Specific embodiments

[0031] The following are the preferred embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can also be made, and these improvements and refinements are also regarded as the protection scope of the present application.

[0032] Before introducing the technical solution of the present application, the technical problems in the related art will be introduced in detail.

[0033] During the preparation of lithium-ion battery slurry, solute powder is first put into a stirring device such as a stirring tank or a stirring box, and then a stirring paddle is used to stir the solute powder to make it evenly mixed. However, dust will be generated during the input and stirring of the solute powder, causing the powder to float, and some of the powder will adhere to the top cover of the stirring tank, that is, adhere to the inner top wall of the accommodation space in the stirring tank.

[0034] Subsequently, a liquid solvent will be continuously added to the stirring tank, and then the stirring paddle is used to stir the solvent and the solute to form a slurry, so that the solvent and the solute are dispersed and mixed evenly. However, the double planetary stirring tank is prone to splashing under high-speed rotation, and part of the mixed slurry will be thrown onto the top cover and mixed with the solute powder that has adhered to the top cover to form dry powder or dry material lumps. Such dry powder or dry material lumps will fall back into the slurry in the stirring tank due to the influence of equipment vibration or other mechanical actions during the stirring process, increasing the agglomerates in the slurry, affecting the dispersion effect of the slurry, resulting in abnormal dispersion of the slurry or even contamination of the slurry, reducing the utilization rate of the slurry, increasing the cost, and also increasing the cleaning efficiency of the stirring equipment.

[0035] In view of this, in order to solve the above problems, the present application provides a stirring device. Please refer to Figures 1-2 , Figure 1 which is a schematic cross-sectional view of the stirring device in an embodiment of the present application. Figure 2 is Figure 1 an exploded view of the stirring device shown. The stirring device 1 provided in this embodiment includes a housing 10, a top cover 20, a stirring member 30, and a scraper 40. An opening 100 is provided on one side of the housing 10. The top cover 20 is installed at the opening 100 of the housing 10 and encloses a accommodation space 200 with the housing 10. The accommodation space 200 is used to accommodate the solute and the solvent. The stirring member 30 is arranged in the accommodation space 200. The stirring member 30 can rotate around its axis and is used to stir the solute and the solvent. The scraper 40 is arranged in the accommodation space 200 and abuts against the top cover 20. The scraper 40 can rotate around its axis and is used to scrape the solute adhered to the top cover 20 and / or the mixture of the solute and the solvent.

[0036] The stirring device 1 provided in this embodiment can be applied in various fields and is mainly used for stirring various solute materials and solvent materials. Therefore, the application field of the stirring device 1 and the types of solute materials and solvent materials are not limited in this embodiment. This embodiment only makes a schematic description with the stirring device 1 applied to the field of lithium-ion battery slurry preparation.

[0037] The stirring device 1 mainly includes a housing 10, a top cover 20, a stirring member 30, and a scraper 40. The housing 10 is the casing of the stirring device 1, mainly used for installing various components and accommodating solute raw materials and solvent raw materials. An opening 100 is provided on one side of the housing 10 to facilitate the subsequent installation of the top cover 20. Optionally, the cross-sectional shape of the housing 10 is U-shaped, and the opening 100 is provided on the upper side of the housing 10.

[0038] The top cover 20 is the cover body in the stirring device 1, installed at the top opening 100 of the housing 10 to seal the opening 100, thereby sealing the internal space of the housing 10. In other words, the top cover 20 and the housing 10 can enclose a containing space 200, and this containing space 200 can be used to install various components such as the stirring member 30, the scraper 40, etc., and accommodate solute raw materials and solvent raw materials. Optionally, the material of the top cover 20 is a metal material, such as 304 stainless steel, which has good mechanical properties, such as strength, wear resistance, etc., and corrosion resistance.

[0039] The stirring member 30 can also be called a stirring paddle, which is arranged in the containing space 200. The stirring member 30 can rotate around its own axis, thereby stirring various materials arranged in the containing space 200. For example, it can stir the solute alone, or stir the solute and the solvent simultaneously.

[0040] As can be seen from the related art, when the stirring member 30 stirs the solute alone, the solute powder will adhere to the top cover 20. When the stirring member 30 stirs the solute and the solvent simultaneously, the mixture of the solute and the solvent will be thrown to the top cover 20 and mixed with the solute powder to form dry material lumps. The content of the solute in the dry material lumps will not only increase, but also be unevenly mixed. When it falls back into the slurry due to reasons such as mechanical vibration in the subsequent process, if the dry material lumps cannot be redistributed evenly with other slurries again, for example, when the dry material lumps fall in the later stage of stirring, the dry material lumps will not have time to be redistributed evenly with other slurries. This will lead to agglomeration in the slurry and affect the uniformity of the slurry mixing.

