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. A moving wheel 12 is installed at the bottom of the reflector 6 to realize the movement of the device. The moving wheel 12 may be a universal wheel. A microwave generator 1 is provided on the outside of the top of the reflector 6, an energy feed port 4 is provided on the inside of the top of the reflector 6, and a wave guide 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 reflector 6 is provided with a heat-insulating shell 5 to prevent heat loss. In order to prevent the spread of microwaves from causing damage to the operator, a microwave absorbing coating 7 is coated on the lower part of the reflector 6 to absorb the diffused microwaves. A high temperature inlet 11 is provided on the reflector 6. A cooli...

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 used for heating the road surface when repairing damaged road surfaces, and belongs to the technical field of road repair heating. Background technique [0002] Hardened pavement generally uses materials such as concrete, asphalt, and resin concrete. Defects such as damage may occur during use, especially on airstrips, which are more likely to be damaged in harsh operating conditions, especially during war. It needs to be repaired in time. The repair material can not only meet the use performance, but also have good compatibility with the original material, but also meet the use requirements in a short time. [0003] The existing repair materials for repairing damaged concrete (asphalt) pavement mainly include: 1. Ordinary concrete, which is an artificial stone prepared with cement as the cementing material and sand and stone as the main aggregate; 2. Polymer modified concrete, It is to prepare a special admi...
