Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery separator production technology, specifically a slurry mixing device for battery separator production. Background Technology
[0002] In the production process of battery separators, uniform mixing of slurry is a key step to ensure the performance of battery separators. At present, traditional slurry mixing devices have many shortcomings in practical applications. On the one hand, the mixing of slurry is often insufficient, especially in the bottom area of the mixing tank, where slurry is prone to settling, resulting in uneven mixing, which in turn affects the quality and performance of battery separators.
[0003] On the other hand, during the feeding process of solid raw materials, traditional equipment lacks an effective dispersing and conveying mechanism. Solid raw materials are prone to clumping and accumulation and blockage in the feeding channel, making it impossible for solid raw materials to mix smoothly and evenly with liquid raw materials, reducing production efficiency and product quality stability. In addition, traditional mixing devices have poor sealing performance in their structural design, and slurry is prone to leakage at the connection of rotating parts, which not only wastes raw materials but may also affect the normal operation of mixing and even pose safety hazards.
[0004] To address these issues, this invention provides a slurry mixing device for battery separator production. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides a slurry mixing device for battery separator production, which solves the aforementioned problems.

[0008] Preferably, a fixing rod is fixedly installed at the bottom of the mixing tank, and a second bevel gear is fixedly installed at the top of the fixing rod. The fixing rod movably passes through the bottom wall of the rotating block. A first bevel gear is fixedly installed at the inner end of the second rotating rod. The first bevel gear is located inside the rotating block, and all of the first bevel gears mesh with the outer side of the second bevel gear.
[0009] Preferably, a sealing ring is fixedly installed at the connection between the second rotating rod and the rotating block, and at the connection between the fixed rod and the rotating block.

[0013] This invention provides a slurry mixing device for battery separator production. Compared with the prior art, it has the following advantages: 1. The slurry mixing device for battery separator production uses a first motor to drive the first rotating rod and the first stirring blade to rotate, causing the slurry to flow in a ring. At the same time, the rotating block drives the second rotating rod and the second stirring blade to perform a compound motion of revolution and rotation, forming a complex flow trajectory. This effectively prevents the slurry from settling to the bottom and ensures that the slurry is fully and evenly mixed in the mixing tank, thereby improving the quality of the slurry used in battery separator production and laying a good foundation for the performance of the subsequent battery separator.
[0014] 2. In this slurry mixing device for battery separator production, the second motor drives the third rotating rod to rotate in the solid feeding assembly. The third stirring blades perform preliminary mixing and dispersing of the solid raw materials to prevent clumping. The spiral conveying blades then stably transport the dispersed raw materials into the mixing tank. The two work together to keep the solid raw materials in a loose state during the feeding process, preventing them from accumulating and clogging in the connecting pipe. This ensures that the solid and liquid raw materials can be fully mixed, improving production efficiency and product quality stability. Attached Figure Description

