An energy-saving asphalt mixing plant

Abstract

This application relates to an energy-saving asphalt mixing plant, which includes a feeding belt conveyor, a drying drum, a hot aggregate hoist, an asphalt tank and a mixing pot. The drying drum includes a body and a heating mechanism. The heating mechanism includes a combustion cylinder and an oil gun. , Fuel supply tank and air supply assembly, the gas outlet end of the combustion tube is connected to the body, the oil gun is set in the combustion tube, and the oil outlet of the oil gun is set towards the body, the fuel supply tank is connected to the oil gun, and the air supply assembly includes a supply Air box, fan and multiple air supply pipes, the fan is connected to the air supply box, and the multiple air supply pipes are connected to the combustion cylinder and arranged tangentially to the inner wall of the combustion cylinder, and the multiple air supply pipes are arranged along the direction away from the body Arranged sequentially. In this application, a multi-layer spiral airflow will be formed in the combustion tube, thereby increasing the contact area between fuel and air, reducing the influence of turbulent air flow in the combustion tube on fuel combustion, and finally achieving the effect of increasing fuel combustion sufficiency.

Description

technical field [0001] The application relates to the technical field of asphalt concrete production equipment, in particular to an energy-saving asphalt mixing plant. Background technique [0002] The asphalt mixing plant is a kind of equipment that mixes dry and heated aggregates, fillers and asphalt of different particle sizes according to the design ratio at a specified temperature to form a uniform mixture. The asphalt mixing plant connects various relatively independent devices to form a mixer-centered system. These devices mainly include: cold material device, drying drum, hot aggregate lifting device, vibrating screening device, stirring pot, asphalt tank and finished product silo, etc. [0003] When using the mixer, the ore raw materials of different specifications are transported to the corresponding cold material bin, and then the ore raw material in the cold material bin is transported to the drying drum through the feeding belt conveyor, and the drying drum hea...

AI Technical Summary

Problems solved by technology

[0005] In view of the above-mentioned related technologies, the inventor believes that when the air supply device supplies fresh air to the combustion cylinder, the blower provides air to the combustion cylinder, and the air blown into the combustion cylinder by the blower will interfere with the fuel sprayed by the oil gun, so that The fuel sprayed out of the oil gun is blown further away from the oil gun by the air, and then there is insufficient contact between the fuel and the air that is free to move away from the oil gun, resulting in insufficient fuel combustion
