矿浆分配管的数量为双数，均匀设置在圆筒外侧；撞击管和错流管间隔设置，撞击管为射流器结构形式；相邻错流管切向接入圆筒的方向相反，所述撞击管和错流管均水平布置，撞击管沿径向接入圆筒，即与圆筒外壁的角度为90度，错流管沿切线方向接入圆筒，即与圆筒外壁的角度为0度，撞击管和错流 管平面的夹角为0度，撞击管和错流管之间的距离为圆筒内径的0.5～1.5倍。
一种流体协同强制混合调质方法，其步骤如下：
a.首先将矿浆和药剂由进料管的进口A给入圆筒底部，打开圆筒底部预循环矿浆出口管路上的电动阀；
b.矿浆和药剂经圆筒底部的预循环矿浆出口在循环泵的抽吸作用下进入矿浆循环系统的矿浆分配环；
c.在压力的作用下，矿浆和药剂进入多根矿浆分配管并分别通过撞击管和错流管喷入圆筒内部；
d.通过撞击管和错流管喷入圆筒内部的矿浆和药剂在筒内形成高速撞击流和强制剪切错流，实现筒体内矿浆中颗粒与药剂的充分混合和分散，有效强化药剂在颗粒表面的吸附；
e.当给料矿浆充满立式筒体后，关闭预循环矿浆出口管路上的电动阀，保持矿浆进料管13进料，筒体内的部分矿浆由圆锥顶部的矿浆出料管的出口B排出，进入后续浮选作业；部分矿浆由梯形锥台顶部的循环矿浆出料管在循环泵的抽吸作用下进入矿浆循环系统，实现矿浆的多次循环混合调质。

  6. 根据权利要求4所述流体协同强制混合调质方法，其特征在于：圆筒(10)径向对称设置的撞击管(2)喷射出的矿浆发生正面撞击产生高速撞击流，圆筒(10)切向设置的上下层切入方向相反的错流管(3)喷射出的顺时针方向矿浆和逆时针方向矿浆之间产生剪切错流。
  7. 根据权利要求4所述流体协同强制混合调质方法，其特征在于：所述药剂为浮选药剂，如捕收药，包括柴油、煤油，起泡剂，包括松醇油。
