Asphalt pavement milling material plant mixing and hot regeneration integrated system

Abstract

The utility model provides an asphalt pavement milling material plant mixing and hot regeneration integrated system which comprises a raw material bin used for storing asphalt milling materials and conveying the milling materials to a regenerated material drying cylinder through a feeding conveying belt for heating treatment. And a spiral conveying device is arranged in the regenerated material drying cylinder, so that the materials are uniformly heated in the rotating process. The heating device is connected to the left side of the reclaimed material drying cylinder, comprises a high-temperature combustion chamber and a combustor and is used for providing a stable heat source. A temperature sensor is arranged in the regenerated material drying cylinder, and the heating condition of the regenerated material is monitored through the temperature sensor, so that the optimal heating temperature is ensured. And the top of the regenerated material drying cylinder is connected with a flue gas treatment device. Smoke generated in the heating process enters the condensation dust removal chamber through the smoke inlet pipeline, after particles are preliminarily removed through condensation, the smoke enters the water film atomization spraying chamber, and smoke dust is adsorbed through spraying water mist. After spraying is completed, waste gas is exhausted into an exhaust chimney through an induced draft fan, and it is ensured that environment-friendly emission meets the standard.
