Embodiment
See also Fig. 2 and Fig. 3, inventor of the present utility model be in order to understand the technical solution of the utility model better, below by embodiment particularly, and is described in detail by reference to the accompanying drawings:
See also Fig. 2 and Fig. 3, a kind of sodium-sulphur battery storage sodium pipe of the present utility model comprises core pipe 1 and the storage sodium pipe hemisphere 2 that is connected to core pipe 1 bottom, and the bottom surface of described storage sodium pipe hemisphere 2 is provided with the first through hole 21.
Also be provided with a dividing plate 3 between core pipe 1 and storage sodium pipe hemisphere 2 on this sodium-sulphur battery storage sodium pipe, dividing plate 3 stores up sodium pipe storage sodium pipe with sodium-sulphur battery and cuts off into two parts in up and down, at least be provided with second through hole 31 on dividing plate 3, Liquid Sodium in core pipe 1 first flows into storage sodium pipe hemisphere 2 from the second through hole 31, flow out storage sodium pipe hemisphere 2 from the first through hole 21 again, namely flow out sodium-sulphur battery storage sodium pipe.
Also be provided with one in this sodium-sulphur battery storage sodium pipe and be positioned at directly over the first through hole 21, and be connected with dividing plate 3 bottom surface elasticity, and can be with the plugging part 5 of described the first through hole 21 sealings.
In the present embodiment, this plugging part 5 comprises can be with the piston head 51 of the second through hole 31 sealing, connect spring 52 and the fuse 53 of piston head 51 and dividing plate 3 bottom surfaces, and the fusing point of fuse 53 is less than the fusing point of spring 52.Be that plugging part 5 is an elastic piston.
When sodium-sulphur battery storage sodium pipe runs into the breakage of ceramic electrolyte pipe, when Liquid Sodium leaks to positive pole with the liquid sulfur reaction, sodium-sulfur battery temperature is increased to the fusing point of fuse 53, and fuse 53 fractures are under the effect of spring 52, piston head 51 moves down, the first through hole 21 sealings are further flowed out and the liquid sulfur reaction thereby limited Liquid Sodium, thereby have also controlled the further rising of sodium-sulfur battery temperature, effectively avoid the generation of fire, greatly improved the fail safe of sodium-sulphur battery.
In the present embodiment; fuse 53 is made by 5356 type magnadures, and the content of magnesium in 5356 type magnadures is 5%wt, and its fusing point is 574 ℃; if the content of magnesium is worth lower than this; the Melting point elevation of fuse 53 is unfavorable for piston head 51 performance protective effects, and other aluminum alloy materials fusing point is too low; when the ceramic electrolyte pipe is not yet damaged; the fusing point of fuse 53 just reaches, perhaps contain can not with the element of at high temperature long-term co-existence of Na, therefore be unsuitable for being used as fuse 53.Spring 52 materials are Inconel718 type steel alloys, use the spring 52 of this material still can maintain rebound effect preferably under 600 ℃, and in the time of can effectively guaranteeing fuse 53 fusing, spring 52 still has the elastic force that piston head 51 is pushed down.
Battery is in running, when the ceramic electrolyte tracheal rupture, ceramic electrolyte intraluminal fluid attitude sodium can directly contact with the outer liquid sulfur of ceramic electrolyte pipe and react and emit a large amount of heat, when temperature rises to the fusing point of fuse 53, piston head 51 seals the first through hole 21 under the effect of spring 52, thereby stoped Liquid Sodium further to flow out, reacted with liquid sulfur, stoped the further expansion of sodium-sulphur battery danger.
In this embodiment, in order to guarantee the rapid landing of piston head 51, between piston head 51 and described piston shell, force of sliding friction must reduce, and therefore the roughness Ra 1 of the roughness Ra 2 of described piston outer casing inner wall and piston head 51 sidewalls is all less than 0.2mm.
In the present embodiment, 51 of piston heads rely on the pressure of springs 52 with the first through hole 21 sealings, and therefore for the first permanent shutoff of through hole 21, spring 52 must be in compressive state all the time.
In the present embodiment, fuse 53 is fixed on the top of described piston shell, i.e. the junction of described piston shell and dividing plate 3 bottom surfaces.
Basis in embodiment, the center that is fixed on dividing plate 3 bottom surfaces of fuse 53.
Those of ordinary skill in the art will be appreciated that, above embodiment illustrates the utility model, and be not to be used as restriction of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
