[0002] Lithium ore rotary kiln is an important equipment for lithium ore processing, mainly used in the calcination process of lithium ore. Lithium ore rotary kiln plays a key role in the refining and production of lithium ore, especially in the production of lithium minerals such as spodumene and lepidolite. Through the high temperature treatment of the rotary kiln, the impurities in the lithium minerals are removed, and finally high-purity lithium compounds are obtained.

[0003] Before using the common lithium ore rotary kiln on the market, the lithium ore usually needs to be fully crushed before calcination. However, the crushing of lithium ore takes a long time, and the waste rate of crushed lithium ore is high during transportation. In addition, after the lithium ore rotary kiln completes the calcination of lithium ore, it is usually difficult to quickly clean up the impurities in the lithium ore, which seriously affects the efficiency of lithium ore calcination.

[0015] Furthermore, the suction pipe is connected to the discharge pipe through the first suction machine, and the discharge pipe is connected to the air inlet end seat through the heat recovery pipe.

[0016] The present invention provides a waste residue treatment component and a lithium ore rotary kiln, which have the following beneficial effects: 1. The kiln body of the present invention can drive the driven roller to rotate during the rotation process. Since the driven roller is connected to the lower pressing block through the synchronous rod, the lower pressing block can be lifted and lowered back and forth with the rolling of the driven roller. The lower pressing block can impact the lithium ore at the bottom of the kiln body during the reciprocating lifting process. The internal structure of the lithium ore will gradually loosen under high-temperature calcination. The high-frequency impact of the lower pressing block can gradually form particles of uniform size, which can promote the formation of lithium compounds during the calcination reaction. Through this design, the lithium ore does not need to be finely crushed before being put into the kiln body, thanks to the high-temperature auxiliary and high-frequency impact of the lower pressing block. , which can make lithium ore form particles of uniform size more easily, which can avoid the complicated and time-consuming fine crushing process, which reduces the difficulty of lithium ore processing and avoids the waste of lithium ore when it is crushed too finely. The high-frequency impact combined with the rotation of the kiln body can further improve the heating uniformity of the lithium ore. In addition, the impact of the lower pressure block is driven by the rotation of the kiln body, which can avoid the need for an additional power source for impact, which can reduce the failure rate of the equipment. In addition, the design makes the lower pressure block positively correlated with the kiln body rotation speed, which allows the staff to flexibly adjust the impact frequency of the lower pressure block by adjusting the kiln body rotation speed.

[0017] 2. After the lithium ore of the present invention is calcined to form lithium compounds, the air pump works, and the outside air can enter the inside of the air inlet groove through the first air inlet of the air inlet ring seat, and the air inlet groove is connected with the calcination chamber inside the kiln body through the ventilation groove. Thanks to the repeated impact of the lower pressing block, after the lithium compounds are formed, the lithium compounds and impurities in the ore body can be effectively separated. After the outside air is connected to the calcination chamber, the first suction machine works, and the suction force can be transmitted to the inside of the second suction groove through the suction pipe and the suction seat. Because the weight of the impurities is lighter than that of the lithium compounds, and they can be formed into powder by the impact and calcination of the lower pressing block, and the influx of the outside air can make the powder impurities rise. The second suction trough can effectively clean up the raised impurities, and after the impurities are cleaned, the first suction machine at the other end of the sealing seat works, which can transmit the suction force to the first suction trough. The bottom end of the first suction trough is bent and close to the bottom end of the kiln body. After the lithium compound is formed, it will appear crystalline, and the crystalline lithium compound will be heavier than the impurities that have turned into dust. Therefore, the lithium compound will not be raised and sucked out by the second suction trough. Through this design, the first suction trough can absorb the crystallized lithium compound from the kiln body, and through the impact effect of the lower pressure block, the equipment can quickly and conveniently separate and extract the lithium compound and impurities after the lithium compound is formed, which can greatly improve the working efficiency of the equipment.

[0018] 3. The impurities and lithium compounds proposed in the present invention will be sent to the discharge pipe by the first suction machine for storage. After the impurities and lithium compounds are sent to the discharge pipe, the second suction machine will work to make the residual heat in the impurities and lithium compounds enter the heat recovery pipe, and then return to the interior of the kiln body through the air inlet end seat, the second air inlet, and the air inlet groove. The partition is made of high-temperature resistant asbestos mesh, which can prevent the impurities and lithium compounds from being sucked back into the kiln body again. Through this design, the equipment can recover the heat in the impurities and lithium compounds, which can effectively reduce the heat consumption during the subsequent calcination of lithium ore. By absorbing the heat, the heat of the impurities and lithium compounds can be effectively reduced, thereby facilitating the subsequent treatment of impurities and lithium compounds.

