Abstract
The utility model relates to a rotor with a replaceable classifying blade, in particular to a cage type rotor with the replaceable classifying blade used in a large-scale roller mill used powder separator. The utility model includes a disc and the classifying blade, wherein the dismountable classifying blade is fixed on the disc. The disc is divided into an upper disc, a middle disc and a lower disc, which are welded into a whole through a connecting steel tube in equidistance and are provided with grooves to fix the classifying blade. One side of the classifying blade close to the center of rotation is located by a baffle, the baffle and the blade are fixed on the upper, middle and lower discs by bolts, and the other side of the blade is fixed by the grooves of the upper, middle and lower discs. The two ends of the classifying blade present ladder forms. The rotor with the replaceable classifying blade has the advantage that: when the classifying blade is badly worn, the classifying blade can be taken away and replaced after unscrewing the bolts and taking away the baffle. The design with the simple and convenient disassembly saves the material and lowers the cost.
Description
Technical field
The utility model relates to a kind of rotor of replaceable graded blade, is applied in the replaceable graded blade formula cage-type rotor in the large-scale Vertical Mill usefulness powder concentrator specifically.
Background technology
As everyone knows, Vertical Mill is the more serious part that weares and teares with the graded blade on the powder concentrator rotor, and both at home and abroad the graded blade overwhelming majority of present used powder concentrator is welded on the disk, the situation that can't change after so just having caused blade wear to scrap.If wanting to change blade must together change by whole rotor, so just caused the waste of material, increased cost.
Summary of the invention
At the deficiency of existing powder concentrator rotor technology, the utility model provide a kind of rational in infrastructure, use cost is low and the replaceable graded blade formula cage-type rotor of easy removal.
The utility model is achieved through the following technical solutions:
The utility model comprises disk and graded blade, and wherein, described graded blade is detachable to be fixed on the disk.
Described disk is divided into the upper, middle and lower disk, and steel pipe is equally spaced to be welded as a whole the three by connecting, and the upper, middle and lower disk is provided with the fixedly groove of graded blade.
Described graded blade is located with baffle plate near pivot one side, by bolt with baffle plate and vanes fixed on the disk of upper, middle and lower, the opposite side of blade is fixed by the groove on the disk of upper, middle and lower.
Described graded blade two ends are stepped.
The utility model adopts the vanes fixed of special shape on disk, and wherein disk is welded by thin steel plate and thicker two kinds of steel plates of steel plate, as support, is used for fixing graded blade than fluting on the sheet metal than steel plate.Different is upper and lower disk is welded than steel plate than sheet metal and one by one, and middle disk is welded than steel plate than sheet metal and one by two.The graded blade outside is fixed by groove, and the inboard blade of close pivot one side is just located with baffle plate, and then with screw bolt and nut baffle plate is fixed on than on the steel plate.
The beneficial effects of the utility model: bolt can be turned on during as if the graded blade serious wear, take baffle plate away, take out graded blade then it is changed, this designs easy removal, has saved material, has reduced cost.

The specific embodiment
Embodiment: structure is shown in Fig. 1,7, and the utility model places lower disc 9 and axle 1 lower end on the same horizontal plane, lower disc 9 is welded on the axle 1 pull bar 2 is wanted on uniform and the lower disc that staggers during welding through hole and screwed hole with pull bar 2.Collet 8 is put into from top to bottom, placed on the lower disc 9 and middle axle 1, lower disc 9 welds together.To go up disk 4 with connecting steel pipe 5 by the hole on the disk, middle disk 7, lower disc 9 equidistantly are welded on one, and then respectively middle disk 7, last disk 4 are welded on collet 8 and the axle 1 with uniform pull bar 2.Shown in Fig. 2,3,4, graded blade 6 is inserted piecewise in the groove of disk, again with the inboard of baffle plate 11 retainings at blade 6, with bolt I10, bolt II12 and nut 13 screwed hole or the through hole of baffle plate 11 by disk is fixed on the disk, at last vanelets 3 is welded in uniform way disk than on the steel plate.As Fig. 5, shown in Figure 7, graded blade 6 near pivot one sides with baffle plates 11 location, by bolt with baffle plate and vanes fixed on the disk of upper, middle and lower, the opposite side of blade is fixed by the groove on the disk of upper, middle and lower.As shown in Figure 6, graded blade 6 two ends are stepped.
If bolt 10 and 12 can be turned on during graded blade 6 serious wear, take baffle plate 11 away, take out graded blade 6 then with its replacing.
