Abstract

An explosion-proof housing, preferably of the ‘flameproof enclosure’ protection type, wherein the housing comprises a plurality of, preferably cast, wall modules.

First claim

The invention claimed is:

1. An explosion-proof housing, the housing comprising a plurality of wall modules of a modular system for producing the housing, wherein each wall module of the plurality of wall modules comprises at least one protrusion for arranging an element in a correct position relative to the wall module, the at least one protrusion engages in a recess of the element, wherein each wall module of the plurality of wall modules forms a flange section for attaching a plate shaped element the arrangement of each flange section of the plurality of wall modules being worked, after the plurality of wall modules have been joined, so as to form a flat gap between each flange section of the plurality of wall modules and the plate shaped element.

2. The housing according to claim 1 , wherein the plurality of wall modules are cast wall modules, or the plurality of wall modules are made of sheet metal.

3. The housing according to claim 1 , wherein each wall module of the plurality of wall modules includes a pressure relief opening.

4. The housing according to claim 1 , wherein a pressure relief element is cast into each wall module of the plurality of wall modules including a pressure relief opening.

5. The housing according to claim 1 , wherein at least one side of the housing is closed by a plate-shaped element.

6. The housing according to claim 1 , wherein the plurality of wall modules form a flameproof gap with a preferably plate-shaped element.

7. The housing according to claim 1 , wherein each wall module of the plurality of wall modules comprises one or more stabilization extensions extending away from the each wall module of the plurality of wall modules.

8. The housing according to claim 1 , wherein the at least one protrusion is formed at a stabilization extension.

9. The housing according to claim 1 , wherein the at least one protrusion is welded to an edge of the recess.

10. The housing according to claim 1 , wherein the plurality of wall modules are integrally joined among one another.

11. The housing according to claim 1 , wherein lateral edges of the housing form part of the plurality of wall modules.

12. An explosion-proof housing, the housing comprising the plurality of wall modules of a modular system for producing the housing of claim 1 .

13. A modular system for producing an explosion-proof housing for producing a housing according to claim 1 .

14. The modular system according to claim 13 , wherein each of the plurality of wall modules are cast.

15. The housing according to claim 1 , wherein each of the plurality of wall modules includes a pressure relief opening.

16. A method for producing an explosion-proof housing, comprising the following steps:
providing cast wall modules; and
assembling the housing from the cast wall modules, wherein each cast wall module comprises at least one protrusion for arranging an element in a correct position relative to the cast wall module, the at least one protrusion engages in a recess of the element, wherein each cast wall module forms a flange section for attaching a plate shaped element the arrangement of each flange section of the cast wall modules being worked, after the cast wall modules have been joined, so as to form a flat gap between each flange section of the cast wall modules and the plate shaped element.

17. The method according to claim 16 , the method comprising the following steps: arranging the cast wall modules to form the housing or a substructure of the housing; aligning the housing or the substructure of the housing; and fixing an alignment of the housing or the substructure of the housing.
