Embodiment Construction

[0026] figure 1 A serviceable inert gas housing 10 is shown as an example. Such an inert gas housing 10 is used, for example, to accommodate production plants by means of which production processes can be carried out in a protected atmosphere. Nitrogen or argon, for example, can be used as inert gas.

[0027] The inert gas housing 10 has a working chamber 13 in which a production device, for example a machine 70 , is arranged. Fully automatic operating equipment is usually used in an inert gas enclosure, such as in figure 1 visible in . exist figure 1In the shown inert gas housing 10 , a plenum 11 is separated above a working chamber 13 by means of a cover 12 . In the bottom region of the inert gas housing 10 , a chamber 15 branches off by means of a bottom 14 . Of course, the invention can also be used in differently configured inert gas housings 10 in which, for example, no plenum 11 or no bottom-side chamber 15 is used. The inert gas housing 10 has a service opening ...

Abstract

The invention relates to a device for exchanging gas from a working chamber (13) of a serviceable inert gas housing (10), the device having a housing outlet line (50.1) connected to the inert gas housing (10) and by means of a housing outlet line, gas can be discharged from the inert gas housing (10), and wherein a housing inlet line (50.15) is provided, which is configured to, by means of a conveying device , preferably a blower (24) directs breathing air into the inert gas housing (10). In order to enable reliable breathing air monitoring of the inert gas housing at low cost, it is provided according to the invention that at least one sensor, preferably an oxygen sensor of the breathing air monitoring device (40), is arranged in the housing outlet line (50.1) (41).

Description

technical field [0001] The invention relates to a device for the reliable exchange of working gas into a safe breathing air atmosphere from a working chamber of a serviceable inert gas housing. This takes place via the housing outlet line, which is connected to the inert gas housing and by means of which the gas can be discharged from the inert gas housing, and the housing inlet line, which is configured As a result, the breathing air is introduced into the inert gas housing by means of a conveying device, in particular a blower. The status in the working chamber is continuously monitored via measuring instruments. [0002] Furthermore, the invention relates to a method for the reliable exchange of working gas from a working chamber of a serviceable inert gas housing into a safe breathing air atmosphere. This is achieved by means of housing outlet lines, housing inlet lines, measuring sensors and delivery devices, preferably breathing air blowers, which lead fresh air into t...
