Safety container for galvanic cells
The invention relates to a safety container for galvanic cells, comprising an outer container and at least one inner container, wherein the inner container forms the transportation space for the galvanic cells, wherein a cavity is formed between the inner container and outer container, wherein the inner container and the cavity between the inner container and outer container are provided with inert filling material, wherein the cavity is designed to be gas-tight in relation to the inner container and gas-tight in relation to the exterior surroundings of the safety container, wherein the inner container is connected to the exterior surroundings via at least one tube through the cavity, wherein a pressure valve and/or a connection to an exhaust-air system is arranged at the outer end of the tube.
1. A safety container for galvanic cells comprising:
an outer container and at least one inner container, wherein:
the inner container forms a receiving space for the galvanic cells;
a cavity is formed between the inner container and outer container;
the inner container and the cavity between the inner container and outer container are provided with inert filling material;
the cavity is configured to be gas-tight in relation to the inner container;
the cavity is configured to be gas-tight in relation to the exterior surroundings of the safety container;
the inner container is connected to the exterior surroundings via at least one tube having an inner end and an outer end, the tube extending through the cavity;
at least one of a pressure valve and a connection to an exhaust-air system is arranged at the outer end of the tube;
a sieve is arranged at the inner end of the tube;
the sieve is configured with impact protection in order to prevent the sieve from being damaged;
the outer container and the inner container are made of steel; and
parts of the inner container are rigidly connected to the outer container by welding.
2. The safety container of claim 1 , wherein the outer container and the inner container comprise a common releasable cover.
3. The safety container of claim 2 , wherein the cover is double-walled forming a cover cavity, wherein inert filling material is in the cover cavity.
4. The safety container of claim 2 , wherein one or more compression seals are arranged between the cover and one or more of the outer container and the inner container.
5. The safety container of claim 1 , wherein the filling material is a silicate.
6. The safety container of claim 1 , wherein a width of the cavity between an outer side of the inner container and an inner side of the outer container is at least 0.1 m.
7. The safety container of claim 1 , wherein the outer container and the inner container each comprise gas-tight feedthroughs for one or more of load cables and data lines.
8. The safety container of claim 1 , wherein the outer container and the inner container each comprise gas-tight feedthroughs for coolant lines.
9. The safety container of claim 1 , wherein the sieve is made from a material that is resistant to high temperatures.
10. The safety container of claim 1 , wherein the filling material has a melting point of greater than 900° C.
11. The safety container of claim 1 , wherein the filling material comprises expanded glass in the form of hollow glass granules.
12. The safety container of claim 1 , wherein the tube comprises at least one bend.
13. The safety container of claim 1 , wherein
the inner container has multiple sides; and wherein
the inner container is connected to the exterior surroundings via multiple tubes, wherein at least one of the tubes is arranged on each side of the inner container.
14. The safety container of claim 13 , wherein multiple tubes are arranged on each side of the inner container.
15. The safety container of claim 1 , wherein the inner container comprises one or more galvanic cells.
