Abstract

The utility model belongs to the technical field of the centrifugal fan technique and specifically relates to a novel open centrifugal fan impeller, is equipped with impeller hub, impeller blade, couples on impeller hub through the welding mode at the radial impeller blade impeller blade who extends in impeller hub's a plurality of edges of radial evenly distributed, its characterized in that impeller blade uses impeller hub radially for the axle center distortion forms by square adj. Tabular face, the arcwall face that makes impeller blade form the distortion is favorable to carrying the gas that contains a large amount of suspended solids, reaches and takes out the swift effect of dirt, has avoided impeller blade surface deposition not enough easily, simultaneously, owing to having saved shroud and hub disk, has practiced thrift the material, has that the structure is succinct, the appearance is compact, advantages such as simple manufacture, wearability are good, intensity height.

Description

Novel open type centrifugal blower fan blade wheel
Technical field
The utility model relates to centrifugal blower technical field, specifically a kind of novel open type centrifugal blower fan blade wheel.
Background technique
The Main Function of centrifugal blower fan blade wheel is: coupled drive shaft, the energy of live axle is transferred to the mechanical energy of impeller, and airflow direction goes out for axially flowing into radial flow.General centrifugal blower fan blade wheel contains wheel hub, blade, shroud and hub disk, and obtains finished product by the method for general connecting mode (welding, riveted joint).But this centrifugal impeller can need to hold different moulds because of the difference of impeller size size and the difference of model, and connection comparatively bothers, and therefore, the shortcoming of this centrifugal blower fan blade wheel has:
1, component are more, making is comparatively complicated.
Dust stratification is easy to when 2, taking out dirt.
Summary of the invention
The purpose of this utility model solves above-mentioned the deficiencies in the prior art, provides simple for structure, compact appearance, making is simple, wear resistance good, the novel open type centrifugal blower fan blade wheel of intensity advantages of higher.
The utility model solves the technological scheme that its technical problem adopts:
A kind of novel open type centrifugal blower fan blade wheel, be provided with impeller hub, impeller blade, being uniformly distributed multiple impeller blade impeller blade radially extended in the radial direction of impeller hub is connected on impeller hub by welding manner, it is characterized in that described impeller blade is formed for axle center distortion so that impeller hub is radial by square tabular face, impeller blade is made to form the arc shaped surface of distortion, be conducive to carrying the gas containing a large amount of suspended matter, reach and take out dirt and act on efficiently, avoid the deficiency of the easy dust stratification in impeller blade surface, simultaneously, owing to eliminating shroud and hub disk, save material.
The ratio of impeller hub diameter D1 described in the utility model and impeller diameter D2 is the proportionate relationship of 0.25-0.5:1, this setting, makes to be significantly improved by the speed of flow field gas, effectively improves impeller adiabatic efficiency, reduces impeller noise.
The utility model, owing to adopting said structure, has simple for structure, compact appearance, making is simple, wear resistance good, intensity advantages of higher.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of the left view of Fig. 1.
Reference character: impeller hub 1, impeller blade 2.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated:
As shown in drawings, a kind of novel open type centrifugal blower fan blade wheel, be provided with impeller hub 1 and impeller blade 2, multiple impeller blade 2 radially extended is uniformly distributed in the radial direction of impeller hub 1, impeller blade 2 is connected on impeller hub 1 by welding manner, it is characterized in that described impeller blade 2 is formed for axle center distortion so that impeller hub is radial by square tabular face, impeller blade 2 is made to form the arc shaped surface of distortion, be conducive to carrying the gas containing a large amount of suspended matter, reach and take out dirt and act on efficiently, avoid the deficiency of the easy dust stratification in impeller blade surface, simultaneously, owing to eliminating shroud and hub disk, save material.
The ratio of impeller hub 1 diameter D1 and impeller diameter D2 described in the utility model is the proportionate relationship of 0.25-0.5:1, this setting, makes to be significantly improved by the speed of flow field gas, effectively improves impeller adiabatic efficiency, reduces impeller noise.
As shown in drawings, when making, impeller blade is connected on impeller hub by welding manner, and be uniformly distributed multiple impeller blade radially extended in the radial direction of impeller hub, impeller blade 2 is fixed on impeller hub 1 by welding manner.
As shown in Figure 1, the ratio (being generally 0.25-0.5) of side plate gap b, impeller hub diameter D1 and impeller diameter D2, the distortion of impeller blade, cambered design before and after impeller blade and casing, calculated by flow field analysis, effectively improve impeller adiabatic efficiency, reduce impeller noise, impeller is open, not only not easily dust stratification, wear resistance is good, and, be also well suited for carrying the gas containing a large amount of suspended matter, impeller component are less, have the advantages such as simple for structure, compact appearance, making be simple.

Claims (2)
