Description

Technical Field

[0001] The utility model specifically relates to the technical field of laser heating, and more specifically, it is a three-way light input device for a containerless laser heating suspension furnace. Background Art

[0002] A laser heating suspension furnace is a device that uses a laser beam to heat and suspend a sample. The laser heating suspension furnace uses the energy of the laser beam to heat the sample to a high temperature state. At the same time, the sample is suspended in the furnace by gas injection or other means to avoid contact between the sample and the furnace wall, thereby reducing heat conduction and heat loss.

[0003] However, currently, the laser beams of most suspension furnaces are irradiated into the furnace body from the upper part or all around. The laser beam irradiates the surrounding positions of the material, while the bottom of the material cannot be heated. This results in uneven heating of the bottom and surrounding positions of the material, and it takes time for the heat to be fully transferred, resulting in a longer heating time and lower efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a three-way light input device for a containerless laser heating suspension furnace. Through the angular distribution between the upper-end laser light source and the lower-end laser light source, three laser rays irradiate the material from different angles, enabling the material to be evenly heated, thereby improving the heating efficiency.

Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1-6 , the embodiments of the present utility model provide a three-way light input device for a containerless laser heating suspension furnace, including an upper laser heating source at the upper light input position of the suspension furnace and a lower laser heating source at the lower light input position of the suspension furnace. Among them, the upper laser light source is provided with two lasers, which are symmetrically arranged at the upper end of the suspension furnace respectively;

[0028] The suspension furnace includes a suspension furnace body 1 and a base 2. The suspension furnace body 1 and the base 2 are fixedly connected, and a feeding assembly 3 is fixedly installed on the suspension furnace body 1;

[0029] The two lasers of the upper laser light source are arranged on the upper part of the suspension furnace body, and the lower laser light source is located on the side of the suspension furnace body 1. The three lasers of the two upper laser light sources and the lower laser light source are arranged in a circular array.

[0030] In this embodiment, the upper laser light source includes a carbon dioxide laser generator 5 and a support plate 4 for fixing the carbon dioxide laser generator 5. A second reflector 9 for reflecting laser rays is also fixed on the support plate 4. A third reflector 10 and a fourth reflector 11 are also fixed on the side of the support plate 4 close to the suspension furnace body 1.

[0031] In this embodiment, the lower laser light source includes a carbon dioxide laser generator 5 and a first reflector 8 for reflecting laser rays, and the first reflector 8 is fixed on the side of the L-shaped frame 7.

[0032] In this embodiment, a red light coupler 6 is fixed at the end of the carbon dioxide laser generator 5.

[0033] In this embodiment, a support column 22 is integrally provided at the lower part of the base 2, and a bracket 21 for fixing the equalizing disk is further installed on the base 2.

[0034] In this embodiment, a hole is formed inside the base 2, and the first reflector 8 is located directly below the inner cavity of the base 2.

[0035] By adopting the above technical solution, the two first laser emitters and the second laser emitter irradiate the suspension furnace body 1 from three different directions respectively, so that the materials inside the suspension furnace body 1 are irradiated by laser rays at three different angles, making the materials heated more uniformly inside the suspension furnace body 1, and most of the laser rays heat simultaneously, which can improve the heating efficiency.

[0036] In this embodiment, a light-near opening is formed at the end of the support plate 4, and the light-near opening is located between the second reflector 9 and the third reflector 10.

[0037] In this embodiment, a hollow mounting seat is integrally provided at the upper part of the suspension furnace body 1, and there are a plurality of hollow mounting seats.

[0038] In this embodiment, the second reflector 9 and the carbon dioxide laser generator 5 in the upper-end laser light source are respectively installed on the support plate 4 through fasteners.

[0039] In this embodiment, a fixing rod is fixed on one side of the support plate 4 away from the carbon dioxide laser generator 5, and the third reflector 10 and the fourth reflector 11 are respectively fixed to the fixing rod through hoop pieces.

[0040] Specifically, the light incident end of the red light coupler 6 is attached to the light output end of the carbon dioxide laser generator 5, so that the laser rays emitted by the carbon dioxide laser generator 5 enter the inside of the red light coupler 6, and after being coupled with the red light inside the red light coupler 6, they are emitted from the light output end of the red light coupler 6.

[0041] Specifically, the laser rays emitted by the carbon dioxide laser generator 5 in the lower-end laser light source are irradiated onto the first reflector 8 after being coupled by the red light coupler 6, and after being reflected by the first reflector 8, they enter the inside of the suspension furnace body 1 through the hole inside the base 2.

[0042] Specifically, the laser rays emitted by the carbon dioxide laser generator 5 in the upper-end laser light source are irradiated onto the second reflector 9 after being coupled by the red light coupler 6, then pass through the light-near opening and are reflected onto the third reflector 10, and finally are irradiated into the suspension furnace body 1 through the hollow mounting seat at the upper part of the suspension furnace body 1 after being reflected by the fourth reflector 11.

[0043] In this embodiment, an equalizing disk is placed on the bracket 21, and a hopper for placing materials is installed at the central position of the equalizing disk.

[0044] Specifically, the laser rays emitted by the lower-end laser light source irradiate the materials in the hopper from bottom to top, and the laser rays emitted by the upper-end laser light source irradiate the materials in the hopper obliquely from two different angles, making the heating of the materials more uniform.

[0045] In this embodiment, an air flow installation hole is also provided on the side surface of the bracket 21, and compressed air flow can be blown upward from the holes inside the bracket 21 to blow out the processed materials from the hopper.

[0046] In this embodiment, an end cover is fixed to one end of the suspension furnace body 1 away from the base 2.

[0047] In this embodiment, the feeding assembly 3 includes a feeding pipe and a valve. The feeding pipe is fixed in the end cover, and the end of the feeding pipe extends to directly above the hopper, and the valve is fixed to the other end of the feeding pipe.

[0048] The working principle of the present utility model is as follows: When in use, first open the valve, and the external air flow sends the materials into the hopper through the feeding pipe. The carbon dioxide laser generators 5 in the upper-end laser light source and the carbon dioxide laser generators 5 in the lower-end laser light source are simultaneously turned on. The laser rays emitted by the carbon dioxide laser generators 5 in the lower-end laser light source are irradiated onto the first reflecting mirror 8 after being coupled by the red light coupler 6, and then enter the inside of the suspension furnace body 1 from the holes inside the base 2 after being reflected by the first reflecting mirror 8 to heat the bottom of the materials in the hopper. The laser rays emitted by the carbon dioxide laser generators 5 in the upper-end laser light source are irradiated onto the second reflecting mirror 9 after being coupled by the red light coupler 6, and then pass through the light inlet and are irradiated onto the third reflecting mirror 10 after being reflected by the second reflecting mirror 9, and then are irradiated onto the fourth reflecting mirror 11 after being reflected by the third reflecting mirror 10. The fourth reflecting mirror 11 reflects the laser and irradiates it onto the materials in the hopper from the hollow mounting seat at the upper part of the suspension furnace body 1. Since there are two upper-end laser light sources, cooperating with the lower-end laser light source, the three laser rays irradiate the materials from different angles, making the materials heat more uniformly, thereby improving the heating efficiency; the structure is simple, the operation is very convenient, and the labor intensity of workers is effectively reduced.
