Description
Technical field
The utility model relates to blower fan field, particularly a kind ofly anticorrosionly protects structure with axle head.
Background technique
Blower fan is the mechanical energy that relies on input, improves supply gas the side by side machinery of body of gas pressure.At present, existing blower fan material is carbon steel, and impeller reel material is HT200, and main shaft is 45# steel, and impeller reel and main shaft fix with round nut.In the time that blower fan fed sheet of a media is general air, main shaft contacts with air with round nut, has no effect.But in the time that blower fan fed sheet of a media is corrosive gas, corrosive gas can be degenerated main shaft and round nut surface at leisure, reduce the reliability that main shaft is connected with round nut, and then may occur the phenomenon that impeller reel is loosening, affect the safe handling of blower fan.For this reason, some producers use main shaft and nut instead corrosion-resistant material, but, this on the one hand corrosion-resistant material matter compared with 45# steel, its price, the main shaft of corrosion-resistant material is compared with 45# steel on the other hand, its intensity is low, in the situation that ensureing running ability, certainly will increase its size, cause the increase of cost.
Model utility content
The purpose of this utility model is to provide a kind of anticorrosionly protects structure with axle head, can effectively solve the problem that in prior art, main shaft is corroded.
To achieve these goals, the technical solution of the utility model is achieved in that a kind of anticorrosionly protects structure with axle head, it is characterized in that, comprise,
One fan casing, is formed with a containing space in it, have one and penetrate hole on described fan casing;
One blower fan main shaft, it has a first end and one second end, and described blower fan main shaft first end hole that penetrates through described fan casing from described fan casing extends in the containing space of described fan casing;
One impeller reel, it is positioned at described containing space, and described impeller reel has an impeller hub and an impeller disk, and described impeller disk is arranged on described impeller hub, and described impeller hub is arranged on described blower fan main shaft first end; And,
One protective cap, it is positioned at described containing space, and described protective cap is arranged on described impeller hub, in order to contain and to seal described blower fan main shaft first end.
As a kind of anticorrosion preferred version by axle head protection structure; described blower fan main shaft first end is followed successively by a thread section, a first paragraph and a second segment; described impeller hub is arranged on described first paragraph; by a nut that is sheathed on described thread section, described impeller hub is pressed in described second segment, realize the axial restraint of described impeller hub.
As a kind of anticorrosion preferred version by axle head protection structure, described protective cap is mainly made up of a cap main body and a cap flange, and described cap flange combines with described impeller hub one end face.
As a kind of anticorrosion preferred version by axle head protection structure, described protective cap and described impeller reel are anticorrosion material.
Compared with prior art, advantage of the present utility model: simple in structure, easy for installation; by the design of safety cover; completely corrosive gas and spindle nose are separated, the problem of thoroughly avoiding spindle nose and nut to be degenerated, improves the connection reliability of nut and impeller reel effectively.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
Refer to Fig. 1, shown in figure is a kind of anticorrosionly to protect structure with axle head, is mainly made up of a fan casing 1, a blower fan main shaft 2, an impeller reel 3, a seal arrangement 4 and a protective cap 5.
Wherein, in described fan casing 1, be formed with a containing space 10, on described fan casing 1, have one and penetrate hole 11.
Described blower fan main shaft 2 has a first end (being left end in figure) and one second end, and described blower fan main shaft 2 first ends hole 11 that penetrates through described fan casing 1 from described fan casing 1 extends in the containing space 10 of described fan casing 1.Described blower fan main shaft 2 first ends are followed successively by a thread section 21, a first paragraph 22 and a second segment 23.Described thread section 21 diameters are less than described first paragraph 22 diameters, and described first paragraph 22 diameters are less than described second segment 23 diameters.
Described impeller reel 3 adopts corrosion-resistant material.Described impeller reel 3 is positioned at described containing space 10.Described impeller reel 3 has an impeller hub 31 and an impeller disk 32, and described impeller disk 32 is arranged on described impeller hub 31, and described impeller hub 31 is arranged on the first paragraph 22 of described blower fan main shaft 2.Described impeller hub 31 has along being left end in the axial first end 311(figure of described blower fan main shaft 2) and one second end 312, described impeller hub 31 first ends 311 extend to the junction of described first paragraph 22 and described thread section 21, by a nut 6 that is sheathed on described thread section 21, described impeller hub 31 is pressed in described second segment 23, realize the axial restraint of described impeller hub 31.Described impeller hub 31 second ends 312 penetrate hole 11 to described fan casing 1 extension from described fan casing 1.
It is outer that described seal arrangement 4(is positioned at described fan casing 1) be arranged on described impeller hub 31 second ends 312.Described seal arrangement 4 has a sealing ring pad 41 and a sealing clamp 42, described sealing clamp 42 presses described sealing ring pad 41 in described fan casing 1, what seal by this described fan casing 1 penetrates hole 11, prevents that corrosive gas is from penetrating hole 11 leak into.
Described protective cap 5 adopts corrosion-resistant material.Described protective cap 5 is positioned at described containing space 10.Described protective cap 5 is mainly made up of a cap main body 51 and a cap flange 52, and described cap flange 52 combines by bolt with described impeller hub 31 first end 311 end faces.By described protective cap, described blower fan main shaft 2 first ends and nut 6 are covered completely, separate completely with the corrosive gas in described containing space 10, avoid being degenerated.Because being separates completely, the material of described blower fan main shaft 2 and nut 6 is not subject to the limitation of corrosion-resistant requirement, can adopt common 45# steel, both reduces costs like this, can ensure again structural strength.
The using method of this device and existing blower fan are basic identical.Blower fan main shaft 2 second ends are directly connect to drive motor or connect drive motor by speed reducer, drive blower fan main shaft 2 to rotate by drive motor.In the process of rotating, impeller reel 3 and protective cap 5 are followed rotation simultaneously.
Below only expressed mode of execution of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to utility model patent scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
