Abstract
An enclosing structure (S), in particular for enclosing and isolating outer environment of a packaging machine includes a plurality of enclosing panels (2), suitably and air-tightly assembled. At least one of the panels (2) defines a separating surface (1) for separating two different environments (A,B). Conveying means for conveying flows of purified air (F,F1,F2,F3,F4) are associated to the panel (2) to define, together therewith, a fluid-dynamic barrier, which avoids relative contamination between one environment (A) and the other environment (B).
Claims7
An enclosing structure(S), in particular for enclosing and isolating a packaging machine from the outside environment, the structure including:
- enclosing panel-shaped means (2), said panel-shaped means (2) including at least one separating surface defining panel (2) defining at least one separating surface (1) for separating two different environments (A, B);
- conveying means for conveying flows of purified air (F,F1,F2,F3,F4), associated to said separating surface defining panel (2) to form, together with said separating surface defining panel (2), a fluid-dynamic barrier avoiding contamination between one environment (A) and the other environment (B);
- the structure being characterized in that said panel (2) is defined by a first panel (3a) and second panel (3b), suitably air-tight assembled together and fastened to a frame (6) at a prefixed distance, to form an intermediate space (11), inside which a flow of purified compressed air (F) circulates;
- said first panel (3a) being turned toward said inner isolated environment (A), defining with said intermediate space (11) at least one conveying channel (21), which communicates with said inner environment (A) and through which a flow of purified air (F1) passes, directed solely toward the inner environment (A);
- and
- said second panel (3b) being turned toward said outer environment (B), defining with said intermediate space (11) at least one conveying channel (22), which communicates with said outer environment (B), and through which a flow of purified air (F2) passes, directed solely toward the outer environment (B).