[0041] In this embodiment, a scraper 40 can be added on the basis of the above components. The scraper 40 can also be called a scraping knife or a scraping piece, mainly used to scrape impurities from the components. In this embodiment, the scraper 40 can be arranged in the containing space 200 and close to the top cover 20, so that the upper surface of the scraper 40 abuts against and fits with the lower surface of the top cover 20. In other words, the scraper 40 abuts against the inner top wall of the containing space 200.

[0042] The scraping plate 40 can rotate along its own axis. During the rotation process, the scraping plate 40 scrapes off the solute powder adhered to the top cover 20 and / or the slurry dry powder and dry material lumps thrown onto the top cover 20 and returns them to the slurry in the stirring tank body for re-stirring. It should be noted that in this embodiment, it is possible to scrape only the solute adhered to the top cover 20, or only the mixture of the solute and the solvent, or simultaneously scrape the solute adhered to the top cover 20 and the mixture of the solute and the solvent.

[0043] This method can not only prevent the deposition of dry materials at the position of the top cover 20, prevent the secondary pollution of the already mixed and stirred slurry during the stirring process, but also improve the utilization efficiency of the slurry and reduce costs.

[0044] In summary, the stirring device 1 provided in this application can be applied to various types of stirring tank bodies and various types of slurries. It can effectively reduce the agglomerates in the slurry, improve the utilization rate of the slurry, improve the dispersion effect and stability of the slurry, reduce costs, and can also eliminate the need to clean the top cover 20, thus improving the cleaning efficiency of the stirring device 1.

[0045] In this embodiment, the material of the scraping plate 40 is non-metallic, such as PP, PE, etc. The non-metallic scraping plate 40 avoids hard contact during continuous contact with the top cover 20, thereby preventing the metal of the metal top cover 20 from being scraped into the slurry, which would increase the materials in the slurry. In addition, the non-metallic scraping plate 40 has a low cost, is wear-resistant and easy to replace. Optionally, the material of the scraping plate 40 is non-magnetic, avoiding the adsorption effect with other magnetic components at the top cover 20, thus affecting the normal use of the magnetic components.

[0046] In this embodiment, the stirring member 30 is used to first stir the solute. The solute is in powder form, and part of the powdered solute will adhere to the top cover 20; the stirring member 30 is used to then stir the solute and the solvent, and part of the mixture of the solute and the solvent will also adhere to the top cover 20; the scraping plate 40 is used to rotate when the stirring member 30 stirs the solute, and / or the scraping plate 40 is used to rotate when the stirring member 30 stirs the solute and the solvent.

[0047] As can be seen from the above, the stirring member 30 first stirs the solute in powder form. At this time, due to dust generation, some of the powdered solute will adhere to the top cover 20. After the solute is mixed evenly, a liquid solvent is added to the stirring device 1, and then the solute and the solvent are stirred to form a uniform mixture. At this time, part of the mixture will be thrown onto the top cover 20, and some will be mixed with the solute that adhered to the top cover 20 before. In this embodiment, the rotation timing of the scraper 40 can be controlled to scrape different substances. For example, the scraper 40 can be rotated when the stirring member 30 stirs the solute, so as to scrape only the solute adhering to the top cover 20, so that the mixture thrown onto the top cover 20 subsequently will not be mixed with the solute adhering to the top cover 20.

[0048] Alternatively, the scraper 40 can be used to rotate when the stirring member 30 stirs the solute and the solvent. In this way, the mixture that has just been thrown onto the top cover 20 can be scraped off and made to fall back into the slurry again. At this time, although the dry material agglomerates have been mixed with the solute adhering to the top cover 20, due to timely scraping, the stirring member 30 can be used to remix the dry material agglomerates with the slurry evenly subsequently. Optionally, the scraper 40 is used to rotate at the initial stage of the stirring of the solute and the solvent by the stirring member 30. That is, when the stirring member 30 stirs the solute and the solvent, it can be divided into the initial stage of stirring, the middle stage of stirring, and the final stage of stirring. The scraper 40 can be made to start rotating at the initial stage of stirring, so as to scrape the dry material agglomerates into the slurry as early as possible, and reserve sufficient time for the subsequent remixing of the dry material agglomerates and the slurry evenly.

