Abstract
The utility model discloses a kind of improved cross thermocouple for blast furnace protection device; including high-temperature alloy sleeve pipe; high-temperature alloy sleeve pipe is cylindrical tube; one end of high-temperature alloy sleeve pipe is connected to the tubaeform cylinder with Closed End; be centrosymmetric on Closed End it is uniform be arranged at intervals five M16 thermometer holes, Closed End it is centrally disposed a M16 thermometer hole.It is totally-enclosed that the utility model using high-temperature alloy sleeve pipe carries out high temperature, completely cut off it is outside corrode, ensure that thermocouple can still stand intact under the concussion of high intensity, and can be with high temperature resistant and corrosion-resistant.Sealing is good, is easy to blast furnace to carry out individually checking and changing to thermocouple not under damping down state, meets the demand of production technology to greatest extent.
Description
Technical field
It the utility model is related to a kind of improved cross thermocouple for blast furnace protection device.
Background technology
The basic structure of the thermocouple used in iron industry is thermode, insulating materials and protection sleeve pipe, and with display
Instrument, recording apparatus or computer etc. support the use.Cross thermocouple is the visual plant of measurement and control temperature, residing
Working environment it is extremely severe, longtime running in 1000 DEG C of high temperature above, hyperbaric environments, by high velocity air impact and high temperature
The influence of flue dust, its performance quality and service life directly influence production safety, process control and production cost.In reality
The problem of often generation measurement accuracy is forbidden in production, protective cover for thermocouple fracture, and service life is shorter, do not run reliably
Cycle.When thermocouple break, need blast furnace periodical repair to split out the thermocouple that could change damage after cross temperature measurer, thermocouple by
Damage is universal, and spare parts consumption amount is big.As blast furnace maximizes, automates, the demand for development of high blast, high wind-warm syndrome, to thermocouple
It is proposed new, tightened up requirement.Therefore improving thermocouple service life also turns into blast furnace steady production key component.
Existing thermocouple is single ply protective sleeve pipe, and 6 or 7 thermocouples are independently embedded in blast furnace cross temperature measuring equipment
In, original device protection sleeve pipe is open, and temperature measuring point head exposure is easily rotten by furnace high-temperature under furnace high-temperature environment
Crude fuel washes away and into inside protection sleeve pipe, causing thermocouple and protection sleeve pipe hardened to together, causes thermoelectricity in erosion and stove
Replacing can not be removed after even damage, influences in-furnace temperature detection, the normal production to blast furnace adversely affects.
The content of the invention
The purpose of this utility model is to provide a kind of improved cross thermocouple for blast furnace protection device, can be effective
Ground prevents thermocouple break, extends the service life of thermocouple.
The purpose of this utility model is achieved in that a kind of improved cross thermocouple for blast furnace protection device, bag
High-temperature alloy sleeve pipe is included, high-temperature alloy sleeve pipe is cylindrical tube, and one end of high-temperature alloy sleeve pipe is connected to blind end
The tubaeform cylinder in face, it is centrosymmetric on Closed End and is uniformly arranged at intervals five M16 thermometer holes, Closed End is centrally disposed
A M16 thermometer hole, a high-temperature alloy protecting tube is put in the installing of high-temperature alloy jacket exterior spacer sleeve.
The utility model is totally-enclosed using high-temperature alloy sleeve pipe and high-temperature alloy protecting tube progress high temperature, and isolation is outer
Portion corrodes, and ensures that thermocouple can still stand intact under the concussion of high intensity, and can be with high temperature resistant and corrosion-resistant.Sealing is good
It is good, it is easy to blast furnace to carry out individually checking and changing to thermocouple not under damping down state, meets life to greatest extent
The demand of production. art.
According to the demand of production technology, the thermocouple that 6 insertion different depths are fixedly mounted enters the totally-enclosed protection of high temperature
In sleeve pipe, thermocouple and protection nested structure are all introduced into cross temperature measurer after this improvement.Due to the totally-enclosed alloy of high temperature
Steel Thermal conductivity, it still can guarantee that the measurement accuracy of each temperature measuring point.
The utility model is simple in construction, can effectively prevent thermocouple break, extends the service life of thermocouple.
Brief description of the drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is main structure diagram of the present utility model；
Fig. 2 is amplification side structure schematic view of the present utility model.
