[0002] my country's salt lake lithium resources are mainly concentrated in the Qinghai-Tibet region. The environment and ecology in the western region are fragile and have high requirements for environmental protection. Therefore, the large-scale development of salt fields will be restricted in the process of lithium extraction from salt lakes. However, brine concentration is an important link in the salt lake lithium extraction process. The stable supply of concentrated brine is the cornerstone of salt lake lithium extraction. The existing brine concentration method usually adopts the conventional salt drying method, that is, by building a salt drying pool (salt flat), using natural wind and sun to evaporate nearly 90% of the water in the pool, and then realizing the concentration of brine. It relies on natural evaporation under sunlight, has a long production cycle, low efficiency, and is heavily dependent on the weather. The output of brine is difficult to control and cannot meet production needs. Therefore, a salt lake brine concentration device is proposed to address the above problems. Utility Model Content

Based on the specific embodiments of the present invention, all other specific embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] Example 1

[0019] like Figure 1-2 As shown, a salt lake brine concentrating device comprises a brine pool 1, the right end of the brine pool 1 is connected to a water pump 2, the top of the brine pool 1 is fixedly connected to a controller 22, the inner right end of the brine pool 1 is fixedly connected to a filter screen 3, the top of the water pump 2 is connected to a water pipe 4, the outer side of the water pipe 4 is fixedly connected to a concentration cover 5, the inner side of the concentration cover 5 is rotatably connected to a copper tube 7, the inner bottom end of the copper tube 7 is provided with an electric heating rod 6 fixedly connected to the concentration cover 5, the other end of the water pipe 4 is connected to a water outlet cover 8 fixedly connected to the concentration cover 5, and the bottom end of the water outlet cover 8 is provided with evenly distributed through holes, the water outlet cover 8 is rotatably connected to the copper tube 7, the bottom end of the right side of the concentration cover 5 is connected to a liquid outlet pipe 10, and the top right side of the concentration cover 5 is fixedly connected to a dual-axis motor 11.

[0020] Example 2

[0021] like Figure 2 As shown, in order to solve the problem of large friction generated by the rotation of the copper tube 7, a bearing 9 is fixedly connected to the top end of the outer side of the copper tube 7, and the bearing 9 is fixedly connected to the concentration cover 5. By connecting the copper tube 7 to the concentration cover 5 through the bearing 9, large friction is avoided when the copper tube 7 rotates.

[0022] Example 3

[0023] like Figure 1-2As shown, in order to solve the problem of poor discharge effect of water vapor evaporated from the brine, a bellows 12 fixedly connected to the concentration hood 5 is fixedly connected to the outside of the dual-axis motor 11, and an impeller 13 is fixedly connected to the right main shaft end of the dual-axis motor 11. The bottom end of the bellows 12 is connected to a fixed pipe 14 connected to the concentration hood 5, and the right end of the bellows 12 is connected to an air outlet pipe 15. In the process of evaporating and concentrating the brine, the impeller 13 is driven to rotate by the dual-axis motor 11, and the water vapor in the concentration hood 5 is further drawn out through the fixed pipe 14, so that the discharge effect of water vapor evaporated from the brine is better.

[0024] Example 4

[0025] like Figure 2 As shown, in order to solve the problem of inconvenience in cleaning the brine crystals attached to the outside of the copper tube 7, the left main shaft end of the dual-axis motor 11 is fixedly connected with a driving bevel gear 16, and the outer side of the driving bevel gear 16 is meshedly connected with a driven bevel gear 17 fixedly connected to the copper tube 7, and the right bottom end of the copper tube 7 is slidably connected with a scraper 18. The dual-axis motor 11 drives the driving bevel gear 16 to mesh with the driven bevel gear 17, and further enables the scraper 18 to scrape the rotating copper tube 7, which facilitates the cleaning of the brine crystals attached to the outside of the copper tube 7.

[0026] Example 5

[0027] like Figure 2 As shown, in order to solve the problem of poor cleaning effect of brine crystals on the outside of the copper tube 7, the right end of the scraper 18 is fixedly connected to a fixed rod 19, and the outside of the fixed rod 19 is slidably connected to a sleeve rod 20 fixedly connected to the concentration cover 5, and the inside of the sleeve rod 20 is fixedly connected to a spring 21, and the other end of the spring 21 is fixedly connected to the fixed rod 19. By making the scraper 18 contact with the copper tube 7 under the elastic force of the spring 21 on the fixed rod 19, the cleaning effect of the brine crystals on the outside of the tube 7 is better.

[0028] In this embodiment, when the brine is concentrated by the device, the device is started by the controller 22. At this time, the water pump 2 will draw the brine in the brine pool 1 and filter it through the filter 3. Then, it will be sprayed to the surrounding of the copper tube 7 through the water pipe 4 and the through-hole at the bottom of the water outlet cover 8. Then, the copper tube 7 is heated by the electric heating rod 6. When the brine flows down along the outer wall of the heated copper tube 7, the brine can be continuously evaporated and concentrated. The concentrated brine will finally be discharged through the liquid outlet pipe 10. Because the dual-axis motor 11 will also drive the impeller 13 to rotate at this time, the water vapor generated during the concentration process will enter the bellows 12 through the fixed pipe 14 under the traction of the impeller 13, and then be discharged through the air outlet pipe 15. During the concentration process, some crystals may precipitate out of the brine and adhere to the outside of the copper tube 7. At this time, the left end main shaft of the dual-axis motor 11 drives the active bevel gear 16 to engage the driven bevel gear 17, further driving the copper tube 7 to rotate. When the scraper 18 scrapes the outer wall of the rotating copper tube 7 under the elastic force of the spring 21 on the fixed rod 19, the brine crystals attached to the outside of the copper tube 7 can be scraped off, thereby ensuring the evaporation and concentration effect of the brine. At this time, in conjunction with the evaporation of the brine in the brine pool 1 by the sun, when the brine is concentrated, the production cycle is shortened, the production efficiency is improved, the dependence on the weather is reduced, and the control of the brine output is convenient, thereby meeting the production needs well.