[0049] Or the scraper 40 can be used to rotate when the stirring member 30 stirs the solute, and the scraper 40 can be used to rotate when the stirring member 30 stirs the solute and the solvent. In other words, the scraper 40 starts to rotate when the stirring member 30 stirs the solute. When the solute adheres to the top cover 20, it is scraped off, and at the same time, when the mixture is thrown onto the top cover 20, it is also scraped off, further improving the dispersion uniformity and the utilization rate of the slurry.

[0050] In this embodiment, the scraper 40 can rotate synchronously with the stirring member 30. By making the scraper 40 rotate synchronously with the stirring member 30, the scraper 40 can be used to rotate when the stirring member 30 stirs the solute, and the scraper 40 can be used to rotate when the stirring member 30 stirs the solute and the solvent. During the rotation process, the scraper 40 scrapes the solute adhering to the top cover 20 and the mixture thrown on the top cover 20 into the slurry in the stirring tank for stirring, further improving the dispersion uniformity and the utilization rate of the slurry.

[0051] Of course, in other embodiments, the scraper 40 can also be used independently and does not rotate synchronously with the stirring member 30. The scraper 40 and the stirring member 30 rotate independently of each other.

[0052] Please refer to again Figures 1-2, in this embodiment, the stirring device 1 further includes a rotating shaft 60. One end of the rotating shaft 60 penetrates through the top cover 20 and is disposed in the accommodating space 200. The stirring member 30 is fixed to one end of the rotating shaft 60. The scraping plate 40 is fixed to the rotating shaft 60 near the top cover 20. The other end of the rotating shaft 60 is located outside the accommodating space 200, and the axis of the rotating shaft 60 is the axis of the stirring member 30 and the axis of the scraping plate 40.

[0053] In addition to the above components, the stirring device 1 can also be provided with a rotating shaft 60, so that one end of the rotating shaft 60, that is, the lower end, passes through the top cover 20 and inserts into the accommodating space 200. The stirring member 30 can be fixed to one end of the rotating shaft 60. The scraping plate 40 can also be fixed to the rotating shaft 60 and is close to the top cover 20, so that the scraping plate 40 can abut against the top cover 20. The other end of the rotating shaft 60 is located outside the accommodating space 200 and can be connected to components such as a motor, so that the rotating shaft 60 rotates. Thus, when the rotating shaft 60 rotates, the stirring member 30 and the scraping plate 40 can be driven to rotate synchronously, realizing the synchronous and precise control of the stirring member 30 and the scraping plate 40, and the axis of the rotating shaft 60 itself is the axis of the stirring member 30 and the axis of the scraping plate 40.

[0054] Please refer to again Figures 1-2 , in this embodiment, the stirring device 1 further includes a fixing member 50. The fixing member 50 is fixed to the rotating shaft 60, and the scraping plate 40 is fixed to the fixing member 50. In this embodiment, the scraping plate 40 can be indirectly fixed to the rotating shaft 60 through the fixing member, that is, the fixing member 50 is first fixed to the rotating shaft 60, and then the scraping plate 40 is fixed to the fixing member 50, so that the scraping plate 40 can be indirectly fixed to the rotating shaft 60, reducing the difficulty of fixed assembly.

[0055] Please refer to together Figures 3-5 , Figure 3 is the front view of the fixing member in an embodiment of the present application. Figure 4 is the top view of two fixing members in an embodiment of the present application. Figure 5 is Figure 4 is the schematic diagram when the two fixing members shown cooperate with the rotating shaft. In this embodiment, the stirring device 1 includes two fixing members 50. Each fixing member 50 includes an arc portion 51 and first fixing portions 52 provided on opposite sides of the arc portion 51. The two arc portions 51 can wrap around and abut against the outer peripheral side of the rotating shaft 60, and the two first fixing portions 52 are threadedly connected.

[0056] In this embodiment, two fixing members 50 may be added. The two fixing members 50 have the same structure, shape and size. Each structural member includes an arc-shaped portion 51 in the middle and first fixing portions 52 located on opposite sides of the arc-shaped portion 51. The arc-shaped portions 51 of the two fixing members 50 are used to wrap and abut against the outer peripheral side of the rotating shaft 60. The two first fixing portions 52 of the two fixing members 50 can be fixed together in the form of threaded connection, so that the two fixing members 50 can be fixed on the rotating shaft 60. Specifically, a first fixing portion 52 is provided on each side of the arc-shaped portion 51, so two first fixing portions 52 are provided on opposite sides of the arc-shaped portion 51, and two threaded holes 520 are provided on each first fixing portion 52. After the two arc-shaped portions 51 are wrapped and abutted and positioned, the threaded holes 520 of the two first fixing portions 52 facing each other can be arranged in correspondence, and then the bolts 54 and nuts 55 can be used for threaded connection.

