Description

(5) PIPE COLORING DEVICE

The invention relates to a coating technique, in particular, to tools for small works, and is intended for use in the production of construction and installation works in all sectors of the national economy.

A device for coating a cylindrical shaped article is known, comprising radially mounted rollers fixed along the perimeter of the opening sections encompassing the article tU.

The design of this device is complicated. To obtain a high-quality paint, several steps (passes) are required, which reduces its performance.

The closest to the described invention in technical essence and the achieved result is a device for painting pipes, containing a container for a coloring fluid and a separable ring with a porous element enclosing painted C2 pipe. Capacity is made of upper and lower sections.

The disadvantage of this device is the poor quality of the color of horizontally mounted pipes, since during the painting of the lower part of the pipe the red liquid is in the lower part of the tank section and does not sufficiently enter the porous

10 element (sponge). In addition, it is necessary to paint the products again, since the tank sections are installed with a gap and there are unpainted strips between them.

IS

The aim of the invention is to increase the productivity and quality of paint and expand technological capabilities.

This goal is achieved by

Claims (2)

20 that a pipe dyeing device containing a reservoir for coloring fluid and a separable ring with a porous element encircling the circumferential painted pipe according to the invention is provided with a second detachable ring with a porous element that is connected to the first cylindrical shell that forms a cavity with the painted pipe for the coloring fluid and connected to the container by means of a nozzle in which the roller is rotatably mounted during the painting process. The roller can be made with blades. FIG. 1 shows the proposed device; in fig. 2 shows the section A-A in FIG. one; in fig. 3 - oazoez bb in FIG. 1. The device includes a container 1 for a coloring fluid mounted on tapered rollers 2, split rings 3 with a porous element made, for example, of sponge latex plates. The split rings j are interconnected by a cylindrical shell 5, which forms a cavity for the coloring fluid with the pipe being painted. The container 1 is connected to the shell 5 by a pipe 6, in which the cork valve 7 and the roles 8 with blades are installed, which rotate during the painting process. Each of the split rings 3 has a hinge 9 and a spring-loaded button latch 10. The device operates as follows. In the initial position, the plug valve 7 is closed. The container 1 is filled with a colored liquid, the split rings 3 are opened and the circumferential pipe 11 is covered. Then, the rings 3 are automatically closed with the push-button latch 10 and the valve 7 is opened. The red liquid enters the cavity of the shell 5 through the pipe 6, enveloping the surface of the pipe 11 The capacity 1 is moved along the longitudinal axis ok | With sewed pipe 11 on tracks 2 and I. At the same time, the dye liquid continuously enters the cavity of the shell 5 under the action of the force of gravity, the roller 8, rotating, mixes the dye liquid, providing high-quality coloring, and the porous elements k remove excess a layer of dye liquid uniformly filling irregularities and roughness on the surface of the pipe. At the end of the painting, the pipes 11 close the plug valve 7, consume the remaining paint, open the latch 10 and remove the device from the colored pipe. The design of the device is simple and easy. compact and economical. The mass application of the device for painting pipes mounted in buildings is advisable. The economic efficiency from the introduction of a single device will be 7.5 thousand rubles. Claim 1. A device for painting pipes containing a container for a coloring fluid and a separable ring with a porous element that surrounds the pipe being painted circumferentially, characterized in that, in order to improve the performance and quality of painting and expand technological capabilities, it is equipped with a second detachable ring with the porous element, which is connected to the first cylindrical shell, which forms with the painted pipe a cavity for the coloring fluid and is connected to the container by means of a nozzle, in which rotatably mounted in the roller painting process. 2. The device according to claim 1, about tl and that the roller is made with blades.
