Description
The present invention is a kind of calcination of cement clinker novel vertical kiln.
Existing machine shaft kiln when being used for burning clinker of cement, is mixed in proportion raw material and coal dust usually, after the balling-up of balling-up equipment, enters distribution device, through scraper-trough conveyer, be sprinkled in the kiln, after hot gas flow heats, carries out pre-thermolysis, at kiln body calcining zone mature calcined material.Grog through dumping device and drawing mechanism, is delivered to clinker warehouse by handling equipment by the cooling zone of kiln body.
Go into kiln to burning till before the grog from raw material ball, material not only will pass through preheating, decomposition, calcining, cooling four-stage in the kiln, and require material to supply with competent air in calcination process, so blower fan is constantly blown in kiln by the blast inlet of a kiln base cone shape leakage both sides; On the kiln hood of Yao Ding top, establish two chimneys simultaneously, scavenge.
This forming machine shaft kiln of forming with several parts such as mechanical transmission, cloth, discharging and air supplying and exhausting system.Because the various reasons on the design structure causes transmission efficiency low, kiln room and basic stress complexity, the kiln section ventilates uneven, bad, it is serious to leak out, and chemical combustion is incomplete, and thermo-efficiency is low, easily ties bulk, dust pollution and material fly to lose serious, and power consumption is big, and be many with material, be difficult to stablize good quality and high output.
The objective of the invention is to propose a kind of simplified construction, materials are economized, cost is low, energy consumption is little, and clean cigarette gathers dust, burns soon, cold, quick-release soon, guarantee the novel vertical kiln of good quality and high output.
The present invention with the hydraulic driving machine shaft kiln is being the hydraulic pressure swing, back and forth rotation, twin-tub work, drive unit is directly supported by kiln body seat ring, kiln body seat ring is combed with tower by the ball bearing circle and is linked to each other, oscillating cylinder acts directly on the ball bearing circle that links to each other with the tower comb, therefore changed for example force-bearing situation of vertical shaft driving machine shaft kiln of traditional machine shaft kiln, thereby reduced requirement to basis and kiln room, and discharge system principal part-Ta combs not eccentric, cone shape, the vertical eye of wind of tool, the tower tooth, central air hose, can integral demounting maintenance and establish on the basis of center column a kind of novel vertical kiln of proposition at the kiln body.
Novel vertical kiln hydraulic pressure swing of the present invention, back and forth rotation is adopted anti-dust, is saved lubricated air-cooled, positive seal; Kiln body seat ring is combed to link to each other with tower by the circle of ball bearing up and down that interspaces in advance special maintenance circle is housed between ball, can bolster to or radial force, make supporting structure simple, tower as the discharge system principal part is combed, the vertical eye of wind of concentrated branch in the middle part of tower is combed arranged, whole circle crushing teeth, and level is stretched out certain-length is made of gabarit five triangular ramps and narrow and long rectangular tower tooth on tower comb cone-shaped body, tower is combed not only reduce reduction resistant force, the fragmentation of acceleration grog, press to kiln wall waved plate and E Kou after simultaneously grog being stirred fragmentation, force to rely on no longer merely the grog self-weight blanking; Kiln body cooling zone is a tube type heat exchanger, double shell, and inside and outside cylindrical shell constitutes a cavity, and spiral aviation baffle is housed in it, and the 3rd auxilliary wind, enters in the kiln by adjustable air inlet device also by tube type heat exchanger top.Because the tube type heat exchanger internal-external temperature difference is big, the heat exchanger effectiveness height can not only be strengthened the grog cooling, also can improve the main air wind-warm syndrome simultaneously; Cylinder at kiln top top suspension inner ventilation, directly stretch into the cooling zone expansion section s, the cylinder core barrel is made with high temperature steel, the annular building block that the cylinder outer rim is inlay heat-resistant and wear-resistant material, middle filling aluminum silicate fiber adapts to loose stock column, strengthens apoplexy and grog cooling from structure and size; Neutral single chimney, its structure bottom is the pellet preheating chamber, is followed successively by cleaning apparatus, dust chamber, the chimney of mechanical exhaust, the anti-cone of cover top cap on the chimney; The pellet preheating chamber is equipped with inside and outside rib toroidal helical preheater, makes pellet long distance and time be arranged from flue gas, on chimney barrel, the spiral leaf, absorb used heat by various ways, make pellet be half-dried or dried state and have higher greenhouse and go into kiln, allow the combustion heat fully be used for decomposing and calcining.The dried simultaneously or relative wet feed ball of half-dried pellet has bigger porosity and less viscosity factor, and ventilation resistance is reduced, and airflow circulation is quickened, thereby can improve calcinating speed, reduces the pellet blow-up rate, cuts down the consumption of energy; Annular dust chamber and cleaning apparatus are established in neutral single chimney middle part, and it makes band cloud of dust gas enter high speed rotating dedusting impeller by the taper thrust-augmenting nozzle, the cleaning apparatus of the dust board that leads again.Because centrifugal and inert effect, dust separates at dust chamber with flue gas, delivers to default address (storing or use) through e Foerderanlage, so a large amount of materials are recovered for re-use in the flue gas, not only reduces cost but also improve environment.
