[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1 - Figure 6This utility model provides an embodiment of a multi-temperature zone intelligent temperature control device for a roasting furnace, including a base plate 1, a waste heat recovery box 21, and a multi-temperature zone combustion assembly. A roasting furnace body 4 is fixedly connected to the top of the base plate 1. A feed inlet 5 is fixedly connected to the left end of the roasting furnace body 4. The roasting furnace body 4 is internally equipped with a multi-temperature zone combustion assembly to facilitate complete combustion of materials. The waste heat recovery box 21 is fixedly connected to the top right end of the base plate 1. A connecting pipe 22 is fixedly connected between the waste heat recovery box 21 and the roasting furnace body 4. An activated carbon purification plate 27 is installed inside the waste heat recovery box 21. A hot water tank 212 is fixedly connected to the top of the waste heat recovery box 21. A water inlet pipe 213 is fixedly connected to the top of the hot water tank 212. The bottom right end of the hot water tank 212 is fixedly connected to the... A water outlet pipe 214 is fixedly connected to the waste heat recovery box 21, and a first conveying pipe 215 is fixedly connected between the hot water tank 212 and the waste heat recovery box 21. A second conveying pipe 216 is fixedly connected to the top of the hot water tank 212 to facilitate the discharge of gas. A serpentine heat exchange tube 217 is fixedly connected between the second conveying pipe 216 and the first conveying pipe 215. Two activated carbon purification plates 27 can adsorb the dust particles mixed in the flue gas, thus filtering the flue gas. The filtered flue gas will enter the serpentine heat exchange tube 217 through the first conveying pipe 215. The flue gas can heat the water in the hot water tank 212 through the serpentine heat exchange tube 217, so that the heat is utilized. Then the flue gas can be discharged through the second conveying pipe 216, thereby reducing environmental pollution and preventing air pollution. To reduce the deterioration of quality and minimize harm to the surrounding ecosystem and human health, thus improving its environmental friendliness, the multi-temperature zone combustion assembly uses temperature sensors 37 (model WZPB-230) on the first temperature zone 32, second temperature zone 33, and third temperature zone 34. The intelligent temperature control device body 31, temperature sensors 37, and burners 36 are common technologies in this field and will not be described in detail here. They detect the internal temperature and then feed it back to the intelligent temperature control device body 31. The intelligent temperature control device body 31 controls the burners 36 on each temperature zone, allowing each zone to have its own independently set temperature curve, improving the temperature uniformity and stability of the roasting process. The insulation layer 35 further enhances the temperature distribution between each temperature zone. To effectively isolate the flue gas from the bottom plate 1 and improve combustion efficiency, two activated carbon purification plates 27 are provided, arranged sequentially from top to bottom inside the waste heat recovery box 21. These plates filter the flue gas emitted from the bottom plate 1, reducing external pollution. A limiting strip 26 is fixedly connected inside the waste heat recovery box 21, with the activated carbon purification plates 27 positioned inside the limiting strip 26. A mounting plate 24 is fixedly connected to the front end of the activated carbon purification plate 27, and a sealing gasket 28 is fixedly connected to the rear end of the mounting plate 24. The activated carbon purification plate 27 is positioned inside the sealing gasket 28. A handle 25 is fixedly connected to the front end of the mounting plate 24, and a fixing frame 23 is fixedly connected to the front end of the bottom plate 1. A locking block 218 is slidably connected inside the fixing frame 23.The locking block 218 is snapped into the interior of the mounting plate 24. A smooth rod 29 is fixedly connected to the top of the locking block 218. The smooth rod 29 is slidably connected to the interior of the fixing frame 23. A lever 211 is fixedly connected to the smooth rod 29. A spring 210 is fixedly connected between the locking block 218 and the fixing frame 23, allowing it to adsorb dust particles mixed in the flue gas through two activated carbon purification plates 27, thus filtering the flue gas. The filtered flue gas enters the serpentine heat exchange tube 217 through the first conveying pipe 215. The flue gas can heat the water in the hot water tank 212 through the serpentine heat exchange tube 217, making the heat utilization possible. Subsequently, the flue gas can be discharged through the second conveying pipe 216, reducing environmental pollution, preventing air quality deterioration, and minimizing harm to the surrounding ecosystem and human health. To improve environmental friendliness, the mounting plate 24 has a corresponding groove for the locking block 218. The locking block 218 engages with the groove in the mounting plate 24, allowing the activated carbon purification plate 27 to be installed. This improves the ease of installation and the practicality of the device. Similarly, the waste heat recovery box 21 has a corresponding groove for the activated carbon purification plate 27. The activated carbon purification plate 27 is placed in the groove of the waste heat recovery box 21. During installation, the activated carbon purification plate 27 is aligned with the groove in the base plate 1 and inserted into the inner side of the limiting strip 26. The locking block 218 then engages with the groove in the mounting plate 24, completing the installation of the activated carbon purification plate 27 and improving ease of installation.

