The utility model relates to a fully closed dust cover for blast furnace charging vibrating screen, which belongs to the technical field of blast furnace charging equipment. The technical scheme consists of a cover body (1), a glial skin (2), a rubber strip (3), a movable connecting rod (5) and a vibrating screen (7), a cover (1) on the vibrating screen (7), and a rubber strip (3) between the cover (1) and the vibrating screen (7). The cover (1) has a hole on the top and the bottom, and the colloidal skin (2) is covered by the cover (1). On the hole, the colloid skin (2) is fixed on the cover (1) through the movable connecting rod (5). When examining the material surface, the movable connecting rod side of the glial skin on the lower part of the lower part of the cover is unloaded and the gelatinous skin can be uncovered to watch the material and the material condition. When the vibrating screen and the cutting mouth are overhauled, all the movable connecting rod of the fixed gelatin skin is unloaded and the gelatinous skin can be overhauled. The beneficial effect of the utility model is that the raw material condition and the maintenance screen surface are conveniently checked, and the sealing performance is good and the service life is long.

一种高炉上料振筛用全封闭式除尘罩
本技术涉及一种高炉上料振筛用全封闭式除尘罩,属于冶金行业高炉上料设备
技术介绍
高炉冶炼时,矿石和焦炭需要通过振筛筛去粉料后才能使用。振筛一般是斜面安装,振筛底面设有间距固定的筛棍,筛棍面积约3到4平方。振筛上接料仓下料口,下部连接分散称量斗,振筛安装有偏心轮振动电机。工作时先启动振筛,料仓下料口闸门打开,原燃料流到振筛筛面,粉料经过筛眼筛除,大颗粒的原燃料经振筛底部进入分散称量斗。在此过程中,由于振筛强烈振动,会在筛面上形成大量扬尘,尤其是焦炭和块矿由于携带大量粉尘,极易污染环境。由于场地限制,传统的做法是在分散称量斗和筛底连接处的上方设除尘抽口,来抽除振料时形成的扬尘,由于振筛筛面大,漏风率高,抽风效果差,除尘能力有限。另外,也有给筛面加装简单的钢板焊接的盖板的,但筛面时常需要清理检修和观察原料情况,盖板移动不便,不利于检修下料口和原料观察,另外,由于振筛振动强烈,盖板容易脱落,使用寿命短。
