Description
Technical field
Flue deashing dust removal field is the utility model is related to, is filled more particularly, to a kind of deashing of horizontal placement flue
Put.
Background technology
To prevent that dust deposits in flue in flue gas, it is 10-15m/s typically to require flue gas flow rate, but many pipelines,
Particularly large-scale pipeline is generally unable to reach so high flue gas flow rate, causes dust deposit in flue phenomenon unavoidably.
For the fouling phenomenon in some small-sized horizontal pipes, have patent CN2169495 propose using mainly by ash-scraper,
The deashing device that steel wire rope, changed course pulley and driving drum are formed carries out deashing to small-sized long pipeline.The device, which uses, is less than pipe
The ash-scraper of road diameter carries out scraping ash to pipeline, and centre, which understands the ash of some, can not scrape totally.Using steel wire rope as scraping ash
The supporting arrangement of device, can not if pipeline is longer, and because the gravity of steel wire rope and ash-scraper in itself, easily causes to be bent downwardly
Ensure the validity of its supporting, gently then ash-removal effect is had an impact, it is heavy then ash-scraper can be caused, which to be stuck in inside, to be used.With
The closure that steel wire rope is used cooperatively, being installed in the pipeline that had certain requirements to ventilation flow rate can cause extraction flow to decline,
Influence the normal use of machine.The direction of ash-scraper is altered course using two reverse wheels, causes external structure to increase, is commutated
Two is needed to coordinate.
Existing large-scale flue, deashing method is more original, poorly efficient after dust stratification, can only send work people after power generation operation
Member enters manual cleaning.
To sum up, the shortcomings that prior art：
1st, the supporting member using steel wire rope as ash-scraper inside pipeline, due to itself Action of Gravity Field and rope class
The characteristic itself being easily deformed, easily cause support to be failed, influence device normal operation.
2nd, closure is used in pipeline, unless changing existing pipe shape, the gas in pipe is had a strong impact on after otherwise adding
Body circulates.
3rd, a reverse wheel is respectively used at pipeline external both ends, commutation can not be completed in a place, and device commutation is more multiple
It is miscellaneous.
4th, in order to avoid there is the stuck phenomenon in pipeline of ash-scraper, ash-scraper diameter is more less than pipe diameter, shadow
Ring cleaning efficiency.
5th, large-scale pipeline can not use the apparatus for ash of scraping of small-sized flue, and existing purge mode is to shut down deashing, takes pole
It is long, plant efficiency is had a certain impact.
Utility model content
The purpose of this utility model is exactly a kind of horizontal positioned in order to be provided the defects of overcoming above-mentioned prior art to exist
The deashing device of formula flue, have the advantages that Stability Analysis of Structures, cleaning efficiency are high, for the deashing of sizes pipeline, be particularly

Large-scale ventilation shaft.Bottom surface is played a supporting role in the guide rail supporting frame of arc surfaced to scraping ring main body, prevents guide rail from deforming.
2nd, using intermediate hollow and the circular scraper plate with hollow out, so as to reduce the occupation of land of pipe portion central robot structure
Space, the normal circulation without influenceing gas.
3rd, by setting scraping blade, scraping blade is close to flue inner wall so that and scrape ring diameter and be close with pipe diameter, and scraping blade
Right-angle triangle is advantageous to scraping ring and come and gone back and forth, realize no dead angle, it is comprehensive scrape ash, further improve it and scrape grey effect
Rate.
4th, annulus scraping ring material of main part is aluminium alloy, lighter weight, but hardness is big, and squeegee material is Teflon, heat resistance
Good, elasticity is big, and frictional force is small, and wear resistance is good, is not easy because slight shift is stuck in flue, and ensure that the ash scraped is pushed into
Small ash bucket.
5th, compared with existing purge mode, operating efficiency is improved, deashing can be carried out while normal work, and
Remove clean.
6th, compared with existing purge mode, suitable for the deashing of sizes pipeline, particularly transverse horizontal putting type
The deashing of large-scale pipeline, the setting of flue-dust retainer are easy to focus on the dust scraped.
7th, the device motor has been installed in outside flue, can with during electrical fault do not have to dismounting flue.
8th, simple in construction, flue connects for flange, is easy to take apart and changes scraping blade and maintenance, easily can according to circumstances change
Scraping blade, makes the operating efficiency of the application will not be reduced with the time.
9th, the length of sliding block is 2 ~ 3 times of thickness of scraping ring, by increasing the length of sliding block, to ensure scraping ring on guide rail
Stable sliding.
