AI Technical Summary
When used, the existing heating mixing device for preparing lithium-ion battery materials is insufficiently stirred, and the material is prone to adhere to the inner wall of the tank, resulting in uneven mixing.
A heating mixing device including a base plate, a tank body, a equipment box, a driving motor, agitating blade, an electric heating tube and a scraper is designed. The stirring leaves are cross-distributed, the electric heating pipe is located between the stirring leaves, and the scraper comes into contact with the inner wall of the tank. By driving the motor, the stirring leaves are driven to rotate and the electric heating pipe are heated, and combined with the effect of the scraper, the materials are fully mixed and heated.
Through the forward and reverse rotation of the cross-distributed stirring leaves and electric heating pipes, an irregular flow effect is generated, and the uniform mixing and heating of materials are achieved. The scraper is close to the inner wall of the tank to avoid material adhesion and ensure the improvement of mixing quality.
