PROBLEM TO BE SOLVED: To effectively collect even bulky dust by a push-pull dust collection method and to precisely in a short time finish design which has been done by intuition. SOLUTION: Dust suction ports for fine dust and for bulky dust are formed, and dust-containing air is lead to a dust box and a dust collector to recover the fine dust and the bulky dust separately. A dust collector designed precisely is materialized in a short time by a finite element method by using a computer. |
