Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to a cleaning tool for a lithium battery slurry mixer. Background Technique

[0002] A lithium battery is a battery that uses a lithium-containing material as an electrode and conducts lithium-ion exchange using a special electrolyte solution. With the improvement of people's environmental awareness and the popularization of intelligent products, lithium batteries have become the mainstream in today's battery products due to their excellent electrical performance and environmental friendliness. The production process of lithium batteries involves processes such as homogenization, coating, sheet making, assembly, and grading. Among them, the homogenization process is one of the important links in the lithium battery manufacturing process, and the quality of the slurry produced in the homogenization process directly affects the subsequent processes and the performance of the finished battery.

[0003] The homogenization process generally uniformly mixes and disperses electrode main materials, solvents, binders, additives, etc. to obtain a suspension-like battery slurry. During the manufacturing process of this battery slurry, a mixer is required to fully stir, knead, and disperse it. Since the final product is a suspension, after the battery slurry is manufactured, there are residues on the surfaces of some components such as the stirring paddle, dispersion disk, and inner wall of the stirring barrel of the mixer. If not cleaned in time, the residual slurry will solidify and agglomerate, increasing the operating burden of the equipment, increasing the energy consumption of the equipment operation, reducing the stirring and dispersion efficiency of the slurry, and at the same time affecting the quality of the subsequent slurry.

[0004] Considering the particularity of the slurry, it is difficult to rinse it clean with water or other solvents, and it is also easy to cause waste of resources. The control of metals in the slurry manufacturing process is extremely strict, so there should be no exposed metals on the surface of the slurry mixer cleaning tool, especially metal screws that are easy to fall off should be avoided on the cleaning tool.

[0005] In summary, under the existing conditions, there is no reasonable and effective tool for cleaning a lithium battery slurry mixer, so this article designs a cleaning tool for a lithium battery slurry mixer that saves solvent cleaning and has no hidden danger of metal introduction.

These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the relevant components of the present utility model.

[0023] According to the technical solution of the present utility model, without changing the essence of the present utility model, those of ordinary skill in the art can propose various replaceable structural forms and implementation manners. Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present utility model, and should not be regarded as the whole of the present utility model or as a limitation or restriction on the technical solution of the present utility model.

[0024] The technical solution of the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Embodiment 1, as Figure 1 and Figure 2 shown, a cleaning tool for a lithium battery slurry mixer includes a scraping plate 1, an elbow 2 and a rod body. One end of the elbow 2 is connected to the back surface of the scraping plate 1, and the other end is connected to the top of the rod body. From Figure 1and Figure 2 From above, the cleaning tool looks like a protruding structure, but the scraper plate 1 is an isosceles triangle structure, the sharp corner of the triangle is set downward, and the front of the scraper plate 1 is a plane, and the back of the scraper plate 1 is provided with a slope.

[0026] In practice, the outer surface of the scraper plate 1 is coated with a plastic layer with a thickness of 1 mm, and the plastic layer is a Teflon coating. The scraper plate 1 can also be directly made of a 4-10 mm thick Teflon material, with a thickness of 4-6 mm at the edge and 7-10 mm in the middle, and the slope of the slope is 10-30°. Figure 3 The scraper plate 1 is in the shape of an isosceles triangle, with a length of 30 to 50 cm and a height of 20 to 25 cm. The surface of the scraper plate 1 is evenly coated with Teflon material to avoid the risk of metal falling caused by fixing with stainless steel screws and the risk of exposed metal contaminating the slurry.

[0027] The present scheme provides a cleaning tool for a lithium battery slurry mixer, in which the scraper plate 1 is triangular and stable, and has a smaller area than a rectangular scraper plate of the same length and width. The reduction in required materials reduces the weight of the tool, and the three corners of the scraper plate 1 can be used to break hard agglomerated slurry. The scraper plate itself has a certain slope, which is conducive to cleaning thick slurry and breaking hard agglomerates or hard materials.

[0028] See also Figure 3 Specifically, the back of the scraper board 1 is provided with a first slope 11, a second slope 12, and a third slope 13. The first slope 11 is located at the top of the back of the scraper board 1, and the second slope 12 and the third slope 13 are located on both sides of the bottom of the back of the scraper board 1, and the structure of the second slope 12 is the same as that of the third slope 13, thereby forming a rearward convex isosceles triangle structure.

[0029] As a preferred solution, a triangular plane 15 is also provided on the back of the scraper 1, and the extension ends of the first slope 11, the second slope 12, and the third slope 13 extend to the three edges of the triangular plane 15, and the slope of the three slopes is 10 to 30 degrees. In addition, a connector 14 is provided in the middle of the back of the scraper 1, and a thread is provided inside the connector 14 to facilitate connection with the elbow 2. The three slopes are close to the connector 14, and the scraper 1 is connected to one end of the elbow 2 through the connector 14.

