The fan is used for developing new products, and can also transform the existing products such as T35, T30, T40, GD30K4, SJG, SWF and other series of axial-flow and mixed-flow fans.
Description
Affiliated technical field
The utility model belongs to the ventilating machinary apparatus field, and being specifically related to is the impeller of a kind of axial flow, mixed flow ventilator.
Background technique
Axial flow, mixed flow fan are widely used in chemical industry, metallurgy, weaving, oil, refrigeration, air-conditioning, factory building, kitchen, warehouse, office's ventilation for residences ventilation.At present T35, T30, T40, GD30K4, serial blower fan such as SJG, SWF use extensivelyr, and its wheel hub is steel structure, and blade is a single panel type, adopt the form of welding to be connected mostly between blade and the wheel hub, make it simple in structure, easy to manufacture.Because wheel hub adopts steel structure, weight is big, has therefore increased load to spring bearing; It is to be welded as the master with manual operations mostly that blade is connected with wheel hub, and welded structure easily produces distortion, and manufacturing efficiency is low, and maintenance is inconvenient.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of above-mentioned technology, axial flow, mixed flow fan impeller a kind of simple in structure, in light weight, easy for installation to be provided.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: the impeller of a kind of axial flow, mixed flow ventilator, it is characterized in that wheel hub is that two one end faces by die casting are ladder-type, the cylindrical body that its ladder-type male and female face is formed relatively, blade is a board-like unit camber, its root and ladder-type are corresponding, be installed between the male and female face, being fixedly clamped by fastening piece is connected on the wheel hub.
Blade of the present utility model also is board-like meander configuration; The blade quantity that is fixedly connected on the wheel hub can be the 2-11 sheet; Wheel hub can be Rotary-table; The side of wheel hub also can be circular arc; The ladder number of wheel hub is the 1-7 rank.
The beneficial effects of the utility model are that simple in structure, in light weight, easily manufacturing can realize producing in batches, and is easy for installation.Be used for the exploitation of new product, but also can transform existing product such as T35, T30, T40, GD30K4, serial axial flow, mixed flow ventilators such as SJG, SWF.

Embodiment
As seen from Figure 1, Figure 2, the impeller of a kind of axial flow, mixed flow ventilator, form by wheel hub, blade, fastening piece three parts, wheel hub is that two one end faces by die casting are ladder-type, the cylindrical body that its ladder-type male and female face is formed relatively, blade is a board-like unit camber, its root and ladder-type are corresponding, be installed between the male and female face, being fixedly clamped by fastening piece is connected on the wheel hub.The wheel hub die cast generally adopts aluminum alloy to make, and is in light weight, produces the efficient height in batches by transfer mold; Blade is board-like unit camber, and is simple in structure, and available blanking die, press-moulding die are produced in batches; Fastening piece can be selected rivet or bolt for use, and technology is simple, the manufacturing efficiency height.
Blade of the present utility model is the board-like meander configuration that is, and the blade quantity that is fixedly connected on the wheel hub is the 2-11 sheet; Wheel hub can be Rotary-table, also but the side is circular arc, and the ladder number of its end face is the 1-7 rank.
Fig. 3 is that the ladder number is the cylindrical body wheel hub on 2 rank, and this wheel hub can be made into symplex structure, can be made by a cover transfer mold, saves die cost, and cost of production is low.The root of blade distortion for a long time of the optional 1-7 of wheel hub ladder number rank, ladder number is little, and can be used for the series of blade broad.
Fig. 4 is to be the blade that the wheel hub on 2 rank matches with the ladder number.Lobe numbers can be selected the 2-11 sheet for use, when selecting the duralumin, hard alumin ium alloy blade for use, can be used for the explosion proof and corrosion protection occasion.
Fig. 5 is that root of blade is the section that 2 rank types match with wheel hub ladder number.
Wheel hub shown in Figure 6 is a Rotary-table.Fig. 7 wheel hub side is circular arc.These two kinds of structures all need to make with 2 cover die casting moulds.
Root of blade of the present utility model is pressed into ladder-type by mould, wheel hub is formed by aluminium alloy compression casting, the end face rheo-die-casting becomes ladder-type, between the concavo-convex relative ladder, blade is installed, after root of blade entered, fastening to be connected with rivet or bolt clip promptly became axial flow, mixed flow fan impeller on the wheel hub.