Through the operation of the feeder, the lithium ore to be roasted can be fed into the kiln body 3. The kiln body 3 is heated by electric heat. By energizing the kiln body 3, high temperature can be generated in the kiln body 3. At the same time, through the operation of the driving machine 5, the driving gear 6 can drive the driven gear 4 to rotate. The driven gear 4 is fixed to the kiln body 3, which allows the kiln body 3 to rotate on the inner side of the support ring seat 2. During the rotation of the kiln body 3, the lithium ore can be evenly rolled in the kiln, so that it is evenly heated. During the calcination reaction of the lithium ore, the lithium in the lithium ore will undergo a chemical reaction to form a lithium compound. In addition, during the rotation of the kiln body 3, the driven roller seat 1004 can be driven to rotate. 004 is connected with the lower pressing block 1006 through the synchronous rod 1005, so that the lower pressing block 1006 can reciprocate and rise and fall with the rolling of the driven roller 1004, and the lower pressing block 1006 can impact the lithium ore at the bottom of the kiln body 3 during the reciprocating lifting process. The internal structure of the lithium ore will gradually loosen under high-temperature calcination. The high-frequency impact of the lower pressing block 1006 can gradually form particles of uniform size, which can promote the formation of lithium compounds during the calcination reaction. Through this design, the lithium ore does not need to be finely crushed before being put into the kiln body 3. Thanks to the high-temperature auxiliary and the high-frequency impact of the lower pressing block 1006, the lithium ore can be easily formed into particles of uniform size, which can avoid the complicated and time-consuming fine crushing process, which makes the lithium The difficulty of processing the ore is reduced, and at the same time, this can avoid the waste of lithium ore when it is broken too finely, and the high-frequency impact combined with the rotation of the kiln body 3 can further improve the heating uniformity of the lithium ore. In addition, the impact of the lower pressing block 1006 is driven by the rotation of the kiln body 3, which can avoid the need to provide an additional power source for impact, which can reduce the failure rate of the equipment. In addition, this design makes the lower pressing block 1006 positively correlated with the rotation speed of the kiln body 3, which allows the staff to flexibly adjust the impact frequency of the lower pressing block 1006 by adjusting the rotation speed of the kiln body 3. After the lithium ore is calcined to form lithium compounds, the air pump 902 works, and the outside air can enter the air inlet groove 8 through the first air inlet 904 of the air inlet ring seat 901, and the air inlet groove 8 passes through the ventilation groove 70 4 is connected to the calcining chamber inside the kiln body 3. Thanks to the repeated impact of the lower pressing block 1006, after the lithium compound is formed, the lithium compound and impurities in the ore body can be effectively separated. After the external air is connected to the calcining chamber, the first suction machine 1011 works, and the suction force can be transmitted to the inside of the second suction trough 1008 through the suction pipe 1010 and the suction seat 1009. Because the weight of the impurities is lighter than that of the lithium compound, and the powder can be formed by the impact and calcination of the lower pressing block 1006, and the influx of external air can make the powder impurities rise, which makes the second suction trough 1008 effectively clean the raised impurities. After the impurity cleaning is completed, the first suction machine 1011 at the other end of the sealing seat 1002 works.The suction force can be transmitted to the first suction trough 1007. The bottom end of the first suction trough 1007 is bent and close to the bottom end of the kiln body 3. After the lithium compound is formed, it will appear crystalline, and the crystalline lithium compound will be heavier than the impurities that have turned into dust. Therefore, the lithium compound will not be lifted up and sucked out by the second suction trough 1008. Through this design, the first suction trough 1007 can absorb the crystallized lithium compound from the kiln body 3, and through the impact effect of the lower pressing block 1006, the equipment can quickly and conveniently separate and extract the lithium compound and impurities after the lithium compound is formed, which can greatly improve the working efficiency of the equipment. The extracted impurities and lithium compounds will be sent to the discharge pipe 1012 for storage by the first suction machine 1011, and the impurities and lithium compounds will be sent to the discharge pipe 1012 for storage. Afterwards, the second suction machine 1016 works, which can make the residual heat in the impurities and lithium compounds enter the heat recovery pipe 1015, and the bin channel passes through the air inlet end seat 903, the second air inlet 905, and the air inlet groove 8 to return to the inside of the kiln body 3 again. The partition 1014 is made of high-temperature resistant asbestos mesh, which can prevent the impurities and lithium compounds from being sucked back into the kiln body 3 again. Through this design, the equipment can recycle the heat in the impurities and lithium compounds, which can effectively reduce the heat consumption during the subsequent calcination of lithium ore. By absorbing the heat, the heat of impurities and lithium compounds can be effectively reduced, thereby facilitating the subsequent treatment of impurities and lithium compounds. After the impurities and lithium compounds are reduced to a lower temperature, the electric control baffle 1013 is opened, and the impurities and lithium compounds can be sent out from the inside of the discharge pipe 1012.

