Abstract

本实用新型公开了一种水冷舌板。属于循环流化床锅炉U形返料器技术领域。它由左右对称的左舌板、右舌板、水冷套进口集箱、冷却管、将左舌板与右舌板相连接的销轴组成，左舌板与右舌板上对应设置有凹槽和通孔，所述冷却管位于上述凹槽中，冷却管的上端与下降管相连通，冷却管的下端与水冷套进口集箱相连通；销轴穿入通孔中。为了使左舌板与右舌板之间的连接保持高温稳定性，所述的销轴将左舌板与右舌板采用焊接方式相连接。本实用新型水冷舌板的有益效果是显而易见的，其内部设置有若干冷却管，来自下降管的水流经其内对其连续冷却，然后流向旋风分离器下部的水冷套，再进入锅筒，进入下一循环，减少了舌板的高温裂纹，延长了舌板的使用寿命。

Description

水冷舌板
技术领域
本实用新型属于循环流化床锅炉U形返料器技术领域，尤其是一种U形返料器用的舌板。
背景技术
舌板是返料器物料上升段和下降段间的隔板，它可以提高返料器的自锁气功能，防止烟火返窜。在本实用新型专利申请日前，现有技术中的循环流化床锅炉U形返料器使用的舌板采用耐热铸钢制造，无冷却装置，由于铸钢本身在高温下易产生微裂纹，微裂纹扩展后使舌板失效而损坏，影响锅炉的返料，进而影响锅炉的正常运行，严重者还会导致锅炉停止运行。
发明内容
本实用新型的目的在于克服上述现有技术的不足，提供一种用自然循环的水对其冷却使其不会因高温损坏变形，从而延长其使用寿命的水冷舌板。
本实用新型为实现上述目的所采用的技术方案是：
一种水冷舌板，由左右对称的左舌板、右舌板、水冷套进口集箱、冷却管、将左舌板与右舌板相连接的销轴组成，左舌板与右舌板上对应设置有凹槽和通孔，所述冷却管位于上述凹槽中，冷却管的上端与下降管相连通，冷却管的下端与水冷套进口集箱相连通；销轴穿入通孔中。
为了使左舌板与右舌板之间的连接保持高温稳定性，所述的销轴将左舌板与右舌板采用焊接方式相连接。
本实用新型水冷舌板的有益效果是显而易见的，其内部设置有若干冷却管，来自下降管的水流经其内对其连续冷却，然后流向旋风分离器下部的水冷套，再进入锅筒，进入下一循环，减少了舌板的高温裂纹，延长了舌板的使用寿命。
附图说明
图1是本实用新型水冷舌板的示意图。
图2是图1中的A-A剖视图。
图3是图1中的I部局部放大剖视图。
图中：1-左舌板，2-销轴，3-水冷套进口集箱，4-右舌板，5-冷却管。
具体实施方式
图1至图3为本实用新型水冷舌板的一种具体实施方式的示意图，它由左右对称的左舌板1、右舌板4、水冷套进口集箱3、冷却管5、将左舌板1与右舌板4相连接的销轴2组成，左舌板1与右舌板4采用耐热铸钢制造，在左舌板1与右舌板4相对应的面上加工出截面为半圆形的凹槽和圆形通孔，冷却管5采用无缝圆形钢管，冷却管5弯制成与上述凹槽相适应的形状并将其置于上述凹槽中，冷却管5的上端与下降管相连通，冷却管5的下端与水冷套进口集箱3相连通；销轴2穿入通孔中后，两端分别与左舌板1、右舌板4采用焊接方式相连接。
以上所列举的实施方式仅供理解本实用新型之用，并非是对本实用新型所描述的技术方案的限制，有关领域的普通技术人员，在权利要求所述技术方案的基础上，还可以作出多种变化或变形，所有等同的变化或变形都应涵盖在本实用新型的权利要求保护范围之内。

Claims (2)
