Abstract

一种热镀锌长杆内吹同步冷却装置包括有齿轮箱、电机、内吹小车、道轨、内吹杆、夹紧装置、托辊、蒸汽进口、空压气进口、蒸汽内管、压缩空气外套管、冷却孔和吹头座。压缩空气外套管(11)套在蒸汽内管(10)外部，形成内部蒸汽空腔和外部压缩空气空腔两个完全隔离的空腔。其优点是避免镀锌钢管在镀锌后出现起花、发乌现象，从而提高镀锌质量。

Description

热镀锌长杆内吹同步冷却装置
一、技术领域：
本实用新型涉及一种钢管热镀锌长杆内吹同步冷却装置。 
二、背景技术：
目前，钢管热镀锌企业采用的生产工艺、设备装备水平相对比较独特。在镀管从锌锅中导出后，由长杆内吹管通过蒸汽把残存于镀管内的液态锌吹出，从而使锌得到充分回收利用，降低生产成本。 
三、实用新型内容：
为了克服传统钢管热镀锌长杆内吹装置容易造成热镀锌管表面出现起花、发乌，从而导致镀锌质量下降的不良现象，本实用新型在原热镀锌长杆内吹管的基础上进行了改造，变原来单管结构为内外套管的双层结构。 
本实用新型解决其技术问题所采用的技术方案是：改原来热镀锌长杆内吹管单管结构为双层套管结构。本热镀锌长杆内吹同步冷却装置包括蒸汽进口、空压气进口、压缩空气外套管、蒸汽内管、冷却孔和吹头座组成。其特征是压缩空气外套管(11)套在蒸汽内管(10)的外部形成内部蒸汽空腔和外部压缩空气空腔两个完全隔离的空腔。在热镀锌长杆内吹管正常前进过程中，蒸汽内管吹出高温、高压蒸汽；在热镀锌长杆内吹管后退时，蒸汽内管停止吹高温、高压蒸汽，压缩空气外套管吹出压缩空气，从而使热镀管快速冷却。整个吹锌动作与冷却动作由电控装置自动控制，达到在一次吹锌动作过程中同时完成内吹蒸汽和冷却降温两种功能。 
本实用新型的有益效果是：使热镀锌钢管在完成吹锌动作同时完成热镀锌钢管冷却，避免镀锌钢管在镀锌后出现起花、发乌现象，提高了镀锌质量。 
四、附图说明：(见附图1、图2) 
(图1)为热镀锌长杆内吹同步冷却装置，包括有齿轮箱(1)、电机(2)、内吹小车(3)、道轨(4)、内吹杆(5)、夹紧装置(6)、托辊(7) 
(图2)是热镀锌长杆内吹同步冷却装置的吹杆示意图：蒸汽进口(8)、空压气进口(9)、蒸汽内管(10)、压缩空气外套管(11)、冷却孔(12)和吹头座(13) 
五、具体实施方式：
如图1所示，本热镀锌长杆内吹同步冷却装置，包括有齿轮箱(1)、电机(2)、内吹小车(3)、道轨(4)、内吹杆(5)、夹紧装置(6)、托辊(7)、蒸汽进口(8)、空压气进口(9)、蒸汽内管(10)、压缩空气外套管(11)、冷却孔(12)和吹头座(13)。其特征是在热镀锌长杆内吹管正常前进过程中，蒸汽内管(10)吹出高温、高压蒸汽；在热镀锌长杆内吹管后退时，蒸汽内管(10)停止吹高温高压蒸汽，压缩空气外套管(11)吹出压缩空气，使热镀管快速冷却，从而避免镀锌管起花、发乌。整个动作由电控装置自动控制，达到在一次吹锌动作中同时完成内吹功能和冷却功能。
