Abstract
The utility model discloses a blast furnace tuyere platform capable of effectively preventing temperature rise deformation, and relates to a matching structure between a blast furnace (3) and a tuyere platform (2). The bottom of the tuyere platform (2) above a tapping channel of the blast furnace (3) is fixedly connected with a water cooling device (1). According to the blast furnace tuyere platform, the water cooling device is distributed uniformly at the bottom of the tuyere platform, namely, on one side facing a main tapping channel of the blast furnace, so that during work, water circulation is performed, heat is discharged along with water circular flow, due to snake-shaped tube nest arrangement, water resistance is increased, water flow time is prolonged, a temperature reduction effect is improved, and the tuyere platform is protected effectively. The blast furnace tuyere platform is simple in structure and stable and reliable in work, and the heat radiating efficiency of the tuyere platform is improved greatly. The tuyere platform has the advantages of small investment and convenience in mounting and maintenance, meanwhile, only simple water cooling equipment is required to be added, and power equipment is not required to be added, so that the technical effect of energy conservation is provided.
Description
Technical field
The utility model belongs to smelting equipment technical field, is specifically related to a kind of simple in structurely, and working stability can effectively prevent the blast furnace tuyere platform of temperature rise distortion reliably.
Background technology
Current domestic large blast furnace ironmaking, stokehold all adopts iron storage type major groove, and tap drain is longer, thermal radiation is larger, at blast furnace, produce and tap a blast furnace in process, be accompanied by molten iron and flow out from iron notch, can produce a large amount of, lasting high temperature heat, tapping a blast furnace, tap drain around produces compared with heat-flash radiation, especially the tuyere platform thermal load of being located at tap drain top is high, often causes steel platform structure distortion, and resistance to material comes off, increase enterprise's maintenance cost, also can cause whole Working environment to worsen.All to stop production every year maintenance ，Gei enterprise result in greater loss, if be equipped with extra cooling system, can increase enterprise's production cost.For this reason, guaranteeing that under system for blast furnace ironmaking safe and stable operation, special development is a kind of simple in structure, with low cost, the tuyere platform refrigerating unit with effective temperature-reducing is the key addressing this problem.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, and working stability is reliable, can fully can effectively prevent the blast furnace tuyere platform of temperature rise distortion.
The purpose of this utility model is achieved in that the fit structure relating between blast furnace and tuyere platform, the affixed water cooling plant in tuyere platform platform bottom of described blast furnace iron outlet groove top.
The utility model adopts in tuyere platform bottom and towards the one side of blast furnace tapping main channel, is evenly covered with water cooling plant; when work; water flowing circulation; along with circulating of water discharged heat; owing to having adopted snakelike tubulation, arrange the resistance that has increased water; the flowing time that has extended water, has improved cooling-down effect, has effectively protected tuyere platform.The utility model is simple in structure, and working stability is reliable, greatly improves the radiating efficiency of tuyere platform.Have little, the convenient for installation and maintenance advantage of investment, only need increases simple water cooling equipment simultaneously, does not need to increase power-equipment, has energy-conservation technique effect.

In figure: 1-water cooling plant, 2-tuyere platform, 3-blast furnace, the 4-tap drain that taps a blast furnace, 5-casting house.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail, but never in any form the utility model is limited, and any conversion of doing based on the utility model training centre, all falls into the utility model protection domain.
As shown in Figure 1 and Figure 2, the utility model relates to the fit structure between blast furnace 3 and tuyere platform 2, the tuyere platform 2 affixed water cooling plants 1 in platform bottom of described blast furnace 3 casting house tops.
Described water cooling plant 1 is that snakelike tubulation is arranged, and is evenly covered with whole tuyere platform 2 bottoms.
Described water cooling plant 1 is that snakelike tubulation is arranged, and non-uniform Distribution is in tuyere platform 2 bottoms.
Described water cooling plant 1 is arranged for rectilinearity tubulation, is evenly covered with whole tuyere platform 2 bottoms.
Described water cooling plant 1 is arranged for rectilinearity tubulation, and non-uniform Distribution is in tuyere platform 2 bottoms.
Described water cooling plant 1 arranges water-in 3 and water outlet 4.
Described water-in 3 arranges gate valve 5 with water outlet 4.
Described gate valve 5 is a kind of in manual, pneumatic, hydraulic pressure or solenoid electric valve.
Described water cooling plant 1 connecting pipe road is rigid structure.
principle of work of the present utility model and process:
The bottom of the tuyere platform of the utility model above iron notch is affixed to be covered with snakelike tubulation and to arrange water cooling plant.When work, carry out water flowing circulation temperature lowering, by the fluxion strap of water, walk the heat of tuyere platform, owing to having adopted snakelike tubulation arrangement architecture to increase the flowing time of water, improved cooling efficiency, after overcooling, the temperature of tuyere platform is reduced greatly.Easy maintenance after equipment is installed, does not need to increase external impetus energy device, energy-conservation easy again.This time change the effect of playing auxiliary temperature-reducing, guaranteed the normal operation of equipment, extended work-ing life.By the tuyere platform above each iron notch before improving, at least safeguard once and calculate every year, after improving, tuyere platform does not need to safeguard, saves every year 750000 yuan of maintenance costs.Through the operation of one-year age, cooling-down effect is obvious.
