Description

Dust catcher impeller
Technical field
The present invention relates to cleaner field, more particularly to a kind of dust catcher impeller.
Background technology
The direction flowed by gas, blower fan classification can be divided into the types such as centrifugal, axial-flow type, diagonal flow type and cross-flow type. When centrifugal blower works, engine driving impeller is rotated in volute casing, and air is sucked through air entry at impeller central.By In dynamic action of the blade to gas, gas pressure and speed are improved, and are got rid of under the action of the centrifugal force along Ye Dao to machine Shell, from exhaust outlet discharge.
Centrifugal blower air quantity, blast scope are big, and noise is low, and centrifugal blower is pressed in being selected the blower fan used in dust catcher more. Impeller is the critical piece of blower fan, and its geometry, size, lobe numbers and the accuracy of manufacture has a significant impact to performance.Leaf Wheel just can guarantee that blower fan is smoothly rotated through static balance or dynamic balance calibration.By the difference in blade exit direction, before impeller is divided into To, radially and backward three kinds of patterns.The pressure that wherein forward direction impeller is produced is maximum, and the draught fan impeller in dust catcher is also before many uses To formula.
In actual product, impeller blade number is limited, and the air of certain space size can be formed between adjacent two blade Runner.When the impeller is rotated, air flow channel rotates with impeller together, because gas is sticky small, and the gas in air flow channel Body is due to its rest inertia, and the gas in air flow channel can produce relative revolution with air flow channel, also just generate axial eddy. The generation of axial eddy reduces the energy transformation ratio of blower fan, adds the radiating load and noise of blower fan.

Embodiment
Below by embodiment, the present invention is described in further detail, to make those skilled in the art with reference to specification Word can be implemented according to this.
It should be appreciated that used herein such as " have ", "comprising" and " comprising " term are not precluded from one or many The presence or addition of individual other elements or its combination.
Embodiment one
With reference to shown in Fig. 1-2, a kind of dust catcher impeller at least includes:Front shroud 100, it is disc structure, the front-wheel The middle part of lid 100 is provided with first through hole 110;Wheel cover 200, it is disc structure, and the edge of wheel cover 200 passes through a cylindrical shell The kuppe 210 of structure is fixedly connected with the outward flange of the front shroud 100, and some second are offered on the kuppe 210 Through hole 211;And blade 300, it is fixedly installed between the front shroud 100 and the wheel cover 200, the blade 300 Including some primary blades 310 and some splitterr vanes 320, the primary blades 310 are in the front shroud 100 radially from described One through hole edge is extended out to away from first preset distance of outward flange of front shroud 100, and the primary blades 310 are in the front-wheel Lid 100 extends to the front side wall of wheel cover 200 on axial direction from the rear wall of front shroud 100, and the primary blades 310 are described On the circumferencial direction of front shroud 100 self-retaining the first end of the front shroud 100 turn over first angle extend to be fixed on it is described Second end of wheel cover 200, the primary blades 310 are uniformly arranged, and the splitterr vanes 320 are set parallel to the primary blades 310 Put.The first angle is 90 degree.The design structure of the primary blades 310 so that the air flow channel that primary blades 310 are divided into Stroke becomes big, plays the air-flow for allowing impeller to produce more stable effect.
The splitterr vanes 320 are in the front shroud 100 radially from away from the preset distance of first through hole edge second Place is extended out to away from the preset distance of 100 outward flange of front shroud the 3rd, and the splitterr vanes 320 are in the front shroud 100 The front side wall of wheel cover 200 is extended to from the rear wall of front shroud 100 on axially, the splitterr vanes 320 are before described Self-retaining is extended to by first angle in the first end of the front shroud 100 and fixed in the rear on the circumferencial direction of wheel cap 100 Second end of wheel cap 200.The splitterr vanes 320 are uniformly arranged, on the splitterr vanes 320 and the quantity of primary blades 310 Correspond.3rd preset distance is less than first preset distance.The setting of the splitterr vanes 320, reduces master The air flow channel space of the formation of blade 310, reduces the generation of axial flow.
Embodiment two
The non-homogeneous arrangement of splitterr vanes 320, splitterr vanes 320 described in adjacent two groups with it is corresponding closest The spacing of the primary blades 310 is unequal.The splitterr vanes 320 and the spacing of the closest primary blades 310 be not small In 1/10th of the spacing of primary blades 310 described in adjacent two groups.The splitterr vanes 320 are by between the primary blades 310 Each air flow channel is cut, if air flow channel size formed by splitting is identical, air when air flow channel is exported because Similar motion state, easily produces resonance, produces larger noise, while reducing blower fan energy conversion efficiency.Therefore pass through Control the position of splitterr vanes 320 so that difference avoids above mentioned problem to the air flow channel being split to form, meanwhile, shunt leaf Piece 320 also cannot be too near apart from primary blades 310, and otherwise easy air easily produces howl when moving quickly through this narrow gap Cry, and be arranged such splitterr vanes 320 and also do not have the effect for preferably suppressing axial flow.
