Abstract

The invention discloses a safety monitoring system and method of an aluminum ash conveying mechanism. The system comprises an aluminum ash cooling mechanism, a conveying mechanism and an aluminum retreating mechanism which are disposed successively; wherein the conveying mechanism includes a separating and conveying mechanism and a feeding mechanism. The system also comprises a safety monitoring mechanism used for monitoring the temperature of the aluminum ash at the outlet of the separating and conveying mechanism and controlling the a driving motor to start or stop based on the temperature signals; the feeding mechanism is a conveying belt; and the separating and conveying mechanism is driven by the driving motor. The system and method disclosed by the invention achieves the advantages of compact structure, low cost, simple operation and high degree of automation, can monitor the temperature of the aluminum ash at the outlet of the separating and conveying mechanism in real time, prolongs the service life of equipment and improves using safety.

Description

technical field [0001] The invention relates to the field of recycling high-temperature aluminum ash slag, in particular to a temperature monitoring and conveying system control device and method for high-temperature aluminum ash transportation. Background technique [0002] In the electrolytic aluminum production process, the secondary recovery of refined aluminum liquid, configuration alloy and waste aluminum will produce a certain amount of aluminum ash, which contains a lot of metal aluminum, which needs to be recycled to avoid environmental damage. Pollution and great waste of energy. The recycling of aluminum ash often goes through slag removal-separation and stirring-spray cooling-aluminum ash separation-medium block collection and reprocessing, which requires high-temperature hot aluminum ash pulled out of the furnace to be stirred, separated and cooled, and then passed through the separation device The medium-sized particles of aluminum ash are separated, and then ...

AI Technical Summary

Problems solved by technology

Due to the high temperature of aluminum ash, the temperature of uncooled aluminum ash is about 400°C. At present, the conveying device of aluminum ash needs to use high temperature resistant materials. Usually, a scraper machine is used as the conveying device. The noise generated during the conveying process Larger, complex to manufacture and higher equipment cost

At the same time, during the processing of aluminum ash, the operator must send the aluminum ash cooled to a certain temperature to the processing mechanism for further processing. Once the temperature of the aluminum ash sent to the processing mechanism is too high, it will cause high-temperature corrosion and cause damage to the equipment.

In the current aluminum ash processing process, the separation, cooling and transportation of aluminum ash are controlled by different mechanisms. The temperature of aluminum ash sent to the processing mechanism needs to be controlled by the operator through the correct control of the cooling device and the experience of the operator. The cooling degree is not only complicated to operate, but also the processing efficiency of aluminum ash is low, and once the operator makes a mistake or the cooling degree is not properly controlled, it will cause great damage to the aluminum ash processing mechanism, and there are also great safety hazards in the process of operation.
