Abstract
The utility model provides a kind of compound sandwich fan balde structure, includes base plate, lateral ribs, longitudinal reinforced rib, outer layer covering, foam-filled, interface end；It is described transverse direction ribs, longitudinal reinforced rib be set to base plate on, lateral ribs, longitudinal reinforced rib cross one another be arranged to it is latticed；The foam-filled seamless filled grid formed into lateral ribs, longitudinal reinforced rib；The outer layer covering is set to lateral ribs, longitudinal reinforced rib, foam-filled outer；The interface end is set on base plate；The fan balde structure is blade root close at interface end, is blade tip at separate interface end；The structure is higher than homogeneous structure rigidity, intensity, deforms small, weight saving.
Description
Technical field
The utility model is related to technical field of industrial dust removal more particularly to a kind of compound sandwich fan balde structures.
Background technology
The a large amount of dusts generated when factory work need strong large-scale fan to be dusted operation, otherwise can influence to make
Industry efficiency and operation achievement.Certain industrial dedusting is high with large-scale rotation speed of the fan, and longtime running is big in temperature difference humidity, water mist, salt fog,
In the complexity rugged environment such as mould, mist of oil and sand and dust, common blade construction and material are difficult to meet requirement.For
This, industry needs the large-size fan blade of a kind of high-performance, high stability.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of compound sandwich fan blade is provided
Structure, the structure are higher than homogeneous structure rigidity, intensity, deform small, weight saving.
To achieve the above object, the technical solution adopted in the utility model is：A kind of compound concrete-cored fan balde structure, packet
Base plate, lateral ribs, longitudinal reinforced rib, outer layer covering, foam-filled, interface end are included；The transverse direction ribs, longitudinal direction
Ribs be set to base plate on, lateral ribs, longitudinal reinforced rib cross one another be arranged to it is latticed；It is described foam-filled seamless
It is filled into lateral ribs, the grid that longitudinal reinforced rib is formed；The outer layer covering be set to lateral ribs, longitudinal reinforced rib,
It is foam-filled outer；The interface end is set on base plate；The fan balde structure is blade root close at interface end, far from interface
It is blade tip at end.
Preferably, being equally distributed on base plate at the transverse direction ribs blade root to blade tip.
Preferably, the longitudinal reinforced rib is equally distributed on base plate.
The utility model has the beneficial effects that：The structure is higher than homogeneous structure rigidity, intensity, deforms small, weight saving.
Description of the drawings
Attached drawing described herein is to be used to provide a further understanding of the present invention, and constitutes one of the application
Point, but do not constitute the restriction to the utility model.
Fig. 1 is blade vertical section structure schematic diagram, and Fig. 2 is leaf cross-section schematic diagram.
Wherein：1 is basic plate, and 2 be lateral ribs, and 3 be longitudinal reinforced rib, and 4 be outer layer covering, 5 be it is foam-filled, 6
For interface end.
Specific implementation mode
In conjunction with attached drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of compound sandwich fan balde structure, which includes base plate 1, laterally adds
Strong rib 2, longitudinal reinforced rib 3, outer layer covering 4, foam-filled 5, interface end 6；The transverse direction ribs 2, longitudinal reinforced rib 3 are set to
On base plate 1, lateral ribs 2, longitudinal reinforced rib 3 cross one another be arranged to it is latticed；Described foam-filled 5 it is seamless filled into
The grid that lateral ribs 2, longitudinal reinforced rib 3 are formed；The outer layer covering 4 is set to lateral ribs 2, longitudinal reinforced rib 3, bubble
Outside foam filling 5；The interface end 6 is set on base plate 1；The fan balde structure is blade root close at interface end 6, separate to connect
It is blade tip at mouth end 6.
In specific implementation, it is equally distributed on base plate 1 at transverse direction 2 blade root to blade tip of ribs.
In specific implementation, the longitudinal reinforced rib 3 is equally distributed on base plate 1.
