Static pressure tong-type fire door cleaning method and cleaner thereof

Abstract

A clean method and a device for metallurgy static pressure pincers furnace mouth are provided. The method is by use of a 360** rotary pincers to grip the slag on the furnace mouth and by use of the hydraulic pressure to crush the slag. The corresponding cleaning device comprises top connector, motor, rotary supporter, oil tank, bracket and pincers. The motor is fixed to the top connector. A small gear is fixed to the output shaft of the motor. The outer race of the rotary supporter is connected to the top connector. The inner race of the rotary supporter meshes with the small gear. The bracket is fixed to the inner race of the rotary supporter. One end of the oil tank is connected to the bracket and the other end is connected to a hole of the pincers. The other hole of the pincers is connected to the bracket.

Description

Technical field: [0001] The invention belongs to the field of metallurgical industry, and in particular relates to a method and equipment for cleaning blast furnace mouths in the metallurgical industry. Background technique: [0002] At present, in all metallurgical industries, during the blast furnace smelting production process, the normal production is often affected by the slagging at the furnace mouth, and the furnace mouth slagging must be cleaned every 3-4 hours. At present, the impact cleaning method is used. The disadvantages are noise and dust, low cleaning efficiency, high purchase and maintenance costs, and the most serious problem is that there is strong vibration to all blast furnace linings (refractory bricks). The contact area between the chisel rod and the slag is small, the shape of the slag is not flat, and the positioning is often inaccurate and off-center. Sometimes the operation error directly damages the furnace mouth, which seriously affects the norma...

Problems solved by technology

At present, the impact cleaning method is used. The disadvantages are noise and dust, low cleaning efficiency, high purchase and maintenance costs, and the most serious problem is that there is strong vibration to all blast furnace linings (refractory bricks). The contact area between the chisel rod and the slag is small, the shape of the slag is not flat, and the positioning is often inaccurate and off-center. Sometimes the operation error directly damages the furnace mouth, which seriously affects the normal production and shortens the normal service life of the blast furnace. Every year, the metallurgical industry The loss of repair and maintenance costs due to blast furnace vibration damage, shutdown maintenance and impact damage to blast furnace equipment (impact furnace mouth cleaning machine) is as high as hundreds of millions of yuan
