Microwave heating wall

Abstract

The invention discloses a microwave heating wall. The microwave heating wall comprises a frame, a microwave heating unit array, a cooling system, leveling systems and a microwave leak preventing device, wherein the microwave heating unit array is arranged in the frame and formed by arranging a plurality of microwave heating units in an array manner, and each microwave heating unit comprises a magnetron and a waveguide; with adoption of the array combination in which straight planes and inclined planes of adjacent waveguides of adjacent columns are opposite, the waveguides of adjacent columns are mounted in opposite directions of 180 degrees; the cooling system is used for cooling the magnetrons in the microwave heating unit array during work; the leveling systems are mounted at four foot positions of the heating wall. The magnetrons are cooled by the cooling system and can work for a long time accordingly; the leveling systems are used for keeping levelness of a wall body with the ground and preventing microwave leak; the microwave leak preventing device further prevents microwave leak.

Description

technical field [0001] The invention relates to a microwave heating wall, which is suitable for road maintenance vehicle equipment. Background technique [0002] The core components of the heating wall are composed of multiple magnetrons and waveguides, and the working conditions of the heating wall determine that the heating density of the heating wall must be large, and the longitudinal temperature gradient of the road surface must be perpendicular to the heating surface and must be uniform; The working conditions determine that the distance between the waveguide arrays of the heating wall should not be too large and the emitted microwaves must be perpendicular to the heating surface; however, if the distance between the waveguide arrays is too small, there will be mutual interference, superposition and coupling between the microwaves radiated by different waveguides. Interference, the efficiency of microwave heating is reduced or heating offset occurs, heating dead zone a...

[0002] The core components of the heating wall are composed of multiple magnetrons and waveguides, and the working conditions of the heating wall determine that the heating density of the heating wall must be large, and the longitudinal temperature gradient of the road surface must be perpendicular to the heating surface and must be uniform; The working conditions determine that the distance between the waveguide arrays of the heating wall should not be too large and the emitted microwaves must be perpendicular to the heating surface; however, if the distance between the waveguide arrays is too small, there will be mutual interference, superposition and coupling between the microwaves radiated by different waveguides. Interference, the efficiency of microwave heating is reduced or heating offset occurs, heating dead zone and offset dead zone may appear, which affects the heating uniformity of asphalt mixture; it can be seen that the shape of the waveguide and the formation of the waveguide have a great influence on the quality and time of heating the road surface It is very important, so it is urgent to develop a new waveguide array to improve the heating effect
