Description
Technical field
The present invention relates to a kind of for roasting the exhaust of lithium ion battery electrode material and heat transfer multi-function device, belong to lithium
Cell positive material field.
Technical background
Anode material for lithium-ion batteries for example cobalt acid lithium, LiMn2O4, LiFePO4, nickel manganese high voltage material, ternary material,
In the preparation process such as rich lithium material, it usually needs fill the presoma of reaction raw materials or electrode material into powder by ground and mixed
Enter in dedicated saggar, then the multiple saggars for filling powder material are placed sequentially in roller bed type sintering furnace under certain atmosphere
It is roasted.The powder material of certain altitude (thickness) is filled in usually each saggar, when being sintered kiln roasting, due to powder
Body solid accumulation thickness is larger, influences to conduct heat, and on the one hand needs larger energy consumption, is on the other hand easy to cause the object of different parts
Expect that sintering temperature is uneven, therefore, it is difficult to ensure the homogeneity of product quality.In addition, the gas discharged inside material easily gathers
And material spray phenomenon often occurs, lead to loss of product or contaminated, the normal operation of roller-way furnace apparatus can be influenced when serious.
Invention content
The technical issues of in order to avoid present in the above-mentioned prior art, the present invention is intended to provide a kind of be used to roast lithium ion
The exhaust of battery electrode material and heat transfer multi-function device.Apparatus of the present invention and the saggar of firing electrodes material are used cooperatively, tool
Have in discharge electrode material heating process in time due to material dewatering or the two big function of gas and augmentation of heat transfer of decomposition release.One
Aspect outside material spray when lithium ion battery electrode material can be prevented to be sintered in saggar avoids causing material loss or influences roller
The normal operation of road furnace apparatus；On the other hand can make roasting heat air-flow uniformly and rapidly flow into inside the material in saggar into
Row heating has apparent energy saving and ensures that material roasts uniform effect.
The present invention is for roasting the exhaust of lithium ion battery electrode material and heat transfer multi-function device, including more porous rows
Gas heat-transfer pipe 1 and the fixed frame 2 for fixing porous exhaust heat-transfer pipe 1, porous exhaust heat-transfer pipe 1 and fixed frame 2 are whole
Body structure or composite structure.
The porous exhaust heat-transfer pipe 1 is the cylindrical shape exhaust pipe of bottom lock.Further, the porous exhaust heat transfer
The bottom of pipe 1 is set as inverted cone.Porous exhaust heat-transfer pipe compared with flat, is pressed into using inverted conical lower section
Resistance is smaller when inside material, is easy to exhaust pipe press-in saggar material bottom.
The porous exhaust heat-transfer pipe 1 is made to place, and all porous exhaust heat-transfer pipes vertically by the fixed frame 2
1 nozzle is in same level.
The fixed position of the fixed frame 2 and the porous exhaust heat-transfer pipe 1 makes the porous row in 2 lower part of fixed frame
The depth of the height of gas heat-transfer pipe 1 >=matching used saggar, so that fixed frame is made to be located above material.
The uniformly distributed venthole on the cylinder tube wall positioned at the porous exhaust heat-transfer pipe 1 of 2 lower part of fixed frame, for discharging gas
Body and augmentation of heat transfer.Inverted conical lower section is closed hollow-core construction, and tapered segment does not open stomata.
The fixation that the more porous exhaust heat-transfer pipes 1 pass through fixed frame 2 is in laterally or longitudinally or mixing rule arranges.
Handle 3 is provided on the fixed frame 2 to pick and place.
Present invention exhaust and the material of heat transfer multi-function device (including porous exhaust heat-transfer pipe 1, fixed frame 2 and handle 3)
Matter is identical with the material of saggar, generally the refractory materials such as ceramics, corundum or metal material, ruler of the geometric dimension according to saggar
Depending on very little.Wherein the material of fixed frame 2 can be identical or different with porous exhaust heat-transfer pipe 1, is refractory material.
The drum diameter of the porous exhaust heat-transfer pipe 1 is 3-100mm, wall thickness 1-50mm, and the general requirement of height is more than
The depth of saggar.Uniformly distributed venthole can be circular hole, square hole or other shapes hole on its cylinder tube wall, and pore size is according to powder
The size of particle can be in 50 μm of -10mm.
Apparatus of the present invention and the saggar of firing electrodes material are used cooperatively, and are had in discharge electrode material heating process in time
Due to material dewatering or decompose the two big function of gas and augmentation of heat transfer of discharging.On the one hand lithium ion cell electrode material can be prevented
Material spray phenomenon occurs due to the accumulated gases of inside release when expecting to be sintered in saggar, avoid causing material loss or influences roller-way
The normal operation of furnace apparatus；On the other hand roasting heat air-flow can be made uniformly rapidly to flow into material and be internally heated, had
There are apparent energy saving (energy saving 10~20%) and the uniform effect of guarantee material roasting.
Compared with the prior art, beneficial effects of the present invention are embodied in：
Apparatus of the present invention are simple in structure, easy to use.It is placed on during use above the saggar for filling material to be roasted,
And exhaust bottom of the tube is urged to and is contacted with saggar bottom.Apparatus of the present invention can enhance exhaust, prevent material from being burnt in saggar
During knot when being vented not smooth outside material spray, avoid causing material loss or influence the normal operation of roller-way furnace apparatus；In addition also may be used
With augmentation of heat transfer, have apparent energy saving and ensure that material roasts uniform effect.
