新型电石炉下料柱
:本技术涉及一种电石炉下料柱,特别涉及一种新型电石炉下料柱。
技术介绍
:电石炉是电石生产的主要设备,电石生产时,焦炭和白灰等原料通过皮带输送至环形加料机,然后根据需要由环形加料机分别加至12个料仓,料仓下方有下料管,下料管下方在靠近电极位置有下料柱,下料柱是围绕电极分布的,原料通过下料柱均匀的分布在电极四周,并依靠三相电极的电弧热进行熔炼。正常生产时,原料必须堆积在电极四周才能实现闭弧操作,若弧光外露,则电极的弧光热会造成料面温度升高,就会烧损炉盖、密封套等通水设备;另外,现有的下料柱多为铸铁制造,在高温条件下容易烧损,下料柱烧损后料面就会抬高,料面与炉盖、密封套等通水设备距离变近,导致通水设备烧损;一旦高温原料与通水设备接触,就会发生联电刺火打烂通水设备的问题,造成漏水事故。
技术实现思路
:本技术的目的在于提供一种确保下料均匀、避免通水设备烧损、节约生产成本的新型电石炉下料柱。本技术由如下技术方案实施:新型电石炉下料柱,其包括支撑板和下料管,所述下料管固定设置在所述支撑板上方,所述下料管底部端面与所述下料管横截面之间的夹角α为32°-47°。进一步的,所述下料管的管壁内设有循环水夹层,在所述支撑板上固定设有进水管和出水管,所述进水管的出水端和所述出水管的进水端分别穿过所述支撑板并置于所述循环水夹层内。进一步的,在所述循环水夹层内部侧壁之间上下交错固定设有若干个挡水片。本技术的优点:1、本技术下料管底部为斜口,可以保证原料均匀堆积在圆形电极四周,避免工作状态下电石炉电极弧光外露,造成料面温度升高,烧损炉盖、密封套等通水设备的问题;2、下料管内 ...
