[0025] Please refer to the attached Figures 1-3 , a device for preventing calcium deposition in the washing water pipe 4 during the extraction of lithium from lepidolite, comprising a stirring tank 1, a feed pipe 2, a water inlet pipe 3, a washing water pipe 4, a booster pump 5, a calcium removal device, a stirring device and a support device;

[0027] The calcium removal device includes a feed pipe 6, a first valve 7, a second valve 8, a calcium removal ball 9 and a ball-catching pipe 10. The feed pipe 6 is arranged on the washing water pipe 4 near the water inlet pipe 3. Both the first valve 7 and the second valve 8 are arranged in the feed pipe 6. There is a cavity between the first valve 7 and the second valve 8. The calcium removal ball 9 is arranged in the feed pipe 6. The ball-catching pipe 10 is arranged on the washing water pipe 4 near the booster pump 5. The ball-catching pipe 10 is in a T shape, and a large mesh screen is arranged inside the ball-catching pipe 10.

[0028] With the above technical solutions, the supporting device includes a support frame 14, which is located at the bottom of the stirring tank 1 and is used to support the entire structure of the stirring tank 1. The stirring tank 1 is arranged on the supporting device and is used to store and mix the leaching solution and the leaching residue. The feed pipe 2 is arranged on the upper side of the stirring tank 1 and is used to transport the leaching residue in the form of solid particles into the stirring tank 1. Specifically, by adding 2-10% of the leaching residue to the leaching solution, the concentration of the fluid can be increased. Then, the mixed leaching residue and leaching solution flow into the stirring tank 1 through the feed pipe 2. The stirring device is arranged inside the stirring tank 1 and is used to mix the leaching residue and the leaching solution to ensure uniform distribution of the materials. Then, by the operation of the booster pump 5, the high-speed flow generated by the booster can reduce the deposition of calcium sulfate in the washing water pipe 4 and achieve the effect of preventing scale formation.

[0029] The water inlet pipe 3 is located on the washing water pipe 4 near the stirring tank 1 and is responsible for adding clean water into the stirring tank 1. The washing water pipe 4 is arranged on the lower side of the stirring tank 1 and connects the stirring tank 1 and the booster pump 5, and is used to transport the mixed slurry to the subsequent process. The calcium removal device is arranged on the feed pipe 2 and may be used to clean the washing water pipe 4 to prevent calcium scaling and blockage of the washing water pipe 4. After the washing water pipe 4 transports materials for a period of time, the calcium removal device can work to deeply clean the calcium scaling phenomenon in the washing water pipe 4 again.

[0030] In some embodiments, the stirring device includes a motor 11, a rotating shaft 12 and stirring rods 13. The motor 11 is arranged inside the stirring tank 1. The rotating shaft 12 is arranged on the output end of the motor 11. The stirring rods 13 are arranged on the rotating shaft 12, and the stirring rods 13 are located inside the stirring tank 1.

[0031] With the above technical solutions, the motor 11 is arranged inside or outside the stirring tank 1 to provide power for the stirring device. The rotating shaft 12 is connected to the output end of the motor 11 to transmit the power of the motor to the stirring rods 13. The stirring rods 13 are arranged on the rotating shaft 12 and are located inside the stirring tank 1, and stir the materials by rotating to promote the uniform mixing of the leaching residue and the leaching solution.

[0032] In some embodiments, the supporting device includes a support frame 14. The support frame 14 is arranged at the bottom of the stirring tank 1, and the support frame 14 directly supports the stirring tank 1 to ensure its stability.

[0033] In some embodiments, the mixing tank 1 and the washing water pipe 4 are connected by a flange. The flange connection between the mixing tank 1 and the washing water pipe 4 ensures the sealing and stability of the connection, and also facilitates the maintenance and replacement of the washing water pipe 4.

[0034] In some embodiments, the inner wall of the washing water pipe 4 is provided with a smooth surface, which reduces the adhesion of materials to the inner wall of the pipe and lowers the risk of scaling.

[0035] In some embodiments, the surface of the calcium removal ball 9 is provided with protrusions. The calcium removal ball 9 has specific surface protrusions, which are used to increase the physical friction and impact on the inner wall of the pipe during movement in the pipe to help remove scale.

[0036] Working principle: 2 - 10% of the leaching residue is added to the leaching solution, and then the slurry is input into the mixing tank 1 through the feed pipe 2 arranged on the upper side of the mixing tank 1. The motor 11 is controlled to drive the stirring rod 13 to work, and the materials are stirred by rotation to promote the uniform mixing of the leaching residue and the leaching solution and improve the concentration of the fluid. When discharging, the slurry is discharged through the washing water pipe 4, and the booster pump 5 works. The booster pump 5 increases the flow rate of the slurry, provides sufficient kinetic energy for the slurry, so that the slurry flows at a high speed in the washing water pipe 4, generating a strong scouring effect on the inner wall of the washing water pipe 4, reducing the deposition chance of calcium sulfate on the inner wall of the pipe. The scouring effect of the slurry helps prevent the formation of scale in the pipe, thus effectively preventing the scaling problem of the washing water pipe 4.

[0037] After the washing water pipe 4 has been transporting materials for a long time, the staff can thoroughly clean the washing water pipe 4 through the calcium removal device. Clean water is introduced through the water inlet pipe 3, and the calcium removal balls 9 are added through the ball inlet pipe 6 arranged on the washing water pipe 4 near the water inlet pipe 3. By controlling the opening and closing of these two valves, specifically, the first valve 7 is located above the second valve 8. When adding the calcium removal balls 9, the first valve 7 is controlled to open and the second valve 8 is closed. At this time, the calcium removal balls 9 enter the cavity, and then the first valve 7 is controlled to close and the second valve 8 is opened, so that the calcium removal balls 9 fall into the washing water pipe 4. This process is repeated continuously to continuously put the calcium removal balls 9 into the washing water pipe 4. The booster pump 5 works to increase the flow rate of the clean water and the calcium removal balls 9. The calcium removal balls 9 have specific surface protrusions, which are used to increase the physical friction and impact on the inner wall of the pipe during movement in the pipe to help remove scale and achieve the cleaning effect. When the calcium removal balls 9 move into the ball capture pipe 10, due to its T - shaped structure and the large - mesh sieve inside, the large - mesh sieve changes the movement direction of the calcium removal balls 9, so that the calcium removal balls 9 fall into the T - shaped ball capture pipe 10, realizing the capture and recycling of the calcium removal balls 9.

Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present utility model shall be included within the protection scope of the present utility model. In addition, the appended claims of the present utility model are intended to cover all variations and modifications that fall within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
