Abstract

An antiwear bend for conveying material includes a feed pipe (1), a pipe body (2) and a discharge pipe(3), which form one sealing piece in a whole. The angle between the feed pipe and the discharge pipe is in the range of 120 to 150 degree. The pipe body is composed of an upright circumferential plate and a horizontal plate, which are perpendicular with each other. The horizontal plate is provided on the feeding path and connected with the discharge pipe. With the aid of the horizontal plate and the upright plate, the material can accumulate and form an impacting-slope, thus block off the material with the pipe wall as far as possible. Therefore, it can relieve the abrasion between material and pipe wall and increase the service life of the bend of conveying material.

Description

抗磨损原料输送弯管  Anti-wear material conveying elbow
技术领域 Technical field
本发明涉及原料输送弯管， 特别涉及抗磨损原料输送弯管。  The invention relates to a raw material conveying elbow, in particular to an anti-wear material conveying elbow.
背景技术 Background technique
制造电解铝用阳极使用的原料主要是坚硬、 多棱角、 粗糙不规 整的煅烧石油焦。 受碳素工艺流程长、 设备多分布落差大、 颗粒等 级多、 配方复杂等因素的影响， 煅烧焦的输送需要大量的管路， 特 别是各种形状、 大小不一的弯管。 目前阳极厂对原料的输送多采用 普通钢管输送， 这样在管路的弯道处， 煅烧焦与钢管因直接接触、 摩擦和碰撞， 容易导致在管路的弯道处磨损， 进而导致原料泄露。 要解决这个问题， 要么增加钢管或钢板的厚度， 以延长更换弯管的 周期， 但这需要增加很大的建设成本， 显然是不可行的。 所以最筒 单的方法就是要在输送管路的弯道处避免煅烧焦和钢管直接接触， 避免磨损， 永不更换弯管。 而传统弯管因受原料重力作用， 煅烧焦 与钢管直接接触， 无法避免磨损， 这就需要对现有原料输送弯管进 行结构上的改进。  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. To solve this problem, either increase the thickness of the steel pipe or steel plate to extend the cycle of replacing the elbow, but this requires a large construction cost, which is obviously not feasible. Therefore, the most straightforward method is to avoid direct contact between the calcined coke and the steel pipe at the bend of the conveying pipeline, to avoid wear and never to replace the elbow. However, due to the gravity of the raw material, the calcined coke is in direct contact with the steel pipe, and wear cannot be avoided. This requires structural improvement of the existing raw material conveying elbow.

实施例一至四中所述的进料管 1 和出料管 3 的端部与外界之间 用法兰连接。  The ends of the feed pipe 1 and the discharge pipe 3 described in the first to fourth embodiments are flanged to the outside.
本发明的原料由进料管 1 的进口沿垂直挡板 4 落在水平挡板 5 或下水平挡板 7上， 堆积一段时间形成一近 45。 斜坡时， 原料停止 堆积开始沿斜坡下滑， 斜坡堆积角是死角， 原料将与底部的水平挡 板隔离。 进料管 1入口和出料管 3 出口法兰一致， 但进出料口不能 混淆， 在使用安装是不可颠倒。  The raw material of the present invention falls from the inlet of the feed pipe 1 along the vertical baffle 4 to the horizontal baffle 5 or the lower horizontal baffle 7, and is accumulated for a period of time to form a near 45. At the time of the slope, the material stops and the accumulation begins to slide down the slope. The slope accumulation angle is a dead angle and the material will be isolated from the horizontal baffle at the bottom. Feed pipe 1 inlet and discharge pipe 3 The outlet flange is the same, but the inlet and outlet are not to be confused, and the installation is not reversed.
