Description

Technical Field

[0001] This invention relates to the field of lithium battery electrolyte preparation technology, and in particular to a lithium battery electrolyte preparation apparatus and preparation process. Background Technology

[0002] The electrolyte in a lithium-ion battery is the carrier for ion transport within the battery. It is generally composed of lithium salts and organic solvents. The electrolyte plays a role in conducting ions between the positive and negative electrodes of a lithium-ion battery, ensuring that lithium-ion batteries achieve advantages such as high voltage and high specific energy. The electrolyte is generally prepared by mixing high-purity organic solvents, electrolyte lithium salts, and necessary additives under certain conditions and in certain proportions.

[0003] A search revealed Chinese patent application number CN202022427038.0, which discloses an electrolyte stirring device for micro-arc oxidation of aluminum alloys. The device includes a stirring drum, a sealing cover, a stirring mechanism, a connecting mechanism, a lifting device, a support frame, a vibration device, a support box, casters, a control panel, a safety door, a stirring motor, a coupling, a stirring shaft, stirring wheels, an upper connecting flange, connecting bolts, a lower connecting flange, a vibration motor, a mounting bracket, and a housing. The aforementioned patent's electrolyte stirring device for micro-arc oxidation of aluminum alloys has the following shortcomings:

[0004] Although the overall device completes the stirring of the electrolyte through the stirring motor and stirring rings, the method of stirring the electrolyte in the stirring tank by only two rotating stirring rings can achieve a certain degree of fusion of the various raw materials of the electrolyte. However, the stirring rings only perform stirring in the horizontal direction, and the shear force on the solution is relatively singular, resulting in relatively poor fusion quality. Even if the solution fusion is completed, its efficiency is relatively low, which increases the time cost of electrolyte preparation. Therefore, there is an urgent need for a more efficient lithium battery electrolyte preparation device and its preparation process. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a lithium battery electrolyte preparation apparatus and its preparation process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An apparatus for preparing lithium battery electrolyte includes a preparation tank. The top outer wall of the preparation tank is sealed with a top cover by a hinge, and a driving mechanism is provided at the top center of the top cover. An inlet pipe and an outlet pipe are respectively provided on the top of the top cover and one side of the bottom of the preparation tank. A stirring mechanism is provided inside the preparation tank. The stirring mechanism includes a rotating component, a vertical transmission component, and a stirring component. The rotating component is rotatably connected to the output end of the driving mechanism, the vertical transmission component is drivenly connected to one side of the rotating component, and the stirring components are arranged on both sides of the vertical transmission component.

[0008] Preferably, the rotating assembly includes a top rod, a connecting shaft, a rotating shaft, a bottom ring, a stabilizing disc, a connecting rod, an arc-shaped guide ring, and a connecting plate;

[0009] A rotating shaft is connected to the output end of the drive mechanism via a coupling;

[0010] The connecting shaft is threaded onto the circumference of the rotating shaft;

[0011] Two push rods are respectively set on both sides of the connecting shaft.

[0012] Furthermore: the two connecting rods are respectively disposed on one side of the bottom of the two top rods, and the middle section of the two connecting rods has a notch;

[0013] The arc-shaped guide ring and the connecting plate are respectively set on the two notches.

[0014] Based on the aforementioned scheme: the bottom ring is welded to the center of the bottom of the preparation barrel;

[0015] The stabilizing disk is rotatably connected to the inner circumference of the bottom ring, and the stabilizing disk and the bottom ring form a sliding rotational fit. The bottom ends of the two connecting rods are respectively connected to the top two sides of the stabilizing disk through threads.

[0016] A preferred embodiment of the aforementioned scheme is that the vertical transmission assembly includes a side wheel, a rotating rod, a fixed wheel, a rotating wheel, and a transmission bar.

[0017] A rotating wheel is located at the bottom end of the rotating shaft;

[0018] The rotating rod is threaded through and connected to the center of the connecting plate;

[0019] Side wheels, two side wheels are rotatably connected to both ends of the rotating rod, and the stirring assembly is fixedly connected to one side of the side wheels;

[0020] The top center outer wall of the fixed wheel and the stabilizing plate has a fixing hole, and a fixing bearing is installed in the fixing hole. A support rod is inserted into the fixing bearing, and the bottom outer wall of the support rod is set on the bottom center inner wall of the preparation barrel. The fixed wheel is set on the top circumference of the support rod.

[0021] As a further aspect of the present invention: the transmission bar is sleeved on the circumference of the two side wheels, the fixed wheel and the rotating wheel, and the transmission bar forms a transmission engagement with the two side wheels, the fixed wheel and the rotating wheel.

