Specific embodiment
Core of the invention is to provide a kind of high temperature heat treatment furnace infrared temperature measurement system, effectively avoid interpolation blind pipe by
Stress fractures.
In order to make those skilled in the art more fully understand technical solution of the present invention, below in conjunction with attached drawing and specifically
Embodiment, explanation is described in detail to high temperature heat treatment furnace infrared temperature measurement system of the invention.
As shown in Figure 1, being the structural schematic diagram of high temperature heat treatment furnace infrared temperature measurement system provided by the invention；Include in figure
The structures such as fever burner hearth 1, guard shield 2, interpolation blind pipe 3, overhanging siphunculus 4, optical temperature measurement device 5, in the inner wall of fever burner hearth 1
Upper setting insulating layer, guard shield 2 are located at except fever burner hearth 1, form cavity between guard shield 2 and fever burner hearth 1.
Interpolation blind pipe 3 is inserted into from outside to inside in fever burner hearth 1, and the outer end of interpolation blind pipe 3 exposes to fever burner hearth 1；This
In signified inner end be the one end for being directed toward fever burner hearth 1, outer end is one end far from fever burner hearth 1.The inner end of interpolation blind pipe 3
For enclosed construction, outer end perforation setting；Interpolation blind pipe 3 is by 1 limited support of fever burner hearth, the main part quartile of interpolation blind pipe 3
Within fever burner hearth 1, the part of outer end exposes to the outside of fever burner hearth 1, guarantees the main part and hair of interpolation blind pipe 3
Sufficient heat exchange is realized in 1 inner cavity of hot stove thorax, keeps the temperature of 3 inner end of interpolation blind pipe equal with the fever temperature holding of burner hearth 1.
Overhanging siphunculus 4 is fixed on guard shield 2, identical as related interpolation blind pipe 3 above, overhanging siphunculus 4 in Fig. 1
Lower end close to fever burner hearth 1, be inner end；The upper end of overhanging siphunculus 4 is outer end far from fever burner hearth 1.Outside overhanging siphunculus 4
End stretches out in except guard shield 2；In the cavity that the inner end of overhanging siphunculus 4 is located at guard shield 2 between the burner hearth 1 that generates heat.
The inner end of overhanging siphunculus 4 is flexibly connected with the outer end of interpolation blind pipe 3 namely overhanging siphunculus 4 with interpolation blind pipe 3 is not
The relationship being fixedly connected, between the two can be along the relatively small rotational motion of same axis, can also be along the direction of axis relatively by a small margin
Translation.
Optical temperature measurement device 5 is set to the outer end of overhanging siphunculus 4, and the both ends of overhanging siphunculus 4 penetrate through setting, overhanging siphunculus 4
It is located on same axis with interpolation blind pipe 3, the outer end of interpolation blind pipe 3 is connected with overhanging siphunculus 4, and optical temperature measurement device 5 passes through
The infra-red radiation of interpolation blind pipe 3 can be detected in overhanging siphunculus 4.
Interpolation blind pipe 3 and the temperature inside fever burner hearth 1 are essentially identical, overhanging logical by being set to when measuring temperature
The optical temperature measurement device 5 of 4 outer end of pipe detects the infra-red radiation of interpolation blind pipe 3, further obtains the temperature inside fever burner hearth.
The inner end of overhanging siphunculus 4 is flexibly connected with the outer end of interpolation blind pipe 3, and two all and revocable integral structure；When
When the insulating layer to generate heat in burner hearth 1 is by high temperature deformation, interpolation blind pipe 3 is driven by insulating layer to be occurred mobile or rotates, and interpolation is blind
Pipe 3 is relatively movable with overhanging siphunculus 4 when being driven by insulating layer, is not in stress collection between interpolation blind pipe 3 and overhanging siphunculus 4
Middle phenomenon can avoid breakage problem, improve the service life of interpolation blind pipe 3.
