Description

Technical Field

[0001] The utility model relates to the technical field of electrode paste production, in particular to a rotary extrusion rapid forming device for electrode paste. Background Art

[0002] Electrode paste is a conductive material supplied to ferroalloy furnaces and calcium carbide furnaces. Currently, the raw materials used in the production of electrode paste are basically ordinary calcined anthracite, metallurgical coke powder, and medium-temperature coal tar. The traditional electrode paste manufacturing process includes crushing, grinding, screening, batching, mixing, and the final molding process.

[0003] After searching, it was found that the publication number is CN211616734U, and the name is an electrode paste extrusion molding device. The application raises the problem of low efficiency of electrode paste extrusion molding in the molding process of existing equipment. By setting an extrusion roller, the electrode paste in the feeding barrel is initially extruded and fed by the spiral conveying blade, and the second motor is turned on to drive the two gears to rotate slowly, so that the two extrusion rollers rotate slowly, and the electrode paste falls into the extrusion groove of the corresponding extrusion roller. When the two extrusion rollers rotate slowly, the corresponding extrusion groove and the extrusion block engage with each other, so that the extrusion block extrudes the electrode paste in the extrusion groove. However, when this application is used, the spiral conveying blade adds the electrode paste between the extrusion rollers in batches, and the addition is not accurate and uniform, which can easily cause some electrode paste raw materials to leak and need to be collected and re-extruded, affecting work efficiency. At the same time, the extrusion roller unloading structure is too complicated, not simple and efficient enough, and further improvements can be made.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

At the same time, the servo motor 7 drives the feeding auger 17 to rotate for accurate feeding, which can accurately feed the electrode paste into the inner wall of the forming cylinder 12, significantly reducing the leakage phenomenon. At the same time, by controlling the working time of the servo motor 7, the rotation angle of the feeding auger 17 can be controlled, thereby changing the weight of the electrode paste entering the forming cylinder 12, and changing the thickness of the electrode paste after molding. The feeding is accurate and reliable, and the production precision and production efficiency are improved.
