Description

Technical Field

[0001] The present invention relates to the technical field of mixing equipment, and in particular to a lithium battery raw material mixing equipment. Background Art

[0002] Amidst the rapid development of the new energy industry, lithium-ion batteries, with their advantages such as high energy density and long cycle life, are widely used in electric vehicles, energy storage systems, 3C electronics, and other fields. In the lithium-ion battery production process, raw material mixing is a key step in determining battery performance, and the performance of the equipment is closely related to the quality of the mixing. However, the lithium-ion battery raw material mixing equipment currently on the market faces numerous challenges that need to be addressed, hindering improvements in lithium-ion battery product quality and production efficiency.

[0003] On the one hand, the stirring structure design of traditional mixing equipment is relatively simple, making it difficult to achieve efficient and uniform mixing of raw materials. Most equipment uses simple single-axis stirring or dual-axis parallel stirring methods, and the layout of the stirring blades is unreasonable. Effective shear force and turbulence effect cannot be formed during the stirring process, resulting in agglomerates and mixing dead corners in the mixed liquid. Especially for raw materials with complex components and extremely high requirements for mixing uniformity such as electrolytes, traditional equipment is difficult to achieve ideal mixing effects in a short time, which not only prolongs the production cycle, but may also affect the electrochemical performance of lithium batteries due to uneven mixing, reducing the battery's charging and discharging efficiency and service life.

[0004] On the other hand, existing mixing equipment has limitations in improving mixing efficiency. It lacks optimized design of fluid dynamics during the mixing process and cannot fully utilize the motion characteristics of the stirring blades to promote the circulation and diffusion of the liquid, resulting in long mixing time and high energy consumption, which makes it difficult to meet the high efficiency and energy-saving needs of large-scale industrial production.

[0005] Furthermore, traditional lithium battery raw material mixing equipment is not easy to maintain. Complex equipment structures and poorly designed access hatches make cleaning and repairing the mixing tank difficult, consuming significant manpower and time.

[0006] In summary, the development of a lithium battery raw material mixing equipment that can achieve efficient and uniform mixing, has good fluid stirring effect and is easy to maintain has become an urgent need to improve the quality and efficiency of lithium battery production and promote the development of the new energy industry. The lithium battery raw material mixing equipment of the present invention came into being based on this background. Summary of the Invention

DETAILED DESCRIPTION

[0033] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0034] like Figures 1-9As shown, a lithium battery raw material mixing device provided by an embodiment of the present invention includes a bracket 101, a mixing tank 102 is fixedly installed in the bracket 101, a driving motor 103 is fixedly installed on the outer wall of one side of the bracket 101, and the driving end of the driving motor 103 is rotatably connected to a rotating shaft 104, the rotating shaft 104 is rotatably installed in the mixing tank 102, and the outer wall of the rotating shaft 104 is fixedly installed with a first stirring shaft 105 and a second stirring shaft 106 distributed at equal distances, and the first stirring shaft 105 and the second stirring shaft 106 are staggered, and the first stirring shaft 105 and the second stirring shaft 106 are kept vertical, and both ends of the first stirring shaft 105 and the second stirring shaft 106 are fixedly installed with stirring shafts. The blades 107 are staggered between adjacent stirring blades 107. A feeding cover 108 is installed on the outer wall of one side of the mixing tank 102, and a feeding cylinder 109 is installed on the upper surface of the feeding cover 108. A discharge cover 110 is installed on the bottom end of the mixing tank 102, and a discharge cylinder 111 is installed on the lower surface of the discharge cover 110. A detection port is also provided at the top of the mixing tank 102, and also includes: a flow disturbance mechanism, a flow disturbance mechanism is arranged on one side of the mixing tank 102, and is used to disturb the mixed liquid in the mixing tank 102 up and down; a sealing mechanism, a sealing mechanism is arranged below the discharge cylinder 111, and is used to seal the discharge cylinder 111; an opening and closing mechanism, an opening and closing mechanism is arranged above the mixing tank 102, and is used to open and close the inspection port.

