Description
Technical field
The invention belongs to metallurgy industry sintered ring cool equipment field, relate generally to and improve the central cooler cooling effectiveness, improve the cold UTILIZATION OF VESIDUAL HEAT IN of ring, the spacing elastic sealing device of breast board three-dimensional under a kind of circular cooler trolley of reduction central cooler accident rate.
Technical background
In iron and steel metallurgical industry central cooler production process, central cooler cools off heat sinter on the chassis by the bellows air blast of chassis bottom, and the higher waste gas of temperature that produces after the cooling produces steam by waste heat boiler, and afterheat steam is used for generating electricity.The efficient of the serious restriction of the sealing quality central cooler waste heat recovery of central cooler.The bad heat sinter cooling effectiveness that will cause of sealing effectiveness descends, and can not produce the higher waste gas of temperature directly affects generated energy, causes the waste of heat resource.
The effective ways that improve central cooler waste gas vapor (steam) temperature are, the sealing effectiveness of both sides sealing device below the further raising circular cooler trolley, improve central cooler waste gas residual heat temperature with the way that reduces air leak rate of air curtain, the waste heat that central cooler is produced has obtained effectively taking full advantage of.
The Sealing Technology great majority of existing both sides, circular cooler trolley bottom are movable sealing and static seal composition form, the dynamic sealing rubber plate is done gyration synchronously with slewing frame, it is inboard that movable sealing is installed in lower breast board, contacts along the cone inclined-plane of inboard on rubber slab and the bellows to seal.The static seal rubber slab is installed on the bellows and maintains static along the outside, and static seal contacts with the lower seal plate of lower breast board and seals.
The dynamic and static sealing plate of prior art all adopts sealing plate and the form that contacts the sealing surface inclination, the elasticity that distortion produces by rubber slab seals, and its subject matter is that contact area is less, and the rate of wear is very fast, the deflection of rubber slab reduces diminishes contact force, the sealing effectiveness variation.After the sealing station of rubber slab is worn, whole rubber slab will be replaced, take to utilize caoutchouc elasticity to be out of shape to compensate the method for rubber wearing and tearing, cause and change frequent and the operating cost raising.Even sealing plate is installed under the chassis on the breast board, the little and little problem of compensation rate of contact area appears in rubber slab and in garden, the plane dish plane contact that bellows are installed equally.
But the central cooler diameter is larger, 360m
2The central cooler diameter that sintering machine mates will reach 44m, on the bellows along inboard cone inclined-plane be difficult to make be installed in central cooler under the dynamic sealing rubber plate running face of breast board inboard consistent, because the postrun actual center of circle of central cooler changes within the specific limits, cause the dynamic sealing rubber plate sometimes can not with cone inclined-plane close contact, this just causes and leaks out, perhaps sealed rubber plate contacts tension with the cone inclined-plane, causes sealed rubber plate heavy wear or damage.
Central cooler revolving body bottom is the plane that a plurality of lower breast boards and chassis soffit are combined into, it is a rugged plane, be installed in that fixed static seal rubber slab contacts with one rugged along the outside on the bellows, not only sealing effectiveness is bad, and, in case when chassis wheel case accident occurring, can destroy the static seal rubber slab that touches or come off in the chassis soffit.
The material on chassis both sides can flow out from lower breast board during discharging, and the dynamic sealing rubber plate that is installed in lower breast board has played again the effect of blocking material, and is also very serious to the wearing and tearing of dynamic sealing rubber plate.
Above-mentioned prior art reaches about 40% the inleakage of air intake system of circular cooler, causes serious energy waste and environmental pollution, becomes metallurgy industry sintered ring cool equipment field urgent need to solve the problem.
For solving this difficult problem, patent " a kind of air intake system of circular cooler and annular passage thereof " 200810167969.2, the version of central cooler has been carried out improvement by a relatively large margin, to change the air blast of chassis side into by the pallet bottom air blast, the a plurality of minutes branch wind pipes that the air draught house steward installs, wind is delivered to annular passage, annular passage arranges liquid tank outward, door shape sealing device covers on the liquid tank, form sealing in the water of the inside and outside sealing plate insertion liquid tank under the door shape sealing device, a door shape sealing device is installed on the chassis side by the chassis blast pipe.This hydraulic seal form sealing effectiveness is greatly improved.But this technology is only applicable to newly-built central cooler, in a large number at the central cooler that uses, has the problem that improvement expenses is higher and the transformation time is long for domestic.Extremely frigid zones can not be suitable in the winter time, also exposes in the use to advance material in the hydraulic seal groove and precipitate the not problems such as easy to clean, moisturizing, overflow.From the wind energy analysis that comes up, bellows are arranged on the central cooler wind energy of chassis below form and lose less, and the form of annular passage will be passed through repeatedly change of the wind, form the water vibrations for fear of crossing Wind Volume, the droplet that vibrations are got up is brought the chassis blast pipe into, and spoiler is set in annular passage, enters chassis entrance airduct when avoiding the chassis discharging, also must be at the striker plate of chassis entrance setting greater than the mineral aggregate angle of repose, above structure arranges all energy of decrease wind.This air intake form is compared sealing effectiveness with the form of pallet bottom air intake raising, but energy consumption also increases.
From the form of chassis side air inlet, cause the cooling air quantity that heat sinter passes through from the chassis inhomogeneous, compare cooling effect with the form of pallet bottom air intake and descend.
Summary of the invention:
The purpose of this invention is to provide a kind of good sealing effect, improve the site environment of central cooler, the spacing elastic sealing device of breast board three-dimensional under the reliable circular cooler trolley of equipment.
Technical scheme of the present invention is to realize like this.
