Description

Technical Field

[0001] This utility model relates to the field of lithium alcohol production technology, and in particular to equipment for producing lithium alcohol. Background Technology

[0002] Currently, the demand for organic lithium salts such as lithium methoxide, lithium tert-butoxide, and lithium isopropoxide is constantly increasing in the pharmaceutical industry as their applications expand. The production methods for these organic lithium salts typically involve reacting metallic lithium with the corresponding alcohol, followed by separation and drying. Alternatively, the product can be obtained directly through drying. Since most alcohols are volatile, flammable, and explosive, and the resulting lithium salts decompose upon contact with water, the production process requires stringent operating conditions. Therefore, the equipment shown in the diagram was designed to improve operating conditions, enhance process safety, reduce energy consumption, shorten the drying process, and allow for the recycling of the separated alcohols. The production of lithium alcohols requires specific preparation equipment.

[0003] During the installation and use of current production equipment by users, the following defects have been gradually discovered: (1) Most traditional production equipment does not have a stirring mechanism. The lithium metal accumulates at the bottom of the reaction tank and cannot fully contact the alcohol solution. This not only increases the reaction time and reduces the working efficiency, but also causes the lithium metal to react incompletely, wasting a lot of resources and increasing the cost. (2) Traditional preparation equipment does not have a cooling mechanism. After obtaining the lithium alcohol solution, it needs to be distilled and crystallized. However, most of the crystallization is done by natural cooling, which requires a lot of waiting time and reduces work efficiency. Utility Model Content

This not only increases the reaction time and reduces the working efficiency, but also causes the metallic lithium to react incompletely, wasting a lot of resources and increasing costs.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: The equipment for producing lithium alkoxides includes a reaction vessel, with symmetrical feed channels at the top of the reaction vessel, a stirring and mixing assembly inside the reaction vessel, and a distillation and crystallization assembly at the bottom of the reaction vessel; The mixing assembly includes a main stirring shaft located inside the reaction vessel and extending beyond the top of the reaction vessel.

[0018] like Figure 1 , Figure 2 and Figure 3As shown in the figure, this embodiment provides a lithium alkoxide production device, including a reaction tank 1, a feed channel 2 symmetrically provided at the top of the reaction tank 1, a stirring and mixing component 3 provided inside the reaction tank 1, and a distillation and crystallization component 4 provided at the bottom of the reaction tank 1.

Several third stirring blades 35 are provided on the secondary stirring shaft 34, and the third stirring blades 35 are alternately arranged with the first stirring blades 32. A first driving mechanism is provided at the top of the reaction vessel 1.

[0020] The reaction vessel 1 is also equipped with a filter screen 37. The main stirring shaft 31 passes through the filter screen 37, and the second stirring blade 33 is close to the filter screen 37. The solid and liquid in the reaction vessel 1 are separated by the filter screen 37, which helps to distill and crystallize the lithium alcohol solution in the subsequent process.

[0021] like Figure 1 and Figure 3 As shown, the distillation crystallization assembly 4 includes a distillation tank 41, a heating base 42 at the bottom of the distillation tank 41, a connecting pipe 43 at the top of the distillation tank 41, and the connecting pipe 43 is connected to the reaction vessel 1.

[0023] The second heat dissipation mechanism includes a movable plate 481 with a mounting hole 482. A third motor 483 is provided on one side of the movable plate 481. The output end of the third motor 483 is connected to a second fan blade 484, which is located inside the mounting hole 482. A second drive mechanism is provided at one end of the movable plate 481. The third motor 483 drives the second fan blade 484 to rotate, thereby further cooling the distillation tank 41.

[0024] The second drive mechanism includes extension blocks 485. Two sets of extension blocks 485 are respectively located at both ends of the support plate 471. A fourth motor 486 is provided on the top of the extension blocks 485. The output end of the fourth motor 486 is connected to a lead screw 487.

The movable plate 481 drives the fan blades 484 to move up and down, which improves the cooling effect on the distillation tank 41.

[0025] In operation, the operator adds lithium metal and the corresponding alcohol solution into the reaction vessel 1 through the feed channel 2. Then, the first motor 362 is started, driving the first and second stirring blades 32 and 33 on the main stirring shaft 31 to rotate. Simultaneously, the first spur gear 363 on the main stirring shaft 31 drives the auxiliary stirring shaft 34 on the second spur gear 364 to rotate, which in turn drives the third stirring blade 35 to rotate. The first, second, and third stirring blades 32, 33, and 35 stir the raw materials inside the reaction vessel 1, preventing lithium metal from accumulating at the bottom of the vessel, increasing the contact area between the lithium metal and the alcohol solution, and accelerating the reaction. This not only reduces reaction time and improves efficiency but also ensures a more complete lithium metal reaction, saving significant resources and reducing costs. Next, the solid and liquid components in the reaction vessel 1 are separated through a filter screen 37, facilitating subsequent distillation and crystallization of the lithium alcohol solution. Finally, the switch 44 is turned on. The lithium alcohol solution reaches the distillation tank 41 through the connecting pipe 43. Then, the heating base 42 is activated to heat and distill the lithium alcohol solution in the distillation tank 41. The water is discharged through the gas outlet 45. At the same time, the second motor 474 is activated, which drives the first fan blade 475 to rotate, thereby cooling the distillation tank 41. Simultaneously, the third motor 483 is activated, which drives the second fan blade 484 to rotate, thereby further cooling the distillation tank 41. Finally, the fourth motor 486 is activated, which drives the lead screw 487 to rotate. The lead screw 487 drives the movable plate 481 to move up and down, and the movable plate 481 drives the second fan blade 484 to move up and down, resulting in better cooling of the distillation tank 41. By rapidly cooling the distillation tank 41 through the first and second fan blades 475 and 484, the lithium alcohol solution crystallizes quickly without the need for natural cooling, saving a lot of waiting time and improving work efficiency.
