Definitions
- the invention relates to a solution for the handling of bulk material containing fines, which can lead to the formation of explosive dust / air mixtures.
- bulk material is understood to mean a granular or also lumpy mixture of natural and / or artificial origin which is present in a pourable form. These include, for example:
- aggregates For the handling of bulk goods u.a. the following system parts (hereinafter referred to as “aggregates”) are used:
- the o.g. Aggregates comprise moving parts such as e.g. Rotors (cell wheels), slide blades, screws, conveyor coils, tube chains as well as static parts such. Housing, baffles.
- moving parts such as e.g. Rotors (cell wheels), slide blades, screws, conveyor coils, tube chains as well as static parts such. Housing, baffles.
- these parts are made of metallic materials.
- metallic materials such as plastics, ceramics).
- Aggregates can cause dusts to form explosive mixtures both during normal operation and in the case of faults.
- the likelihood of an explosive dust / air mixture occurring in these aggregates may vary from "rarely and for a short time (corresponding to a zone 22)" to "occasional” (corresponding to a zone 21) to "continuous, long term or frequently recurring" (corresponding to FIG a zone 20) (Technical Rules for Industrial Safety -TRBS 2152, Hazardous Explosive Atmospheres - General- dated 15.03.2006)
- ignition-active mechanical sparks may occur.
- Friction even between similar ferrous metals and between certain ceramic materials, can cause localized heating and sparks similar to the grinding sparks. As a result, explosive atmospheres can be ignited. "This also applies to explosive mixtures in the sense of the Hazardous Substances Ordinance (Ordinance on the Protection against Hazardous Substances (also stanchverowski - GefStoffV) of 01.06.2015).
- an explosion in the relevant aggregate may possibly occur with transfer of the explosion into upstream and downstream plant components (eg pipelines, supply and discharge organs). Such an explosion may cause personal injury and / or property damage.
- One way to avoid an explosion in the abovementioned system components is to avoid the explosive mixture in the interior of the abovementioned system components, for example by inerting.
- Another way to avoid an explosion is to avoid the ignition sources.
- mechanically generated sparks impact and friction sparks
- this can significantly limit the use of an aggregate.
- mechanically generated sparks can occur due to the contact of the moving parts inside the units with each other and / or against the inner wall of the housing.
- the occurrence of mechanically generated sparks can take place by unintentionally registered in the unit metal parts that can strike both against each other and against the moving and fixed parts (including housing wall).
- aluminum bronzes (CuAl alloys) are used as material for the movable internals in the o.g. Aggregates and / or housings of o.g. Aggregates used.
- the object has been achieved by an apparatus according to claims 1 to 4.
- the product-contacted interior of the housing or the movable internals are lined with the aforementioned materials and / or coated.
- nickel-free aluminum bronzes as a material for the aforementioned applications. These were previously unknown for this application.
- AMPCO 25 of the company AMPCO Metal SA which has been tested and proven at the Physikalisch-Technische Bundesweg (Meyer, L., completion of the research project to investigate the Zünd effectiveness of mechanical sparks in the use of Bronze, ptb 2015-11).
- the proposed application of aluminum bronze involves the manufacture of the moving and / or static parts of the aggregates for handling bulk materials, both as a solid material and as a coating (eg coating, plating, gluing) onto a base body not made of aluminum bronze one of the usual in the art, for. B. machining shape according to the mechanical requirements.
