目前,传统的压力筛的筒体内壁分别连接表面平整的上导流环和下导流环,上导流环的上部与筒体内顶端之间的空间为上筛选区,而下导流环下部与筒体内底端之间的空间为下筛选区,上导流环和下导流环相互之间的间隔为尾浆区,上导流环和下导流环分别与旋翼之间有间隙,该间隙是供上下筛选区内的尾浆分别进入尾浆区的主要通道。由此,传统压力筛在实际使用当中存在以下缺点:(1)由于上导流环和下导流环分别与旋翼之间的间隙较小,使得上下筛选区内的
At present, the inner wall of the conventional pressure sieve cylinder is respectively connected with the upper flow guiding ring and the lower flow guiding ring which are flat in surface, the space between the upper part of the upper flow guiding ring and the top end in the cylinder is the upper filtering area, and the lower part of the lower flow guiding ring And the lower end of the cylinder body between the bottom of the screening area, the upper flow guide ring and the lower flow guide ring interval between the tail pulp zone, the upper flow guide ring and the lower flow guide ring, respectively, between the rotor gap, This gap is the main passage for the tailings in the upper and lower screening zones to enter the caudal zone, respectively. As a result, the conventional pressure screen has the following shortcomings in actual use: (1) Due to the small gap between the upper flow guide ring and the lower flow guide ring and the rotor respectively, the
