Abstract
The utility model discloses a kind of one-level movable vane, comprise moving vane, the side of described moving vane is provided with stator blade, described stator blade comprises the end wall of the sidewall of S-shaped setting, the substrate wall of rectangle and arc, described sidewall, substrate wall and end wall are wholely set, and be equipped with frosting above it, described sidewall, substrate wall and end wall are equipped with for the fixed hole fixing with rotating shaft.One-level movable vane of the present utility model, just can be effectively fixed to moving vane in rotating shaft by the setting of sidewall, substrate wall and end wall, in not only simple and fixing process, can not produce bubble at connection part, more firm compared to welding.
Description
Technical field
The utility model relates to a kind of blade, and more particularly, it relates to a kind ofly can install firm one-level movable vane.
Background technique
TRT is the by-product utilizing blast furnace process, and the pressure energy that top gas has and heat energy, made coal gas be done work by turbo-expander, be translated into mechanical energy, then is electric energy by changes mechanical energy.All along with huge energy in whole operation process, the effect of blower fan is exactly transported toward next device by the energy in gas, so the effect of blower fan is very important.And the work conveying gas of blower fan mainly relies on movable vane to carry, so movable vane is very important for whole running.
Existing movable vane Technical comparing is ripe, and type miscellaneous has, and has accomplished reduction resistance, raise the efficiency, simplified apparatus size, but for the mounting technique of movable vane less than position, if movable vane is not installed firmly, on-stream generation disengaging will cause security incident.
The existing mounting type to one-level movable vane for increase by a welded post on movable vane, then by welding manner, one-level movable vane is installed in rotating shaft, but by welding mode can keep away can not exempt from welding position on there is bubble, like this one-level movable vane run process in just there will be install unstable problem.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is that providing a kind of can install firm one-level movable vane.
For achieving the above object, the utility model provides following technological scheme:
A kind of one-level movable vane, comprise moving vane, the side of described moving vane is provided with stator blade, described stator blade comprises the end wall of the sidewall of S-shaped setting, the substrate wall of rectangle and arc, described sidewall, substrate wall and end wall are wholely set, and be equipped with frosting above it, described sidewall, substrate wall and end wall are equipped with for the fixed hole fixing with rotating shaft.
By adopting such scheme, stator blade is used for installing, and moving vane is mainly used for rotation and provides wind-force.The sidewall of the S shape of stator blade and the end wall of arc are all to provide a larger area, making to increase with the frictional force of surface of contact, thus make to install more firm.The frosting that sidewall is arranged also is to further increase the friction with surface of contact, is install firmly to make equally.It is to make moving vane interlock together with stator blade that substrate wall and moving vane are fixedly connected with.Fixed hole on stator blade, effectively can increase by screw the soundness be connected between stator blade with rotating shaft, make the connection between one-level movable vane and rotating shaft more firm, effectively avoid because weld the not firmly problem of the connection between one-level movable vane and rotating shaft causing the inside of the connection part between one-level movable vane and rotating shaft to have bubble to cause.
The utility model is set to further: described fixed hole is provided with 4, and its distribution arrangement is distributed to end wall to sidewall successively by substrate wall, and in straight line.
By adopting such scheme, by fixed hole being arranged to 4 and arranging along straight line, just effectively by screw, stator blade can be fixed in rotating shaft, and a reinforcement effect is carried out to it.
The utility model is set to further: described fixed hole inwall all offers screw thread.
By adopting such scheme, by screw thread, utilizing bolt to be installed by stator blade comparatively expediently, and being also convenient to stator blade to pull down.
The utility model is set to further: the hole wall of described fixed hole is frustoconic shape.
By adopting such scheme, when being installed by stator blade, by the bar installed, the bar of installation, first through the lower end surface of fixed hole, is being worn to upper-end surface.Wearing in the process of upper-end surface, the bar of installation can be out of shape and will withstand fixed hole, namely uses the mode of interference fit firmly to be installed by stator blade.
Accompanying drawing explanation
Fig. 1 is the plan view of the utility model embodiment one-level movable vane;
Fig. 2 is the profile of the utility model embodiment one-level movable vane;
Fig. 3 is the structural representation that the utility model embodiment one-level movable vane is installed on rotating disk.
Description of reference numerals: 1, moving vane; 2, stator blade; 3, sidewall; 4, substrate wall; 5, end wall; 6, fixed hole.
Embodiment
Be described in further details with reference to accompanying drawing 1 to 3 couple of the utility model one-level movable vane embodiment.
One-level movable vane of the present utility model, can make the movable vane of installation more firm, and the position that adjustable movable vane is installed, be described as follows.
With reference to accompanying drawing 1, when installing stator blade 2, fixed hole 6 is set to frustoconic shape, in the process worn, realizes interference fit from above, installs firmly, but is not easy to dismounting.
With reference to accompanying drawing 1, utilizing the screw thread of fixed hole 6 inside adding the bolt coincide with it, realizing being threaded between fixed hole 6 with the rotating shaft that will be connected, comparatively firmly, and dismantled and assembled.
With reference to accompanying drawing 3, assuming that one-level movable vane is arranged on rotating disk, rotating disk needs to arrange the groove with stator blade 2 shape size adaptation, stator blade 2 is placed in a groove, be fixed by fixed hole 6 again, certainly also need to arrange the hole consistent with fixed hole 6 on rotating disk, realize both combinations.The sidewall 3 of S shape, the end wall 5 of arc, with frosting (with reference to accompanying drawing 2), be all the surface of contact in order to increase between stator blade 2 and rotating disk, realize larger frictional force, just effectively can increase the connectivity robustness between stator blade 2 and rotating disk, prevent and have bubble to make one-level movable vane with the connection part inside between rotating disk because weld the one-level movable vane that causes and be connected unstable problem between turning, by the axis hole on rotating disk, axle is inserted, realizes the rotation of rotating disk.The rotation of rotating disk drives the rotation of stator blade 2.The substrate wall 4 of stator blade 2 is connected with the connecting wall of moving vane 1, and moving vane 1 starts dial rotation.The concave wall of moving vane 1, convex wall and arcwall, in the rotary course of moving vane 1, can reduce the resistance between fluid.In TRT, fluid mainly refers to gas.Thus realize whole complete process.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