[0030] Embodiment 2, on the basis of embodiment 1, as Figure 4As shown in the figure, a cleaning tool for a lithium battery slurry mixer. During implementation, the elbow 2 has an arc-shaped structure. Of course, it can also be an L-shaped right-angled structure, both of which can achieve the function of removing the caking of lithium battery slurry. One end of the elbow 2 is provided with an external thread 21 that is threadedly connected to the scraping plate 1, and the other end of the elbow 2 is provided with an internal thread 23 that is threadedly connected to the rod body. Therefore, both ends of the elbow 2 are connected by threads.

[0031] During implementation, the elbow 2 is made of a pipe body. The outer diameter of the pipe body is 5 - 6 cm, and the wall thickness is 1 - 1.2 cm. It is preferably made of a stainless steel round pipe and lined with a Teflon coating material of 0.2 - 0.3 mm. A scraping strip 22 is provided on the inner side of the bend of the elbow 2. The scraping strip 22 has a V-shaped structure. The scraping strip 22 is arranged along the shape of the elbow 2, so it looks like a sickle. The outer surface of the scraping strip 22 is also coated with Teflon material and is integrally formed with the elbow 2 during manufacturing. The width of the protruding part of the scraping strip 22 is 1 - 2 cm, and the thickness is 3 - 5 mm.

[0032] The scraping plate 1 is connected to the elbow 2 by a threaded method. The reason for not using a movable connection method with multiple angles is mainly to consider that the angle of the movable connection part cannot stably maintain the pulling force angle to handle hard caked slurry, and it is prone to damage after long-term use. There is a sickle-shaped scraping strip 22 integrally formed with the Teflon material on the elbow 2. The sickle-shaped scraping strip 22 on the inner side of the elbow 2 can be used to supplement the cleaning of some areas that the scraping plate cannot operate (such as: the columnar shaft of the dispersion disk of the mixer). To a certain extent, the elbow 2 plays a role in strengthening the structural strength and at the same time avoids the problem that the liquid slurry slides down along the rod and affects the operation.

[0033] Example 3. On the basis of Example 1, the rod body includes an upper rod 3 and a lower rod 5. The upper rod 3 and the lower rod 5 are movably connected axially. The rod body of the cleaning tool is movably connected axially, which has the function of being telescopic, is suitable for mixers of different capacities, can clean most parts inside the mixer, avoids the safety hazards of the operator's body entering the mixer range, and reduces the risk of some foreign objects that may be brought in by the operator contaminating the slurry.

[0034] The upper rod 3 is made of a stainless steel round tube with an outer diameter of 3 - 4 cm and a wall thickness of 1 - 1.2 cm, and is lined with a Teflon material with a thickness of 0.2 - 0.3 mm. The lower rod 5 is made of a stainless steel round tube with an outer diameter of 5 - 6 cm and a wall thickness of 1 - 1.2 cm, and is lined with a Teflon material with a thickness of 0.2 - 0.3 mm. As a preferred solution, the upper rod 3 is movably connected to the lower rod 5 through a locking assembly 4. The two are connected through a stainless steel locking device assembly 4 lined with a Teflon material with a thickness of 0.2 - 0.3 mm. Among them, the locking assembly 4 can be a sleeve with openings at both ends. The two ends of the sleeve are respectively threadedly connected to the upper rod 3 and the lower rod 5. By rotating, a certain telescopic dimension can be adjusted, and then the overall length of the rod body can be adjusted. The locking assembly 4 can also be a locking structure similar to an umbrella. Using the structure of the sleeve and using rollers to pop out and then clamp when the sleeve reaches a certain length, so that the upper rod 3 and the lower rod 5 can be temporarily clamped and fixed, and when retracting, it can be manually pulled back with force.

[0035] Example 4, on the basis of Example 1, a handle 6 is provided at the bottom of the rod body to facilitate the staff to hold. As a preferred solution, a hand guard 61 is welded and fixed to the top of the handle 6, and an anti-slip leather sleeve 62 is provided on the outer peripheral surface of the handle 6, and anti-slip patterns are provided on the outer wall of the anti-slip leather sleeve 62. The bottom handle 6 is provided with a hand guard 61, which can block the slurry or foreign objects, and can also help to hold more tightly while providing protection; the surface of the handle 6 is engraved with a diamond pattern lining rubber leather sleeve, which can increase the friction and also improve the holding feeling to a certain extent. During production, the handle 6 is made of a round tube body in the shape of a disc with a diameter of 8 - 10 cm and a thickness of 1 - 2 mm, or a disc with a thickness of 5 - 10 mm. The anti-slip leather sleeve 62 is sleeved on the handle 6 to form the handle 6 component together. Its structure can refer to the hand guard accessories of swords in existing products. The surface of the handle 6 is sprayed with Teflon material. The hand guard 61 is fixedly sleeved with the cylindrical handle 6. An anti-slip rubber leather sleeve with a diamond pattern lining is provided on the outer peripheral surface of the handle 6, and it is connected to the tail of the lower rod 5 through a thread.

[0036] To sum up, when this cleaning tool for lithium battery slurry mixers is in use, it can clean efficiently without using solvent flushing. Each component is connected and fixed by threads, and there is no risk of metal components falling off and introducing potential hazards. It is suitable for use in lithium battery slurry mixers.
