Heating device giving consideration to secondary temperature rise of asphalt mixture and pavement thermal connection

Abstract

The invention discloses a heating device giving consideration to secondary temperature rise of an asphalt mixture and pavement thermal connection, and relates to the technical field of road maintenance equipment. The hot-blast stove comprises a rack, a secondary temperature rising main heating wall and a hot-blast stove assembly, the secondary temperature rising main heating wall is fixedly arranged on the rack; the two opposite sides of the secondary temperature-raising main heating wall are respectively hinged with a thermal connection auxiliary heating wall, the thermal connection auxiliaryheating walls are communicated with the secondary temperature-raising main heating wall, the hot blast stove assembly is arranged at the top of the secondary temperature-raising main heating wall, and the output end of the hot blast stove assembly is communicated with the secondary temperature-raising main heating wall. An asphalt material secondary temperature rise and pavement thermal connection combined heating process is adopted, and meanwhile, the heating device is arranged after a new asphalt mixture is added, so that the problem of poor regeneration quality caused by low regenerated material paving temperature due to low temperature of the new asphalt mixture is solved.

Description

technical field [0001] The invention relates to the technical field of road maintenance equipment, in particular to a heating device that takes into account the secondary heating of asphalt mixture and thermal connection of road surfaces. Background technique [0002] The remixer is the main machine of the in-situ heat regeneration complete set of equipment. It is located behind multiple pavement heating machines and road milling machines. equipment. After the asphalt pavement is heated and milled, a 200mm to 300mm thick asphalt pile will be gathered up. The temperature of the pile is usually 120 to 130°C, and then a certain proportion of new asphalt mixture is added to the pile for gradation adjustment, often Multiple road surface heating machines and road milling machines need to be moved forward 20m to 30m, and then the dump truck crosses the thick stockpile and rides on the stockpile to add new asphalt mixture to the hopper of the remixer. The temperature loss of the a...

Problems solved by technology

[0004] The purpose of the present invention is to provide a heating device that takes into account the secondary heating of the asphalt mixture and the thermal connection of the road surface. The heating device is placed after the addition of the new asphalt mixture, which overcomes the problem of paving recycled materials caused by the low temperature of the new asphalt mixture. The problem of poor regeneration quality caused by low temperature
