Embodiment 1

[0024] like figure 1 , figure 2 As shown, the present embodiment provides a melamine foam uniformity foaming device, comprising a body of furnace 1 and multiple groups of microwave devices, and the front and rear side walls of the body of furnace 1 are respectively provided with a feed door 7 and a discharge door, each group The microwave device includes a microwave source 2 and a waveguide 3. The microwave source 2 is a split-type multi-unit magnetron combined microwave source 2 with a total power of 16-30 kilowatts. The operating frequency of each unit magnetron is 915 MHz.

[0025] The microwave source 2 is arranged at one end of the waveguide 3, and the waveguide 3 is divided into a first branch pipe 3-1 and a second branch pipe 3-2 by a power divider 4, and the first branch pipe 3-1 is arranged in the furnace On the top wall of the furnace body 1, the second branch pipe 3-2 is arranged outside the bottom wall of the furnace body 1, and the top microwave feeding port 5 i...

Embodiment 2

[0029] like figure 1 , image 3 As shown, this embodiment provides a melamine foam uniformity foaming device.

[0030] Among them, there are 2 top microwave feed ports 5 arranged on each group of first branch pipes 3-1, and 2 bottom microwave feed ports 6 arranged on each group of second branch pipes 3-2, adjacent to each other. The distance between the top microwave feed port 5 and the bottom microwave feed port 6 along the width direction of the furnace body 1 is 120mm. The schematic diagram of the microwave feed port distribution is shown in image 3 As shown, the dotted line in the figure indicates the microwave feed port on the bottom wall.

[0031] Other structures of this embodiment are the same as those of Embodiment 1, and will not be repeated here.

Abstract

The invention discloses a melamine foam uniform foaming device and belongs to the field of microwave foaming. The foaming device includes an oven body and multiple sets of microwave devices, wherein the front and rear side walls of the oven body are separately provided with a feeding door and a discharging door. Each set of microwave device includes a microwave source and a wave conduit, wherein the microwave source is arranged at one end of the wave conduit, the wave conduit is divided into a first branch pipe and a second branch pipe by a power splitter, the first branch pipe is arranged onthe top wall of the oven body, the second branch pipe is arranged outside the bottom wall of the oven body, top microwave feeding mouths are arranged on the connection surface between the first branchpipe and the oven body, bottom microwave feeding mouths are arranged on the connection surface between the second branch pipe and the oven body, and the top microwave feeding mouths and the bottom microwave feeding mouths are staggered in the length and width directions of the oven body. The melamine foam uniform foaming device has the advantages of good matching between the microwave feeding mouths, low microwave reflection rate, uniform energy density, good coupling with materials, high heating efficiency, small microwave leakage, safe use and the like.

Description

technical field [0001] The invention belongs to the technical field of microwave foaming, and in particular relates to a uniform foaming device for melamine foam. Background technique [0002] Melamine foam is a new type of foam plastic with a low-density three-dimensional grid structure prepared with melamine as the main raw material and with a porosity as high as 99.9%. It has excellent sound absorption performance, flame retardancy, heat insulation performance, insulation, Moisture and heat resistance stability, safety and sanitation and secondary processing performance, etc. Melamine foam plastics have broad application prospects in fields such as construction, transportation, vehicle manufacturing, acoustic engineering, electronic information, and object surface cleaning and decontamination. [0003] Melamine foam is produced from melamine formaldehyde resin through a continuous foaming process. The continuous foaming device used in the continuous foaming process inclu...
