supplied through the shaft 4 and rotor 5 under the action of pressure and centrifugal forces inertia is ejected through channels 11 and 12 into the mixing chamber 2, sprayed according to the shock and pneumatic principle. The atomized mixture is mixed by vortex flows and ejected through the nozzle 3 in the form of a volumetric torch. The axial vortex generated by the rotary rotor 5 ohfi rests on the intense turbulence of the atomized mixture emerging from the nozzle 3.

The supply of one or several components to the rotor blades under pressure ensures its rotation at high speed, which eliminates the need for a shaft drive from an additional energy source. Due to the rotation, the components entering along its radial channels are evenly distributed around the circumference of the rotor. Their interaction with the rotor blades and the components coming through the tangential channels under conditions of intense turbulization determines the qualitative mixing of all components and the uniform distribution of their mixture throughout the chamber volume.

The location of the outlet nozzle coaxial with the rotor directly in the end wall of the chamber in which the rotor rotates causes low energy losses of the mixture swirling on the blade ring and obtaining an intensively swirling Torch of the mixture at the outlet of the nozzle.

The composition and flow rate of the mixture can be controlled and changed during operation of the sprayer by varying the pressure of the supplied components of the igi by changing the number of channels used for supplying one or another component.

One of the main specific features of the spray nafint which should be attributed to the property is that the supplied liquid components are first sprayed and then mixed as the sprayed substances. This makes it possible to obtain a spray torch of a mixture from components with different parameters (for example, viscosity).
