Abstract
The invention relates to the technical field of boiler deslagging, in particular to a comb-shaped air-cooled spiral deslagging device of a cycle burning grate boiler. The invention aims to solve the technical problems that the cycle burning grate boiler has the disadvantages that: the larger particles of slag in the cycle burning grate boiler cannot be discharged automatically; the labour intensity is increased by manual removal; the removal effect is bad; and the working efficiency of the boiler is lowered or the boiler stops when a certain amount of the slag is accumulated. In order to solvethe technical problems, the invention adopts a technical scheme of providing the comb-shaped air-cooled spiral deslagging device which consists of a hollow shaft with two blocked ends, a plurality ofhollow teeth and a stuffing box provided with a cold air inlet pipe, wherein the hollow teeth are vertical to the hollow shaft, are welded with the spirally distributed through holes on the cylindrical surface of the hollow shaft respectively in a matching mode and are arranged spirally around the cylindrical surface at one end on the hollow shaft; the stuffing box is matched with the cold air inlet through holes on the cylindrical surface at the other end of the hollow shaft on the hollow shaft. When in use, the comb-shaped air-cooled spiral deslagging device passes through a dust removing opening and the hollow shaft and the cold air inlet pipe on the stuffing box are connected with a speed reducer and a draught fan respectively.
Description
Technical field
The present invention relates to boiler grate furnace slag technical field, particularly relate to a kind of comb-shaped air-cooled spiral deslagging device of the burn-out grate boiler that circulates.
Background technology
The patent No. is a kind of circulation burn-out grate of 022598820, the grate furnace fire grate that provides coal in stove, to circulate and to burn, it is short that this fire grate can solve coal holdup time in stove that reciprocal grate and traveling-grate stoker and all mechanization grate firing fire grates exist in the coal-fired fire grate of existing mechanization, can not fully burn, burn problem.But, circulation burn-out grate boiler is when providing coal to circulate in stove to burn, also bring new problem to boiler slag removal, can be except that slag by air vent is discharged on gap between fire grate segment and the fire grate segment than granule, the slag of larger particles can not be discharged automatically.When needing to remove, can only extract with crooked chisel or cleek at furnace grate support sidewall ash disposal mouth place by manpower.Its shortcoming is not only to increase labour intensity, removes poor effect, can not in time discharge the fire coal that will continue along with not burning as the slag of larger particles and circulate in stove, and the accumulation some causes boiler work decrease in efficiency or shutdown the most at last.
Summary of the invention
The technical problem to be solved in the present invention is that the slag of larger particles can not be discharged automatically in the circulation burn-out grate boiler, and artificial the removing increases labour intensity, removes poor effect, and untimely removing accumulation some causes the deficiency of boiler work decrease in efficiency or shutdown.
For solving the problems of the technologies described above, the technical solution used in the present invention is for providing a kind of comb-shaped air-cooled spiral deslagging device, it is by the hollow shaft of a two ends faces end head plugging, some hollow teeth are formed with the stuffing-box that has the cold wind access tube, one newel post's surface helix of described hollow shaft is distributed with through hole, described hollow tooth is vertical with described hollow shaft and cooperate solid welding with described spiral distribution through hole respectively, described hollow tooth around newel post's face of described hollow shaft in the shape of a spiral shape arrange, the other end cylinder of described hollow shaft has cold wind to feed the hole, and described stuffing-box feeds the hole with described cold wind and cooperates on described hollow shaft.
The present invention compared with the prior art, because when the hollow shaft of comb-shaped air-cooled spiral deslagging device drives rotation at power-equipment, be fixed on hollow tooth that the shape in the shape of a spiral on the hollow shaft arranges along with rotation, after the larger particles slag that runs to ash disposal mouth corresponding section on the fire grate is caught by hollow tooth, becoming spiral to extrude under the power effect at hollow tooth-shape discharges from the ash disposal mouth automatically, its beneficial effect is that the slag of larger particles in the circulation burn-out grate boiler can be discharged automatically, reduce labor intensity, be unlikely to produce the bulky grain slag and in boiler, accumulate, guaranteed that boiler normally moves because of deslagging inconvenience.In addition, hollow shaft, hollow toothing can be realized air cooling, have guaranteed that comb-shaped air-cooled spiral deslagging device is in furnace high-temperature environment operate as normal.