[0022] Meanwhile, the stirring assembly includes a friction ball, a mounting ring, a socket, a stirring block, a rotating groove, and a guide hole;

[0023] The mounting ring has a groove on the outer circumference of the side wheel, and the mounting ring is welded to one side of the circumference of the side wheel.

[0024] The sockets, three or more, are respectively opened on the circumference of the mounting ring.

[0025] As a preferred embodiment of the present invention: the stirring blocks are respectively inserted into the insertion hole and the slot on one side;

[0026] The rotating groove and the guide hole are located on one side of the mixing block, and the rotating groove is located inside the guide hole.

[0027] The friction ball is rotatably connected to the rotating groove via a guide shaft.

[0028] Meanwhile, a fixed shaft is provided on the outer wall of the top center of the fixed wheel, and a frustum is fixed to the outer wall of the fixed shaft by a support plate. A snap ring is welded to the top circumference of the frustum, and an annular groove is opened in the inner ring of the snap ring. An insertion interface is opened on one side of the annular groove, and a filter ring is inserted into the insertion interface. Buffer protrusions are provided at equal intervals on the inner ring of the frustum.

[0029] A process for preparing a lithium battery electrolyte includes the following steps:

[0030] S1: Various raw materials of electrolyte are introduced into the preparation tank through the inlet pipe. The drive mechanism is started, which drives the rotating shaft to rotate. Through the connecting shaft, the top rod and the connecting rod at the bottom rotate. The rotating connecting rod drives the stabilizing plate to rotate and slide in the bottom ring, completing the horizontal circular motion of the side wheel around the rotating shaft, which promotes the horizontal rotation of the stirring component on one side of the side wheel.

[0031] S2: When the rotating wheel is driven to rotate by the rotating shaft, the two side wheels are driven to rotate on their own axis while performing horizontal circular motion through the transmission bar, thus realizing a rotational motion parallel to the axis of the rotating shaft.

[0032] S3: When the side wheel rotates, it can effectively drive the mounting ring to rotate. The rotating mounting ring drives the stirring block on its circumference to rotate, which promotes the separation of the solution. At the same time, the friction ball in the guide hole of the stirring block can effectively rotate and contact the solution, accelerating the fusion between the raw material liquids.

[0033] S4: When the solution is introduced through the frustum cylinder, the solution divided by the side wheel will hit the filter ring, thus completing the filtration of the solution.

[0034] The beneficial effects of this invention are as follows:

[0035] 1. A lithium battery electrolyte preparation apparatus and its preparation process, during operation, various raw material solutions of the electrolyte are introduced into the preparation tank through the inlet pipe. Simultaneously, the drive mechanism is activated, driving the rotating shaft to rotate, which in turn drives the top rod and the connecting rod at the bottom to rotate through the connecting shaft. At this time, the rotating connecting rod drives the stabilizing disk to rotate and slide within the bottom ring, completing the horizontal circular motion of the side wheel around the rotating shaft. This promotes the horizontal rotation of the stirring component on one side of the side wheel. At the same time, when the rotating wheel is driven to rotate by the rotating shaft, the two side wheels are driven to rotate simultaneously through the transmission bar, thus achieving a rotational motion parallel to the axis of the rotating shaft. This improves the shear force of the stirring component on the solution, ensures the quality of solution fusion, and also improves the efficiency of electrolyte preparation, reducing the preparation time cost of the electrolyte.

[0036] 2. The lithium battery electrolyte preparation device and its preparation process, when the side wheel rotates, can effectively drive the mounting ring to rotate, and the rotating mounting ring drives the stirring block on its circumference to rotate, thereby effectively playing the role of cutting the solution. At the same time, the friction ball in the guide hole of the stirring block can effectively rotate and contact the solution, increasing the friction between it and the solution, thereby improving the activity of fusion in the solution and accelerating the preparation speed of the electrolyte.

[0037] 3. The apparatus and process for preparing lithium battery electrolyte, when the solution is introduced through the frustum cylinder, the solution divided by the side wheel will impact the filter ring to complete the filtration of the solution. At the same time, before this, the filter ring is inserted from the arc-shaped guide ring into the annular groove of the snap ring to complete the installation and removal of the filter ring, which facilitates the cleaning and replacement of the filter ring.

