[0039] Advantageously, the external container body 12 comprises in a downward region and laterally a protective casing 16, which is adapted to contain the vacuum pump 17 and the electrical system and is adapted to protect these elements against impacts of various kinds. The protective casing 16 is preferably made of carbon steel of appropriate thickness, for example equal to 5 millimeters.

[0040] The external container body 12 comprises in a downward region a plurality of supporting feet 22, preferably a supporting foot 22 at each lower corner of the external container body 12.

[0041] Advantageously, the external container body 12 comprises in a downward region at least one pair of fork guides 24, which are mutually parallel and are adapted to guide and accommodate inside them the forks of a forklift truck, and are therefore adapted to ensure the maneuverability of the container 10 during the movement step, protecting it against impacts with the forks of the forklift truck.

[0042] Advantageously, the external container body 12 comprises in a downward region a plurality of protective plates 26a and 26b, which are adapted to protect the discharge means 44 against impacts of various kinds, in particular against impacts with the forks of the forklift truck during the step of moving the container 10 for metallic scrap according to the disclosure.

[0043] Advantageously, the external container body 12 comprises in a downward region at least one protective plate 27, which is adapted to protect the protective casing 16 against impacts of various kinds, in particular against impacts with the forks of the forklift truck during the step of moving the container 10 for metallic scrap according to the disclosure.

[0044] The perforated internal container body, or internal cage, 36 is preferably provided by means of perforated carbon steel plates, which comprise on the surface a plurality of holes 38 for example having a circular shape and with a diameter comprised between 6 and 10 millimeters, these plates being mutually rigidly coupled by means of welds.

[0045] The perforated internal container body 36 preferably has the shape of a right parallelepiped and comprises an opening 37 at its upper face, this opening 37 being adapted to allow the collection of the scrap of a reactive metal, such as for example titanium chips, within the perforated internal container body 36.

[0046] The perforated internal container body 36 is adapted to contain the scrap of a reactive metal, such as for example titanium chips. By means of its plurality of holes 38, the perforated internal container body 36 is adapted to filter said scrap and to separate (solid-liquid separation) the cooling liquid comprised therein, which derives from the machining of the reactive metal. Typically, the cooling liquid comprises water.

[0047] The cooling liquid, by passing through the plurality of holes 38, falls onto the hopper-like bottom 42 of the external container body 12. The cooling liquid is then discharged via of the discharge means 44 before creating vacuum inside the container 10 by starting the vacuum pump 17.

[0048] As mentioned, the perforated internal container body 36 rests on the at least one supporting profile 28 of the external container body 12, once the perforated internal container body 36 is inserted within the external container body 12.

[0049] The perforated internal container body 36 comprises in an upward region a plurality of engagement eyes 40, preferably an engagement eye 40 at each upper corner of the perforated internal container body 36. The engagement eyes 40 are adapted to facilitate the grip of the perforated internal container body 36 during the steps of insertion in, or extraction from, the external container body 12.

[0050] The lid 32 is preferably provided by means of a carbon steel plate of appropriate thickness, for example comprised between 1.5 and 2 millimeters.

[0051] The lid 32 is arranged above the rim 29 of the external container body 12. The lid 32 comprises sealing means 34, such as for example a gasket or a continuous strip of sponge, which are arranged along the lower face of the edge 33 of the lid 32.

[0052] In particular, the sealing means 34 are extended along the contact surface between the lid 32 and the external container body 12, in particular between the lower face of the edge 33 of the lid 32 and the upper face of the rim 29 of the external container body 12, consequently ensuring maximum tightness.

[0053] The lid 32 comprises coupling means 14, preferably a plurality of closure of adjustable lever-based closure devices, which are adapted to couple the lid 32 to the external container body 12, consequently blocking the opening 13 of the latter. In particular, the lid 32 comprises a second portion of the coupling means 14. The coupling means 14 are preferably arranged along the edge 33 of the lid 32.

[0054] In one embodiment of the container 10 for metallic scrap according to the disclosure, the lid 32 is pivoted to the external container body 12 by virtue of coupling means 14 with variable adjustment, in order to allow adjustment of the hermetic closure of the container 10 depending on the compression of the sealing means 34.

[0055] The lid 32 is independent and has no fixed points of connection to the external container body 12 and therefore the lid 32 does not occupy space during the steps of insertion or extraction of the perforated internal container body 36 in or from the external container body 12.

[0056] The combined action of the coupling means 14 and of the sealing means 34 allows to isolate hermetically the vacuum chamber, preventing the passage of any fluid, in particular of air, and to create vacuum inside the container 10.

[0057] Advantageously, the container 10 for metallic scrap according to the disclosure, in particular the lid 32, comprises a vacuum gauge 46, which is adapted to measure the residual pressure of the vacuum chamber that has been created inside the container 10.

[0058] In practice it has been found that the disclosure achieves fully the intended aims and advantages. In particular it has been shown that the container for metallic scrap, particularly for safely storing and transporting scrap of titanium and alloys thereof, thus conceived allows to overcome the qualitative limitations of the background art, since it allows correct storage of the scrap of a reactive metal, maximizing the safety level in the subsequent step of its transport, mainly land transport but also air transport and sea transport.

[0059] An advantage of the container for metallic scrap, particularly for safely storing and transporting scrap of titanium and alloys thereof, according to the present disclosure resides in that it prevents the triggering of combustion, which might cause a fire, or even an explosion, of the reactive metal stored and transported inside it.

[0060] Another advantage of the container for metallic scrap, particularly for safely storing and transporting scrap of titanium and alloys thereof, according to the present disclosure resides in that it allows to minimize the exposure to air of the reactive metal, consequently reducing the contact of the reactive metal with the gases for which it has affinity, such as for example oxygen, nitrogen, hydrogen or mixtures thereof.

[0061] A further advantage of the container for metallic scrap, particularly for safely storing and transporting scrap of titanium and alloys thereof, according to the present disclosure resides in that it allows to facilitate the operations for storage of the reactive metal and to speed up the operations for loading said container before its transport.

[0062] Moreover, an advantage of the container for metallic scrap, particularly for safely storing and transporting scrap of titanium and alloys thereof, according to the present disclosure resides in that it allows good maneuverability, ensuring the integrity of all of its parts and protecting them against any impacts of various kinds which might compromise its operation.

[0063] Although the container for metallic scrap according to the disclosure has been conceived in particular for safely storing and transporting scrap of titanium and alloys thereof, it can in any case be used more generally for the safe storage and transport of metals having a high reactivity when hot with oxygen, nitrogen or hydrogen present in the air, i.e., of all metals that have a risk of fire or even explosion if heated and placed in contact with the air of the surrounding environment. In addition to the already cited titanium and alloys thereof, other examples of reactive material are magnesium (symbol Mg) and alloys thereof, and zirconium (symbol Zr) and alloys thereof.

[0064] The disclosure thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept. All the details may furthermore be replaced with other technically equivalent elements.

[0065] In practice, the materials used, so long as they are compatible with the specific use, as well as the contingent shapes and dimensions, may be any according to the requirements and the state of the art.
