Description
Technical field
The utility model relates to a kind of flyash ceramisite sintered kiln.
Background technology
Flyash is the pressed powder that the thermal power plant flue is discharged, and a large amount of flyash that the thermal power plant produces have taken a large amount of soils, river course, mountain valley and coastal beach, serious contaminated environment when stacking.Greatly develop at present in country under the situation of recycling economy, the comprehensive Utilization Ways of flyash gets up, and concerning containing the higher flyash inferior of charcoal, producing sintering ceramsite with flyash is exactly a fabulous approach.As far back as earlier 1950s, Britain utilizes flyash to produce haydite the earliest in the world; China in 1964 in Tianjin silicate product factory and Lanzhou built up two production lines of sintering flyash ceramic grain, reached the production climax the seventies and eighties, the back is because of multiple reasons such as twice power consumption, environmental protection, the economic benefit state that seizes up.Started the climax of total utilization of PCA again up to the nineties, but slower to the speed of sintering flyash ceramic grain exploitation, never very big breakthrough.The higher flyash inferior of utilization carbon content is produced lytag, is the key subjects of total utilization of PCA in the current recycling economy.
Lytag be a kind of be primary raw material with flyash, the artificial lightweight aggregate of producing through technical process such as metering, conveying, balling-up, sintering, fragmentation, screenings.Lytag is divided into spheroidal and rubble shape, and indexs such as its cylindrical compress strength, water absorption rate, stability, coefficient of softing, frost resistance all meet the requirement of relevant national standard.Lytag is widely used in as light-weight aggregate and makes light aggregate concrete and materials for wall.
Traditional flyash ceramisite sintered equipment mainly contains equipment such as sintering machine, rotary kiln, mechanical vertical kiln.The sintering machine investment is huge, and cost is too high; Though the investment of rotary kiln is littler than sintering machine, to invest still greatlyyer, cost is also too high; The mechanical vertical kiln investment is less, the discharging difficulty, and sintering quality is inhomogeneous.The unit that has uses simple and easy shaft kiln, adopts static, batch (-type) sintering process, sintering made from full fly ash haydite; With the firewood igniting, utilize the charcoal sintering flyash ceramic grain of the remnants in the flyash, burn haydite without coal; Small investment, simple to operate, product quality meets the relevant national standard requirement.But its fatal shortcoming is discontinuous, and baked one kiln is once fiery with firewood point, and igniting not only brings cost to increase, and produces flue dust, contaminated environment.The utility model is exactly through a kind of flyash ceramisite sintered kiln of design, through once lighting a fire with firewood, utilizes the carbon content burning of flyash self, thereby realizes continuity, static sintering.Equipment is simple, and small investment is easy to operate, and operating cost is low, good product quality, energy-conservation environmental protection again.
The utility model content
The purpose of the utility model is: overcome the problem and shortage that above-mentioned lytag production equipment exists, provide that a kind of equipment is simple, small investment, easy to operate, operating cost is low, the flyash ceramisite sintered kiln of good product quality, energy-conservation environmental protection again.The technical scheme of the utility model is achieved in that a kind of flyash ceramisite sintered kiln, comprising: carry the conveyer 12 of lytag raw material ball 1, the stacking platform 2 of lytag raw material ball 1, pan feeding wicket 3, outer wall 4; Inwall 5, ring-shaped sintered chamber 6, ventilation shaft 7, air-introduced machine 8, cylindrical air inducing chamber 20; Discharging opening 18, annular U type steel tank 9, at the bottom of the kiln 17, outer wall support column 19, operating platform 15; Kiln body support column 16 leaks glassware 10, carries the conveyer 11 of the lytag 13 that sinters, the movable kiln grate 14 that can extract out or insert; Desulfurizing dust-collector 21, scraper plate 22, annular steel ring 23, driving chain 24; Ring-shaped guide rail 25, gear 26, motor 27 is arranged in the square aperture 28 and the chimney 29 of annular U type steel tank 9.
A kind of flyash ceramisite sintered kiln of the utility model, lytag raw material ball 1 is deposited on the platform 2 through carrying 12; First during sintering; Bottom tiling one deck firewood of the ring-shaped sintered chamber 6 that need constitute at the inwall 5 that outer wall of being built by laying bricks or stones by refractory brick 4 and refractory brick are built by laying bricks or stones is lighted firewood from discharging opening 18, starts air-introduced machine 8 simultaneously; Be provided with desulfurizing dust-collector 21 at air-introduced machine 8 front ends; It links to each other with air-introduced machine 8 with ventilation shaft 7, is discharged by chimney 29 through the gas behind the desulfurization and dedusting, reaches environmental requirement; After firewood burns to a certain degree, open pan feeding wicket 3, lytag raw material ball 1 passes through pan feeding wicket 3, drops on to be positioned on the firewood that is burning annular flyash ceramisite sintered chamber 6; Take the production technology of smoldering, burn one deck and add one deck lytag raw material ball 1, carry out so repeatedly, lytag raw material ball 1 passes through technical process such as preheating, sintering, cooling successively; When the height of lytag salband has surpassed the height of discharging opening 18, insertion activity kiln grate 14; Starter motor 27 drives scraper plate 22 annular steel rings 23 is housed, rotation in annular U type steel tank 9; The lytag 13 that sinters is drawn out through discharging opening 18; Fall in the annular U type steel tank 9, in scraper plate 22 is fallen Lou glassware 10, be transported to the finished product stockyard through conveyer 11 at last; Till lytag 13 has gone out, movable kiln grate 14 to be extracted out, cooling back lytag is fallen on the platform of discharging opening 18; When the salband of lytag has surpassed the height of discharging opening 18, insert kiln grate 14 again, carry out discharging, go down so repeatedly, realized static, continuous sintering.
