Embodiment 1

[0038] Such as figure 1 , figure 2 As shown, this embodiment provides a microwave heating device, which is mainly used to achieve the purpose of rapidly heating non-microwave absorbing materials by using microwaves. Specifically, the microwave heating device includes a housing 1, a heat conduction container 2 and a microwave absorbing structure. Wherein, the shell 1 is made of a wave-transparent material for allowing microwaves to penetrate through the shell. The heat-conducting container 2 is arranged in the shell 1, and the heat-conducting container 2 is mainly used for containing the object to be heated, and here, the object to be heated is mainly a non-microwave absorbing material. The microwave absorbing structure is arranged in the shell 1 and contacts the heat conduction container 2 , and is mainly used to absorb microwaves passing through the shell to generate heat, thereby heating the object to be heated in the heat conduction container 2 .

[0039] The microwave ...

Embodiment 2

[0041] Such as figure 1 , figure 2 As shown, this embodiment provides a microwave heating device. Compared with Embodiment 1, the microwave absorbing structure in this embodiment is composed of granular microwave absorbing material 3 filled between the shell 1 and the heat conducting container 2 .

[0042] In this embodiment, the microwave absorbing structure adopts the microwave absorbing material particles surrounding the heat conducting container. Through such arrangement, on the one hand, the particles can fully absorb microwaves, and the heat generated can be fully and evenly transferred to the heat conducting container, realizing the Rapid and uniform heating of the heating object; on the other hand, because the particles are heavier and there are more pores between the particles, even if the gas between the particles heats up sharply, the particles will not leak out; on the other hand, the microwave absorbing material The particles can also act as a support structure ...

Embodiment 3

[0045] This embodiment provides a microwave device. Compared with the above embodiments, the housing in this embodiment includes a housing and a cover. Wherein, the casing is provided with an accommodation cavity, and the accommodation cavity is provided with an opening; the cover body is arranged in cooperation with the opening of the accommodation cavity, and is used to block the opening of the accommodation cavity, so that the accommodation cavity forms a closed space . The heat conducting container and the microwave absorbing structure are accommodated in the accommodating cavity.

[0046] Preferably, the material of the housing is any wave-transparent material among glass, quartz, and heat-insulating bricks; the material of the cover is any wave-transparent material among graphite, glass, quartz, and heat-insulating bricks. These wave-transmitting materials have good wave-transmitting performance and good high-temperature resistance.

Abstract

The invention discloses a microwave heating device and method, relates to the technical field of thermal processing and solves the technical problem that non-microwave absorption materials cannot be rapidly heated through microwaves. According to the main technical scheme, the microwave heating device comprises an outer casing, a heat conductive container and a microwave absorption structure; the outer casing is made of wave-transmitting materials; the heat conductive container is arranged inside the outer casing; the heat conductive container is used for holding heated materials; the microwave absorption structure which is arranged inside the outer casing is in contact with the heat conductive container; the microwave absorption structure absorbs microwaves of the outer casing, rapidly generates heat to heat the heated materials inside the heat conductive container. The microwave heating device and method is mainly used for achieving a purpose of rapidly heating non-microwave absorption materials through the microwaves.

Description

technical field [0001] The invention relates to the technical field of heat treatment, in particular to a microwave heating device and method. Background technique [0002] Microwave heating technology uses electromagnetic waves to transmit energy to the inside of the object to be heated, so that the temperature of the object to be heated can be rapidly raised, heated or matured in a short period of time. Microwave heating technology has the advantages of uniform heating, fast speed, timely control, sensitive response, strong field high temperature, strong microwave heating penetration ability, cleanliness, and no pollution, and is widely used. [0003] However, microwave heating is selective to the object to be heated, and it is mainly used for heating microwave-absorbing materials (the dielectric constant of the material is large and the ability to absorb microwaves is strong); rather than microwave-absorbing materials (the dielectric constant of the material is too small ...
