The cooling heat radiation device that is used for the flame detector of the utility model guarantees that the flame detector can work within the normal working temperature range, thereby improving the service life of the flame detector.
Description
Technical field
The utility model relates to a kind of flame detector with steel annealing, particularly a kind of flame detector cooling heat radiator.
Background technology
The annealing of band steel is the important production process together that cold-rolled products are produced, and the band steel that its main task changes for the internal stress that the milling train operation is produced carries out annealing recrystallization to be handled, and uses for the later process unit, produces various cold-rolled products.
At present, the annealing process technical equipment of band steel mainly adopts bell-type annealing and unit annealing continuously, in annealing process, all need to heat by burner combustion, the existing bell furnace of cold rolling mill, its heating mantles mainly is by the mode that burner combustion heats coil of strip to be heated when work, and the flame detection is the requisite measure that guarantees the burner trouble free service, the principle of work that ultraviolet flame detects is by the ultraviolet model in the detection of the ultraviolet detector on the detector tube that the is installed in heating mantles burner position burner flame, thereby the effect of security control is played in the action of control gas valve.
The scheme of installation of existing flame detector as shown in Figure 1, flame detecting device comprises flame detector tube 2, cooling air interface 3, quartz glass erector 4, quartz glass 5, quartz glass retaining ring 6, flame detector 7.Heating mantles 1 is connected with flame detector tube 2, flame detector 7 directly is connected on the quartz glass erector 4, and flame detector tube 2 is steel constructions, quartz glass erector 4 is steel structures, in 1 heating period of heating mantles, when the heating case temperature has arrived hot stage and has reached 850 degrees centigrade, heat conduction by flame detector tube 2 and quartz glass erector 4, heat is directly delivered on the flame detector 7, intrinsic air-cooled structure only can completely cut off the radiation thermal conduction of hot-air, and it is very little to heat transferred blocking effect by metal pipe-wall, not only make quartz glass be subjected to high temperature cracked, and flame detector bears high-temperature baking, its surface temperature can reach 120 degrees centigrade even higher by actual measurement, surpassed-5 ℃～80 ℃ the operating temperature range that flame detector allows, cause its inner components and parts aging rapidly, even electric plate is by burned, make the detection signal fault, cause burner to close, thereby cause the heating mantles temperature-rise period undesired, have a strong impact on the performance of production capacity, cause the flame detector life-span to reduce simultaneously.The design of the quartz glass retaining ring of the quartz glass erector of prior art is not easy to replacing and the cleaning to quartz glass in addition, has strengthened the maintenance work difficulty.
Summary of the invention
In order to address the above problem, the utility model provides a kind of flame detector cooling heat radiator, reduces the heat that conducts to the cooling device rear end by the detector tube tube wall effectively, prevents that flame detector is damaged by high temperature and quartz glass is subjected to high temperature cracked.
Another purpose of the present utility model is by improving the mounting means of quartz glass, being convenient to the maintenance of quartz glass.
For achieving the above object, a kind of flame detector cooling heat radiator of the present utility model comprises cylindrical shell 11, ring-type radiating fin 12 and ring-type cooling water cavity 13, described ring-type radiating fin 12 is positioned at the outside surface of cylindrical shell 11, and described ring-type cooling water cavity 13 is arranged in the cylindrical shell 11.
The terminal inner ring of described cylindrical shell 11 is provided with the mounting groove 18 of quartz glass 20, and described quartz glass 20 usefulness bail wires 19 are fixed in the mounting groove 18; The terminal outer ring of described cylindrical shell 11 is provided with the binding groove 16 of flame detector 7, and described flame detector 7 is fastening by screw 17.
The material of described cylindrical shell 11 and ring-type radiating fin 12 is an aluminium.
Flame detector of the present utility model has taken into full account the actual heat exchange situation of flame detector tube with cooling heat radiator, stop the heat that transmits by the detector tube tube wall effectively, and the radiation heat by detector tube is by air-cooled isolation the of the prior art, this is with regard to having prevented in the actual production flame detector effectively and being subjected to high temperature and damage and be subjected to high temperature with quartz glass and cracked situation takes place, effectively improve the work efficiency of heating mantles burner in heating process, promoted production capacity, and guaranteed that simultaneously flame detector working in normal operating temperature range, improved the serviceable life of flame detector, and improved the mounting means of quartz glass, be convenient to cleaning, reduced maintenance workload effectively.
