Description

Technical Field

[0001] This utility model relates to the field of blast furnace temperature recovery and utilization technology, and in particular to a device for recovering and utilizing blast furnace temperature of a certain type of iron. Background Technology

[0002] Blast furnace temperature recovery devices are important environmentally friendly and energy-saving equipment. They mainly utilize waste heat from boilers or other industrial equipment, recovering and converting this heat into reusable energy through heat exchange. By recovering waste heat, energy consumption can be significantly reduced and energy utilization efficiency improved. During iron ore processing, a large amount of waste heat is generated inside the high-temperature furnace. This waste heat is lost through the chimney along with the flue gas. However, current high-temperature furnace devices lack equipment for cleaning the heat transfer devices when recovering heat from the flue gas. This results in dirt accumulating on the surface of the heat transfer devices after prolonged operation, hindering effective heat recovery and leading to resource waste. Therefore, improvements are needed. Utility Model Content

[0053] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a blast furnace temperature recovery and utilization device for a type of iron ore.

[0054] A blast furnace temperature recovery and utilization device for a type of iron ore includes a chimney 1 and a fixed frame 2, wherein the fixed frame 2 has multiple components. The device further includes: a furnace temperature recovery mechanism, disposed on the fixed frame 2 and the chimney 1, for furnace temperature recovery; and a cleaning mechanism, disposed on the chimney 1 and the furnace temperature recovery mechanism, for cleaning components within the furnace temperature recovery mechanism. The cleaning mechanism includes: a mounting plate 3, disposed on and fixedly connected to the chimney 1; multiple cleaning scrapers 4, disposed on and fixedly connected to the mounting plate 3; a cleaning plate 5, disposed on and fixedly connected to the mounting plate 3; a support frame 6, disposed on and fixedly connected to the chimney 1; a discharge trough 11, disposed on the support frame 6, for discharging dirt; and two cylinders 7, disposed between the support frame 6 and the mounting plate 3, for providing power to move the mounting plate 3.

[0055] With this configuration, the cleaning scraper 4 can clean the surface of the heat-conducting plate 9, ensuring that the heat-conducting plate 9 can absorb heat over a large area; the cleaning plate 5 is used to catch the dirt scraped off by the cleaning scraper 4, and the cleaning plate 5 is longer than the cleaning scraper 4, so that the cleaning plate 5 can effectively catch the dirt.

[0056] refer to Figure 1 and Figure 2 In a preferred embodiment, the furnace temperature recovery mechanism includes: a heat conduction device disposed inside the chimney 1 for furnace temperature recovery; an acceleration device disposed on the fixed frame 2 for accelerating the flow of hot gas; and a utilization device disposed on the fixed frame 2 for utilizing the furnace temperature.

[0057] refer to Figure 3 and Figure 4 In a preferred embodiment, the heat conduction device includes: a heat dissipation plate 8 disposed inside the chimney 1 and fixedly connected to the chimney 1; multiple heat conduction plates 9 disposed on the heat dissipation plate 8 and fixedly connected to the heat dissipation plate 8; and a sealing shell 10 disposed on the chimney 1 and fixedly connected to the chimney 1.

[0058] refer to Figure 2In a preferred embodiment, the acceleration device includes: two fixing plates 12, which are disposed within the sealing shell 10 and fixedly connected to the sealing shell 10; a heat insulation shell 13, which is disposed on the fixing plates 12 and fixedly connected to the fixing plates 12; a drive motor 14, which is disposed within the heat insulation shell 13 and fixedly connected to the heat insulation shell 13; and a fan blade 15, which is disposed at the output end of the drive motor 14 and fixedly connected to the output end of the drive motor 14.

[0059] refer to Figure 1 and Figure 5 In a preferred embodiment, the utilization device includes: a utilization part disposed on the fixing frame 2 for furnace temperature utilization; and an external connection part disposed on the utilization part for connecting external components.

[0060] refer to Figure 2 and Figure 5 In a preferred embodiment, the utilization unit includes: a working box 16, disposed on the sealing shell 10 and fixedly connected to the sealing shell 10; two heat conduction pipes 17, disposed inside the working box 16 and fixedly connected to the working box 16; two exhaust valves 18, disposed on the working box 16 and fixedly connected to the working box 16; and a temperature control valve 19, disposed on the working box 16 and fixedly connected to the working box 16.

[0061] refer to Figure 1 In a preferred embodiment, the external part includes: a first water pump 20, which is disposed on the fixed frame 2 and fixedly connected to the fixed frame 2; and a second water pump 21, which is disposed on the fixed frame 2 and fixedly connected to the fixed frame 2.

[0062] With this configuration, the heat pipe 17 is coiled inside the working chamber 16, allowing the hot air to effectively heat the water and making full use of the heat. The drive motor 14, in conjunction with the fan blades 15, accelerates the flow of the hot air entering the device. The working chamber 16 is provided with slots for connecting the first water pump 20 and the second water pump 21, with the slot for the first water pump 20 being smaller than the slot for the second water pump 21. This is to ensure that when the temperature control valve 19 is opened, the inflow rate is greater than the outflow rate, allowing most of the heated water to leave the working chamber 16, while also ensuring that the heat in the heating pipe can be absorbed by the newly entered water.

[0063] This device, by incorporating a furnace temperature recovery mechanism, effectively recovers and utilizes the furnace temperature within a high-temperature furnace. It also accelerates heat flow, thereby speeding up heat recovery and facilitating resource reuse. Furthermore, the device includes a cleaning mechanism that automatically cleans the heat-conducting plates 9 used for heat recovery within the furnace temperature recovery mechanism after the furnace temperature has been recovered, ensuring the cleanliness of the heat-conducting plates 9 and enabling them to effectively recover heat, thus maximizing resource utilization.

[0064] Working Principle: When using this device, the first water pump 20 is started to fill the working chamber 16 with water, and the exhaust valve 18 is opened simultaneously. Then, as heat and flue gas enter the chimney 1, the high heat in the flue gas causes the heat-conducting plate 9 to contact the heat dissipation plate 8. The heat dissipation plate 8 discharges the hot air into the sealed shell 10. The drive motor 14 then drives the fan blades 15 to rotate, allowing the hot air to quickly enter the heat-conducting pipe 17. The hot air heats the water in the working chamber 16 along the heat-conducting pipe 17. When the water temperature reaches a certain level, the temperature control valve 19 automatically opens, and simultaneously, the first water pump 20 and the second water pump 21 start synchronously, heating the working chamber. Hot water in the working chamber 16 is pumped into the hot water storage tank. At the same time, the first water pump 20 adds water to the working chamber 16. When the water temperature is too low, the low temperature control valve 19 closes and the second water pump 21 closes simultaneously. The first water pump 20 continues to add water until the working chamber 16 is full. The first water pump 20 then stops working. After the work is completed, the cylinder 7 can be started. The cylinder 7 drives the mounting plate 3 and the cleaning plate 5 to move closer to the heat dissipation plate 8. When the mounting plate 3 moves, the cleaning scraper 4 cleans the heat conduction plate 9, removing the dirt from the surface of the heat conduction plate 9 to ensure that the heat conduction plate 9 can absorb heat to its maximum capacity.

[0065] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
