Description
Technical field
The invention belongs to a kind of boiler soot-blowing device, be specially adapted to purge dust stratification on the boiler heating surface depth direction and the dust stratification on a certain cross section of heating surface, the rake formula soot blower of the waist that can not collapse, torsional deformation flexible a kind of rail mounted freely.
Background technology
At present, the boiler that is used for all trades and professions, in the flue of especially large-scale ultra-large type boiler the heating surface of arranging surface can long-pending last layer black dirt, increase thermal resistance, influenced the endothermic effect of heating surface widely, when dust stratification is serious, causes the flue resistance increase or flue is stopped up, influence normal operation of boiler and safe operation; In order to address this problem, generally can be on each heating surface of boiler or the various forms of soot blowers of arranged around purge these dusts.In recent years, domestic factory also produces the soot blower that some cleaning boilers are used, grow telescopic soot blower as common a kind of in market, the transmission device that it is made up of gear-worm and wormwheel-displacement gear-walking gear and tooth bar with driven by motor drives ash gun and moves, also ash gun is rotated simultaneously with a conical gear pair, the very complicated manufacturing cost again of its structure height, and powerless to dust stratification on the boiler heating surface depth direction and the dust stratification on the cross section; Have also on the market that a kind of to harrow the expansion link that the formula soot blower stretches in the stove be cantilever, be subjected to high temperature and produce distortion, the waist, stuck that is out of shape, collapses, and cisco unity malfunction.
Summary of the invention
The present invention is intended to the shortcoming and defect part that exists in above-mentioned technology, and provide not only reasonable in design, simple in structure, compact, both be convenient to blow ash, improve cleaning efficiency, do not produce distortion again, make nozzle harrow grey car motion steadily freely, and have handling safety, use a kind of very easily rake formula soot blower.
Purpose of the present invention is to adopt following technical scheme to realize: comprise the motor, decelerator, the spiral nozzle rake formula ash-blowing vehicle that are loaded on the base, be characterised in that: its structure is by stopping rotating mechanism, leading screw, nut casing, location wheels, movable breather pipe, upper and lower track, forming from tensioning apparatus, be connected with leading screw by the driven by motor decelerator, leading screw and nut casing engagement, and make nut casing drive activity breather pipe reciprocating, on the nut casing outer circumference surface, be provided with and stop rotating mechanism; Corresponding with the dust stratification position of boiler internal heating surface, be built-in with spiral nozzle rake formula ash-blowing vehicle at stove, or install in the body of heater above spiral nozzle rake formula ash-blowing vehicle and get on the right track, suspension gear in the installing spiral nozzle rake formula ash-blowing vehicle that gets on the right track, or at several rollers of spiral nozzle rake formula ash-blowing vehicle bottom installing, its roller is placed on the lower railway, and stretch out outside the body of heater at the two ends of described upper and lower track, installs respectively from tensioning apparatus on the upper and lower track termination outside body of heater; Movable breather pipe is connected with spiral nozzle rake formula ash-blowing vehicle in boiler, on the activity ventilation pipeline section outside the body of heater location wheels is set.
The described suspension gear that gets on the right track is made up of hanging wheel, lifting rope, hanger, at the end face installing hanging wheel that gets on the right track, and an end of suit lifting rope on the hanging wheel, the other end system of lifting rope is connected on the hanger of spiral nozzle rake formula ash-blowing vehicle.
Described upper and lower track, or make by rigid material, or make by flexible material; Its cross section of upper and lower track of rigid material system is circular, oval, square or I-shaped; The upper and lower track of flexible material system, its described roller, corresponding with the shape of selected track cross-section, design its structure and shape.
The described rotating mechanism that stops is made up of catch, gear wheel, is provided with the catch of two levels on the outer circumference surface of nut casing, and the angular distance of two catch is 180 °, and is corresponding with the position of two catch, two gear wheels of installing on base; When the motor-driven leading screw rotated, two horizontal catch on its nut casing outer circumference surface were subjected to stopping of gear wheel, and nut casing can not be rotated.
Described from tensioning apparatus, form suit packing ring, spring, packing ring, nut in regular turn on each track end that stretches by spring, packing ring, nut; When producing length dimension when the track temperature influence and changing, the effect of just reliable spring force makes track be in tensioning state all the time, and nozzle harrow the motion in orbit of grey car can be steadily freely.
Described spiral nozzle is harrowed grey car, by longitudinal tubule (L tubule), transverse tube, spiral nozzle, four-way union, tee pipe coupling, roller are formed, longitudinal tubule (L tubule) is made up of several short tubes, connects the tee pipe coupling except that longitudinal tubule (L tubule) is terminal, all connects four-way union between all the other each short tubes, and the transverse tube that connection parallels on each pipe joint, distributing bottom each transverse tube connects several spiral nozzles, corresponding with two rail top face positions, installs the roller that can do relative motion in orbit respectively in first, last transverse tube bottom.
Because the transmission device among the present invention is a stationary fixing formula structure, stable performance, easy-to-operate adopts worm screw nut transmission, and relying on instead, just changeing of nut to drive spiral nozzle, to harrow grey car reciprocating in orbit, comes dust stratification is cleaned; In order further to improve ash-removal effect, adopt the electric magnetic coupling device to control the rotation of nut, harrow grey car and do periodic intermittent movement, make nozzle harrow grey car can carry out the long period to the thicker place of indivedual dust stratifications the ash that blows thereby drive nozzle, both ash-removal effect was good, improved cleaning efficiency again.Combine the above technical measures of being taked, realize purpose of the present invention.
Compared with prior art, the present invention is not only reasonable in design, and is simple in structure, compact, both has been convenient to blow ash, improves cleaning efficiency, do not produce distortion again, makes nozzle harrow grey car motion steadily freely, and has handling safety, uses advantages such as very convenient.
