Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of sodium-sulphur battery alkaline electrolyte earthenware sintering bracing or strutting arrangement of the present invention;
Fig. 2 is the structural representation be arranged in sintering frock of a kind of sodium-sulphur battery alkaline electrolyte earthenware sintering bracing or strutting arrangement of the present invention.
Detailed description of the invention
In order to understand technical scheme of the present invention better, be described in detail by reference to the accompanying drawings below by embodiment particularly:
Refer to Fig. 1, a kind of sodium-sulphur battery alkaline electrolyte earthenware sintering bracing or strutting arrangement 40 of the present invention, comprises ceramic mouth of pipe support ring 1 and support column 2.
Pottery mouth of pipe support ring 1 and support column 2 are coaxially arranged from top to bottom successively.
The cross sectional radius of pottery mouth of pipe support ring 1 is greater than the cross sectional radius of support column 2.
The central authorities of pottery mouth of pipe support ring 1 offer the through hole 3 of a through support column 2.
The bottom surface of support column 2 offers the mutually perpendicular link slot 4 of twice.
The material of sodium-sulphur battery alkaline electrolyte earthenware sintering bracing or strutting arrangement 40 is MgO or Na-β "-Al
2o
3, ability 1600 DEG C of high temperature, and not with electrolyte ceramics pipe generation chemical reaction, and there is good thermal shock resistance.
The sintering method using sodium-sulphur battery alkaline electrolyte earthenware of the present invention to sinter the sodium-sulphur battery alkaline electrolyte earthenware of bracing or strutting arrangement 40 comprises the following steps:
Step A, is inserted into sodium-sulphur battery electrolyte thin-wall ceramic pipe sintering frock by described sodium-sulphur battery alkaline electrolyte earthenware sintering bracing or strutting arrangement 40 inner.Refer to Fig. 2: base 10 is for supporting its top frock and electrolyte ceramics pipe biscuit 5.Ventilation ring 20 is placed on base 10, for keeping gas circulation inside and outside electrolyte ceramics pipe biscuit 5.Synchronous ring 30 is placed on ventilation ring 20, with electrolyte ceramics pipe biscuit 5 synchronous in sintering process.Support column 2 is through synchronous ring 30 centre bore and ventilation ring 20 centre bore, be placed on base 1, closely cooperate with the centre bore of ventilation ring 20, undercut 4 matches with the groove of ventilation ring 20, electrolyte ceramics pipe biscuit 5 inner and outer air pressure, atmosphere in sintering process is kept evenly, to be conducive to the consistency of performance improving electrolyte ceramics pipe.
Step B, is socketed in outside described sodium-sulphur battery alkaline electrolyte earthenware sintering bracing or strutting arrangement 40 by electrolyte ceramics pipe biscuit 5; Pottery mouth of pipe support ring 1 is placed in electrolyte ceramics pipe biscuit 5, supports the oral area of electrolyte ceramics pipe biscuit 5.
Step C, sinters electrolyte ceramics pipe biscuit 5.
D step, excises the oral area supporting section of the electrolyte ceramics pipe sintered and takes out sodium-sulphur battery alkaline electrolyte earthenware sintering bracing or strutting arrangement 40, for subsequent use after clean.
Pottery mouth of pipe support ring 1 supports the oral area of electrolyte ceramics pipe biscuit, ensures that burning till rear electrolyte ceramics pipe has good roundness.By calculating the oral area roundness of electrolyte ceramics pipe, we find, in the electrolyte ceramics pipe using sodium-sulphur battery alkaline electrolyte earthenware sintering bracing or strutting arrangement 40 to burn till, the ratio of oral area roundness in 1 ~ 1.01 scope reaches 94%; And in the electrolyte ceramics pipe not using sodium-sulphur battery alkaline electrolyte earthenware sintering bracing or strutting arrangement 40 to burn till, the ratio of oral area roundness in 1 ~ 1.01 scope is 62%.The oral area roundness of both contrasts can be found out, uses sodium-sulphur battery alkaline electrolyte earthenware sintering bracing or strutting arrangement 40 significantly to improve the roundness of burning till rear electrolyte ceramics pipe.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the present invention is described, and be not used as limitation of the invention, as long as in spirit of the present invention, all will drop in Claims scope of the present invention the change of the above embodiment, modification.
