Description
Technical field
The utility model relates to a kind of motion compensator, and a kind of dry coke quenching high-temperature compensator of more specifically saying so is suitable for the dried bit shift compensation that puts out stove closed circulation blast heater of steel mill.
Background technology
At present, the coke quenching of steel mill's coking furnace is adopted water to put out method usually and is carried out coke production.It is the red-hot coke that coking furnace is produced that water puts out method, and the water spray is watered and made its cooling form coke.This water puts out that law technology is backward, water loss is big, makes a large amount of heat energy follow steam to run away, and has caused the waste of the energy, and air and surrounding enviroment have been brought huge pollution.For addressing the above problem, also have at present and adopt the dried stove that puts out to carry out the dried method of putting out and cool off fast and produce coke.The dried method of putting out at first adopts high wind to impel the cooling of coke fast cooling to the dried red-hot coke that puts out in the stove, and the overfire air that will carry the coke heat is again sent into waste heat boiler by disposable dust remover.Like this, both can make heat energy obtain recycling, and save water resources again, and eliminated pollution air and surrounding enviroment.But, because dried in the dry coke quenching recycle system puts out rigid connection between stove, disposable dust remover and the waste heat boiler equipment, constraint mutually, being subjected to pyritous to influence self thermal expansion amount can't discharge, the internal stress that produces easily forms three-D displacement, has influenced the work-ing life of dry coke quenching circulating air equipment greatly.
Summary of the invention
The purpose of this utility model provides a kind of dry coke quenching high-temperature compensator, it not only can make heat energy recycle, save water resources, decontamination, and can absorb three-D displacement, elimination internal stress, the service life of equipment that improves that the thermal expansion of dry coke quenching circulating air equipment causes.
The purpose of this utility model is achieved in that it comprises flange and is fixed on corrugated tube on the flange by adapter, it is characterized in that being provided with in the corrugated tube inside lining sleeves of two band displacement seams, and two inside lining sleeves are fixed on the flange of the left and right sides by outer rim respectively; The first sealing bore block is sewed in the displacement of inside lining sleeve, and an one end and a sidelining tube are fixed; One group of L shaped plate is arranged on second sealing bore, and second sealing bore is fixed by a L shaped plate and a sidelining tube, between second sealing bore and first sealing bore sealed insulation layer is arranged; Be fixed with the weldering pawl on the intracavity sidewall of loop expansion pipe, the thermofin that has the displacement seam is fixed on the sidewall of loop expansion pipe inner chamber by the weldering pawl.
The utility model has the advantages that owing to be provided with the inside lining sleeve of band displacement seam in the corrugated tube, two inside lining sleeves are fixed on the flange of the left and right sides by outer rim respectively; Sew in the displacement of inside lining sleeve and also to be provided with two-layer sealing bore, make loop expansion pipe form the heat insulation and free displacement structure of compensation of labyrinth seal; Again owing on the intracavity sidewall of loop expansion pipe, be fixed with the weldering pawl, the thermofin that has the displacement seam is fixed on the sidewall of loop expansion pipe inner chamber by the weldering pawl, the heat-proof quality of loop expansion pipe is good, thermofin difficult drop-off, long service life, it can not only absorb three grades of displacements that the thermal expansion of dry coke quenching closed circulation equipment causes, the generation of avoiding internal stress, and the work-ing life that can improve dry coke quenching circulating air equipment greatly.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a concrete structure synoptic diagram of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to view.
Embodiment
In Fig. 1-2, loop expansion pipe is a rectangle, and the arc that arches upward is arranged at its top.About two flange 1 usefulness steel plates make rectangle, be the arc that arches upward at the top margin of rectangular flange 1, take over the 16 symmetric inboards that are welded on left and right sides flange 1 for two and cooperate with flange 1.Corrugated tube 5 two ends that its top has an arc that arches upward respectively by take over 16 be welded on about on two flanges 1.Displacement seam is arranged between two identical inside lining sleeves 13,15, the outer rim of two inside lining sleeves 13,15 in corrugated tube 5 respectively with about the inner edge welding of two flanges 1, on inside lining sleeve 13,15, be welded with one group of equally distributed stiffening web 6 for increasing bending strength.7 block of first sealing bore are sewed in the displacement of interior village tube 13,15, tube 13 welding in village's in one end limit and the right side.Can be free to slide expansion displacement mutually at the outside surface of the interior village 15 and first sealing bore 7 in order to absorption equipment.One group of L shaped plate is welded at the two ends of the second sealing letter 8 respectively.Between the second envelope tube 8 and first sealing bore 7 sealed insulation layer is arranged, the one end is fixing by L shaped plate and 13 welding of right side inside lining sleeve.The inner chamber of loop expansion pipe have be vertically welded in respectively in village's tube 13,15, and second sealing bore 8 on, equally distributed weldering pawl 11, weldering pawl 11 usefulness have the reinforcing bar of certain intensity and make Y shape, in order to fix first thermofin 2 and second thermofin 3.About two pipe connectings 18 be welded on respectively on the outer side of left and right sides flange 1, in order to increase the intensity of flange 1, on flange 1, also be welded with stiffening web 9,17.Overheated for preventing corrugated tube 5, in the cavity that corrugated tube 5 and inside lining sleeve 13,15 surround, be filled with ceramic fiber blanket elasticity thermofin 10.Inner chamber at loop expansion pipe is filled with first thermofin 2 and second thermofin 3, and is all fixing by weldering pawl 11.Displacement seam is arranged on first thermofin 2 and second thermofin 3 equally, be inserted with one group and arrange the U-shaped elasticity protecting cover 14 that connects mutually in the displacement seam, elasticity protecting cover 14 is fixed by the screw rod on second sealing bore 8.Bottom at loop expansion pipe also is covered with refractory brick thermofin 4.
