Abstract
The utility model discloses a blower impeller belongs to the fan equipment field, and it is higher especially to relate to a wear resistance, and can effectively improve blower impeller and fan equipment's life's blower impeller, including shroud, hub disk, wheel hub and blade, the blade has the polylith, and polylith blade spaced circumference distributes between shroud and hub disk, the central point that wheel hub detachable installed at the hub disk puts, is provided with one deck wear resistant material layer on the windward side of every blade to wear resistant material layer's surface has wear -resisting protrudingly. The utility model discloses a set up wear resistant material layer to and set up wear -resisting protruding, the wear resistance of improvement blade that can be great, and then improve blower impeller and a whole set of fan equipment's life. Simultaneously, through installing wheel hub detachable on the hub disk, make things convenient for more and change the blade.
Description
Technical field
This utility model relates to Fan Equipment field, particularly relates to a kind of draught fan impeller.
Background technology
Draught fan impeller is the important composition parts in blower fan, and in practical work process, the blade within draught fan impeller is often worn, particularly with the environment containing a large amount of solid particles in air, for instance the Fan Equipment used under cement dust environment.Due to existing draught fan impeller, generally do not consider this special environment so that the draught fan impeller used under such circumstances is easily subject to huge abrasion, the service life of serious sound equipment blower fan and draught fan impeller.
Utility model content
This utility model solves the technical problem that and is to provide the draught fan impeller that a kind of anti-wear performance is higher, can be effectively improved the service life of draught fan impeller and Fan Equipment.
This utility model solves the technical scheme is that draught fan impeller of its technical problem, including shroud, hub disk, wheel hub and blade, described blade has polylith, polylith spacing with blades circumferentially distributed between shroud and hub disk, described wheel hub is detachably arranged in the center of hub disk, the windward side of every piece of blade is provided with one layer of wear-resistant material layer, and the surface of wear-resistant material layer has wear-resisting projection.
Further: described wear-resisting projection is spaced semicolumn strip projection.
Further: described wear-resisting projection is vertical with hub disk.
Further: being provided with sheet head protrusion on the wear-resistant material layer corresponding with the edge, inlet air place of blade, the height of described head protrusion is highly consistent with wear-resisting projection, and its width is more than the width of wear-resisting projection.
Further: the height of described wear-resisting projection is 3-5mm, its width is 10mm, and the spacing between adjacent two wear-resisting projections is 25mm.
Further: told wear-resistant material layer and blade are welded to connect.
The beneficial effects of the utility model are: by arranging wear-resistant material layer, and arrange wear-resisting projection, can be greatly improved the anti-wear performance of blade, and then improve draught fan impeller and the service life of a whole set of Fan Equipment.Meanwhile, by wheel hub is detachably arranged on hub disk, convenient blade is replaced.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further illustrated.
Shown in as shown in Figure 1 to Figure 4, draught fan impeller described in the utility model, including shroud 1, hub disk 2, wheel hub 3 and blade 4, described blade 4 has polylith, polylith blade 4 interval circumferentially distributed between shroud 1 and hub disk, described wheel hub 3 is detachably arranged in the center of hub disk 2, it is characterised in that: on the windward side of every piece of blade 4, it is provided with one layer of wear-resistant material layer 5, and the surface of wear-resistant material layer 5 has wear-resisting projection 6.
Wherein the effect of wear-resistant material layer 5 and wear-resisting projection 6 is the anti-wear performance in order to improve blade 4, it is generally the case that the anti-wear performance of wear-resistant material layer 5 and wear-resisting projection 6 should be above the anti-wear performance of blade 4.
Concrete, as shown in Figure 3 and Figure 4, wear-resisting projection 6 can be spaced semicolumn strip projection.And can wear-resisting projection 6 be vertically arranged relative to hub disk 2 further, so that wear-resisting projection 6 and air flow direction are approximately perpendicular direction.
Additionally, consider that the abrasion at blade 4 inlet air place is typically more serious, therefore can being provided with sheet head protrusion 7 on the wear-resistant material layer 5 corresponding with the edge, inlet air place of blade 4, the height of described head protrusion 7 is highly consistent with wear-resisting projection 6, and its width is more than the width of wear-resisting projection 6.Sheet head protrusion 7 is actual can be regarded as the relatively common broader wear-resisting projection of wear-resisting projection 6 of width, and simply the trend of its setting is the edge, inlet air place along blade 4, in order to strengthen the wear-resisting intensity at this place.
Under normal circumstances, the height of wear-resisting projection 6 may be configured as 3-5mm, and its width may be configured as about 10mm, and the spacing between adjacent two wear-resisting projections 6 may be configured as about 25mm.
It addition, the annexation between wear-resistant material layer 5 and blade 4, the mode as screw connects or directly welds can be adopted.When adopting welding manner, should guarantee that the intensity of weld seam is not less than the intensity of mother metal as far as possible.
