The demand of battery is increasing, therefore the requirement to the yield and production efficiency of lithium battery is higher and higher.For this demand, lithium
Cell positive material producer develops multi-layer sintering technology, to improve production efficiency, reduces production cost.But current multilayer
Sintering technology is faced with positive electrode and burns between alms bowl there are reaction atmosphere unsmooth flowing, and positive electrode contacts unevenness with reaction atmosphere
Even problem leads to some local burning, and some place reactions are insufficient, and quality is different between layers, influences product matter
Amount.Meanwhile bowl, due to the swing of roller-way, often results in when into furnace and burns the case where alms bowl dislocation in turn results in stifled furnace.Current
Burning alms bowl in, remain in the positive electrode reactant not easy cleaning for burning alms bowl angle, to continuing to make below if not cleaning out
With impacting, thus usually need the cleaning that takes much time.
Utility model content
To solve the above-mentioned problems, the purpose of this utility model is to provide a kind of anode material of lithium battery to burn alms bowl, improves
The convection current of reaction atmosphere and the effect of heat transfer reduce and burn alms bowl and block up furnace risk, be convenient to clean residue.
The technical scheme adopted by the utility model is a kind of anode material of lithium battery burns alms bowl, it is characterised in that: including alms bowl
Body and spacer block, the bowl include rectangular alms bowl bottom and are disposed around alms bowl bottom surrounding alms bowl wall, and the alms bowl wall is square frame structure, institute
It states spacer block to be fixedly connected on the outside of alms bowl wall, the alms bowl bottom is smoothly connected with alms bowl wall.
As a further improvement of the above technical scheme, on the square frame at least one cornerwise two corners
It is respectively equipped with spacer block, the spacer block lower part is concordant with bowl lower end surface.
As a further improvement of the above technical scheme, the spacer block is L-type, and two bending sides of the spacer block are solid respectively
Surely it is connected on corresponding alms bowl wall.
As a further improvement of the above technical scheme, the spacer block is square block, and the spacer block is four pieces, described in four pieces
Spacer block is located on four faces of square frame.
As a further improvement of the above technical scheme, under four pieces of spacer blocks are located in four faces of square frame
Portion, four pieces of spacer block lower parts are concordant with bowl lower end surface.
As a further improvement of the above technical scheme, alms bowl wall upper end offers ventilation opening, four ventilation openings
Along alms bowl bottom center line symmetrical setting.
As a further improvement of the above technical scheme, the ventilation opening uses bow-shaped structural.
The utility model has the beneficial effects that the utility model outside alms bowl wall by being arranged spacer block, positive electrode multi-layer sintering
In the process, it needs to burn that alms bowl lay out in parallel is several to embark on journey, burn alms bowl and burns the presence between alms bowl due to spacer block, exist between every a line
There is ventilating duct, substantially increase the convection space of reaction atmosphere and heat, improves the convection effects of reaction atmosphere, positive electrode
What is contacted between reaction atmosphere is more abundant, improves the sintering quality of positive electrode.Meanwhile between bowl and bowl only
Spacer block is in contact, and reduces the contact surface between bowl, reduces the amplitude that bowl misplaces during into furnace, reduces bowl
The risk of stifled furnace.Alms bowl bottom and alms bowl wall, which are smoothly connected, can be improved the structural strength for burning alms bowl, reduces stress and concentrates, while being conducive to burn
The depanning of alms bowl, after the completion of subsequent reactions, smooth structure can be convenient the cleaning to residue.

Specific embodiment
The utility model relates to anode material of lithium battery burn alms bowl, including bowl 1 and spacer block 4, the bowl 1 includes rectangular
Alms bowl bottom 2 and the alms bowl wall 3 for being disposed around 2 surrounding of alms bowl bottom, enclose the alms bowl wall 3 set as square frame structure, are fixedly connected on the outside of alms bowl wall 3
Spacer block 4, alms bowl bottom 2 are smoothly connected with alms bowl wall 3.Alms bowl bottom 2 and alms bowl wall 3, which are smoothly connected, can be improved the structural strength for burning alms bowl, and reduction is answered
Power is concentrated, while being conducive to burn the depanning of alms bowl, and after the completion of subsequent reactions, smooth structure can be convenient the cleaning to residue.
The first embodiment as shown in Figure 1 and Figure 2 is fixedly connected with four spacer blocks 4, spacer block 4 in the four corners of alms bowl wall 3
For L shape, two bending sides of spacer block 4 are respectively fixedly connected on corresponding 3 face of alms bowl wall.It is burnt in multilayer anode material of lithium battery
It ties in technique, burns alms bowl and plurality of rows is needed to be layering, by the way that spacer block 4 is arranged, there are channels 6 between burning alms bowl and burning alms bowl, reinforce
The convection effects of reaction atmosphere.The presence of spacer block 4 simultaneously, reduces the contact area between alms bowl wall 3, reduces frictional force.
During into furnace, due to the shake of roller-way, burning alms bowl can be swung, often there is a situation where burning alms bowl dislocation, if dislocation is excessive
The case where will cause stifled furnace.Now by setting spacer block 4, the contact area between alms bowl wall 3 is reduced, is misplaced when burning alms bowl
When, the spacer block 4 for burning alms bowl and burning between alms bowl can disengage, and stopping continues to misplace, and reduce the amplitude of dislocation, reduce stifled
The risk of furnace.
Burning alms bowl multiple-layer stacked schematic diagram as shown in Figure 2 offers ventilation opening 5, each ventilation opening edge in the upper end of alms bowl wall 3
2 center line symmetrical setting of alms bowl bottom.Alms bowl is burnt when multiple-layer stacked discharges, and there are ventilation openings 5 between lower layer and upper layer, anti-saving
The circulation of atmosphere is improved while answering the space of furnace.It advanced optimizes, ventilation opening 5 is bow-shaped structural, and bow-shaped structural is conducive to
The molding of mold reduces production cost.
Fig. 3, Fig. 4 are the schematic diagrames of second of embodiment, and two partitions 4 are arranged in the side opposite the angle of alms bowl wall 3.Only need two
Spacer block has same technical effect simultaneously, can be further simplified the structure for burning alms bowl, reduces procedure of processing, reduces production.
Fig. 5, Fig. 6 are the schematic diagrames of the third embodiment, and spacer block 4 is designed as square block, and four pieces of spacer blocks are located at alms bowl wall 3
The middle and lower part in four faces, four pieces of spacer block lower parts are concordant with 1 lower end surface of bowl.Relative to two kinds of embodiments of front, this embodiment
While with same technical effect, the spacer block 4 of square structure is more easier machine-shaping relative to L shape shape spacer block 4, letter
Metaplasia production. art burns alms bowl and is more easier machine-shaping.
Certainly, the utility model is not limited to above embodiment, and those skilled in the art are without prejudice to originally
Equivalent deformation or replacement can be also made under the premise of utility model spirit, these equivalent variation or replacement are all contained in the application
In claim limited range.
