When the high-nickel material passes through the heating section of the roller kiln, the strong alkaline lithium source is easy to volatilize, and the high-nickel material has higher evaporated moisture content, so that a large amount of strong alkaline water vapor is generated at the heating section of the roller kiln, and the roller kiln is damaged due to corrosion of the strong alkaline water vapor. Because the roller kiln is of an integrated structure, a great deal of time is required to be spent when the roller kiln is maintained and replaced.

Referring to fig. 1 to 3, a lithium battery cathode material sintering apparatus 100 according to an embodiment of the present utility model will now be described.
Referring to fig. 2, the X-axis, Y-axis, and Z-axis in the drawing are the length direction of the sintering furnace body 20, the width direction of the sintering furnace body 20, and the up-down direction, respectively.
Referring to fig. 1 and 2, a lithium battery cathode material sintering device 100 provided by the utility model comprises a heating furnace body 10, a sintering furnace body 20 and a conveying mechanism 30, wherein the heating furnace body 10 is provided with a first material channel 11 for materials to pass through, the heating furnace body 10 is used for heating the materials, the sintering furnace body 20 is provided with a second material channel 21 for materials to pass through, the sintering furnace body 20 is used for sintering the materials, the heating furnace body 10 is provided with at least part of the conveying mechanism 30, the sintering furnace body 20 is provided with at least part of the conveying mechanism 30, and the conveying mechanism 30 is used for conveying the materials from the first material channel 11 into the second material channel 21, wherein the heating furnace body 10 and the sintering furnace body 20 are arranged separately.
In operation, the heating furnace body 10 heats and dries the material in the first material channel 11, and since the heating furnace body 10 has at least a part of the conveying mechanism 30, the material in the first material channel 11 can approach the second material channel 21 of the sintering furnace body 20 under the action of the conveying mechanism 30, and finally enter the second material channel 21. After the material completes the sintering operation in the second material passage 21, the conveying mechanism 30 on the sintering furnace body 20 conveys the material out of the second material passage 21. The temperature rising furnace body 10 and the sintering furnace body 20 are arranged separately, which is equivalent to independently splitting the temperature rising section in the traditional integrated sintering device. In this way, on one hand, the amount of the strong alkaline steam entering the sintering furnace body 20 is reduced, which is beneficial to prolonging the service life of the sintering furnace body 20, and on the other hand, when the strong alkaline steam corrodes the heating furnace body 10 for a long time to cause the damage of the heating furnace body 10, the worker can directly replace the heating furnace body 10 or repair the heating furnace body 10 without operating the sintering furnace body 20. The maintenance efficiency and the replacement efficiency of the lithium battery anode material sintering device 100 are greatly improved, and the maintenance and replacement cost of the lithium battery anode material sintering device 100 is reduced. In addition, because the temperature-rising furnace body 10 is separately arranged, the temperature-rising furnace body 10 can be more frequently maintained and replaced by a worker, and the maintenance and replacement period of the lithium battery anode material sintering device 100 is effectively shortened.
It will be appreciated that the furnace body 10 may be a roller kiln or rotary kiln. In this embodiment, the heating furnace 10 is a rotary kiln, and the rotary kiln drives the material located in the first material channel 11 to approach the sintering furnace 20 when rotating. Compared with a roller kiln, the rotary kiln can dry materials more uniformly. It will be appreciated that the rotary kiln comprises a barrel and a turning mechanism for driving the barrel in a turning motion, the barrel being hollow in the middle to form the first material passageway 11, the barrel and turning mechanism being part of the conveying mechanism 30 of the present utility model. Roller kilns and rotary kilns are both of the prior art and are well established, and therefore will not be described in detail herein.
In another embodiment of the present utility model, the heating furnace 10 is made of a strong alkali corrosion resistant material. Specifically, the strong alkali corrosion resistant material may be silicon carbide, mullite, aluminum oxide, or a corrosion resistant metal alloy material, or the like.

Specifically, the second component 13 is an assembly structure of one part or more than two parts in the rotary kiln, which are in contact with materials or in contact with strong alkaline water vapor, while the first component 12 is an assembly structure of one part or more than two parts in the rotary kiln, which are not in contact with materials or in contact with strong alkaline water vapor. In operation, the material evaporates in the first material passage 11 of the second component 13 to form water vapor, which is a source of lithium that is volatile and highly alkaline, so that the second component 13 contains a large amount of highly alkaline water vapor that can corrode the second component 13 and cause damage to the second component 13. The second component 13 is made of the strong alkali corrosion resistant material, so that the service lives of the second component 13 and the rotary kiln can be effectively prolonged. By connecting the first component 12 and the second component 13 in a detachable connection manner, the second component 13 can be replaced independently, so that the cost is saved and the maintenance and replacement efficiency is improved. In addition, the maintenance efficiency and replacement efficiency of the second module 13 can be shortened.

The air inlet channel can be a cavity communicated with the first component 12 or can be a first material channel 11 communicated with the second component 13. In this embodiment, the air intake passage communicates with the first material passage 11. In operation, the heating system heats up, thereby producing hot air which enters the waste heat utilization conduit 40 through the exhaust passage and ultimately into the first material passage 11 through the inlet passage on the rotary kiln. In this way, hot air generated in the sintering furnace body 20 can enter the first material channel 11 of the rotary kiln to assist in heating the second component 13. The energy consumption of the rotary kiln can be effectively reduced, and the service life of a heating component in the rotary kiln can be prolonged.

After a period of discharge, the valve of the discharge mechanism 50 is closed, effecting filling of the first sagger 70. Subsequently, the second sagger 70 approaches the second conveying unit 312 under the action of the first conveying unit 311, and when the second sagger 70 approaches the second conveying unit 312, the first sagger 70 is pushed to move in the extending direction of the second conveying unit 312 by the action of the second conveying unit 312, and finally, the first sagger 70 and the second sagger 70 are respectively located on two placement areas of the second conveying unit 312.
