第一是原煤储煤场下的14台手动双扇形闸门,倾角45°,偏小,易堵煤,后将一扇固定改为单扇形,操作时需将活动的一扇对固定的一扇进行猛烈撞击,否则煤难以流出,劳动强度很大,同时给煤又不均匀,造成皮带跑偏。 第二是原煤没有除铁环节,由于原煤中的铁器,经常造成机械事故,影响生产,尤其是203破碎机和303跳汰机的排料轮事故最多。 第三是当煤易选时,301胶带输送机输送能力显得低,供不上主洗机入洗。 为了减轻工人笨重的体力劳动,改善工作条件,减少机械事故,提高原煤入洗能力,根据洗煤厂的具体情况,确定对以上三个环节进行改造。
The first is 14 manual double-fan gate under the coal storage yard, the inclination angle of 45 °, small, easy to block coal, after a fixed to a single fan, the operation needs to be a fixed pair of activities A violent impact, or difficult to flow out of coal, labor-intensive, at the same time to the coal and uneven, resulting in belt deviation. The second is that the raw coal does not have the iron removal link. Due to the ironwork in the raw coal, mechanical accidents are often caused and the production is affected. In particular, the discharge of 203 crushers and 303 jiggers has the most accidents. The third is when the coal is easy to choose, 301 conveyor belt conveyor capacity appears to be low, not for washing machine wash. In order to reduce heavy workers manual labor, improve working conditions, reduce mechanical accidents, improve raw coal washing capacity, according to the specific circumstances of coal preparation plant, to determine the above three aspects of transformation.
