Description

Technical Field

[0001] This utility model relates to the technical field of reaction devices, and in particular to a battery-grade lithium carbonate reaction device. Background Technology

[0002] Lithium carbonate is an important raw material for fine chemical production and is widely used in batteries, ceramics, glass, aluminum smelting, electronics, and pharmaceutical industries. Its low expansion properties can lower the sintering temperature of ceramics, improve the viscosity, density, thermal expansion, and surface hardness of glass, reduce spots and bubbles, and increase the surface tension and electrochemical stability of glass. Lithium carbonate produced using this method has high energy storage capacity and good cycle life. The key technology for producing battery-grade lithium carbonate via the carbonation method lies in controlling the reaction crystallization process to obtain lithium carbonate crystals with good particle size distribution and crystal structure. Developing and manufacturing a highly effective crystallization reactor is crucial for achieving controllable nucleation and growth of lithium carbonate crystals, thereby obtaining well-distributed particles and highly complete crystal development.

[0003] Chinese utility model CN219596623U discloses a reaction device for producing battery-grade lithium carbonate. It features a premixing structure designed to increase mixing efficiency and achieve faster, more uniform mixing. The principle involves two feeding pipes on the reaction vessel. When material is fed through one pipe, the falling material contacts a guide plate, causing the guide plate to move downwards and open the bottom of the other feeding pipe. Another material is then added from inside the other feeding pipe, achieving premixing of the two materials on the guide plate.

[0004] However, existing devices simply bring the two materials into direct contact, resulting in insufficient premixing and poor mixing efficiency. Therefore, a reaction device with better premixing efficiency was designed to address the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a battery-grade lithium carbonate reaction device to solve the problems mentioned in the background art.

[0006] The technical solution adopted in this utility model is:

[0007] A battery-grade lithium carbonate reaction apparatus, comprising:

[0008] A reaction vessel is provided with an internal stirring rod driven to rotate by a bottom motor; a feeding pipe is located at the top of the reaction vessel; a mixing assembly is provided inside the reaction vessel, the mixing assembly further comprising: a shell located on the inner side wall of the top of the reaction vessel; a hole formed at the bottom of the mixing assembly; a rotating column whose bottom penetrates through the top of the reaction vessel and the shell, and is rotatably connected to the reaction vessel, and whose bottom is connected to the stirring rod; a fan blade located on the outer side wall of the rotating column; a connecting pipe located on one side of the shell, with one end of its top connected to the bottom of the feeding pipe; an adjusting assembly is provided inside the rotating column for adjusting its connection with the stirring rod.

[0009] Optionally, the mixing component further includes: a second fan blade disposed on the outer side wall of the rotating column.

[0014] Optionally, the adjustment component further includes a baffle disposed at the bottom of the rotating column.

[0015] Optionally, the adjustment component further includes a square pyramid disposed at the bottom of the rotating column.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The reaction apparatus uses a mixing component that rotates a rotating column driven by a stirring rod. Liquid raw materials are added to the interior of the shell via a feeding pipe and a connecting pipe. The rotating column then drives a fan blade to stir the liquid inside, premixing it before it is discharged from the bottom orifice. Compared to existing devices, this stirring function provides a better premixing effect. Attached Figure Description

They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] The current technology involves two feed pipes on the reaction vessel. When material is fed through one pipe, the falling material contacts a baffle plate, which moves the baffle plate downwards to open the bottom of the other feed pipe. Then, another material is added through the other feed pipe, allowing the two materials to be premixed on the baffle plate. However, existing devices simply bring the two materials into direct contact, resulting in insufficient premixing and poor mixing efficiency.

[0029] like Figure 1-4 As shown, this embodiment of the invention provides a battery-grade lithium carbonate reaction device.

