12And doping or modified product etc.
Used capital equipment is kiln (claiming again calcining furnace or sintering furnace) in the production process of above-mentioned material, and wherein most of use saggar that needs is as the container that holds material.The profile of saggar has multiple, and more common is square saggar.Square saggar profile characteristics are that bottom and sidewall have flat outer surface, opened upper end, side wall upper part and have passage etc.; Be easy to pile up, can take full advantage of furnace chamber space, the advantage such as convenient for production and be widely adopted because have.
The sidewall of its sidewall of the saggar of other shape and square saggar is the same to have flat outer surface, cause like this in technological operation, such saggar uses inconvenience, exists such as high temperature sagger and is difficult to carry out the shortcomings such as gripping, mobile difficulty is large in batches, is unfavorable for the raising of production efficiency.
The utility model content
The purpose of this utility model provides a kind of when carrying out technological operation, the saggar of being convenient to the high temperature gripping and moving in batches.
For addressing the above problem, a kind of kiln saggar of producing the electrode for lithium ion secondary battery dusty material of the present utility model, this saggar is polygon bottom surface box body, comprises the polygon bottom surface and is positioned at a plurality of sidewalls that vertically arrange on each bar limit, polygon bottom surface; Its end face opening of described saggar offers passage on the sidewall top, it is characterized in that: described saggar also comprises and being positioned at least two sidewalls, and the groove offered of level.
The bottom surface of described saggar is square.
Described groove is opened on non-conterminous two sidewalls.
Described groove is opened on all sidewalls of saggar.
The cross section of described groove is polygon.
The cross section of described groove is quadrangle.
The quantity of described groove on the single sidewall at its place is many.
The quantity of described groove on the single sidewall at its place is one.
Adopt the kiln saggar of the production electrode for lithium ion secondary battery dusty material of the utility model structure, in art production process, can use clamper by the groove on the saggar sidewall described saggar to be carried out clamping, thereby overcome the defective that saggar in the prior art can't gripping under the condition of high temperature, and be convenient to that a plurality of saggars are carried out batch and move, thereby Effective Raise production efficiency.The kiln saggar of production electrode for lithium ion secondary battery dusty material of the present utility model, simple in structure, production technology is easy, and cost is low, and is workable, practical, suitable promoting the use of.

Embodiment one:
As shown in Figure 1, 2, 3, a kind of kiln saggar of producing the electrode for lithium ion secondary battery dusty material of the present utility model, this saggar is the square bottom surface box body, comprises square bottom surface and is positioned at four sidewalls 2 that vertically arrange on each bar limit of square bottom surface; Its end face opening of described saggar offers passage 1 on sidewall 2 tops, and described saggar also comprises and being positioned on the sidewall 2, and level being used for of offering the groove 3 that saggar carried out clamping by clamper.
Described groove 3 is positioned on two sidewalls at least, and the quantity on the single sidewall at its place is one.When groove 3 only was positioned on two sidewalls, described two sidewalls were non-conterminous.
Certainly, for ease of from different perspectives saggar being carried out clamping, described groove 3 is preferably on all sidewalls that are opened in saggar.
For guaranteeing the stability when saggar is carried out gripping, avoid saggar to come off at the gripping utensil, the cross section of described groove 3 is polygon.In this embodiment one, the cross section of described groove 3 be shaped as orthohexagonal half.
Embodiment two:
As shown in Figure 4, a kind of kiln saggar of producing the electrode for lithium ion secondary battery dusty material of the present utility model, this saggar is the square bottom surface box body, comprises square bottom surface and is positioned at four sidewalls 2 that vertically arrange on each bar limit of square bottom surface; Its end face opening of described saggar offers passage 1 on sidewall 2 tops, and described saggar also comprises and being positioned on each sidewall, and on each single sidewall level and parallel offer be used for the groove 3-1, the 3-2 that saggar are carried out clamping by clamper.
The cross section of described groove 3-1,3-2 is quadrangle.
