Abstract
The utility model discloses a special platinum rhodium thermocouple of coking stove, this thermocouple include outer protective sheath and be located the thermocouple wire of this skin protective sheath, on this thermocouple wire still the cover be equipped with silica inlayer protection tube, this silica inlayer protection tube is located between this thermocouple wire and this the skin protective sheath. Use the utility model discloses a during the thermocouple, protective pipe sleeve establishes on the thermocouple wire with the silica inlayer, then inserts silica inlayer protection tube and thermocouple wire to the outer protective sheath in, and in the time of in with thermocouple attachment to coking stove, carbon monoxide that natural gas burning produced and the compound that contains sulphur, phosphorus get into back to the thermocouple in, at first react with silica, avoid it directly to overlook the thermocouple wire, play the effect of stabilizing the thermocouple and detecting precision and extension life.
Description
Technical field
The utility model relates to thermopair, more particularly, relates to the special platinum rhodium thermocouple of a kind of coking furnace.
Background technology
Thermopair, as a kind of temperature measurement tool, is widely used in the industrial production.At present; coking furnace adopts the mode of gas-firing to heat mostly; produce the compound of a certain amount of carbon monoxide and sulfur-bearing, phosphorus in the process of gas-firing thereupon; these materials contact in thermocouple wire through after the outer layer protective sleeve of thermopair along with vaporization at high temperature; thermocouple wire is corroded, thus affects service precision and the life-span of thermopair.
Utility model content
The technical problems to be solved in the utility model is, for the above-mentioned defect of prior art, provides a kind of coking furnace special platinum rhodium thermocouple.
The utility model solves the technical scheme that its technical matters adopts: construct the special platinum rhodium thermocouple of a kind of coking furnace; this thermopair comprises outer layer protective sleeve and is positioned at the thermocouple wire of this outer layer protective sleeve; this thermocouple wire is also arranged with silicon dioxide internal layer protection tube, this silicon dioxide internal layer protection tube is between this thermocouple wire and this outer layer protective sleeve.
In the special platinum rhodium thermocouple of coking furnace described in the utility model, this outer layer protective sleeve is ceramic corundum protective sleeve or silit protective sleeve.
In the special platinum rhodium thermocouple of coking furnace described in the utility model, this outer layer protective sleeve end is provided with the over cap removably connected with this outer layer protective sleeve, and this over cap is provided with bleeder vent.
In the special platinum rhodium thermocouple of coking furnace described in the utility model, this over cap is connected with this outer layer protective sleeve end thread.
Implement the special platinum rhodium thermocouple of coking furnace of the present utility model, there is following beneficial effect: when using thermopair of the present utility model, silicon dioxide internal layer protection tube is set on thermocouple wire, then silicon dioxide internal layer protection tube and thermocouple wire are inserted in outer layer protective sleeve, by in the installation of TC to coking furnace time, the carbon monoxide that combustion of natural gas produces and sulfur-bearing, the compound of phosphorus enters to after in thermopair, first react with silicon dioxide, it is avoided directly to overlook thermocouple wire, play steady heat galvanic couple accuracy of detection and the effect extending serviceable life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing:
Fig. 1 is the structural representation of the special platinum rhodium thermocouple of the utility model coking furnace.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
As shown in Figure 1; in coking furnace of the present utility model special platinum rhodium thermocouple first embodiment; this thermopair 1 comprises outer layer protective sleeve 2 and is positioned at the thermocouple wire 3 of this outer layer protective sleeve 2; this thermocouple wire 3 is also arranged with silicon dioxide internal layer protection tube 4, this silicon dioxide internal layer protection tube 4 is between this thermocouple wire 3 and this outer layer protective sleeve 2.
Understandable, the protection tube that this silicon dioxide internal layer protection tube 4 is made for earth silicon material.
When using thermopair 1 of the present utility model; silicon dioxide internal layer protection tube 4 is set on thermocouple wire 3; then silicon dioxide internal layer protection tube 4 and thermocouple wire 3 are inserted in outer layer protective sleeve 2; when thermopair 1 is mounted in coking furnace; the compound of the carbon monoxide that combustion of natural gas produces and sulfur-bearing, phosphorus enters to after in thermopair 1; first react with silicon dioxide; avoid it directly to overlook thermocouple wire 3, play steady heat galvanic couple 1 accuracy of detection and the effect extending serviceable life.
Further, this outer layer protective sleeve 2 is ceramic corundum protective sleeve or silit protective sleeve.
Further; for ease of changing silicon dioxide internal layer protection tube 4, and increasing thermopair 1 gas penetration potential, making thermopair 1 can detect ambient temperature fast; this outer layer protective sleeve 2 end is provided with the over cap 5 removably connected with this outer layer protective sleeve 2, and this over cap 5 is provided with bleeder vent 6.
Further, this over cap 5 is connected with this outer layer protective sleeve 2 end thread.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
