Abstract

The invention discloses a microwave feed port structure based on a wood medium. The microwave feed port structure comprises a heating cavity, four same microwave feed port waveguides, a hot air inlet apparatus, a hot air outlet apparatus and a temperature measurement apparatus, wherein each microwave feed port waveguide adopts a shrink shape; the four same microwave feed port waveguides are connected with the side walls of the heating cavity in a up and down, left and right way; the four same microwave feed port waveguides are used for uniformly feeding microwave energy to the periphery of the heating cavity; the hot air inlet apparatus is connected to one end of the heating cavity while the hot air outlet apparatus is connected to the other end of the heating cavity; and the temperature measurement apparatus is arranged on the heating cavity. By adoption of the microwave feed port structure, the field strength of the wood in the heating process is reinforced while the uniformity of the microwave field strength on each surface of the wood is enhanced, and generation of surface attachment on the microwave shrink feed port structure is reduced, so that a sparking condition in the feed port is further reduced.

Description

technical field [0001] The invention relates to the field of microwave heating system equipment, in particular to a microwave feeder structure based on wood as a medium. Background technique [0002] The research on microwave technology applied to wood at home and abroad began at the beginning of this century, and most of the research mainly focused on the influence of microwave treatment on wood microstructure, permeability, mechanical properties and drying rate. Heating wood with microwaves can change the structure and properties of wood from the inside, greatly improve the permeability of wood, increase the penetration of wood preservatives, and thus improve the effect of wood preservative treatment. [0003] At present, there are very few domestic and foreign microwave industrialized equipment with high power of 915MHz applied to wood puffing devices. Most researchers use small 2450MHz magnetron equipment for research. Due to the frequency limitation of small magnetrons,...
