Abstract
The heat-treatment furnace radiant tube UV checkout gear of easy cleaning dust stratification, form primarily of UV straight tube, the cooling duct be connected with UV straight tube, the UV detector holder being connected to UV straight tube end, the UV detector that is connected with UV detector holder, it is: on UV straight tube, be connected with scavenging conduit, scavenging conduit is equipped with gas container, UV straight tube before and after gas container is equipped with air intake switch and air-out switch, is connected with manual compression source of the gas device in scavenging conduit import department.The utility model adopts the mode of portable manual pressurization, and the compression pressure of generation can higher than existing industrial gases at high pressure, and purge better effects if to the dust stratification of attachment in UV pipe, structure is simple, uses flexible and convenient, can meet UV probe and receive precise requirements.
Description
Technical field
The utility model relates to heat-treatment furnace radiant tube UV checkout gear, specifically belongs to the heat-treatment furnace radiant tube UV checkout gear of easy cleaning dust stratification chance.
Background technology
In band steel continuous heat, adopt automatic ignition radiation pipe burner tip must ensure the reliability of flame ignition and flame monitoring.Flame monitoring mainly contains two kinds of modes, UV monitoring and ionic flame monitoring.
UV flame monitor is electronic instrument, can be no more than 60 DEG C by tolerable temperature, generally all need to arrange cooling device.Current cooling from main combustion air, draws a part pass in UV monitoring pipe, and the high-temperature combustion gas of altering in radiant tube by the cooling of UV probe, blows back in radiant tube, prevents UV probe temperature overheated by the other hand.But after burner longtime running, because the impurity such as the ambient dust that air brings can attachedly gradually amass on UV inside pipe wall, the ultraviolet light with scattering flame emission can be absorbed, interference is caused to the UV flame ultraviolet ray intensity signal received of popping one's head in, cause flare up fire decay, distortion, thus warning automatically shuts down burner.For head it off, normally regular compressed air or nitrogen purge UV monitoring pipe, utilize pressure-air or nitrogen to be blown away by attached for UV inside pipe wall long-pending dust.But this method needs to arrange high-pressure gas pipeline system, adds equipment investment, and due to pipeline too complex, considerably increase the workload of equipment regular maintenance, on the other hand, industrial high-pressure blowing gas pressure is generally only 4 ~ 6kg/cm
2, effect is purged for the dust stratification adhered in UV pipe sometimes unsatisfactory.Another method arranges filter in air duct, falls to ensure to receive the stable of flare up fire by the filtering dust in cooling-air.Cooling blower and airstrainer is provided with separately for flame monitoring probe in paper " the maintenance and application strategy of flame detector system ", but, airstrainer easily blocks and causes cooling air quantity less and burn out UV monitor, and disassembly, cleaning trouble, safeguards that labour intensity is large.
Utility model content
The purpose of this utility model is the deficiency overcoming prior art existence, a kind of dust stratification convenience of clearing up the attachment of UV inside pipe wall is provided, use flexible, easy, structure is simple, can meet the heat-treatment furnace radiant tube UV checkout gear that UV probe receives the easy cleaning dust stratification of precise requirements.
Realize the technical measures of above-mentioned purpose:
The heat-treatment furnace radiant tube UV checkout gear of easy cleaning dust stratification, form primarily of UV straight tube, the cooling duct be connected with UV straight tube, the UV detector holder being connected to UV straight tube end, the UV detector that is connected with UV detector holder, it is: on UV straight tube, be connected with scavenging conduit, scavenging conduit is equipped with gas container, UV straight tube before and after gas container is equipped with air intake switch and air-out switch, is connected with manual compression source of the gas device in scavenging conduit import department.
It is: on gas container, be connected with Pressure gauge.
Feature of the present utility model: the mode adopting portable manual pressurization, the compression pressure produced can higher than existing industrial gases at high pressure, and purge better effects if to the dust stratification of attachment in UV pipe, structure is simple, use flexible and convenient, UV probe can be met and receive precise requirements.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-UV straight tube, 2-cooling duct, 3-UV detector holder, 4-UV detector, 5-scavenging conduit, 6-gas container, 7-air intake switch, 8-air-out switch, 9-manual compression source of the gas device, 10-Pressure gauge.
Detailed description of the invention
Be described further below in conjunction with accompanying drawing:
The heating furnace radiant tube UV checkout gear of easy cleaning dust stratification chance, form primarily of UV straight tube 1, the cooling duct 2 be connected with UV straight tube 1, the UV detector holder 3 being connected to UV straight tube 1 end, the UV detector 4 that is connected with UV detector holder 3, it welds scavenging conduit 5 on UV straight tube 1, scavenging conduit 5 is installed gas container 6, UV straight tube 1 before gas container 6 installs air intake switch 7, UV straight tube 1 after gas container 6 installs air-out switch 8, connects manual compression source of the gas device 9 in scavenging conduit 5 import department by joint.Separately on gas container 6, be connected with Pressure gauge 10.
When dust stratification in UV straight tube 1 needs to remove, first opened by air intake switch 7, manually compressed gas source device 9 is by air compressing, and inputs in gas container 6, until the pressure in gas container 6 reaches setting value; Then stop input compressed-air, and close air intake switch 7; After open air-out switch 8, make compressed air rush in rapidly in UV straight tube 1, the dust stratification of UV straight tube 1 inside pipe wall washed away and discharges outside UV straight tube 1, until the dust stratification of UV straight tube 1 inside pipe wall is removed clean.When compressed gas in gas container 6 is finished still for removing clean by dust stratification, continue to repeat above-mentioned action until reach requirement position.
This detailed description of the invention is only the best and exemplifies, the restricted enforcement not to technical solutions of the utility model.
