Abstract
The utility model relates to a detecting device for the damage of the second sleeve of a blast furnace tuyere, which is formed by a water inlet and drain pipe, a drain valve and a pressure gauge. The utility model is characterized in that one end of the water inlet and drain pipe is connected and communicated with the water inlet and air exhaust pipe of a soft water closed circulating cooling system, the other end of the water inlet and drain pipe is connected with the drain valve and the pressure gauge is arranged on the water inlet and drain pipe. The pressure gauge is used to detect the damage situation of the second sleeve of the blast furnace tuyere, the damage can be accurately judged according to the pressure gauge regardless of the severity of the damage of the second sleeve of the blast furnace tuyere, the operation is simple, the spent time is short and the labor strength of workers is greatly reduced. The connection speed is fast, only 2 to 3 minutes are required, the connection is firm and the safety is reliable. The popularization value is wide. Since the original hose for temporarily cooling water supply is replaced by the metal hose and the original binding iron wire is replaced by the rapid loose joint, the connection is simple, rapid and fully reliable.
Description
Technical field
The utility model belongs to a kind of steel plant blast furnace pick-up unit, is a kind of blast-furnace tuyere two cover damage detection devices specifically.
Background technology
The soft water airtight circulating cooling system of steel plant's blast-furnace tuyere two covers is made of soft water feed water valve, soft water feed pipe, water inlet vent valve, water inlet gas outlet, SWR, soft water back-water valve (BWV), backwater exhaust valve, drainpipe and rhone at present, its structure is: the soft water feed pipe communicates with blast-furnace tuyere two cover soft water water inlets by the soft water feed water valve, and the soft water feed pipe also communicates with the water inlet gas outlet by the water inlet vent valve; SWR communicates by soft water back-water valve (BWV) and blast-furnace tuyere two cover soft water water delivering orifices, and SWR is also by backwater exhaust valve and drainpipe communicate with rhone (Fig. 1).
The breakage of steel plant blast furnace soft water closed circulation cooling system air port two covers at present detects and has following characteristics:
(1) because unspecial breakage is monitored and changed the open circuit pick-up unit, can only observe two cover freeing port draining phenomenons artificially, detect judgement with the personal experience, the true accurately foundation of neither one intuitively detects judgement.
(2) cover residing position in air port two is near furnace wall, and gas pressure is relatively low herein, as damaged position in the air port two cover bottoms, then water seal can't be discharged and be formed to surplus water in two covers, thereby form the normal illusion of draining, makes damaged two covers can't be difficult to find.
Interim feed pipe when (3) handling is to connect interim hose to link to each other with service water, interface is to use the iron wire tighten, owing to tie up the position of iron wire between two warm-air pipes, and near the stove skin pipeline is more herein, the advancing of air port two cover, three covers, backwater cooling water pipe, the warm-air pipe head cools off into, the pull bar of return pipe and warm-air pipe all is located at herein, job position is narrow, and environment temperature is generally all about 60 ℃, gas content is big, sometimes up to more than the 2000PPm, must wear the respirator operation, consuming time longer, tie up be not close to the time water supply sebific duct come off easily.Make the two no water coolings of cover and cause two covers to burn accident.
(4) hose that temporarily supplies water is damaged easily, in case damaged, the water supply of two covers spill from breakage, and two cover outputs are reduced and the generation that causes the accident.
Summary of the invention
The purpose of this utility model is to change original to detect the breakage of judging air port two covers with artificial empiric observation, and providing a kind of is that the blast-furnace tuyere two of the detection quick and precisely that rests on a scientific basis overlaps damage detection devices with the pressure gauge pressure, with data.
To achieve these goals, the utility model is made of water inlet drainpipe, draining valve and tensimeter, be characterized in: the water inlet gas outlet of an end and the described soft water airtight circulating cooling system of water inlet drainpipe connects and communicates, and other end connection draining valve, tensimeter are arranged on on the water drainpipe.
Above-mentioned water inlet drainpipe is provided with one with the water inlet gas outlet connection place of described soft water airtight circulating cooling system and connects articulation, the described connection articulation connection that matches with a connecting port of the water inlet gas outlet union end of described soft water airtight circulating cooling system.
The utility model adopts tensimeter to detect the damaged situation of blast-furnace tuyere two covers, and no matter air port two covers damage sizes can both accurately be judged from tensimeter, and simple, the consuming time weak point of method of operating and significantly reduce labor strength.This connection speed is fast, only needs to finish in 2-3 minute, connects fastening, safe and reliable.The utlity model has promotional value widely.Change the original interim cooling used hose that supplies water and use metal hose instead and connect, will formerly tie up iron wire and connect and use quick loose joint instead and connect, simple, fast, fully reliably.
Description of drawings
Fig. 1 is the soft water airtight circulating cooling system theory diagram of blast-furnace tuyere two covers.
Fig. 2 is the utility model structural representation.
Among the figure: two covers of 1-air port; 2-soft water feed pipe; The 3-SWR; The 4-tensimeter; 5-connects articulation; The 6-connecting port; The 7-vent valve of intaking; 8-backwater exhaust valve; 9-soft water feed water valve; 10-soft water back-water valve (BWV); The 11-drainpipe of intaking; The 12-draining valve; The 13-drainpipe; The 14-rhone; The 15-gas outlet of intaking.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
The utility model is made of water inlet drainpipe, draining valve and tensimeter, and an end of water inlet drainpipe connects with the water inlet gas outlet of described soft water airtight circulating cooling system and communicates, and other end connection draining valve, tensimeter are arranged on on the water drainpipe; The water inlet drainpipe is provided with one with the water inlet gas outlet connection place of soft water airtight circulating cooling system and connects articulation, the connection articulation connection that matches with a connecting port of the water inlet gas outlet union end of soft water airtight circulating cooling system.
Because air port two covers are installed in the last furnace shell, after air port in the soft water airtight circulating cooling system (Fig. 1) two cover soft water feed water valves, soft water back-water valve (BWV) closed, form a closed container that includes 1.0Mpa soft water in the two cover bodies of air port, if air port two covers are damaged, the soft water of 1.0Mpa will leak in the lower stove of pressure (furnace pressure is 0.3Mpa) from breakage in the two cover bodies of air port.Tensimeter just can intuitively show.The utility model utilizes the difference (soft water hydraulic pressure 1.0Mpa, furnace pressure are 0.3Mpa) between air port two cover cooling soft water hydraulic pressure and State of Blast Furnace internal pressure, adopts tensimeter to build the pressure and detects the damaged situation of air port two covers.
It is as follows that the utility model specifically detects step:
1, water inlet drainpipe of the present utility model is connected with the water inlet gas outlet of soft water airtight circulating cooling system by connecting articulation;
2, open soft water water inlet vent valve, the visible pressure of tensimeter shows;
3, close soft water water supply valve, soft water backwater valve;
4, observe tensimeter, descend and the furnace pressure balance as pressure, then two covers are damaged, and pressure stability or thermal expansion are risen, and then two covers are not bad;
5, after definite the damage, it is pending to recover normal water supply.
The content that is not described in detail in this instructions belongs to this area professional and technical personnel's known prior art.
