Problems solved by technology

Among the tuyere components, the tuyere sleeve closest to the furnace is very easy to burn out and needs to be replaced frequently, especially in the later period of the furnace, the replacement is very frequent
[0003] Depending on the size of the furnace capacity, the blast furnace contains several to dozens of tuyeres. Therefore, the number of small tuyere sets that need to be replaced every time the blast furnace is shut down is large, and the workload is large; In order to achieve the effect of sealing, and due to the high temperature and thermal stress, it is extremely difficult to remove the small tuyere sleeve from the middle sleeve, the work is difficult and time-consuming

Abstract

The invention discloses a dismantling mechanism for a small tuyere cover, which includes a push rod device, a cylinder body installed on the head of the push rod device, a plurality of claws embedded in the cylinder body and retractable relative to it, and a connecting hook. The claw and the elastic part of the cylinder, wherein each claw is provided with an elastic piece, and one end of the claw is provided with a sharp-shaped barb for hooking the small sleeve of the tuyere. The barb hooks the small sleeve of the tuyere, and the cylinder is hinged to the cylinder through a hinge. The dismantling mechanism for the small tuyere sleeve proposed by the present invention has a simple and reliable structure and is easy to use.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment, in particular to a disassembly mechanism for a small tuyere and a disassembly method thereof. Background technique [0002] During the smelting process of the iron-making blast furnace, it is necessary to blow hot air of about 1100 ℃ to the blast furnace through multiple tuyere. Among the tuyere components, the tuyere sleeve closest to the furnace is very easy to burn and needs to be replaced frequently, especially in the later stage of the furnace age, and the replacement is very frequent. [0003] The blast furnace contains several to dozens of tuyere depending on the size of the furnace. Therefore, the number of small tuyere sets that need to be replaced each time the blast furnace is stopped is large, and the workload is large; In order to achieve the sealing effect, due to the effect of high temperature thermal stress, it is extremely difficult to remove the small tuyere sle...
