Description

Technical Field

[0001] This utility model relates to the technical field of electrolyte additive production equipment, and in particular to a liquid mixing device for electrolyte additive production. Background Technology

[0002] Electrolyte additives are a class of functional substances added to battery electrolytes. Although the amount added is usually only 1%-10% of the total electrolyte, they can significantly improve the performance of the electrolyte and play a key role in improving the overall performance of the battery. They are widely used in lithium-ion batteries and can form a dense SEI film on the surface of the negative electrode, improving the cycle stability and first charge-discharge efficiency of the battery.

[0003] Most existing liquid mixing devices for electrolyte additive production use stirring rods to mix raw materials. However, stirring rods can usually only stir the raw materials in one direction, lacking vertical stirring, resulting in uneven mixing. At the same time, some powdery and granular materials tend to settle to the bottom, further contributing to uneven mixing of raw materials. Utility Model Content

[0004] The purpose of this utility model is to provide a liquid mixing device for the production of electrolyte additives, which solves the problem that existing liquid mixing devices for the production of electrolyte additives can only perform stirring in one direction and lack stirring in the up and down direction, resulting in uneven mixing and some materials easily settling to the bottom.

[0005] To achieve the above objectives, a liquid mixing device for producing electrolyte additives is provided, comprising: a mixing tank; a motor bracket is fixedly connected to the upper end of the mixing tank; a motor is fixedly connected inside the motor bracket; a first rotating shaft is fixedly connected to the output end of the motor; a first stirring blade is fixedly connected to the outer surface of the first rotating shaft; a support rod is fixedly connected to the lower surface of the mixing tank; a discharge port is provided on the lower surface of the mixing tank; and a feed port is provided on the upper surface of the mixing tank.

[0006] The mixing tank is rotatably connected to a second rotating shaft inside. A fixed block is rotatably connected to the surface of the second rotating shaft. A guide rod is fixedly connected to the upper surface of the fixed block. A cavity is provided inside the fixed block. A first bevel gear is fixedly connected to the outer surface of the second rotating shaft. A third rotating shaft is rotatably connected to the inside of the fixed block. A second stirring blade is fixedly connected to the outer surface of the third rotating shaft. A second bevel gear is fixedly connected to the second rotating shaft. A first synchronous pulley is fixedly connected to the upper end of the second rotating shaft. A synchronous belt is rollingly connected to the outer surface of the first synchronous pulley. A second synchronous pulley is fixedly connected to the outer surface of the first rotating shaft.

[0007] According to the liquid mixing device for producing electrolyte additives, the inner surface of the cavity is slidably connected to a first bevel gear, and the inner surface of the cavity is slidably connected to a second bevel gear.

[0008] According to the liquid mixing device for producing electrolyte additives, the first bevel gear meshes with the second bevel gear, and there are two second rotating shafts distributed left and right.

[0009] According to the liquid mixing device for producing electrolyte additives, there are two fixed blocks arranged vertically, and the upper end of the guide rod is fixedly connected to the inner wall of the top of the mixing tank.

[0010] According to the liquid mixing device for producing electrolyte additives, the interior of the stirring tank is rotatably connected to the first rotating shaft.

[0011] According to the liquid mixing device for producing electrolyte additives, the upper surface of the stirring tank is slidably connected to the first synchronous wheel, and the first synchronous wheel and the second synchronous wheel are connected by a synchronous belt drive.

[0012] According to the liquid mixing device for producing electrolyte additives, a connecting ring is movably connected inside the feed inlet, and a filter screen is fixedly connected to the lower surface of the connecting ring. The inner surface of the feed inlet is in contact with the filter screen. By setting the filter screen, impurities can be intercepted during feeding, preventing impurities from entering the interior of the mixing tank.

[0013] According to the liquid mixing device for producing electrolyte additives, the number of the first stirring blades is three and they are arranged in a linear array.

[0014] The above solution has the following advantages: the second shaft is driven to rotate by the synchronous belt and synchronous pulley. When the second shaft rotates, it drives the first bevel gear to rotate. The first bevel gear drives the second bevel gear, and the second bevel gear drives the third shaft to rotate. This allows the first shaft and the third shaft to drive the two stirring blades to stir the raw materials in different directions, which improves the mixing efficiency and the uniformity of the mixture, prevents some materials from settling to the bottom, and effectively ensures the finished product.
