CRUSHED STONE SHAPING DEVICE AND SHAPING METHOD THEREFOR
PROBLEM TO BE SOLVED: To perform breaking and shaping of a crushed stone which is different from a conventional one.SOLUTION: Grinding of a crushed stone a is performed by a centrifugal pump 20. The centrifugal pump has a vane wheel 22 in a casing 21, sucks crushed stone mixed water b from a center from the casing, gives a centrifugal force to said crushed stone mixed water by the vane wheel, and discharges crushed stone mixed water c from a feed-out pipe 15, which is continuous with an outer periphery of the casing, by the centrifugal force. In this pump action, the crushed stone a receives an impact force by a vane of the vane wheel and is ground, and crushed stones are ground by mutual collision. That is, grinding and shaping of crushed stone are performed by this centrifugal pump. In this respect, a spiral baffle plate 12 is interposed in a feed-in pipe 14 of the centrifugal pump thereby causing crushed stone mixed water, which enters into the centrifugal pump, to generate swirling action, and thus, stone crushing and shaping action can be promoted. Further, a resistance plate, which changes an inner diameter of the feed-out pipe of the centrifugal pump, is interposed in the feed-out pipe thereby generating a turbulent flow, and thus, stone crushing and shaping action can be promoted.SELECTED DRAWING: Figure 1
【課題】従来と異なる砕石の破砕・整形を行う。【解決手段】渦巻きポンプ２０によって砕石ａの磨砕を行う。渦巻きポンプは、ケーシング２１内に羽根車２２を有し、そのケーシングの中央から砕石混合水ｂを吸い込み、羽根車によりその砕石混合水に遠心力を付与し、その遠心力によりケーシングの外周に連続する送り出し管１５から砕石混合水ｃを吐出する。このポンプ作用において、砕石ａは羽根車の羽根によって衝撃力を受けて磨砕するとともに、砕石同士が衝突し合って磨砕する。すなわち、この渦巻きポンプによって砕石の磨砕と整形が行われる。このとき、渦巻きポンプの送り込み管１４に螺旋状の邪魔板１２を介在し、渦巻きポンプに入る砕石混合の水に渦巻き作用を生じさせて砕石及び整形作用が促進する。また、渦巻きポンプの送り出し管にもその内径を変化させる抵抗板を介在して乱流を生じさせて前記破砕及び整形作用を促進させる。【選択図】図１
