Abstract
The utility model discloses an oxidized pellet sintering device which is a mechanized energy-saving device for producing oxidized pellets in steel industry. The utility model can replace the production of oxidized pellet in a flat blowing type. The oxidized pellet sintering device is composed of three semi-spherical furnace bodies with the same size, a fume exhaust tube provided with a control valve, an air supply tube, and a hot air circulating tube. The utility model has the advantages of high yield rate, low labour intensity, energy and fuel saving without polluting environment, short production periodicity, low cost, and small land occupation.
Description
The acid pellet calciner belongs to a kind of mechanize energy saver of Iron And Steel Industry metallurgical production acid pellet.
Since the eighties; the high quality pelletizing has become one of vital measure of blast furnace ironmaking raw material Increasing Production and Energy Saving; promoted the fast development of iron ore concentrate pelletizing, it is with level land oxygen blast pellet stoving oven that China produces by indigenous method, and all there is detrimentally affect the quality and the environment protection aspect of pelletizing.Chinese invention patent 85104051 is a kind of methods of on the portable furnace coral agglomerate or agglomerated materials being heat-treated, though the production process of gas and heat is improved in system, energy consumption is low, effectively utilized waste heat, but, oversize to the whole process of second cooling zone from drying zone, floor space is big, the apparatus structure complexity.
The purpose of this utility model provides a kind of energy saver of small oxygen pellet production mechanization, and he can replace the production of level land oxygen blast pellet, changes the backward situation of the small-sized pellet formation of China.
The utility model acid pellet calciner is a kind of acid pellet calciner of being made up of stoving oven, air blast fume exhaust system, hot air circulating system, it is characterized in that stoving oven is a semisphere, in fire grate is arranged, under pick airduct, petticoat pipe on the bell joins with the smoke evacuation house steward, the hot air circulation pipe is connected between smoke exhaust pipe and the blast tube, and three stoves are connected into integrative-structure.Air-supply smoke evacuation and hot air circulation all with valve control, can realize a stove roasting, a stove preheating, a stove refrigeration cycle operation.
The characteristics of the utility model acid pellet calciner are the yield rate height, and labour intensity is little, and is free from environmental pollution, save the energy and right material, and with short production cycle, equipment is simple, and is with low cost, and floor space is little.
Embodiment
The concrete structure of the utility model acid pellet calciner embodiment is example with the accompanying drawing, make the semisphere stoving oven (1) that accompanying drawing is showed with 12 millimeters steel plate, its bulb radius is 0.6 meter, suitable for reading is horizontal edge, being welded into the cylinder-like part horizontal edge with steel plate with same specification docks, fix with snap ring, 1.2 meters of cylinder-like part diameters, horizontal edge suitable for reading and petticoat pipe (12) edge coupling dock, and petticoat pipe (12) is funnel shaped, on thermoelectricity occasionally temperature instrumentation hole (9) is arranged, 1.2 meters of big mouthful diameters, 0.3 meter of osculum diameter and smoke exhaust pipe (5), tornado dust collector (6), chimney (8) is communicated with.The fixing Reinforced hook used of furnace lining of welding on stoving oven (1) inwall is beaten with the alumina cement refractory aggregate and to be served as a contrast 80 mm thick, reinforcing bar bar shaped grate (13) is arranged bottom the stoving oven, covers on air outlet (14) and locates.This device has three same stoving ovens and combines.Smoke exhaust pipe of each stove (5) and smoke evacuation house steward (7) are joined, the lower end links to each other with blast tube (3), gas blower (2), connect with hot air circulation pipe (15) between smoke exhaust pipe (5) and the blast tube (3), on smoke exhaust pipe (5), blast tube (3) and hot air circulation pipe (15), by-pass valve control (4) is installed all, control the trend of air-supply, smoke evacuation and hot blast with valve, thereby can realize a stove roasting, one stove preheating, the processing requirement of one stove refrigeration cycle operation, wheel (16) is equipped with in three stove lower ends, is located on the track (10).The acid pellet that is beneficial to sinter in the stoving oven is pushed into the stock ground along track (10) and is drawn off by shedding mechanism.
