DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: See Figures 1 to 5 According to an embodiment of the utility model, a technical solution is provided: a stirring reactor for the reaction of lithium mica concentrate and calcium hydroxide, comprising a liquid storage container 1, wherein the top of the liquid storage container 1 is provided with two chutes 2 and a discharge port 3; a stirring structure 4, arranged in the liquid storage container 1, suitable for stirring the liquid in the liquid storage container 1; a foam scraping assembly, comprising a slide rod 5 slidably connected in the chute 2, at least one end of the slide rod 5 protrudes from the chute 2, and the end thereof protruding from the chute 2 is threadedly connected to a threaded rod 6, one end of the threaded rod 6 is rotatably connected to the liquid storage container 1, and the other end is fixed to the output end of a rotating motor 7, and the rotating motor 7 is fixed to the outer wall of the liquid storage container 1, two connecting blocks 8 are arranged at the bottom of the slide rod 5, a rotating rod 9 is rotatably connected between the two connecting blocks 8, and a foam scraper 10 rotatably connected to the rotating rod 9 is arranged on the rotating rod 9.

[0024] The stirring reactor for the reaction of lithium mica concentrate and calcium hydroxide is adopted. A mixed solution of lithium mica ore and water is added into a liquid storage container 1, and lime water is added into the liquid storage container 1. Then, the lime water and the mixed solution of lithium mica ore and water are mixed by a stirring structure 4. After mixing and fully reacting, the stirring structure 4 stops running. The lithium mica floats on the surface due to its buoyancy. Then, the threaded rod 6 is driven to rotate by a rotating motor 7 in a forward and reverse direction, so that a sliding rod 5 threadably connected with the threaded rod 6 drives a froth scraper 10 to move back and forth in a chute 2, and the lithium mica floating on the surface is scraped out along a discharge port 3. The device can collect the lithium mica after the stirring is completed, and solves the problem that the mixed solution of the lithium mica ore and the lime water needs to be taken out after the stirring is completed in the traditional device before the subsequent flotation work can be carried out, resulting in the need to use multiple devices for flotation.

[0025] In this embodiment, the foam scraping assembly includes a stirring shaft 41, a servo motor 42 and a plurality of blades 43. The stirring shaft 41 is rotatably connected to the liquid storage container 1, one end of which protrudes from the liquid storage container 1 and is fixed to the output end of the servo motor 42. The servo motor 42 is fixed to the outer wall of the liquid storage container 1. The plurality of blades 43 are distributed on the stirring shaft 41 at intervals and are fixed to the stirring shaft 41. The stirring shaft 41 is driven to rotate by the servo motor 42. During the rotation, the stirring shaft 41 drives the blades 43 fixed thereto to stir the mixed solution in the liquid storage container 1.

[0026] In this embodiment, a collecting piece 11 is obliquely arranged at the discharge port 3, the higher end of the collecting piece 11 is fixed to the outer wall of the liquid storage container 1, and the lower end of the collecting piece 11 is provided with a mud storage container 12. By arranging the collecting piece 11 and the mud storage container 12, the lithium mica scraped out by the foam scraper 10 along the discharge port 3 can be collected.

[0027] In this embodiment, a fixing frame 13 is also included, and the fixing frame 13 is fixed to the collecting piece 11 and the outer wall of the liquid storage container 1. By setting the fixing frame 13, the stability of the collecting piece 11 can be increased, and the collecting piece 11 can be prevented from falling off from the outer wall of the liquid storage container 1 due to vibration or collision.

[0028] In this embodiment, a plurality of spray heads 14 are provided on the inner side of the collecting member 11, and the spray heads 14 are connected to a water tank 16 through a pipe 15. A pressure pump 17 is provided on one side of the water tank 16. By arranging a plurality of spray heads 14 in the collecting member 11, it is prevented that when the lithium mica slides downward in the collecting member 11, the lithium mica is prevented from drying and agglomerating in the collecting member 11 due to water evaporation, thereby affecting the collection efficiency. The spray heads 14 can also clean the inner side of the collecting member 11.

[0029] In this embodiment, a slag collecting drawer 18 is provided at the bottom of the liquid storage container 1, and a slag discharge port 19 for sliding connection of the slag collecting drawer 18 is opened at the bottom of the liquid storage container 1, and a liquid discharge port 20 is also provided above the slag discharge port 19, and is covered by a lid 21. By providing the slag collecting drawer 18, when the mixed solution in the liquid storage container 1 needs to be drained, most of the impurities such as potassium, sodium and calcium are easily accumulated at the bottom of the liquid storage container 1 and are difficult to clean, because there is only 1-2% lithium in the lithium mica ore, and most of the impurities such as potassium, sodium and calcium are easily accumulated at the bottom of the liquid storage container 1 and are difficult to clean, and thus the provision of the slag collecting drawer 18 can effectively collect and remove the impurities.

[0030] Working principle: The mixed solution of lithium mica ore and water is added into the liquid storage container 1, and lime water is added into the liquid storage container 1, and then the stirring shaft 41 is driven to rotate by the servo motor 42. The stirring shaft 41 drives the blades 43 fixed thereto to stir the mixed solution in the liquid storage container 1 during the rotation process. After mixing and fully reacting, the lithium mica will float on the surface due to its buoyancy, and most of the impurities will settle in the slag collection drawer 18 at the bottom of the liquid storage container 1. At this time, the threaded rod 6 is driven to rotate by the rotating motor 7 in the forward and reverse directions, so that the sliding rod 5 threadedly connected to the threaded rod 6 drives the foam scraper 10 to move back and forth in the chute 2, and the lithium mica floating on the surface is moved along the chute 2. The discharge port 3 is scraped out, and the lithium mica scraped out by the foam scraper 10 along the discharge port 3 is collected into the mud storage container 12 through the collecting piece 11. In this collection process, the pressure pump 17 transports the water in the water tank 16 along the pipeline 15 to multiple spray heads 14, and the water is sprayed onto the inner wall of the collecting piece 11 through multiple spray heads 14 to prevent the lithium mica from drying and agglomerating and accumulating in the collecting piece 11 due to water evaporation when the lithium mica slides downward in the collecting piece 11, thereby affecting the collection efficiency. The spray heads 14 can also clean the inside of the collecting piece 11. Finally, in the process of draining the liquid, the cover 21 of the discharge port 20 is opened, the liquid is emptied, and the impurities in the slag collection drawer 18 are taken out.

[0031] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
