Waste heat utilization device for microwave pavement heating equipment and use method

Abstract

The invention discloses a waste heat utilization device for microwave pavement heating equipment and a use method. The waste heat utilization device for the microwave pavement heating equipment comprises a base, a wind direction plate, a rotation shaft, fixed frames, a wind wheel, a heat insulation layer, a wind supply channel, a motor, a tool box, a tool box support and a metal chain curtain. The waste heat utilization device for the microwave pavement heating equipment has the advantages that the wind direction plate can rotate around the rotation shaft so as to realize angle regulation, the angle of hot wind output from the wind supply channel and blown to a pavement needing heating can be adjusted, and the heat insulation layer good in heat insulation property is arranged outside the wind supply channel so that the loss of the heat energy in the wind supply channel can be lowered; the rotation speed of the motor can be freely adjusted; the rotation speed of an impeller can be adjusted according to the heat energy generated by a magnetron, the impeller is made of high-strength plastic light in weight and high in corrosion resistance, and therefore the service life of the whole device can be prolonged; the tool box is arranged at the upper part of the wind supply channel, can contain multiple tools and is convenient to take and carry; the metal chain curtain is arrange at the outlet of the wind supply channel and can prevent microwave leakage.

Description

technical field [0001] The invention relates to microwave road surface heating equipment, in particular to a waste heat utilization device for microwave road surface heating equipment, and belongs to the field of microwave road surface heating equipment. Background technique [0002] Microwaves are a form of energy (not heat), but can be converted to heat in a medium. The reaction of materials to microwaves can be divided into four situations: (1) penetrating microwaves; (2) reflecting microwaves; (3) absorbing microwaves; (4) partially absorbing microwaves. [0003] Generally, in the field of energy processing, most of the processed materials are dielectric materials, and dielectric materials usually absorb microwave energy to varying degrees. The mutual coupling between dielectric materials and microwave electromagnetic fields will cause various power dissipations to achieve the purpose of energy conversion. There are many ways of energy conversion, such as ion conduction...

AI Technical Summary

Problems solved by technology

[0004] Microwave heating technology is widely used in practice, especially in some asphalt pavement heating and repair work. The existing microwave pavement heater is composed of one or more magnetrons. A large amount of heat energy will be generated, but in reality, according to the different conditions of the road surface, when the road surface does not need so much heat energy, in the structure of microwave heating equipment in the prior art, the remaining heat energy will pass through cooling holes or water cooling. If it is discharged, the remaining heat energy cannot be rationally utilized, so a large amount of heat energy will be lost, causing a large amount of waste of heat energy and greatly reducing the heating efficiency, and polluting the environment; furthermore, the microwave road surface heating equipment in the prior art During use, it was found that the existing microwave road surface heating equipment is cumbersome to use and has many functions, but it is not practical. Many functions cannot be combined with the actual situation, and there are too many operating steps, which is very inconvenient to operate, and even requires professional personnel to operate. Caused inconvenience in use and increased overall cost, and greatly lacked practical performance
