Description
Technical field
The utility model relates to closed conduit field, particularly relates to a kind of fluid force conveying elbow.
Background technique
Fluid force is carried, and can utilize the energy of the fluid such as current or air-flow, along fluid flow direction conveying granular material in closed conduit, be a kind of embody rule of fluidization technology; The structure of fluid force feedway is simple, easy to operate, can do level, the conveying of vertical or true dip direction, in course of conveying, also can carry out physical operations or some chemical operation such as the heating of material, cooling, drying and air current classifying simultaneously; Fluid force delivery line comprises straight tube direction pipeline and elbow, can realize material turning in the duct by described elbow; When material is carried in the pipeline of straight tube direction, the reference angle that material particles and tube wall bump against is very little, can not cause serious wearing and tearing; But when material enters into elbow, due to the change of moving direction, by the effect of centrifugal force and inertia force, particle clashes into elbow internal wall in the mode of jet, through repeatedly colliding friction, the wearing and tearing of elbow, perforation inefficacy can be caused, thus decrease the length of service of elbow, add amount of maintenance, reduce manufacturing efficiency, add cost, material even can be caused to leak and befouling environment.
Model utility content
For solving the problems of the technologies described above, the utility model provide a kind of structure simple, be convenient to manufacture, safe and reliable, its reasonably structure effectively can extend the working life of elbow in Pneumatic conveying pipeline, the life-span can improve tens times compared with common elbow; The reliability of fluid delivery system can be improved, reduce the fluid force conveying elbow of elbow spare part expense and maintenance expenses.
A kind of fluid force conveying elbow of the present utility model, comprises the eccentric elbow main body of reducing, inlet tube and outer pipe, and described inlet tube and described outer pipe are connected with the two-port of described reducing bias elbow main body respectively; The equal diameters of described inlet tube and described outer pipe, the diameter of two-port of the eccentric elbow main body of described reducing and the equal diameters of described inlet tube and described outer pipe, the diameter of all the other cavitys of the eccentric elbow main body of described reducing is all greater than the diameter of described inlet tube and described outer pipe; The bending radius of the outer side wall of the eccentric elbow main body of described reducing is greater than the bending radius of the madial wall of the eccentric elbow main body of described reducing.
As preferably, the eccentric elbow main body of described reducing is hemispherical cavity shape.
As preferably, the eccentric elbow main body of described reducing and described inlet tube and described outer pipe one-body molded.
Compared with prior art the beneficial effects of the utility model are: a kind of fluid force conveying elbow, its structure is simple, be convenient to manufacture, safe and reliable, it reasonably constructs the working life that effectively can extend elbow in Pneumatic conveying pipeline, and the life-span can improve tens times compared with common elbow; The reliability of fluid delivery system can be improved, reduce elbow spare part expense and maintenance expenses.
Accompanying drawing explanation
Fig. 1 is a kind of fluid force conveying elbow sectional structure schematic diagram of the present utility model.
Wherein, 1, inlet tube; 2, elbow main body; 2-1, elbow main body outer side wall; 2-2, elbow main body madial wall; 3, outer pipe.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of dedicated elbow of fluid force conveying, comprise inlet tube 1, elbow main body 2 and outer pipe 3, described elbow main body 2 is the eccentric elbow of reducing of hemisphere type cavity, except the equal diameters of elbow main body 2 two-port diameter and inlet tube and outer pipe, the diameter of all the other cavitys is all greater than the diameter of inlet tube and outer pipe; The described center of circle of elbow main body madial wall 2-2 and the center of circle of outer side wall 2-1 are not same point, and the bending radius of outer side wall 2-1 is greater than the bending radius of madial wall 2-2.When fluid stream and the medium be transferred are when arriving the connecting part of inlet tube 1 and elbow main body 2 in fluid force course of conveying, a part can enter into outer pipe 3 by elbow main body 2 under the effect of inertia force and fluid stream, and the outer side wall 2-1 that a part can clash into elbow produces with it friction and forms buildup dead band herein.The connecting part sectional area of inlet tube 3 and elbow main body 2 increases suddenly rate of flow of fluid is reduced, and effectively can reduce fed sheet of a media to the shock of elbow main body 2 outer side wall 2-1 and friction; In elbow main body, the effect of wearing layer can be played again in the 2 buildup dead bands formed, and makes conveying medium only wash away buildup in dead band, thus plays the effect of the elbow main body that adequately protects.
Compared with prior art the beneficial effects of the utility model are: a kind of fluid force conveying elbow, its structure is simple, be convenient to manufacture, safe and reliable, it reasonably constructs the working life that effectively can extend elbow in Pneumatic conveying pipeline, and the life-span can improve tens times compared with common elbow; The reliability of fluid delivery system can be improved, reduce elbow spare part expense and maintenance expenses.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
