Abstract

The work consisted in the design and simulation of a "Glove Box" type controlled atmosphere vacuum chamber, which can meet the work requirements of the personnel of the Condensed Matter Laboratory. This system is based on the extraction of air inside the chamber, to be replaced by an inert gas, such as argon or nitrogen, so that the humidity levels are low enough to work with substances that are highly reactive to air. . The system is formed by the structure of the camera; a vacuum pump; pressurized containers of inert gases; analogous elements, such as pressure gauge and relief valves; neoprene gloves; additional accessories, such as lighting and electrical connections; a pre-chamber, which will work in a similar way to the main chamber, whose purpose will be to transport objects or samples inside the main chamber, without contaminating the interior of it. The "Inventor" software was used for the design and simulation of the structure, subjecting it to the maximum load that it must support, seeking an adequate safety factor. It also shows material selection criteria, through the use of CES edupack software; the calculation of the appropriate dimensions for the design, according to the ASME code section VIII, for the design of pressure vessels. Finally, the result is presented, this being the three-dimensional assembly of the vacuum chamber structure and all the elements coupled in a virtual way, together with the corresponding manufacturing and assembly plans.
