Problems solved by technology
[0004] Among the above-mentioned heating methods, the electric heating method usually uses the electric heating rod to contact the screed bottom plate, so the temperature rise of the bottom plate area close to the heating rod is faster, and the temperature rise of the bottom plate area away from the electric heating rod is slower, resulting in uneven heating of the bottom plate
The gas heating and oil heating methods not only have heat convection with the bottom plate, but also have heat convection with the surroundings, resulting in serious waste of heat
The combustion control system of far-infrared radiation heating is complicated, difficult to maintain, and will also generate exhaust gas pollution

The invention discloses an infrared heating ironing plate which comprises a plurality of sections of ironing plates; each section of ironing plate comprises a bottom plate and a plate rack frame body; a heating bin is arranged between the bottom plate and the plate rack frame body; the heating bin comprises a bin body defined by a bin body cover and a bin body bottom frame; the upper part of the bin body is provided with an air inlet pipe; the bin body cover is internally provided with a gas dispersion plate and an insulating plate which are arranged under the air inlet pipe; the insulating plate is connected with a preheating tube; an infrared catalytic plate is connected under the preheating tube and is used for enabling gas and air to have a full oxidation reaction; and a protective net which is arranged on the bin body bottom frame is arranged under the infrared catalytic plate. After the structure is adopted, an ironing bottom plate can be evenly heated within a short time; the catalytic infrared heating is a non-flame type reaction, the catalyzing temperature of the catalytic infrared heating is lower than the ignition point and is free from the hidden danger of explosion, and harmful gases such as CO, NO and the like are not produced, so that the infrared heating ironing plate is safe and free from pollution; the infrared heating ironing plate is safe and reliable in heating; and the heating requirement of the ironing plate of a paver can be met.
Description
technical field [0001] The invention relates to an asphalt paver screed, in particular to an infrared heating screed, which belongs to the technical field of road machinery supporting equipment. Background technique [0002] Paver is one of the important equipment for road construction. In order to reduce the bonding between the screed base plate and the hot asphalt material during construction, the screed base plate is required to have a heating function. [0003] At present, there are mainly the following heating methods for the screed: (1) gas heating, using the acrylic kang gas combustion device to directly heat the screed; (2) electric heating, using electric heating tubes to heat the screed; (3) oil heating, The screed is heated by burning diesel oil; (4) far-infrared radiation heating, the heat energy can be converted into far-infrared electromagnetic waves through the gas combustion device and the far-infrared radiation material, and then the screed is heated by this...
