A 1 mol / L solution has a pH of approximately 14 and pKb = -0.04. It can absorb carbon dioxide and moisture from the air. It is soluble in water, slightly soluble in ethanol, and insoluble in ether. As is well known, lithium hydroxide is a type of adsorbent. Mixing devices are generally used in the production process of lithium hydroxide adsorbents.

[0003] Chinese Utility Model Patent Publication No. CN 217312973 U discloses a mixing device for the production of lithium hydroxide adsorbent. This mixing device, through a mixing shell, positioning strips, positioning plate, first filter screen, second filter screen, third filter screen, pull-out plate, pull-out ring, and collection pipe, effectively filters impurities from the adsorbent during the production process, resulting in higher quality adsorbent and greater ease of use, further meeting user needs and bringing convenience to work. However, this mixing device for lithium hydroxide adsorbent production lacks a properly designed mixing structure. During mixing, it is difficult to stir and agitate materials at different heights, easily leading to poor mixing efficiency and affecting subsequent normal use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a mixing device for the production of lithium hydroxide adsorbent. It can effectively solve the problem that the existing technology does not have a mixing structure design, which makes it inconvenient to stir and turn the materials at different height levels during mixing, which easily leads to poor mixing efficiency and affects subsequent normal use.

[0005] The technical solution adopted by this utility model is: a mixing device for the production of lithium hydroxide adsorbent, including a mounting frame, a limiting plate fixedly installed on the top of the mounting frame, a limiting ring fixedly installed on the other end of the limiting plate away from the mounting frame, a mixing tank fixedly installed on the inner surface of the limiting ring, a bottom tank fixedly installed on the end of the mixing tank near the mounting frame, a top cover provided on the other end of the mixing tank away from the mounting frame, a liquid inlet assembly and a connecting seat fixedly installed on the other end of the top cover away from the mounting frame, a motor fixedly installed on the other end of the connecting seat away from the mixing tank, a connecting shaft fixedly installed on the output shaft of the motor, a rotating frame fixedly installed on the other end of the connecting shaft away from the motor, a rotating shaft fixedly installed on the outer surface of the rotating frame, and a connecting frame fixedly installed on the other end of the rotating frame away from the motor.

[0006] Preferably, the outer surface of the connecting frame is provided with an insert plate, the outer surface of the insert plate is provided with a through groove, and the outer surface of the insert plate is provided with a positioning bolt that penetrates the connecting frame and the insert plate.

[0007] Through the above technical solution, the positioning bolt can firmly fix the insert plate on the connecting frame, ensuring that the insert plate will not shake or fall off during the operation of the mixing device. The position of the insert plate on the connecting frame can be adjusted as needed. The flow path and mixing effect of the material in the mixing tank can be changed through the through groove, which improves the flexibility and adaptability of the device and can meet the requirements of different mixing processes.

[0008] Preferably, the through slots are provided in multiple identical manner, the cross-sectional shape of the insert plate is the same as the cross-sectional shape of the bottom tank, and the cross-sectional area of ​​the insert plate is smaller than the cross-sectional area of ​​the bottom tank.

[0009] Through the above technical solutions, the identical shape of the insert plate and the cross-section of the bottom tank facilitates the smooth flow of materials in the tank, reduces turbulence and dead zones, and multiple channels provide a variety of material flow channels. The material exchange and mixing degree in different areas can be controlled by adjusting the position of the insert plate. If the area of ​​the insert plate is smaller than the area of ​​the bottom tank, it will not hinder the overall circulation of materials in the tank, ensuring sufficient and uniform mixing and improving the consistency of product quality.

[0010] Preferably, the rotating frame has a cross-shaped structure, and the mixing tank and the bottom tank are an integral structure.

[0011] Through the above technical solutions, the cross-shaped rotating frame structure is stable and can evenly agitate the materials in the mixing tank when driven by the motor. This causes the materials to be subjected to shear force and centrifugal force in different directions, promoting the mixing effect. The integrated structure of the mixing tank and the bottom tank reduces the risk of leakage at the connection points, improves the overall strength and sealing of the device, and ensures that the mixing process is carried out in a stable environment, which is conducive to improving product quality and the service life of the device.

