Problems solved by technology

[0002] Microwave heating is widely used in the fields of wood and food drying, microwave sterilization, road maintenance machinery, etc. The heating of asphalt recovered from plant-mixed heat recycling equipment generally uses methods such as gas heating, drying cylinder arm heating, and infrared heating. The temperature of these heating methods is difficult. Control, reach 180° to age the asphalt, and the heat loss is serious, the heating time is long, a large amount of toxic gas and smoke are produced, and the environment is polluted

Abstract

The invention relates to a recycled asphalt microwave heating device which comprises an agitator kettle, an agitator shaft, a vapor outlet, a weighting sensor, a magnetron and an assorted wave guide. The agitator shaft is riveted and welded on a frame and is provided with an agitator arm and an agitator blade shaft; a chute preventing structure is arranged around a door of a microwave weighting and heating system and is provided with a deformed channel structure in the door; the side wall of a cylinder body is provided with a ceramic window, the magnetron produces microwave; and an infrared thermometer is used for A / D-converting acquired current signals into temperature digital signals identified by a PLC. The recycled asphalt microwave heating device has rapid heating speed, uniform heating, energy saving, high efficiency, easy control and environment protection without pollution, can not pollute the environment because the microwave can heat asphalt mixture without producing poisonous gases and smoke and can improve the labor condition.

Description

Technical field: [0001] The invention relates to a construction machine, which is widely used in the fields of wood and food drying, microwave sterilization, road surface maintenance machinery and the like through microwave heating, in particular to a recycled asphalt microwave heating device for mixed heat regeneration processing in a recycled asphalt plant. Background technique [0002] Microwave heating is widely used in the fields of wood and food drying, microwave sterilization, road maintenance machinery, etc. The heating of asphalt recovered from plant-mixed heat recycling equipment generally adopts methods such as gas heating, drying cylinder arm heating, and infrared heating. The temperature of these heating methods is difficult. Control, reach 180° to age the asphalt, and the heat loss is serious, the heating time is long, and a large amount of toxic gases and smoke are produced, polluting the environment. Contents of the invention [0003] In order to solve the ...
