Abstract
The utility model relates to an axial-flow blower impeller by utilizing an assembly blade wheel disk. A blade wheel disk which is sleeved on a hub is formed by splicing a plurality of blade wheel disk sections. Two side edges of each blade wheel disk section are respectively provided with a tenon and a mortise, the tenon on each blade wheel disk section is embedded inside the mortise on the adjacent blade wheel disk section, so the adjacent blade wheel disk sections are sleeved and spliced with each other to form a complete wheel disk. The center of each blade handle is provided with a connecting hole; mounting holes of the blade handles are uniformly distributed on a blade handle mounting disk, and the position of each mounting hole corresponds to the connecting hole on the blade handle. The edge on the outer circle of a spoke disk is uniformly provided with hub connecting holes which join the spoke disk with the hub 4, and the edge on the inner circle of the spoke disk is uniformly provided with blade handle connecting holes which join the spoke disk with the blade handles. Due to adoption of the axial-flow blower impeller, the production cost is reduced, the consistence of the processing precision and strength of the blade wheel disk is improved, and the reliability and the processing precision of the blade wheel disk are improved. By utilizing the axial-flow blower impeller, the fan blades can be conveniently replaced on the site, and the service life of a blower can be prolonged.
Description
Technical field
What the present invention relates to is the blower fan field, is a kind of axial flow fan vane wheel that adopts the made up turbine disk.
Background technique
Blower fan is ventilation equipment, and axial-flow blower is the blower fan that a class is important and amount is big, and a large amount of axial-flow blowers that use are brought into play its dust removal by ventilation effect in colliery, mine, tunnel, chemical industry, the energy, textile industry.
How closely related with the performance of draught fan impeller the performance of axial-flow blower is.Draught fan impeller generally is made up of parts such as one group of blade, turbine disk, wheel hub, spoke dishes, and its core component is blade and turbine disk.For the core component processing of draught fan impeller, prior art has two kinds of methods, and a kind of is the split processing method, and another is whole processing method.
The split processing method is blade and the turbine disk that processes earlier each monomer respectively, and then the blade of each monomer is welded on the turbine disk.The deficiency of split processing method is: (a) because one group of a plurality of blade is welded on the turbine disk, this relates to a plurality of blade conformity welding location, so just be difficult for making the welding accurate positioning of a plurality of blades, thereby the design performance of blower fan is descended, descend as fan efficiency and blower ventilation amount; (b) welding procedure is difficult to guarantee the weld strength and the conformity of each blade; (c) when certain blade damage, be difficult to blade be changed at the blower fan scene.
Whole processing method, be that one group of blade and turbine disk are carried out cast inblock, though this method can accomplish to make the conformity location of a plurality of blades on turbine disk in a group, but whole processing method has caused other deficiency, show as: (a) because one group of a plurality of blade has the stereo-overlap part on turbine disk, make cast-in-block mould manufacture difficulty big like this, especially be difficult to withdrawing pattern in casting process; (b) need adopt smart casting to the cast inblock of blade and turbine disk, precision casting mould is the cost height not only, and owing to withdrawing pattern difficulty in casting process is big, so the yield rate of cast inblock processing is not high; (c) when certain blade damage, can't change blade at the blower fan scene, can only change whole blade wheel disc and whole blades, operation maintenance expense like this is high.
Summary of the invention
In order to overcome above-mentioned split processing method and whole processing method to the deficiency in the processing of blade and turbine disk, the present invention proposes a kind of axial flow fan vane wheel that adopts the made up turbine disk.
The present invention includes wheel hub, blade, petiole and turbine disk, it is characterized in that, the blade lobe consists of one by blade, tenon, petiole, attachment hole and tongue-and-groove, and global formation.There is the petiole mounting disc of radially protruding at the wheel hub middle part; Blade pass is crossed petiole and is fixed in the petiole mounting disc of wheel hub; Two spoke dishes are sleeved on the wheel hub and are positioned at the both ends of the surface of petiole mounting disc.Turbine disk is sleeved on the wheel hub; Turbine disk is to be spliced by a plurality of turbine disk lobes.Dual-side at the turbine disk lobe has tenon and tongue-and-groove respectively, and the tenon on each piece turbine disk lobe all embeds in the tongue-and-groove on another adjacent piece turbine disk lobe, and socket is assembled into complete turbine disk mutually.At each petiole center attachment hole is arranged; Uniform petiolate mounting hole in the petiole mounting disc, the position of this mounting hole is corresponding with petiolar attachment hole.Be evenly distributed with the wheel hub attachment hole that this spoke dish is connected with wheel hub at the outer circular edge place of spoke dish, be evenly distributed with the petiole attachment hole that this spoke dish is connected with petiole at the internal circle edge place of spoke dish.
The external diameter of the petiole mounting disc on the external diameter of two spoke dishes and the wheel hub is identical.
Because the technological scheme that the present invention takes, accomplished the conformity of blade lobe machining accuracy and intensity, become turbine disk by blade lobe joggle again, compare with impeller split processing method and whole processing method, its processing charges greatly reduce, and reliability and machining accuracy greatly improve, and can also obviously reduce production costs, conveniently replaced at the scene fan blade, thus working life of blower fan prolonged.
