Description

Technical Field

[0001] The invention relates to the technical field of tapping assistance for an ore-fired furnace, in particular to an iron tapping hole device for an ore-fired furnace. Background Art

[0002] Submerged arc furnace is also called electric arc furnace or electric resistance furnace. It is mainly used for reducing smelting ore, carbonaceous reducing agent and solvent and other raw materials. It mainly produces ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, silicon manganese alloy and other ferroalloys, which are important industrial raw materials in the metallurgical industry and chemical raw materials such as calcium carbide.

[0003] At present, the existing iron outlet device for the ore-heating furnace has the following shortcomings in use: usually after the smelting of the ore-heating furnace is completed, it is necessary to use a blasting machine to blast the iron outlet and then open it, and release the molten iron through the iron outlet, usually it is necessary to use an iron outlet trough or an iron outlet machine for cooperation. During this operation, the molten iron at the iron outlet opened by the blasting machine is instantly and quickly ejected, and the range of the ejection is uncontrollable, resulting in molten iron splashing everywhere. Although most of it enters the iron trough, a lot of it is ejected around the iron trough, which is easy to damage the surrounding equipment and cause waste of molten iron. The molten iron ejected around is not easy to clean after cooling, and there will be residual molten iron and other substances adsorbed at the iron outlet. After the molten iron is discharged from the iron outlet, the residual temperature is too high, and the workers need to wear heat-insulating gloves and use shovels or other tools to clean it under the high temperature. The cleaning effect is not ideal and is very dangerous. After cooling, the molten iron is adsorbed on the inner wall of the iron outlet and is not easy to clean, resulting in blockage of the iron outlet, which will invisibly increase the workload of the workers and reduce the efficiency and quality of the overall iron-discharging of the ore-heating furnace.

[0004] Therefore, those skilled in the art provide a tap hole device for an electric arc furnace to solve the problems raised in the above background technology. Summary of the invention

After the molten iron is discharged from the taphole, the residual temperature is too high, and the workers need to wear heat-insulating gloves and use shovels or other tools to clean it under the high temperature. The cleaning effect is not ideal and is very dangerous.

DETAILED DESCRIPTION

[0031] The embodiment of the present invention provides a taphole device for an ore-heating furnace, which solves the following problems: in the use of the existing taphole device for an ore-heating furnace, after the ore-heating furnace is smelted, it is usually necessary to use a blasting machine to blast the taphole and then open it, and release molten iron through the taphole, which usually requires the use of a taphole trough or a taphole machine for cooperation. During this operation, the molten iron at the taphole opened by the blasting machine is instantly and rapidly ejected, and the range of the ejection is uncontrollable, resulting in molten iron splashing everywhere. Although most of it enters the iron trough, a lot of it is ejected around the iron trough, which is easy to damage surrounding equipment and cause waste of molten iron. The molten iron ejected around is not easy to clean after cooling, and there is residual molten iron and other substances adsorbed at the taphole. After the molten iron is discharged from the taphole, the residual temperature is too high, and the workers need to wear heat-insulating gloves and use shovels or other tools to clean it under the high temperature. The cleaning effect is not ideal and is very dangerous. After cooling, the molten iron is adsorbed on the inner wall of the taphole and is not easy to clean, resulting in blockage of the taphole, which invisibly increases the workload of the workers and reduces the efficiency and quality of the overall ore-heating furnace.

[0032] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

The flow assembly 551 includes two mounting frames 30 fixedly connected to the inner side of the supporting top frame 1, and a main blocking bridge 29 is rotatably connected between the two mounting frames 30. A tooth bridge 26 is fixedly connected to the upper surface of the main blocking bridge 29. The inner side of the supporting top frame 1 is rotatably connected to a gear transmission assembly 552 used in conjunction with the tooth bridge 26. The gear transmission assembly 552 includes a rotating shaft 24 rotatably connected to the middle part of the inner side of the supporting top frame 1, and an arc-shaped rack 25 is fixedly sleeved on the outer surface of the rotating shaft 24. A middle gear 9 is rotatably installed in the middle part of the inner side of the supporting top frame 1, and the middle gear 9 is divided into The rotating shaft 24 is fixedly sleeved with a linkage gear 23 on one side, and a piston cylinder 27 is installed on the inner side of the supporting frame 1. A straight rack 22 is inserted and movably arranged at one end of the piston cylinder 27. The straight rack 22 is meshed and matched with the linkage gear 23. The upper surface of the supporting frame 1 is fixedly installed with an expansion assembly 553. A drainage channel 8 is arranged on one side of the drainage liner 21.

The upper ends of the two sliders 28 are rotatably connected with connecting rods 18. Both sides of the supporting top frame 1 are fixedly connected with pressure rods 16.

During the movement, the slider 28 is pushed to slide smoothly in the positioning slide 13. When the slider 28 slides, it pushes the two arc-shaped pressure plates 20 to be close to and overlap with the drainage lining 21, and the molten iron flows smoothly to the tapping channel 8 and flows to the next process. This is beneficial to the thermal tension damage of the drainage lining 21 when the molten iron is discharged during the iron jet, thereby reducing the occurrence of cracking and penetration.

The residue is sucked into the collecting hood 41, gathered at the inner end of the collecting hood 41 through the arc opening 42, slides downward into the discharge channel 32, and then enters the distributor 50 to be discharged. Then, the exhaust fan 58 cooperates with the suction generated by the fan 61 to suck the slightly larger attachments broken by the cleaning scraper 36 into the inlet 45 through the inlet 45, smoothly enters the discharge channel 40, and then is output to the distributor 50 through the aggregate hollow ring 49 to be discharged.
