Description
Technical field
The utility model belongs to centrifugal blower field, specifically, more particularly to a kind of high temperature wind with bracing means
Machine.
Background technique
When draught fan impeller under conditions of hot environment (500 DEG C) in use, the draught fan impeller of most series can use
, there is blade wheel structure damage or deformation, sternly under the action of high temperature and centrifugal force in the process due to self structure intensity the problem of
The service life of draught fan impeller under hot environment is affected again.
Summary of the invention
The purpose of this utility model is to provide a kind of high-temperature blowers with bracing means, can be realized 500 DEG C of height
The improvement of fan impeller structure intensity under warm environment, improves the service life of impeller.
In order to achieve the above objectives, the utility model is achieved through the following technical solutions:
The high-temperature blower of bracing means, including shroud, blade and hub disk are had described in the utility model, wherein described
Blade be fixedly connected respectively with shroud and hub disk, it is characterised in that: the shroud is relative to being welded with reinforcing on the outside of blade
Circle and mouth circle；The intermediate openings of the blade and be welded at adjacent blade openings it is intermediate reinforce disk body, centre reinforces
The inside of disk body is integral (type) flange circle；The hub disk is fixed with outer ring relative to the side of blade, at the central axes of the hub disk
Reel is installed, is connected with longitudinal rib between outer ring, hub disk and reel.
Further speaking, the link position of reel described in the utility model and hub disk is by rivet interlacement, at rivet
Rivet reinforcing member is installed.
Further speaking, fixing collar described in the utility model is located at the outside of mouth circle, the connection of mouth circle and fixing collar
Position is in 90 °.
Compared with prior art, the utility model has the beneficial effects that
The utility model realizes fan impeller structure in a high temperauture environment by the reinforcing to shroud, blade and hub disk
Intensity avoids the deformation and damage of fan impeller under high temperature and centrifugal force double action, improves the use with raising fan impeller
Service life.

Specific embodiment
Technical solution described herein is described further with reference to the accompanying drawings and embodiments.
Embodiment 1: a kind of high-temperature blower with bracing means, shroud 3, leaf including constituting high-temperature blower primary structure
Piece 4 and hub disk 6, blade 4 are equipped with reel 9 at the 6 axis line position of hub disk between shroud 3 and hub disk 6；Preceding
Disk 3 is welded with mouth circle 1 relative to the side of blade 4, and the outside of mouth circle 1 and fixing collar 2 weld, and fixing collar 2 and shroud 3 are fixed,
Angle in 90 ° at the link position of mouth circle 1 and fixing collar 2.Intermediate reinforcing disk body 5 is welded with after the intermediate openings of the blade 4,
It is integral (type) flange circle that centre, which reinforces disk body 5,.The hub disk 6 is welded with outer ring 7, outer ring 7, hub disk 6 relative to the outside of blade 4
It is connected between reel 9 using radial rib 8.
Embodiment 2: a kind of high-temperature blower with bracing means is connected between hub disk 6 and reel 9 using rivet 10,
Rivet reinforcing member 11 is installed at the link position of rivet 10.The structure and connection relationship and any previous embodiment of rest part
Described in structure and connection relationship it is identical.
In view of above-described embodiment, when in use, the course of work and principle are as follows by the application:
The application claimed is a kind of high-temperature blower with bracing means, as shown in Figure 1, it is mainly in shroud
3, it is reinforced at three positions of blade 4 and hub disk 6, to guarantee that high-temperature blower is able to extend use under conditions of 500 DEG C
Service life avoids the problem that draught fan impeller deformation or damage occurs due to self structure intensity.
Firstly, being welded with mouth circle 1 relative to the side of blade 4 in shroud 3, mouth circle 1 is to be distributed around 9 central axis of reel
Circle body structure is welded on shroud 3, and has a fixing collar 2 in the outside weldings of mouth circle 1, fixing collar 2 respectively with mouth circle 1 and
Shroud 3 welds.Fixing collar 2 and mouth circle 1 have intensity it is high, can operational degree be high, does not influence the pneumatic property of shroud 3.
Secondly, being machined with opening on the blade 4 being distributed between shroud 3 and hub disk 6, the opening is for welding centre
Disk body 5 is reinforced, it is whole flange coil structures that centre, which reinforces disk body 5, can effectively solve the problem that blade 4 as caused by centrifugal force
The problem of bending deformation.
Third, position that another in the application is reinforced are hub disk 6, and the reinforcement operation of hub disk 6 is mainly by outer ring 7 and radial
Muscle 8 forms, and specifically, the central axis of outer ring 7 is overlapped with the central axis of reel 9, and the outer ring 7 is welded on hub disk 6
On, it is fixed between outer ring 7 and hub disk 6, reel 9 using radial rib 8, and radial rib 8 is welded on hub disk 6.
The mode connected between hub disk 9 and hub disk 6 described herein using rivet 10 is connected in rivet 10
Rivet reinforcing member 11 is installed, the thermal expansion that rivet reinforcing member 11 can be effectively improved between reel 9 and hub disk 6 is different at position
The problem of cause.
