Bundling tube for microwave oven

Abstract

The invention discloses a bundling tube for a microwave oven, which is installed on the microwave oven and comprises a hollow main body and microwave generators, wherein the outer contour shape of the main body is reduced along a central line, a plurality of microwave generators which are arranged at intervals are arranged on the side wall opposite to an outlet of the main body, and the microwave generators emit microwaves towards one direction. A bundling tube structure is adopted in the invention, so that microwaves emitted by low-power microwave tubes working in group do not damage other magnetrons, and meanwhile, a plurality of beams of microwaves are overlapped, the resonance is amplified, the energy is more centralized, the penetrating effect (depth) is better, and the utilization ratio of the microwaves is high; and a PLC (Programmable Logic Controller) controls the microwave generators to form a rotary microwave field, which is same as the condition that a heated objected rotates ceaselessly while being heated in the microwave oven so that the heating temperature is uniform and no dead angle exists.

Description

technical field [0001] The invention relates to equipment for heating materials by using microwave energy, in particular to a microwave heating furnace for heating asphalt mixture. Background technique [0002] Road transportation is the main artery of economic development, and asphalt pavement occupies a considerable proportion in my country's road pavement due to its advantages of comfort, stability, durability, and good skid resistance. With the rapid development of road construction, asphalt pavement Pavement is used more and more in road construction. However, after long-term use of asphalt pavement, pavement damage will occur due to asphalt aging or abnormal rolling of the pavement, which will lead to uneven road surface and affect the safety and comfort of driving. Therefore, the maintenance of asphalt pavement is very important. Common pavement diseases in asphalt pavement maintenance include pavement cracks, rutting, water damage, surface function damage, potholes, ...

AI Technical Summary

Problems solved by technology

[0007] Although the above two microwave heating devices can heat a certain amount of asphalt mixture anytime and anywhere as required, and have no pollution to the construction environment, the microwave generators of the microwave heating furnace are all arranged on the furnace wall. Since the power of the microwave generator is constant, The amount of single heating material is related to the power or quantity of the microwave generator. To increase the amount of heating material, only high-power microwave generators or more microwave generators can be used. Due to the high price and the limitation of foreign technology , the use of high-power microwave generators is currently unrealistic, and the number of microwave generators installed is limited by the area of ​​the side wall of the microwave heating furnace. If more microwave generators are to be arranged, the volume of the microwave heating furnace will increase; On the one hand, microwave generators are arranged on the peripheral wall of the microwave heating furnace, and there may be mutual interference between adjacent microwave generators and relative microwave generators, which will cause the microwave generators in some positions to be easily damaged, and the failure rate is high, which will affect the construction.