[0012] Preferably, an upper rotating cover, a rotating plate, and a lower rotating cover are rotatably mounted on the outer surface of the rotating shaft, and multiple identical upper rotating covers, rotating plates, and lower rotating covers are provided and are distributed at equal intervals.

[0013] Through the above technical solution, the equidistantly distributed upper cover, rotating plate and lower cover can stir and turn the material at different height levels when the rotating frame drives the rotating shaft to rotate. The upper cover and lower cover can change the flow direction of the material in the upper and lower areas, while the rotating plate enhances the stirring effect in the middle area. This layered stirring design makes the material mix more thoroughly and evenly.

[0014] Preferably, the outer surface of the mixing tank is provided with an observation window, and the other end of the bottom tank away from the mixing tank is provided with a discharge pipe, the outer surface of which is provided with a solenoid valve.

[0015] The above technical solution allows operators to monitor the mixing process in real time through the observation window, promptly detect abnormalities such as material clumping or abnormal liquid levels, and take corresponding measures to ensure the smooth progress of the mixing process and product quality. The solenoid valve controls the opening and closing of the discharge pipe, which is convenient and quick to operate and can accurately control the discharge quantity and discharge time, thereby improving the automation level of the equipment and the accuracy of production control.

[0016] Preferably, the liquid inlet assembly includes a mounting base, which is fixedly installed with the top cover and communicates with the mixing tank. A connecting pipe is fixedly installed at the other end of the mounting base away from the top cover, and a limiting seat is fixedly installed at the other end of the connecting pipe away from the mounting base. A filter frame is provided on the inner surface of the limiting seat, and a filter screen is provided on the inner surface of the filter frame.

[0017] Through the above technical solution, the filter frame and filter screen can effectively filter out impurities in the liquid, preventing impurities from entering the mixing tank and affecting the quality of the lithium hydroxide adsorbent. The mounting base ensures a stable connection between the liquid inlet component and the mixing tank and good liquid flow. Filtration can be carried out directly during liquid inlet. At the same time, when not in use, it is also convenient to quickly replace the filter element, thereby avoiding the inconvenience of subsequent replacement after long-term use.

[0018] Compared with the prior art, the present invention provides a mixing device for the production of lithium hydroxide adsorbent, which has the following advantages:

[0019] 1. The mixing device for lithium hydroxide adsorbent production features a stable "+" shaped rotating frame structure. When driven by a motor, it can evenly agitate the materials in the mixing tank, subjecting the materials to shear and centrifugal forces in different directions, thus promoting the mixing effect. The equidistantly distributed upper and lower rotating covers can stir and tumble the materials at different heights when the rotating frame drives the rotating shaft. The upper and lower rotating covers can change the flow direction of the materials in the upper and lower areas, while the rotating plates enhance the stirring effect in the middle area, making the material mix more thoroughly and evenly.

[0020] 2. The mixing device for lithium hydroxide adsorbent production, with its filter frame and filter screen, can effectively filter out impurities in the liquid, preventing impurities from entering the mixing tank and affecting the quality of the lithium hydroxide adsorbent. It can be used for filtration directly during liquid feeding, and when not in use, it facilitates quick replacement of the filter elements, thus avoiding the inconvenience of subsequent replacement after long-term use.