[0024] Please see Figure 1 , Figure 6In this embodiment, the multi-temperature zone combustion assembly includes an intelligent temperature control device body 31, which is fixedly connected to the top of the base plate 1. The roasting furnace body 4 is provided with a first temperature zone 32, a second temperature zone 33, and a third temperature zone 34. A heat insulation layer 35 is provided between the first temperature zone 32, the second temperature zone 33, and the third temperature zone 34. Temperature sensors 37 are fixedly connected to each of the first temperature zone 32, the second temperature zone 33, and the third temperature zone 34, and are electrically connected to the intelligent temperature control device body 31. Burners 36 are fixedly connected to the outer sides of each of the first temperature zone 32, the second temperature zone 33, and the third temperature zone 34, and are electrically connected to the intelligent temperature control device body 31. The multi-temperature zone combustion assembly utilizes the temperature sensors on the first temperature zone 32, the second temperature zone 33, and the third temperature zone 34. Temperature sensor 37 detects its internal temperature and sends the feedback to the intelligent temperature control device 31. The intelligent temperature control device 31 controls the burners 36 in each temperature zone, allowing each zone to have its own temperature curve set, thus improving the temperature uniformity and stability of the roasting process. The insulation layer 35 effectively isolates the temperature between each temperature zone, improving combustion efficiency. Three sets of temperature sensors 37 are arranged from left to right on the first temperature zone 32, the second temperature zone 33, and the third temperature zone 34. Similarly, three sets of burners 36 are arranged from left to right on the first temperature zone 32, the second temperature zone 33, and the third temperature zone 34, allowing each zone to have its own temperature curve set, thus improving the temperature uniformity and stability of the roasting process.

[0025] During operation, the internal temperature is detected by temperature sensors 37 on the first temperature zone 32, the second temperature zone 33, and the third temperature zone 34, and then fed back to the intelligent temperature control device body 31. The intelligent temperature control device body 31 controls the burners 36 on each temperature zone, allowing each temperature zone to have its own temperature curve set, thereby improving the temperature uniformity and stability of the roasting process. The heat insulation layer 35 effectively isolates the temperature between each temperature zone, improving combustion efficiency. Then, the flue gas generated inside the roasting furnace body 4 passes through... The connecting pipe 22 enters the interior of the waste heat recovery box 21. Two activated carbon purification plates 27 adsorb dust particles mixed in the flue gas, filtering it. The filtered flue gas then enters the serpentine heat exchange tube 217 through the first conveying pipe 215. The flue gas heats the water in the hot water tank 212 through the serpentine heat exchange tube 217, utilizing the heat. The flue gas is then discharged through the second conveying pipe 216. Water to be heated is added to the hot water tank 212 through the inlet pipe 213, and water can be discharged through the outlet pipe 214. The heated water inside the hot water tank 212 is discharged. When it is necessary to disassemble, replace, or clean the activated carbon purification plate 27, the lever 211 is pushed upwards, causing it to move the locking block 218 away from the groove of the mounting plate 24 via the smooth rod 29. This allows the activated carbon purification plate 27 to be pulled out of the waste heat recovery box 21 via the handle 25, making it easy to clean and replace. When installing the activated carbon purification plate 27, it is aligned with the groove of the base plate 1 and inserted into the inner side of the limiting strip 26. When the activated carbon purification plate 27 and the fixed frame 23 come into contact with the arc end of the locking block 218, the locking block 218 moves upward, compressing the spring 210. When the sealing gasket 28 comes into contact with the waste heat recovery box 21, the spring 210 uses its own elasticity to move the locking block 218 downward, locking the locking block 218 into the groove of the fixed frame 23, thus installing and fixing the activated carbon purification plate 27. The sealing gasket 28 improves the sealing performance of the waste heat recovery box 21, thereby improving the practicality of the device.

[0026] Through the above steps, the two activated carbon purification plates 27 can adsorb the dust particles mixed in the flue gas, thus filtering the flue gas. The filtered flue gas will enter the serpentine heat exchange tube 217 through the first conveying pipe 215. The flue gas can heat the water in the hot water tank 212 through the serpentine heat exchange tube 217, so that the heat is utilized. Then the flue gas can be discharged through the second conveying pipe 216, thereby reducing environmental pollution and preventing air quality deterioration, thus solving the problem of significant environmental pollution and exacerbating air quality deterioration.
