Abstract
The utility model relates to a blast furnace hot blast short pipe, in particular to a repair device for the inner walls of a blast furnace hot blast short pipe. A repair spraying device for the inner walls of the blast furnace hot blast short pipe comprises a spray gun with cooling water pipes, a water source for providing cooling water, and a rectangle holder which can be arranged in the hot blast short pipe, wherein the spray gun can rotate around a rotation center or is arranged on the holder in fore-and-aft movement, and a cooling water channel is arranged in the holder, wherein one end of the cooling water channel is provided with a cooling water inlet and a cooling water outlet which are communicated with the water source. The utility model can repair lining fire-proof material in a hot blast furnace hot blast short pipe in the shorter blast furnace damping-down time, no needing to reduce the temperature in the hot blast short pipe into the ambient temperature.
Description
Technical field
The utility model relates to the blast-furnace hot-air short tube, relates in particular to a blast-furnace hot-air short tube inwall prosthetic device.
Background technology
Wind furnace is the hot air source of blast-furnace hot-air, guarantees the normal operation of blast furnace through hot blast short pipe supply hot blast.Hot blast short pipe is owing to the variation of cold and hot air movement, high pressure-temperature gas washes away and reasons such as short tube expansion joint extruding, make in the short tube high alumina brick of working lining fragmentation can occur and fall, high temperature arrives permanent layer, through the disruptive cast bed of material, influence iron-clad, cause the short tube iron-clad rubescent.This moment must be to the place under repair of hotblast stove inner lining refractory.
Yet, if the time of blast furnace staying is all shorter, so is difficult in the short tube drop to and can enters the temperature that the maintainer overhauls, so can't directly repair it damping down the time.Enter short tube with respect to the operating personnel and directly repair, it is a kind of effective maintenance mode that liner is sprayed, and it is convenient and swift, when guaranteeing repair quality, can also finish maintenance in the time at short blast furnace staying.But no matter be directly to enter in the stove maintenance or carry out spray treatment, irrespective problem all must not be in the furnace temperature cooling.
Summary of the invention
The utility model is intended to address the deficiencies of the prior art, and provides a kind of blast-furnace hot-air short tube inwall to repair spray equipment.The utility model does not need temperature in the heating duct is dropped to room temperature, in the time, implements the maintenance to the hot air furnace hot air short pipe inner lining refractory at short blast furnace staying.
The present invention is achieved in that a kind of blast-furnace hot-air short tube inwall reparation spray equipment, comprise the spray gun that has cooling water pipeline, and the water source that water coolant is provided, it comprises that also can place the rectangular bracket in the described hot blast short pipe pipe, described spray gun can be around rotating the center rotation or being arranged on movably forward and backward on the described carriage, and being provided with cooling-water duct in the described pallet body, an end is provided with entrance of cooling water and the cooling water outlet that is communicated with the water source.
Described blast-furnace hot-air short tube inwall is repaired spray equipment, described spray gun comprises rifle body, shower nozzle, rotating mechanism and balancing weight, described shower nozzle is arranged on rifle body one end side surface, and described rotating mechanism for outwards distribute radially from central division and an end be connected some quarter butts on the sidewall of rifle body rear end, described balancing weight is arranged on the rifle body rear end.
Described blast-furnace hot-air short tube inwall is repaired spray equipment, and described quarter butt has three to four, is arranged on to their equi-spaced apart the external side of rifle.
Described blast-furnace hot-air short tube inwall is repaired spray equipment, described carriage is a rectangular frame, be provided with a spill roller on its front-end and back-end separately to support described spray gun rifle body, the side, rear end is provided with the baffle plate that limit bracket stretches into hot blast short pipe, and described entrance of cooling water and cooling water outlet are located at back-end framework.
The utility model is by design spill roller on carriage, can make nozzle be positioned at the moving forward and backward and rotating freely of the lateral spray gun of lance head, and spray gun is positioned at and is parallel on the hot blast short pipe axial line, and nozzle can spray the hot blast short pipe liner outside stove.Its implementing process is simple, simple for production, the very low and usage period limit for length of installation cost, can just finish the maintenance of hot blast short pipe liner at very short blast furnace staying in the time, need not to enter under the high-temperature condition in the stove operation or for a long time could operation behind the black furnace, is desirable, practical hot blast short pipe liner repair apparatus.
