Embodiment 1

[0041] see Figure 5 to Figure 10 , a saggar 10 according to an embodiment of the present invention, the saggar 10 is mainly used in conjunction with a roller kiln 20 provided with a material turning drive assembly 21, and the saggar 10 is used to contain materials to be sintered (such as lithium battery positive electrode materials, etc. ), the saggar 10 containing the material to be sintered is placed in the matching roller kiln 20 to sinter the material. Depend on Figure 5 to Figure 10 It can be seen that the saggar 10 mainly includes a bowl body 11 and a material turning assembly 12 . The pot body 11 has an inner cavity 111 for holding the material to be sintered; the turning material assembly 12 is installed on the pot body 11, and one end of the turning material assembly 12 extends into the inner cavity 111, and the material turning material assembly 12 is used for The material to be sintered is turned under the driving of the turning drive assembly 21 in the roller k...

Embodiment 2

[0061] see Figure 1 to Figure 4 , a roller kiln 20 according to an embodiment of the present invention, the roller kiln 20 can be used together with the sagger 10 in the first embodiment of the present invention. Depend on Figure 1 to Figure 4 It can be seen that the roller kiln 20 is provided with a material channel 22, the material channel is provided with a roller table 23 for conveying materials, and the roller kiln 20 is provided with a turning component 12 for driving the sagger 10 to rotate, so as to The turning drive assembly 21 for turning the material to be sintered.

[0062] Specifically, see figure 1 , image 3 and Figure 4 , in this embodiment, the turning drive assembly 21 includes a plurality of blocking rods 211 arranged along the length direction of the material channel 22 of the roller kiln 20, and one end of the blocking rod 211 is connected to the inner wall of the kiln of the roller kiln 20, The other end of the blocking rod 211 is bent downward to...

Embodiment 3

[0069] see Figure 1 to Figure 4 , a sintering device according to an embodiment of the present invention, the sintering device is suitable for sintering a positive electrode material of a lithium battery, and the sintering device includes the saggar 10 of the first embodiment of the present invention and the roller kiln of the second embodiment of the present invention used together with it. 20. In this embodiment, the structure of the saggar 10 is the same as that of the first embodiment, and the structure of the roller kiln 20 is the same as that of the second embodiment, which will not be repeated here.

[0070] In the sintering device, when sintering, the saggar 10 enters the kiln from the inlet end of the material passage 22 under the action of the roller table 23 for sintering, and is sent out from the outlet end of the material passage 22; When running, when one of the four horizontal push rods 123 moves to the vertical rod 2111, it is blocked by the vertical rod 2111...

Abstract

The invention discloses a sagger, a roller kiln and a sintering device, wherein the sagger includes a bowl body which has an inner chamber for holding materials to be sintered; One end of the component extends into the inner cavity, and the turning component is used to turn the material to be sintered under the drive of the turning driving component in the roller kiln. The roller kiln is used in conjunction with the sagger, and the roller kiln is provided with a turning drive component for driving the turning assembly on the sagger to turn the material to be sintered. The sintering device includes the above-mentioned sagger and roller kiln. The sintering device can fully turn the materials during the sintering process, ensuring the complete sintering rate of the materials as a whole, improving the sintering quality and effect, and there are few structural changes to the roller kiln, the structure is simple, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of production of positive electrode materials for lithium batteries, in particular to a sagger, roller kiln and sintering device for sintering positive electrode materials of lithium batteries. Background technique [0002] The sintering device is more and more widely used in the field of sintering preparation of lithium battery cathode materials (such as lithium cobalt oxide, lithium nickel cobalt manganate, lithium manganate, lithium iron phosphate, etc.). [0003] During the sintering process of the positive electrode material of lithium battery, it is usually necessary to put the material into a special saggar, and then put the saggar on the roller table of the roller kiln and enter the material channel of the roller kiln for sintering. In the existing sintering device, the material accumulation in the saggar will not be flipped during sintering, resulting in incomplete and insufficient sintering of the ...
