Red mud pulping device and control system

Abstract

The invention is applicable to the technical field of non-ferrous metals, and provides a red mud pulping device and a control system. The red mud pulping device comprises a feeder, a metering conveyorand a pulpizer, wherein the feeder is used for containing a red mud material and is provided with a discharge device; the metering conveyor is arranged below the feeder and is used for conveying andmetering the material; the pulpizer is communicated with a water source, controls the flow through a metering piece and is used for pulpifying the red mud material; the bottom of the pulpizer is communicated with a pulp discharge pipe; the feeder, the metering conveyor, the pulpizer and the metering piece are electrically connected with a controller; and feeding of the feeder, conveying of the metering conveyor, pulpifying of the pulpizer and metering of water are controlled through the controller. Control is carried out through the controller, so that control on the pulping concentration is achieved; automatic control on the ratio is completed; the control is accurate; and the production efficiency is high. The red mud pulping device has the advantages of being simple in structure and convenient to operate; the workload is reduced; the work efficiency is improved; and automatic control is achieved.

Description

technical field [0001] The invention belongs to the technical field of nonferrous metals, and in particular relates to red mud pulping equipment and a control system. Background technique [0002] Red mud is the polluting waste slag discharged when the aluminum industry extracts alumina. Generally, for every ton of alumina produced, 1.0~2.0 tons of red mud is incidentally produced. As the world's fourth largest producer of alumina, China discharges millions of tons of red mud every year. Also known as red mud, it is an industrial solid waste discharged after refining alumina from bauxite. Generally, it contains a large amount of iron oxide, and its appearance is similar to red soil, hence the name. But some are brown or even off-white because they contain less iron oxide. For those with high aluminum content in bauxite, the Bayer method is used to smelt aluminum, and the red mud produced is called Bayer red mud; for those with low aluminum content in bauxite, the sinterin...
