An exhaust port 12 is also provided on the top. The device can heat and evaporate the lithium carbonate solution. The evaporated hot gas is connected to the exhaust filter device through the exhaust port 12. The exhaust filter device adopts the existing technology and is not described in detail. After the lithium carbonate solution is evaporated, the hydraulic lifting column 3 lifts the sealing cover 4. At this time, there are residual crystals on the stirring column 53 of the stirring mechanism 5. The pulling plate 9 is pushed inward. After the stirring column is cooled, the scraping hole 11 on the scraper plate 10 corresponds to the stirring column 53 of the stirring mechanism 5. The hydraulic lifting column 3 is started to descend, and the stirring column 53 slides in the scraping hole 11, so that the crystals on the surface of the stirring column 53 are scraped onto the scraper plate 10, which is convenient for subsequent crystal collection.

[0030] The stirring mechanism 5 includes a driving motor 51, which is arranged on the top of the sealing cover 4. The bottom of the driving motor 51 is connected to a rotating shaft, and the rotating shaft is connected to a rotating disk 52. The bottom of the rotating disk 52 is connected to multiple stirring columns 53. The scraping holes 11 are matched and connected with the stirring columns 53. The stirring columns 53 can be heated stirring columns 53, which have a heating effect on the internal solution while stirring. When the stirring mechanism 5 finishes stirring and the internal evaporation reaction ends, the hydraulic lifting column 3 lifts the stirring column 53 at the bottom, and then the scraping disk 10 moves inward and its scraping holes 11 are aligned with each stirring column 53. The hydraulic lifting column 3 is lifted to perform the scraping operation.

[0031] A heating base 21 is provided at the bottom of the evaporator box 1, and the bottom of the heating base 21 is connected to a moving wheel 22.

The limit hole 92 is detachably connected to a limit screw 93. When the pull-out plate 9 slides inward to prepare for scraping, the limit plate 91 abuts against the sliding groove 8. At this time, the position of the scraper plate 10 is just located at the bottom of the stirring column 53. The limit plate 91 facilitates the pull-out plate 9 to reach a preset position.

One end of the rotating screw 34 is connected to a positioning block 35 with a bearing, and the other end is connected to a first motor 36. The first motor 36 is arranged on one side of the evaporation box 1. After the lithium carbonate solution evaporates, some crystals will adhere to the inner wall of the evaporation box 1. Therefore, a sliding scraper 32 is arranged. When the rotating screw 34 rotates, it will drive the sliding scraper 32 to scrape out the crystals on the inner wall, so as to facilitate the removal of the internal crystals.

[0034] The evaporation box 1 has a discharge port 23 on its side, which is detachably connected to a sealing door 24 via screws. When the internal solution evaporates, the sealing door 24 is opened to take out the crystals inside. The crystals scraped out by the sliding scraper 32 are also taken out from this door.

[0035] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model.
