Manipulator and equipment for unblocking small sleeve tuyere of blast furnace

Abstract

The invention discloses a manipulator and equipment for unblocking a small sleeve tuyere of a blast furnace. The manipulator comprises a feeding pipe, a sleeve and a fixed seat which are connected in sequence. The feeding pipe is provided with a material storage cavity used for containing sealing materials, and a discharging hole is formed in the side, close to the tuyere, of the feeding pipe. The sleeve communicates with the material storage cavity, and a push-pull piece and a driving piece connected with the push-pull piece are arranged in the sleeve. Under the driving action of the driving piece, the push-pull piece has an extrusion state that the sealing materials in the material storage cavity are pushed out of the discharging hole to seal the tuyere, and has an extension state that the push-pull piece extends out of the discharging hole to poke the sealing materials fixed to the tuyere. The manipulator and equipment for unblocking the small sleeve tuyere of the blast furnace are reasonable in design, simple in structure, easy to machine and operate, practical and convenient, the accuracy of unblocking and blocking of the tuyere is ensured, waste of the sealing materials is reduced, the use efficiency of the tuyere is improved, the workload of field treatment is reduced, the labor cost is saved, and meanwhile the operation time is shortened.

Description

technical field [0001] The application relates to the technical field of metallurgy and ironmaking, and in particular to a manipulator and equipment for unclogging a small tuyere of a blast furnace. Background technique [0002] The tuyere of the blast furnace in the ironworks is a part of the blast furnace in the ironworks. During ventilation, the high-temperature hot air blown in from the tuyere of the blast furnace and the coke at the bottom of the furnace are oxidized and burned to generate carbon monoxide (CO). CO reduces the iron that originally existed in the form of oxides during the high temperature rise. , the blast furnace will adopt the process of blocking the tuyeres of the blast furnace when the blast furnace is shut down or when dealing with special furnace conditions, which requires the ability to open and block the tuyere at any time. At present, most of the tuyeres on the market are artificially blocked by refractory mud, but due to the small space of the s...

AI Technical Summary

Problems solved by technology

At present, most of the tuyere is artificially blocked by refractory mud on the market, but due to the small space of the small set of tuyere, this makes it more difficult for technicians to operate

Moreover, because the refractory mud itself is relatively soft, the operating level of the technicians themselves is also uneven, and the thickness of the small set of tuyere when it is blocked by the refractory mud cannot be accurately grasped.

Therefore, in the actual operation process, if the refractory mud is too little or too thin, the blocked small tuyeres are easily blown away by high-temperature hot air; Vent

Furthermore, if the refractory mud is not at the front end of the small sleeve, it is likely to cause the small sleeve to be burnt out or burn through, thereby increasing the workload of the workers and delaying the recovery time, thereby seriously affecting the use of the blast furnace and production efficiency
