Embodiment Construction

[0017] Such as figure 1 As shown, the portable road repair microwave heating device of the present invention mainly includes a reflector 6 and a microwave generator 1 . The bottom of reflector 6 is equipped with moving wheel 12, to realize the movement of this device, moving wheel 12 can be universal wheel. A microwave generator 1 is provided on the outside of the top of the reflector 6 , and an energy feed port 4 is provided on the inside of the top of the reflector 6 , and a waveguide 3 is connected between the microwave generator 1 and the energy feed port 4 . The microwave generator 1 is provided with a radiator 2 . The outside of the reflection cover 6 is provided with a thermal insulation shell 5 to prevent heat loss. In order to prevent the operator from being harmed by the microwave diffusion, a microwave absorbing coating 7 is coated on the lower part of the reflector 6 to absorb the diffused microwave. The reflector 6 is provided with a high temperature inlet 11 ....

Abstract

A moveable pavement restoration microwave heating apparatus comprises a reflection cover and a microwave generator, the microwave generator is arranged at the outer side of the top of the reflection cover, the inner side of the top of the reflection cover is provided with an energy feedback port, the microwave generator is connected with the energy feedback port via a waveguide tube, the inner side of the lower part of the reflection cover is coated with a microwave absorption coating, the exterior of the microwave absorption coating is provided with a cooling loop, the cooling loop is connected with a high-temperature inlet on the reflection cover via a pipe, and the pipe is connected with a circulating pump. Majority of microwave generated by the microwave generator is absorbed by a pavement, minority of microwave is absorbed by the microwave absorption coating and is transformed into heat, the heat is absorbed by air in the cooling loop and the air forms a high-temperature gas and enters into the reflection cover and bakes the surface-layer pavement. The apparatus realizes dual heating of the restored pavement through microwave and the high-temperature gas, realizes the rapid heating requirement of the restored pavement, satisfied rapid solidification requirement, and is high in energy utilization rate.

Description

technical field [0001] The invention relates to a mobile heating device for heating the road surface when repairing the damaged road surface, and belongs to the technical field of road surface repair heating. Background technique [0002] Hardened pavement is generally made of concrete, asphalt, resin concrete and other materials. Defects such as damage may occur during use, especially the airstrip, which is more vulnerable to damage under harsh conditions, especially in wartime. It needs to be repaired in a timely manner. The repair materials can not only meet the service performance, but also have good compatibility with the original materials, and can meet the service requirements in a short time. [0003] The restorative materials of the existing repair damaged concrete (asphalt) pavement mainly contain: 1. ordinary concrete, is exactly the artificial stone material that is cemented material with cement, and sand, stone are main aggregate preparation; 2. polymer modifie...