[0021] 3. The mixing device for lithium hydroxide adsorbent production features identically shaped baffles and a bottom tank cross-section, which facilitates smooth material flow within the tank, reducing turbulence and dead zones.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1: As Figure 1-7 As shown, the present invention provides a mixing device for the production of lithium hydroxide adsorbent, including a mounting frame 1. A limiting plate 2 is fixedly installed on the top of the mounting frame 1. A limiting ring 3 is fixedly installed on the other end of the limiting plate 2 away from the mounting frame 1. A mixing tank 4 is fixedly installed on the inner surface of the limiting ring 3. A bottom tank 5 is fixedly installed on the end of the mixing tank 4 near the mounting frame 1. A top cover 6 is provided on the other end of the mixing tank 4 away from the mounting frame 1. An inlet assembly 7 and a connecting seat 8 are fixedly installed on the other end of the top cover 6 away from the mounting frame 1. A motor 9 is fixedly installed on the other end of the connecting seat 8 away from the mixing tank 4. A connecting shaft 10 is fixedly installed on the output shaft of the motor 9. A rotating frame 11 is fixedly installed on the other end of the connecting shaft 10 away from the motor 9. A rotating shaft 12 is fixedly installed on the outer surface of the rotating frame 11. A connecting frame 16 is fixedly installed on the other end of the rotating frame 11 away from the motor 9.

[0032] Specifically, the outer surface of the connecting frame 16 is provided with an insert plate 17, the outer surface of the insert plate 17 is provided with a through groove 18, and the outer surface of the insert plate 17 is provided with a positioning bolt 19 that passes through the connecting frame 16 and the insert plate 17. The advantage is that the positioning bolt 19 can firmly fix the insert plate 17 on the connecting frame 16, ensuring that the insert plate 17 will not shake or fall off during the operation of the mixing device. The position of the insert plate 17 on the connecting frame 16 can be adjusted as needed. The flow path and mixing effect of the material in the mixing tank 4 can be changed through the through groove 18, which improves the flexibility and adaptability of the device and can meet the requirements of different mixing processes.

[0033] Specifically, multiple identical channels 18 are provided. The cross-sectional shape of the insert plate 17 is the same as that of the bottom tank 5, but the cross-sectional area of ​​the insert plate 17 is smaller than that of the bottom tank 5. The advantage is that the identical shape of the insert plate 17 and the cross-section of the bottom tank 5 facilitates the smooth flow of materials in the tank, reduces turbulence and dead zones, and the multiple channels 18 provide a variety of material flow channels. The material exchange and mixing degree in different areas can be controlled by adjusting the position of the insert plate 17. The smaller area of ​​the insert plate 17 than that of the bottom tank 5 will not hinder the overall circulation of materials in the tank, ensuring sufficient and uniform mixing and improving the consistency of product quality.

[0034] Specifically, the rotating frame 11 has a cross-shaped structure, and the mixing tank 4 and the bottom tank 5 are integrated. The advantages are that the cross-shaped rotating frame 11 has a stable structure and can evenly agitate the material in the mixing tank 4 when driven by the motor 9, so that the material is subjected to shear force and centrifugal force in different directions, which promotes the mixing effect. The integrated structure of the mixing tank 4 and the bottom tank 5 reduces the risk of leakage at the connection points, improves the overall strength and sealing of the device, and ensures that the mixing process is carried out in a stable environment, which is conducive to improving product quality and the service life of the device.

[0035] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0036] Specifically, an upper rotating cover 13, a rotating plate 14, and a lower rotating cover 15 are rotatably mounted on the outer surface of the rotating shaft 12. Multiple upper rotating covers 13, rotating plates 14, and lower rotating covers 15 are provided and are equidistantly distributed. The advantage is that when the rotating frame 11 drives the rotating shaft 12 to rotate, the equidistantly distributed upper rotating covers 13, rotating plates 14, and lower rotating covers 15 can stir and turn the material at different height levels. The upper rotating covers 13 and lower rotating covers 15 can change the flow direction of the material in the upper and lower areas, while the rotating plate 14 enhances the stirring effect in the middle area. This layered stirring design makes the material mix more thoroughly and evenly.

[0037] Specifically, an observation window 20 is provided on the outer surface of the mixing tank 4, and a discharge pipe 21 is provided at the other end of the bottom tank 5 away from the mixing tank 4. A solenoid valve 22 is provided on the outer surface of the discharge pipe 21. The advantages are that the observation window 20 allows operators to monitor the mixing process in real time and promptly detect abnormalities such as material agglomeration or abnormal liquid level, so as to take corresponding measures to ensure the smooth progress of the mixing process and product quality. The solenoid valve 22 controls the opening and closing of the discharge pipe 21, which is convenient and quick to operate and can accurately control the discharge amount and discharge time, thereby improving the automation level of the device and the accuracy of production control.

