Currently, spodumene roasting technique mainly uses three-level whirlwind cylinder pre-heating, rotary kiln, grate-cooler combined application, Or two kinds of rotary kiln, grate-cooler combined application process flows.Three-level whirlwind cylinder pre-heating system, spodumene raw material are revolved from the first order The feeding of air duct feed inlet is collected, through feeder pipe, kiln tail smoke-box after the preheating of three-level cyclone cylinder through third level cyclone cylinder Blanking tongue feeding rotary kiln is calcined;The technology is high to material particles Particle size requirements, and there are low separation efficiencies, heat exchange efficiency Low, the defects of voltage loss is big.Another technique be spodumene raw material be fed directly into rotary kiln dried, preheated, turn Type roasting, the technology there are low output, efficiency of heating- utilization is low, system heat consumption is high the defects of.
Utility model content
Purpose: in order to overcome the deficiencies in the prior art, the utility model provides a kind of applied to spodumene roasting The novel pre-heater system of technique.
Technical solution: in order to solve the above technical problems, the technical solution adopted by the utility model is:
A kind of novel pre-heater system applied to spodumene roasting technique, including cyclone cylinder, inclined-plane fluid bed furnace;It is described Cyclone cylinder includes cyclone and airlock;The inclined-plane fluid bed furnace includes furnace body and inclined-plane fluidized bed, and the furnace body is vertical Formula furnace body, the inclined-plane fluidized bed include two layers of inclined-plane sliding bed being distributed up and down, are upper layer inclined-plane sliding bed and lower layer respectively Inclined-plane slides bed, and every layer of inclined-plane sliding bed is provided with air valve and material-pulling device, and the material-pulling device setting is slided on inclined-plane Bed upper end, air valve setting slide bed lower end on inclined-plane;Air inlet is arranged in inclined-plane fluid bed furnace lower end, connects kiln tail cigarette Gas outlet is arranged in room, inclined-plane fluid bed furnace upper end, connects cyclone cylinder.
Preferably, the airlock includes the second air valve and feeder pipe, the feeder pipe be connected to the second air valve and Inclined-plane fluid bed furnace.
Preferably, the feeder pipe is connected to the connecting interface of inclined-plane fluid bed furnace with lower layer inclined-plane sliding bed feeding inlet.
Preferably, the material-pulling device includes the hydraulic cylinder of stick pusher and control stick pusher stretching motion.
Preferably, the inboard wall of furnace body of the air valve and inclined-plane fluid bed furnace that are arranged on the inclined-plane sliding bed is connected by arched girder It connects, the arched girder is formed using fire resisting brick masonry.
Preferably, the upper end of the inclined-plane fluid bed furnace sets feed inlet, and the feed inlet connects dispersion device;The inclined-plane stream The lower end for changing pool furnace sets out material mouth, and the discharge port connects rotary kiln.
The utility model has the advantages that novel pre-heater system provided by the utility model, have occupied area is few, inner structural members are few, The advantages that equipment is simple, preheating heat is high-efficient.The high-temp waste gas that the pre-heating system is generated using dry-process rotory kiln calcining is to original Material is dried, is preheated, to reduce the thermic load of rotary kiln and improve the utilization efficiency of waste heat.Inclined-plane fluid bed furnace uses two Sliding bed in layer inclined-plane is as heat exchange bed, and for material in transverse shifting on inclined-plane bed, hot fume is upward through material from material bottom Layer, forms cross-flow heat exchange, and heat exchange efficiency is higher than fair current;Cavity is interior for gas-solid countercurrent heat exchange, heat exchange efficiency up and down for inclined-plane bed Higher than fair current;Enter the spodumene material temperature of rotary kiln up to 300 DEG C or more after preheater drying preheating;Preheater Cyclone cylinder uses newest double isolation technics, and dust separation efficiency is greater than 96%, and resistance is lower than the first of three-level whirlwind cylinder pre-heating Grade cyclone cylinder, effectively reduces hot dust outer circulation, improves preheater hot recovery efficiency, while reducing subsequent dust pelletizing system load.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is further described with reference to the accompanying drawing.
As shown in Figure 1, a kind of novel pre-heater system applied to spodumene roasting technique, including cyclone cylinder 2, inclined-plane stream Change pool furnace 1.
The inclined-plane fluid bed furnace 1 includes furnace body 11 and inclined-plane fluidized bed, and the furnace body 11 is vertical furnace, the inclined-plane Fluidized bed includes two layers of inclined-plane sliding bed being distributed up and down, is that upper layer inclined-plane sliding bed 12 and lower layer inclined-plane slide bed 13 respectively, Every layer of inclined-plane sliding bed is provided with air valve and material-pulling device, and the material-pulling device setting slides bed upper end on inclined-plane, locks wind Valve setting slides bed lower end on inclined-plane.The air valve and material-pulling device can be set multiple.
