Description

Technical Field

[0001] This utility model relates to the field of battery raw material mixing and stirring technology, specifically to a device for mixing and stirring battery raw materials. Background Technology

[0002] Battery raw materials mainly include lithium ore, phosphate ore, and nickel ore. Lithium ore is one of the important raw materials for battery manufacturing. It mainly exists in the form of spodumene and lepidolite. Lithium extracted from lithium ore is a key raw material for manufacturing lithium batteries. Lithium batteries are widely used in various electronic devices and electric vehicles. Phosphate ore is an important raw material for lithium iron phosphate batteries. As the demand for lithium iron phosphate batteries increases, the price of phosphate ore also rises. Lithium iron phosphate batteries are favored for their high energy density, long cycle life, and good safety. Because high nickel content is the future development direction of power batteries, nickel plays an important role in improving battery energy density and range performance.

[0003] However, existing battery material mixing and stirring devices often result in large particles and clumps in the battery materials due to insufficient crushing or compression and moisture during storage. This leads to uneven mixing, wasting materials and increasing costs. Therefore, we propose a battery material mixing and stirring device. Utility Model Content

[0004] The purpose of this utility model is to provide a battery raw material mixing and stirring device, which has the advantages of crushing and screening raw materials. It solves the problem that in the use of existing battery raw material mixing and stirring devices, due to reasons such as imprecise crushing of battery raw materials or compression and moisture during stacking, large particles and clumps of battery raw materials are formed. As a result, the mixing and stirring of battery raw materials is uneven due to large particles and clumps, which wastes materials and increases costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A mixing and stirring device for battery raw materials, comprising a mixing tank and a motor, wherein a first stirring rod is fixedly installed at the output end of the motor, the left end of the first stirring rod is movably connected to the lower end of the left side of the mixing tank via a bearing, a plurality of first stirring blades distributed at equal angles are fixedly installed on the surface of the first stirring rod, a first stirring pulley is fixedly installed on the left end of the first stirring rod, a crushing rod is movably connected to the upper end of the mixing tank via a bearing, a plurality of crushing blades distributed at equal angles are fixedly installed on the surface of the crushing rod, a first crushing pulley is fixedly installed on the left end of the crushing rod, a second crushing pulley is fixedly installed on the right end of the crushing rod, a transmission rod is movably connected to the middle end of the right side of the mixing tank via a bearing, a pulley is fixedly installed on the right end of the transmission rod, a first belt is sleeved on the outer side of the pulley and the second crushing pulley, a gear is fixedly installed on the left end of the transmission rod, and an annular groove is fixedly installed on the upper ends of both sides of the inner cavity of the mixing tank, a sieve cylinder is movably connected in the annular groove, and an annular toothed plate meshing with the gear is fixedly installed on the right end of the outer surface of the sieve cylinder.

[0006] Preferably, support columns are fixedly installed around the bottom of the mixing tank, and anti-vibration pads are fixedly installed at the bottom of the support columns.

[0007] Preferably, a reinforcing support plate is fixedly connected to the lower right side of the outer surface of the mixing tank, and the bottom of the motor is fixedly installed on the top of the reinforcing support plate.

[0008] Preferably, the lower end of the mixing tank is movably connected to a second stirring rod via a bearing, and the number of the second stirring rods is two.

[0009] Preferably, a plurality of second stirring blades are fixedly installed on the surface of the second stirring rod at equal angles, and a second stirring pulley is fixedly installed on the left end of the second stirring rod.

[0010] Preferably, a second belt is fitted around the outer sides of the first crushing pulley, the first stirring pulley, and the second stirring pulley.

[0011] Preferably, a discharge valve is fixedly installed at the lower end of the front surface of the mixing tank via a pipe, and a feed hopper is fixedly installed at the upper end of the right side of the mixing tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a motor to drive a first stirring rod to rotate, which in turn drives a first stirring pulley to rotate. Simultaneously, the rotation of the first stirring pulley, along with the rotation of the second stirring pulley, the first crushing pulley, the crushing rod, the crushing blade, the second crushing pulley, the first belt, and the pulley, are all driven to rotate by a second belt. Then, the pulley drives a ring-shaped toothed plate meshing with a gear to rotate via a rotating rod. The ring-shaped toothed plate causes the screening cylinder to move within an annular groove, thereby enabling the crushing and screening of battery raw materials in the screening cylinder, avoiding material waste and reducing operating costs.

[0014] 2. This utility model, through the setting of the second stirring rod, can uniformly stir areas that the first stirring rod cannot reach. The rotation of the second belt drives the rotation of the second stirring pulley and the second stirring rod. At the same time, the second stirring blades on the surface of the second stirring rod uniformly stir the battery materials at the bottom of the mixing tank, thus avoiding the situation where the battery materials cannot be fully and evenly stirred.
