Abstract
The utility model discloses a high-temperature-resistant high-pressure-resistant sealed reliable hot-blast stove peephole device which comprises a peephole cover plate (1), a transition plate (2), a special plug valve (3) for a blast-furnace tuyere, a peep mirror (4) and a peep cap (5), wherein the transition plate (2) is arranged on the middle surface of the peephole cover plate (1); one end of the special plug valve (3) for the blast-furnace tuyere is detachably and hermetically fixed with the inner wall of the transition plate (2), and the other end of the special plug valve (3) for the blast-furnace tuyere is detachably and hermetically fixed with the inner wall of the peep cap (5); the peep mirror (4) is arranged in the peep cap (5). According to the hot-blast stove peephole device, a structure that the special plug valve for the blast-furnace tuyere and a peephole are arranged on the peephole cover plate is adopted, the valve and the peephole are hermetically and fixedly connected to the middle of the peephole cover plate of a hot-blast stove through pipe threads and can suffer from high temperature and high pressure, the problem of hot air leakage in production can be effectively solved, and the flame combustion situation can be intuitively observed. The hot-blast stove peephole device has the characteristics of being simple in structure, convenient to operate, safe and reliable.
Description
Technical field
The utility model relates to a kind of smelting equipment technical field, is specifically related to a kind of simple in structurely, and easy to operate high temperature high voltage resistant seals reliable hotblast stove peephole device.
Background technology
Hotblast stove be one for technological process provides the thermal apparatus that completes combustion processes and heat transfer process of hot blast, its structure comprises the combustion unit that fuel burns therein, and air-flow carries out the heat transfer unit (HTU) of thermal exchange therein.For the regenerative hot blast stove of hot blast is provided for blast furnace, just must have combustion chamber and the burner of the combustion processes of realizing, and heap exoergic completes the regenerator of the heat storage of heat transfer process; In order to organize air-flow and to realize the switching of air-flow process, realize the cold air chamber of distribution of air flow and various import and export and valve and be also absolutely necessary.In addition,, because the required hot blast of blast furnace has certain pressure, a metal shell that can bear pressure is also absolutely necessary for this reason.Therefore, hotblast stove is exactly a pressure resistant vessel of building refractory materials in metal shell by laying bricks or stones.Hotblast stove of the prior art is top combustion stove, and burner, in high-temperature zone, hotblast stove top, when current check Combustion of Hot Air Furnace situation, must directly be observed flame color by opening the anterior valve of peep hole.Trip valve when original design peep hole adopts ordinary ball valve as non-observation.Because head temperature is higher, in hot-blast stove baking oven process, ball valve is often damaged by high temperature, and hotblast stove inside is high temperature and high pressure environment in normal productive process, will cause hot blast to leak the equipment that burns out once valve damages.For this reason, developing a kind of simple in structure, easy to operate high temperature high voltage resistant, to seal reliable hotblast stove peephole device be the effective way addressing this problem.
Utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, and easy to operate high temperature high voltage resistant seals reliable hotblast stove peephole device.
The purpose of this utility model is to realize like this, comprise peep hole cover plate, rebound, blast-furnace tuyere plug valve special, sight glass and spy on cap, described rebound is arranged at peep hole cover plate middle part surface, within blast-furnace tuyere plug valve special one end and rebound, wall removable seal is fixed, the other end with spy on wall removable seal within cap and fix, spy on cap inside sight glass be set.
The utility model adopts the structure that special blast furnace stopcock and peep hole are set on blast furnace tuyere monitoring cover plate, be consolidated in hotblast stove peep hole cover plate middle part by pipe thread seal, this valve and peep hole can bear high temperature, high pressure, the hot blast problem that leaks in producing can be effectively avoided, and flame situation can be observed more intuitively.The utlity model has simple in structure, easy to operate, safe and reliable feature.
