Description
Technical field
The utility model relates to material and air-flow reverse movement calcined kaolin rotary kiln in a kind of the calcined kaolin rotary kiln, particularly kiln.
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 technological 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, but prove through production practices, this calcined kaolin rotary kiln from external introduction, not only cost an arm and a leg, but also there is certain weak point, as 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 production capacity of equipment.Just there are the problems referred to above in this calcined kaolin rotary kiln in actual production, as the calcined kaolin rotary kiln of domestic certain company from external import, its designed capacity is 10,000 tons of annual output calcined kaolins, and actual production 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 steady production.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 the thermal efficiency yet.
Summary of the invention
Goal of the invention of the present utility model provides material and air-flow reverse movement calcined kaolin rotary kiln in a kind of kiln, 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: material and air-flow reverse movement calcined kaolin rotary kiln in the kiln comprise calcination rotary kiln kiln body, support roller, feed end, discharge end, charging mechanism and the transmission mechanism that is made of motor, reduction box, pinion and gear wheel; Support roller is held calcination rotary kiln kiln body by being fixed on entrusting of calcination rotary kiln kiln body two ends; Gear wheel in the transmission mechanism is contained in an end of calcination rotary kiln kiln body, and its motor rotates by the reduction box driving pinion, and pinion rotates calcination rotary kiln kiln body by gear wheel; Described feed end is lived with the two ends of calcination rotary kiln kiln body with discharge end and is connected, charging mechanism and feed end link, it is characterized in that also comprising the smoke evacuation system that constitutes by 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 the utility model designs smoke evacuation system in feed end one side, make that material and air-flow in the calcination rotary kiln kiln body are reverse movement, 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 the thermal 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 di-iron trioxide, 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 axial 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 calcination atmosphere in the calcination rotary kiln kiln body 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, running is reliable continuously, and easy to maintenance, 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
