  • the invention relates to a raw material conveying elbow, in particular to an anti-wear material conveying elbow.
  • the raw materials used in the manufacture of anodes for electrolytic aluminum are mainly hard, multi-angled, rough and irregular calcined petroleum coke. Affected by factors such as long carbon process flow, large equipment variation, large particle size, and complex formula, the transportation of calcined coke requires a large number of pipes, especially curved pipes of various shapes and sizes. At present, the anode material transportation of raw materials is mostly carried out by ordinary steel pipes, so that in the corners of the pipeline, the direct contact, friction and collision of the calcined coke and the steel pipe easily lead to wear at the bend of the pipeline, which leads to leakage of raw materials.

Abstract

L'invention concerne un élément incurvé anti-usure destiné à transporter une matière. Cet élément comprend un conduit d'alimentation 1, un corps de conduit 2 et un conduit d'évacuation 3, qui forment une garniture d'étanchéité monobloc. L'angle formé entre le conduit d'alimentation et le conduit d'évacuation est compris entre 120 et 150 degrés. Le corps de conduit est composé d'une plaque circonférencielle verticale et d'une plaque horizontale perpendiculaires entre elles. La plaque horizontale est située sur la trajectoire d'alimentation et reliée au conduit d'évacuation. Grâce à la plaque horizontale et à la plaque verticale, la matière peut s'accumuler et former une pente d'impact, ce qui arrête la matière par blocage au niveau de la paroi de conduit, aussi loin que possible. Ainsi, l'invention permet de réduire l'abrasion entre la matière et la paroi de conduit; et d'augmenter la durée de vie de l'élément incurvé servant à transporter une matière selon l'invention.
