Abstract

The invention relates to devices for spraying and applying liquids, and can be used for spray painting. The purpose of the invention is to reduce paint consumption for fogging. For this, the tubes connected to the collector are made with end caps at the inlet and communicated with the cavity of the collector through slots in the side wall. In this case, the grooves are angled 20-40 ° & to the radius of the tubes and at an angle to their longitudinal axis. The grooves of adjacent tubes are made with an opposite inclination to the radius and axis of the tube. 2 hp ff, 4 ill.

: The invention relates to a device for spraying and applying liquids; it can be used for spraying and is an improvement of the device for compressing a jet of paint by a paint spray gun according to the author. St. No. 784938. I The aim of the invention is to reduce paint costs for fogging.

FIG. 1 shows a device for crimping a jet of paint of a paint sprayer; in fig. 2 — node I in FIG. one; in fig. 3 - adjacent tubes with grooves; in fig. 4 is a section A-A in FIG. 3

The device contains a hollow cylinder 1, on

at the same time that the hollow cylinder 1 encloses the spray nozzle.

Then the air supply tube 3 is connected to a source of compressed gas (compressor) (not shown) and, preparing the spray gun for operation, install the required spray gun by moving disk 4 along cylinder 1. Due to the difference in diameters of the centers of the holes in the collector 2 and disk 4, change setting angle

10 tubes 5. When the disc 4 is moved to the collector 2, the exit angle of the air jet compressing the paint torch increases, and on the reverse movement it decreases. When compressed air enters the cavity of the tubes 5 through the slots 8, inclined under the angle of a rigidly fixed annular collection of 20-40 ° to the radius and to the longitudinal axis

a torus 2 with an air supply tube 3. On the hollow cylinder 1, an annular disk 4 is mounted with a possibility of longitudinal displacement with openings uniformly circumferentially.

In the hole of the disk 4 installed tube 5 with flexible sections 6 (rubber or polyvinyl chloride tubes).

The number of tubes 5 is chosen as the maximum and is limited by the design possibilities of the device.

Connected with the collector 2 tube 5 is made with end caps 7 at the entrance and communicated with the cavity of the collector 2 through the grooves 8 in the side wall.

The grooves 8 are made at an angle of 20-40 ° to the radius of the tubes 5 and at an angle to their longitudinal axis.

The grooves 8 of the adjacent tubes 5 are made with an opposite inclination to the radius and the longitudinal axis of the tubes 5.

The diameter of the circle passing through the centers of the holes of the collector 2 is smaller than the diameter of the circle passing through the centers of the holes of the annular disk 4.

To install the device on the spray gun 9, a detachable clamp 10 is provided, mounted on the air supply tube 3.

The device works as follows.

With the help of the clamp 10, the device is fixed on the spray gun 9 in such a pick-up, the air flow is twisted in a spiral.

At the outlet of the tubes 5, swirling air flows are formed which involve

20, the surrounding air is formed and an air screen forms, compressing the paint jet of the paint sprayer.

Twisting the airflows of adjacent tubes to opposite sides further enhances air trapping from

25 environment, increases the compression of the jet of paint and reduces the loss of paint on fogging.

Claims (3)

 1. A device for crimping a jet of paint from a paint sprayer by author. St. No. 784938, characterized in that, in order to reduce paint consumption for fogging, the tubes connected to the collector are made with end caps at the inlet and through slots in the side wall that are connected to the collector cavity, while the grooves are made at an angle of 20-40 ° to the radius of the tubes . 2. The device according to claim 1, characterized in that the grooves are made at an angle to the longitudinal tube axes. 3. The device according to paragraphs. 1 and 2, characterized in that the grooves of adjacent tubes are made with an opposite inclination to the radius and axis of the tube. at the same time that the hollow cylinder 1 encloses the spray nozzle. Then the air supply tube 3 is connected to a source of compressed gas (compressor) (not shown) and, preparing the spray gun for operation, install the required spray gun by moving disk 4 along cylinder 1. Due to the difference in diameters of the centers of the holes in the collector 2 and disk 4, change setting angle 10 tubes 5. When the disc 4 is moved to the collector 2, the exit angle of the air jet compressing the paint torch increases, and on the reverse movement it decreases. When the compressed air enters the cavity of the tubes 5 through the slots 8, inclined at an angle of 20-40 ° to the radius and to the longitudinal axis   oh 20-40 ° to the radius and to the longitudinal axis tube, there is a twisting of the air flow in a spiral. At the outlet of the tubes 5, swirling air flows are formed which involve 20, the surrounding air is formed and an air screen forms, compressing the paint jet of the paint sprayer. Twisting the airflows of adjacent tubes to opposite sides further enhances air trapping from 25 environment, increases the compression of the jet of paint and reduces the loss of paint on fogging.