[0035] During use, the operator can add different stock solutions in proportion to the mixing tank 102 through the adding cover 108 and the adding barrel 109 according to the lithium battery electrolyte mixing formula, and then the rotating shaft 104 can be driven to rotate by the driving motor 103. Since the first stirring shaft 105 and the second stirring shaft 106 outside the rotating shaft 104 are staggered, and the first stirring shaft 105 and the second stirring shaft 106 are kept vertical, and the stirring blades 107 at the ends of the first stirring shaft 105 and the second stirring shaft 106 are staggered, when the first stirring shaft 105 and the second stirring shaft 106 rotate with the rotating shaft 104, the vertically distributed stirring blades 107 will form an orthogonal shear force in the intersection area. For example, the horizontal flow rate generated by the radial stirring blade 107 is equal to the axial flow rate. The vertical flow velocities generated by the stirring blades 107 are perpendicular to each other, forming a high shear area at the intersection, which can effectively break up the agglomerates in the mixed liquid and improve the dispersion efficiency. Furthermore, the liquid in the mixing tank 102 can be disturbed by the flow disturbance mechanism, so that the liquid keeps rising and falling in the mixing tank 102, which can further improve the mixing efficiency. When the liquid in the mixing tank 102 is completely mixed, the collection bucket containing the mixed liquid can be placed under the bracket 101, and then the sealing mechanism for the discharge barrel 111 is released, so that the mixed liquid can be discharged and collected through the discharge barrel 111, which is very convenient to use. Furthermore, the opening and closing mechanism can be used to open and close the inspection port at the top of the mixing tank 102, which is more convenient for inspection and maintenance of the inside of the mixing tank 102 and has a better use effect.

[0036] As an embodiment of the present invention, please refer to Figure 2 The outer side of the rotating shaft 104 is also fixedly mounted with a symmetrically distributed first spiral blade 201 and a second spiral blade 202, and the spiral direction of the first spiral blade 201 is opposite to that of the second spiral blade 202. The two sets of opposite-direction first spiral blades 201 and second spiral blades 202 form a counterflow of fluids flowing in opposite directions on both sides of the rotating shaft 104, generating a high-intensity turbulent vortex in the middle of the rotating shaft 104, forming an impact flow, which can instantly increase the local shear rate of the liquid, further accelerate the mixing rate, and achieve better use effect.

[0037] As an embodiment of the present invention, please refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 6The flow-disturbing mechanism includes a vertical box 301 fixedly mounted on the side wall of the mixing tank 102. The bottom end of the vertical box 301 is connected to an inclined cover 302, and the end of the inclined cover 302 is connected to the side wall of the discharge cover 110. A connecting rod 305 is fixedly mounted on the outer wall of one side of the vertical box 301, and a piston box 304 is fixedly mounted on the end of the connecting rod 305. The piston box 304 and the vertical box 301 are connected through a connecting channel 303. The bottom end of the piston box 304 is provided with a fixed port. , and a first electric telescopic rod 307 is fixedly installed in the fixed mouth, a piston block 308 is fixedly installed at the telescopic end of the first electric telescopic rod 307, a sealing sleeve 309 is sleeved on the outside of the piston block 308, and the sealing sleeve 309 is in contact with the inner wall of the piston box 304, and a vent hole 306 is also provided on the outer wall of the piston box 304 near the bottom. When adding the raw liquid to the mixing tank 102, the expansion and contraction of the first electric telescopic rod 307 can be used to cause the piston block 308 to be located at the bottom. When the piston 308 moves upward, the air in the piston box 304 is squeezed into the vertical box 301, and the liquid in the vertical box 301 is squeezed into the discharge cover 110 through the inclined cover 302, so that the liquid level in the mixing tank 102 rises, forcing the upper layer of liquid to flow to the bottom of the tank. When the piston moves downward, the liquid in the mixing tank 102 drops again. Through the periodic lifting action, vertical forced convection can be formed in the mixing tank 102, which can break the stratification phenomenon of light upper and heavy lower parts caused by density difference, further improve the mixing efficiency, and achieve better use effect.

