Description

Technical Field

[0001] This utility model relates to the field of environmental protection equipment technology, specifically to a high-efficiency and environmentally friendly arched dust collection hood. Background Technology

[0002] During the tapping process at the blast furnace tapping area, a large amount of high-temperature, toxic, and harmful fumes are generated. These fumes not only severely pollute the workshop and surrounding environment and affect the service life of equipment, but also directly endanger the health of on-site operators. Therefore, the effective capture and treatment of fumes generated at the tapping point is a key link for steel enterprises to achieve green and safe production.

[0003] However, existing technologies present certain technical challenges in dust removal at the tapping spout of steel mills. For example: 1. When the skimmer at the tapping spout opens, a large amount of concentrated dust is generated. If this dust cannot be collected promptly, it can easily overflow, polluting the surrounding environment and harming the health of on-site workers; 2. During the tapping process, the dust temperature is high. Failure to cool the dust in a timely manner will shorten the lifespan of the dust collector hood and dust collection system, undoubtedly increasing production costs for steel mills. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a highly efficient and environmentally friendly arched dust hood that not only facilitates the handling of smoke and dust during iron tapping at the blast furnace tapping area but also makes it easy for workers to weld and fix the dust collection pipe to the top plate.

[0005] This utility model is achieved through the following technical solution: a high-efficiency and environmentally friendly arched dust collection hood is provided, including a top plate and vertical plates fixed to the left and right ends of the top plate by arc plates. The top plate has a dust collection hole, and the inner wall of the dust collection hole has a through groove that is closed in the circumferential direction. The through groove extends vertically upward, and a number of elastic plates that are equidistantly distributed in the circumferential direction and inclined downward are fixed to the bottom of the through groove.

[0006] In use, this utility model features a top plate and vertical plates fixed to the left and right ends of the top plate via arc-shaped plates. A dust-collecting hole is located at the top of the top plate, and a circumferentially closed through-groove is formed on the inner wall of the dust-collecting hole. The through-groove extends vertically upwards, and several circumferentially equidistant and downwardly inclined elastic plates are fixed to the bottom of the through-groove. During use, the device is moved via a control device to position the blast furnace tapping hole inside the top plate, arc-shaped plate, and vertical plates. Then, the lower end of the dust-collecting pipe is inserted into the dust-collecting hole, and the lower end face of the dust-collecting pipe abuts against the lower side wall of the through-groove. The outer circumference of the dust collection pipe will contact several elastic plates fixed to the bottom of the through slot, thereby assisting in the coaxial setting of the dust collection pipe and the dust collection hole. Then, the dust collection pipe is welded and fixed to the top plate using tools. When the blast furnace tapping area taps iron, the generated dust will rise and move along the inner wall of the arc plate to the inner wall of the top plate. Then, the dust will be discharged from the inner wall of the top plate through the dust collection hole by the suction of the dust collection pipe. This not only makes it convenient for the staff to deal with the dust when the blast furnace tapping area taps iron, but also makes it easy for the staff to weld and fix the dust collection pipe to the top plate.

[0007] Preferably, several support rods distributed laterally along the front-to-back direction are welded and fixed to the outer walls of the top plate, the arc-shaped plate, and the vertical plate. A crossbar, fixed to the inner sidewall of two adjacent support rods, is also attached and fixed to the outer walls of the top plate, the arc-shaped plate, and the vertical plate. By welding and fixing several support rods distributed laterally along the front-to-back direction to the outer walls of the top plate, the arc-shaped plate, and the vertical plate, and by attaching and fixing crossbars to the outer walls of the top plate, the arc-shaped plate, and the vertical plate, the stability of the device during use can be improved.

[0008] Preferably, the top plate includes a connecting plate fixedly connected to the end of the curved plate away from the vertical plate. The end of the connecting plate away from the curved plate is inclined upwards, and the two connecting plates are fixedly connected at their ends away from the curved plate. The inclined connecting plate allows smoke and dust to be easily discharged from the inner wall of the top plate through suction holes via the suction force of the suction pipe.

[0009] Preferably, the suction hole is aligned vertically with the top plate. By aligning the suction hole with the top plate vertically, it is easier for smoke and dust to be discharged from the inner wall of the top plate through the suction hole using the suction force of the suction pipe.

[0010] Preferably, the vertical plate, the arc-shaped plate, and the connecting plate are configured as an integral structure. By configuring the vertical plate, the arc-shaped plate, and the connecting plate as an integral structure, the stability of the device during use can be improved, and the escape of flue gas from the gaps between the vertical plate and the arc-shaped plate, between the arc-shaped plate and the connecting plate, and between the two connecting plates can be prevented during use.

[0011] Preferably, the inner walls of the upright plate, the arc plate, and the connecting plate are provided with a high-temperature resistant coating. By providing a high-temperature resistant coating on the inner walls of the upright plate, the arc plate, and the connecting plate, the heat received by the device can be reduced, thereby reducing the deformation of the device and improving its service life.

