Description
Technical field
The utility model relates to a kind of calcined kaolin rotary kiln, particularly rotary kiln with resistor furnace for heating and calcining kaolin.
Background technology
Restricting China's production high quality superfine calcined kaolin for a long time (is granularity≤2 μ m, content 〉=90%, whiteness 〉=90%) a great difficult problem is that existing kaolin calcined equipment and technology do not pass a test, and is difficult to satisfy the processing requirement of producing the high quality superfine calcined kaolin.Though country has also dropped into great amount of manpower and material resources, has carried out years of researches and exploitation for this reason, never obtain satisfied effect.In order to produce high-quality superfine calcined kaolin, have to from external introduction calcined kaolin rotary kiln device and calcining technology.The calcined kaolin rotary kiln of this external introduction though can produce high-quality superfine calcined kaolin, proves through production practice, and this calcined kaolin rotary kiln from external introduction not only costs an arm and a leg, but also has certain weak point.Main has: 1, this calcined kaolin rotary kiln is to be that thermal source carries out indirect heating with oil or coal gas, and this has just caused the complicated of thermal technology's control, has increased manufacturing cost.Simultaneously, because the flue gas that burning produces not only can be taken away a large amount of heat energy, reduce heat utilization efficiency, but also bring the smoke contamination problem to environment.2, this calcined kaolin rotary kiln, what adopt is the calcining technology of interior material of kiln and airstream in kiln following current campaign (i.e. motion in the same way), this just might make to be mixed in to be deposited to when particulate dust that the end calcining in the air-flow finishes is blown near discharge end by air-flow near feed end and calcine in the material of finishing, thereby has polluted product.In order to produce high-quality product, just must increase calcination time like this, thereby reduce the throughput of equipment.Just there are the problems referred to above in this kaolin calcined rotary kiln in actual production, as the kaolin calcined rotary kiln of domestic certain company from external import, its designed capacity is 10,000 tons of annual output calcined kaolins, and actual capacity has only 0.6 ten thousand tons/year.Domestic another company also from external import two kaolin calcined rotary kilns, existing so far 3 years, also the end can stably manufactured.This in addition kaolin calcined rotary kiln is because its material and air-flow are following current campaign in the same way, and the physics latent heat that they are taken away does not obtain utilizing yet, and has correspondingly reduced thermo-efficiency yet.
Summary of the invention
Goal of the invention of the present utility model provides a kind of rotary kiln with resistor furnace for heating and calcining kaolin, to solve the weak point that existing calcined kaolin rotary kiln exists, produces the high quality superfine calcined kaolin.
In order to realize the foregoing invention purpose, the technical solution adopted in the utility model is: rotary kiln with resistor furnace for heating and calcining kaolin comprises calcination rotary kiln kiln body, support roller, feed end, discharge end, charging mechanism and the transmission rig that is made of electric motor, reduction box, pinion(gear) and master wheel; Support roller is held calcination rotary kiln kiln body by being fixed on entrusting of calcination rotary kiln kiln body two ends; Master wheel in the transmission rig is contained in an end of calcination rotary kiln kiln body, and its electric motor rotates by the reduction box drive pinion, and pinion(gear) rotates calcination rotary kiln kiln body by master wheel; Described feed end is lived with the two ends of calcination rotary kiln kiln body with discharge end and is connected, and charging mechanism and feed end link, and it is characterized in that has resistance furnace in the outer setting of calcination rotary kiln kiln body.
The further improved technical scheme that the utility model adopts is: it also comprises the fume exhaust system that is made of smoke exhaust pipe, flue dust recovery tower, chimney, smoke exhaust pipe one end is fixedlyed connected with feed end, the other end and flue dust recovery tower link, and are connected with flue valve between flue dust recovery tower and the chimney.
Because it is thermal source that the utility model adopts electricity, carries out indirect heating, makes the thermal technology control simplification, has reduced manufacturing cost, owing to there is not the fume emission that burning produces, promptly improved heat utilization efficiency simultaneously, protected environment again.In addition owing to the utility model designs fume exhaust system in feed end one side, make that intravital material of calcination rotary kiln kiln and air-flow are inverse motion, having solved feed end that existing calcined kaolin rotary kiln exists effectively is mixed in and is deposited to the problem of calcining polluted product in the material of finishing when particulate dust that the end calcining in the air-flow finishes is blown near discharge end by air-flow, saved calcination time, physics latent heat in material and the air-flow is fully utilized, has improved thermo-efficiency.
With regard to the calcining of Coaseries kaolin, material in kiln under 900-1000 ℃ the temperature, the calcination process that main is through deshydroxy and decarburization.In order to guarantee the whiteness of product, must guarantee that the impurity element iron in the material does not generate or the least possible generation ferric oxide, this just requires kiln atmosphere to be controlled under the weakly reducing atmosphere to calcine.
For this reason, the further improved technical scheme of the utility model employing is: adopt shoulder seal ring and radial seal ring to seal between feed end and discharge end and the calcination rotary kiln kiln body.
The utility model can be controlled the intravital calcination atmosphere of calcination rotary kiln kiln flexibly and comfortably by flue valve in addition.
Owing to adopted technical scheme as above, the utility model is compared with existing calcined kaolin rotary kiln, it is simple to have technological operation, continuous operation is reliable, and is easy to maintenance, and the calcination product quality reaches the advanced level of similar products at home and abroad, constant product quality, energy consumption is low, and production process is pollution-free, the advantage that the device fabrication price is low
