Embodiment Construction

[0027] Such as figure 1 Shown: a method of preheating and compounding prebaked anode paste for electrolytic aluminum, adopting the method of heating material proportioning, and the steps are as follows:

[0028] a. Store raw materials with different particle sizes in different preheating silos 3 through fixed storage silos;

[0029] b. There is a heating device in the pre-heating bin 3, which pre-heats the raw materials to ensure the temperature of the materials at about 180°C;

[0030] c. Each heating bin 3 is equipped with a metering device, and the discharge volume is controlled by subtraction measurement, so that the feeding accuracy is within 5‰; the raw materials in each heating bin 3 can be discharged 3 to 4 times, after When the metering device detects that the discharge volume is less than the set value, the star-shaped discharge valve 2 on the upper part of the heating bin 3 is activated, and the material is discharged into it until the required set value is reached...

Abstract

The invention discloses a method and a system for preheating ingredients of prebaked anode paste for electrolytic aluminium. The method comprises the following steps: storing raw materials with different granularity in different preheating bins (3) respectively through a fixing material storage bin (1) by adopting a hot material matching mode, and preheating the materials to ensure that the temperature of the materials is about 180 DEG C; controlling the discharge amount through subtraction metering, and discharging the raw material with different granularity in each preheating bin (3) according to the matching requirement; and transporting the discharged raw materials to different kneading pots through a spiral conveyor (4) set and feeding thermal insulation pipelines, and stirring the raw materials for between 35 and 40 minutes. The method and the system can monitor the performing situation of each action and adjust parameters of each action at any time in the equipment operation process; and compared with the conventional production mode, the method saves time, improves production efficiency, and changes the conventional cool material matching mode to enable the matching to be more accurate and the effect to be better, thereby greatly improving the quality of a finished product block.

Description

technical field [0001] The invention belongs to the technical field of electrolytic aluminum heating and proportioning, and in particular relates to a method and system for preheating and proportioning prebaked anode paste for electrolytic aluminum. Background technique [0002] Carbon anode for electrolytic aluminum is a material that consumes a lot in the production process of electrolytic aluminum, commonly known as prebaked anode. With the rapid development of the domestic electrolytic aluminum industry in the past two years, the demand for electrolytic aluminum for prebaked anodes has also doubled. For carbon plants, meeting market demand has become the foundation of development. Increasing production capacity, improving product quality, and reducing costs are more important to the development of carbon plants. [0003] In the process of pre-cultivated anode production, the ratio and kneading of raw materials are very important processes. The error of raw material rati...
