Description

Device for uniformly mixing electrode paste raw materials

Technical Field

The utility model relates to an electrode paste processing technology field especially relates to a device that is used for homogeneous mixing electrode paste raw materials.

Background

The raw materials of the electrode paste comprise coal powder, asphalt, coal tar and the like, wherein the asphalt and the coal tar are used as binders. The three are evenly mixed and then processed into a preset shape by a mixing and kneading forming device, and then the electrode paste is formed by roasting. Asphalt has very strong viscosity, needs to be heated and softened and then mixed, and simultaneously has very high temperature because the coal powder is formed by calcining and crushing. Theoretically, when the three components are mixed, the asphalt can maintain a good liquid phase, and finally can be mixed uniformly. However, in practice, the mixing process is generally carried out in a hopper. After the asphalt falls down and is combined with the pulverized coal, the asphalt is quickly adhered together. This results in more coal fines binding to the bitumen near the area below the bitumen feed opening and less coal fines binding to the bitumen far from the area of the bitumen feed opening. This results in a longer mixing time, and eventually may result in uneven mixing. When the mixing is not uniform, the hardness of the final product is greatly affected, thereby affecting the smelting of the subsequent alloy.
