Description
Technical Field
[0001] This utility model relates to the field of distribution boxes, specifically a high-temperature material waste heat recovery device. Background Technology
[0002] The steel industry is an important basic industry of the national economy. In the steel industry, high-temperature materials often contain a large amount of unused heat energy. This heat energy is often wasted in traditional processing. For example, the total amount of waste heat resources in pellets, sintered ore, and metallurgical slag is very large. Efficient recovery and utilization of waste heat is an important way to achieve energy saving and consumption reduction in subsequent processes.
[0003] In the existing field of high-temperature material waste heat recovery, common devices mainly rely on traditional heat exchange methods. For example, some simple waste heat recovery devices typically use a direct material-air flow path, allowing the high-temperature material to exchange heat with the air within a specific space.
[0004] However, these existing technologies have many problems. On the one hand, the heat exchange efficiency of traditional devices is low. Due to the limited contact surface between the high-temperature materials and the air in the recovery furnace, a large amount of waste heat cannot be fully recovered, resulting in serious energy waste. Furthermore, it takes more time and affects work efficiency. On the other hand, the structural design of some existing devices is not reasonable enough. High-temperature materials need to be fed into the recovery furnace from the top, which is more complicated to operate and can easily cause poor material flow, affecting production efficiency. It also increases the difficulty and cost of equipment maintenance. Utility Model Content

[0015] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0016] Please see the appendix Figure 1-4 This application provides the following technical solutions.
[0017] A high-temperature material waste heat recovery device includes a support 1, a waste heat recovery mechanism 2 is arranged in the middle of the support 1, a feeding mechanism 3 is arranged at the bottom of the waste heat recovery mechanism 2, and a fan 4 is fixedly connected to the bottom of the feeding mechanism 3; the waste heat recovery mechanism 2 includes a recovery furnace 21, a motor 22 is fixedly installed on the top of the recovery furnace 21, a rotating cylinder 24 is fixedly connected to the output end of the motor 22, a plurality of air outlets 27 are opened on the outer wall of the rotating cylinder 24, a heat outlet 23 is arranged on the outer wall of the recovery furnace 21, a cleaning scraper 26 is fixedly connected to the top of the rotating cylinder 24, and a stirring blade 25 is fixedly connected to the outer wall of the rotating cylinder 24; the feeding mechanism 3 includes a lifting pipe 31, the bottom of the lifting pipe 31 is fixedly connected to the recovery furnace 21, a rotating pipe 28 is fixedly connected to the bottom of the rotating cylinder 24, a material lifting blade 29 is fixedly connected to the outer wall of the rotating pipe 28, and the rotating pipe 28 and the material lifting blade 29 are inserted into the inside of the lifting pipe 31.
[0018] It should be noted that in actual use, the operator starts the motor 22, which drives the rotating drum 24 to rotate, which in turn drives the rotating tube 28 to rotate, which in turn drives the material lifting blade 29 to move. The high-temperature material requiring waste heat recovery is then fed into the feeding hopper 33 and enters the lifting tube 31 through the feeding port 32. The rotating material lifting blade 29 lifts the material into the recovery furnace 21. At the same time, the rotating drum 24 drives the cleaning scraper 26 to scrape inside the recovery furnace 21 to prevent impurities in the high-temperature material. When the material becomes stained and adheres to the inner wall of the recycling furnace 21, the operator starts the blower 4 to generate flowing air that enters the air injection pipe 39, then the rotating pipe 28, and finally the rotating cylinder 24. The material is then discharged through the air outlet 27. The rotating cylinder 24 drives the stirring blades 25 to rotate, causing the high-temperature material to be continuously turned over inside the recycling furnace 21, increasing its contact surface with the air. The flowing air exchanges heat with the turned high-temperature material, and the material is finally discharged into the energy conversion device for recycling through the heat outlet 23.
[0019] The bottom of the rotating pipe 28 is rotatably connected to an air injection pipe 39. A feeding port 32 is opened on one side of the lifting pipe 31. A feeding hopper 33 is fixedly connected to the side of the lifting pipe 31 with the feeding port 32. A limiting slide rail 35 is fixedly connected to the bottom of the feeding hopper 33. A sealing plate 36 is inserted into the inner wall of the limiting slide rail 35. A slot 37 is opened in the middle of the sealing plate 36. A discharge channel 34 is opened at the bottom of the lifting pipe 31. A fixing plate 38 is fixedly connected to the top of the discharge channel 34. The fixing plate 38 is inserted into the inner wall of the slot 37. The area of the sealing plate 36 and the slot 37 is larger than the area of the bottom opening of the lifting pipe 31.
[0020] It should be noted that after the high-temperature material waste heat recovery is completed, the operator pulls the sealing plate 36 to slide inside the limiting slide rail 35, pulls out the sealing plate 36, and makes the opening at the bottom of the lifting pipe 31 unobstructed. Then, the motor 22 is started to reverse, and the high-temperature material inside the recovery furnace 21 is transported into the lifting pipe 31 and discharged through the discharge channel 34. After the discharge is completed, the sealing plate 36 is inserted into the limiting slide rail 35 until the air injection pipe 39 and the fixing plate 38 are fully inserted into the inner wall of the slot 37, thus completing the sealing of the bottom opening of the lifting pipe 31.
[0021] In actual use, the operator starts the motor 22, which drives the rotating drum 24 to rotate. The rotating drum 24 drives the rotating pipe 28 to rotate, which in turn drives the material lifting blade 29. The high-temperature material requiring waste heat recovery is then fed into the feeding hopper 33 and enters the lifting pipe 31 through the feeding port 32. The rotating material lifting blade 29 lifts the material into the recovery furnace 21. At the same time, the rotating drum 24 drives the cleaning scraper 26 to scrape inside the recovery furnace 21, preventing impurities and stains from the high-temperature material from adhering to the inner wall of the recovery furnace 21. At this time, the operator starts the blower 4 to generate airflow, which enters the air injection pipe 39, then the rotating pipe 28, and finally the rotating drum 24. The air is then discharged through the air outlet 27. The rotating drum 24 drives the stirring blades 25 to rotate, causing the high-temperature material to be continuously turned over inside the recovery furnace 21, increasing its contact surface with air. The flowing air exchanges heat with the turned high-temperature material, and finally discharges into the energy conversion device for recovery through the heat outlet 23. After the high-temperature material waste heat recovery is completed, the operator pulls the sealing plate 36 to slide inside the limiting slide rail 35, pulls out the sealing plate 36, and makes the opening at the bottom of the lifting pipe 31 unobstructed. Then, the motor 22 is started to reverse, and the high-temperature material inside the recovery furnace 21 is transported into the lifting pipe 31 and discharged through the discharge channel 34. After the discharge is completed, the sealing plate 36 is inserted into the limiting slide rail 35 until the air injection pipe 39 and the fixing plate 38 are fully inserted into the inner wall of the slot 37, completing the sealing of the bottom opening of the lifting pipe 31.
