The utility model effectively protects against dust deposition at the front end of the optical fiber or coking of the front end of the conduit, prolongs the service life of the optical fiber and reduces the use cost. Besides, the utility model has the advantages of simple on-site operation and convenient maintenance, and solves the problems that the optical fiber is liable to be broken and the on-site maintenance is complex.
Description
Technical field
The utility model relates to flame detection technique field, and is particularly a kind of by the dirt-proof boot assembly that fibre-optic catheter protected of optic fibre transmision light beam to flame detector.
Background technology
Because the changeable shape of boiler combustion, diversity with the coal variation, cause the boiler design burning inconsistent with Actual combustion, cause the coking of boiler-burner spout, the burner nozzle coking causes the coking of fire inspection conduit, the catheter proximal end coking, cause the front end radiation heat to increase, easily cause optical fiber to come unstuck, burn or the logical light rate of optical fiber under the degradation phenomenon, simultaneously owing to be easy to generate dust during boiler combustion, cause flame detector to produce no fiery signal and final boiler shutdown, cause heavy losses to power plant.Simultaneously, because optical fiber self cost is also than higher, therefore, effectively protect optical fiber, extended fiber serviceable life adopt rational structure, conduit easy to maintenance is very important.Yet the conduit that is using at present has two kinds of situations: 1, can protect the conduit of optical fiber, and also better to the cooling effect of optical fiber, can guarantee that substantially optical fiber uses 3-4, but can not effectively prevent optical fiber front end dust stratification and coking; 2, the conduit of coking can be prevented, but the normal serviceable life of optical fiber can not be guaranteed simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of flame detection fiber protection dirt-proof boot assembly, can protect the coking of optical fiber front end dust stratification and catheter proximal end effectively, and can extended fiber serviceable life, reduce use cost; Execute-in-place is simple simultaneously, is convenient to safeguard that optical fiber is fragile, the field maintemance complicated problems thereby solve preferably.
For achieving the above object, the technical solution of the utility model is:
A kind of flame detection fiber protection dirt-proof boot assembly is connected in protection fire inspection fibre-optic catheter, and it comprises that preceding top guide is sleeve-like configuration, and it comprises that fixed part, the connecting portion that extends to form from fixed part reach the leading section that extends to form from connecting portion; The tapered design of described connecting portion; Described leading section outer rim design has zigzag structure; Abutment ring, it comprises sheathed outer shroud and the sheathed interior ring that is connected in described conduit that is connected in described preceding top guide fixed part, interior ring is arranged at outer shroud one side; Heat insulation fixture is arranged between preceding top guide and the abutment ring outer shroud.
Further, also offer through hole on the connecting portion of described preceding top guide.
Zigzag structure extends along leading section outer circle designs on the described preceding top guide leading section.
Again, also have first groove, second groove for fixing heat insulation fixture before described on the side of the end face of the corresponding abutment ring outer shroud of the fixed part of top guide diapire and corresponding abutment ring outer shroud madial wall, heat insulation fixture is positioned in this first, second groove.
In addition, the outer shroud that the utility model passes abutment ring by coupling bolt be connected in described before heat insulation fixture in top guide fixed part first groove, abutment ring and preceding top guide are connected and fixed.
Described heat insulation fixture is cylindrical.
Described abutment ring is threaded with conduit.
The preceding top guide of the utility model dirt-proof boot assembly has serrate design on the leading section, be not easy to coking on preceding top guide after making the burner hearth internal combustion; Before top guide tapered design in design process, can effectively prevent dust accumulation after the boiler internal combustion at preceding top guide, even before having part to accumulate on the top guide, but, can allow secondary air blow away top dust stratification rapidly owing to have through hole on the preceding top guide.
In addition, the tapering before and after the preceding top guide utilization and the size of contact area, the temperature before and after making can effectively reduce.
Heat insulation fixture, top guide does not directly contact with abutment ring before making, and avoids the heat transmission situation of directly contact to produce.This heat insulation fixture preferably ceramic material utilizes ceramic insulativity.
Advantage of the present utility model is,
The utility model dirt-proof boot assembly has solved the fiber optic protection and the fibre-optic catheter coking problem of transmitting beam in the flame detector.The junction is heat insulation fixture before and after utilizing--insulating ceramics and minimizing conduit and front end contact area reduce fire inspection catheter proximal end temperature, inner catheter and optical fiber are cooled off, simultaneously because the design of the serrate of preceding top guide is not easy to the coking of fire inspection conduit.
The mode that the inner reduction of the utility model employing radiation temperature is cooled off will be increased to the protection period of optical fiber 6～8 years fiber optic protection.
