Description

Technical Field

[0001] This utility model relates to the field of conveying system technology, specifically an alumina conveying system. Background Technology

[0002] In the process of electrolytic aluminum, fluorinated alumina needs to be added to the electrolytic cell to promote the electrolytic reaction. Fluorinated alumina can be transported using an ultra-dense phase conveying system. However, some fluorinated alumina materials are of poor quality, with small particles and sticky material, which can easily cause material blockage when transported using an ultra-dense phase conveying system. Utility Model Content

[0003] The main objective of this invention is to provide an alumina conveying system to solve the problem of material blockage that easily occurs when fluorine-loaded alumina is conveyed using an ultra-dense phase conveying system in the prior art.

[0004] To achieve the above objectives, this utility model provides an alumina conveying system, including an electrolytic cell, a fluorinated alumina silo, and a dense phase conveying chute for conveying materials to the electrolytic cell. The bottom of the fluorinated alumina silo is connected to the end of the dense phase conveying chute. A fresh alumina silo is provided on one side of the fluorinated alumina silo, and the bottom of the fresh alumina silo is connected to the dense phase conveying chute. A valve is provided at the bottom of both the fluorinated alumina silo and the fresh alumina silo.

[0005] Furthermore, both the fluorinated alumina silo and the fresh alumina silo are equipped with impeller feeders at the bottom, located below the valve.

[0006] Furthermore, a flow meter is installed on the ultra-dense phase conveying chute.

[0007] Furthermore, it also includes a second fresh alumina silo, which is connected to one end of a first conveying chute. The other end of the first conveying chute is connected to one end of a second conveying chute, and the other end of the second conveying chute is connected to a flue gas desulfurization and dust removal device. The flue gas desulfurization and dust removal device is connected to a fluorine-loaded alumina silo via a third conveying chute.

[0008] Furthermore, the other end of the first conveying chute is connected to one end of the fourth conveying chute, and the other end of the fourth conveying chute is connected to a fresh alumina silo; both the second and fourth conveying chutes are equipped with valves.

[0009] This invention, by setting up a fresh alumina hopper, can incorporate fresh alumina into the fluorinated alumina when the quality of the fluorinated alumina material is poor, thereby avoiding blockage inside the ultra-dense phase conveying chute and affecting the conveying of the fluorinated alumina.

[0010] This utility model, by setting a fourth conveying chute, can be connected to the existing chute that supplies material to the flue gas desulfurization and dust removal device, making full use of the existing chute to convey material to the fresh alumina silo. Attached Figure Description

[0016] like Figures 1 to 2 As shown, according to an embodiment of the present invention, an alumina conveying system is provided, including an electrolytic cell 1, a fluorinated alumina silo 2, and a dense phase conveying chute 3 for conveying materials to the electrolytic cell 1. The bottom of the fluorinated alumina silo 2 is connected to the end of the dense phase conveying chute 3. A fresh alumina silo 4 is provided on one side of the fluorinated alumina silo 2, and the bottom of the fresh alumina silo 4 is connected to the dense phase conveying chute 3. Valves 5 are provided at the bottom of both the fluorinated alumina silo 2 and the fresh alumina silo 4.

[0017] Both the fluorinated alumina silo 2 and the fresh alumina silo 4 are equipped with impeller feeders 6 located at the bottom below valve 5.

[0018] A flow meter 14 is installed on the ultra-dense phase conveying chute 3; the flow meter 14 determines the flow of materials in the ultra-dense phase conveying chute 3.

[0019] By setting up a fresh alumina silo 4, when the quality of the fluorinated alumina material is poor and the material flow rate in the ultra-dense phase conveying chute 3 is too slow, the impeller feeder 6 and valve 5 at the bottom of the fresh alumina silo 4 can be opened to add fresh alumina into the fluorinated alumina, thereby avoiding blockage inside the ultra-dense phase conveying chute 3 and affecting the conveying of the fluorinated alumina.

[0020] In some embodiments, a second fresh alumina silo 7 is also included. The second fresh alumina silo 7 is connected to one end of a first conveying chute 8. The other end of the first conveying chute 8 is connected to one end of a second conveying chute 9. The other end of the second conveying chute 9 is connected to a flue gas desulfurization and dust removal device 10. The flue gas desulfurization and dust removal device 10 is connected to a fluorine-loaded alumina silo 2 via a third conveying chute 11.

[0021] In some embodiments, the other end of the first conveying chute 8 is also connected to one end of the fourth conveying chute 12, and the other end of the fourth conveying chute 12 is connected to the fresh alumina silo 4; both the second conveying chute 9 and the fourth conveying chute 12 are equipped with valves 13; valves 13 can control the flow direction of materials as needed.

[0022] By setting up a fourth conveying chute 12, it can be connected to the existing chute that supplies material to the flue gas desulfurization and dust removal device 10, making full use of the existing chute to convey material to the fresh alumina silo 4.
