The utility model discloses can carry out high pressure conveying, can not lead to the fact when carrying simultaneously and carry remaining of article, long -time transport also need not be cleared up, has improved transport efficiency, the workman's that also lightens the amount of labour.
Description
Technical field
The utility model relates to the parts on conveyor screw, particularly relates to a kind of Shaftless spiral blade.
Background technology
Shaftless screw conveyor is widely used in food, metallurgy, chemical industry, building, mine, hydraulic engineering, engineering of water treatment etc.Due to Shaftless spiral blade non-stop layer axle, relative to there being axle helicallobe, its intensity is much lower, and service life is also shorter.
As shown in Figure 1, Authorization Notice No. is CN201882572U, and authorized announcement date is that the Chinese utility model patent on June 9th, 2011 discloses a kind of strengthened type shaftless helical blade, comprises helicallobe 1, the outer circumference surface of described helicallobe 1 has stiffening band 2.The thickness of described stiffening band is greater than the thickness of described helicallobe.Two planes up and down of stiffening band are equal to the distance of the central cross-section of helicallobe.This novel Shaftless spiral blade improves on Shaftless spiral blade basis, contrasts original Shaftless spiral blade, has anti-folding, antitorque, the anti-significantly mechanical characteristic such as flexible; Strengthened type shaftless helical blade described in the utility model, under bad working environments, can ensure the stable of feed status by actv., and this characteristic is that same specification shaftless screw is incomparable; Strengthened type shaftless helical blade described in the utility model is owing to broadening the thickness of ectoloph, effectively raise the area of contact with liner plate, after the operation break-in of short-term, abrasion factor is compared shaftless screw and is reduced by 20 ~ 30%, can increase the service life by actv..
Above-mentioned patent is strengthened bringing the intensity improving helicallobe by increasing; but due to adding of stiffening band; make between the helicallobe of Shaftless spiral blade and stiffening band, to define a groove 3; when carrying the materials such as such as food; food is likely piled up in this groove 3; add the conveying intensity of Shaftless spiral blade; Shaftless spiral blade is caused normally to carry; long-time conveying also needs workman to shut down the food debris of clearing up on Shaftless spiral blade; reduce transport efficiency, too increase the labor content of workman.Helicallobe, after working long hours, can produce heat, improves the temperature of helicallobe, and helicallobe is softened, and intensity reduces, and cannot adapt to the conveying environment that pressure is large.
Utility model content
The defect strengthening bringing increase Shaftless spiral blade intensity to bring is added in order to overcome existing Shaftless spiral blade, the utility model provides a kind of Shaftless spiral blade, this Shaftless spiral blade adds its intensity, high pressure transmission can be carried out, the residual of conveying article can not be caused when conveying simultaneously, long-time conveying also need not be cleared up, and improves transport efficiency, the labor content of the workman also alleviated.
The utility model for solving the problems of the technologies described above adopted technical scheme is:
A kind of Shaftless spiral blade, comprises helicallobe, it is characterized in that: the outward flange thickness of described helicallobe is less than inward flange thickness, and the two sides being transitioned into inward flange from outward flange is inclined-plane.
The ratio of described outward flange thickness and inward flange thickness is 1:2 ~ 2.5, and the angle being transitioned into one of them face of inward flange and the inward flange of helicallobe from outward flange is 84 °, and the angle of another face and inward flange is 86 °.
Described outward flange and inward flange are provided with groove, and groove extends along the direction of helicallobe.
Compared with prior art, the utility model has the following advantages:
1, the utility model comprises helicallobe, and the outward flange thickness of described helicallobe is less than inward flange thickness, and the two sides being transitioned into inward flange from outward flange is inclined-plane.The outward flange thickness of helicallobe of the present utility model is less than inward flange thickness, and the thickness like this from outward flange to inward flange is thickening gradually, and the center of pressure that such design is mainly born when carrying based on shaftless conveying blade is maximum, the reason that outward flange is minimum.This ensures that there the requirement of strength meeting helicallobe with minimum material, and the two sides being transitioned into helicallobe inward flange from helicallobe outward flange due to the utility model is chamfered transition, make two sides can bear larger pressure, and can not monolateral holding capacity excessive and cause helicallobe to damage.By such design, the strength that the utility model is transmitted is large, can carry out high pressure transport, and blade is not yielding, improves the life-span used.
2, the ratio of the utility model outward flange thickness and inward flange thickness is 1:2 ~ 2.5, is 84 ° from the angle in one of them face and inward flange that outward flange is transitioned into inward flange, and the angle of another face and inward flange is 86 °.By such parameter request, also a saving raw MAT'L while fully ensure that the intensity of helicallobe, reduce manufacturing cost.Such angle design is also the requirement of strength in order to helicallobe.
3, the utility model outward flange and inward flange are provided with groove, and groove extends along the direction of helicallobe.The groove arranged has fan heat effect, and when conveying, helicallobe rotates, and will produce wind, cooling spiral blade, avoid helicallobe to be subject to thermal softening at groove, and intensity reduces.