[0019] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.
[0020] Reference Figures 1 to 5This application provides a slurry mixing device for battery separator production, including a mixing tank 1. A mixing component 2 is arranged inside the mixing tank 1. A solid feeding component 3 is arranged on the top of the mixing tank 1. A controller 4 is fixedly installed on the right side of the mixing tank 1. A liquid feeding pipe 5 is fixedly installed on the top of the mixing tank 1. A discharge valve 6 is fixedly installed on the bottom left side of the mixing tank 1. The mixing component 2 includes a first rotating rod 22, which is rotatably connected to the inner bottom of the mixing tank 1. A first stirring blade 23 is fixedly installed on the outer side of the first rotating rod 22. A rotating block 24 is fixedly installed at the bottom of the first rotating rod 22. A second rotating rod 25 is rotatably connected to the inside of both the left and right sides of the rotating block 24. A second stirring blade 26 is fixedly installed on the outer side of the second rotating rod 25.
[0021] A first motor 21 is fixedly installed on the top of the mixing tank 1. The output end of the first motor 21 movably passes through the top wall of the mixing tank 1 and is fixedly connected to the first rotating rod 22. A fixed rod 28 is fixedly installed on the bottom of the mixing tank 1. A second bevel gear 29 is fixedly installed on the top of the fixed rod 28. The fixed rod 28 movably passes through the bottom wall of the rotating block 24. A first bevel gear 27 is fixedly installed on the inner end of the second rotating rod 25. The first bevel gear 27 is located inside the rotating block 24 and meshes with the outer side of the second bevel gear 29. Sealing rings are fixedly installed at the connection between the second rotating rod 25 and the rotating block 24, and at the connection between the fixed rod 28 and the rotating block 24. The sealing rings are embedded inside the rotating block 24 and sleeved on the outer side of the second rotating rod 25 and the fixed rod 28.
[0022] In this embodiment, after the first motor 21 starts, its output end drives the first rotating rod 22 to rotate, and the first stirring blade 23 on the outer side of the first rotating rod 22 rotates accordingly, performing preliminary stirring of the slurry in the mixing tank 1, causing the slurry to generate a ring flow. At the same time, the rotating block 24 at the bottom of the first rotating rod 22 also rotates. The second rotating rod 25, which is rotatably connected to the left and right sides of the rotating block 24, is equipped with second stirring blades 26 on its outer side. Since the second bevel gear 29 fixed at the top of the fixed rod 28 meshes with the first bevel gear 27 at the inner end of the second rotating rod 25, when the rotating block 24 rotates, it will drive the first bevel gear 27 to revolve around the second bevel gear 29. At the same time, the first bevel gear 26... 7 will also rotate, which will cause the second rotating rod 25 to drive the second stirring blade 26 to not only revolve around the first rotating rod 22 under the drive of the rotating block 24, but also rotate and stir itself. This compound motion mode can make the slurry form a complex flow trajectory in the mixing tank 1, fully agitate the slurry at the bottom, effectively prevent the slurry from settling to the bottom during the stirring process, and ensure that the slurry is mixed evenly. In addition, sealing rings are installed at the connection between the second rotating rod 25 and the rotating block 24, and between the fixed rod 28 and the rotating block 24. The sealing rings are embedded inside the rotating block 24 and sleeved on the outside of the second rotating rod 25 and the fixed rod 28, effectively preventing slurry leakage and ensuring the normal operation of the stirring work.
[0023] Reference Figures 1 to 5 In one aspect of this embodiment, the solid feeding assembly 3 includes a feeding hopper 31, a connecting pipe 32 is fixedly installed at the bottom of the feeding hopper 31, the connecting pipe 32 is fixedly installed at the top of the mixing tank 1, a horizontal plate 33 is fixedly installed at the top of the feeding hopper 31, a third rotating rod 34 is fixedly installed at the bottom of the horizontal plate 33, and a third stirring blade 36 is fixedly installed on the outer side of the third rotating rod 34.
[0024] A second motor 35 is fixedly installed on the top of the horizontal plate 33. The output end of the second motor 35 moves through the interior of the horizontal plate 33 and is fixedly connected to the third rotating rod 34. A spiral conveying blade 37 is fixedly installed at the bottom of the third rotating rod 34. The spiral conveying blade 37 is located inside the connecting pipe 32.
[0025] In this embodiment, after the second motor 35 starts, its output end drives the third rotating rod 34 to rotate. The third stirring blade 36 on the outside of the third rotating rod 34 performs preliminary stirring and dispersing on the solid raw material entering the feeding hopper 31 to prevent the raw material from clumping. At the same time, the spiral conveying blade 37 at the bottom of the third rotating rod 34 is located inside the connecting pipe 32. As the third rotating rod 34 rotates, the spiral conveying blade 37 can stably convey the pre-stirred solid raw material along the connecting pipe 32 into the mixing tank 1. The stirring action of the third stirring blade 36 and the stable conveying action of the spiral conveying blade 37 work together to keep the solid raw material in a loose state during the feeding process, and it will not accumulate and block in the connecting pipe 32. This ensures that the solid raw material can enter the mixing tank 1 smoothly and evenly and be fully mixed with the liquid raw material.
[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0027] Working Principle: After the first motor 21 starts, its output end drives the first rotating rod 22 to rotate. The first stirring blade 23 on the outer side of the first rotating rod 22 rotates accordingly, initially stirring the slurry in the mixing tank 1, causing the slurry to flow in a ring. At the same time, the rotating block 24 at the bottom of the first rotating rod 22 also rotates. The second rotating rod 25, which is rotatably connected to the left and right sides of the rotating block 24, is equipped with second stirring blades 26 on its outer side. Since the second bevel gear 29 fixed at the top of the fixed rod 28 meshes with the first bevel gear 27 at the inner end of the second rotating rod 25, when the rotating block 24 rotates, it will drive the first bevel gear 27 to revolve around the second bevel gear 29. At the same time, the first bevel gear 27 will also rotate on its own axis. This causes the second rotating rod 25 to drive the second stirring blade 26 to not only revolve around the first rotating rod 22 under the drive of the rotating block 24, but also to rotate and stir itself. This compound motion mode enables the slurry to form a complex flow trajectory in the mixing tank 1, fully stirring the slurry at the bottom, effectively preventing the slurry from settling to the bottom during the stirring process, and ensuring that the slurry is mixed evenly. In addition, sealing rings are installed at the connection points between the second rotating rod 25 and the rotating block 24, and between the fixed rod 28 and the rotating block 24. The sealing rings are embedded inside the rotating block 24 and sleeved on the outside of the second rotating rod 25 and the fixed rod 28, effectively preventing slurry leakage and ensuring the normal operation of the mixing work. After the second motor 35 is started, its output end drives the third rotating rod 34 to rotate. The third stirring blade 36 on the outside of the third rotating rod 34 performs preliminary stirring and dispersing on the solid raw materials entering the feeding hopper 31 to avoid the raw materials from clumping. At the same time, the spiral conveying blade 37 at the bottom of the third rotating rod 34 is located inside the connecting pipe 32. As the third rotating rod 34 rotates, the spiral conveying blade 37 can stably convey the pre-stirred solid raw materials along the connecting pipe 32 to the mixing tank 1. The stirring action of the third stirring blade 36 and the stable conveying action of the spiral conveying blade 37 work together to keep the solid raw materials in a loose state during the feeding process, and they will not accumulate and block in the connecting pipe 32, ensuring that the solid raw materials can enter the mixing tank 1 smoothly and evenly and be fully mixed with the liquid raw materials.
