Description

The invention relates to apparatus for spraying and applying atmospheric corrosion inhibitors to hard-to-reach internal surfaces of mechanisms and systems of various configurations.

Known installation for the conservation of the internal surfaces of mechanisms and systems with volatile inhibitors and their solutions (Pat.80851 Russian Federation IPC C 23 F 11/02. Installation for the conservation of hard-to-reach cavity mechanisms with volatile inhibitors and their solutions [Text] / Kolesov VV, Tretyakov A.S., Matyash A.L., Sergeev A.Yu., Obukhov AM, Bogdanov A.A., Danilichev A.N., applicant and patent holder State educational institution of higher professional education Ryazan Military Automobile Institute named after Army General V. P.D Urynina - 2008128075/22, announced July 9, 2008; published February 27, 2009; Bull. No. 6) containing a container with a gas distribution device located in the lower part, an air supply and exhaust system made with a central tubular channel, and a filter located in the upper part of the tank, with an integrated temperature indicator, an ejector device in its upper part of the body, a special stand with an electric heater.

The disadvantage of this installation is the increased complexity of work when refueling the inhibitor, the inability to control the supply of inhibited air and retaining the inhibitor inside the unit during the warm-up period, and when the unit is switched to another conservation object, if necessary.

The technical result is aimed at improving technological capabilities, environmental safety of the installation and eliminating the harmful effects on the personnel performing the work.

The technical result is achieved by the fact that the installation for preserving the internal surfaces of mechanisms and systems with volatile inhibitors and their solutions, containing a container with a gas distribution device located in the lower part, an air supply and exhaust system made with a central tubular channel, a filter, an integrated temperature indicator, an ejector the device in its upper part, a special stand with an electric heater, while additionally equipped with a filling neck with a lid and two locking and cranes.

Distinctive features is that the installation is equipped with a filler neck with a lid and two shut-off valves.

The drawing shows the installation for the conservation of the internal surfaces of mechanisms and systems of volatile inhibitors and their solutions.

The installation is a vertical container consisting of a housing 1, a cover 4 and a special stand 2. The housing 1 in the lower part is made conical to give direction to the air stream entering through the tubular channel 3 for air supply, and is equipped with a special stand 2, in which an electric heater 13. A gas distribution device 5 is installed in the lower part of the housing 1, and a strainer 12 is installed in the upper part, which prevents the solid particles of the inhibitor carrier from getting into the discharge line and temperature collector 6. A fitting 7 with a shut-off valve 14 is installed in the cover 4 and connected to a central tubular channel 3 for supplying air to the cavity of the housing 1. In the upper part, the cover is equipped with a fitting with a screw-on shut-off valve 15 and an ejector device 9 with an inlet fitting 8 and output nozzle 10. In the side wall of the housing 1 is installed the filler neck 16 with a cover 17 for refueling the inhibitor.

The device operates as follows.

Inside the housing 1, through the filler neck 16, an inhibitor is poured liquid or dry in the form of powder or tablets, and closed by a cover 17. The filler neck 16 allows to reduce the filling time, to exclude the opening of the top cover 4 and thereby reduce the contact area of the inhibitor with the external environment and the effect on personnel performing conservation.

When preserving pneumatic systems of complex configuration and of a sufficiently large length, compressed air from the source is supplied to the inlet 8 of the ejector device 9 and to the outlet 10. At the same time, air through the inlet 7 and the central tubular channel 3 enters the internal cavity of the installation, where it passes through the solution or solid carriers of the inhibitor, saturated with its vapor. The ejection device draws inhibited air from the installation housing, and the shut-off valve 15 allows you to adjust the supply of inhibited air to achieve an appropriate concentration of inhibitor in the preserved cavity. Before heating the inhibitor with an electric heater 13 from the mains to the appropriate temperature, as well as after preservation, the taps 14, 15 are closed, thereby making it possible to hold the volatile inhibitor inside the unit.

When using solutions for the conservation of small-capacity mechanisms, the ejector device 9 is screwed from the shut-off valve 15. The shut-off valves 14, 15 are closed. Through the filler neck 16, the inhibitor solution is charged into the unit body 1. After filling and connecting the installation to the conserved object, the taps 14, 15 open, and compressed air through the shut-off valve 15 and the fitting 11 enters the cavity of the housing 1 of the installation. The pressure created inside the housing displaces the inhibitor solution through the central tubular channel 3 and nozzle 7 into the conserved object, providing processing of its internal surfaces. As the canned object is filled, the shut-off valves 14, 15 close, the air supply stops.

The proposed device is more perfect in comparison with the known, because has higher technological capabilities and eliminates the harmful effects on the personnel performing the work.
