Problems solved by technology

However, in this structure, the microwave generator is directly installed on the side wall of the firing furnace. Due to the increase in furnace temperature, it is difficult to achieve absolute heat insulation and more appropriate protection. Microwave devices are easily affected or damaged, reducing microwave service life

Embodiment Construction

[0035] In order to enhance the understanding of the present invention, the implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.

[0036] figure 1 Among them, 1 is a rectangular circular track for moving the kiln car group, with a length of 35,000 mm, a width of 7,000 mm, and a distance of 700 mm between the two rails. The kiln car group moves excessively in the direction of the length and width of the rectangular track; 2 is a three-stage energy-saving Type microwave sintering tunnel furnace with a length of 21,000 mm and a width of 18,000 mm; 3 is the microwave source, during which microwaves are introduced into the sintering furnace through wave guides; 4 is the mobile power system of the kiln car group. The microwave source uses a high-power power supply with a frequency of 915MHZ. The microwave power supply is equipped with a control system that can adjust the microwave output power of the magnetron ...

Abstract

The invention relates to a microwave sintering furnace, in particular relating to a three-section four-door long-tunnel energy-saving type microwave sintering furnace, which comprises a microwave sintering tunnel furnace, tracks and a kiln car and is characterized in that the appearance of the furnace body is in a long box structure, a base is arranged under the furnace body, two tracks are paved, the side surfaces of the furnace wall are provided with equally spaced gate slots and square sliders, and four lifting type steel doors divide the furnace chamber into a cooling section, a sintering section and a preheating section; a hot gas pumping pipeline is arranged between the cooling section and the preheating section; the top part of the tunnel furnace body is provided with a waveguide port; the kiln car is in a box-combined structure and comprises track wheels, a carframe in a steel square frame type structure, an air inlet and a heat-resisting material layer, the front and rear ends of the kiln car are respectively provided with an auricled door bracket, a connecting piece and a groove, and a kiln car group is formed by connecting 1 to 5 kiln cars; and the microwave sintering furnace also comprises three groups of servo motors controlled synchronously and driven systems. Compared with the traditional kiln furnace, the microwave sintering furnace has high heating speed, saves power by 40-50%, shortens time by 1.5h, achieves the aims of saving energy and reducing consumption and improves economic benefit.

Description

technical field [0001] The invention relates to a microwave sintering furnace, in particular to a three-section four-door long tunnel type energy-saving microwave high-temperature sintering furnace. technical background [0002] Microwaves are electromagnetic waves. Microwave is an electromagnetic wave with a frequency of 300 MHz to 300 GHz (wavelength 1 meter to 1 mm), and is usually used in radar and communication technology as information transmission. In modern applications, it has been expanded into a new heat source, which is used for heating and drying in industry and agriculture. [0003] Microwaves have special propagation paths and methods. When there is no obstacle, it propagates in a straight line until attenuation; when there is an obstacle, it either reflects, penetrates or is absorbed by the obstacle. When the obstacle is metal, the microwave will reflect as soon as it hits the metal, and the metal has no way to absorb or conduct it; when the obstacle is in...