[0023] In summary, when the waste residue treatment component and the lithium ore rotary kiln are used, first, the feed pipe 702 can be connected with the feeder outside the equipment, and the lithium ore to be roasted can be fed into the kiln body 3 through the operation of the feeder. The kiln body 3 is heated by electric heat. By energizing the kiln body 3, a high temperature can be generated in the kiln body 3. At the same time, the driving gear 6 can drive the driven gear 4 to rotate through the operation of the driving machine 5. The driven gear 4 is fixed to the kiln body 3, so that the kiln body 3 can rotate on the inner side of the support ring seat 2. During the rotation of the kiln body 3, the lithium ore can be evenly rolled in the kiln, so that it is evenly heated. During the calcination reaction of the lithium ore, the lithium in the lithium ore will undergo a chemical reaction to form a lithium compound. Then, the kiln body 3 can drive the driven roller 1004 to rotate during the rotation process, because the driven roller 1004 is connected with the lower pressing block 1006 through the synchronous rod 1005, which enables the lower pressing block 1006 to reciprocate and rise and fall with the rolling of the driven roller 1004, and the lower pressing block 1006 can impact the lithium ore at the bottom of the kiln body 3 during the reciprocating lifting process. Under high-temperature calcination, the internal structure of the lithium ore will gradually loosen. Through the high-frequency impact of the lower pressing block 1006, the lithium ore can gradually form particles of uniform size, which can promote the formation of lithium compounds during the calcination reaction. Through this design, the lithium ore does not need to be finely crushed before being put into the kiln body 3, thanks to the high temperature auxiliary and the lower pressing block The high-frequency impact of the block 1006 can make the lithium ore form particles of uniform size more easily, which can avoid the complicated and time-consuming fine crushing process, which reduces the difficulty of processing the lithium ore and avoids the waste of lithium ore when it is too finely crushed. The high-frequency impact combined with the rotation of the kiln body 3 can further improve the heating uniformity of the lithium ore. In addition, the impact of the lower pressing block 1006 is driven by the rotation of the kiln body 3, which can avoid the need for an additional power source for impact, which can reduce the failure rate of the equipment. In addition, the design makes the lower pressing block 1006 positively correlated with the rotation speed of the kiln body 3, which allows the staff to flexibly adjust the impact frequency of the lower pressing block 1006 by adjusting the rotation speed of the kiln body 3. After the lithium ore is calcined to form lithium compounds, the air pump 902 works, and the outside air can enter the air inlet groove 8 through the first air inlet 904 of the air inlet ring seat 901, and the air inlet groove 8 is connected with the calcination chamber inside the kiln body 3 through the ventilation groove 704. Thanks to the repeated impact of the lower pressing block 1006, after the lithium compounds are formed, the lithium compounds and impurities in the ore body can be effectively separated. After the outside air is connected to the calcination chamber, the first suction machine 1011 works, and the suction force can be transmitted to the inside of the second suction groove 1008 through the suction pipe 1010 and the suction seat 1009. Because the weight of the impurities is lighter than that of the lithium compounds, and they can be formed into powder by the impact and calcination of the lower pressing block 1006, and the influx of outside air can make the powdery impurities rise. This enables the second suction groove 1008 to effectively clean up the raised impurities. After the impurities are cleaned, the first suction machine 1011 at the other end of the sealing seat 1002 works, and the suction force can be transmitted to the first suction groove 1007. The bottom end of the first suction groove 1007 is bent and close to the bottom end of the kiln body 3. After the lithium compound is formed, it will appear crystalline, and the crystalline lithium compound will be heavier than the impurities that have become dust. Therefore, the lithium compound will not be raised and sucked out by the second suction groove 1008. Through this design, the first suction groove 1007 can absorb the crystallized lithium compound from the kiln body 3, and through the impact effect of the lower pressing block 1006, the equipment can quickly and conveniently separate and extract the lithium compound and impurities after the lithium compound is formed, which can greatly improve the working efficiency of the equipment. Finally, the impurities and lithium compounds that are taken out will be sent to the discharge pipe 1012 for storage by the first suction machine 1011. After the impurities and lithium compounds are sent to the discharge pipe 1012, the second suction machine 1016 works, which can make the residual heat in the impurities and lithium compounds enter the heat recovery pipe 1015, and return to the inside of the kiln body 3 again through the air inlet end seat 903, the second air inlet 905, and the air inlet groove 8. The partition 1014 is made of high-temperature resistant asbestos mesh, which can prevent the impurities and lithium compounds from being sucked back into the kiln body 3 again. Through this design, the equipment can recover the heat in the impurities and lithium compounds, which can effectively reduce the heat consumption during the subsequent calcination of lithium ore. By absorbing the heat, the heat of impurities and lithium compounds can be effectively reduced, thereby facilitating the subsequent treatment of impurities and lithium compounds. After the impurities and lithium compounds drop to a lower temperature, the electric control baffle 1013 opens, and the impurities and lithium compounds can be sent out from the discharge pipe 1012.
