Abstract
The utility model relates to a centrifugal fan discloses centrifugal wind wheel, including a plurality of curved blades (1), be equipped with at least one fin (2) between blade (1). The utility model discloses simple structure, simple to operate through set up fin (2) between blade (1), prevents that the air current from forming the swirl at ye daozhong to promote the wind wheel performance, avoid the swirl to cause the friction to blade (1), reduce the life of blade (1), strengthened the impact capacity of the anti air current of wind wheel, improved the work efficiency of wind wheel, reduced the noise of wind wheel work simultaneously.
Description
Technical field
The utility model relates to centrifugal blower, particularly relates to a kind of centrifugal wind wheel be arranged in centrifugal blower.
Background technique
Centrifugal wind wheel, namely the impeller in centrifugal blower is arranged on, impeller central is suction port, when impeller rotates under power equipment drives, air is sucked from suction port, vane rotary process applies dynamic action simultaneously, improves pressure and the speed of gas, and gas is discharged along the leaf road relief opening between impeller Leaf under the influence of centrifugal force.Existing centrifugal wind wheel blade is the blade of arc, when air-flow is got rid of from the leaf road between blade, easy formation whirlpool, a part of air-flow is caused to spin between the blades, reduce the working efficiency of wind wheel, and produce friction between whirlpool and blade, cause the temperature of blade to raise, reduce the working life of blade.
Summary of the invention
The utility model easily produces whirlpool shortcoming between prior art Leaf, provides a kind of centrifugal wind wheel eliminating whirlpool.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Centrifugal wind wheel, comprises the blade of multiple arc, is provided with at least one fin between blade.By arranging fin between the blades, fin is beaten and spreads the whirlpool produced between blade, promote that air flow energy is discharged from the leaf road between blade smoothly, improve the working efficiency of wind wheel, prevent from whirlpool and blade from producing to rub, improve the heat of blade, extend the working life of blade, avoid because whirlpool produces noise.
As preferably, also comprise shroud, the quantity of blade and fin is for being 7 and being uniformly arranged on shroud.Blade and fin is uniform is arranged on shroud, ensure that the uniformity of airflow, improves the working efficiency of wind wheel while reducing gas shock.
As preferably, also comprise hub disk, the lower end of blade is connected with hub disk.Increase between blade by force intensity, ensure that air-flow flows out from stable between blade.
As preferably, fin is located at the outward edge of shroud.Make fin can block the periphery of whirlpool, prevent air-flow from forming whirlpool.
As preferably, the height of fin is equal with the height of blade.When wind-force is larger, when the height of fin is less than blade, air-flow easily forms whirlpool at the height difference place of fin and blade, prevents the leaf road between blade from forming whirlpool, air flow energy is discharged along fin time highly equal.
As preferably, the height of fin is less than the height of blade.When wind-force is less, reduce the manufacture cost of wind wheel, increase the flow of air-flow, improve the working efficiency of wind wheel.
As preferably, fin lower ends is provided with sawtooth.Sawtooth plays the effect of breaing up air flow swirl, prevents air-flow from forming whirlpool in fin lower ends.
As preferably, the lower end of blade is provided with buckle, and hub disk is connected on blade by buckle.Dismounting and the replacing of hub disk is prevented when later period maintenance or cleaning.
The utility model is owing to have employed above technological scheme, there is significant technique effect: structure is simple, easy for installation, by arranging fin between the blades, preventing air-flow from forming whirlpool at Ye Daozhong, avoiding whirlpool to cause friction to blade, reduce the working life of blade, enhance the impact capacity of the anti-air-flow of wind wheel, improve the working efficiency of wind wheel, reduce the noise of wind wheel work simultaneously.
