Abstract
The utility model discloses draught fan impellers, belong to blower technical field.This draught fan impeller solves the problems, such as that original fan impeller structure is unstable.This draught fan impeller includes pedestal and the fan blade that is distributed in around pedestal, and pedestal and fan blade are an integral structure, and the material of pedestal and fan blade is aluminium alloy, and susceptor edges are evenly distributed with multiple recesses close to the position of fan blade.This draught fan impeller compared with the prior art, forms, therefore its structure is relatively stable since pedestal and fan blade are an integral structure, and for aluminium alloy compression casting.
Description
Technical field
The utility model belongs to blower technical field, is related to a kind of draught fan impeller.
Background technique
Traditional draught fan impeller is made of multiple cold stamping hardware components, and material takes iron plate cold stamping, aluminium sheet cold
The techniques manufactures such as punching press, welding combination.If but the draught fan impeller of this structure operates for a long time under special border, is easy to happen leaf
The problems such as piece deforms.In addition, the metal object or handstone of the iron flake sucking that works under high concentrate dust environment are held when getting to blade
It is also easy to produce spark, causes dust explosion, therefore, use environment model is small.
Utility model content
The purpose of this utility model is the presence of the above problem in view of the prior art, proposes a kind of blower of stable structure
Impeller.
The purpose of this utility model can be realized by the following technical scheme:
Draught fan impeller, including pedestal and the fan blade being distributed in around pedestal, which is characterized in that the pedestal and fan blade be
The material of integral structure, the pedestal and fan blade is aluminium alloy, and the susceptor edges are uniformly divided close to the position of fan blade
It is furnished with multiple recesses.
In this draught fan impeller, since pedestal and fan blade are an integral structure, on the one hand reduce assembly process, so that raw
It is higher to produce efficiency, on the other hand, but also the structural integrity of pedestal and fan blade as a whole is preferable, improves draught fan impeller
Structural stability.In addition, the material of pedestal and fan blade is aluminium alloy, but also draught fan impeller in use, is not likely to produce
Spark, use is safer, and use scope is wide.The recess being distributed in susceptor edges, so that draught fan impeller is during the work time, warp
The air for crossing indent can generate biggish wind pressure, and help improves air quantity.
In above-mentioned draught fan impeller, there is groove perpendicular to shaft axis and in a strip shape in the shaft.
The setting of groove facilitates machine shaft insertion rear pin shaft positioning, so that draught fan impeller is using more convenient.
In above-mentioned draught fan impeller, the pedestal and fan blade are die cast as a whole.
In above-mentioned draught fan impeller, the quantity of the fan blade is seven and is evenly distributed on around pedestal.
In above-mentioned draught fan impeller, the pedestal includes shaft and the connection on the outside of shaft annular in shape
Portion, the fan blade are connected on the outside of interconnecting piece, and the fixed part of sheet is equipped between the shaft and interconnecting piece, described
Fixed part is obliquely installed, and one end of fixed part is fixed in shaft, and the other end of fixed part is fixed on the end of interconnecting piece.
In this configuration, air can generate bigger wind pressure at pedestal, and help improves air quantity.
This draught fan impeller compared with the prior art, since pedestal and fan blade are an integral structure, and for aluminium alloy compression casting at
Type, therefore its structure is relatively stable.

Specific embodiment
It is specific embodiment of the utility model and in conjunction with attached drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these examples.
As shown in Figure 1 to Figure 3, this draught fan impeller includes pedestal 1 and the fan blade being distributed in around pedestal 12.The number of fan blade 2
Amount is seven and is evenly distributed on around pedestal 1.Pedestal 1 and fan blade 2 are an integral structure, and the material of pedestal 1 and fan blade 2 is aluminium
Alloy, and pass through die cast.
Specifically, pedestal 1 includes shaft 11 and the interconnecting piece 12 on the outside of shaft 11 annular in shape, fan blade 2 connects
It connecing in 12 outside of interconnecting piece, the fixed part 14 of sheet is equipped between shaft 11 and interconnecting piece 12, fixed part 14 is obliquely installed, and
One end of fixed part 14 is fixed in shaft, and the other end of fixed part 14 is fixed on the end of interconnecting piece 12.It is fixed in Fig. 3
The lower end in portion 14 is fixed at the lower end of interconnecting piece 12.In this configuration, air can generate bigger wind at pedestal 1
Pressure, help improve air quantity.
There is groove 13 perpendicular to 11 axis of shaft and in a strip shape in shaft 11.The setting of groove 13, facilitates electricity
Machine shaft is inserted into rear pin shaft positioning, so that draught fan impeller is using more convenient.
In addition, 1 edge of pedestal is evenly distributed with multiple recesses 15 close to the position of fan blade 2.It is distributed on 1 edge of pedestal recessed
Mouth 15, so that draught fan impeller is during the work time, can generate biggish wind pressure by the air at recess 15, help to improve
Air quantity.
In this draught fan impeller, since pedestal 1 and fan blade 2 are an integral structure, on the one hand reduce assembly process, so that
Production efficiency is higher, on the other hand, but also the structural integrity of pedestal 1 and fan blade 2 as a whole is preferable, improves blower leaf
The structural stability of wheel.In addition, the material of pedestal 1 and fan blade 2 is aluminium alloy, but also draught fan impeller is in use, no
It is also easy to produce spark, use is safer, and use scope is wide.