[0038] As an embodiment of the present invention, please refer to Figure 7 and Figure 8The sealing mechanism includes a ring plate 401 fixedly arranged on the inner wall of the discharge cylinder 111, and support rods 402 distributed in an annular manner with equal distances are fixedly installed on the lower surface of the ring plate 401, and a mounting cylinder 403 is fixedly installed on the end of the support rod 402, and a sealing plate 405 is movably installed above the ring plate 401, and a lifting rod 404 that passes through the mounting cylinder 403 is fixedly installed on the lower surface of the sealing plate 405, and the lifting rod 404 and the mounting cylinder 403 are movably connected, and a circular ring 406 is fixedly installed on the outer wall of the lifting rod 404, and the circular ring 406 is located in the mounting cylinder 403, and a first spring 407 is sleeved on the outer side of the lifting rod 404, one end of the first spring 407 is connected to the top inner wall of the mounting cylinder 403, and the other end of the first spring 407 is connected to the circular ring 40 6, a sealing gasket 408 is fixedly installed on the lower surface of the sealing plate 405, and the sealing gasket 408 is located between the sealing plate 405 and the ring plate 401. A trigger assembly is also provided below the discharge barrel 111 for triggering the lifting rod 404 to move upward. Under the elastic force of the first spring 407, a certain downward pulling force can be applied to the sealing plate 405, so that the sealing gasket 408 at the bottom of the sealing plate 405 and the ring plate 401 fit closely, thereby playing the role of closing the discharge barrel 111. When it is necessary to release the blockage of the discharge barrel 111, the lifting rod 404 can be lifted by the trigger assembly, so that the sealing plate 405 is lifted together. At this time, the liquid can be discharged downward through the gap between the sealing plate 405 and the ring plate 401, which is very convenient to use.

[0039] As an embodiment of the present invention, please refer to Figure 7The trigger assembly includes a threaded bucket 501 that is threadedly sleeved on the outside of the discharge barrel 111. The outer wall of the discharge barrel 111 is fixedly installed with a stopper 502 that is equidistantly distributed in an annular pattern, and the top of the threaded bucket 501 is in contact with the stopper 502.

The top of the lower hopper 503 is provided with a through hole that is equidistantly distributed in an annular pattern, and a vertical rod 504 is movably installed in the through hole. The top of the vertical rod 504 is connected to the threaded bucket 501, and a stopper 505 is fixedly installed at the bottom end of the vertical rod 504. A second spring 506 is sleeved on the outer side of the vertical rod 504, one end of the second spring 506 is connected to the stopper 505, and the other end of the second spring 506 is connected to the outer wall of the lower hopper 503. The inner wall of the lower hopper 503 is also fixedly installed with a mounting rod 507 that is equidistantly distributed in an annular pattern, and a sealing block 508 is fixedly installed at the end of the mounting rod 507. The sealing block 508 The screw bucket 501 is located in the screw bucket 501, and the outer wall of the sealing block 508 fits with the inner wall of the screw bucket 501. When the mixed liquid in the mixing tank 102 needs to be discharged, the lower hopper 503 can be pushed upward, causing the second spring 506 on the outer side of the vertical rod 504 to be stretched, and the sealing block 508 will also move upward to release the blockage of the screw bucket 501. At the same time, the upward moving sealing block 508 will synchronously drive the lifting rod 404 to move upward, thereby completing the triggering operation. At this time, the liquid in the mixing tank 102 will flow down along the discharge barrel 111 into the screw bucket 501, and then flow down along the gap between the screw bucket 501 and the sealing block 508 to the lower hopper 503 and be discharged through the lower hopper 503. The operation is simple and convenient, and the sealing block 508 and the sealing plate 405 can cooperate to achieve double blocking, and the sealing performance is better.

The outer wall of the lower hopper 503 is also fixedly installed with touch rods 605 distributed in a ring at equal distances. The collection bucket for collecting the mixed liquid can be placed above the support plate 601 and aligned with the lower hopper 503. The lifting frame 604 can then be driven upward by the telescopic movement of the hydraulic cylinder 603, and the lifting frame 604 drives the supporting plate 601 upward until the top of the collecting bucket contacts the touch rod 605, which can drive the lower hopper 503 to move upward, thereby completing the automatic discharge operation of the mixed liquid, and the use effect is better.
