With one heart, while the high temperature disc spring 13 in disc spring envelope pressure device 1 is in compressive state.
High temperature disc spring 13 is depressed into setting position under the action of press, ceramic insulation ring 43 and sulphur pole sealing ring 42 are provided
And it carries out being pressed required initial pressure between sodium pole sealing ring 44.
Finally disc spring outer cover 14 and lower sleeve portion 21 are locked with anchor ear 3, form lower limit device 2, disc spring envelope press fitting
Set the fixation between 1 and sodium-sulphur battery component.
Lower limit device 2, disc spring envelope pressure device 1 and sodium-sulphur battery component are integrally moved into progress metal pottery in vacuum drying oven
The hot-press sealing of porcelain.The time of hot-press sealing is 15~30 hours.
By the lower limit device 2, disc spring envelope pressure device 1 and sodium-sulphur battery component is whole takes out out of vacuum drying oven, puts to pressure
Preset position under machine, disassembly clip locks bolt 33 and clamp connection pin 32, and is made using demoulding power-assisted bolt 34
Anchor ear 3 is detached from, and first removes disc spring envelope pressure device 1, further takes out sodium-sulphur battery solid electrolyte ceramic pipe 41, pottery that sealing-in is integrated
Porcelain insulating ring 42, sulphur pole sealing ring 43 and sodium pole sealing ring 44, i.e. sodium-sulphur battery component.
Using a kind of metal to ceramic sealing tooling for sodium-sulphur battery production of the invention, wanting for equipment can be substantially reduced
It asks, effectively improves the efficiency of ceramicto-metal seal in sodium-sulphur battery, established technical foundation for sodium-sulphur battery ceramicto-metal seal.
A kind of metal to ceramic sealing tooling for sodium-sulphur battery production of the invention, lower sleeve portion 21 and disc spring outer cover 14
Due to being acted at high temperature by larger pressure for a long time, high-temp and high-strength material, the present embodiment middle and lower part sleeve 21 and dish are needed
Spring outer cover 14 is all made of the 3Cr13 alloy by quenching treatment as substrate.Lower sleeve portion 21 and disc spring outer cover 14 are rim of the mouth
Structure, high temperature disc spring 13 is damaged because load is excessive in order to prevent, and in the rim of the mouth of lower sleeve portion 21, i.e. the inner periphery of bottom is set
Sulphur pole support portion 211 plays the role of support limit to sodium-sulphur battery component.
The present embodiment high temperature disc spring 13 uses the Ni90 material of high temperature resistant, high-yield strength.
Clip 31 is using the H13 high-temperature steel Jing Guo modifier treatment in the present embodiment, due to the meeting in hot pressing of clip 31
For a long time by high temperature, high bounce effect, therefore, the clamp connection pin 32 of jointing clip 31 is needed with hard alloy material
Material；It is thick screwed tooth structure that clip, which locks bolt 33 and the thread of demoulding power-assisted bolt 34,.
Disc spring is sealed in pressure device 1, and guide rod 12 plays guiding role in high temperature disc spring 13 in disc spring, disc spring support ring 11
Outer diameter is 0.10-0.15mm smaller than 141 internal diameter of cover body of disc spring outer cover 14, so that the cover body 141 of disc spring outer cover 14 is played outer guiding and makees
With uniform force of the guarantee high temperature disc spring 13 in pressure process prevents high temperature disc spring 13 to be permanently deformed, also ensured sodium pole
The depth of parallelism after sealing ring 44, sulphur pole sealing ring 42 and 43 sealing-in of ceramic insulation ring.
The sulphur pole limiting section 221 and 25 top surface around the outer circle of sodium pole sealing-in briquetting of sulphur pole sealing-in cushion block 22 are mended around sealing-in height
The compensation ring limiting section 251 for repaying the setting of ring excircle can guarantee concentricity of all parts in lower sleeve portion 21.
It is thickness 0.05-0.15mm stainless steel foil ring that the extremely anti-sticking gasket 23 of sulphur and the extremely anti-sticking gasket 24 of sodium, which glue, main to use
The adhesion of sulphur pole sealing ring 42 and sodium pole sealing ring 44 and tooling when preventing demoulding.Sulphur pole sealing ring 42 and sodium pole sealing ring
44 material is alumal.
Ring 45 among sulphur pole sealing-in between sulphur pole sealing ring 42 and ceramic insulation ring 43 is located at sodium pole sealing ring 44
The material of ring 46 is al-mg-si alloy or aluminium-silicon alloys, outer diameter among sodium pole sealing-in between ceramic insulation ring 43
For 60~150mm.
The material of ceramic insulation ring 43 is 99 α-Al2O3, the material of solid electrolyte ceramic pipe 41 is β "-Al2O3, ceramics
Pass through glass sealing between dead ring 43 and solid electrolyte ceramic pipe 41.Since the thermal conductivity of glass is poor, in vacuum drying oven
When carrying out hot-press sealing, the heating rate of vacuum drying oven must not be higher than 2 DEG C/min, and rate of temperature fall must not be higher than 4 DEG C/min.
A kind of metal to ceramic sealing tooling for sodium-sulphur battery production of the invention is used for the ceramic insulation of sodium-sulphur battery
When ring 43 and sodium pole sealing ring 44 and sulphur pole sealing ring 42 carry out packaging by hot pressing, the vacuum degree of vacuum drying oven is first evacuated to 2.0 ×
10-2Pa, is then then turned on heating, and hot-pressing high-temperature stage vacuum degree must not be higher than 5.0 × 10-3The maximum temperature of Pa, vacuum drying oven is
570~590 DEG C, the highest temperature 120~200min of soaking time, 1.0~2.0 tons of the pressure of high temperature disc spring.
Heating wire material used in vacuum drying oven is Cr20Ni80 alloy, can meet progress high temperature pickup during heat pressing process
Requirement.When hot pressing, in temperature-fall period, when the temperature of vacuum drying oven at 200 DEG C and it is following when, let out vacuum, pressed together with being sealed to disc spring
Device 1, lower limit device 2 and sodium-sulphur battery component carry out integral high-temperature pickup, are transferred to cooling in incubator, incubator
Rate of temperature fall must not be higher than 5 DEG C/min.
In order to improve yield, can be brazed by way of increasing sealing-in tooling quantity in vacuum drying oven or using continuous vacuum
Furnace, that is, have the vacuum drying oven of continuous soldering function, i.e., the mode being brazed in continuous vacuum soldering oven, and foregoing invention can have
Conducive to the extensive industrial application of sodium-sulphur battery.
A kind of metal to ceramic sealing tooling for sodium-sulphur battery production of the invention, using anchor ear 3 for large-sized
Metal to ceramic sealing, and demoulded after sealing-in is good and be also not required to apply pressure to sodium-sulphur battery component again, it will not be to sodium sulphur electricity
Pond component impacts.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as the change in spirit of the invention, to embodiment described above
Change, modification will all be fallen within the scope of claims of the present invention.
