Description
Technical field
The present invention relates to a kind of servicing unit of waste heat boiler, be particularly applied to the mechanical ash removing device that metallurgy and cement industry residual heat boiler for exchanging heat face deashing are used.
Background technology
At present, for realizing recycling of the energy, waste heat boiler has obtained general application.Particularly in industries such as cement, metallurgy, in production process, can produce a large amount of height, middle temperature waste gas, but owing to containing a large amount of dust in waste gas, utilizing waste heat boiler to reclaim in this part of waste heat process, when flue gas passes through residual heat boiler for exchanging heat face, easily on heating surface, adhere to, fouling, cause that exhaust gas temperature raises, affect the heat exchange efficiency of waste heat boiler; Severe one waste heat boiler heating surface is formed wash away, wear and tear, even worn out pipe, cause the production accidents such as boiler stopping production.So must adopt suitable purge mode, to alleviate and to prevent the impact of dust on waste heat boiler, improve the heat exchange efficiency of waste heat boiler, extend the life-span of waste heat boiler.The method of Boiler Convection Heating Surface pipe deashing has the modes such as steam soot blowing, acoustic wave ash ejector deashing, deflagration type shock-wave ash-clearing, mechanical rapping cleaning dust at present, it is large that the fact shows that these several purge modes all can not be effective to ash amount, dust is gently thin, easily produces in the waste heat boiler of the characteristics such as bonding.Also have at present dust cleaning brush assembly is arranged to the ash cleaner for exhaust-heating boiler between heat exchange tube assemblies, as " a kind of mineral hot furnace type waste heat boiler dust cleaning brush assembly " (application number is 201020632772.4) of Chinese patent announcement, it is to the effect that: dust cleaning brush assembly comprises two blocks of supporting plates, steel wire lump and two pressing plates for deashing, between supporting plate and set of heat exchange tubes, leave 5 ~ 20mm gap, supporting plate clamps deashing with steel wire lump, and be placed in the gap between supporting plate and set of heat exchange tubes, supporting plate is the strip supporting plate that upper and lower both sides are all provided with inner groovy, and the quantity of inner groovy is corresponding with quantity and the position of every heat exchanger tube of set of heat exchange tubes with position, supporting plate has locating hole, two are revolved as locating hole fixing by bolt with the pressing plate of supporting plate equal length, supporting plate is clamped and fix deashing steel wire lump.The weak point of above-mentioned dust cleaning brush assembly is: because dust cleaning brush structure is limit, heat-transfer surface can only adopt light-pipe structure, affects heat transfer effect; Dust cleaning brush adopts steel wire lump, easily wearing and tearing, and change inconvenient; This structure is only applicable to mineral hot furnace, and limitation is large.
Summary of the invention
The object of the present invention is to provide a kind of energy consumption low, easy for installation, not easy to wear, maintenance is convenient, and furnace wall is difficult for leaking out, and can thoroughly remove again a kind of ash cleaner for exhaust-heating boiler of stickiness and slagging scorification dust stratification.
The present invention mainly comprises motor, reductor, transmission mechanism, the support of bearing, bearing, leading screw, the axis of guide, slide block, drive link, universal connecting base, brusher deashing mechanism.Wherein, motor is connected with reductor, and this reductor is connected with transmission mechanism one end, and above-mentioned transmission mechanism can be chain and sprocket driving device, can be also rack and pinion drive, can also be shaft coupling transmission device.The above-mentioned transmission mechanism other end is connected with one end of leading screw, and this leading screw can be trapezoidal screw, can be also that rectangle leading screw can also be ball-screw, and the two ends of this leading screw are respectively equipped with bearing, and this bearing is located at respectively on two supports of bearing.On above-mentioned leading screw, be provided with the slide block corresponding with it, one end of this slide block and the drive link parallel with leading screw is connected.Best above-mentioned two bearings support is respectively equipped with two pairs of through holes, and another of its correspondence, to being provided with the axis of guide parallel with leading screw in through hole, is provided with slide block on above-mentioned leading screw and the axis of guide.Above-mentioned drive link is through another set through hole on a transmission mechanism support of bearing far away, end is connected with brusher deashing mechanism, in order to guarantee brusher deashing mechanism traveling comfort, between drive link and brusher deashing mechanism, preferably by universal connecting base, be connected.Above-mentioned brusher deashing mechanism mainly includes: brush fixture, brush, roller and guide rail.The brush fixture being connected with drive link is a framework, this can be placed in the framework in boiler, the two sides of its formation are parallel with boiler heat exchange pipe row, on this framework, being provided with that upper and lower two ends are separately fixed on framework is the brush on end face and bottom surface, and these brushes all with the every two groups of heat exchanger tubes row of boiler between position corresponding, preferably brush quantity is heat exchanger tube row amount n+1 individual (1 < n < 80).Between above-mentioned and every two groups of heat exchanger tubes row, corresponding brush can be one, and they form one group of brush; Preferably arranging corresponding brush with every two groups of heat exchanger tubes is m (the 1 < m < 10) being interrupted, and they form many group brushes, to shorten drive link stroke.Above-mentioned brush can be row brush or twisted wire brush, and preferably the shape of brush bristles part and heat exchanger tube row shape match.Brush fixture bottom is provided with two groups of rollers, and every group of roller is placed on a guide rail, and the two ends of two guide rails are connected with inner casing with boiler draft beam.Preferably before and after every group of roller, establish one group of dust cleaning brush, to prevent causing brusher deashing mechanism stuck in motion process because of guide rail dust stratification.
The course of work of the present invention is: motor via reducer and transmission mechanism drive leading screw to rotate, and slide block is moved reciprocatingly on leading screw, and the drive link being connected with slide block drives brush fixture to move reciprocatingly.Because brush is located at two groups of positions between heat exchanger tube row, so brush just can be by under the dust cleaning on boiler heat exchange pipe row in reciprocating.
The present invention compared with prior art tool has the following advantages:
1, the present invention adopts the mode deashing that brush directly contacts with heat-transfer surface, can thoroughly clean out the dust stratification on heat-transfer surface, because brush is to make with row brush or twisted wire brush, bristle is processed into the shape matching with heat exchanger tube row, contact with tube wall zero distance, there is certain rigidity and resilience, more easily remove the dust stratification of stickiness, slagging scorification, exchange heat pipe row is not wearing and tearing also, prolonged boiler service life.
2, the present invention adopts a rhizoid thick stick to drive a drive link to do linear reciprocating motion, has again the axis of guide to lead, and makes operation more steady.Owing to only having single drive link through furnace wall, reduced the air leak rate of air curtain of boiler, increased the waste heat recovery efficiency of boiler; And simple in structure, easily process and overhaul, lightweight.
3, in brusher deashing mechanism of the present invention, brush fixture adopts tower structure, can change according to boiler heat exchange face flexible in size the quantity of brush.So the present invention is widely used, be applicable to being arranged between the exchanging pipe of boiler by waste row of all size.
4, below brusher device of the present invention, be provided with roller, this device can be rolled in orbit, because frictional force is little, can reduce the energy consumption of drive unit.
