A multi-degree-of-freedom submerged arc furnace plugging eye opening machine based on cutting eye opening

Abstract

The invention discloses a multi-degree-of-freedom submerged-arc furnace opening and plugging machine based on cutting type opening, which comprises a rotary cutting type opening machine, a plugging machine and a multi-degree-of-freedom adjustable type platform shared by the rotary cutting type opening machine and the plugging machine. The opening machine is of a rotary cutting type structure; a rotary cutting device, a propelling device and a telescopic arm are arranged on the opening machine; the propelling device propels the rotary cutting device to carry out feeding operation on the telescopic arm; and the multi-degree-of-freedom adjustable type platform is equipped with an amplitude varying device, a lifting device and a travelling device. According to a real-time position of a furnace hole, multi-degree-of-freedom position adjustment of each station is realized by virtue of lifting of the lifting device, angle increase and decrease of the amplitude varying device, extension and retraction of the telescopic arm and ring-shaped displacement of the travelling device; and the rotary cutting type opening is used to replace drilling of a conventional pneumatic or hydraulic rock drill, so that cost is reduced, and opening and hole-forming quality is improved.

Description

technical field [0001] The invention relates to a hole unblocking machine for a submerged arc furnace, in particular to a multi-degree-of-freedom hole unblocking machine for a submerged arc furnace based on a cutting type hole opening. Background technique [0002] For modern large-scale reduction submerged arc furnaces, the use of unplugging machines can reduce labor costs, keep the position of the furnace holes relatively fixed, make the output uniform and stable, shorten the time for unplugging holes, and reduce the maintenance period of furnace holes. With the optimization and adjustment of the domestic industrial structure, the continuous upgrading of industrial technology and technology, the outdated production capacity has been eliminated one after another, the large-capacity submerged arc furnace has increased rapidly, the hole diameter of the tapping furnace has also increased, and the rotary electric furnace has gradually increased, that is, the taphole It rotates ...

AI Technical Summary

Problems solved by technology

With the optimization and adjustment of the domestic industrial structure, the continuous upgrading of industrial technology and technology, the outdated production capacity has been eliminated one after another, the large-capacity submerged arc furnace has increased rapidly, the hole diameter of the tapping furnace has also increased, and the rotary electric furnace has gradually increased, that is, the taphole It rotates accordingly, and the position of the furnace hole is different each time. However, the traditional method of artificially burning the hole and filling the taphole has seriously affected the competition of domestic submerged arc furnace enterprises due to low efficiency, high labor intensity and poor safety. force

[0003] At present, the existing unplugging machines on the market have simple functions and poor operability. They lack the adjustment function of the station position such as the circumference, height and inclination angle of the submerged arc furnace, or the adjustment dimension of the station position is not enough, resulting in the inaccurate alignment. A single submerged arc furnace often needs multiple unplugging machines; most of the existing unplugging machines use pneumatic or hydraulic rock drills to open holes, which has a large impact and is easy to damage the furnace wall. Liquidity, and limited by the technology and cost of domestic rock drilling machines, the hole opening diameter is small; most of the working devices such as drill bits, drill pipes and plugging nozzles of existing hole plugging machines are made of high temperature resistant ordinary materials containing iron elements, while industrial silicon silicon The temperature of the water is higher than 1800°C, and the working devices of ordinary materials are easily corroded and damaged after contacting silicon water, and iron elements are precipitated to pollute the smelting melt and affect the quality of finished products

Most of the existing mud cannons for hole opening machines are integral or directly connected with bolts to the mud cannon head, which is difficult to disassemble and inconvenient to clear the mud after the hole is blocked

The above problems limit the use of the existing plugging machines on the market in large submerged arc furnaces, especially in industrial silicon furnaces. At present, domestic submerged arc furnace companies generally use artificial hole burning and plugging of tapholes.
