Mobile cleaning mechanism 40 employs mechanical arm 43 and realizes cleaning item 44 to connect the structure of cleaning item 44 and slide bar 42 Linear motion, while by imitate hairbrush bristle shape design the outer layer of cleaning item 44, while this soft from silicon rubber Material, will not produce unnecessary wear-out failure in scale removal process to walling of flue.Simultaneously bristle in motion process due to resistance The vibration that power is produced, also has better effect to the cleaning of dust stratification.

Used simultaneously in view of needing to meet in flue gas, timing belt 33 is from curved tooth timing belt 33, materials'use silicon rubber. Silicon rubber temperature in use is between -50 DEG C~250 DEG C, and highest bearing temperature is much larger than flue environment temperature, while silicon rubber is gathered around There is good corrosion resistance.Compared to such as flat rubber belting, the V band of other types timing belt 33, curved tooth timing belt 33 does not need too high Clamp force requirement, in the absence of phenomenons such as skiddings, while possessing larger torque.Due to timing belt 33 and timing belt 33 during use During wheel engagement, inner air can be extruded from the both sides of race with tooth, cigarette ash therein is taken away simultaneously when air is squeezed away, So as to reach the effect for avoiding dust stratification, available for more severe dust atmosphere.In other performances, curved tooth timing belt 33 possesses good Good wearability, without lubrication.

It refer in Fig. 2, embodiment, the injection tube 50 includes air inlet 51 and injection tube main body 52；The air inlet 51 are set through the wall of flue tube 10；Circular groove is provided with the inwall of flue tube 10 so that the injection tube main body 52 fixation is put Put；Several gas outlets are provided with the sparge pipe main body；The quantity of the injection tube 50 is two and the injection tube main body 52 are close to the outside of cleaning item 44 respectively is provided for being blown the dust on cleaning item 44.

Specifically, controlling compressed air to enter injection tube 50 by PLC control system, pass through going out for being reserved in injection tube 50 Gas port blowing pressurized air reaches the effect for removing the dust stratification adhered in the cleaning process of cleaning item 44.Simultaneously because cleaning item 44 exists Stop in horizontal direction, compressed air can be sprayed towards both sides, and the dust stratification of stack base blow raising operation, is allowed to be easier Flue is taken out of by wind-force.Soot build-up is also avoided in cleaning arm extreme position simultaneously.The injection tube 50 is lighter using weight Aluminum alloy materials.

It refer in Fig. 1, embodiment, the inwall of the flue tube 10 at the driving wheel 31 and the driven pulley 32 enters one Step is each provided with an infrared sensor 80 to control the mechanical arm 43 to realize iterative motion；Use such setting can be with Effectively realize braking of the motor 21 when moving to extreme position to realize the continuous reciprocating motion of mechanical arm 43.

It refer in Fig. 1 and Fig. 3, embodiment, two be further provided with the base 70 and is located at the screw mandrel 63 The optical sensor 90 at two ends and a position sensor 100 for being located at the middle part of screw mandrel 63；It is additionally provided with the base 70 One alarm lamp；Aluminium section bar is additionally provided with the base 70 to be used to fixing and supporting the ash bucket automatic loading and unloading mechanism 60.

Further, the quantity of the ash bucket 65 be two and be respectively arranged at the either end of screw mandrel 63 and it is described enter The lower section of grey-way 61；The ash bucket 65 includes ash bucket main body 651, ash bucket fixed plate 652 and sliding block 653；The ash bucket fixed plate 652 For fixing the ash bucket main body 651；The sliding block 653 is mutually fixedly connected with the ash bucket fixed plate 652 and can drive ash bucket Main body 651 is moved on the screw mandrel 63；Pressure sensor is provided with the ash bucket main body 651.

Specifically, offering neck in the ash bucket fixed plate 652, fixed while both sides set turnover buckle to realize Effect；The ash bucket main body 651 is put into neck, buckle upset in two ends is sticked into ash bucket main body 651, it is ensured that ash bucket 65 can To be fixed in mechanism, the free degree of ash bucket 65 is limited, it is necessary to need to only exert oneself to break into two with one's hands buckle when dismantling, ash bucket 65 can be smooth Dust stratification in cleaning ash bucket 65 is separated from mechanism.

Refer in Fig. 1 and Fig. 3, embodiment, the grey part 62 of gear include dust block board 621 and with the phase of dust block board 621 The cylinder 622 of connection；It is described enter the side of grey-way 61 on be provided with the rectangular channel being adapted with the dust block board 621；The cylinder 622 Can promote the dust block board 621 through the rectangular channel with realize prevent dust continue by it is described enter grey-way 61 fall into the ash bucket In 65；Coordinate the pressure sensor in ash bucket main body 651 simultaneously using such structure to detect service condition to control gear Hawk 621 is pushed into rectangular channel temporarily to prevent dust from going successively to ash bucket main body 651 to realize lower section ash bucket main body 651 more Change.

To sum up, dust stratification weight in ash bucket main body 651 is measured by pressure sensor, when dust stratification weight in ash bucket 65 When reaching rated value, alarm lamp is flashed and PLC control system control cylinder 622 is released, and dust blocking lump prevents dust stratification from continuing to fall into ash Struggle against main body 651, and then spindle motor rotates control has expired the removal ash port of ash bucket main body 651, is controlled by two optical sensors 90 Motor braking processed determines the position of ash bucket main body 651, while determining the rotating of motor by the sensor signal difference of acquisition. When ash bucket 65 reaches specified location, determine whether ash bucket 65 reaches ash port by the position sensor 100 at the middle part of screw mandrel 63, If it is cylinder 622 is withdrawn, if otherwise alarm lamp persistently flash prompting operating personnel check.Using such control mode not Only it is capable of the carrying situation of accurate control ash bucket 65, while coordinating by pneumatic means, it is to avoid when changing ash bucket 65 at flue In open state, apparatus for automatic change it also avoid carrying out artificially changing ash bucket 65, improve operating efficiency.
