Description

Technical Field

[0001] This utility model relates to the field of electrode paste preparation, and in particular to an electrode paste asphalt dispensing device. Background Technology

[0002] Electrode paste is a conductive material supplied to electric furnace equipment such as ferroalloy furnaces and calcium carbide furnaces. Also known as self-baking electrode, it relies on the heat within the submerged arc furnace for baking; therefore, matching the electrode consumption rate with the baking rate is crucial for the successful use of electrode paste. The raw materials used in producing electrode paste are primarily electrically calcined anthracite, calcined petroleum coke, and modified coal tar pitch. These various raw materials need to be mixed and then bound together during the electrode paste production process.

[0003] In the prior art, in order to increase the rationality of the raw material ratio of electrode paste, it is necessary to weigh the modified coal tar pitch to be added. However, since modified coal tar pitch is a high-viscosity organic liquid, its poor fluidity during the addition stage makes it difficult to add the modified coal tar pitch efficiently, thus affecting the preparation of electrode paste.

The asphalt weight data is displayed by the weighing instrument 12. When the amount of asphalt added meets the requirements for electrode paste preparation, the annular heater 7 at the conical part of the hopper 2 is started to heat the asphalt in the hopper 2, so that the softened asphalt can pass through several holes of the hollow plate 8 and enter the asphalt filling cylinder 6. During this process, the first motor 9 installed on the end face of the asphalt filling cylinder 6 is started, so that the asphalt is discharged from the asphalt filling cylinder 6 under the pushing action of the auger 10.
