Detailed Description
As shown in figures 1-3, the whole structure of the flow distribution system of the ultra-fine pulverizer mainly comprises a convex cover 1, a pulverizing disk 2, a grading wheel 3 and a flow distribution cover 4.
The flow dividing cover 4 is composed of a conical cover 6, a partition plate 8, an outer cylinder 5 and an inner cylinder 7. The shunt cover 4 is formed by sleeving three layers of ring plates together and welding, the outermost layer is an outer cylinder 5, the middle part is a conical cover 6, and the innermost layer is an inner cylinder 7; the outer cylinder 5, the conical cover 6 and the inner cylinder 7 are connected through a plurality of partition plates 8, and the partition plates 8 are vertically and annularly and uniformly distributed.
Baffle 8 includes supporting part 14, sets up vertical portion 11, arc folded plate portion 12 on the supporting part 14, and arc folded plate portion 12 is located the 11 outsides of vertical portion, forms the contained angle between the curved surface of arc folded plate portion 12 place and the plane of vertical portion 11 place.
