Description

Axial flow fan vane wheel anti-deforming structure

Technical field

The utility model relates to axial flow fan vane wheel technical fields, in particular to axial flow fan vane wheel anti-deforming structure.

Background technique

Axial flow blower is called booster, is a kind of industrial and mining enterprises' commonly blower, but be different from general blower it Motor and fan blade all in a cylinder, shape is exactly a tubular, be used for local ventilation, it is easy for installation, ventilation effect Fruit is obvious, and safety, the cylinder that can give a dinner for a visitor from afar, which is kept watch, is sent to specified region.Annealing furnace, homogeneous furnace are usually using axial flow blower, and axis stream Blower, which will increase service life, must be heat-treated to eliminate stress, but it is raised to be easy to produce impeller disc during heat treatment The phenomenon that, necessary back-pressure returns original in processing, and peripheral weld will certainly be made to generate other power, has safety hidden in use Suffer from.In order to solve this problem prior art is to add reinforcing rib in impeller to force to reinforce the change in impeller heat treatment process Shape, complex process, increased costs, service life are not grown.And the disc of the utility model impeller is a kind of conical banda groove part The structure of reinforcement prevents from deforming, simple process, and cost reduces, and the service life of impeller increases.

Utility model content

In order to overcome the high-temperature axial flow fan that non-ferrous metal industry uses in the prior art to be easy to make during heat treatment Impeller disc generates raised deformation, and a kind of special structure of conical banda groove local strengthening of utility model prevents the defect of deformation, The utility model provides axial flow fan vane wheel anti-deformation device.

To achieve the goals above, the utility model the following technical schemes are provided:

Axial flow fan vane wheel anti-deforming structure, including taper reinforce disc, wheel hub, small stiffening plate, cylinder, blade and recessed Slot, it is pyramidal structure plate that the taper, which reinforces disc, and conehead is provided with through-hole, is installed on wheel hub, and the wheel hub is equipped with two The opposite taper of block conehead reinforces disc, and the taper is reinforced being fixed on cylinder on the outside of disc, if being equipped on the outside of the cylinder Cured leaf piece；The taper reinforces disc and is uniformly provided with six grooves at outer circle, and the opening direction of groove reinforces spoke towards taper The conical inner side of plate fixes a small stiffening plate on each groove.

Further, the groove is long hole, and the small stiffening plate of upper part is rectangular slab, and the length of the small stiffening plate is roomy In the size of groove, the small stiffening plate is fixed on the outside of groove by the connection type welded.

Further, the taper reinforces disc by mold extrusion forming, with wheel hub and cylinder all using welded connecting.

Beneficial effect brought by the utility model is: original impeller disc is changed to taper reinforcement spoke with groove Plate disperses disc deformation force in heat treatment, is not to deform disc, while reinforcing the groove welding of disc in taper Small stiffening plate increases disc intensity；Impeller sets two pieces of taper disc up and down, forms hollow cavity among impeller, keeps impeller whole Body enhanced strength；By change disc, it is not easy to deform impeller during heat treatment, the disc processing technology is simple, at This reduction increases impeller service life.

Specific embodiment

The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear Define.

As shown in Figure 1-3, axial flow fan vane wheel anti-deforming structure, including taper reinforce disc 1, wheel hub 2, small stiffening plate 3, Cylinder 4, blade 5 and groove 6, it is pyramidal structure plate that the taper, which reinforces disc 1, and conehead is provided with through-hole, is installed on wheel hub 2 On, the wheel hub 2 is equipped with the opposite taper of two pieces of coneheads and reinforces disc 1, and the taper is reinforced being fixed on cylinder on the outside of disc 1 On 4, upper and lower two pieces of tapers are reinforced forming a hollow cavity between disc 1 and wheel hub 2 and cylinder 4, increase impeller entirety Intensity；Several blades 5 are equipped on the outside of the cylinder 4, blade 5 is the Pneumatic assembly on impeller, the band movable vane piece 5 in impeller rotation Generate air-flow；The taper reinforces disc 1 and is uniformly provided with six grooves 6 at outer circle, reinforces disc 1 in taper and is heat-treated the time-division Deformation force is dissipated, disc is unlikely to deform；The opening direction of groove 6 reinforces the conical inner side of disc 1, each groove 6 towards taper On fix one small stiffening plate 3, increase the intensity of disc, more further make taper reinforce disc 1 it is indeformable.

The groove 6 is long hole, and the small stiffening plate 3 of upper part is rectangular slab, and the length of the small stiffening plate 3 is wider than groove 6 size, the small stiffening plate 3 are fixed on 6 outside of groove by the connection type welded.

The taper reinforces disc 1 by mold extrusion forming, with wheel hub 2 and cylinder 4 all using welded connecting.

The present invention will be further described with working principle with reference to the accompanying drawing.

Impeller includes that taper reinforcement disc 1, wheel hub 2, small stiffening plate 3, cylinder 4 and blade 5, wheel hub 2 are connected with main shaft, is taken turns It is welded with two pieces of tapers on the outside of hub 2 and reinforces disc 1, taper is reinforced disc 1 and is welded on cylinder 4, blade 5 is welded on the outside of cylinder 4, It drives entire impeller to rotate by wheel hub 2 when main shaft rotates, and the torque of main shaft is transferred on blade 5 by disc, impeller Band movable vane piece 5 generates air-flow when rotation；

Taper reinforces disc 1 and is pressed into taper by mold, and is making a call to six grooves 6 at outer circle, and groove can be such that taper adds Strong disc 1 disperses deformation force in heat treatment, makes disc be not to deform, while welding small stiffening plate 3 on groove 6, increases Taper reinforces the intensity of disc 1, is unlikely to deform it more；The taper reinforces disc 1 and is arranged two pieces, makes to be formed among impeller One cavity body, increases the integral strength of impeller.

Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to In this, anyone skilled in the art, can be without creative labor in the technical scope disclosed by the utility model The dynamic change or replacement expected, should be covered within the scope of the utility model.Therefore, the protection model of the utility model Enclosing be determined by the scope of protection defined in the claims.