[0057] In this embodiment, the shape formed by the two arc-shaped portions 51 is adapted to the circumferential shape of the rotating shaft 60. By making the shape formed by the two arc-shaped portions 51 adapted to the circumferential shape of the rotating shaft 60, the outer circumference of the rotating shaft 60 can be better wrapped and abutted. For example, when the circumferential shape of the rotating shaft 60 is circular, the shape of each arc-shaped portion 51 is semicircular, so the two arc-shaped portions 51 can be arranged to form a circle or a nearly circle.

[0058] Please refer to Figures 3-4 ,as well as Figures 6-8 , Figure 6 for Figure 4 The schematic diagram of the two fixing parts and the two scrapers shown is shown. Figure 7 for Figure 6 A front view of the two fixing members shown when they cooperate with the two scrapers. Figure 8 for Figure 7 In this embodiment, the stirring device 1 includes two scrapers 40, each of the fixing members 50 also includes a second fixing portion 53 disposed on the first fixing portion 52 away from the arc-shaped portion 51, one scraper 40 is threadedly connected to the two second fixing portions 53 on one side of the two fixing members 50, and the other scraper 40 is threadedly connected to the two second fixing portions 53 on the other side of the two fixing members 50.

[0059] In this embodiment, two scraping plates 40 can be provided. The two scraping plates 40 are fixed to opposite sides of the fixing member 50. Specifically, in addition to the arc portion 51 and the first fixing portion 52, the fixing member 50 may further include a second fixing portion 53. The second fixing portion 53 is provided on the side of the first fixing portion 52 away from the arc portion 51. Therefore, each fixing member 50 is successively the second fixing portion 53, the first fixing portion 52, the arc portion 51, the first fixing portion 52, and the second fixing portion 53 along its extending direction. After the two arc portions 51 and the rotating shaft 60 are wrapped and abutted, and fixed by the first fixing portion 52, at this time, the two second fixing portions 53 are also correspondingly arranged and have a gap. At this time, the scraping plate 40 can be inserted into the gap, and the scraping plate 40 and the two second fixing portions 53 are fixed by threaded connection. That is, one scraping plate 40 is threadedly connected to the two second fixing portions 53 on one side of the two fixing members 50, and the other scraping plate 40 is threadedly connected to the two second fixing portions 53 on the other side of the two fixing members 50. For example, two threaded holes 520 are provided on the second fixing portion 53, and the two threaded holes 520 of the two second fixing portions 53 are correspondingly arranged. Threaded holes 520 are also provided on the scraping plate 40. After the scraping plate 40 is arranged between the two second fixing portions 53 and the threaded holes 520 of the three components are correspondingly arranged, threaded connection can be performed by using bolts 54 and nuts 55.

[0060] Please refer to Figure 9 , Figure 9 FIG. is a cross-sectional schematic view of the stirring device in another embodiment of the present application. In this embodiment, a protruding portion 61 is provided on the circumferential side of the rotating shaft 60. The protruding portion 61 is located on the side of the fixing member 50 away from the top cover 20. The stirring device 1 further includes an elastic member 70 sleeved on the rotating shaft 60. Opposite sides of the elastic member 70 respectively abut against the protruding portion 61 and the fixing member 50, and the elastic member 70 is in a compressed state.

[0061] On the basis of adding the fixing member 50, in this embodiment, a circle of protrusions can be provided on the circumferential side of the rotating shaft 60 below the fixing member 50 to form the protruding portion 61. In this way, the elastic member 70 can be added, the elastic member 70 is sleeved on the rotating shaft 60, and one end of the elastic member 70 abuts against the protruding portion 61, and the other end abuts against the fixing member 50. At the same time, the elastic member 70 is in a compressed state. The elastic member 70 in the compressed state can give an upward elastic force to the fixing member 50 to prevent the fixing member 50 from shifting downward, ensuring that the scraping plate 40 and the top cover 20 can always be in an abutting state, and avoiding the inability to scrape the solute powder and the mixture of solute and solvent on the top cover 20 due to the gap between the scraping plate 40 and the top cover 20.
