Abstract
A rotary kiln device for manufacturing building material ceramsite by calcining coal gangue is characterized in that the front end of a kiln body is provided with a coal gangue inlet, the rear end of the kiln body is provided with a coal gangue outlet, the rear end of the kiln body is provided with a burner, three blowers are arranged on the periphery of the kiln body, air outlets of the blowers are positioned in the kiln body, and air outlets of the blowers face the front end of the kiln body; the utility model discloses very big improvement the burn-off rate of gangue, improved product quality, reduced fuel consumption and manufacturing cost, the invention simple structure, design benefit, safe in utilization, excellent in use effect is fit for generally popularizing and applying.
Description
Technical Field
The utility model relates to a gangue calcines ceramic equipment field for the building materials, especially relates to a gangue calcines rotary kiln device that makes building materials haydite usefulness.
Background
The rotary kiln is used for firing the gangue ceramsite, the gangue is ground into particles of about 10 mm, the particles are sent into the rotary kiln and are subjected to high-temperature roasting to obtain high-strength building material ceramsite, the gangue contains about 10% of carbon, in the firing process of the rotary kiln, if the carbon contained in the ceramsite material is not burnt, the compressive strength of the ceramsite can be reduced, the product quality of the ceramsite is influenced, the carbon in the ceramsite is burnt, the carbon content in the ceramsite is reduced, the strength of the ceramsite is enhanced, the heat in the rotary kiln is increased due to the burning of the carbon, the whole energy consumption is reduced, a large amount of air is required for the burning of the carbon, the air enters from a burner end as secondary air, a burning system is disordered, the heat in a high-temperature section is taken away due to the large amount of air, the effective high-temperature burning cannot be formed, and the burn-out rate of the gangue is improved, can burn off the carbon in the middle of the ceramsite without destroying the burning working condition of the high-temperature section, and simultaneously achieves the effect of reducing fuel consumption, thereby becoming a technical problem which is difficult to solve for a long time.
In view of the above, a rotary kiln device for calcining coal gangue to manufacture building material ceramsite has been developed.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the not enough among the prior art, provide a gangue and calcine the rotary kiln device of making building materials haydite usefulness, very big improvement the burn-off rate of gangue, improved product quality, reduced fuel consumption and manufacturing cost, the utility model discloses simple structure, design benefit, it is safe in utilization, excellent in use effect is fit for generally popularizing and applying.
The utility model discloses a realize above-mentioned purpose, adopt following technical scheme: a rotary kiln device for manufacturing building material ceramsite by calcining coal gangue comprises: the kiln body, the blower and the burner; the front end of the kiln body is set as a coal gangue inlet, the rear end of the kiln body is set as a coal gangue outlet, the rear end of the kiln body is provided with a burner, three air blowers are arranged on the periphery of the kiln body, air outlets of the air blowers are located in the kiln body, and air outlets of the air blowers face the front end of the kiln body.
The kiln body is internally provided with a preheating zone, a first calcining zone and a second calcining zone from front to back in sequence, the temperature in the preheating zone is less than 500 ℃, the temperature in the first calcining zone is less than 1000 ℃, the temperature in the second calcining zone is more than or equal to 1000 ℃, and the three blowers are uniformly distributed on the periphery of the kiln body corresponding to the first calcining zone.
The working principle is as follows: the coal gangue enters from the front end of the kiln body, the coal gangue gradually moves to the rear end of the kiln body along with the rotation of the kiln body, the burner provides hot air for the calcination of the coal gangue in the kiln body, the flow of the hot air and the coal gangue in the kiln body is reverse, the preheating zone preheats the coal gangue, the preheated coal gangue moves to a calcination zone along with the rotation of the kiln body, the air blower blows a certain amount of air into the feeding end of the kiln body, the entered air is burnt with carbon in the coal gangue, because the air enters from the rear part of the flame of the burner and does not enter as secondary air from the end part of the rotary kiln, the high temperature zone of the flame is not influenced, more fuel is not needed to be added, the calcination zone is prolonged, meanwhile, because of the burning of the carbon, the material temperature is improved, the fuel consumption of the burner is reduced, and two purposes of improving the product quality and saving the fuel are achieved, the heat below the temperature in the first calcining zone enters the preheating zone along with air to preheat the coal gangue in the preheating zone, CO produced by burning the coal gangue in the kiln body is discharged from a waste gas outlet at the front end of the kiln body, high-strength building material ceramsite is obtained after burning the coal gangue, and the building material ceramsite is discharged from a coal gangue outlet at the rear end of the kiln body.
The utility model has the advantages that: the ignition temperature initial point of carbon is 500 ℃, in order to burn off carbon completely, with between 1000 ℃ to 500 ℃, as the combustion area of carbon, call for the district of calcining, be less than this temperature, call for the preheating zone, set up two district of calcining, combustion-supporting wind divides twice entering rotary kiln, has prolonged the district of calcining, helps improving the burn-off rate of gangue, and helps fuel economy, the utility model discloses very big improvement the burn-off rate of gangue, improved product quality, reduced fuel consumption and manufacturing cost, the utility model discloses simple structure, design benefit, safe in utilization, excellent in use effect is fit for generally popularizing and applying.
