Abstract
The invention relates to a blower impeller, particularly a sintering centrifugal blower impeller. The sintering centrifugal blower impeller at least comprises left and right shaft discs (1), left and right cover discs (3), a wheel disc (5) and left and right blades (4), wherein the left and right shaft discs (1) are combined and then form a clamping groove with a matched thickness with the wheel disc (5), the wheel disc (5) is clamped in the clamping groove, a bolt (6) penetrates through via holes on the two sides of the clamping groove and a via hole of the wheel disc (5) and then can be fastened by a nut (7); left and right cavities can be formed between the wheel disc (5) and the left and right cover discs (3), and the left and right blades (4) are respectively fixed in the left and right cavities.
Description
Technical field
The present invention relates to a kind of blower wheel, is a kind of sintering centrifugal blower impeller exactly.
Background technique
The sintering centrifugal blower is an indispensable part in the sintering coke making process process; Characteristics are that fed sheet of a media is a sinter fume; Pressure is between 10Kpa～20Kpa, import volume flow broad covered area, and rotating speed is not more than 1500r/min; Impeller diameter is more than 2000mm, and blade adopts plate or backward bending type.
Along with improving day by day of industrial economy, the maximization of unit and the requirement of high efficiency are increased thereupon.The traditional drum draught fan impeller can not satisfy the demand of the national economic development now far away.
Summary of the invention
The purpose of this invention is to provide a kind of efficient height, meet the sintering centrifugal blower impeller that gas flows naturally in solid of rotation.
The objective of the invention is to realize like this; Sintering centrifugal blower impeller; It is characterized in that: comprise left and right sides reel, left and right sides shrouding disc, wheel disc, left and right sides blade at least, left and right sides reel merges the back and forms the holding tank that thickness matches with wheel disc, and wheel disc is clamped in the holding tank; Bolt passes the via hole and the wheel disc via hole of holding tank both sides, tightens up through nut again.Between wheel disc and left and right sides shrouding disc, form left and right sides cavity, left and right sides blade is separately fixed in the cavity of the described left and right sides.
Left and right sides blade is the three-dimensional flow structure.
The left side of interior inside edge of left and right sides blade and wheel disc or right side welding; The welding of left and right sides blade outermost outer edge and shrouding disc inside edge, the left and right sides makes reel, left and right sides shrouding disc, wheel disc, left and right sides blade form the impeller of two groups of one, impeller axial admission; Radially exhaust, axially with radially between the transition of formation cambered surface.
Axially with radially between form the cambered surface place formation that cambered surface is reel and left and right sides shrouding disc in the left and right sides, narrow above wide below the reel of the left and right sides, formation air inlet through hollow shaft sectional area is big, radially the air-out sectional area is little.
Advantage of the present invention is: owing to see that on the whole impeller is made up of left and right sides structure, left and right sides structure forms back-to-back through wheel disc and connects.Say it is left and right sides axial admission from intake method, exhaust then is and radially exhaust of type.Axially with radially between the transition of formation cambered surface.Left and right sides blade adopts and meets gas design of mobile characteristic naturally in solid of rotation, obviously cuts down the consumption of energy when the impeller adiabatic efficiency of production improves greatly.Make impeller adiabatic efficiency directly bring up to 90% from 81%, the effectively optimizing property of blade profile makes the overall structure of impeller that variation take place, and the most significantly the shrouding disc form has the square position to become the arc dish, and blade profile becomes changeful curvature by single-curvature.
Below in conjunction with embodiment's accompanying drawing the present invention is described further:
Description of drawings
Fig. 1 is an embodiment of the invention structural representation;
Fig. 2 is the side schematic view of Fig. 1.
Among the figure, 1, reel; 2, Kou Quan; 3, shrouding disc; 4, blade (positive 32 pieces of circumference uniform distributions of anti-communism); 5, wheel disc; 6, bolt; 7, nut.
Concrete real mode
Like Fig. 1, shown in Figure 2; Sintering centrifugal blower impeller; At least comprise left and right sides reel 1, left and right sides shrouding disc 3, wheel disc 5, left and right sides blade 4, left and right sides reel 1 merges the back and forms the holding tank that thickness matches with wheel disc 5, and wheel disc 5 is clamped in the holding tank; Bolt 6 passes the via hole and wheel disc 5 via holes of holding tank both sides, tightens up through nut 7 again.Between wheel disc 5 and left and right sides shrouding disc 3, form left and right sides cavity, left and right sides blade 4 is separately fixed in the cavity of the described left and right sides.
Left and right sides blade 4 designs for three-dimensional flow; A left side or the right side welding of left and right sides blade 4 interior inside edges and wheel disc 5; Weld left and right sides blade 4 outermost outer edges and shrouding disc inside edge, the left and right sides, makes the impeller of reel 1, left and right sides shrouding disc 3, wheel disc 5, two groups of one of left and right sides blade 4 formation, the impeller axial admission; Radially exhaust, axially with radially between the transition of formation cambered surface.
Axially with radially between form the cambered surface place formation that cambered surface is reel 1 and left and right sides shrouding disc 3 in the left and right sides; This just requires Y-axis dish 1 time narrow above the face width, and it is big to form the air inlet through hollow shaft sectional area, and radially the air-out sectional area is little; Excessive and the three-dimensional flow left and right sides blade 4 of while cambered surface; The air intake resistance is reduced, improve the efficient of impeller, make impeller adiabatic efficiency directly bring up to 90% from 81%.
See that on the whole impeller is made up of left and right sides structure, left and right sides structure forms back-to-back through wheel disc 5 and connects.Say it is left and right sides axial admission from intake method, exhaust then is and radially exhaust of type.
