[0002] A three-stage temperature-controlled roasting furnace is a furnace with three independent temperature zones, each of which can be independently controlled to meet the different temperature requirements of different roasting stages. This type of furnace is commonly used in industrial production, particularly in materials science and chemical synthesis, where precise temperature control is required to ensure the quality and efficiency of the roasting process.
[0003] The existing three-stage temperature-controlled roasting furnace mainly uses three independent temperature zones to roast materials in stages by controlling different temperatures. However, the heating and heat preservation effects are poor at the beginning and during roasting, requiring a large amount of fuel to be continuously burned to maintain the current temperature, which is wasteful of fuel. In addition, it is impossible to cool the roasted material quickly, and it is necessary to wait for the material to cool down before it can be taken out, which delays production efficiency. Therefore, it is necessary to solve the problem that the existing temperature-controlled roasting furnace has a slow heating rate and cannot quickly cool the roasted material, which affects the working efficiency.

[0025] This utility model discloses a three-stage temperature-controlled roasting furnace.
[0026] This utility model provides, for example Figure 1-5The three-stage temperature-controlled roasting furnace shown includes a support platform 1. Three support columns 2 are fixedly connected to the top of the support platform 1, and are respectively fixedly connected to a first-stage furnace 3, a second-stage furnace 4, and a third-stage furnace 5.

The furnace is equipped with a cooling chamber device 15, and utilizes a first-stage furnace 3, a second-stage furnace 4, and a third-stage furnace 5 to meet different stages of roasting. A temperature control console 14 controls the system, and an oxygen-supporting spray plate 8 provides oxygen to the combustion device 7 for combustion. A pressure relief valve 9 releases excess pressure, and an insulation jacket 10 improves the heating and insulation efficiency of the furnace body 6. Control valves 11 isolate each furnace body 6 in sections and facilitate the transport of materials from the previous stage. A feed hopper 12 allows for easy material loading into the furnace body 6, and an electric valve 13 seals the feed hopper 12 to save fuel resources. The cooling chamber device 15 rapidly cools the processed material, improving work efficiency. This addresses the problem of existing temperature-controlled roasting furnaces having slow heating rates and the inability to quickly cool roasted materials, thus affecting work efficiency.
[0027] In order to roast the materials in furnace body 6, such as Figure 1 , 2 As shown in Figures 3 and 5, each combustion device 7 includes a gas chamber 16, an ignition device 17, and burners 18. The ignition device 17 is fixedly connected to one end of the gas chamber 16, and nine burners 18 are fixedly connected to the bottom of the gas chamber 16. Gas is introduced into the gas chamber 16 through a gas pipeline connected to the input end, ignited by the ignition device 17, and finally flames are emitted from the nine burners 18 at the bottom to roast the material.
[0028] In order to provide oxygen to combustion device 7 for combustion support, such as Figure 1-3As shown, each oxygen-supporting spray plate 8 is a hollow plate with multiple spray holes 19 at the bottom. Each oxygen-supporting spray plate 8 is fixedly connected to an oxygen connection pipe 20 at the top.

By using the cooling jacket 23, which is a hollow plate and has water inlet 25 and water outlet 26 fixedly connected to both ends of the side wall, a water source is connected through the water inlet 25 and water outlet 26. The heat is exchanged through the water source to cool the material in the cavity.

During use, the material is fed into the material hopper 12 through the feeding device. The material first enters the first stage furnace 3, the second stage furnace 4 and the third stage furnace 5 in sequence and is roasted by the combustion device 7. The temperature control console 14 controls the first stage furnace 3, the second stage furnace 4 and the third stage furnace 5 to maintain the corresponding temperature. Finally, the processed material is discharged into the cooling chamber device 15, and the heat of the material is removed by the water source in the cooling jacket 23 to cool the material in the chamber.
