Abstract
Provided is a wind type draught fan blade structure. A blade is made of low alloy steel plates, an upper steel plate and a lower steel plate are welded to form an empty cavity, and a plurality of reinforcing steel plates are arranged inside the empty cavity of the blade along the inner radial direction in spot welded mode. Meanwhile, wear-resisting alloys are arranged on a windward surface of the blade in bead welded mode, and the empty cavity of the blade is filled with light foam materials. The wind type draught fan blade structure is simple in technology, convenient to process, and capable of effectively extending a wear through time of the wing type draught fan blade and prolonging the service life of the wing type draught fan blade.
Description
Technical field
The utility model relates to Fan Equipment, is specially a kind of wing formula fan blade structure.
Background technique
In a lot of commercial Application, in the actual fabrication of blower fan was used, wing formula blade was used by a large amount of; Be mainly used in the raising fan efficiency; Cut down the consumption of energy, and wing formula blade blower fan can be used for medium containing dust, and (dust loading is under 0.1～100g) the work condition environment, thereby applicable surface is wider.
Existing wing formula blade all is to utilize upper and lower two block plates welding to form cavity, and only can several stiffening plates of spot welding in the cavity, makes wing formula blade in use; Its mouth that facings the wind is worn out easily, and dust gets into blade interior easily in the medium, forms dust stratification; And dust stratification moves easily; And original balance of destruction draught fan impeller makes blower fan produce vibration, dislocation, and influences the normal device operation.
The model utility content
The technical problem that the utility model solved is to provide a kind of wing formula fan blade structure, in order to prolong the wing formula worn out time of blade; Solve the problem of the worn out back of wing formula blade dust stratification, destruction impeller balance.
The technical problem that the utility model solved adopts following technological scheme to realize:
A kind of wing formula fan blade structure utilizes Low Alloy Steel Plate to make blade, and the welding of upper and lower two block plates forms cavity, and at blade cavity inside several strengthening steel slabs of spot welding radially, simultaneously, the build-up wear-resistant alloy in the windward side of blade; And blade cavity inside filling lightweight foam material.
In the utility model, during the light filling foam material,, lightweight foam material is filled with the blade cavity from tapping from the perforate of blade lee face, treat after filler sclerosis or the curing hole to be shut.
Beneficial effect: the utility model has solved the problem of worn out easily, the worn out back of wing formula blade dust stratification destruction of balance well, has prolonged the working life of draught fan impeller effectively.
Description of drawings
Fig. 1 is the generalized section of the utility model preferred embodiment.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to the preferred embodiment of a kind of wing formula fan blade structure of Fig. 1, in the present embodiment, utilize the Q345-B steel plate to make blade 1, four blocks of Q345-B steel plates of blade 1 inner spot welding are as strengthening steel slab 2.
As abrasion resistance alloy 3, blade 1 mouthful built-up welding thickness down with the wind is 6mm at blade 1 windward side built-up welding VAUTID-100, and all the other position built-up welding thickness are 3mm.
In the present embodiment; The internal cavities of selecting common polyurethane foam material to fill in the blade 1 as filler 4, from the lee face perforate of blade 1, each cavity is opened a hole; Filler 4 is filled with the blade cavity, and filler solidified after 24 hours shuts the perforate hole.
More than show and described the advantage of basic principle, major character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
Claims (1)
1. a wing formula fan blade structure is characterized in that, utilizes Low Alloy Steel Plate to make blade, and the welding of upper and lower two block plates forms cavity, and at blade cavity inside several strengthening steel slabs of spot welding radially, simultaneously, the build-up wear-resistant alloy in the windward side of blade; Simultaneously, also be filled with lightweight foam material at the blade cavity inside.
