Abstract

冶金用烧结机抽风烧结系统用的一种耐磨弯管，其特征是，在管体1的转折处外壁3上，焊接一个用10mm厚钢板组成的盖罩2，盖罩空腔内有耐温、耐磨的充填材料4。有充填材料的阻碍，减缓了带粉尘颗粒的高温、高速气流的冲刷破坏效果。当转折处快磨穿时，整个管道系统也需要更换了，无需为转折处的局部磨损而中途停产检修。

Description

耐磨弯管
技术领域
本实用新型涉及冶金用烧结机抽风烧结系统的一种耐磨弯管。
背景技术
烧结机抽风烧结系统，风温高达400℃，风速16m/s，气流带着粉尘和有尖角的颗粒在弯管的转折处通过时，其冲刷力量对弯管外壁有很大的磨损破坏作用。为了对弯管转折处进行局部保护，曾有过附加盖板装置的技术方案问世，但使用寿命不长，且盖板漏风及装卸麻烦。
发明内容
本实用新型的任务，是要提供一种易安装，使用寿命长的耐磨弯管。
实用新型是这样实现的：在弯管转折处的管体外壁，焊接一个由钢板组成的盖罩，盖罩与外壁内腔装有填充材料。
本实用新型的弯管转折处，形成了一个加厚的耐温、耐磨保护层，使它的使用寿命延长到与其它管壁同步，不需为转折处的磨损而中途检修。保护层设置简便。
附图说明
下面结合附图介绍本实用新型。
图1为实用新型主视图；
图2为图1中A-A剖视图。
图中1、管体，2、盖罩，3、转折处外壁，4、充填材料。
实施方式
参照附图，在管体1的转折处外壁3上，焊接一个用10mm厚钢板组成的盖罩2，盖罩空腔内有耐温、耐磨的充填材料4。有充填材料的阻碍，减缓了带粉尘颗粒的高温、高速气流的冲刷破坏效果。当转折处快磨穿时，整个管道系统也需要更换了，无需为转折处的局部磨损而中途停产检修。
