Abstract
The utility model discloses a kind of stationary vane assembly easy to clean, comprise blade and for blade being fixed to the fixed mechanism on TRT, described fixed mechanism comprises the fixed strip being bent into " Z " shape, described fixed strip one end and blade removably connect, the other end offers through hole, is equipped with the stationary axle for being fixed on TRT in described through hole.Stationary vane assembly easy to clean of the present utility model, by the setting of fixed strip, just can effectively blade be fixed on TRT, and blade and fixed strip removably connect, just effectively when blade is dirty, blade can be disassembled from TRT, facilitate the cleaning course to blade greatly.
Description
Technical field
The utility model relates to a kind of stationary vane assembly, and more particularly, it relates to a kind of stationary vane assembly easy to clean.
Background technique
TRT specifically refers to blast-furnace top gas recovery turbine generator, is the pressure energy and heat energy that utilize the by-product top gas of blast furnace process to have, utilizes coal gas to do work to turbo-expander, be translated into mechanical energy, then be electric energy by changes mechanical energy.In whole production process, TRT there will be vibration, main cause is the power resources of generator is blast furnace gas, analyze with practical conditions, because its medium is coal gas, in coal gas inside containing a large amount of dusts, so after long usage, because stator blade is actionless, a large amount of dusts will be accumulated in the above, make the thickness of stator blade and surface configuration all can produce change, thus impact at coal gas in the process of stator blade, the flow direction that just there will be air-flow changes, whole TRT is finally made to produce vibration in the process run, and existing stationary vane assembly is wholely set a fixed block to fix blade and TRT on blade, and the annexation of fixed block and TRT is all by having welded, like this after stator blade is dirty, cannot disassemble from TRT, with regard to being difficult to, the blade of stator blade is cleaned.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is the stationary vane assembly easy to clean providing a kind of easy to clean.
For achieving the above object, the utility model provides following technological scheme:
A kind of stationary vane assembly easy to clean, comprise blade and for blade being fixed to the fixed mechanism on TRT, described fixed mechanism comprises the fixed strip being bent into " Z " shape, described fixed strip one end and blade removably connect, the other end offers through hole, is equipped with the stationary axle for being fixed on TRT in described through hole.
By adopting such scheme, just can effectively blade be fixed on TRT by the setting of fixed strip, simultaneously by setting that fixed strip one end and blade removably connect, when blade is dirty, just blade can be disassembled in fixed strip, clean one by one, compared to existing leaf cleaning mode, facilitate many beyond doubt, that also cleans is more clean simultaneously.
The utility model is set to further: described blade is provided with fixing column with the side towards fixed strip, and described fixed strip offers attachment hole, and described fixing column dorsad blade one end wears in fixed strip, and offers attachment hole equally.
By adopting such scheme, by all offering attachment hole on fixed strip and fixing column, just fixing column can be connected on fixed strip by bolt, fixed strip is fixed on the internal chamber wall of steam turbine, when dismounting blade, only need the bolt unscrewed on fixing column, convenience very, effectively facilitate the cleaning process of blade.
The utility model is set to further: described fixing column is arranged with lining, and described lining is arranged with sleeve, and the side of described sleeve is provided with parallel screw and parallel nut.
By adopting such scheme, by the setting with parallel nut of lining, sleeve and parallel screw, wherein parallel nut here and sleeve are coaxially arranged, parallel screw is arranged on parallel nut, like this while stator blade, with parallel nut, blade can also be fixed on steam turbine internal chamber wall by parallel screw, prevent the vibration of blade further.
In the utility model embodiment, fixed strip is connected one end and offers U-shaped hole with fixing column, one end of fixing column is arranged in U-shaped hole, and the hole wall of two of U-shaped hole straight flanges offers attachment hole, communicate with the attachment hole on fixing column, in addition also on the position of its end, set out the same attachment hole at two straight flanges, this attachment hole is below interconnected.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model stationary vane assembly embodiment easy to clean;
Fig. 2 is the blade structure schematic diagram of the utility model stationary vane assembly embodiment easy to clean.
Description of reference numerals: 1, blade; 2, fixed strip; 3, stationary axle; 4, fixing column; 5, attachment hole; 6, lining; 7, sleeve; 71, parallel screw; 72, parallel nut.
Embodiment
Be described in further details with reference to accompanying drawing 1 pair of the utility model stationary vane assembly embodiment easy to clean.
A kind of stationary vane assembly easy to clean, comprise blade 1 and for blade 1 being fixed to the fixed mechanism on TRT, described fixed mechanism comprises the fixed strip 2 being bent into " Z " shape, described fixed strip 2 one end and blade 1 removably connect, the other end offers through hole, is equipped with the stationary axle 3 for being fixed on TRT in described through hole.
By adopting technique scheme, when stator blade 1, first by stationary axle 3, fixed strip 2 is fixed on (employing welding manner) on the internal chamber wall of steam turbine, and then blade 1 is fixed on fixed strip 2, after blade 1 is dirty, only need blade 1 to disassemble from fixed strip 2, very simple and convenient, the easy greatly cleaning process of blade 1, makes the cleaning of blade 1 seem more simple.
Below the connection procedure between above-mentioned mentioned blade 1 and fixed strip 2 and principle are described in further detail.
With reference to shown in Fig. 1, when blade 1 is installed on fixed strip 2 by needs time, first the fixing column 4 on blade 1 is worn in fixed strip 2, and its side offers attachment hole 5 equally, attachment hole 5 on fixing column 4 is connected with the attachment hole 5 on fixed strip 2, take a screw afterwards through above-mentioned attachment hole 5, to screw on again afterwards nut, this completes fixing blade 1, then a screw is adopted again, through the attachment hole 5 near its end on U-shaped hole hole wall on fixed strip 2, also adopt a nut screwing clamping simultaneously, U-shaped like this hole will produce the effect of a clamping to fixing column 4, increase the soundness of the connection between fixing column 4 and fixed strip 2, the parallel screw 71 be arranged on sleeve 7 can also be adopted to be secured on the internal chamber wall of steam turbine simultaneously and (tapped hole can be offered on steam turbine internal chamber wall, parallel screw 71 screwin), the soundness that further increase blade 1 is connected with steam turbine internal chamber wall.
In sum, the setting that removably connected with blade 1 by fixed strip 2 and fixed strip 2, just effectively when blade 1 is dirty, can be disassembled blade 1 and has cleaned in steam turbine, greatly the cleaning process of blade 1 easily.
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.
