[0029] When it is necessary to extract lithium from lepidolite by using the device, the staff first puts the mixture of lepidolite and sulfate into the stirring barrel 10, and then starts the motor 4 and the spiral heating pipe 13 through the controller 2. When the motor 4 operates, the rotating rod 5 on the output shaft rotates, the second bevel gear 11 fixed to the left side of the rotating rod 5 also rotates, the second bevel gear 11 on the top of the stirring frame 12 is driven to rotate by the meshing force, and then drives the stirring frame 12 to rotate inside the stirring barrel 10. The rotation of the stirring frame 12 can stir the materials in the stirring barrel 10, so that the materials are mixed more uniformly, and then ensure that the leaching reaction can be carried out efficiently and uniformly.
[0030] During the roasting process, the mixing and reaction of the materials require certain temperature conditions. The staff can easily adjust the heating temperature by controlling the spiral heating pipe 13 through the controller 2, so as to ensure that the materials are in a suitable temperature range during the stirring process, thereby promoting the mixing reaction of lepidolite and sulfate, and improving the roasting efficiency and leaching effect.

[0035] When it is necessary to filter the material in the hopper 9, the staff needs to connect the water inlet end of the water pump 15 to the leaching liquid (water or dilute sulfuric acid) first, then start the water pump 15 by operating the controller 2, so as to draw water from the water source and transport it to the spray head 17 through the water pipe 16, and the water is sprayed out of the spray head 17, the water sprayed out of the spray head 17 on the left top of the water pipe 16 can wash the material residues in the stirring barrel 10 and flush them into the hopper 9, which can effectively make full use of the material and reduce waste, and the water sprayed out of the spray head 17 on the left lower part is responsible for washing the material in the hopper 9, during the leaching process, lithium sulfate is dissolved in water to form a lithium sulfate solution, and other insoluble impurities remain in the leaching residue.
[0036] When the motor 4 drives the rotating rod 5 to rotate, the first bevel gear 6 on the right part of the rotating rod 5 drives the first bevel gear 6 on the top of the connecting rod 7 to rotate, the rotation of the rotating rod 5 can drive the connecting rod 7 to rotate, and then the connecting rod 7 drives the gear ring 8 to rotate, the rotation of the gear ring 8 drives the hopper 9 to rotate through the meshing with the internal groove of the hopper 9, since the hopper 9 is internally provided with the mixed material after stirring, the rotation of the hopper 9 helps the material to better contact with the leaching liquid during the leaching process, the rotation of the hopper 9 can accelerate the solid-liquid separation by centrifugal force, reduce the filtration time, and improve the recovery rate of lithium in the leaching liquid, and the lithium-containing leaching liquid gradually enters the collection frame 18 inside the box body 1 through the opening at the bottom of the hopper 9, so as to realize the filtration and leaching process of the material.

[0039] When the filtering is completed, the staff can control the controller 2 to close the electrical elements of the device and reset the pull-off baffle 14.
[0040] When the staff needs to clean the device, the staff first wears gloves, then rotates the door at the lower side of the front of the box body 1 to open, then manually takes out the collecting frame 18 containing the lithium-containing leaching liquid, then counterclockwise rotates the annular handle outside the funnel 9 to take down the funnel 9, then processes the leaching residue, and after the processing is completed, the funnel 9 is reset.
[0041] Then, the water inlet end of the water pump 15 is connected to a cleaning liquid (such as water or a special cleaning solution), the staff needs to control the controller 2 to start the water pump 15, the water pipe 16 fixedly connected to the top water outlet end of the water pump 15 draws the liquid and transports it to the spray head 17 fixedly connected to the top left side and the lower left side of the water pipe 16, the spray head 17 then sprays the cleaning liquid to clean the parts (such as the inside of the stirring barrel 10, the funnel 9, etc.) that need to be cleaned in the device, so as to keep the inside of the device clean and prevent material residues from affecting the next operation.
[0042] Although the embodiments of the utility model have been shown and described, it can be understood by those of ordinary skill in the art that changes can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
