Description
Technical field
The utility model relates to a kind of telescopic compensator for sintering machine band large-scale metal flue, belongs to technical field of metallurgical equipment.
Background technology
When the band large-scale metal flue of sintering machine works, its temperature can change in the larger context, for preventing flue from producing larger internal stress because expanding with heat and contract with cold, needing flue to be divided into fixing flue and flexible flue, and installing telescopic compensator additional between.Such as, sintering machine main opium eating road has Φ 5000 compensator 2, Φ 4800 compensator 2, Φ 3400 compensator 2.Existing sintering machine flue telescopic compensator is all generally be made up of the compensator outer sleeve be coaxially arranged on outside fixing flue end and the ring-type Internal baffle be coaxially arranged on outside flexible flue end, ring-type Internal baffle coaxial package is inner at compensator outer sleeve, when flexible flue to expand because of variations in temperature or shrinks, the outer rim of ring-type Internal baffle is slided along the inwall of compensator outer sleeve, flue total length is remained unchanged, thus eliminates the internal stress of flue.But find in production process, by the restriction of manufacturing technology level, excesssive gap (2-6mm) between the outer rim of ring-type Internal baffle and compensator outer sleeve inwall, telescopic compensator sealing is very poor, and cause large flue to take out " wild wind " serious, sintering machine main opium eating road negative pressure is low, sintering deposit burning is insufficient, sinter return fine rate is high, has had a strong impact on output and the quality of sintering deposit, also result in main energy waste of taking out air-introduced machine simultaneously.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of large-scale flue telescopic compensator of improvement, thoroughly solves the sealing problem of band large-scale metal flue telescopic compensator.
Problem described in the utility model realizes with following technical proposals:
A kind of large-scale flue telescopic compensator, formation comprises and is arranged on compensator outer sleeve outside fixing flue end and coaxial with fixing flue, is arranged on outside flexible flue end and the ring-type Internal baffle coaxial with flexible flue and compensator sealing device, described compensator sealing device comprises the sealing plate support of looped flexible sealing plate and ring-type, described sealing plate support is coaxially fixed on ring-type Internal baffle, the inner edge of described looped flexible sealing plate is fixed in the cannelure of sealing plate support outer rim, and its outer rim withstands on the inwall of compensator outer sleeve.
Above-mentioned large-scale flue telescopic compensator, the looped flexible sealing plate of described compensator sealing device and sealing plate support are divided into multistage by the plane through its axis, and every section is fixedly connected with ring-type Internal baffle by self-tapping screw.
Above-mentioned large-scale flue telescopic compensator, described looped flexible sealing plate is ring-type needle spikesedge herb.
The utility model utilizes looped flexible sealing plate to seal the gap between ring-type Internal baffle and compensator outer sleeve, ensureing that flexible flue is retractile while, substantially increase the sealing property of compensator, thus improve the seed output and quality of sintering deposit, avoid the waste of the energy, reduce the production cost of sintering deposit.In addition, it is simple that the utility model also has structure, and easy for installation, the advantages such as reliable operation, are adapted to the band large-scale metal flue of various uses.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the scheme of installation of the utility model on flue;
Fig. 2 is A-A sectional view;
Fig. 3 is partial enlarged view.
In figure, mark is as follows: 1, fixing flue, and 2, compensator outer sleeve, 3, ring-type Internal baffle, 4, stretch flue, 5, sealing plate support, 6, looped flexible sealing plate, 7, compensator sealing device.
Detailed description of the invention
Referring to Fig. 1 ~ Fig. 3, sintering machine main opium eating road is divided into fixing flue 1 and flexible flue 4, and the end winding support of fixing flue 1 has compensator outer sleeve 2, and flexible flue 4 end winding support has ring-type Internal baffle 3.Gap between compensator outer sleeve 2 and ring-type Internal baffle 3 is 2-6mm.In order to eliminate the impact of this gap on compensator sealing, the utility model has been set up by looped flexible sealing plate 6(ring-type needle spikesedge herb on ring-type Internal baffle 3) and the compensator sealing device 7 that forms of sealing plate support 5, looped flexible sealing plate 6 and sealing plate support 5 are fixed on ring-type Internal baffle 3 by self-tapping screw segmentation, during installation, looped flexible sealing plate 6 and compensator outer sleeve 2 inwall are adjacent to, and realize the sealing of metal flue compensator.The utility model solves main opium eating road well and takes out " wild wind " seriously, affects the problem of the seed output and quality of sintering deposit.Making and the installation method of compensator sealing device 7 are as follows:
(1) first use the steel plate of 4mm, blanking makes the annular slab that width is 50mm, external diameter is slightly less than ring-type Internal baffle 3, blanking makes the annular solid that width is 30mm, cross section is " L " type again, by the two coaxial welding together, be made into the sealing plate support 5 that cross section is " h ", sealing plate support 5 bore the screw hole of ￠ 3.5mm.The looped flexible sealing plate 6(ring-type needle spikesedge herb of thick 15mm is placed in the cannelure of sealing plate support 5 outer rim), during installation, the outer rim of looped flexible sealing plate 6 and compensator outer sleeve 2 inwall are adjacent to, and realize the sealing of metal flue compensator.
(2) sintering machine main opium eating road compensator diameter is general all very large, and the Zhou Changda 10-16 rice of sealing plate support 5, for convenience of construction, carries out 8 deciles (referring to Fig. 1) to sealing plate support 5 and looped flexible sealing plate 6, then carry out segmentation installation.
Looped flexible sealing plate 6(ring-type needle spikesedge herb) wearing and tearing after, can change, to ensure the sealing property of flue compensator.
The direct economic benefit of the present embodiment: the utility model efficiently solves large flue and takes out " wild wind ", main negative pressure of taking out is low, and sintering deposit sintering is insufficient, and the rate of return mine is high, affects the problem of sintering output and quality.According to Continuous Observation statistics, after flue telescopic compensator improves, master takes out negative pressure and improves 0.6 Κ Pa, and sinter return fine rate reduces by 0.5%.Molten iron value=4800 ton per day × 0.5% × 365 day ÷ 1.66(ton iron ore consumption that annual fecund is raw) × 1200 yuan/ton=633.25 ten thousand yuan; Main exhauster saves electricity about 0.2% because negative pressure improves, the annual electricity charge=6400kw/h × 0.2% × 24h × 365 of saving day × 0.52 yuan/degree=5.8 ten thousand yuan.The raw direct benefit 633.25 ten thousand yuan+5.8 ten thousand yuan=639.05 ten thousand yuan of annual common property.
