Abstract

The present invention relates to a stirring paddle for a mechanical stirring apparatus. The stirring paddle comprises a stirring paddle support base and stirring paddle blades, wherein the stirring paddle support base comprises a stirring main shaft, a support plate fixedly arranged on the stirring main shaft and a fixation frame connected with the support plate. The stirring paddle has characteristics of simple and unique structure, low cost and short production cycle, provides creative improvement for the stirring paddle for the existing domestic mechanical stirring equipment, is suitable for hydrometallurgy, chemical industry, phosphate fertilizer, and other industries, and provides significant economic benefits and social benefits. In addition, based on a large amount of designs, manufactures and installations of stirring equipment and various steel components, the stirring paddle is completed through careful design calculation and assurance of the strength required by stirring.

Description

technical field [0001] The invention relates to a stirring device, in particular to a stirring paddle for mechanical stirring equipment. Background technique [0002] At present, most domestic alumina factories use alumina seed decomposition tanks with diameters of φ14m, φ12m, φ10.5m, and φ7m. The height of the tank ranges from 18m to 36.5m, and the maximum volume reaches 5400m3. The φ14×36.5m seed separation tank is the largest in China. Solid-liquid suspension stirring tank. In 1990, the intermig paddle introduced in Guangxi was used in φ14m sub-troughs, and the stirring effect was not ideal. Therefore, my country's design institute improved the intermig paddle, and the effect was good, and it began to be widely used in China. In recent years, my country's alumina industry has developed rapidly, and nearly a thousand φ14m sub-troughs have been newly built or rebuilt. [0003] Since the diameter of the four-layer blades on the upper part of the 14m kind of tank currently...
