Description

The Magnesium Carbonate Light 41-45 calcining is the device of activated magnesia
Technical field
The utility model relates to a kind of Magnesium Carbonate Light 41-45 calcining and is the device of activated magnesia.
Background technology
The calcining of traditional lightweight magnesiumcarbonate mainly divides two kinds for the equipment of light magnesium oxide: the box-type furnace that (1) refractory brick is built into, a grid dress Magnesium Carbonate Light 41-45 material, a grid makes a fire, be staggered, the a plurality of such material grid and the grid that makes a fire, by the refractory brick radiation, material is given in thermal conduction, need to burn tens hours, could calcine; (2) stainless steel converter, converter is oval tubular, and the converter bottom is with coal gas or burn the coal indirect heating, and long cylinder 3 drives continuously by motor 2 and rotates, one end adds Magnesium Carbonate Light 41-45, another brings out light magnesium oxide, and as Fig. 1, the temperature of charge that comes out has more than 800 ℃, put into a lot of metal buckets 1, naturally cooling is about 24 hours, just can go the next process screening, packing.
More than two kinds of device temperatures cannot control substantially, can only high-temperature calcination, and high temperature can only be produced light magnesium oxide, can not produce activated magnesia.
Summary of the invention
Technical problem to be solved in the utility model is: provide the calcining of a kind of Magnesium Carbonate Light 41-45 to be the device of activated magnesia, thereby it can be controlled and burns out activated magnesia easily to temperature.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the Magnesium Carbonate Light 41-45 calcining is the device of activated magnesia, it is characterized in that including combustion engine, roasting kiln, the calcining tower, activated magnesia whirlwind powder collector, drying tower, magnesiumcarbonate whirlwind powder collector, the Magnesium Carbonate Light 41-45 feed bin, Blowing stopper, described combustion engine is connected with the calcining tower by roasting kiln, the calcining tower links to each other with activated magnesia whirlwind powder collector, activated magnesia whirlwind powder collector is connected with magnesiumcarbonate whirlwind powder collector by drying tower, the below of magnesiumcarbonate whirlwind powder collector links to each other with the calcining tower by pipeline and Blowing stopper, and feed bin links to each other with drying tower by self-conveyor feed.
Press such scheme, described magnesiumcarbonate whirlwind powder collector upper end links to each other with sack cleaner by pipeline, is connected with induced draft fan on the sack cleaner, and described sack cleaner lower end links to each other with the calcining tower by pipeline.
Press such scheme, the lower end of described magnesiumcarbonate whirlwind powder collector and activated magnesia whirlwind powder collector also is respectively arranged with Blowing stopper.
The utility model has the advantages that: adopt the distribution of Sweet natural gas calcining machine, high-temperature gas directly contacts temperature with Magnesium Carbonate Light 41-45 and can adjust arbitrarily for 750 ℃~950 ℃, the continuous discharging of continuously feeding, in 5 minutes, finish calcining, produce activated magnesia, quality product meets the HG/T2573-2006 standard, adding tail gas can recycle for 240 ℃~300 ℃, material cools off system below 40 ℃, can directly pack, the structure novelty, energy-saving and cost-reducing, the calcining furnace and drum-type calcining furnace at intermittence that can replace present industry practicality, finishing by the Magnesium Carbonate Light 41-45 calcining is activated magnesia.
Description of drawings
Fig. 1 is the equipment of light magnesium oxide for the calcining of traditional lightweight magnesiumcarbonate;
Fig. 2 is an one-piece construction synoptic diagram of the present utility model.
Embodiment
Pass through the detailed description the utility model of embodiment below in conjunction with accompanying drawing.
The Magnesium Carbonate Light 41-45 calcining is the device of activated magnesia, include combustion engine 12, roasting kiln 13, calcining tower 14, activated magnesia whirlwind powder collector 4, drying tower 5, magnesiumcarbonate whirlwind powder collector 6, Magnesium Carbonate Light 41-45 feed bin 9, Blowing stopper 10, described combustion engine 12 is connected with calcining tower 14 by roasting kiln 13, calcining tower 14 links to each other with activated magnesia whirlwind powder collector 4, activated magnesia whirlwind powder collector 4 is connected with magnesiumcarbonate whirlwind powder collector 6 by drying tower 5, the below of magnesiumcarbonate whirlwind powder collector 6 links to each other with calcining tower 14 by pipeline and Blowing stopper 10, feed bin 9 links to each other with drying tower by self-conveyor feed, described magnesiumcarbonate whirlwind powder collector 6 upper ends link to each other with sack cleaner 7 by pipeline, be connected with induced draft fan 8 on the sack cleaner, described sack cleaner 7 lower ends link to each other with calcining tower 14 by pipeline, and the lower end of described magnesiumcarbonate whirlwind powder collector 6 and activated magnesia whirlwind powder collector 4 also is respectively arranged with Blowing stopper.
Workflow of the present utility model is: Sweet natural gas is through combustion engine 12 distributions, automatically adjusting the tolerance temperature according to required temperature is about 750 ℃~950 ℃ and enters roasting kiln 13 mixed firings, Magnesium Carbonate Light 41-45 enters calcining tower 14 by pipeline, be sintered into active magnesium oxide in short period of time, enter magnesium oxide whirlwind powder collector 4 then, 800 ℃ of tail gas that come out from top enter drying tower 5, remove magnesiumcarbonate whirlwind powder collector 6 again, gas is through sack cleaner 7 dedustings, collected dust by helical feed to the calcining tower 14, secondary is mended into normal temperature air, controlled temperature is at 240 ℃~300 ℃, 240 ℃~300 ℃ tail gas removes induced draft fan 8, discharges at last, enters other dry workshop sections and recycles; The material of Magnesium Carbonate Light 41-45 feed bin 9 directly enters drying tower 5 bottom heatings, enters magnesiumcarbonate whirlwind powder collector 6 then, enter the calcining tower through Blowing stopper 10 again, be sintered into activated magnesia, enter activated magnesia whirlwind powder collector 4 at last, cool off crushing packing again.