On the basis of above scheme, high temperature heat treatment furnace infrared temperature measurement system of the invention further includes intermediate connection tube 6,
Intermediate connection tube 6 is independently of interpolation blind pipe 3 and overhanging siphunculus 4；The outer end of intermediate connection tube 6 is nested with the inner end of overhanging siphunculus 4
Grafting, the grafting nested with the outer end of interpolation blind pipe 3 of the inner end of intermediate connection tube 6.
By the way that intermediate connection tube 6 is arranged, the length of interpolation blind pipe 3 and overhanging siphunculus 4 can be reduced, facilitate and carry out assembly behaviour
Make；In addition, interpolation blind pipe 3 and overhanging siphunculus 4 can be translated or be rotated relative to intermediate connection tube 6, it is blind to further decrease interpolation
Pipe 3 is to influence caused by overhanging siphunculus 4.
When preferably, in order to guarantee that interpolation blind pipe 3 drives generation mobile or rotation by insulating layer, it is not connect as far as possible with centre
Pipe 6 contacts, and needs to have between intermediate connection tube 6 and overhanging siphunculus 4 and between intermediate connection tube 6 and interpolation blind pipe 3 enough
Gap；Since there are gaps, in order to avoid volatile matter enters what overhanging siphunculus 4, intermediate connection tube 6 and interpolation blind pipe 3 were formed
Within cavity, temperature measurement is interfered, gap and centre between intermediate connection tube 6 and overhanging siphunculus 4 is needed to connect
Isolating pad 7 is respectively set in gap between adapter tube 6 and interpolation blind pipe 3, and isolating pad 7 is flexible material, and isolating pad 7 does not influence centre
Connecting tube 6 and the relative motion of overhanging siphunculus 4 and the relative motion of intermediate connection tube 6 and interpolation blind pipe 3；Isolating pad 7 plays
The effect of foreign matter is isolated, ensure that temperature measurement accuracy to a certain extent.
Preferably, the isolating pad 7 in the present invention is graphitization carbon felt, is handled by carbon felt by high temperature graphitization, graphitization
The impurity of bulky grain can be isolated in carbon felt, do not completely cut off air.
Preferably, the overhanging siphunculus 4 in the present invention includes the fixed graphite inner tube and metal outer pipe of mutual sheathing, graphite material
Inner tube made of expecting has the performance of high temperature resistance, but graphite is more fragile, and metal tube is arranged in outer layer, it is ensured that overhanging siphunculus 4 has
There are enough structural strengths, more resistant to impact.
Interpolation blind pipe 3 is graphite-pipe or high-temperature ceramic, can bear high temperature.
Ring flange is arranged in upper end in the outer end setting ring flange namely Fig. 1 of interpolation blind pipe 3；On fever 1 top of burner hearth
Outer surface groove is set, for groove around through-hole for inserting interpolation blind pipe 3, the outer end of interpolation blind pipe 3 passes through ring flange
It is installed in the groove of fever 1 outer surface of burner hearth setting, to limit the circumferential position of interpolation blind pipe 3.
Ring flange is arranged in the middle part of overhanging siphunculus 4, and ring flange in a ring, protrudes from the outer surface of overhanging siphunculus 4；It is overhanging logical
Pipe 4 is bolted by ring flange with guard shield 2 and is connect.
On the basis of any of the above-described technical solution and its intercombination, purification is set on the overhanging siphunculus 4 in the present invention
Air intake duct 8 is passed through purification gas, such as argon gas or nitrogen into overhanging siphunculus 4 by purifying air intake duct 8；It is set on fever burner hearth 1
Purification gas off-take 9 is set, for purification gas to be discharged.
Purification gas from the cavity that purification air intake duct 8 enters overhanging siphunculus 4, intermediate connection tube 6 and interpolation blind pipe 3 are formed it
It is interior, air-flow is formed, the little particle interference impurity in this cavity drives with air-flow, enters fever burner hearth 1 and protection by isolating pad 7
In cavity between shell 2, and further it is discharged from purification gas off-take 9.
