The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：

It refer to Fig. 1 to Fig. 2, in embodiment, a kind of two-way dust arrester of flue of automatic collection ash, including chassis 10, set Cylinder 20, cutter revolving part 30, several locating wheels 40, stepper motor 60 and dust ash bucket 70；The locating wheel 40 is fixedly installed Inside the sleeve 20；The cutter revolving part 30 includes several bracing rings 31 and several scraper groups 32 being connected； The cutter revolving part 30 is arranged inside the sleeve 20, and the outside of bracing ring 31 abuts against with the locating wheel 40.It is whole Structure as body use carries out dedusting to the dust in flue, can effectively reach pipeline and be blocked without dust stratification, not, is replaced with machinery It is artificial to improve operating efficiency, realize easy removing large-scale pipeline black dirt.

It refer to Fig. 2, in embodiment, the quantity of the bracing ring 31 is three；The quantity of the scraper group 32 is two； The bracing ring 31 is connected with scraper group 32；Each scraper group 32 includes four doctor units 321；The doctor unit 321 are uniformly arranged on the side of the bracing ring 31 and using 180 ° of symmetrical expression distributions two-by-two.Doctor unit 321 uses staggered Arrangement, staggered doctor unit 321 plays striking off effect to black dirt, have between doctor unit 321 it is at regular intervals, to reach saving Material and the weight for mitigating cutter rotary body, and total frictional force of the cutter rotary body when inner-walls of duct works is reduced, while Ash and dirty more easy-clear can be made.

Further, the doctor unit 321 includes connecting portion 3211 and several spread configurations in the connecting portion Blade 3212 on 3211；The blade 3212 is set in crotch claw-like, the blade on two adjacent doctor units 321 3212 setting directions are conversely to realize two-way dedusting.；The blade 3212 has a certain distance apart from the inwall of sleeve 20, described in definition The distance of blade 3212 and the inwall of sleeve 20 is d, and wherein d scope is 1mm~3mm, it is preferred that d value takes 2mm, adopts The minimum of frictional force can be ensured while dust removal requirement is met with such gap setting；

In addition, it is detachably connected between the doctor unit 321 and the bracing ring 31；Specifically, the support Enclose 31 both sides and be provided with several fixed sockets 311；The both ends of connecting portion 3211 are also equipped with and the phase of fixed socket 311 The inserted sheet of adaptation, structure as overall use can realize fast assembling-disassembling, easy to carry, can be quickly adapted for various differences Occasion.

It refer to Fig. 2, in embodiment, the groove being adapted with the locating wheel 40 be provided with the outside of bracing ring 31 312.Four locating wheels 40 are evenly arranged with each groove 312；The locating wheel 40 is further connected with fixation Seat 50；The fixed seat 50 is achieved a fixed connection by bolt and the sleeve 20.Support wheel is used as using locating wheel 40, played Support and the effect rolled, using the bracing ring 31 for being provided with groove 312, ensure the stability of rotational trajectory.

It refer to Fig. 2, in embodiment, the stepper motor 60 is arranged in chassis 10；Described one end of stepper motor 60 is entered One step is coaxially connected with an active travelling gear 80；One end of bracing ring 31 above the travelling gear is fixedly connected with one Slave drive gear 90 is meshed with realizing with the active travelling gear 80, utilizes determining installed in the inwall surrounding of sleeve 20 Position wheel 40 replaces jackshaft, avoids using jackshaft, so as to mitigate the influence to pipeline interior air-flow, also to save as rotating support shaft Saved many spaces, at the same compared to DC speed-reducing for, this programme selection stepper motor 60, because deashing device torque It is required that it is bigger, and can accelerate deashing speed with stepper motor 60, reduce noise.

Specifically, this deashing device will mainly examine the load-bearing of bracing ring 31 and be connected with the active travelling gear 80 The load-bearing of drive link, in addition the material of blade 3212 we also to meet environmental requirement in flue, according to stepper motor 60 Power and its intrinsic nominal parameter, we can calculate：

According toKnown 60 power of stepper motor=15kw, rotating speed 400r/min, its efficiency eta_w= 95%.

So work tractive force of stepper motor 60Its moment of flexure T_DirectlyF_w×r =35.6 × 20=712Nmm >=650Nmm, so the moment of flexure of stepper motor 60 meets the requirements, its cutter can be driven to rotate.

Length=230mm of other drive link, it is 156N that blade 3212, which can scrape ash disposal and the support reaction of dirt needs,.So by Formula T=F_Branch× l=230 × 156=35880Nmm≤95000Nmm, so the stress in connecting rod sectionSo the stress of drive link meets the requirements, ash disposal can be scraped Dirt.

Fig. 1 is refer to, to solve the problems, such as dust deposit in flue and flue scale removal, the design of pipeline is with certain slope α (α About 1 °~2 °).The bottom of sleeve 20 offers several rectangular through-holes 21；The dust ash bucket 70 is arranged at the rectangle The lower section of through hole 21, specifically, the quantity of the rectangular through-hole 21 is two, respectively positioned at the end and middle part of the sleeve 20, The black dirt on the inside of tube wall can be scraped under the rotation of blade 3212, be allowed by the gradient of sleeve 20 and the flowing of air-flow The black dirt scraped can be moved in dust ash bucket 70, and black dirt is concentrated and further located using dust ash bucket 70 Reason.

It refer to Fig. 1, in embodiment, the material of the chassis 10 is the aluminium section bar using 3030, is machined to cutting Required length, cuboid framework shape is then assembled into, overall structure is simple, and it is firm to consolidate.

In addition, the device further comprises electric-control system, and electric-control system mainly uses arduinomega2560 As Master control chip, the rotation for carrying out cutter with rotating speed by controlling stepper motor 60 to turn to is controlled, secondly also matched somebody with somebody single-chip microcomputer Standby LCD display, the operating rate of current cutter being shown, the function realizes fairly simple, stable performance, meanwhile, stepper motor 60 are controlled by positive and negative rotating controller to realize that cutter carries out scraping ash toward bidirectional rotation, can manually press key control To carry out remote control by Digiplex, inductor is installed in pipeline, can be according to the dust stratification degree detected certainly The rotating speed of dynamic regulation motor, its is simple to operate to be easy to user to operate.

Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model Within the spirit and principle of utility model, any modification, equivalent substitution and improvements done etc., the utility model should be included in Within the scope of protection.
