AI Technical Summary

Technical Problem

In traditional Bayer process alumina production sedimentation systems, the separation sedimentation tanks cannot operate stably when their condition deteriorates. Cleaning and maintenance are inconvenient, which can easily lead to the sedimentation system running muddy, reducing production, or stalling, thus affecting system stability.

Method used

By setting up feed pipes, feed control valves, and feed control valves, the distribution of leached slurry can be regulated; when the tank condition deteriorates, the feed pipeline can be adjusted to ensure that the separation and settling tank with deteriorated tank condition has sufficient processing time and space; and by setting up spare feed pipes and spare separation and settling tanks, stable production and convenient maintenance can be achieved when the tank condition deteriorates.

Benefits of technology

This has enabled stable production operation of the separation settling tank, extended the processing time of the washing settling tank, ensured the stable operation and convenient maintenance of the settling system, and avoided the phenomena of runaway sedimentation, reduced production, and stalled operation.

Abstract

The utility model discloses a system capable of ensuring stable operation of a settling system in aluminum oxide production, which comprises a No.1 separating and settling tank and a No.2 separating and settling tank, the No.1 separating and settling tank and the No.2 separating and settling tank are respectively connected with a feed pipe, a material mixing pipe is connected between the feed pipe of the No.1 separating and settling tank and the feed pipe of the No.2 separating and settling tank, and the feed pipe of the No.1 separating and settling tank is connected with the feed pipe of the No.2 separating and settling tank. A material channeling control valve is arranged on the material channeling pipe, and feeding control valves are respectively arranged on the feeding pipe between the material channeling pipe and the No.1 separating and settling tank and the feeding pipe between the material channeling pipe and the No.2 separating and settling tank; according to the system, by arranging the material channeling pipe, the material channeling control valve and the feeding control valve, enough treatment time and space are reserved for the separation settling tank with the poor tank condition, the technical problem that the tank condition of the separation settling tank is poor is solved, stable production and operation of the separation settling tank are guaranteed, and then stable production and operation of the settling system are guaranteed.
