Description

Technical Field

[0001] This application relates to the technical field of synthesis furnaces, and in particular to a high-temperature solid-phase synthesis furnace for preparing long-afterglow luminescent materials. Background Art

[0002] With the wide application of long-afterglow luminescent materials in many fields such as road traffic, urban and rural construction, fire safety, and building decoration, their preparation technologies and production equipment have attracted great attention. Long-afterglow luminescent materials are mainly prepared by high-temperature solid-phase synthesis. During high-temperature solid-phase reaction, the raw materials need to be sintered in a mixed reducing atmosphere formed by hydrogen and nitrogen to complete the synthesis of long-afterglow luminescent materials.

[0003] For example, the Chinese utility model patent with the application number CN201821838532.2 discloses a high-temperature solid-phase synthesis furnace for preparing long-afterglow luminescent materials. This solution includes a furnace body, and a furnace chamber and an auxiliary atmosphere mixing chamber are arranged in the furnace body; the auxiliary atmosphere mixing chamber can be communicated with the outside through a first air inlet pipe and a second air inlet pipe. A first air inlet valve and a first flow meter are arranged on the first air inlet pipe, and a second air inlet valve and a second flow meter are arranged on the second air inlet pipe. The auxiliary atmosphere mixing chamber is connected to the furnace chamber through a supply pipe; an air outlet pipe that can be communicated with the outside is arranged at the top of the furnace chamber, and an air outlet valve is arranged on the air outlet pipe. This design can control the gas mixing ratio and make the gas mixing more uniform.

[0004] The foregoing solution still has inconveniences. The foregoing solution increases the mixing efficiency by adding a blower at the bottom of the synthesis furnace. However, when the blower is working, it will suck in external air, and the external air contains more impurities without filtration treatment, which will be brought into the synthesis furnace together, resulting in serious dust accumulation in the synthesis furnace and being inconvenient for long-term use.

[0022] The following further describes the present application in conjunction with the attached Figures 1 - 5 drawings.

[0023] An embodiment of the present application discloses a high-temperature solid-phase synthesis furnace for preparing long-afterglow luminescent materials. Referring to Figures 1 - 5 , a high-temperature solid-phase synthesis furnace for preparing long-afterglow luminescent materials includes a main body 1 of the synthesis furnace and a main body 16 of the fan. A hydrogen pipe 4 and a nitrogen pipe 5 are respectively fixedly connected to the bottom end of the main body 1 of the synthesis furnace. A sealing cover 2 is fixed on the top of the main body 1 of the synthesis furnace, and an exhaust pipe 3 is connected to the sealing cover 2; it further includes a filtering mechanism. A pair of connecting square pipes 6 are fixed to the bottom of the main body 1 of the synthesis furnace. A pair of air inlets 12 are provided on the bottom surface of the main body 1 of the synthesis furnace. The two connecting square pipes 6 respectively cover the outside of the air inlets 12. The filtering mechanism is installed on the connecting square pipes 6 for filtering air impurities. The two main bodies 16 of the fan are respectively fixed on the connecting square pipes 6, and the main body 16 of the fan faces the air inlets 12. The filtering mechanism includes a dust filter screen 14. A filtering square pipe 7 is fixed on the connecting square pipe 6. A limiting frame 17 is fixed on the inner wall of the filtering square pipe 7. The dust filter screen 14 is embedded in the filtering square pipe 7 and is connected to the limiting frame 17.

[0024] During use, hydrogen and nitrogen are respectively introduced into the hydrogen pipe 4 and the nitrogen pipe 5, and then the main body 16 of the fan is started. The air extracted by the main body 16 of the fan will be filtered by the dust filter screen 14. By providing the filtering square pipe 7 and the dust filter screen 14, the air extracted by the main body 16 of the fan can be filtered, thereby reducing impurities from entering the main body 1 of the synthesis furnace and further improving the mixing purity of the synthesized substances in the main body 1 of the synthesis furnace.

[0025] In this embodiment, as Figure 3 and Figure 5 shown, a limiting plate 15 is rotatably installed on the filtering square pipe 7. There is a sliding damping between the limiting plate 15 and its connected rotating shaft. The limiting plate 15 is in contact with the dust filter screen 14. The sliding damping can keep the limiting plate 15 stable, so that the dust filter screen 14 is stably installed and has a good limiting effect.

[0026] In this embodiment, as Figures 2 to 4As shown in the figure, a rotating seat 13 is fixed on the inner bottom surface of the synthesis furnace body 1. A hemispherical circular groove is formed at the top of the rotating seat 13. The device further includes a rotating rod 10.

The fan blades 11 are located above the air inlet 12. When the two fan bodies 16 operate, the wind they blow will blow against the fan blades 11. After the fan blades 11 receive the thrust, they will drive the rotating rod 10 to rotate, so that the plurality of fan blades 11 disperse the hydrogen and nitrogen introduced inside, thereby facilitating the improvement of their mixing efficiency.

[0027] The implementation principle of a high-temperature solid-phase synthesis furnace for preparing long-afterglow luminescent materials in an embodiment of the present application is as follows: During use, hydrogen and nitrogen are respectively introduced from the hydrogen pipe 4 and the nitrogen pipe 5, and then the fan body 16 is started. The air extracted by the fan body 16 will be filtered by the dust filter net 14. When the two fan bodies 16 operate, the wind they blow will blow against the fan blades 11. After the fan blades 11 receive the thrust, they will drive the rotating rod 10 to rotate, so that the plurality of fan blades 11 disperse the hydrogen and nitrogen introduced inside. By providing the filtering square pipe 7 and the dust filter net 14, the air extracted by the fan body 16 can be filtered, thereby reducing impurities from entering the synthesis furnace body 1 and further improving the mixing purity of the synthesis product inside the synthesis furnace body 1.
