Technical field
The utility model belongs to crucible technique field, relates to a kind of cellular type multilayer tantalum crucible, is applicable to splendid attire tantalum powder shaped granule in the battery core production process of tantalum capacitor and in high temperature furnace, carries out high temperature sintering.
Background technology
Tantalum capacitor excellent performance is that in capacitor, volume is little and can reach the product compared with high capacitance.Tantalum capacitor utilizes tantalum as electrode, and tantalum is conductor, but is transformed into high-quality insulator in the time that it is oxidized.Tantalum capacitor profile is varied, can be made into and is suitable for surface-pasted small-sized and sheet type element, has adapted to the development trend of current electronic technology automation and miniaturization.Although tantalum raw material is rare, tantalum capacitor price is more expensive, but adopt in a large number high specific capacitance tantalum powder, add the Improvement and perfection to capacitor manufacturing process, tantalum capacitor has still obtained development rapidly, range of application expanding day, is not only applied in the field such as military communication, space flight, but also in popularization gradually in the products for civilian use such as Industry Control, video equipment, communication instrument.
In tantalum capacitor production process, after need to tantalum powder is compressing, put into high temperature furnace and carry out sintering to form particle, for convenience of tantalum powder shaped granule being sent into high temperature furnace and being come out of the stove smoothly completing after sintering, will ensure that container is high temperature resistant, the crucible of often selecting tantalum material to make carrys out splendid attire tantalum powder shaped granule and carries out sintering simultaneously.
In the prior art, need the gap that keeps certain while carrying out sintering between tantalum powder shaped granule, gap is larger, being heated can be more even, but the combustion chamber internal diameter of boiler is limited, and the shaped granule that tantalum crucible can splendid attire is limited, can reduce the product sintering amount of single, thereby reduce production efficiency; If the tantalum powder shaped granule packing into is too intensive, can cause again its inequality of being heated, have influence on the sintering quality of product.
Utility model content
In order to address the above problem, the utility model provides a kind of cellular type multilayer tantalum crucible, improves the permeability of tantalum crucible in the time of sintering and the effect of guarantee sintering quality thereby reached.
The utility model is achieved by following technical solution.
A kind of cellular type multilayer tantalum crucible, comprise crucible suspension bracket, be arranged at some tantalum crucibles and height spacer on crucible suspension bracket, described tantalum crucible bottom surface is processed with centre bore, on centre bore, weld a tantalum cylinder, described height spacer, between every two tantalum crucibles, is processed with equally distributed through hole on the bottom of described tantalum crucible and around sidewall of crucible.
Hole diameter on described tantalum crucible is 2-5mm.
Described crucible suspension bracket comprises pressure pin and pallet, and described pallet is fixedly connected with one end of pressure pin, between described tantalum cylinder inner wall and pressure pin outer wall, leaves gap; Described pressure pin upper end is processed with hook on hole; Described tray upper surface is processed with support rim.
The number of plies of described tantalum crucible is 1-5 layer.
The beneficial effects of the utility model are:
A kind of cellular type multilayer tantalum crucible described in the utility model, in the battery core production process of tantalum electric capacity, because the product of tantalum crucible institute splendid attire is solid particle, as long as ensure that the clear size of opening of tantalum crucible bottom is less than the size of product, the product being placed in tantalum crucible just can not leak down from hole; Tantalum is one of rare metal mineral resources, and machining small on tantalum crucible has not only increased the permeability of tantalum crucible, it is heated more even, to ensure product quality, and has reduced material usage, thereby has reduced its production cost; In addition, by multiple tantalum crucibles are sleeved on crucible suspension bracket, increase sintering product volume, improved the working (machining) efficiency of product.

Detailed description of the invention
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of cellular type multilayer tantalum crucible described in the utility model, comprise crucible suspension bracket 1, be arranged at some tantalum crucibles 2 and height spacer 3 on crucible suspension bracket 1, described tantalum crucible 2 bottom surfaces are processed with centre bore, on centre bore, weld a tantalum cylinder 22, tantalum cylinder 22 height are higher than the degree of depth of tantalum crucible 2, and described height spacer 3 is cylindrical shape, between every two tantalum crucibles 2, on the bottom of described tantalum crucible 2 and around sidewall of crucible, be processed with equally distributed through hole 21.
Hole diameter on described tantalum crucible 2 is 2-5mm, and the base diameter of product to be sintered is 5-10mm, is greater than hole diameter, and product to be sintered can not spill from the through hole of tantalum crucible 2 21.
Described crucible suspension bracket 1 comprises pressure pin 11 and pallet 12, and described pallet 12 is fixedly connected with one end of pressure pin 11; Between described tantalum cylinder 22 inwalls and pressure pin 11 outer walls, leave gap; Described pressure pin 11 upper ends are processed with hook on hole 111, and crucible suspension bracket 1 is equipped with suspension hook, are convenient to suspension hook, the tantalum crucible of high temperature once be lifted and come out of the stove after product sintering completes; Described pallet 12 upper surfaces are processed with support rim 121, make to leave gap between orlop tantalum crucible 2 bottom surfaces and pallet 12, ensure that the product in tantalum crucible 12 is heated evenly.
According to the combustion chamber height of high temperature furnace, the number of plies of described tantalum crucible 2 is made as 1-5 layer, and the concrete number of plies can be determined by every batch of product quantity to be sintered; Described height spacer 3 is provided with different height models, can adjust the gap H that needs increase according to the number of plies of the product quantity to be sintered in each tantalum crucible 2 and tantalum crucible 2, thereby select corresponding height spacer model H.
When tantalum powder shaped granule is carried out to high temperature sintering, the uniform particles that completes moulding is placed in each tantalum crucible 2, the tantalum crucible 2 of filling tantalum powder shaped granule is overlapped and installed on crucible hoisting frame 1 one by one, according to the tantalum powder shaped granule quantity that needs sintering, determine the product quantity of placement in every layer of tantalum crucible 2 and the number of plies of tantalum crucible 2, thereby determine the model of selecting height spacer 3, in the time that the number of plies of tantalum crucible 2 is less, can select the height spacer 3 that H value is larger, otherwise in the time that the number of plies of tantalum crucible 2 is more, select the height spacer 3 that H value is larger, to keep the position of each layer of tantalum crucible 2 in high temperature furnace to be uniformly distributed.After tantalum crucible 2 and height spacer 3 are assembled on crucible suspension bracket 1 successively, catch on the hook on hole on crucible suspension bracket 1 with suspension hook, cellular type multilayer tantalum crucible is slowly put into high temperature furnace center, closed high temperature bell, starts to carry out high temperature sintering.To be sintered completing, opens high temperature bell, carefully catches on the hook on hole on crucible suspension bracket 1 with suspension hook, by cellular type multilayer tantalum crucible slowly lifting come out of the stove, complete the sintering process of a collection of tantalum powder shaped granule.
