Abstract
The utility model relates to a thermometer of the roof gas temperature of the blast furnace. A blast furnace cross-thermometer capable of changing couple during production comprises a thermocouple, a cross thermo-metering support, a thermocouple fixing equipment, and a blankoff flange. A jettison valve is arranged between the blankoff flange and the thermocouple fixing equipment. The jettison valve is a 3/8 ball valve. The utility model can realize the replacement of the damaged cross thermo-metering thermocouple in the condition of regular production.
Description
1, technical field
The utility model relates to a kind of pick-up unit of State of Blast Furnace Top gas temperature.
2, background technology
Blast furnace cross temperature measuring equipment is made up of cross temperature frame, cross temperature support and cross temperature galvanic couple three parts usually, the cross temperature frame is installed in blast furnace furnace roof inside, the cross temperature support is installed in the cross temperature frame, the cross temperature galvanic couple is installed in the cross temperature support, and the galvanic couple head stretches out the cross temperature support and contacts with coal gas stream in the stove.At present, existing cross temperature measurer is only considered the sealing property of cross temperature measurer in order to prevent gas leakage, structurally with the fixation of cross temperature galvanic couple.Because blast furnace produces a large amount of high pressure gas aborning, when in blast furnace production process, carrying out the replacing of cross temperature galvanic couple, will have a large amount of blast furnace gases and blow out, threatening workmen's safety, can't carry out site operation.Therefore, burn out, can only wait by the time and change the cross temperature frame behind the blast furnace staying, and then change the cross temperature galvanic couple in case the cross temperature galvanic couple takes place in blast furnace production process.The judgement of blast furnace operating personnel be will have influence on like this, thereby stable, the direct motion of blast furnace had influence on coal gas distributions in the State of Blast Furnace.
3, summary of the invention
The utility model provides a kind of blast furnace cross temperature measuring equipment that can change galvanic couple aborning, in case galvanic couple burns out in blast furnace production process, can in time change.
In order to solve the problems of the technologies described above, the technical solution of the utility model: a kind of blast furnace cross temperature measuring equipment that can change galvanic couple aborning, be made up of thermopair, cross temperature support, galvanic couple stationary installation, blind plate, characteristics are between blind plate and galvanic couple stationary installation stop valve to be housed.
Described stop valve is a ball valve.
Described ball valve is 3/8 ".
Compare with prior art, the advantage of the technical program is: at the cross temperature galvanic couple, after promptly thermopair damaged, unnecessary blast furnace staying by the time can be changed the galvanic couple operation in blast furnace production process.So just can guarantee that the cross temperature galvanic couple can flow temperature conditions by continuous detecting coal gas, analyze, judge, adjust coal gas for operating personnel and flow, thereby guarantee the blast furnace stable smooth operation.
4, description of drawings:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation that can change the blast furnace cross temperature measuring equipment of galvanic couple aborning.
5, embodiment:
In conjunction with the accompanying drawings 1, a kind of blast furnace cross temperature measuring equipment that can change galvanic couple aborning is made up of thermopair 1, galvanic couple stationary installation 2, stop valve 3, blind plate 4 and cross temperature support 5; Whole device is installed on the thermometric frame that has circulating water cavity.Thermopair 1 inserts cross temperature support 5, cross temperature support 5 is fixed on the galvanic couple stationary installation 2, blind plate 4 is contained on the cross temperature support 5, between blind plate 4 and galvanic couple stationary installation 2 stop valve 3 is housed, and whole blast furnace cross temperature measuring equipment is fixedly mounted on the blast furnace throat position by blind plate 4.When thermopair 1 damages, unclamp galvanic couple stationary installation 2, slowly extract the thermopair 1 of damage, allow the thermopair head leave stop valve 3, close stop valve 3, unload galvanic couple stationary installation 2, take out the thermopair 1 that damages.In the present embodiment, stop valve is a ball valve, and is 3/8 " ball valve.During installation, on new galvanic couple 1, put galvanic couple stationary installation 2, new galvanic couple 1 is slowly inserted, allow galvanic couple 1 head arrive stop valve 3, slight fastening galvanic couple stationary installation 2, open stop valve 3 then, thermopair 1 is injected cross temperature support 5 to requiring the degree of depth, close stop valve 3 and fastening galvanic couple stationary installation 2.
Claims (3)
1, a kind of cross temperature measurer that can change galvanic couple aborning is made up of thermopair, cross temperature support, galvanic couple stationary installation, blind plate, it is characterized in that: between blind plate and galvanic couple stationary installation stop valve is housed.
2, the cross temperature measurer that can change galvanic couple aborning according to claim 1, it is characterized in that: described stop valve is a ball valve.
3, the cross temperature measurer that can change galvanic couple aborning according to claim 2, it is characterized in that: described ball valve is 3/8 ".
