Technical field
The utility model relates to centrifugation apparatus technical field, the made up blade wheel structure that particularly a kind of design for change is simple, lighter weight, air quantity are higher.
Background technique
Impeller, as the critical component of dynamic power machine, is widely used in every field, and the profile of impeller blade is very complicated, very large to performance impact, the development and design cycle of blade, front and back dish and axle sleeve is long, and manufacturing effort is large, and its processing technique is regarded as the important ring in manufacturing industry always.Conventional machining process takes parts processing scheme, and namely blade and wheel hub adopt different blanks respectively, are welded on wheel hub by blade after shaping respectively.The program not only wastes time and energy, and is difficult to the property indices ensureing impeller.
Therefore, be necessary to provide a kind of new blade wheel structure to solve the problems referred to above.
Model utility content
Main purpose of the present utility model is to provide the made up blade wheel structure that a kind of design for change is simple, lighter weight, air quantity are higher.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of made up impeller, comprise shroud, hub disk and be located at the some blades between described shroud and hub disk, described blade is the wing-shaped structure with inner chamber, two outlets of described inner chamber are respectively equipped with front rivet fixed block and rear rivet fixed block, described shroud is fixed by rivet and front rivet fixed block, and described hub disk is fixed by rivet and rear rivet fixed block.
Concrete, described front rivet fixed block is at least two.
Further, the both sides being located at described inner chamber of described front rivet fixed block and described rear rivet fixed block symmetry.
Further, in described inner chamber one-body molded have some to fixed groove, before described in often pair of described fixed groove collecting one described in rivet fixed block and after rivet fixed block.
Further, described front rivet fixed block and rear rivet fixed block are has externally threaded column structure, and described fixed groove inside is provided with for coordinating described externally threaded internal thread.
Further, stiffening rib is provided with in described inner chamber.
Concrete, described blade is cylindricality contour everywhere, the shroud plane that described shroud exports before having closed described inner chamber, the hub disk plane that described hub disk exports after having closed described inner chamber.
Adopt technique scheme, the beneficial effect of technical solutions of the utility model is: the blade that the utility model adopts hollow machine wing, alleviate Impeller Mass, improve impeller air quantity, rivet immovable point is located at blade inner chamber simultaneously, and avoiding air channel has protrusion and affect air quantity, and structure replaceable, impeller air quantity can change with the change of blade height, without design iterations.

Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
As shown in Figure 1 to Figure 3, a kind of made up impeller of the present utility model, the some blades 3 comprising shroud 1, hub disk 2 and be located between shroud 1 and hub disk 2, blade 3 is for having the wing-shaped structure of inner chamber 3a, inner chamber 3a two outlets are respectively equipped with front rivet fixed block 4a and rear rivet fixed block 4b, shroud 1 is fixed with front rivet fixed block 4a by rivet 5, and hub disk 2 is fixed with rear rivet fixed block 4b by rivet 5.The air quantity of impeller is subject to the impact of blade 3 form, and under same speed conditions, the blade 3 of airfoil can provide larger air quantity than the blade of sheet; Inner chamber 3a alleviates the material consumption of blade, makes Impeller Mass lighter; Shroud 1, fixing between hub disk 2 and blade 3 are located by rivet fixed block 4a, the 4b being positioned at inner chamber 3a, and rivet 5 can not protrude from the air channel between blade 3, therefore can not cause resistance and affect air quantity; According to different air quantity requirements, as long as the blade 3 that impeller replaces different heights can realize, shroud and hub disk need not redesign.
As shown in Figure 3 and Figure 4, front rivet fixed block 4a and rear rivet fixed block 4b is two, the both sides being located at inner chamber 3a of front rivet fixed block 4a and rear rivet fixed block 4b symmetry, one-body molded in inner chamber 3a have two pairs of fixed grooves 31, rivet fixed block 4b after rivet fixed block 4a and before often pair of fixed groove 31 accommodates.Two front rivet fixed block 4a provide blade 3 and shroud 1 two fixed positions, after two, rivet fixed block 4b provides blade 3 and hub disk 2 two fixed positions, in such wheel rotation, even if blade 3 is subject to influenced by wind pressure also can not change the relative position in impeller, guarantee structural stability.
As shown in Figure 3, front rivet fixed block 4a and rear rivet fixed block 4b is the column structure with outside thread 41, and fixed groove 31 inside is provided with the internal thread 311 for coordinating outside thread 41.Front like this rivet fixed block 4a and rear rivet fixed block 4b is all assembled into inside blade 3 by thread fiting mode, this mode convenient fixing, and blade 3 is dismantled and replaced simply.
As shown in Figure 3 and Figure 4, stiffening rib 32 is provided with in inner chamber 3a.Stiffening rib 32 can strengthen the structural strength in the horizontal thickness of blade 3, prevents blade 3 to be out of shape by the pressure of ecto-entad; When for front rivet fixed block 4a and after under rivet fixed block 4b thread set is loaded in blade 3 occasion, can prevent inside fixed groove 31 stressed, outwards make a concession and cause the situation of screw thread solid failure.
As shown in figures 1 and 3, blade 3 is cylindricality contour everywhere, the shroud plane 1a that shroud 1 exports before having closed inner chamber 3a, the hub disk plane 2a that hub disk 2 exports after having closed inner chamber 3a.Such shroud plane 1a is parallel with hub disk plane 2a, intersection can be avoided to have space and cause leaking out when split with the blade 3 of cylindricality.
Above-described is only mode of executions more of the present utility model.For the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