[0038] Specifically, the liquid inlet assembly 7 includes a mounting base 701, which is fixedly installed with the top cover 6 and communicates with the mixing tank 4. A connecting pipe 702 is fixedly installed at the other end of the mounting base 701 away from the top cover 6, and a limiting seat 703 is fixedly installed at the other end of the connecting pipe 702 away from the mounting base 701. A filter frame 704 is provided on the inner surface of the limiting seat 703, and a filter screen 705 is provided on the inner surface of the filter frame 704. The advantage is that the filter frame 704 and the filter screen 705 can effectively filter out impurities in the liquid and prevent impurities from entering the mixing tank 4 and affecting the quality of the lithium hydroxide adsorbent. The mounting base 701 ensures a stable connection between the liquid inlet assembly 7 and the mixing tank 4 and good liquid flow. Filtration can be carried out directly during liquid inlet. At the same time, when not in use, it is also convenient to quickly replace the filter element, thereby avoiding the inconvenience of subsequent replacement after long-term use.

[0039] Working principle: During use, the positioning bolt 19 firmly fixes the insert plate 17 to the connecting frame 16, ensuring that the insert plate 17 will not shake or fall off during the operation of the mixing device. The position of the insert plate 17 on the connecting frame 16 can be adjusted as needed. The flow path and mixing effect of the material in the mixing tank 4 are changed through the through groove 18, which improves the flexibility and adaptability of the device and can meet the requirements of different mixing processes. The identical shape of the insert plate 17 and the cross-section of the bottom tank 5 facilitates the smooth flow of material in the tank, reducing turbulence and dead zones. Multiple through grooves 18 provide a variety of material flow channels. The position of the insert plate can be adjusted by changing the flow path of the material in the tank. Position 17 controls the material exchange and mixing degree in different areas. Since the area of ​​the insert plate 17 is smaller than that of the bottom tank 5, it will not hinder the overall circulation of materials within the tank, ensuring sufficient and uniform mixing and improving product quality consistency. The cross-shaped rotating frame 11 has a stable structure and, when driven by the motor 9, can evenly agitate the materials within the mixing tank 4, subjecting them to shear and centrifugal forces in different directions, thus promoting mixing. The integrated structure of the mixing tank 4 and the bottom tank 5 reduces the risk of leakage at the connection points, improves the overall strength and sealing of the device, and ensures that the mixing process takes place in a stable environment. To improve product quality and extend the lifespan of the equipment, the equidistantly distributed upper rotating cover 13, rotating plate 14, and lower rotating cover 15, when the rotating frame 11 drives the rotating shaft 12 to rotate, can stir and agitate materials at different heights. The upper and lower rotating covers 13 and 15 can change the flow direction of materials in the upper and lower areas, while the rotating plate 14 enhances the stirring effect in the middle area. This layered stirring design makes the material mix more thoroughly and evenly. The observation window 20 allows operators to monitor the mixing process in real time, promptly detect abnormalities such as material clumping or abnormal liquid levels, and take corresponding measures to ensure the smooth progress of the mixing process. To ensure product quality, the solenoid valve 22 controls the opening and closing of the discharge pipe 21, making operation convenient and quick. It can accurately control the discharge volume and discharge time, improving the automation level of the device and the accuracy of production control. The filter frame 704 and filter screen 705 can effectively filter out impurities in the liquid, preventing impurities from entering the mixing tank 4 and affecting the quality of the lithium hydroxide adsorbent. The mounting base 701 ensures a stable connection between the liquid inlet assembly 7 and the mixing tank 4 and good liquid flow. Filtration can be carried out directly during liquid inlet. At the same time, when not in use, it is also convenient to quickly replace the filter elements, thus avoiding the inconvenience of subsequent replacement after long-term use.
