Description

Technical Field

[0001] This utility model relates to the field of spodumene fine roasted material conveying technology, specifically to a spodumene fine roasted material spiral conveying device. Background Technology

[0002] Spodumene fine roasted feedstock refers to spodumene material that has undergone high-temperature roasting and pulverization. Its particle size is typically less than 0.074 mm (approximately 200 mesh). This material exhibits good reactivity in subsequent lithium extraction processes, reacting with acids or other chemical reagents to extract lithium. Spodumene concentrate is the raw material for preparing fine roasted feedstock, and it usually requires screening and drying to remove impurities and moisture. Fine roasted feedstock is a key intermediate product in lithium extraction processes, primarily used in the sulfuric acid process. Through acid roasting, the lithium in the fine roasted feedstock dissolves in water as lithium sulfate, thus achieving lithium extraction. The small particle size and high reactivity of the fine roasted feedstock improve the lithium leaching rate and extraction efficiency.

[0003] Currently, screw conveyors are typically used to transport spodumene fine roasted material to storage silos. However, traditional screw conveyors are difficult to clean, affecting their conveying efficiency. Additionally, the height of the discharge end of the conveying pipe cannot be adjusted, resulting in poor compatibility with the inlet of the storage silo.

[0004] Therefore, a screw conveyor for fine spodumene roasted material is proposed to solve the above problems. Utility Model Content

However, traditional screw conveyors are inconvenient to clean, affecting conveying efficiency. In addition, the height of the material discharge end of the conveying pipe cannot be adjusted, resulting in poor compatibility with the inlet of the storage bin.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Please see Figure 1-4 This embodiment provides a screw conveyor for spodumene fine roasted material, including a mounting frame 1. An angle adjustment mechanism 2 and a conveying cylinder 3 for conveying spodumene fine roasted material are installed inside the mounting frame 1. The angle adjustment mechanism 2 can adjust the angle of the conveying cylinder 3. The conveying cylinder 3 is equipped with a detachable inner wall cylinder 4 and a screw rod 36 for conveying spodumene fine roasted material. The screw rod 36 is located inside the inner wall cylinder 4 and rotates inside the inner wall cylinder 4 to convey material. The inner wall cylinder 4 is easy to disassemble, which facilitates cleaning of the contact surface between the device and the material. At the same time, the angle adjustment mechanism 2 can adjust the height of the discharge end of the conveying cylinder 3, so as to adapt to the inlet height of different storage bins.

[0027] In this embodiment, as Figure 1As shown, a motor 21 is installed on the angle adjustment mechanism 2. The motor 21 is installed at one end of the bottom inner side of the mounting bracket 1. A lead screw 22 is installed on the output end of the motor 21. One end of the lead screw 22 is rotatably connected to the other end of the inner side of the mounting bracket 1, so that the motor 21 can drive the lead screw 22 to rotate in place.

[0028] In this embodiment, as Figure 2 As shown, a movable block 23 is threadedly connected to the outer ring surface of the lead screw 22. A pull rod 24 is rotatably connected to both sides of the movable block 23. A rotating block 25 is rotatably connected to one end of each pull rod 24. The two rotating blocks 25 are respectively installed on one side of one end of the conveying cylinder 3. The movable block 23 is limited by the pull rod 24 and the rotating block 25. When the lead screw 22 rotates, the movable block 23 moves on the lead screw 22 under the action of the thread.

[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, rotating shafts 33 are installed on both sides of one end of the conveying cylinder 3. One end of the conveying cylinder 3 is rotatably installed inside the mounting frame 1 through the two rotating shafts 33. Since one end of the conveying cylinder 3 is already rotatably installed, when the other end is pulled by the pull rod 24, one end of the conveying cylinder 3 will rotate, thereby adjusting the height of the discharge port.

[0030] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, a limit cover 34 is symmetrically installed at the top and bottom of one end of the conveying cylinder 3. The inside of the limit cover 34 is connected to the inside of the conveying cylinder 3. Bolts are symmetrically installed at both ends of the outer surface of the limit cover 34. Electric push rods 35 are symmetrically installed at the top and bottom of the conveying cylinder 3 near the limit cover 34. A limit plate 41 matching the inner size of the limit cover 34 is installed at the top and bottom of one end of the inner wall cylinder 4. Threaded holes 42 matching the size of the bolts on the limit cover 34 are opened at both ends of the outer surface of the limit plate 41. The inner wall cylinder 4 can be inserted into the gap between the inside of the conveying cylinder 3 and the screw rod 36. One end of the electric push rod 35 extends into the inside of the limit cover 34 and fits against one end of the limit plate 41. When it is necessary to disassemble the inner wall cylinder 4, simply unscrew the bolts and push the limit plate 41 with the electric push rod 35 to move it, so that one end of the inner wall cylinder 4 extends out of the conveying cylinder 3. At this time, it is convenient to clean the inner wall cylinder 4, ensuring the conveying efficiency of the equipment.

[0031] Working principle: When using this lithium spodumene fine roasted material screw conveyor, the motor 21 first drives the lead screw 22 to rotate, causing the moving block 23 to move on the lead screw 22. At this time, the moving block 23 pulls the pull rod 24 to rotate. During the rotation of the pull rod 24, it applies force to the conveying cylinder 3 through the rotating block 25. Since one end of the conveying cylinder 3 is rotatably connected by the rotating shaft 33, when the pull rod 24 pulls the other end, it will cause one end of the conveying cylinder 3 to rotate, thereby adjusting the height of the discharge port to adapt to the inlet height of different storage bins. When it is necessary to disassemble the inner wall cylinder 4, simply unscrew the bolts and push the limit slide plate 41 to move through the electric push rod 35, so that one end of the inner wall cylinder 4 extends out of the conveying cylinder 3. At this time, it is convenient to clean the inner wall cylinder 4, ensuring the conveying efficiency of the equipment.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