[0030] The system includes: a reaction vessel 11, which has a stirring rod 12 inside and is driven to rotate by a bottom motor; a feeding pipe 13 located at the top of the reaction vessel 11; a mixing assembly 2 located inside the reaction vessel 11, the mixing assembly 2 further including: a shell 21 located on the inner side wall of the top of the reaction vessel 11; a hole 22 located at the bottom of the mixing assembly 2; a rotating column 23, the bottom of which passes through the top of the reaction vessel 11 and the shell 21 and is rotatably connected to the reaction vessel 11, and the bottom of which is connected to the stirring rod 12; a fan blade 24 located on the outer side wall of the rotating column 23; a connecting pipe 25 located on one side of the shell 21, and one end of which is connected to the bottom of the feeding pipe 13; and an adjusting assembly 3 located inside the rotating column 23 for adjusting the connection with the stirring rod 12.

[0031] In use, first connect the bottom of the rotating column 23 to the stirring rod 12 using the adjusting component 3, then connect the motor at the bottom of the reaction vessel 11 to an external power source, and drive the stirring rod 12 to rotate while simultaneously rotating the rotating column 23. Then, add the reaction liquid from the inside of the feeding pipe 13. The liquid will flow through the connecting pipe 25 into the inside of the shell 21. At this time, the rotating column 23 rotates, driving the fan blade 24 to rotate, which can premix the two liquids inside the shell 21. Then, the liquid flows out from the hole 22 at the bottom of the shell 21 into the inside of the reaction vessel 11. At this time, the stirring rod 12 can mix the liquid inside.

[0032] Furthermore, the mixing component 2 also includes a second fan blade 26, disposed on the outer side wall of the rotating column 23.

[0033] The design of the second fan blade 26 allows the liquid to be dispersed when it flows out from inside the shell 21, so that it can be evenly sprayed inside the reaction vessel 11.

[0034] Furthermore, both the first fan blade 24 and the second fan blade 26 are provided with six sets.

[0035] There are six groups that can be set to increase the blending effect and make the blending efficiency higher.

[0036] Furthermore, the mixing component 2 also includes a plate 27, which is fixedly disposed on the outer side wall of the bottom end of the rotating column 23.

[0037] The design of plate 27 can block the downstream liquid, allowing it to make better contact with fan blade 26.

[0038] Furthermore, the adjustment component 3 includes: a rectangular groove 31, formed at the top of the stirring rod 12; a rectangular rod 32, the top end of which is inserted into the interior of the rotating column 23, and the outer side wall of which is in contact with the inner side wall of the rotating column 23; and a threaded rod 33, the top end of which passes through the rectangular rod 32 and the inner side wall of the rotating column 23, and is threadedly connected to the rectangular rod 32 and rotatably connected to the rotating column 23.

[0039] During adjustment, it is only necessary to control the rotation of the threaded rod 33. When it rotates, it is threadedly connected to the rectangular rod 32. At the same time, the inner wall of the rotating column 23 restricts the rotation of the rectangular rod 32. Therefore, when the threaded rod 33 rotates, it can drive the rectangular rod 32 to extend out from the inside of the rotating column 23 and insert into the rectangular groove 31 at the top of the stirring rod 12 for connection. This allows the stirring rod 12 to rotate together with the rotating column 23.

[0040] Furthermore, the adjustment component 3 also includes a knob 34, which is disposed at the top of the threaded rod 33.

[0041] The design of the knob 34 makes it easy to grip and control the rotation of the threaded rod 33. At the same time, the grooves on the surface of the knob 34 can increase friction when rotating.

[0042] Furthermore, the adjustment component 3 also includes a baffle 35, which is disposed at the bottom of the rotating column 23.

[0043] The design of the baffle 35 can prevent the threaded rod 33 from disengaging from the rectangular rod 32 when it rotates.

[0044] Furthermore, the adjustment component 3 also includes a four-sided pyramid 36, which is disposed at the bottom of the rotating column 23.

[0045] The pointed design at the bottom of the square pyramid 36 makes it relatively easier to insert into the rectangular slot 31.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
