Description
Technical field
The utility model relates to a kind of centrifugal blower fan blade wheel.
Background technique
Along with the propelling of China's process of industrialization, the positive Efforts To Develop of industrial trade is saved energy and reduce the cost, and centrifugal blower, as the important corollary equipment of industry, has been widely used in the fields such as electric power, cement, petrochemical industry, coal, mine and environmental protection.And draught fan impeller is as a key component of blower fan, whether its vibrational power flow rationally directly affects the overall performance of blower fan.The centrifugal blower fan blade wheel occurred on the market at present, mostly designs complexity, cost is high, efficiency is low, noise is high, not environmentally, not energy-conservation, working life is short, be not suitable for promoting the use of on a large scale.
Summary of the invention
The utility model mainly solves the technical problem existing for prior art, thus provide that a kind of simplicity of design, cost are low, efficiency is high, noise is low, environmental protection and energy saving, sound construction, long service life, practical centrifugal blower fan blade wheel.
The utility model is a kind of centrifugal blower fan blade wheel, comprises hub disk, shroud, steel pipe, blade and reel; Described reel is arranged on hub disk central position; Described blades installation is at shroud, between hub disk and diversion disk; Be provided with diversion disk outside described reel, diversion disk inserts blade interior, and diversion disk welds with hub disk, blade stagger; Described penstock installation is in the outside of reel, and the outside of steel pipe is provided with the stiffening plate of more than 3; One end of described steel pipe is connected with hub disk, and the other end is connected with diversion disk; One end of described reel is connected with hub disk, and the other end is connected with steel pipe and diversion disk.
As preferably, described diversion disk is set to bore arcuate structure, and after air-flow enters impeller, air-flow changes that angle is less, and effectively can improve the air flow method of impeller inlet corner, air current flow is more smooth and easy, and therefore, blower fan loss is little, noise is low, energy-efficient.
As preferably, described steel pipe is arranged between the osculum of diversion disk and hub disk, and the outside of steel pipe is provided with some stiffening plates, adds the intensity of impeller.
As preferably, the external diameter of described diversion disk is greater than shroud import, and inserts blade interior, and its staggered weld further enhances the safety reliability of impeller.
The beneficial effects of the utility model are: described diversion disk is set to cone arc diversion disk, and after air-flow enters impeller, it is less that air-flow changes angle, effectively can improve the air flow method of impeller inlet corner, air current flow is more smooth and easy, therefore, blower fan loss little, noise is low, energy-efficient; Described steel pipe is arranged between the osculum of diversion disk and hub disk, adds the intensity of impeller; The external diameter of described diversion disk is greater than shroud import, and inserts blade interior, and its staggered weld further enhances the safety reliability of impeller.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the plan view of a kind of centrifugal blower fan blade wheel of the utility model.
Fig. 2 is the sectional view of a kind of centrifugal blower fan blade wheel of the utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
A kind of centrifugal blower fan blade wheel as shown in Figure 1 and Figure 2, comprises hub disk 1, shroud 6, steel pipe 5, blade 2 and reel 4; Described reel 4 is arranged on hub disk 1 central position; Described blade 2 is arranged on shroud 6, between hub disk 1 and diversion disk 3; Be provided with diversion disk 3 outside described reel 4, it is inner that diversion disk 3 inserts blade 2, and diversion disk 3 interlocks weld with hub disk 1, blade 2; Described steel pipe 5 is arranged on the outside of reel 4, and the outside of steel pipe 5 is provided with the stiffening plate 7 of more than 3; One end of described steel pipe 5 is connected with hub disk 1, and the other end is connected with diversion disk 3; One end of described reel 4 is connected with hub disk 1, and the other end is connected with steel pipe 5 and diversion disk 3.
Described diversion disk 3 be set to bore arcuate structure, after air-flow enters impeller, air-flow change angle less, air current flow is more smooth and easy, therefore, blower fan loss little, noise is low, energy-efficient.
Described steel pipe 5 is arranged between the osculum of diversion disk 3 and hub disk 1, and the outside of steel pipe 5 is provided with some stiffening plates 7, adds the intensity of impeller.
The external diameter of described diversion disk 3 is greater than shroud 6 import, and it is inner to insert blade 2, and its staggered weld further enhances the safety reliability of impeller.
The beneficial effects of the utility model are: described diversion disk be set to bore arcuate structure, after air-flow enters impeller, air-flow change angle less, air current flow is more smooth and easy, therefore, blower fan loss little, noise is low, energy-efficient; Described steel pipe is arranged between the osculum of diversion disk and hub disk, and the outside of steel pipe is provided with some stiffening plates, adds the intensity of impeller; The external diameter of described diversion disk is greater than shroud import, and inserts blade interior, and its staggered weld further enhances the safety reliability of impeller.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
