【技术实现步骤摘要】
一种新型大角度滚轴筛
本技术涉及选矿领域,具体的是一种新型大角度滚轴筛。
技术介绍
滚轴筛的筛面由很多根平行排列的、其上交错地装有筛盘的辊轴组成,滚轴通过链轮或齿轮传动而旋转,其转动方向与物料流动方向相同。现有的筛盘固定在滚轴的方式大多为焊接和螺纹连接,焊接导致后期的维修清理不便,螺纹连接时当出现卡煤现象时,在煤矿的轴向挤压力作用下,固定的螺栓较易折断,给筛分工作造成不便;同时,现有常规使用的滚轴筛与水平面形成的夹角固定,大多夹角角度为10°左右,在处理大粒度筛分时,常会出现积煤、卡煤的现象,需要停机进行清理后才能正常使用。当夹角增加时,物料经过筛面时,受重力作用影响,通过筛面速度变快,筛分效率更高,经计算及生产现场试验,当夹角角度为17°时,筛分效率最好。
技术实现思路
本技术的目的在于提供一种新型大角度滚轴筛,本技术设有驱动件,通过驱动气缸,滚轴箱整体可绕着转轴转动,能够根据现象施工的需要调节滚轴筛与水平面形成的夹角,当增加夹角时,筛分效率更高,避免了物料卡入筛轮造成卡煤、积煤的现 ...
