Impeller 10 is determined for dust catcher according to the utility model embodiment below with reference to Fig. 1-Fig. 8 descriptions.

With reference to shown in Fig. 1-Fig. 3, determine impeller 10 for dust catcher according to the utility model embodiment and can include：Wheel Circle 11 and blade 12.

Specifically, blade 12 can be including multiple, multiple blades 12 can be along the circumferentially distributed of wheel rim 11, each blade 12 extend from inside to outside to the direction at the middle part far from wheel rim 11, and the inner end of each blade 12 can be connected with wheel rim 11.This Outside, flow-guiding structure 13 can be equipped on wheel rim 11, flow-guiding structure 13 can include the first guide face 131 and the second guide face 132, First guide face 131 can be located on the inner peripheral surface of wheel rim 11, the second guide face 132 can extend to two neighboring blade 12 it Between.

In the related art, only determine the blade of impeller and carry out water conservancy diversion to gas, in gas flow, inevitably It is impacted by impeller is determined, influences the flow velocity and flow of gas, determine the less efficient of impeller.

And in the utility model, gas determines leaf by when determining impeller 10, not only blade 12 can carry out gas water conservancy diversion The first guide face 131 and the second guide face 132 of wheel 10 can also carry out water conservancy diversion to gas.Gas can be in the first guide face Enter between blade 12 under 131 guide functions, and the second guide face 132 between blade 12 and two neighboring blade 12 It is flowed under guide functions to the direction at the middle part far from wheel rim 11.The guide functions of flow-guiding structure 13 can be such that gas stream moves more It is smooth, be conducive to improve the efficiency for determining impeller 10.

It should be noted that flow-guiding structure 13 is not limited to include the first guide face 131 and the second guide face 132 simultaneously.Example Such as, in some embodiments of the utility model, flow-guiding structure 13 can only include be located on the inner peripheral surface of wheel rim 11 first Guide face 131.For another example in other embodiments of the utility model, flow-guiding structure 13 can also only include extending to phase The second guide face 132 between adjacent two blades 12.In other words, flow-guiding structure 13 includes be located on the inner peripheral surface of wheel rim 11 the One guide face 131 and extend at least one of second guide face 132 between two neighboring blade 12.This can be realized Flow-guiding structure 13 is within the protection scope of the utility model the guide functions of gas.

In addition, the utility model the quantity of blade 12 is not done it is specifically limited, according to actual conditions needs can flexibly set The quantity of blade 12 is put, for example, in some specific embodiments of the utility model, the quantity for determining the blade 12 of impeller 10 can be with It is 19, determines the more efficient of impeller 10.Certainly, in other specific embodiments of the utility model, the number of blade 12 Amount can also be respectively 17,21 etc..

Flow-guiding structure 13 is included for the impeller 10 of determining of dust catcher according to the utility model embodiment, can not only be passed through Blade 12 carries out water conservancy diversion, can also carry out water conservancy diversion to gas by the flow-guiding structure 13 of setting, water conservancy diversion effect promoting can be more preferable Ground ensures the flowing velocity and circulation of gas, is conducive to improve system effectiveness.

Impeller 10 is determined for dust catcher according to the utility model one embodiment, as shown in Figure 1, the first guide face 131 can axially downwardly be inclined outwardly extension relative to wheel rim 11, thus, it is possible to make air-flow opposite along the first guide face 131 In wheel rim 11 axially downwardly and outward flowing, limit gas flow direction, make enter blade 12 between gas flow more Greatly, it is more efficient.

It should be noted that in the utility model, the range of the first guide face 131 of the inner peripheral surface of wheel rim 11 is not spy Different limitation can be that the first guide face 131 is formed at the lower part of the inner peripheral surface of wheel rim 11, and the range of certain first guide face 131 can With bigger, for example, it may be the entire inner peripheral surface of wheel rim 11 forms the first guide face 131.In other words, the inner peripheral surface of wheel rim 11 At least the first guide face 131 is formed at lower part.

In some embodiments of the utility model, as shown in Figure 1, the first guide face 131 can be annular, annular the One guide face 131 can be used for the area bigger of water conservancy diversion, be further ensured that the percussion smaller for determining impeller 10 and gas, water conservancy diversion Effect is more preferable.

Optionally, in the utility model, the first guide face 131 can prolong relative to the axial direction of wheel rim 11 along straight incline It stretches, can also tilt and extend along camber line, this can reduce the impact to gas, guide functions be played, all in the utility model Protection domain within.

In addition, it as shown in figure 3, is formed in the embodiment of the first guide face 131 in the lower part of the inner peripheral surface of wheel rim 11, wheel rim Fillet surface 133 can be formed at the top of 11 inner peripheral surface, fillet surface 133 relative to wheel rim 11 axially upwards to outer straight line or Person's camber line tilts extension, convenient for determining the connection of impeller 10 and other connection structures.

Some embodiments according to the present utility model, as depicted in figs. 1 and 2, the second guide face 132 can be relative to wheel rim 11 axially along the extending direction of blade 12 from inside to outside tilt extension upwards, thus, it is possible to which increasing gas outflow determines impeller 10 circulation, and gas can be guided to flow up, make gas may exit off determine impeller 10 after smoothly enter with determining impeller 10 connected other components, water conservancy diversion effect are more preferable.

Furthermore, it is necessary to illustrate, the second guide face 132 between two neighboring blade 12 can be whole relative to wheel One that tilts extension or the second guide face 132 upwards axially along the extending direction of blade 12 from inside to outside of circle 11 Split-phase tilts extension upwards for wheel rim 11 axially along the extending direction of blade 12 from inside to outside, such as the specific reality of Fig. 1 and Fig. 2 It applies shown in example, the inner end of the second guide face 132 the prolonging from inside to outside along blade 12 in the axial plane perpendicular to wheel rim 11 The side of stretching upwardly extends, the outer end of the second guide face 132 relative to wheel rim 11 the extending direction axially along blade 12 from inside to outside Extension is tilted upwards, can also realize the guide functions to gas.
