Abstract
The utility model discloses an impeller of a forward multi-vane centrifugal fan, which is an integral vane combined body. The integral vane combined body is provided with a whole plate, two ends of the whole plate are welded into a wheel-shaped body, and a vane which is formed with the whole plate into an integral body is evenly arranged on the whole plate. A structure is simple, the wheel-shaped body of the vane forms an integral type, and all the vanes are formed on the integral plate by punching. An additional connecting structure does not exist between the vane and the integral plate, and the utility model has the advantages of small blower vibration, low noise, high work efficiency and low cost and can not generate surplus waste materials.
Description
Technical field:
The utility model relates to a kind of draught fan impeller.
Background technique:
Existing forward multiple wing centrifugal fan impeller, blade is the every all independent form that is connected with forward and backward dish, during manufacturing, need a slice a slice processing blade, the manufacture cost height, waste of material, and blade is to adopt on the dish of front and back jack is set with being connected of front and back dish, the two ends of blade are provided with insert head, before and after blade inserts behind the sheet,, be connected with front and back dish riveted type with insert head knock rivet-like one by one, such Placement, easily loosening, undesirable in conjunction with soundness, cause fan vibration big, noise is big, inefficiency.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and the wheel-shaped body of blade is integrated type, and fan vibration is little, and noise is little, the impeller of the forward multiple wing centrifugal ventilator of high working efficiency.
Technical solution of the present utility model is:
A kind of impeller of forward multiple wing centrifugal ventilator is characterized in that: be the integral blade assemblying body, the integral blade assemblying body has integral slab, and the integral slab two ends are welded to connect into wheel-shaped body, and the blade of the form that is integral with integral slab evenly is set on the integral slab.
The wheel-shaped body both sides are the bending body form.In the wheel-shaped body both sides forward and backward dish is set, the subsumption architecture that is connected with the bending body containment type of wheel-shaped body both sides is set on the forward and backward dish.
The utility model is rational in infrastructure, and the wheel-shaped body of blade is integrated type, and all blades are stamped to form on an integral slab, do not have additional linkage structure between blade and the integral slab, fan vibration is little, and noise is little, high working efficiency, and cost of production is low, can not produce unnecessary waste material.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an embodiment's of the utility model a configuration diagram.
Fig. 2 is the unfolded drawing of integral slab.
Fig. 3 is the left view of Fig. 2.
A kind of impeller of forward multiple wing centrifugal ventilator is the integral blade assemblying body, and the integral blade assemblying body has integral slab 1, and integral slab 1 two ends are welded to connect into wheel-shaped body, and the blade 2 of the form that is integral with integral slab evenly is set on the integral slab 1.The wheel-shaped body both sides are bending body 3 forms.Forward and backward dish 4,5 is set in the wheel-shaped body both sides, the subsumption architecture 6 that is connected with bending body 3 containment types of wheel-shaped body both sides is set on the forward and backward dish 4,5.The telophragma 7 that is connected with blade also can be set between forward and backward dish.
The utility model can also have other suitable embodiments, and example is not established forward and backward dish, telophragma etc.