[0012] The beneficial effects of this utility model are as follows: A top plate and vertical plates fixed to the left and right ends of the top plate via arc-shaped plates are provided. A dust-collecting hole is opened at the top of the top plate, and a circumferentially closed through-groove is opened on the inner wall of the dust-collecting hole. The through-groove extends vertically upwards, and several elastic plates, evenly distributed circumferentially and inclined downwards, are fixed to the bottom of the through-groove. During use, the device is moved by a control device so that the iron tapping opening of the blast furnace iron tapping area is located inside the top plate, arc-shaped plate, and vertical plates. Then, the lower end of the dust-collecting pipe is inserted into the dust-collecting hole, and the lower end face of the dust-collecting pipe abuts against the lower side wall of the through-groove. During this process… The outer circumference of the dust collection pipe will contact several elastic plates fixed to the bottom of the through slot, thereby assisting in the coaxial setting of the dust collection pipe and the dust collection hole. Then, the dust collection pipe is welded and fixed to the top plate using tools. When the blast furnace tapping area taps iron, the generated dust will rise and move along the inner wall of the arc plate to the inner wall of the top plate. Then, the dust will be discharged from the inner wall of the top plate through the dust collection hole by the suction of the dust collection pipe. This not only makes it convenient for the staff to deal with the dust when the blast furnace tapping area taps iron, but also makes it easy for the staff to weld and fix the dust collection pipe to the top plate.

Detailed Implementation

[0014] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0015] like Figures 1-3The high-efficiency and environmentally friendly arched dust cover of this utility model includes a top plate 7 and vertical plates 2 fixed to the left and right ends of the top plate 7 by arc plates 1. The top plate 7 has a dust suction hole 8 at the top. The inner wall of the dust suction hole 8 has a through groove 10 that is closed in the circumferential direction. The through groove 10 extends vertically upward. The bottom of the through groove 10 is fixed with a number of elastic plates 9 that are equidistantly distributed in the circumferential direction and inclined downward.

[0016] Several support rods 4, distributed laterally along the front-to-back direction, are welded and fixed to the outer walls of the top plate 7, the arc-shaped plate 1, and the vertical plate 2. Horizontal bars 3, fixed to the inner walls of adjacent support rods 4, are also attached and fixed to the outer walls of the top plate 7, the arc-shaped plate 1, and the vertical plate 2. The support rods 4 and horizontal bars 3 enhance the stability of the device during use. The top plate 7 includes a connecting plate fixed to the end of the arc-shaped plate 1 away from the vertical plate 2. The end of the connecting plate away from the arc-shaped plate 1 is inclined upwards, and the two connecting plates are fixedly connected at their ends away from the arc-shaped plate 1. The inclined connecting plate facilitates the suction of dust through the suction pipe, allowing it to be discharged from the inner wall of the top plate 7 through the suction hole 8. By aligning the suction hole 8 with the top plate 7 vertically, dust can be easily discharged from the inner wall of the top plate 7 through the suction hole 8. By integrating the vertical plate 2, the arc-shaped plate 1, and the connecting plate into a single structure, the stability of the device during operation is improved, preventing flue gas from escaping from the gaps between the vertical plate 2 and the arc-shaped plate 1, between the arc-shaped plate 1 and the connecting plate, and between the two connecting plates. A high-temperature resistant coating 6 is applied to the inner walls of the vertical plate 2, the arc-shaped plate 1, and the connecting plate. This coating reduces the heat absorbed by the device, thereby minimizing deformation and extending its service life. A sealing door 5 is installed on the outer wall of one of the vertical plates 2, facilitating repairs to the blast furnace tapping area if the tapping spout malfunctions and cannot be opened.

[0017] Combined with appendix Figure 1-3 As can be seen, the method of using this utility model is as follows: First, the blast furnace tapping area is moved by the control device so that the tapping port is located inside the top plate 7, the arc plate 1 and the vertical plate 2. Then, the lower end of the dust suction pipe is inserted into the dust suction hole 8 and the lower end face of the dust suction pipe abuts against the lower side wall of the through groove 10. During this process, the outer circumferential surface of the dust suction pipe will contact several elastic plates 9 fixed to the bottom of the through groove 10, thereby assisting the dust suction pipe and the dust suction hole 8 to be coaxially set. Then, the dust suction pipe is welded and fixed together with the top plate 7 by using tools. When the blast furnace tapping area taps iron, the generated smoke and dust will rise and move along the high temperature resistant coating 6 on the inner side wall of the arc plate 1 to the high temperature resistant coating 6 on the inner side wall of the connecting plate. Then, the suction force of the dust suction pipe will make the smoke and dust discharged from the high temperature resistant coating 6 on the inner side wall of the connecting plate through the dust suction hole 8.
