The center of existing granulating wheel is provided with a tubular shaft; the two ends of granulating wheel are respectively provided with an annular wallboard; between two annular wallboards, be provided with centered by tubular shaft; be some support disc that divergent shape distributes; at the middle part of tubular shaft, be provided with a minute slag pan, within described minute, slag pan comprises two sputter conical surfaces.Between two annular wallboards, be also provided with and the blade that supports disc quantity and equate, blade is positioned at the outside of minute slag pan.
Blade is generally wolf's fang club shaped structure, less with the contact area of slag, lower to the breaking capacity of slag, and when especially the viscosity of slag is larger, treatment effect is very undesirable; In addition, the installation of blade is insecure, high capacity produce and severe Working environment under, easily occur that parts get loose.
Utility model content
The purpose of this utility model is to improve installation stability and the reliability of granulating wheel Leaf, and increases the contact area of blade and slag, improves the breaking capacity of granulating wheel.
For reaching above-mentioned purpose, a kind of blast furnace metallurgical slag granulation wheel that the utility model provides, the center of this granulating wheel is provided with a tubular shaft (1), the two ends of granulating wheel are respectively provided with an annular wallboard (2), between two annular wallboards (2), be provided with centered by described tubular shaft (1), be some support disc (3) that divergent shape distributes, at the middle part of tubular shaft (1), be provided with a minute slag pan (4), described minute slag pan (4) comprise two sputter conical surfaces (4a), between two described annular wallboards (2), be also provided with and the blade (5) that supports disc (3) quantity and equate, blade (5) is positioned at the outside of a minute slag pan (4), key is: described blade (5) is dismountable straight-tooth, and by being fixed on the rest pad (6) supporting on disc (3) and the pressed seat (7) being fixed on annular wallboard (2), blade (5) is clipped in the middle firmly, again by bolt (9) by rest pad (6), blade (5) and pressed seat (7) are locked together.
Described rest pad (6) is straight plate, in the below of rest pad (6), is vertically welded with triangle gusset (8); Described pressed seat (7) is whole L-shaped, orthogonal pressure strip (7a) and welded plate (7b), consists of.By optimizing the structure of rest pad, pressed seat, simplify processing, reduce manufacturing cost; Meanwhile, set up triangle gusset, improve the bearing value of rest pad.
Further, described support disc (3), blade (5) are respectively eight, each blade (5) correspondence is provided with two pairs of rest pads (6) and pressed seat (7), and every pair of rest pad (6) and pressed seat (7) are locked together by two bolts (9) with blade (5).Support disc, blade that magnitude setting is suitable, and corresponding mounting fixing parts, further guaranteed the reliability service of granulating wheel and the installation reliability of blade.
The beneficial effects of the utility model are:
(1) due to blade serious wear in use, need to often change, be therefore designed to demountable structure, be convenient to change at any time;
(2) blade is arranged to straight-tooth structure, can be increased the contact area of blade and slag, improve the breaking capacity to slag, be particularly suitable for the slag that viscosity is larger and use, treatment effect is very good;
(3) by rest pad and pressed seat, jointly clamp blade, and joint bolt locking, guaranteed stability and the reliability of blades installation, avoid high capacity produce and severe Working environment under, there is the phenomenon that parts get loose.