[0045] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0046] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0047] Example 1:

[0048] An apparatus for preparing a lithium battery electrolyte, such as... Figure 1-6 As shown, the preparation tank includes a preparation tank 1. The top outer wall of the preparation tank 1 is sealed with a top cover 5 by a hinge. A drive mechanism 4 is provided at the top center of the top cover 5. The top of the top cover 5 and the bottom side of the preparation tank 1 are respectively connected by a liquid inlet pipe 3 and a liquid outlet pipe 2 through threads. A stirring mechanism is provided inside the preparation tank 1. The stirring mechanism includes a rotating component, a vertical transmission component and a stirring component. The rotating component is rotatably connected to the output end of the drive mechanism 4. The vertical transmission component is drivenly connected to one side of the rotating component. The stirring component is provided on both sides of the vertical transmission component.

[0049] The rotating assembly includes a top rod 6, a connecting shaft 7, a rotating shaft 8, a bottom ring 11, a stabilizing disk 12, a connecting rod 13, an arc-shaped guide ring 14, and a connecting plate 16;

[0050] Rotating shaft 8 is connected to the output end of drive mechanism 4 via a coupling;

[0051] Connecting shaft 7 is threaded onto the circumference of rotating shaft 8;

[0052] The two push rods 6 are respectively fixed to both sides of the connecting shaft 7 by bolts;

[0053] Connecting rod 13, two connecting rods 13 are respectively threaded to the bottom side of two push rods 6, and the middle section of the two connecting rods 13 has a notch;

[0054] The arc-shaped guide ring 14 and the connecting plate 16 are respectively connected to the two notches by bolts;

[0055] Bottom ring 11, which is welded to the center of the bottom of preparation barrel 1;

[0056] The stabilizing disk 12 is rotatably connected to the inner circumference of the bottom ring 11, and the stabilizing disk 12 and the bottom ring 11 form a sliding rotational fit. The bottom ends of the two connecting rods 13 are respectively connected to the top two sides of the stabilizing disk 12 by threads.

[0057] The vertical transmission assembly includes a side wheel 10, a rotating rod 15, a fixed wheel 17, a rotating wheel 19, and a transmission bar 20;

[0058] Rotating wheel 19 is threadedly connected to the bottom end of rotating shaft 8;

[0059] Rotating rod 15 is threadedly connected to the center of connecting plate 16;

[0060] Side wheels 10, two side wheels 10 are respectively rotatably connected to the two ends of the rotating rod 15, and the stirring assembly is fixedly connected to one side of the side wheels 10;

[0061] The top center outer wall of the fixed wheel 17 and the stabilizing disk 12 has a fixing hole, and a fixing bearing is connected to the fixing hole by a thread. A support rod is inserted into the fixing bearing, and the bottom outer wall of the support rod is connected to the bottom center inner wall of the preparation barrel 1 by a thread. The fixed wheel 17 is connected to the top circumference of the support rod by a thread.

[0062] The transmission bar 20 is sleeved on the circumference of the two side wheels 10, the fixed wheel 17 and the rotating wheel 19, and the transmission bar 20 forms a transmission engagement with the two side wheels 10, the fixed wheel 17 and the rotating wheel 19.

[0063] During operation, various raw materials for the electrolyte are introduced into the preparation tank 1 through the inlet pipe 3. Simultaneously, the drive mechanism 4 is activated, which drives the rotating shaft 8 to rotate. This, in turn, drives the top rod 6 and its bottom connecting rod 13 to rotate via the connecting shaft 7. At this time, the rotating connecting rod 13 drives the stabilizing disk 12 to rotate and slide within the bottom ring 11, completing the horizontal circular motion of the side wheel 10 around the rotating shaft 8. This promotes the horizontal rotation of the stirring assembly on one side of the side wheel 10. At the same time, when the rotating wheel 19 is driven to rotate by the rotating shaft 8, the transmission bar 20 drives the two side wheels 10 to rotate simultaneously while performing horizontal circular motion, thus achieving a rotational motion parallel to the axis of the rotating shaft 8. This improves the shear force of the stirring assembly on the solution, ensures the quality of solution fusion, and also improves the efficiency of electrolyte preparation, reducing the preparation time and cost of the electrolyte.

[0064] To improve the activity of the solution during mixing; such as Figure 2 and Figure 5 As shown, the stirring assembly includes a friction ball 9, a mounting ring 21, a socket 22, a stirring block 23, a rotating groove 24, and a guide hole 25;

[0065] Mounting ring 21, the outer circumferential wall of side wheel 10 has a groove, and mounting ring 21 is welded to one side circumference of side wheel 10;

[0066] Socket 22, three or more sockets 22 are respectively opened on the circumference of the mounting ring 21;

[0067] The stirring block 23 is inserted into the insertion hole 22 and the slot on one side respectively;

[0068] The rotating groove 24 and the guide hole 25 are located on one side of the stirring block 23, and the rotating groove 24 is located inside the guide hole 25.

