Description

The utility model relates to technological equipment with the spraying of various materials and can be used in various industries for applying special coatings containing solid trace elements, as well as in research and development organizations involved in the development and research of various special coatings.

A known installation for pneumatic spraying of solid trace elements and fixing them on a solid surface, made in the form of a gun containing a housing, a handle and a trigger, kinematically connected with an air valve connected to a source of compressed gas, see patent of the Russian Federation for utility model No. 39839 class B05B 7/12, published on 08/20/2004 in Bulletin No. 23.

The apparatus has a container for a sprayable substance obtained by dissolving solid particles of various elements in a solvent. The known device cannot spray solid particles of various elements without dissolving them in a solvent.

Also known is an apparatus for pneumatically spraying solid microelements and applying them to a solid surface, comprising a spray gun with a spray head, a compressed air preparation and supply system connected to the spray gun, see Russian Federation Patent Utility Model No. 39287 Class B05B 7 / 12, published on July 27, 2004 in Bulletin No. 21.

The apparatus has a heated cell in which particles of solid elements are transformed from a solid state to a gaseous state and sprayed with compressed gas when the trigger is pulled.

The disadvantages of the known device are:

- the impossibility of pneumatic spraying of solid trace elements and reliable fixation on a solid surface without their destruction and without damage;

- the impossibility of spraying adhesive compositions into the bore;

- a narrow range of solid trace elements deposited on a solid surface.

In this utility model, the task is to create such an installation for pneumatic spraying of solid trace elements and applying them to a solid surface, which would cause:

- providing pneumatic deposition of solid trace elements without their destruction and damage to various solid surfaces with the simultaneous reliable fastening of solid trace elements on the treated surfaces;

- providing spraying of adhesive compositions and solid trace elements through a single spray head;

- the expansion of the range of solid trace elements is applied to various hard surfaces.

The solution to this problem is provided due to the fact that in the installation for pneumatic spraying of solid microelements and applying them to a solid surface containing a spray gun with a spray head, a compressed air preparation and supply system connected to the spray gun, the spray gun has two handles located at right angles to each other, each of which is connected to a compressed air preparation and supply system and has its own

trigger associated with a pneumatic valve that provides compressed air when the trigger is pressed:

- a container for glue connected to the channel for spraying glue with compressed air;

- a container for solid trace elements connected to a channel for spraying solid trace elements with compressed air;

- in this case, the channel for spraying glue with compressed air and the channel for spraying solid microelements with compressed air are made in such a way that they spray glue and solid microelements through a common spray head when you press the corresponding trigger.

The claimed installation for pneumatic spraying of solid trace elements and applying them to a solid surface has a combination of essential features unknown from the prior art for devices of this purpose, which allows us to conclude that the criterion of "new" for the utility model.

The essence of the utility model is illustrated using the drawing, which shows:

Figure 1 - General view of the installation (without pneumatic hoses connecting the spray gun with the system of preparation and supply of compressed air).

The device of the utility model is as follows.

Installation for pneumatic spraying of solid microelements and applying them to a solid surface comprises a spray gun (1) with a spray head (2), a compressed air preparation and supply system (3) connected to the spray gun.

The spray gun (1) has two handles (4), (5) located at right angles to each other, each of which is connected to the compressed air preparation and supply system and has its own trigger (6) connected to the pneumatic valve, providing compressed air when pulling the trigger:

- a container for glue (7) connected to a channel for spraying glue with compressed air;

- a container for solid trace elements (8) connected to a channel for spraying solid trace elements with compressed air;

- in this case, the channel for spraying glue with compressed air and the channel for spraying solid microelements with compressed air are made in such a way that they spray glue and solid microelements through a common spray head when you press the corresponding trigger.

The input of compressed air into the container for solid microelements is made tangentially, which ensures the turbulence of the flow of compressed air together with particles of solid trace elements in the tank (8).

When the unit is operating, the handle (5) is pressed and released with the left handle and a portion of glue is sprayed through the spray head (2) onto a hard surface. Then, the handle trigger (4) is pressed and released with the right handle and a portion of solid microelements is sprayed through the spray head (2) onto a portion of glue and glued to a solid surface.

The proposed utility model can be repeatedly made on the basis of materials commercially available by domestic and foreign industry using modern mastered technology and can be used in various industries for applying solid trace elements to a solid surface, as well as in research

organizations involved in the development and testing of various special materials, which allows us to conclude that the utility model meets the criterion of "industrial applicability".

In accordance with the proposed utility model, prototypes of the apparatus for pneumatic spraying of solid trace elements and applying them to a solid surface were made.

Their trial operation confirmed the advantages of the proposed utility model over known devices of a similar purpose. The possibility of reliable fixation of solid microelements of various shapes and sizes on various solid surfaces is noted.

Using the device raises the technological capabilities of production to a whole new level.
