Heating wall for asphalt pavement maintenance vehicle
The invention discloses a heating wall for an asphalt pavement maintenance vehicle and belongs to the technical field of asphalt pavement maintenance equipment. The heating wall comprises a variable power combustor, an electric heating filter, an air sieving plate (3), a high-temperature inlet sensor, a combustion chamber, an air conveying channel (6), a high-temperature reflection film, an asbestos board, a high-temperature outlet sensor, a heat exchange bent pipe, a heat-preservation layer, an air returning groove, an air director, a flow equalizing plate, a hot draught fan, an air inlet pipe and an air outlet pipe. According to the heating wall disclosed by the invention, the temperature of a whole heating process is controllable; the power change of the combustor is controlled through the detection by the temperature sensor so that a pavement is prevented from being burnt by over-high pavement temperature and asphalt ageing is avoided; the pavement temperature in the heating process is constant and the heat conduction efficiency is the highest; the temperature gradient of the asphalt pavement from top to bottom is small and the heating is uniform; and fuel is relatively sufficiently combusted, less waste gas is discharged, the economical efficiency of the fuel is relatively good and the construction efficiency is relatively high.
