Problems solved by technology

There are following defects in use. First, the fuel refined propane used by the infrared radiator is not produced in the country and must be imported from abroad; second, it is difficult to effectively and timely control the temperature of infrared radiation heating during road surface repair construction. It is easy to cause the road surface to overheat, and form a large amount of harmful smog, polluting the environment; third, the infrared radiation heater communicates with the atmosphere when heating the road surface, and the road surface is oxidized seriously, which affects the regeneration quality

Abstract

The invention relates to a hot air cycle heater of pitch road, which comprises a front heater, a back heater, a hot air furnace, a combustion fan, a high-temperature cycle fan, a control system, and a burner, wherein the front and back heaters via the driving device are connected to the frame; the burner is at the air inlet of hot air furnace; the combustion fan and the high-temperature cycle fan are parallel between the air inlet and air outlet of hot air furnace; the air outlet of hot air furnace via the air tube is connected to the front and back heaters; the air inlet of high-temperature cycle fan via the air tube is connected to the hot air furnace; the air outlet via the air tube is connected to the front and back heaters. The invention can burn light diesel to heat air and guide it into certain speed, to heat several road sections at the same time, and it can recycle hot air.

Description

technical field [0001] The invention mainly relates to the field of asphalt pavement maintenance machinery and equipment, in particular to an asphalt pavement hot air circulating heating device. Background technique [0002] In-situ heat regeneration comprehensive equipment mixer is a construction machine that forms a new road surface by heating the road surface, loosening, stirring and paving. The in-situ heat regeneration comprehensive equipment remixer in the prior art adopts infrared radiation heating, and the fuel used is refined propane. There are the following defects in use. First, the fuel pure propane used in the infrared radiator is not produced in China and must be imported from abroad; second, it is difficult to effectively and timely control the temperature of infrared radiation heating during road repair construction. It is easy to cause overheating of the road surface, and a large amount of harmful smoke is formed, which pollutes the environment; third, the ...