[0069] Friction ball 9 is rotatably connected to the rotating groove 24 via a guide shaft;

[0070] When the side wheel 10 rotates, it can effectively drive the mounting ring 21 to rotate. The rotating mounting ring 21 drives the stirring block 23 on its circumference to rotate, thereby effectively dividing the solution. At the same time, the friction ball 9 in the guide hole 25 inside the stirring block 23 can effectively rotate and contact the solution, increasing the friction between it and the solution, thereby improving the activity of solution fusion and accelerating the preparation speed of electrolyte.

[0071] To facilitate filtration of the solution and improve its purity; such as Figure 3 and Figure 6As shown, the outer wall of the top center of the fixed wheel 17 is fixed with a fixed shaft 29 by bolts, and the outer wall of the fixed shaft 29 is fixed with a frustum cylinder 18 by a support plate. A snap ring 26 is welded to the top circumference of the frustum cylinder 18, and the inner ring of the snap ring 26 has an annular groove 27. An insertion interface is opened on one side of the annular groove 27, and a filter screen ring is inserted into the insertion interface. The inner ring of the frustum cylinder 18 is provided with buffer protrusions 28 distributed at equal intervals. When the solution is introduced through the frustum cylinder 18, the solution divided by the side wheel 10 will hit the filter screen ring to complete the filtration of the solution. At the same time, before this, the filter screen ring is inserted from the arc-shaped guide ring 14 into the annular groove 27 of the snap ring 26 to complete the installation and removal of the filter screen ring, which facilitates the cleaning and replacement of the filter screen ring.

[0072] In this embodiment, various raw materials of electrolyte are introduced into the preparation tank 1 through the inlet pipe 3. At the same time, the drive mechanism 4 is started, which drives the rotating shaft 8 to rotate. Through the connecting shaft 7, the top rod 6 and the connecting rod 13 at the bottom are rotated. At this time, the rotating connecting rod 13 drives the stabilizing disk 12 to rotate and slide within the bottom ring 11, completing the horizontal circular motion of the side wheel 10 around the rotating shaft 8. This promotes the horizontal rotation of the stirring assembly on one side of the side wheel 10.

[0073] When the rotating wheel 19 is driven to rotate by the rotating shaft 8, the two side wheels 10 are driven to rotate on their own axis while performing horizontal circular motion through the transmission bar 20, thereby realizing a rotational motion parallel to the axis of the rotating shaft 8.

[0074] When the side wheel 10 rotates, it can effectively drive the mounting ring 21 to rotate. The rotating mounting ring 21 drives the stirring block 23 on its circumference to rotate, which promotes the separation of the solution. At the same time, the friction ball 9 in the guide hole 25 inside the stirring block 23 can effectively rotate and contact the solution, accelerating the fusion between the raw material liquids.

[0075] When the solution is introduced through the frustum cylinder 18, the solution divided by the side wheel 10 will hit the filter ring, thus completing the filtration of the solution.

[0078] S1: Various raw materials of electrolyte are introduced into preparation tank 1 through inlet pipe 3. Drive mechanism 4 is started. Drive mechanism 4 drives rotating shaft 8 to rotate, and through connecting shaft 7, drives top rod 6 and bottom connecting rod 13 to rotate. The rotating connecting rod 13 drives stabilizing disk 12 to rotate and slide in bottom ring 11, completing the horizontal circular motion of side wheel 10 around rotating shaft 8, promoting the horizontal rotation of stirring component on one side of side wheel 10.

[0079] S2: When the rotating wheel 19 is driven to rotate by the rotating shaft 8, the two side wheels 10 are driven to rotate on their own axis while performing horizontal circular motion through the transmission bar 20, thus realizing a rotational motion parallel to the axis of the rotating shaft 8.

[0080] S3: When the side wheel 10 rotates, it can effectively drive the mounting ring 21 to rotate. The rotating mounting ring 21 drives the stirring block 23 on its circumference to rotate, which promotes the separation of the solution. At the same time, the friction ball 9 in the guide hole 25 inside the stirring block 23 can effectively rotate and contact the solution, accelerating the fusion between the raw material liquids.

[0081] S4: When the solution is introduced through the frustum cylinder 18, the solution divided by the side wheel 10 will hit the filter ring, thus completing the filtration of the solution.
