Description
Technical field
The invention belongs to metallurgy industry sintered ring cool equipment field, relate generally to and improve 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 carrys out heat sinter on cooling chassis by the bellows air blast of chassis bottom, and the higher waste gas of temperature of cooling rear generation produces steam by waste heat boiler, and afterheat steam is used for generating electricity.The efficiency 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 declines, and can not produce the waste gas that temperature is higher directly affects generated energy, causes the waste of heat resource.
The effective ways that improve central cooler waste gas vapor (steam) temperature are, the further sealing effectiveness of both sides sealing device below raising circular cooler trolley, by the way raising central cooler waste gas residual heat temperature that reduces air leak rate of air curtain, the waste heat that central cooler is produced has obtained effectively making full use of.
The Sealing Technology great majority of both sides, existing circular cooler trolley bottom are movable sealing and static seal composition form, dynamic sealing rubber plate is synchronizeed together and is done gyration with slewing frame, movable sealing is arranged on lower breast board inner side, and rubber slab contacts and seals with the cone inclined-plane along inner side on bellows.Static seal rubber slab is arranged on bellows and maintains static along outside, and static seal contacts and seals with the lower seal plate of lower breast board.
The dynamic and static sealing plate of prior art all adopts sealing plate and the form that contacts 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, sealing effectiveness variation.After the sealing station of rubber slab is worn, whole rubber slab will be replaced, and take to utilize caoutchouc elasticity to be out of shape to compensate the method for rubber wearing and tearing, and cause and change frequent and operating cost raising.Even sealing plate is arranged under chassis on breast board,, there is the little and little problem of compensation rate of contact area in rubber slab and the plane garden dish plane contact of installing on bellows equally.
But central cooler diameter is larger, 360m
2the central cooler diameter that sintering machine mates will reach 44m, on bellows along the cone inclined-plane of inner side be difficult to make be arranged on central cooler under the dynamic sealing rubber plate running face of breast board inner side consistent, because the postrun actual center of circle of central cooler changes within the specific limits, cause dynamic sealing rubber plate sometimes can not with cone inclined-plane close contact, this just causes and leaks out, or sealed rubber plate contacts tension with cone inclined-plane, causes sealed rubber plate heavy wear or damage.
Revolving body bottom is the plane that multiple lower breast boards and chassis soffit are combined into, it is a rugged plane, be arranged on that on bellows, fixed static seal rubber slab contacts with one rugged along outside, not only sealing effectiveness is bad, and, once there is chassis wheel case accident, chassis soffit can be destroyed the static seal rubber slab touching or come off.
When discharging, the material on chassis both sides can flow out from lower breast board, and the dynamic sealing rubber plate that is arranged on lower breast board has played again the effect of blocking material, also very serious to the wearing and tearing of dynamic sealing rubber plate.
Above-mentioned prior art makes the inleakage of air intake system of circular cooler reach 40% left and right, 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 to improvement by a relatively large margin, to change the air blast of chassis side into by pallet bottom air blast, the multiple points of branch wind pipes that air draught house steward installs, wind is delivered to annular passage, annular passage arranges liquid tank outward, door shape sealing device covers on liquid tank, in the water of the inside and outside sealing plate insertion liquid tank under door shape sealing device, form sealing, a door shape sealing device is arranged on chassis side by 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 using, there is the problem that improvement expenses is higher and the transformation time is grown for domestic.Extremely frigid zones can not be suitable in the winter time, also exposes in hydraulic seal groove, to enter material and precipitate the problems such as not easy to clean, moisturizing, overflow in use.From the wind energy analysis that comes up, the central cooler wind energy loss that bellows are arranged on chassis below form is less, and the form of annular passage will be passed through repeatedly change of the wind, form water vibrations for fear of crossing Wind Volume, the droplet that vibrations are got up is brought chassis blast pipe into, and spoiler is set in annular passage, enters chassis entrance airduct when avoiding chassis discharging, the striker plate that also must be greater than in the setting of chassis entrance mineral aggregate angle of repose, above structure setting all significantly reduces the energy of 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 chassis inhomogeneous, compare cooling effect with the form of pallet bottom air intake and decline.
summary of the invention:
The object 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.
