AI Technical Summary

Technical Problem

Existing methods for mixing electrolytic aluminum covering materials suffer from problems such as segregation, uneven mixing, low automation, and inability to accurately control the proportions, which affect the thermal insulation performance of the covering materials for electrolytic cells.

Method used

The material is precisely proportioned and uniformly mixed by using bin one and bin two to connect to the cover material rotary valve and the alumina rotary valve respectively. The operating speed of the discharge valve and the design of the diversion valve are controlled by the frequency converter. The material is then mixed in layers and segments using a non-powered mixing bin, and finally uniformly delivered on a horizontal belt conveyor.

Benefits of technology

It achieves precise proportioning and uniform mixing of electrolytic aluminum covering material, solves segregation and stratification phenomena, improves automation, reduces labor costs and time, and ensures the thermal insulation performance of electrolytic cell covering material.

Abstract

The present application belongs to the technical field of material mixing and distribution, and particularly relates to an electrolytic aluminum covering material precise proportioning automatic mixing device and method, which comprises a bin one and a bin two, the bottom end of the bin one is connected with a plurality of covering material star-shaped discharge valves controlled by a frequency converter, the plurality of covering material star-shaped discharge valves are arranged in series along the vertical direction; the bottom end of the bin two is connected with an aluminum oxide star-shaped discharge valve controlled by a frequency converter, the bottom end of the covering material star-shaped discharge valve located at the bottom side is connected with a main pipe and a non-powered mixing bin, the bottom end of the aluminum oxide star-shaped discharge valve is provided with a flow divider, and the flow divider is connected with the main pipe, the covering material star-shaped discharge valve and a plurality of branch pipes. The discharging amount is controlled by changing the running speed of the star-shaped discharge valve, so that the accurate proportioning of various materials is freely switched, the materials are accurately and fully mixed in proportion, and the segregation and stratification phenomena generated in the mixing and conveying process of the materials are completely solved.
